The present study showed that percent germination, radicle and plumule lengths of Brassica juncea were adversely affected by increasing the level of salinity. As compared to 95 per cent germination of the control, there were 92.50. 90.00. 90.00, 85.00, 87.50 and 80.00 per cent germinations respectively at 2.5, 5.0, 7.5. 10.0. 12.5 and 15.0 dSm/sup -1/ NaCI salinity levels. Similarly. all the parameters tested in the pot experiments showed gradual decline with the corresponding increasing levels of NaCl salinity. At lower levels of salinity (2.5 and 5.0 dSm/sup -l/), Brassica juncea had reasonably good growth and productivity. It showed greatly reduced growth and at 7.5 and 10.0 dSm/sup -1/ while at 12.5 and 15.0 10.0 dSm/sup -1/ salinity levels it was severely production affected. It is concluded from the present work that Brassica juncea can be grown fairly on mild saline soils for a food, fodder and seed production. (author)

Full Text Available Abstract. A laboratory analysis was conducted to evaluate the chemical composition of raw and differently processed Senna obtusifolia seed meal. Senna obtusifolia seeds were processed using boiling, soaking, sprouting and fermentation methods respectively. The processed and raw seed meals were milled and the representative seed meal samples were analysed using standard laboratory methods. The results of the chemical analysis revealed that Senna obtusifolia seed meal possessed good nutritional properties (23.40 – 25.90% crude protein and 2.14 – 2.86 MJ/kg metabolizable energy and has good amino acid profile as an alternative feed source for livestock. However, the raw seed meal contains 378.5, 247.2, 102.0, 248.6 and 190.0 mg/100.0g of tannins, phytates, oxalate, alkaloids and saponins, respectively. The different processing methods were observed to be effective in reducing the level of the antinutrients with fermentation recording the highest reduction levels of 68.25, 66.32, 43.70, 58.07 and 44.30% for tannins, phytates, oxalate, alkaloids and saponins followed by boiling with reduction levels of 66.27, 46.97, 46.97, 47.89, 58.66 and 45.78% for tannins, phytates, oxalate, alkaloids and saponins, respectively. In conclusion, Senna obtusifolia seed can be effectively process for utilization as feed ingredient using fermentation. Feeding trial should be conducted using Senna obtusifolia seed meal to evaluate the feeding value in livestock especially monogastric animals

The accumulation of excess Cd in the seeds of cereal and other crops compromises their commercial value and presents a potential risk to human health. Indian mustard [Brassica juncea (L.) Czern.] is a moderate accumulator of heavy metals such as Cd and Zn, and the seeds are consumed throughout the world, particularly in the Indian subcontinent. The study here examined the transport of Cd into Indian mustard plants and to seeds as a function of external Cd and the stage of the life cycle (vegetative growth, flowering and seed set) to identify critical developmental windows where transport from roots to seeds was the greatest. Plants were also treated simultaneously with Zn to determine if Zn fertilization mitigated the transport of Cd to seeds. Plants treated with Cd during the seed set accumulated the highest concentrations of Cd, exceeding 8 mg kg(-1) dry weight in some instances. Cadmium accumulated during vegetative growth was not highly redistributed to seeds. No effects of Zn were observed with regard to Cd redistribution to seeds. This may be because of the relatively small Zn : Cd ratios tested. However, the results suggest that if Zn fertilization is to be used to reduce the Cd accumulation in seeds of this species, that plants should be treated during the seed set stage. As the seeds of Indian mustard consistently accumulated Cd to concentrations that exceed acceptable limits for food crops, additional study of Cd redistribution in this species is warranted.

Six hundred and forty one-day-old layer chicks were used to investigate the effect of replacing soybean meal with undecorticated sunflower seed meal protein for protein at 0, 25, 50, and 75% levels. Diets were without enzyme supplementation or with enzyme supplementation with four replications of twenty birds. Growth performance and nutrient utilization were determined. Proximate composition of the undecorticated sunflower seed meal used revealed that undecorticated sunflower seed meal contained 925.9, 204.5, 336.2, 215.1, 52.0 and 192.2g/kg dry matter, crude protein, ether extract, crude fibre, ash and soluble carbohydrates, respectively. Results showed that the final weight of 484.4 g/bird was obtained for birds on 75% undecorticated sunflower seed meal diet, while the lowest value of 472.2g/bird was obtained for birds on 25% undecorticated sunflower seed meal diet. Weight gain per bird per day was not significantly (P > 0.05) affected as the level of undecorticated sunflower seed meal increased in the diets. Feed intake per bird per day increased (P meal inclusion in the diet. However, enzyme supplementation of the diets showed marked (P meal inclusion in the diet while crude protein digestibility progressively reduced (P meal increased in the diet. Ash digestibility values were, however, increased (P meal increased in the diets. Birds on enzyme-supplemented diets consistently showed superior (P meal in the diets of layer chicks showed a similar body weight gain/bird/day with the control. Undecorticated sunflower seed meal used in this study is a good source of crude protein, ether extract, and amino acids and had the potential to serve as feeding stuffs as replacement for soybeans. The nutritive value of undecorticated sunflower seed meal was improved for layer chicks with exogenous enzyme supplementation. © 2015 Poultry Science Association Inc.

The major hurdles in successful in vitro transformation of Brassica juncea through standard tissue culture (STC) method are: culture contamination, somaclonal variations, and lack of expertise. Moreover, the current STC method is time consuming and needs continuous electricity. In the present study, the in planta transformation method through floral dip with or without vacuum infiltration was optimized for successful transformation of B. juncea. The B. juncea CV RAYA Anmol was used for transformation through Agrobacterium tumefaciens strain GV3101 harboring the binary vector plasmid pBinGlyBar4-EADcT. Based on the resistance reaction to the herbicide Basta, 20 and 40 resistant seedlings were obtained from 2000 seed germinated from the plants transformed through floral dip and vacuum infiltration methods, respectively. The PCR analyses further confirmed the presence of transgene in 3 floral dipped plants without vacuum infiltration and 17 floral dipped plants with vacuum infiltration, giving the transformation frequencies of 1.5*10/sup -3/ and 8.5*10/sup -3/, respectively. This method, which avoids tissue culture, will reduce the somaclonal variation accompanying prolonged culture of cells in a dedifferentiated state, will facilitate functional genomics and improvement of Brassica juncea with novel desirable traits while reducing time and expense.

Rat bioassays were conducted to study the effects of different processing methods on the nutritive value of rape seed meal. Treatments given to rape seed were irradiation alone, irradiation + autoclaving, irradiation + dry heating and sprouting. Results revealed that feeding rape seed as the sole source of dietary protein resulted in severe weight loss with control as well as all the treated samples. However, replacing half the maintenance level protein with wheat resulted in remarkable improvement in the nutritional quality of meal. There were weigh gains in all the groups. Weight gains were 32.15, 20.06, 17.36, 34.00, 19.93 and 26.27 g/rat in casein, control, sprouting, radiation, radiation + heat and radiation + autoclving groups, respectively. Protein efficiency ratios (PER) when adjusted to casein, were 2.10 for radiation + autoclaving and 2.03 for sprouting. Protein digestibility ranged from 92.68 to 96.79% among all the rape seed groups as compared to 97.77% for casein. Among organs, heart weight was influenced most by different diets (0.43 to 0.48% of body weight), while differences in weights of lungs, liver, spleen and kidney were negligible. (author)

Full Text Available Low temperature is a major abiotic stress that impedes plant growth and development. Brassica juncea is an economically important oil seed crop and is sensitive to freezing stress during pod filling subsequently leading to abortion of seeds. To understand the cold stress mediated global perturbations in gene expression, whole transcriptome of B. juncea siliques that were exposed to sub-optimal temperature was sequenced. Manually self-pollinated siliques at different stages of development were subjected to either short (6 h or long (12 h durations of chilling stress followed by construction of RNA-seq libraries and deep sequencing using Illumina’s NGS platform. De-novo assembly of B. juncea transcriptome resulted in 133641 transcripts, whose combined length was 117 Mb and N50 value was 1428 bp. We identified 13342 differentially regulated transcripts by pair-wise comparison of 18 transcriptome libraries. Hierarchical clustering of these differentially expressed transcripts along with Spearman correlation analysis identified two major clusters representing early (5-15 DAP and late stages (20-30 DAP of silique development. Detailed analysis led to the discovery of two gene expression clusters whose transcripts were inducible at both durations of the cold stress irrespective of the developmental stages. We further explored the expression patterns of gene families encoding for transcription factors (TFs, transcription regulators (TRs and kinases, and found that cold stress induced protein kinases specifically during early silique development. We validated the digital gene expression profiles of selected transcripts by qPCR and found a high degree of concordance between the two analyses. To our knowledge this is the first report of transcriptome sequencing of cold-stressed B. juncea siliques. The data generated in this study would be a valuable resource for not only understanding the cold stress signaling pathway but also for introducing cold

Full Text Available The study reported herein evaluates with rats the nutritional quality of raw and roasted kenaf seed as sources of nitrogen. Some safety aspects regarding possible feed use were also investigated. Wistar rats were fed four purified diets viz: a basal diet (nitrogen-free, a reference diet that contains casein and two diets made of kenaf seeds. Dietary treatments significantly influenced performance, biological indices and blood parameters (P<0.05. The performance of rats on kenaf based diets was inferior to that of rats on casein diets. The levels of serum glucose were significantly elevated for rats on kenaf based diets compared to rats on casein diet. However, the levels of serum total protein, globulin and albumin/globulin ratio were significantly elevated for rats on the casein diet compared to rats on kenaf based diets. Among the kenaf test proteins, Protein Efficiency Ratio (PER values of 1.87 and 1.65; Net Protein Ratio (NPR values of 0.56 and 0.50; Biological Value (BV of 65.04 and 63.05 and Net Protein Utilization (NPU values of 44.23 and 42.56 were obtained respectively for a raw kenaf seed meal RKM and roasted kenaf seed meal (HKM. There was no significant difference in results obtained for both RKM and HKM.

Changes in the glucosinolate-myrosinase defense system in Brassica juncea cotyledons during seedling development.

2002-02-01

Optimal defense theory (ODT) predicts that plant defenses will be allocated to plant organs and tissues in proportion to their relative fitness values and susceptibilities to attack. This study was designed to test ODT predictions on the myrosinase-glucosinolate defense system in Brassica juncea by examining the relationships between the fitness value of B. juncea cotyledons and the levels and effectiveness of cotyledon defenses. Specifically, we estimated fitness value of cotyledons during plant development by measuring plant growth and seed production after cotyledon damage or removal at successive seedling ages. Cotyledon removal within five days of emergence had a significant impact on growth and seed production, but cotyledon removal at later stages did not. Consistent with ODT, glucosinolate and myrosinase levels in cotyledons also declined with seedling age, as did relative defenses against a generalist herbivore, Spodoptera eridania, as estimated by bioassay. Declines in glucosinolates were as predicted by a passive, allometric dilution model based on cotyledon expansion. Declines in myrosinase activity were significantly more gradual than predicted by allometric dilution, suggesting active retention of myrosinase activity as young cotyledons expand.

Full Text Available Chrysoperla externa (Neuroptera: Chrysopidae larvae can avoid foraging on plants of Crotalaria juncea (Fabaceae after the issuance of floral buds, when the prey of Utetheisa ornatrix (Lepidoptera: Arctiidae incorporate toxic pyrrolizidine alkaloids from this plant. This reduces the predation and favors increasing the number of adults and eggs of this defoliator on crops of this plant. The aim of the present paper was to evaluate some biological and ecological aspects of C. externa and U. ornatrix on the organic crop of C. juncea in the EMBRAPA Maize and Sorghum in Sete Lagoas, Minas Gerais State, Brazil. Chrysoperla externa and U. ornatrix were more abundant in the vegetative and flowering stages of C. juncea, respectively, with caterpillars of this defoliator feeding on leaves and seeds of this plant. The duration of the stages/instars, survival, lifetime fecundity, and oviposition showed that the branches of C. juncea are a suitable food for U. ornatrix. The abundance of adults and larvae of C. externa was lower in the flowering and pods stages of C. juncea, respectively, when the postures of U. ornatrix are present, probably due to the toxicity of the eggs of this prey to this predator. During these stages, C. externa may be reared with alternative hosts, and when the crops of C. juncea are scarce, an artificial diet should be used for rearing this defoliator in the laboratory for biological research and the development of biological control tactics.Larvas de Chrysoperla externa (Neuroptera: Chrysopidae podem evitar o forrageamento sobre plantas de Crotalaria juncea (Fabaceae após a emissão de botões florais, quando presas de Utetheisa ornatrix (Lepidoptera: Arctiidae incorporam alcalóides pirrolizidínicos tóxicos dessa planta.

Full Text Available The main objective of this experimental study was to determine how diets containing lupin meal affect the performance indicators, carcass value, and chemical composition of breast and thigh muscles in broiler chickens. The diets tested in experimental groups E1 and E2 differed as follows: in group E1, one third of nitrogen-containing substances (NSs from extracted soybean meal was replaced with NSs from lupin meal; in group E2, two thirds were replaced compared to the control group. The replacement of soybean meal with lupin meal in experimental diets failed to produce any significant effect on the average live weight of chickens on Day 42 of the fattening period compared to the control group. The replacement of soybean meal with lupin meal resulted in decreased average weight of carcass and breast muscles and in decreased yield of breast muscles. Differences between the control group (C and group E2 were significant (P ⪬ 0.01. Chickens in group E2 also showed a significant increase (P ⪬ 0.01 in the yield of the heart and stomach compared to the control group. The differences in weight and yield of thigh muscles between the control group and the experimental groups (E1 and E2 were not significantly affected. As far as chemical composition is concerned, chickens receiving the lupin-containing feed showed a significant (P ⪬ 0.01 increase in the ash content in breast muscles. On the contrary, in thigh muscles in group E2, the ash content decreased significantly (P ⪬ 0.01. The content of calcium showed an increasing trend in both breast and thigh muscles in both experimental groups. In contrast, the content of magnesium in chicken muscles in both experimental groups decreased. These differences were significant (P ⪬ 0.01 only in thigh muscles. Our results show that lupin seed is a suitable substitute for NSs contained in soybean extracted meal. It is considered optimal to replace up to one third of NSs contained in

The strongest infection of leaves was in 2000 (50% and the weakest in 2001 (6,7%. In all the years of the research siliques were rather weak infected (50-8,89%. Besides powdery mildew was found on chinese mustard which injury index ranged from 0,3% in 1999 to 32,3% in 2000. Intensity of diseases was affected generally by the weather conditions. From the seeds of white mustard and chinese mustard were isolated respectively 263 and 137 colonies. Alternaria alternata was the most numerous species which makes respectively 60,9% and 42,3% isolates. Among the fungi pathogenic for white and chinese mustard were also isolated: A. brassicae, Botrytis cinerea and Rhizoctonia solami.

In the present study, three polysaccharide fractions, QSMP-1, QSMP-2, and QSMP-3, were isolated and purified from the seed meal of Chinese quince. These fractions' structures were investigated by high performance anion exchange chromatography (HPAEC), gel permeation chromatography (GPC), Fourier transform infrared (FT-IR), and nuclear magnetic resonance (NMR), and their antioxidant activities were assessed. The results showed that QSMP-1 is a novel polysaccharide with a backbone mainly composed of →4)-Glcp-(1→, →6)-Glcp-(1→, →6)-Galp-(1→, →2, 3, 4)-Xylp-(1→. The side chains consist of →4)-Arap-(1→, →3, 4)-Arap-(1→, →2)-Galp-(1→, →4)-Manp-(1→, →3)-Galp-(1→, and →3, 6)-Glcp-(1→ with the non-reducing terminals Glcp and Galp. QSMP-1 exhibited effective antioxidant activities by ferrous ion chelation and superoxide anion-scavenging in a dose-dependent manner. These investigations of the polysaccharides from the seed meal of Chinese quince provide a scientific basis for the use of the by-products of quince seed oil processing, particularly as an ingredient in functional foods and medicines.

Full Text Available Brassica juncea (Indian mustard is a commercially important oil seed crop, which is highly affected by many biotic stresses. Among them, Alternaria leaf blight and powdery mildew are the most devastating diseases leading to huge yield losses in B. juncea around the world. In this regard, genetic engineering is a promising tool that may possibly allow us to enhance the B. juncea disease resistance against these pathogens. NPR1 (non-expressor of pathogen-related gene 1 is a bonafide receptor of salicylic acid (SA which modulates multiple immune responses in plants especially activation of induced and systemic acquired resistance (SAR. Here, we report the isolation and characterization of new NPR1 homolog (BjNPR1 from B. juncea. The phylogenetic tree constructed based on the deduced sequence of BjNPR1 with homologs from other species revealed that BjNPR1 grouped together with other known NPR1 proteins of Cruciferae family, and was nearest to B. napus. Furthermore, expression analysis showed that BjNPR1 was upregulated after SA treatment and fungal infection but not by jasmonic acid or abscisic acid. To understand the defensive role of this gene, we generated B. juncea transgenic lines overexpressing BjNPR1, and further confirmed by PCR and Southern blotting. The transgenic lines showed no phenotypic abnormalities, and constitutive expression of BjNPR1 activates defense signaling pathways by priming the expression of antifungal PR genes. Moreover, BjNPR1 transgenic lines showed enhanced resistance to Alternaria brassicae and Erysiphe cruciferarum as there was delay in symptoms and reduced disease severity than non-transgenic plants. In addition, the rate of disease spreading to uninfected or distal parts was also delayed in transgenic plants thus suggesting the activation of SAR. Altogether, the present study suggests that BjNPR1 is involved in broad spectrum of disease resistance against fungal pathogens.

Full Text Available Information concerning the response of coffee to organic fertilizers is scarce. This study evaluates the effect of different doses of compost and Crotalaria juncea L. on growth, production and nitrogen nutrition of coffee trees. The treatments consisted of compost at rates of 25, 50, 75 and 100% of the recommended fertilization, with or without the aerial part of C. juncea. C. juncea was grown with NH4-N (2% 15N and applied to coffee. The use of C. juncea increased growth in height and diameter of the coffee canopy. In the first year, the percentage of N derived from C. juncea reached 8.5% at seven months and 4.1% at fifteen months after fertilization. In the second year, the percentage of N derived from C. juncea reached 17.9% N at the early harvest, five months after fertilization. Increased rates of compost increased pH , P , K , Ca , Mg , sum of bases , effective CEC, base saturation and organic matter and reduced potential acidity. 15N allowed the identification of the N contribution from C. juncea with percentage of leaf N derived from Crotalaria juncea from 9.2 to 17.9%.

Full Text Available The present work has been undertaken to study the effect of exogenously application of 24-epiBL and 28-homoBL on soluble protein, proline contents and antioxidant defense system of Brassica juncea L. RLM 619 under the influence of seasonal stress. It was observed that 24-epiBL and 28-homoBL treatment enhance the soluble protein, dry weight and shoot length of B. juncea seedlings under seasonal stress. If seeds treated with the different concentrations (10-6, 10-8 and 10-10 M of 24-epiBL and 28-homoBL revealed batter growth, protein and proline contents as compare to untreated seedlings. Similarly the activities of antioxidant enzymes SOD, CAT, APOX, DHAR, PPO and Auxinases were enhanced by the application of different concentration of both brassinosteroids, whereas MDA content was decrease with both brassinosteroids treatments. Then we have concluded that both brassinolides have the seasonal stress ameliorative properties in B. juncea seedlings grown under the influence of seasonal stress. This study culminates to the role of brassinolides as an anti-stress property for protection of plant from various types of stresses.

When rape oil is chemically extracted, rape seed meal, a solid residue remains. Currently, it is used as animal feed. Several plants for the production of rape methyl ester (RME, biodiesel) are in operation or under construction. Combustion properties have been studied for rape seed meal produced as a by product to rape-methyl esther (RME, biodiesel). Composition of the material has been measured, using proximate and ultimate analysis. The lower heating value was 18.2 +- 0.3 MJ/kg d.w. and the ash content was 7-8 percent d.w. The material is rich in nitrogen and sulphur. Concentrations of K, P, Ca and Mg are high in the fuel. Rape seed meal was mixed with bark and pelletised. Bark pellets were also used as a reference fuel. Pellets with 10 and 30 percent rape seed meal were produced. Material with 80 percent rape seed meal and 20 percent planer shavings was also pelletised. Wood had to be added to provide enough friction in the pelletising process, with adapted equipment rape seed meal could probably be easily pelletised). The material was studied using Thermo-Gravimetric Analysis (TGA), and compared with data from tests with wood powder. The pyrolysis of the rape seed meal has a characteristic temperature of 320 deg C. Devolatilisation starts at 150 deg C (at a lower temperature than for wood powder), and proceeds within a rather wide temperature range. The probable cause is the difference in organic content, in particular protein content. The result does not suggest that the material will be difficult to ignite. Experiments in a bench-scale fluidised bed (5 kW) showed that pellets containing only bark, and the mixture rape seed meal/wood had a bed agglomeration temperature well over the normal operational bed temperature. For the fuel mixtures rape seed meal and bark, the agglomeration temperature was slightly over the operational temperature. Particle emissions from fluidised bed combustion and grate combustion were, the latter simulated using a commercial

Full Text Available The objective of our study was to assess the effect of replacing soybean meal with the meal from whole white lupin seeds (Lupinus albus of the Zulika variety in diets on selected haematological indicators in 40-day-old fattened hybrid mallard ducks. A total of 180 Cherry Valley ducks were divided into three groups (E1, E2, and control. The control group was fed a diet containing soybean meal. Soybean meal replaced with 50% and 100% meal of white lupin seeds were used in group E1 and group E2, respectively. At the end of the fattening, 12 ducks (6 males and 6 females were randomly selected from each group for a haematological examination. From the result of this study, it is clear that the effect of the diet was found only on the slightly varying number of white blood cells and on the proportion of monocytes. Ducks of group E2 showed a slight increase in the total number of leukocytes which was accompanied by a decrease in the percentage share of monocytes (P < 0.05. Based on the results, it can be claimed that the replacement of soybean meal with meal from the Zulika variety of whole white lupin seeds in the diet did not have a negative effect on the determined blood indicators. Therefore, whole white lupin seeds were successfully used as the important protein component of the diet for fattening hybrid mallard ducks.

Separate methods for the analyses of soluble carbohydrates in different plants and simmondsins in jojoba seed meal are described. A reliable gas chromatographic procedure for the simultaneous quantification of D-pinitol, myo-inositoL sucrose, 5-alpha-D-galactopyranosyl-D-pinitol. 2-alpha-D-galactopyranosyl-D-pinitol, simmondsin, 4-demethylsimmondsin, 5-demethylsimmondsin and 4,5-didemethylsimmondsin as trimethylsilyl derivatives in jojoba seed meal has been developed. The study of different extraction mixtures allowed for the quantitative recovery of the 9 analytes by a mixture of methanol-water (80:20, v/v) in the concentration range between 0.1 and 4%. Comparison of the separation parameters on three different capillary stationary phases with MS detection allowed for the choice of the optimal gas chromatographic conditions for baseline separation of the analytes.

The mature jackfruit (Artocarpus heterophyllus) is consumed in Sri Lanka either as a main meal or a meal accompaniment. However, there is no scientific data on the nutrient compositions of cooked jackfruit meals. Thus, the objective of the study was to carry out a nutritional assessment of a composite jackfruit breakfast meal comprising seeds and flesh. A jackfruit meal comprising of flesh (80% available carbohydrate) and seeds (20% available carbohydrate) was included in the study. The study was carried out in a random cross over design. Setting University of Sri Jayewardenepura. Study participants Healthy individuals (n=10, age: 20-30 yrs). The macronutrient contents, rapidly and slowly available glucose (SAG) contents, water solubility index of the jackfruit meal were determined according to standard methods. The GI of the meal was calculated according to FAO/WHO guidelines. The moisture content of the boiled jackfruit flesh was high (82% FW). Jack seeds contained 4.7% protein (FW), 11.1% total dietary fibre (FW) and 8% resistant starch (FW). Jackfruit meal elicited a GI of 75. The Glycaemic Load (GL) of the normal serving size of the meal is medium. The slowly available glucose (SAG) percentage of jackfruit meal (30%) was twice that of the standard. The boiled jackfruit flesh contained disintegrated starch granules while seeds contained intact swollen and disintegrated granules. The jackfruit seeds are a good source of starch (22%) and dietary fibre. The meal is categorized as a low GI meal. The low GI could be dueto the collective contributions from dietary fibre, slowly available glucose and un-gelatinised (intact) starch granules in the seeds.

Transgenic tobacco overexpressing Brassica juncea HMG-CoA synthase 1 shows increased plant growth, pod size and seed yield.

Full Text Available Seeds are very important not only in the life cycle of the plant but they represent food sources for man and animals. We report herein a mutant of 3-hydroxy-3-methylglutaryl-coenzyme A synthase (HMGS, the second enzyme in the mevalonate (MVA pathway that can improve seed yield when overexpressed in a phylogenetically distant species. In Brassica juncea, the characterisation of four isogenes encoding HMGS has been previously reported. Enzyme kinetics on recombinant wild-type (wt and mutant BjHMGS1 had revealed that S359A displayed a 10-fold higher enzyme activity. The overexpression of wt and mutant (S359A BjHMGS1 in Arabidopsis had up-regulated several genes in sterol biosynthesis, increasing sterol content. To quickly assess the effects of BjHMGS1 overexpression in a phylogenetically more distant species beyond the Brassicaceae, wt and mutant (S359A BjHMGS1 were expressed in tobacco (Nicotiana tabacum L. cv. Xanthi of the family Solanaceae. New observations on tobacco OEs not previously reported for Arabidopsis OEs included: (i phenotypic changes in enhanced plant growth, pod size and seed yield (more significant in OE-S359A than OE-wtBjHMGS1 in comparison to vector-transformed tobacco, (ii higher NtSQS expression and sterol content in OE-S359A than OE-wtBjHMGS1 corresponding to greater increase in growth and seed yield, and (iii induction of NtIPPI2 and NtGGPPS2 and downregulation of NtIPPI1, NtGGPPS1, NtGGPPS3 and NtGGPPS4. Resembling Arabidopsis HMGS-OEs, tobacco HMGS-OEs displayed an enhanced expression of NtHMGR1, NtSMT1-2, NtSMT2-1, NtSMT2-2 and NtCYP85A1. Overall, increased growth, pod size and seed yield in tobacco HMGS-OEs were attributed to the up-regulation of native NtHMGR1, NtIPPI2, NtSQS, NtSMT1-2, NtSMT2-1, NtSMT2-2 and NtCYP85A1. Hence, S359A has potential in agriculture not only in improving phytosterol content but also seed yield, which may be desirable in food crops. This work further demonstrates HMGS function in plant

Brassica juncea is an important oil seed crop throughout the world. The demand and cultivation of oil seed crops has gained importance due to rapid increase in world population and industrialization. Fungal diseases pose a great threat to Brassica productivity worldwide. Absence of resistance genes against fungal infection within crossable germplasms of this crop necessitates deployment of genetic engineering approaches to produce transgenic plants with resistance against fungal infections. In the current study, hypocotyls and cotyledons of Brassica juncea, used as explants, were transformed with Agrobacterium tumefacien strain EHA101 harboring binary vector pEKB/NIC containing synthetic chitinase gene (NIC), an antifungal gene under the control of cauliflower mosaic virus promoter (CaMV35S). Bar genes and nptII gene were used as selectable markers. Presence of chitinase gene in trangenic lines was confirmed by PCR and southern blotting analysis. Effect of the extracted proteins from non-transgenic and transgenic lines was observed on the growth of Alternaria brassicicola, a common disease causing pathogen in brassica crop. In comparison to non-transgenic control lines, the leaf tissue extracts of the transgenic lines showed considerable resistance and antifungal activity against A. brassicicola. The antifungal activity in transgenic lines was observed as corresponding to the transgene copy number. (author)

Full Text Available Oilseed crops are being widely evaluated for potential biodiesel production. Seed meal (SM remaining after extracting oil may have use as bioherbicides or organic fertilizers. Brassicaceae SM often contains glucosinolates that hydrolyze into biologically active compounds that may inhibit various pests. Jatropha curcas SM contains curcin, a phytoxin. A 14-day greenhouse study determined that Sinapis alba (white mustard, Brassica juncea (Indian mustard, Camelina sativa, and Jatropha curcas applied to soil at varying application rates [0, 0.5, 1.0, and 2.5% (w/w] and incubation times (1, 7, and 14 d prior to planting affected seed emergence and seedling survival of cotton [Gossypium hirsutum (L.], sorghum [Sorghum bicolor (L. Moench], johnsongrass (Sorghum halepense, and redroot pigweed (Amaranthus retroflexus. With each species, emergence and survival was most decreased by 2.5% SM application applied at 1 and 7 d incubations. White mustard SM incubated for 1 d applied at low and high rates had similar negative effects on johnsongrass seedlings. Redroot pigweed seedling survival was generally most decreased by all 2.5% SM applications. Based on significant effects determined by ANOVA, results suggested that the type, rate, and timing of SM application should be considered before land-applying SMs in cropping systems.

Mutants having desirable agronomic characters were obtained in the high yielding, recommended mustard (B. juncea) varieties Rai 5, RL 9 and Varuna (T 59). Following hybridizations between induced mutants or mutants with other promising varieties, recombinants having superior agronomic traits have been developed. The parent varieties are characterised by open pod arrangement and blackish brown seeds. The mutants and the recombinants have desirable agronomic characters like compact plant type, appressed pods with less shattering nature, yellow seeds, higher oil content and lighter coloured oil. Among the 12 new strains developed at this centre, five have been tested at various locations in the country. At many places, TM-(Trombay Mustard-) cultures outyielded or were at par with the local check varieties. TM-2-11 (Appressed pod mutant) and TM-4 (Yellow bold seeded Mutant) have also been included in the Initial Evaluation Trial of the All India Co-ordinated Research Project in Oilseeds (AICORPO) improvement. Reports so far received from various locations in the country indicate that TM-strains, being relatively early cultures, are suited more for states of Rajasthan, Gujarat, U.P. and Bihar. (author)

The effects and susceptibility of donkeys to Crotalaria juncea and Crotalaria retusa poisoning were determined at high and low doses. Seeds of C. juncea containing 0.074% of dehydropyrrolizidine alkaloids (DHPAs) (isohemijunceines 0.05%, trichodesmine 0.016%, and junceine 0.008%) were administered to three donkeys at 0.3, 0.6 and 1 g/kg body weight (g/kg) daily for 365 days. No clinical signs were observed and, on liver and lung biopsies, the only lesion was a mild liver megalocytosis in the donkeys ingesting 0.6 and 1 g/kg/day. Two other donkeys that received daily doses of 3 and 5 g seed/kg showed initial respiratory signs 70 and 40 days after the start of the administration, respectively. The donkeys were euthanized following severe respiratory signs and the main lung lesions were proliferation of Clara cells and interstitial fibrosis. Three donkeys ingested seeds of C. retusa containing 5.99% of monocrotaline at daily doses of 0.025, 0.05 and 0.1 g/kg for 365 days. No clinical signs were observed and, on liver and lung biopsies, the only lesion was moderate liver megalocytosis in each of the three donkeys. One donkey that received a single dose of 5 g/kg of C. retusa seeds and another that received 1 g/kg daily for 7 days both showed severe clinical signs and died with diffuse centrilobular liver necrosis. No lung lesions were observed. Another donkey that received a single dose of 2.5 g/kg of C. retusa seeds showed no clinical signs. The hepatic and pneumotoxic effects observed are consistent with an etiology involving DHPAs. Furthermore, the occurrence of lung or liver lesions correlates with the type of DHPAs contained in the seeds. Similarly as has been reported for horses, the data herein suggest that in donkeys some DHPAs are metabolized in the liver causing liver disease, whereas others are metabolized in the lung by Clara cells causing lung disease.

Genetic variability was induced, in the 'Kranti' Indian mustard [Brassica/juncea (L.) Czemj. & Cosson]. utilizing 30,40 and 50 kr doses of gamma-ray Irradiation. 'In M 3 generation, compared with the econtrol, substantial decrease was observed in the mean value of various quantitative characters in the mutagen-treated populations. More variation was induced at 30 kr compared with that at 40 or 50 kr dose. Four mutants were identified ar 30 kr dose, which besides being early in maturity, gave better yield also-compared with the control. The better seed yield of the transmutated plants was due either to increase in seed weight or to increase in number of siliquae/plant

Phytase-producing bacteria (PPB) is being investigated as plant growth promoting rhizobacteria (PGPR) to improve the phosphorus (P) nutrition and growth of plants grown in soil with high phytate content. Phytate is dominant organic P forms in many soils and must be hydrolyzed to be available for plants. Indian mustard (Brassica juncea) is a plant with economic importance in agriculture and phytoremediation, therefore biotechnological tools to improve growth and environmental stress tolerance are needed. In this study, we isolated and characterized PPB from Himalayan soils and evaluated their effect on growth and P uptake by B. juncea under greenhouse conditions. Sixty five PPB were isolated and based on phytate hydrolysis, three efficient PPB were chosen and identified as Acromobacter sp. PB-01, Tetrathiobacter sp. PB-03 and Bacillus sp. PB-13. Selected PPB showed ability to grow at wide range of pH, temperature and salt concentrations as well as to harbour diverse PGPR activities, such as: solubilization of insoluble Ca-phosphate (193-642 μg ml(-1)), production of phytohormone indole acetic acid (5-39 μg ml(-1)) and siderophore. Tetrathiobacter sp. PB-03 and Bacillus sp. PB-13 showed 50 and 70 % inhibition of phytopathogen Rhizoctonia solani, respectively. Greenhouse potting assay also showed that the bacterization of B. juncea seeds with Tetrathiobacter sp. PB-03 and Bacillus sp. PB-13 significantly increased the biomass and P content in 30 days old seedlings. This study reveals the potential of PPB as PGPR to improve the growth of B. juncea.

The aim of this study was to determine the effects of soybean meal (SBM) substitution by a mixture of rapeseed meal (RSM), white lupine seeds (WLS) and pea seeds (PS) on productivity, nutrient digestibility, nitrogen retention and gastrointestinal function in Hyplus rabbits. The Control diet (SBM 15 ) contained 15% SBM, whereas Diet SBM 7.5 contained 7.5% SBM, 5% RSM, 4% WLS and 3% PS. In Diet SBM 0, SBM was completely replaced by RSM, WLS and PS (10%, 8% and 6%, respectively). A production trial was performed on 90 Hyplus rabbits aged from 35 to 84 d (45 each sex; 953 ± 4.6 g). A digestion and balance trial was conducted on 30 rabbits. Additionally, several parameters of the gastrointestinal tracts from eight animals from each group were analysed, where special attention was paid to the enzymatic activity of microbiota and the short-chain fatty acids concentration in caecum and colon. The experimental diets did not cause significant differences regarding performance parameters evaluated in vivo and post-mortem, and in the nutrient and energy digestibility or nitrogen retention. The observed changes in the enzymatic activity of large gut microbiota, including the selective increase in secretion of glycoside hydrolases by bacterial cells, seem to be responsible for the unchanged growth performance of rabbits fed diets where SBM was substituted by a mixture of RSM, WLS and PS. The obtained results indicate that in rabbit diets SBM may be, partially or completely, successfully replaced by a feed mixture of RSM, WLS and PS.

Full Text Available This report shows the antioxidant effects of a hemp seed meal protein hydrolysate (HMH in spontaneously hypertensive rats (SHR. Defatted hemp seed meal was hydrolyzed consecutively with pepsin and pancreatin to yield HMH, which was incorporated into rat feed as a source of antioxidant peptides. Young (8-week old SHRs were divided into three groups (8 rats/group and fed diets that contained 0.0%, 0.5% or 1.0% (w/w HMH for eight weeks; half of the rats were sacrificed for blood collection. After a 4-week washout period, the remaining 20-week old SHRs were fed for an additional four weeks and sacrificed for blood collection. Plasma total antioxidant capacity (TAC and superoxide dismutase (SOD, catalase (CAT and total peroxides (TPx levels were determined. Results showed that plasma TAC, CAT and SOD levels decreased in the older 20-week old SHRs when compared to the young SHRs. The presence of HMH in the diets led to significant (p < 0.05 increases in plasma SOD and CAT levels in both young and adult SHR groups; these increases were accompanied by decreases in TPx levels. The results suggest that HMH contained antioxidant peptides that reduced the rate of lipid peroxidation in SHRs with enhanced antioxidant enzyme levels and total antioxidant capacity.

The aim of the present study was to explore the effect of exogenous application of castasterone (CS) on physiologic and biochemical responses in Brassica juncea seedlings under copper (Cu) stress. Seeds were pre-soaked in different concentrations of CS and grown for 7 days under various levels of Cu. The exposure of B. juncea to higher levels of Cu led to decrease of morphologic parameters, with partial recovery of length and fresh weight in the CS pre-treated seedlings. Metal content was high in both roots and shoots under Cu exposure while the CS pre-treatment reduced the metal uptake. Accumulation of hydrogen peroxide (H 2 O 2 ) and superoxide anion radical (O 2 - ) were chosen as stress biomarker and higher levels of H 2 O 2 (88.89%) and O 2 - (62.11%) showed the oxidative stress in metal treated B. juncea seedlings, however, CS pre-treatment reduced ROS accumulation in Cu-exposed seedlings. The Cu exposures lead to enhance the plant's enzymatic and non-enzymatic antioxidant system. It was observed that enzymatic activities of ascorbate peroxidase (APOX), dehydroascorbate reductase (DHAR), and glutathione reductase (GR), glutathione perxoidase (GPOX) and gultrathione-s-transferase increased while activity of monodehydroascorbate reductase (MDHAR) decreased under Cu stress. The pre-treatment with CS positively affected the activities of enzymes. RT-PCR analysis showed that mRNA transcript levels were correlated with total enzymatic activity of DHAR, GR, GST and GSH. Increase in the gene expression of DHAR (1.85 folds), GR (3.24 folds), GST-1 (2.00 folds) and GSH-S (3.18 folds) was noticed with CS pre-treatment. Overall, the present study shows that Cu exposure induced severe oxidative stress in B. juncea plants and exogenous application of CS improved antioxidative defense system by modulating the ascorbate-glutathione cycle and amino acid metabolism.

Brassica juncea var. foliosa (B. juncea var. foliosa) is a promising species for thorium (Th) phytoextraction due to its large biomass, fast growth rate and high tolerance toward Th. To further understand the mechanisms of Th tolerance, the present study investigated the subcellular distribution and chemical forms of Th found in B. juncea var. foliosa Our results indicated that in both roots and leaves, Th contents in different parts of the cells follow the order of cell wall > membranes and soluble fraction > organelles. In particular, Transmission Electron Microscope (TEM) analysis showed that Th was abundantly located in cell walls of the roots. Additionally, when plants were exposed to different concentrations of Th, we have found that Th existed in B. juncea var. foliosa with different chemical forms. Much of the Th extracted by 2% acetic acid (HAc), 1 M NaCl and HCl in roots with the percentage distribution varied from 47.2% to 62.5%, while in leaves, most of the Th was in the form of residue and the subdominant amount of Th was extracted by HCl, followed by 2% HAc. This suggested that Th compartmentation in cytosol and integration with phosphate or proteins in cell wall might be responsible for the tolerance of B. juncea var. foliosa to the stress of Th. - Highlights: • Brassica juncea var. foliosa can adapt to the stress of Th(<200 μM) under hydroponic condition. • Th was selectively distributed on cell wall, membranes and soluble fraction. • Th mainly existed in low-toxicity forms which were benefit for Th tolerance.

Full Text Available Chitinases are the hydrolytic enzymes which belong to the pathogenesis-related (PR protein family and play an important role not only in plant defense but also in various abiotic stresses. However, only a limited number of chitinase genes have been characterised in B. juncea. In this study, we have characterised B. juncea class IV chitinase gene (accession no EF586206 in response to fungal infection, salicylic acid (SA, jasmonic acid (JA treatments and wounding. Gene expression studies revealed that the transcript levels of Bjchitinase (BjChp gene increases significantly both in local and distal tissues after Alternaria infection. Bjchitinase gene was also induced by jasmonic acid and wounding but moderately by salicylic acid. A 2.5 kb class IV chitinase promoter of this gene was isolated from B. juncea by Genome walking (accession no KF055403.1. In-silico analysis of this promoter revealed a number of conserved cis-regulatory elements related to defense, wounding and signalling molecules like SA, and JA. For validation, chitinase promoter was fused to the GUS gene, and the resultant construct was then introduced into Arabidopsis plants. Histochemical analysis of T2 transgenic Arabidopsis plants showed that higher GUS activity in leaves after fungal infection, wounding and JA treatment but weakly by SA. GUS activity was seen in meristematic tissues, young leaves, seeds and siliques. Finally investigation has led to the identification of a pathogen-inducible, developmentally regulated and organ-specific promoter. Present study revealed that Bjchitinase (BjChp promoter is induced during biotic and environmental stress and it can be used in developing finely tuned transgenics.

Selenium is a trace metalloid of global environmental concern. The boundary among its essentiality, deficiency, and toxicity is narrow and mainly depends on the chemical forms and concentrations in which this element occurs. Different plant species-including Brassica juncea-have been shown to play a significant role in Se removal from soil as well as water bodies. Furthermore, the interactions between such plants, showing natural capabilities of metal uptake and their rhizospheric microbial communities, might be exploited to increase both Se scavenging and vegetable biomass production in order to improve the whole phytoextraction efficiency. The aim of the present study was to evaluate the capability of selenite removal of B. juncea grown in hydroponic conditions on artificially spiked effluents. To optimize phytoextraction efficiency, interactions between B. juncea and rhizobacteria were designedly elicited. Firstly, B. juncea was grown on water-filtering agriperlite beds in the presence of three different selenite concentrations, namely, 0.2, 1.0, and 2.0 mM. Plant growth was measured after 3 and 6 weeks of incubation in order to establish the selenite concentration at which the best plant biomass production could be obtained. Afterwards, water-filtering agriperlite beds were inoculated either with a selenium-acclimated microbial community deriving from the rhizosphere of B. juncea grown, erstwhile, in a selenite-amended soil or with axenic cultures of two bacterial strains, vicelike Bacillus mycoides SeITE01 and Stenotrophomonas maltophilia SeITE02, previously isolated and described for their high resistance to selenite. These latter were seeded separately or as a dual consortium. Selenite was amended at a final concentration of 1.0 mM. Total Se content in plant tissues (both shoots and roots), plant biomass production, and persistence of bioaugmented microbial inocula during the experimental time were monitored. Moreover, parameters such as bioconcentration

Full Text Available Application of Brassicaceous seed meal (BSM is a promising biologically based disease-control practice but BSM could directly and indirectly also affect the non-target bacterial communities, including the beneficial populations. Understanding the bacterial response to BSM at the community level is of great significance for directing plant disease management through the manipulation of resident bacterial communities. Fusarium wilt is a devastating disease on pepper. However, little is known about the response of bacterial communities, especially the rhizosphere bacterial community, to BSM application to soil heavily infested with Fusarium wilt pathogen and cropped with peppers. In this study, a 25-day microcosm incubation of a natural Fusarium wilt pathogen-infested soil supplemented with three BSMs, i.e., Camelina sativa ‘Crantz’ (CAME, Brassica juncea ‘Pacific Gold’ (PG, and a mixture of PG and Sinapis alba cv. ‘IdaGold’ (IG (PG+IG, 1:1 ratio, was performed. Then, a further 35-day pot experiment was established with pepper plants growing in the BSM treated soils. The changes in the bacterial community in the soil after 25 days of incubation and changes in the rhizosphere after an additional 35 days of pepper growth were investigated by 454 pyrosequencing technique. The results show that the application of PG and PG+IG reduced the disease index by 100% and 72.8%, respectively, after 35 days of pepper growth, while the application of CAME did not have an evident suppressive effect. All BSM treatments altered the bacterial community structure and decreased the bacterial richness and diversity after 25 days of incubation, although this effect was weakened after an additional 35 days of pepper growth. At the phylum/class and the genus levels, the changes in specific bacterial populations resulting from the PG and PG+IG treatments, especially the significant increase in Actinobacteria-affiliated Streptomyces and an unclassified genus and

Full Text Available The feasibility of carob seed germ meal (CSGM as a soybean meal (SBM replacement in the diet of red tilapia hybrid was evaluated in an 8-week feeding trial. Five isonitrogenous and isocaloric diets with increasing CSGM (0, 10, 20, 30 and 40%, at the expense of SBM, were fed to triplicated groups of tilapia fingerlings. Their growth, feeding efficiency, whole body proximate composition, selected plasma biochemical parameters, and liver and gut histopathology were assessed. The survival and growth of red tilapia were unaffected by the dietary CSGM inclusion up to 30%. Growth and feeding efficiencies were significantly reduced at 40% CSGM inclusion. Hematocrit and body crude lipid were significantly lower (p < 0.05 in fish fed 30–40% CSGM while plasma ALT and protein were significantly higher compared to the control (0% CSGM. In addition, some instances of lipofuscin and cellular degradation were shown in liver while morphological changes were observed in fish fed 30 and 40% CSGM. Some of these included a 60% and 34% reduction in goblet cell prevalence and villi length, respectively, as well as a thickening of the intestinal mucosal and submucosa layers of 51 and 27%, respectively as dietary CSGM increased from 0 to 40%, that was likely due to increased anti-nutritional factors. In conclusion, a dietary inclusion of only up to 20% untreated CSGM was recommended for red hybrid tilapia.

BjuB.CYP79F1 Regulates Synthesis of Propyl Fraction of Aliphatic Glucosinolates in Oilseed Mustard Brassica juncea: Functional Validation through Genetic and Transgenic Approaches.

Full Text Available Among the different types of methionine-derived aliphatic glucosinolates (GS, sinigrin (2-propenyl, the final product in 3C GS biosynthetic pathway is considered very important as it has many pharmacological and therapeutic properties. In Brassica species, the candidate gene regulating synthesis of 3C GS remains ambiguous. Earlier reports of GSL-PRO, an ortholog of Arabidopsis thaliana gene At1g18500 as a probable candidate gene responsible for 3C GS biosynthesis in B. napus and B. oleracea could not be validated in B. juncea through genetic analysis. In this communication, we report the isolation and characterization of the gene CYP79F1, an ortholog of A. thaliana gene At1g16410 that is involved in the first step of core GS biosynthesis. The gene CYP79F1 in B. juncea showed presence-absence polymorphism between lines Varuna that synthesizes sinigrin and Heera virtually free from sinigrin. Using this presence-absence polymorphism, CYP79F1 was mapped to the previously mapped 3C GS QTL region (J16Gsl4 in the LG B4 of B. juncea. In Heera, the gene was observed to be truncated due to an insertion of a ~4.7 kb TE like element leading to the loss of function of the gene. Functional validation of the gene was carried out through both genetic and transgenic approaches. An F2 population segregating only for the gene CYP79F1 and the sinigrin phenotype showed perfect co-segregation. Finally, genetic transformation of a B. juncea line (QTL-NIL J16Gsl4 having high seed GS but lacking sinigrin with the wild type CYP79F1 showed the synthesis of sinigrin validating the role of CYP79F1 in regulating the synthesis of 3C GS in B. juncea.

Full Text Available The objective of this study was to investigate the effect of levels of cottonseed meal with various carbohydrate sources in concentrate on feed intake, nutrient digestibility, rumen fermentation and microbial protein synthesis in dairy bulls. Four, 6 months old dairy bulls were randomly assigned to receive four dietary treatments according to a 2×2 factorial arrangement in a 4×4 Latin square design. Factor A was carbohydrate source; cassava chip (CC and cassava chip+rice bran in the ratio of 3:1 (CR3:1, and factor B was cotton seed meal levels in the concentrate; 109 g CP/kg (LCM and 328 g CP/kg (HCM at similar overall CP levels (490 g CP/kg. Bulls received urea-lime treated rice straw ad libitum and were supplemented with 10 g of concentrate/kg BW. It was found that carbohydrate source and level of cotton seed meal did not have significant effects on ruminal pH, ammonia nitrogen concentration, microbial protein synthesis or feed intake. Animals which received CC showed significantly higher BUN concentration, ruminal propionic acid and butyric acid proportions, while dry matter, organic matter digestibility, populations of total viable bacteria and proteolytic bacteria were lower than those in the CR3:1 treatment. The concentration of total volatile fatty acids was higher in HCM than LCM treatments, while the concentration of butyric acid was higher in LCM than HCM treatments. The population of proteolytic bacteria with the LCM treatments was higher than the HCM treatments; however other bacteria groups were similar among the different levels of cotton seed meal. Bulls which received LCM had higher protein digestibility than those receiving HCM. Therefore, using high levels of cassava chip and cotton seed meal might positively impact on energy and nitrogen balance for the microbial population in the rumen of the young dairy bull.

Two experiments were carried out in Paraná State, Brazil, to evaluate the nutritional value of passion fruit seed meal (PFM) and to study the effect of PFM on growth performance, carcass, and blood characteristics in starter pigs (Topigs 20 × Tybor). In experiment 1, 25 castrated males, averaging 19.1-kg body weight, were individually fed in a completely randomized block design, consisting of five treatments and five replicates and an experimental period that lasted 14 days. In experiment 2, a total of 60 pigs (30 females and 30 castrated males) were distributed in a randomized block design with five treatments, six replications, and two animals per experimental unit and 90 days of experimentation. For both experiments, the same PFM inclusion rates were used in the experimental diets, namely, 0, 4, 8, 12, and 16 %. The metabolizable energy of PFM was estimated to be 15.0 MJ/kg. Inclusion of PFM at any level did not affect average daily gain, daily feed intake, feed/gain ratio, backfat thickness, loin depth, and plasma or blood components. It is concluded that passion fruit seed meal for swine in the starting phase can be added at a rate of up to 16 % in the diet without any negative effects on growth performance, carcass, and blood characteristics in starter commercial line pigs.

A feeding trial was conducted to evaluate the effects of replacing fish meal with rubber seed meal (RSM) on growth, nutrient utilization, and cholesterol metabolism of tilapia (Oreochromis niloticus × Oreochromis aureus). Five experimental diets were formulated with 0, 150, 300, 450, and 600 g kg -1 RSM replacing graded levels of fish meal, respectively. Each diet was randomly assigned to triplicate groups of 25 fish (initial average weight 65.3 g) per aquarium in a rearing system maintained at 29 ± 1 °C for 8 weeks. Dietary 150 g kg -1 RSM inclusion did not affect the weight gain and daily growth coefficient, whereas these were depressed by a further inclusion. Additionally, feed efficiency ratio and protein efficiency ratio were not affected by dietary RSM inclusion regardless of inclusion level. However, the inclusion of 450 and 600 g kg -1 RSM decreased the mid-intestinal trypsin, lipase, and amylase activities; the hepatic acyl-CoA/cholesterol acyl transferase; low-density lipoprotein receptor; and 3-hydroxy-3-methyl-glutaryl-CoA reductase activities. Similarly, dietary 600 g kg -1 RSM inclusion inhibited the plasma catalase and hepatic glutathione peroxidase activities. These results indicated that 150 g kg -1 RSM can be included in tilapia diets, whereas higher inclusion of RSM inhibited the growth rate, digestive enzyme activity, antioxidant capacity, and cholesterol metabolism.

Recent advances in biofuel and bio-oil processing technology require huge supplies of energy feedstocks for processing. Very recently, new carinata seeds have been developed as energy feedstocks for biofuel and bio-oil production. The processing results in a large amount of coproducts, which are carinata meal. To date, there is no systematic study on interactive association between biopolymers and biofunctions in carinata seed as energy feedstocks for biofuel and bioethanol processing and their processing coproducts (carinata meal). Molecular spectroscopy with synchrotron and globar sources is a rapid and noninvasive analytical technique and is able to investigate molecular structure conformation in relation to biopolymer functions and bioavailability. However, to date, these techniques are seldom used in biofuel and bioethanol processing in other research laboratories. This paper aims to provide research progress and updates with molecular spectroscopy on the energy feedstock (carinata seed) and coproducts (carinata meal) from biofuel and bioethanol processing and show how to use these molecular techniques to study the interactive association between biopolymers and biofunctions in the energy feedstocks and their coproducts (carinata meal) from biofuel and bio-oil processing before and after biodegradation.

A field study was conducted in 2008 and 2009 at the USDA, ARS, Plant Genetic Resources Conservation Unit in Griffin, GA, to investigate weed suppression by sunn hemp (Crotalaria juncea L). The objectives were to (1) evaluate the effects of apical meristem removal (AMR) at three dates [5, 6, and 7 wks after planting (WAP) on May 14, 2008 and May 21, 2009] and (2) assess the impact of seeding rates (11, 28, and 45 kg ha(-1)) on weed biomass reduction. Weed species were identified at 4, 8, and 12 wks after sunn hemp planting. Sunn hemp cutting date had no significant effect on weed suppression in 2008 but significant differences for grass weeds at 4, 8, and 12 WAP and for yellow nutsedge at 8 and 12 WAP did occur when compared to the control in 2009. In comparison to the sunn hemp-free control plot in 2009, all three seeding rates had reduced grass weed dry weights at 4, 8, and 12 WAP. The total mass of yellow nutsedge when grown with sunn hemp was reduced compared to the total mass of yellow nutsedge grown in the weedy check for all seeding rates at 8 and 12 WAP. Lower grass weed biomass was observed by 12 WAP for cutting dates and seeding rates during 2008 and 2009. Sunn hemp cutting date and seeding rate reduced branch numbers in both years. The reduction in sunn hemp seeding rates revealed a decrease in weed populations.

We developed an approach to broaden its genetic base within several generations by intensive selection. The Ar subgenome from the Asian oil crop B. rapa (ArAr and the Bc subgenome from the African oil crop B. carinata (BcBcCcCc were combined in a synthesized allohexaploid (ArArBcBcCcCc, which was crossed with traditional B. juncea to generate pentaploid F1 hybrids (ArAjBcBjCc, with subsequent self-pollination to obtain newly synthesized B. juncea (Ar/jAr/jBc/jBc/j. After intensive cytological screening and phenotypic selection of fertility and agronomic traits, a population of new-type B. juncea was obtained and was found to be genetically stable at the F6 generation. The new-type B. juncea possesses good fertility and rich genetic diversity and is distinctly divergent but not isolated from traditional B. juncea, as revealed by population genetic analysis with molecular markers. More than half of its genome was modified, showing exotic introgression and novel variation. In addition to the improvement in some traits of the new-type B. juncea lines, a considerable potential for heterosis was observed in inter-subgenomic hybrids between new-type B. juncea lines and traditional B. juncea accessions. The new-type B. juncea exhibited a stable chromosome number and a novel genome composition through multiple generations, providing insight into how to significantly broaden the genetic base of crops with subgenome introgression from their related species and the potential of exploring inter-subgenomic heterosis for hybrid breeding.

The nutritional value of Brassica seed meals is reduced by the presence of glucosinolates, which are toxic compounds involved in plant defense. Mutation of the genes encoding two glucosinolate transporters (GTRs) eliminated glucosinolates from Arabidopsis thaliana seeds, but translation of loss......-of-function phenotypes into Brassica crops is challenging because Brassica is polyploid. We mutated one of seven and four of 12 GTR orthologs and reduced glucosinolate levels in seeds by 60-70% in two different Brassica species (Brassica rapa and Brassica juncea). Reduction in seed glucosinolates was stably inherited...... over multiple generations and maintained in field trials of two mutant populations at three locations. Successful translation of the gtr loss-of-function phenotype from model plant to two Brassica crops suggests that our transport engineering approach could be broadly applied to reduce seed...

Full Text Available The glucosinolate rich hot and cold hexane extracts of Brassica juncea had a negative effect on the development of Spodoptera litura larvae when they were fed on different concentrations of the extracts. Both larval growth index and pupal growth index declined with treatment. However the hot extract with 3-butenyl isothiocyanate as the predominant compound had a more deleterious effect as at 3125ppm the larvae were unable to complete their development. The nutritional indices too were more adversely affected with hot extract as compared to cold extract. The RGR, RCR, ECI and ECD declined significantly with increase in concentration of the hot hexane extract. The activity of antioxidant enzymes, SOD and catalase decreased while that of phosphatases, GSTs, phenol oxidases increased during the initial treatment duration but decreased on prolonged treatment of the larvae with LC50 concentration of hot extract. A similar trend was observed for glutathione and lipid peroxides but a decrease in ascorbate content was observed as compared to control. The findings reveal a toxic effect of 3-butenylisothiocyanate rich hot hexane extract of B. juncea on S. litura larvae.

It seems that faba bean (FB) seeds could be a good protein-energy component in animal feed, but the presence of anti-nutritional substances limits their use as a substitute of soybean meal. The aim of the study was to examine the influence of different concentrations of raw, low-tannin, FB seeds on the gut-bone axis in Ross 308 broilers. One-day old chickens were randomly subjected to one of the 3 dietary treatments: the control group was fed standard diet based on soybean meal and without FB seeds, and two groups were fed 8%/15% and 16%/22% of raw low-tannin FB seeds in the starter and grower, respectively. On the 35th day, hematological and serum biochemical analyses as well histomorphometry of the small intestine and liver tissue and bone mechanical tests were performed. The diet type had no effect on the body weight gain and feed conversion ratio. However, the basal intestinal structures were significantly reduced in birds fed the lower concentration of FB. The enlargement of nerve plexuses was dependent on the concentration used in the diet and, additionally, on the kind of plexus and location in the intestinal tract. The liver was characterized by an increase in non-hepatocytes. There was no influence of the low-tannin FB seeds on most of the analyzed serum parameters in the 35-day-old broiler chickens, except the decreased concentration of total cholesterol and Ca in both experimental groups, triglycerides in group I, and P and uric acid in group II. Furthermore, the increasing concentration of the dietary low-tannin FB did not influence the activities of AspAT (except the group fed the higher amount of FB), ALAT, and LDH. The broiler chickens had no visible leg lesions and no problem in the locomotor function, but the tibiae were lighter mainly in birds fed the higher concentration of FB seeds. Geometric analysis revealed reduction of the cross section area and wall thickness, indicating a decline in the bone midshaft, which influenced the densitometric

Since gamma irradiation of tomatoes is investigated as a tool for increasing tomato shelf-lefe, in this study the tomato seed oil produced from irradiated tomatoes was compared with that produced from industrial tomato seeds and with cotton seeds. Fatty acid contents of tomato seed oil, produced from industrial tomato seed waste and from tomato seeds (Variety Ace), were found nearly the same as in the edible cotton seed oil. Hence, both tomato seed oils may be considered as an additional source of essential fatty acids especially linoleic. Gamma irradiation doses ranged from 50-200 Krad had no significant effect on total saturated and total unsaturated fatty acids. 200 Krad led to significant increases in lenolic acid on the account of insignificant decrease in palmatic acid. Essentail and non essential amino acids of tomato seed meal seem to be equivalent to these of cotton seed meal. This suggests the possible use of tomato seed meal in animal feeding

Full Text Available The main aim of this experiment was to verify the suitability of two Polish varieties of dehulled lupin seed (the low-protein SONET variety and the high-protein JUNO variety as protein components to replace 50% of soya extract meal in feeding mixtures designed for the feeding of young broilers. The results of this experiment demonstrate that suitable treatment of lupin seed (dehulling may significantly increase its nutritional value. Dehulling provides a product (core in which the level of nitrogen-containing substances is by 27% higher than that in the original seed, providing an important protein component to be added in feeding mixtures for chickens. The experiment has also shown that production performance depends on the particular Lupinus variety used. Chickens fed on the JUNO variety seed (Group E1 reached a live weight of 2.332 kg on Day 40, which is comparable with the control group of chickens (2.337 kg; Group C. However, chickens in Group E2 fed on the SONET variety seed had a conclusively lower average weight (2.280 kg (P Lupinus genus is a major source of the amino acid arginine, which is often deficient in the feeding mixtures.

2008-01-01

The uptake and distribution of Pb sequestered by hydroponically grown (14 days growth) Brassica juncea (3 days exposure; Pb activities 3.2, 32 and 217 μM) was investigated. Lead uptake was restricted largely to root tissue. Examination using scanning transmission electron microscopy-energy dispersive spectroscopy revealed substantial and predominantly intracellular uptake at the root tip. Endocytosis of Pb at the plasma membrane was not observed. A membrane transport protein may therefore be involved. In contrast, endocytosis of Pb into a subset of vacuoles was observed, resulting in the formation of dense Pb aggregates. Sparse and predominantly extracellular uptake occurred at some distance from the root tip. X-ray photoelectron spectroscopy confirmed that the Pb concentration was greater in root tips. Heavy metal rhizofiltration using B. juncea might therefore be improved by breeding plants with profusely branching roots. Uptake enhancement using genetic engineering techniques would benefit from investigation of plasma membrane transport mechanisms. - The sites of Pb sequestration within the root system of hydroponically grown Brassica juncea were identified

Heterosis as investigated in terms of polyploidy and genetic diversity using designed Brassica juncea amphiploid and its progenitor diploid species.

Directory of Open Access Journals (Sweden)

Payal Bansal

Full Text Available Fixed heterosis resulting from favorable interactions between the genes on their homoeologous genomes in an allopolyploid is considered analogous to classical heterosis accruing from interactions between homologous chromosomes in heterozygous plants of a diploid species. It has been hypothesized that fixed heterosis may be one of the causes of low classical heterosis in allopolyploids. We used Indian mustard (Brassica juncea, 2n = 36; AABB as a model system to analyze this hypothesis due to ease of its resynthesis from its diploid progenitors, B. rapa (2n = 20; AA and B. nigra (2n = 16; BB. Both forms of heterosis were investigated in terms of ploidy level, gene action and genetic diversity. To facilitate this, eleven B. juncea genotypes were resynthesized by hybridizing ten near inbred lines of B. rapa and nine of B. nigra. Three half diallel combinations involving resynthesized B. juncea (11×11 and the corresponding progenitor genotypes of B. rapa (10×10 and B. nigra (9×9 were evaluated. Genetic diversity was estimated based on DNA polymorphism generated by SSR primers. Heterosis and genetic diversity in parental diploid species appeared not to predict heterosis and genetic diversity at alloploid level. There was also no association between combining ability, genetic diversity and heterosis across ploidy. Though a large proportion (0.47 of combinations showed positive values, the average fixed heterosis was low for seed yield but high for biomass yield. The genetic diversity was a significant contributor to fixed heterosis for biomass yield, due possibly to adaptive advantage it may confer on de novo alloploids during evolution. Good general/specific combiners at diploid level did not necessarily produce good general/specific combiners at amphiploid level. It was also concluded that polyploidy impacts classical heterosis indirectly due to the negative association between fixed heterosis and classical heterosis.

To distinguish between the radiological and chemical effects of radiocesium, we study the chemical toxicity of cesium in the seedlings of Indian mustard (Brassica juncea L.). In this study, the experiment was designed in two factors and five levels random block design to investigate the interaction effects of Cs and K. Results showed that excessive Cs was one of the main factors influence the growth of Brassica juncea seedlings. And the toxicity of Cs in Brassica juncea is likely to be caused by Cs interacts with K-binding sites in essential K-dependent protein, either competes with K for essential biochemical functions, causing intracellular metabolic disturbance. To test the hypothesis that the toxicity of Cs might cause intracellular metabolic disturbance, next-generation sequencing (NGS)-based Illumina paired-end Solexa sequencing platform was employed to analysis the changes in gene expression, and understand the key genes in B. juncea seedlings responding to the toxicity of Cs. Based on the assembled de novo transcriptome, 2032 DEGs that play significant roles in the response to the toxicity of Cs were identified. Further analysis showed that excessive Cs is disturbance the auxin signal transduction pathway, and inhibited the indoleacetic acid-induced protein (AUX/IAA) genes expression eventually lead the seedlings growth and development be inhibited. The results suggest that disturbances to tryptophan metabolism might be linked to changes in growth. - Highlights: • Analyze the chemical toxicity of cesium in seedlings of Indian mustard. • Distinguish between the radiological and chemical effects of radiocesium. • 2032 DEGs that play significant roles in the response to Cs toxicity were identified. • Excessive Cs is disturbance the auxin signal transduction pathway.

Feeding behaviour of generalist pests on Brassica juncea: implication for manipulation of glucosinolate biosynthesis pathway for enhanced resistance.

Differential accumulation of plant defence metabolites has been suggested to have important ecological consequence in the context of plant-insect interactions. Feeding of generalist pests on Brassica juncea showed a distinct pattern with selective exclusion of leaf margins which are high in glucosinolates. Molecular basis of this differential accumulation of glucosinolates could be explained based on differential expression profile of BjuMYB28 homologues, the major biosynthetic regulators of aliphatic glucosinolates, as evident from quantitative real-time PCR and promoter:GUS fusion studies in allotetraploid B. juncea. Constitutive overexpression of selected BjuMYB28 homologues enhanced accumulation of aliphatic glucosinolates in B. juncea. Performance of two generalist pests, Helicoverpa armigera and Spodoptera litura larvae, on transgenic B. juncea plants were poor compared to wild-type plants in a no-choice experiment. Correlation coefficient analysis suggested that weight gain of H. armigera larvae was negatively correlated with gluconapin (GNA) and glucobrassicanapin (GBN), whereas that of S. litura larvae was negatively correlated with GNA, GBN and sinigrin (SIN). Our study explains the significance and possible molecular basis of differential distribution of glucosinolates in B. juncea leaves and shows the potential of overexpressing BjuMYB28 for enhanced resistance of Brassica crops against the tested generalist pests. © 2017 John Wiley & Sons Ltd.

This study evaluated the nutritional value of 14 canola meals from new varieties of canola and compared them to conventional canola meal samples and soybean meals in chickens. Five experiments that included different sources of canola meals or soybean meals were conducted. For each experiment, a precision-fed rooster assay with conventional or cecectomized roosters was conducted to determine TMEn or amino acid digestibility. Analyzed nutritional composition of the canola meal samples indicated increases in crude protein and amino acids for all test canola meals (49.41 to 50.58% crude protein on a dry matter basis) compared to conventional canola meals (40.73 to 43.01%). All test canola meals also contained lower amounts of neutral detergent fiber and acid detergent fiber. Most test canola meals had significantly higher TMEn values than the conventional canola meals (P nutritional value of the canola meal from new varieties of canola was greater than conventional canola meal for poultry. © 2015 Poultry Science Association Inc.

This work addresses the changes in the phytohormonal signature in the recognition of the necrotrophic fungal pathogen Alternaria brassicicola by susceptible Brassica juncea and resistant Sinapis alba. Although B. juncea, S. alba and Arabidopsis all belong to the same family, Brassicaceae, the phytohormonal response of susceptible B. juncea towards this pathogen is unique because the latter two species express non-host resistance. The differential expression of the PR1 gene and the increased level of salicylic acid (SA) indicated that an SA-mediated biotrophic mode of defence response was triggered in B. juncea upon challenge with the pathogen. Compared to B. juncea, resistant S. alba initiated enhanced abscisic acid (ABA) and jasmonic acid (JA) responses following challenge with this pathogen, as revealed by monitoring the expression of ABA-related genes along with the concentration of ABA and JA. Furthermore, these results were verified by the exogenous application of ABA on B. juncea leaves prior to challenge with A. brassicicola, which resulted in a delayed disease progression, followed by the inhibition of the pathogen-mediated increase in SA response and enhanced JA levels. Therefore, it seems that A. brassicicola is steering the defence response towards a biotrophic mode by mounting an SA response in susceptible B. juncea, whereas the enhanced ABA response of S. alba not only counteracts the SA response but also restores the necrotrophic mode of resistance by enhancing JA biosynthesis.

Chemical composition of seven varieties of sunflower seeds and seed fractions i.e., kernels, hulls and meals was determined. Sunflower meals (SFM) contained 44.00 to 49.52% crude protein, 1.25 to 1.50% fat, 3.43 to 6.75% crude fibre, 7.50 to 8.51% ash, 27.30 to 36.09% nitrogen free extract, 3.12 to 3.51% phytic acid and 2.45 to 3.01% chlorogenic acid. Fatty acid profile of sunflower oil with respect to other vegetable oils (i.e., soybean, mustard, canola, cotton, corn oils) and protein solubility profile of sunflower meal as compared to soybean and mustard meals, indicate that its oil and meal have a great nutritional potential.

Full Text Available African locust bean (Parkia biglobosa seed is rich in protein and has recently found its way into the feed industry. This research was conducted to determine the growth performance, haematological profile and nutrient digestibility by broiler chickens fed diets containing soaked and fermented African locust bean (Parkia biglobosa seed meal (SFALBSM. Five diets were formulated in which SFALSBM was included at graded levels of 0, 7.5, 15, 22.5 and 30% designated as T1, T2, T3, T4 and T5 respectively. Two hundred and twenty five (225 day old broiler chickens (Marshall Strain were fed these diets in a completely randomized design and each treatment was replicated three times with 15 birds per replicate. The experiment lasted 8 weeks (4week starter phase and 4week finisher phase. The results of performance of broiler chicks at starter phase showed there were differences (P0.05 on digestibility of dry matter, crude protein and ash. The crude fibre, ether extract and nitrogen free extract digestibility were affected by treatments (P<0.05. Birds fed T3 had highest crude fibre digestibility value (P<0.05. It was concluded that soaked and fermented African locust bean seed meal can be included in broiler chickens diets up to 15% dietary level at the starter phase and 22.5% at the finisher phase without any adverse effect on performance, haematological profile and nutrient digestibility.

In this study, we examined the potential role of phosphate (P; 0, 50, 100 mg kg -1 ) on growth, gas exchange attributes, and photosynthetic pigments of Brassica napus and Brassica juncea under arsenic (As) stress (0, 25, 50, 75 mg kg -1 ) in a pot experiment. Results revealed that phosphate supplementation (P100) to As-stressed plants significantly increased shoot As concentration, dry biomass yield, and As uptake, in addition to the improved morphological and gas exchange attributes and photosynthetic pigments over P0. However, phosphate-assisted increase in As uptake was substantially (up to two times) greater for B. napus, notably due to higher shoot As concentration and dry biomass yield, compared to B. juncea at the P100 level. While phosphate addition in soil (P100) led to enhanced shoot As concentration in B. juncea, it reduced shoot dry biomass, primarily after 50 and 75 mg kg -1 As treatments. The translocation factor and bioconcentration factor values of B. napus were higher than B. juncea for all As levels in the presence of phosphate. This study demonstrates that phosphate supplementation has a potential to improve As phytoextraction efficiency, predominantly for B. napus, by minimizing As-induced damage to plant growth, as well as by improving the physiological and photosynthetic attributes.

Full text: The inactivation of dominant and co-dominant alleles is becoming increasingly important in changing the composition of seed carbohydrates, protein, oil, fibre and secondary products to suit modern food and feed technologies. In barley, breeding lines adapted to south-eastern Australian conditions have been developed containing a waxy endosperm from the Japanese variety 'Sumire Mochi', the high lysine gene lys from cv. 'Hiproly' of Ethiopia, and the induced high lysine mutant gene lys 3a from 'Risoe 1508'. The improved mutant lines yield 12-34% less than the highest yielding feed barley. The lys and lys 3a alleles suppress the formation of prolamins, the waxy allele inhibits the formation of amylose. It seems difficult to modify the background genotype to fully compensate for the reduction of major storage carbohydrate or protein compounds. However, waxy barleys have uses in some human foods and a premium can be paid to producers. The grain of the provisionally-patented waxy cultivar Wasiro is suitable for pearling. It contains 5% {beta}-glucan (soluble fibre) and therefore should be as effective as oat bran for reducing blood cholesterol. In Indian mustard (Brassica juncea), three cultivars differing in date of maturity, each containing the spontaneous mutant alleles for low erucic acid levels in the seed oil, have been developed to produce a high quality, mildly flavoured cooking/salad oil. The concentration of glucosinolates in the seed meal must be reduced to make it palatable and non-toxic to pigs and poultry. Three B. juncea lines were treated in up to four successive generations with gamma rays or EMS. 60,000 seed samples were analysed in subsequent generations. Two induced mutants with reduced glucosinolate concentrations are now available besides 4 naturally-occurring sources with only little reduced yields. Recombination may give a high-yielding low erucic acid and low glucosinolate variety of B. juncea. (author)

The need of quality protein in the aquaculture sector has forced the incorporation of alternative plant proteins into feeding diets. However, most plant proteins show lower digestibility levels than fish meal proteins, especially in carnivorous fishes. Manipulation of protein content by plant breeding can improve the digestibility rate of plant proteins in fish, but the identification of low digestibility proteins is essential. A reduction of low digestibility proteins will not only increase feed efficiency, but also reduce water pollution. Little is known about specific digestible protein profiles and/or molecular identification of more bioavailable plant proteins in fish diets. In this study, we identified low digestibility L. luteus seed proteins using Atlantic salmon (Salmo salar) crude digestive enzymes in an in vitro assay. Low digestibility proteins were identified by comparing SDS-PAGE banding profiles of digested and non-digested lupin seed proteins. Gel image analysis detected a major 12 kDa protein band in both lupin meal and protein isolate digested products. The 12 kDa was confirmed by 2D-PAGE gels and the extracted protein was analyzed with an ion trap mass spectrometer in tandem mass mode. The MS/MS data showed that the 12 kDa low digestibility protein was a large chain δconglutin, a common seed storage protein of yellow lupin. Comparison of the protein band profiles between lupin meal and protein isolates showed that the isolatation process did not affect the low digestibility of the 12 kDa protein.

Manipulation of protein content by plant breeding can improve the digestibility rate of plant proteins in fish, but the identification of low digestibility proteins is essential. A reduction of low digestibility proteins will not only increase feed efficiency, but also reduce water pollution. Little is known about specific digestible protein profiles and/or molecular identification of more bioavailable plant proteins in fish diets. In this study, we identified low digestibility L. luteus seed proteins using Atlantic salmon (Salmo salar) crude digestive enzymes in an in vitro assay. Low digestibility proteins were identified by comparing SDS-PAGE banding profiles of digested and non-digested lupin seed proteins. Gel image analysis detected a major 12 kDa protein band in both lupin meal and protein isolate digested products. The 12 kDa was confirmed by 2D-PAGE gels and the extracted protein was analyzed with an ion trap mass spectrometer in tandem mass mode. The MS/MS data showed that the 12 kDa low digestibility protein was a large chain δconglutin, a common seed storage protein of yellow lupin. Comparison of the protein band profiles between lupin meal and protein isolates showed that the isolatation process did not affect the low digestibility of the 12 kDa protein. PMID:24278278

Full Text Available The present study was undertaken in order to determine the effect of a dietary of moringa seed cake on digestibility, growth performance, blood chemistry and histopathologic of bocourti’s catfish. Fish were fed with diets formulated by 0, 250, 500, 750, and 1000 g kg-1 of moringa seed cake to replace protein in soybean meal. Fish with mean wet weights of 21.50± 0.25 g per fish were fed experimental diets for 8 weeks. Significant differences (p<0.05 in weight gain, average daily gain and specific growth rate were detected between bocourti’s catfish given the experimental diets. All fish grew normally and no significant difference was observed for survival rate and feed conversion ratio among fish fed tested diets. The highest FCR was generally observed that as moringa seed cake inclusion increased in the diets that were noted to exhibit slightly poor growth performance, feed utilization and pepsin digestibility tested. Blood chemistry and hepatosomatic index did not differ significantly for any of the diet treatments. No histopathological changes were found in distal intestines and liver. The study indicated that the dietary moringa seed cake contains ingredients that could be used for bocourti’s catfish diets possibly not over up to for 500 g kg-1 soybean protein replacement without negative effect on growth, digestibility and histology.

Jatropha curcas, a tropical plant introduced in many Asian and African countries is presently used as a source of biodiesel. The cake after oil extraction is rich in protein and is a potential source of livestock feed. In view of the high toxic nature of whole as well as dehulled seed meal due to the presence of toxic phorbol esters and lectin, the meal was subjected to alkali and heat treatments to deactivate the phorbol ester as well as lectin content. After treatment, the phorbol ester content was reduced up to 89% in whole and dehulled seed meal. Toxicity studies were conducted on male growing rats by feeding treated as well as untreated meal through dietary source. All rats irrespective of treatment had reduced appetite and diet intake was low accompanied by diarrhoea. The rats also exhibited reduced motor activity. The rats fed with treated meals exhibited delayed mortality compared to untreated meal fed rats (p0.02). There were significant changes both in terms of food intake and gain in body weight. Gross examination of vital organs indicated atrophy compared to control casein fed rats. However, histopathological examination of various vital organs did not reveal any treatment related microscopic changes suggesting that the mortality of rats occurred due to lack of food intake, diarrhoea and emaciation. Further studies are in progress for complete detoxification of J. curcas meal for use in livestock feed.

The viability of potato cyst nematode (PCN) populations (Globodera pallida) was evaluated in three field experiments using Brassica juncea, Raphanus sativus and Eruca sativa amendments. These species were summer cultivated and autumn incorporated in experiment 1; in experiment 2, overwintered brassicaceous cover crops were spring incorporated. Experiment 3 involved determination of effects of metconazole application on biomass/glucosinolate production by B. juncea and R. sativus and on PCN pre- and post-incorporation. Glucosinolate contents were determined before incorporation. Following cover crop incorporation, field plots were planted with susceptible potatoes to evaluate the biofumigation effects on PCN reproduction. In experiment 1, PCN population post-potato harvest was reduced (P = 0.03) in B. juncea-treated plots, while R. sativus prevented further multiplication, but in experiment 2 there were no significant effects on PCN reproduction. In experiment 3, B. juncea or R. sativus either untreated or treated with metconazole reduced PCN populations. Glucosinolate concentrations varied significantly between different plant regions and cultivation seasons. Metconazole application increased the sinigrin concentration in B. juncea tissues. Glucosinolate concentrations correlated positively with PCN mortality for summer-cultivated brassicaceous plants. The results demonstrated that B. juncea and R. sativus green manures can play an important role in PCN management, particularly if included in an integrated pest management scheme. © 2014 Society of Chemical Industry.

Remediation of cadmium by Indian mustard (Brassica juncea L. from cadmium contaminated soil: a phytoextraction study

Full Text Available Cadmium is a toxic metal for living organisms and an environmental contaminant. Soils in many parts of the world are slightly too moderately contaminated by Cd due to long term use and disposal of Cd-contaminated wastes. Cost effective technologies are needed to remove cadmium from the contaminated sites. Soil phytoextraction is engineering based, low cost and socially accepted developing technology that uses plants to clean up contaminants in soils. This technology can be adopted as a remediation of cadmium from Cd-contaminated soils with the help of Brassica juncea plant. The objective of this work was to evaluate the cadmium (Cd accumulate and the tolerance of Brassica juncea. The Cd accumulates in all parts of plants (roots, stems and leaves. It was found that accumulating efficiency increased with the increase in the concentration of applied cadmium metal solution. Maximum accumulation of cadmium was found in roots than stem and leaves. Phytoextraction coefficient and translocation factor were highest to show the validity of the Brassica juncea species for hyperaccumulation of the Cd metal. These results suggested that Brassica juncea has a high ability to tolerate and accumulate Cd, so it might be a promising plant to be used for phytoextraction of Cd contaminated soil.

Full Text Available Salinity-imposed limitations on plant growth are manifested through osmotic and ionic imbalances. However, because salinity-induced responses vary considerably among crop plants, monitoring of such responses at an early stage has relevance. In this study, physiological (seed germination, seed vigor index, root length, shoot length, fresh weight, dry weight and biochemical attributes (osmoprotectants, K+/Na+ ratio were analyzed for a time-course assessment of salt responses in Indian mustard (Brassica juncea L. with an emphasis on early monitoring. The results showed strong correlations for total soluble sugars at germination phase (24 h, proline content in the seedling establishment phase (48 h and various physiological parameters including seed vigor index (R2 = 0.901, shoot length (R2 = 0.982, and fresh weight (R2 = 0.980 at 72 h (adaptation under stress. In addition, transcriptional changes were observed under NaCl treatment for key genes belonging to the family of selective ion transporters (NHX, HKT and abscisic acid synthesis (AAO-3. The status of mitochondrial respiration was also examined as a probe for salinity tolerance at an early stage. The results suggested that although all the analyzed parameters showed correlations (negative or positive with salt stress magnitude, their critical response times differed, with most of the studied biochemical, physiological, or molecular markers providing valuable information only after radicle emergence, whereas mitochondrial respiration via alternative oxidase was useful for the early detection of salt responses.

In agricultural fields, heavy metal contamination is responsible for limiting the crop productivity and quality. This study reports that the plants of Brassica juncea L. cv. Pusa bold grown on contaminated substrates [Cu, Cr(VI), As(III), As(V)] under simulated field conditions have shown translocation of metals to the upper part and its sequestration in the leaves without significantly affecting on oil yield, except for Cr and higher concentration of As(V), compared to control. Decrease in the oil content in As(V) treated plants was observed in a dose dependent manner; however, maximum decrease was recorded in Cr treated plants. Among all the metal treatments, Cr was the most toxic as evident from the decrease in oil content, growth parameters and antioxidants. The accumulation of metals was below the detection limit in the seeds grown on 10 and 30 mg kg(-1) As(III) and Cr(VI); 10 mg kg(-1) As(V)) and thus can be recommended only for oil cultivation.

2014-02-01

In this study, the preparative separation and purification of rosmarinic acid (RA) from perilla seed meal (PSM), which is a by-product of edible oil production, was achieved using combined column chromatography over macroporous and polyamide resins. To optimize the RA enrichment process, the performance and separation characteristics of nine selected macroporous resins with different chemical and physical properties were investigated. SP825 resin was the most effective: the content of RA increased from 0.27% in the original extract to 16.58% in the 50% ethanol fraction (a 61.4-fold increase). During further purification treatment on polyamide resin, 90.23% pure RA could be obtained in the 70% ethanol fraction. RA with a higher purity (>95%) could also be easily obtained using one crystallization operation. The proposed method is simple, easily operated, cost-effective, and environmentally friendly and is suitable for both large-scale RA production and waste management. Copyright © 2013 Elsevier B.V.

Large volumes of treated process water are required for protein extraction. Evaporation of this water contributes greatly to the energy consumed in enriching protein products. Thin stillage remaining from ethanol production is available in large volumes and may be suitable for extracting protein rich materials. In this work protein was extracted from ground defatted oriental mustard (Brassica juncea (L.) Czern.) meal using thin stillage. Protein extraction efficiency was studied at pHs between 7.6 and 10.4 and salt concentrations between 3.4 × 10-2 and 1.2 M. The optimum extraction efficiency was pH 10.0 and 1.0 M NaCl. Napin and cruciferin were the most prevalent proteins in the isolate. The isolate exhibited high in vitro digestibility (74.9 ± 0.80%) and lysine content (5.2 ± 0.2 g/100 g of protein). No differences in the efficiency of extraction, SDS-PAGE profile, digestibility, lysine availability, or amino acid composition were observed between protein extracted with thin stillage and that extracted with NaCl solution. The use of thin stillage, in lieu of water, for protein extraction would decrease the energy requirements and waste disposal costs of the protein isolation and biofuel production processes.

Rape seed glucosinolate: radiation inactivation and physiological performance of broiler fed irradiated rapeseed meal

International Nuclear Information System (INIS)

Farag, M.Diaa El-Din H.

1994-01-01

Rape seeds meal (RSM) is a high quality protein supplement suitable for all classes of livestock. The major area of concern in animal nutrition has been glucosinolates and their derivative products which cause depressed performance in poultry or may be even toxic. Therefore, these substances must be removed or inactivated before the meal can be used as potential protein source for food or feed. I the current study, RSM has been used to test whether gamma radiation processing can inactivate glucosinolates as a step towards detoxication. Samples were exposed to gamma rays of 10, 50, 100 and 250 kGy. Approximated analysis showed that RSM was not affected by irradiation processing up to 250 kGy. However, the crude fiber content decreased at the highest dose while at doses of 10, 50 100 and 250 kGy the available lysine decreased by 6.76%, 9.46%, 17.84% and 22.43%, respectively. Radiation processing at 250 kGy significantly inactivated glucosinolate by 85% from its initial value. In a 8-week chick-feeding study, raw and irradiated RSM were applied at 30%. The diets containing raw and irradiated (at 10, 50 and 100 kGy) RSM had somewhat low growth and thyroid, liver and kidney enlargement compared to the basal control group. No significant difference was observed between chicks fed on RSM irradiated at 250 kGy and those fed on basal diet. No significant differences were observed in the serum protein, albumin, GPT, uric acid, creatine and basal diet groups. Those kept on raw and irradiated at 10, 50 and 100 kGy RSM had higher GOT than those kept on irradiated at 250 kGy RSM and basal diet. Radiation treatment of RSM up to 250 kGy improved its nutritional quality by decreasing the glucosinolate and consequently maintained the chicks in a better health condition. (author)

The industrial expansion, smelting, mining and agricultural practices have increased the release of toxic trace elements (TEs) in the environment and threaten living organisms. The microbe-assisted phytoremediation is environmentally safe and provide an effective approach to remediate TEs contaminated soils. A pot experiment was conducted to test the potential of an Actinomycete, subspecies Streptomyces pactum (Act12) along with medical stone compost (MSC) by growing Brassica juncea in smelter and mines polluted soils of Feng County (FC) and Tongguan (TG, China), respectively. Results showed that Zn (7, 28%), Pb (54, 21%), Cd (16, 17%) and Cu (8, 10%) uptake in shoot and root of Brassica juncea was pronounced in FC soil. Meanwhile, the Zn (40, 14%) and Pb (82, 15%) uptake in the shoot and root were also increased in TG soil. Shoot Cd uptake remained below detection, while Cu decreased by 52% in TG soil. The Cd and Cu root uptake were increased by 17% and 33%, respectively. Results showed that TEs uptake in shoot increased with increasing Act12 dose. Shoot/root dry biomass, chlorophyll and carotenoid content in Brassica juncea were significantly influenced by the application of Act12 in FC and TG soil. The antioxidant enzymatic activities (POD, PAL, PPO and CAT) in Brassica juncea implicated enhancement in the plant defense mechanism against the TEs induced stress in contaminated soils. The extraction potential of Brasssica was further evaluated by TF (translocation factor) and MEA (metal extraction amount). Based on our findings, further investigation of Act12 assisted phytoremediation of TEs in the smelter and mines polluted soil and hyperaccumulator species are suggested for future studies.

2015-01-01

Chemical composition is critical information for product quality and exploration of new use. Hence defatted cottonseed meals from both glanded (with gossypol) and glandless (without gossypol) cotton seeds were separated into water soluble and insoluble fractions, or water soluble, alkali soluble as well as total protein isolates. The contents of gossypol, total protein and amino acids, fiber and carbohydrates, and selected macro and trace elements in these products were determined and compared with each other and with those of soy meal products. Data reported in this work improved our understanding on the chemical composition of different cottonseed meal products that is helpful for more economical utilization of these products. These data would also provide a basic reference for product standards and quality control when the production of the cottonseed meal products comes to pilot and industrial scales. PMID:26079931

Significant differences (p<0.05 were detected in performance, carcass weight, weight and breast yield, and leg weight. The best results were obtained with 33 and 66 g/kg as compared to the control diet and 100 g SSM /kg. Abdominal fat decreased with the inclusion of 66 and 100 g SSM / kg, but the sensory quality of breast and thighs was not affected by the inclusion of SSM. The serum levels of total cholesterol, very low density (VLDL and low density (LDL lipoproteins, triglycerides, glucose and atherogenic index decreased with the inclusion of 100 g/kg of SSM, except for high density lipoproteins (HDL, which increased. The inclusion of 0, 33, 66 and 100 g/kg of SSM in broiler diets, partially replacing soybean meal and vegetable oil, improved live performance and edible portions yield. In addition, abdominal fat and serum levels of harmful lipids were reduced, whereas serum levels of beneficial lipids increased. There was no effect on meat sensory quality.

Processing scale-up of sicklepod (Senna obtusifolia L.) seed.

Harry-O'Kuru, Rogers E; Mohamed, Abdellatif

2009-04-08

Sicklepod (Senna obtusifolia L.) is an invasive weed species especially of soybean and other field crops in the southeastern United States. The seeds contain a small amount (5-7%) of a highly colored fat as well as various phenolics, proteins, and galactomannans. The color of sicklepod seed oil is such that the presence of a small amount of the weed seed in a soybean crush lowers the quality of the soybean oil. Sicklepod is very prolific, and even volunteer stands yield >1000 lb of seed per acre, and prudence calls for tapping the potential of this weed as an alternative economic crop in the affected region. Pursuant to this, we have shown in laboratory-scale work the feasibility of separating the components of sicklepod seed. However, at kilogram and higher processing quantities, difficulties arise leading to modification of the earlier approach in order to efficiently separate components of the defatted seed meal. In a version for cleanly separating the proteins, the defatted meal was extracted with 0.5 M NaCl solution to remove globular proteins. Prolamins were extracted from the pellet left after salt extraction using 80% ethanol, and glutelins were then obtained in 0.1 N alkali from the residual solids left from ethanol treatment. In a pilot-scale version for water-soluble polysaccharides, the defatted meal was stirred with deionized water (DI) and centrifuged. The pooled centrifugates were heated to 92 degrees C (20-25 min), filtered, cooled to room temperature, and passed through a column of Amberlite XAD-4 to separate the polysaccharides from the anthraquinones. Senna obtusifolia L. is a one-stop-shop of a seed (from food components to medicinals).

Fourty-eight broiler chicks (day-old) were used in a 4 weeks feeding experiment to assess the growth response and the performance of broiler chicks fed raw Leucaena leucociphala seed meal (RLSM), roasted L. leucociphala seed meal (RoLSM) and steamed L. leucociphala seed meal (SLSM). The L. leucociphala seed, which serve as a source of protein were subjected to two treatments (roasting and steaming). Soybean based diet served as the control. There were four (4) experimental groups, each made up of four birds in three replicates allocated to the experimental diets. The results showed that the average final live weight, average weekly weight gain and average feed intake of birds fed with RoLSM performed better than birds fed with RLSM and SLSM. It was observed that the percentage organ to body weight of birds fed with the processed LSM were significantly (P < 0.05), higher as compared to the RLSM. A significant (P < 0.05) increase in the activity of aspartate transferase in the organs (heart, kidney and liver) of broilers fed with RoLSM was observed as compared to those fed with RLSM. The results showed a significant (P < 0.05), reduction in the activity of alanine transferase of organs of broilers chicks fed with processed L. leucociphala compared to the control. It is therefore, concluded that the processing techniques applied were able to improve the nutritional quality of L. leucociphala seed meal but relatively lower to the soybean based meal. (author)

The complete sequence of the mitochondrial genome was determined for two cultivars of Brassica rapa . After determining the sequence of a Chinese cabbage variety, 'Oushou hakusai', the sequence of a mizuna variety, 'Chusei shiroguki sensuji kyomizuna', was mapped against the sequence of Chinese cabbage. The precise sequences where the two varieties demonstrated variation were ascertained by direct sequencing. It was found that the mitochondrial genomes of the two varieties are identical over 219,775 bp, with a single nucleotide polymorphism (SNP) between the genomes. Because B. rapa is the maternal species of an amphidiploid crop species, Brassica juncea , the distribution of the SNP was observed both in B. rapa and B. juncea . While the mizuna type SNP was restricted mainly to cultivars of mizuna (japonica group) in B. rapa , the mizuna type was widely distributed in B. juncea . The finding that the two Brassica species have these SNP types in common suggests that the nucleotide substitution occurred in wild B. rapa before both mitotypes were domesticated. It was further inferred that the interspecific hybridization between B. rapa and B. nigra took place twice and resulted in the two mitotypes of cultivated B. juncea .

Full text: Marc is the leftover material (skins, pulp, seeds, stems) from the fermentation mainly of red wines. Owing to the increase in Australian wine production for home and export, and the decrease in Spirits consumption, marc could be in surfeit- Marc seeds for example, still contain oil and tannins which are useful products. So the titular study by EPR was undertaken. Grapeseeds of various varieties were collected on the vine, and from marc after fermentation. The meal remaining from marc seeds after oil extraction was also collected, and climate was taken into account. From this very limited trial, there appears to be no obvious effect of climate on phenolic content. In most cases, the phenolic content of grapeseeds post-winemaking is lower than that pre-winemaking, consistent with the winemaking process significantly affecting phenolic content. For grapeseed meal, in most cases the phenolic content is lower than that of the seeds used to produce the meal. This 'negative' effect of the oil extraction process is consistent with our previously unpublished work (commercial - in - confidence), but is not necessarily economically significant

In a population of sunn hemp (C. juncea), irradiated with gamma rays (30 Kr), a single plant was found to exhibit the presence of two ring univalents in 75.5% pollen mother cells. This was interpreted as a result of an interchange between the opposite arms of two homologous chromosomes giving rise to pseudoisochromosomes. In few other cells, four univalents and a single quadrivalent were also observed, thus indicating that two other interchanges involved very small segments, one of them between homologous chromosomes and the other between non-homologous chromosomes.

Rising sea levels threaten coastal safety by increasing the risk of flooding. Coastal dunes provide a natural form of coastal protection. Understanding drivers that constrain early development of dunes is necessary to assess whether dune development may keep pace with sea-level rise. In this study, we explored to what extent salt stress experienced by dune building plant species constrains their spatial distribution at the Dutch sandy coast. We conducted a field transplantation experiment and a glasshouse experiment with two dune building grasses Ammophila arenaria and Elytrigia juncea . In the field, we measured salinity and monitored growth of transplanted grasses in four vegetation zones: (I) nonvegetated beach, (II) E. juncea occurring, (III) both species co-occurring, and (IV) A. arenaria dominant. In the glasshouse, we subjected the two species to six soil salinity treatments, with and without salt spray. We monitored biomass, photosynthesis, leaf sodium, and nutrient concentrations over a growing season. The vegetation zones were weakly associated with summer soil salinity; zone I and II were significantly more saline than zones III and IV. Ammophila arenaria performed equally (zone II) or better (zones III, IV) than E. juncea , suggesting soil salinity did not limit species performance. Both species showed severe winter mortality. In the glasshouse, A. arenaria biomass decreased linearly with soil salinity, presumably as a result of osmotic stress. Elytrigia juncea showed a nonlinear response to soil salinity with an optimum at 0.75% soil salinity. Our findings suggest that soil salinity stress either takes place in winter, or that development of vegetated dunes is less sensitive to soil salinity than hitherto expected.

A study was conducted on a sandy clay loam soil at the National Agricultural Research Centre, Islamabad, Pakistan, during 2005 and 2006. The mustard (Brassica juncea) variety BARD-1 was treated with various levels of Zn and Fe, (0-0, 0-1.5, 0-3, 2.5-0, 2.5-1.5, 2.5-3, 5-0, 5-1.5 kgha/sup -1/ and 5-3 kgha/sup -1/, respectively. A basal dose of 90N and 60P kgha/sup -1/ was applied, in the form of Urea and triple super phosphate (TSP) with Zn and Fe. The increase in Zn and Fe fertility from 0-1.5 to 5-1.5 kg ha/sup -1/ increased yield of BARD-I. The maximum yield response was recorded when 5 kg ha/sup -1/ Zn and 1.5 kg ha/sup -1/ Fe were applied. Beyond this level, no further increase in yield was recorded in any mustard traits. A positive correlation was recorded between seed yield and 1000-seed weight with the application of 5 kg Zn ha-1 and 1.5 kg Fe ha/sup -1/ in combination at the time of sowing. It can therefore be concluded that 100 % seed yield of mustard variety BARD-l increased at 5 Zn: 1.5 Fc kg ha-1 as a result of increased pods plant/sup -l/, number of seeds pod-1 and 1000-seed weight.

Full Text Available The objective of this trial was to evaluate the effect of sunflower seed inclusion (0, 1.4, 2.8, 4.2 and 5.6% in a laying hen diet containing corn, soybean meal, wheat meal and soybean oil as main ingredients on performance and egg quality. The evaluated variables were daily feed intake, average egg weight, feed conversion (kg.kg-1 and kg.dz-1, eggshell percentage, yolk color and Haugh unit. One hundred and sixty 25 week-old Lohmann laying hens were used in a completely randomized design with five treatments and four replications of eight birds per experimental unit. Four periods of 28 days were evaluated during 112 days. The inclusion of sunflower seed in the diet had no effect on production parameters during the experimental period. Thus, can be concluded that sunflower seed might be used at concentrations up to 5.6% in laying hen diets without affecting performance and egg quality.

One hundred twenty pigs were used to determine effects of graded levels of microbial phytase on the apparent total tract digestibility (ATTD) of P and Ca and the standardized total tract digestibility (STTD) of P in 4 sources of canola meal and in 1 source of soybean meal (SBM) fed to growing pigs. The 4 sources of canola meal were produced from 1 source of high-protein canola seeds and 2 sources of conventional canola seeds with 1 of the conventional canola seeds being divided into 2 separate batches before crushing. Pigs (16.2 ± 5.3 kg initial BW) were individually housed in metabolism crates and were randomly allotted to 1 of 20 diets in a 5 × 4 factorial arrangement of treatments with 5 ingredients and 4 levels of phytase. There were 6 replicate pigs per diet. Five basal diets based on high-protein canola meal (CM-HP), high-temperature processed canola meal (CM-HT), low-temperature processed canola meal (CM-LT), conventional canola meal (CM-CV), or SBM were formulated. The basal diets contained no phytase. Fifteen additional diets were prepared by adding approximately 500, 1,500, or 2,500 phytase units/kg to each of the 5 basal diets. Feces were quantitatively collected for 5 d based on the marker-to-marker approach after a 7-d adaptation period. Results indicated that supplementation of microbial phytase increased (linear, phytase also increased (linear and quadratic, phytase was added, but no differences were observed in the ATTD and STTD of P in SBM, CM-HP, CM-HT, or CM-CV if the highest amount of phytase were added (interaction, phytase on the STTD of P in CM-HP, CM-HT, CM-LT, CM-CV, and SBM. In conclusion, inclusion of graded levels of microbial phytase increased the ATTD and STTD of P in CM-HP, CM-HT, CM-LT, CM-CV, and SBM and the response to microbial phytase added to each ingredient can be predicted by regression equations.

People in developing countries depend largely on non-conventional protein sources to augment the availability of proteins in their diets. Watermelon seed meal is reported to contain an adequate amount of nutritional proteins that could be extracted for use as nutritional ingredients in food products. Osborne classification showed that globulin was the major protein (≥500 g kg (-1)) present in watermelon seed meal, followed by albumin and glutelin. Sodium dodecyl sulfate polyacrylamide gel electrophoresis indicated that the polypeptides had low molecular weights ranging from 35 to 47 kDa. Isoelectric focusing revealed that the isoelectric point of most proteins was in the acidic range 4-6. These proteins are rich in aspartic acid, glutamic acid and serine. An increase in pH (5-9) significantly (P watermelon protein fractions respectively, while surface hydrophobicity ranged from 126.4 to 173.2 and from 125.8 to 169.3 respectively. The foaming and emulsifying properties of albumin were better than those of the other proteins studied. The good nutritional and functional properties of watermelon seed meal proteins suggest their potential use in food formulations. Copyright © 2010 Society of Chemical Industry.

Full Text Available Abstract Background Allyl isothiocyanate (AITC from mustard is cytotoxic; however the mechanism of its toxicity is unknown. We examined the effects of AITC on heat shock protein (HSP 70 expression in Caenorhabditis elegans. We also examined factors affecting the production of AITC from its precursor, sinigrin, a glucosinolate, in ground Brassica juncea cv. Vulcan seed as mustard has some potential as a biopesticide. Findings An assay to determine the concentration of AITC in ground mustard seed was improved to allow the measurement of AITC release in the first minutes after exposure of ground mustard seed to water. Using this assay, we determined that temperatures above 67°C decreased sinigrin conversion to AITC in hydrated ground B. juncea seed. A pH near 6.0 was found to be necessary for AITC release. RT-qPCR revealed no significant change in HSP70A mRNA expression at low concentrations of AITC ( 1.0 μM resulted in a four- to five-fold increase in expression. A HSP70 ELISA showed that AITC toxicity in C. elegans was ameliorated by the presence of ground seed from low sinigrin B. juncea cv. Arrid. Conclusions • AITC induced toxicity in C. elegans, as measured by HSP70 expression. • Conditions required for the conversion of sinigrin to AITC in ground B. juncea seed were determined. • The use of C. elegans as a bioassay to test AITC or mustard biopesticide efficacy is discussed.

Legume seed proteins have to be chemically characterized in order to properly link their nutritional effects with their chemical structure. Vicilin and albumin fractions devoid of cross-contamination, as assessed by mass peptide fingerprinting analysis, were obtained from defatted pea (Pisum sativum cv. Bilbo) meal. The extracted protein fractions contained 56.7-67.7 g non-starch polysaccharides kg⁻¹. The vicilin fraction was higher than legumins in arginine, isoleucine, leucine, phenylalanine and lysine. The most abundant amino acids in the albumin fraction were aspartic acid, glutamic acid, lysine and arginine, and the amounts of methionine were more than double than those in legumins and vicilins. The pea albumin fraction showed a clear enrichment of protease inhibitory activity when compared with the seed meal. In vitro digestibility values for pea proteins were 0.63 ±  0.04, 0.88 ±  0.04 and 0.41 ±  0.23 for legumins, vicilins and albumins respectively. Vicilin and albumin fractions devoid of cross-contamination with other proteins were obtained from pea seed meal. The vicilin fraction also contained low amounts of soluble non-starch polysaccharides and was enriched in isoleucine, leucine, phenylalanine and lysine. In vitro digestibility values for pea proteins were similar or even numerically higher than those for control proteins. © 2013 Society of Chemical Industry.

Hairy root cultures of Brassica juncea and Chenopodium amaranticolor were developed by genetic transformation using Agrobacterium rhizogenes. The stable, transformed root systems demonstrated a high growth rate of 1.5-3. g/g dry weight/day in Murashige and Skoog medium. In the present study, hairy root system was used for removal of uranium from the solution of concentration up to 5000 μM. The results indicated that the hairy roots could remove uranium from the aqueous solution within a short period of incubation. B. juncea could take up 20-23% of uranium from the solution containing up to 5000 μM, when calculated on g/g dry weight basis. C. amaranticolor showed a slow and steady trend in taking up uranium, with 13 uptake from the solution of 5000 μM concentration. Root growth was not affected up to 500 μM of uranium nitrate over a period of 10 days

The objective of the current study was to evaluate the effects of feeding increasing levels of velvet bean seed meal (VBM; 0, 12, 24, and 36 %) on the performance of Mashona doelings. Dry matter intake was lower (P < 0.05) for the control diet compared to VBM diets, but linearly declined (P < 0.05) with increasing levels of VBM. Average daily weight gain was significantly different between experimental groups. Doelings' final live weights and average daily gains were slightly higher in control group than other three supplemented groups where they linearly declined (P < 0.05) with increasing levels of VBM. The cost per kilogram of feed, however, decreased with high inclusion level of VBM. Result suggested that high inclusion level of VBM negatively influenced the growth of young goats probably due to the presence of some anti-nutritional factors which needs further investigation.

Genetic improvement of soybean protein meal is a complex process because of negative correlation with oil, yield, and temperature. This review describes the progress in mapping and genomics, identifies knowledge gaps, and highlights the need of integrated approaches. Meal protein derived from soybean [Glycine max (L) Merr.] seed is the primary source of protein in poultry and livestock feed. Protein is a key factor that determines the nutritional and economical value of soybean. Genetic improvement of soybean seed protein content is highly desirable, and major quantitative trait loci (QTL) for soybean protein have been detected and repeatedly mapped on chromosomes (Chr.) 20 (LG-I), and 15 (LG-E). However, practical breeding progress is challenging because of seed protein content's negative genetic correlation with seed yield, other seed components such as oil and sucrose, and interaction with environmental effects such as temperature during seed development. In this review, we discuss rate-limiting factors related to soybean protein content and nutritional quality, and potential control factors regulating seed storage protein. In addition, we describe advances in next-generation sequencing technologies for precise detection of natural variants and their integration with conventional and high-throughput genotyping technologies. A syntenic analysis of QTL on Chr. 15 and 20 was performed. Finally, we discuss comprehensive approaches for integrating protein and amino acid QTL, genome-wide association studies, whole-genome resequencing, and transcriptome data to accelerate identification of genomic hot spots for allele introgression and soybean meal protein improvement.

Mustard clubroot, caused by Plasmodiophora brassicae, is a serious disease that affects Brassica juncea var. tumida Tsen, a mustard plant that is the raw material for a traditional fermented food manufactured in Chongqing, China. In our laboratory, we screened the antagonistic bacteria Zhihengliuella aestuarii against P. brassicae. To better understand the biocontrol mechanism, three transcriptome analyses of B. juncea var. tumida Tsen were conducted using Illumina HiSeq 4000, one from B. juncea only inoculated with P. brassicae (P), one inoculated with P. brassica and the biocontrol agent Z. aestuarii at the same time (P + B), and the other was the control (H), in which P. brassicae was replaced by sterile water. A total of 19.94 Gb was generated by Illumina HiSeq sequencing. The sequence data were de novo assembled, and 107,617 unigenes were obtained. In total, 5629 differentially expressed genes between biocontrol-treated (P + B) and infected (P) samples were assigned to 126 KEGG pathways. Using multiple testing corrections, 20 pathways were significantly enriched with Qvalue ≤ 0.05. The resistance-related genes, involved in the production of pathogenesis-related proteins, pathogen-associated molecular pattern-triggered immunity, and effector-triggered immunity signaling pathways, calcium influx, salicylic acid pathway, reactive oxygen intermediates, and mitogen-activated protein kinase cascades, and cell wall modification, were obtained. The various defense responses induced by the biocontrol strain combatted the P. brassicae infection. The genes and pathways involved in plant resistance were induced by a biocontrol strain. The transcriptome data explained the molecular mechanism of the potential biocontrol strain against P. brassicae. The data will also serve as an important public information platform to study B. juncea var. tumida Tsen and will be useful for breeding mustard plants resistant to P. brassicae.

Jojoba (Simmondsia chinensis) is a perennial plant with an interesting economic value by processing it for liquid wax production. By pressing of jojoba seeds, by-product which has been called "residual meal" has been obtained, and because of its high protein content, it would be a great interest to evaluate it as animal feedstuff. The results of this study showed the following. Both seed and residual meal were analyzed in regard to their chemical proximal composition: crude protein 14.03 and 25.24%; ether extract, 48.89 and 14.73%; crude fiber, 10.03 and 10.07%; ash, 1.59 and 4.72, and nitrogen-free extract, 25.46 and 45.25, the limiting amino acids being methionine, lysine and isoleucine. The trypsin inhibitor factors were 13.747 and 11,197 TIU/g; and hemagglutinins and saponins were negative for both samples. Cyanogenic glucosides were positive in both samples. It was concluded that jojoba residual meal is an alternative as an adequate feedstuff in those regions where jojoba is produced. Nevertheless, prior to consumption it must be treated so as to eliminate the toxic factors.

The role of relative humidity (RH) while processing and storing seeds of Brassica spp. and Eruca sativa was investigated by creating different levels of relative humidity, namely, 75%, 50%, 32%, and 11% using different saturated salt solutions and 1% RH using concentrated sulphuric acid. The variability in seed storage behaviour of different species of Brassica was also evaluated. The samples were stored at 40 ± 2°C in sealed containers and various physiological parameters were assessed at different intervals up to three months. The seed viability and seedling vigour parameters were considerably reduced in all accessions at high relative humidity irrespective of the species. Storage at intermediate relative humidities caused minimal decline in viability. All the accessions performed better at relative humidity level of 32% maintaining seed moisture content of 3%. On analyzing the variability in storage behaviour, B. rapa and B. juncea were better performers than B. napus and Eruca sativa.

This study was designed to assess the effects of partial substitution of roasted soybean seed with sweet potato (Ipomoea batatas) leaf meal (SPLM) on growth performances and carcass components of broiler chickens. The experiment was a completely randomized design consisting of five dietary treatments replicated four times with ten chicks each. The control diet (treatment 1, T1) contained roasted soybean seed as the major protein source without SPLM and treatment diets containing SPLM at the levels of 30 g/kg (treatment 2, T2), 60 g/kg (treatment 3, T3), 90 g/kg (treatment 4, T4) and 120 g/kg (treatment 5, T5) by partially substituting the roasted soybean seed in the control diet. The results indicated that the body weight gain in chickens reared in T1 was (pchickens reared in T1 was (pchickens fed on T1 was (pChickens fed with T2 diet had numerically higher values of slaughter, dressed carcass and breast than those reared in T4 and T5 diets. It can be concluded that the partial substitution of roasted soybean seed with sweet potato leaf might be economically feasible feeding strategy of broiler chickens in smallholder poultry farm settings.

A digestibility trial was conducted to assess the effect of dehulling, steam-cooking and microwave-irradiation on the apparent digestibility of nutrients in white lupin (Lupinus albus) seed meal when fed to rainbow trout (Oncorhynchus mykiss) and Atlantic salmon (Salmo salar). Six ingredients, whole lupin seed meal (LSM), dehulled LSM, dehulled LSM steam-cooked for 15 or 45 min (SC15 and SC45, respectively) and LSM microwave-irradiated at 375 or 750 W (MW375 and MW750, respectively), were evaluated for digestibility of dry matter, crude protein (CP), lipids, nitrogen-free extractives (NFE) and gross energy (GE). The diet-substitution approach was used (70% reference diet + 30% test ingredient). Faeces from each tank were collected using a settlement column. Dehulled LSM showed higher levels of proximate components (except for NFE and crude fibre), GE and phosphorus in comparison to whole LSM. Furthermore, SC15, SC45, MW375 and MW750 showed slight variations of chemical composition in comparison to dehulled LSM. Results from the digestibility trial indicated that dehulled LSM, SC15, SC45 and MW375 are suitable processing methods for the improvement of nutrients' apparent digestibility coefficient (ADC) in whole LSM. MW750 showed a lower ADC of nutrients (except for CP and lipids for rainbow trout) in comparison with MW350 for rainbow trout and Atlantic salmon, suggesting a heat damage of the ingredient when microwave-irradiation exceeded 350 W.

The aim of this study was to valorize orange (Citrus sinensis) seeds, which are generated as waste. This study presents data about raw orange seed, the meal gained after cold pressing, and characterization data of the cold pressed seed oils. Furthermore, the effects of microwave roasting of the seds compared to regular roasting (control) were determined. The oil yield of orange seed cold pressing was around 52.93–62.99%. After cold pressing, 13.57–17.97% oil remained in the meal together with 20.68–25.61% protein. Hence, pressed meals could be valorized for different purposes. Except for turbidity, the color b* value, free acidity, the p-anisidine value and antioxidant capacity, there was no significant difference between the two oil samples for the measured physicochemical properties. Six different fatty acids were quantified and the major fatty acids were linoleic, palmitic and oleic acids. The fatty acid composition of the orange seed oil can be accepted as nutritionally balanced. Among the fifteen sterols quantified, β-sitosterol was dominant (around 77–78%). Likewise, the α-tocopherol content of the samples was not significantly different. The thermal onset and peak temperatures, and enthalpies for crystallization and melting were also reported. This study showed that good quality orange seed oils can be produced by cold pressing, and the oils could be used in food and non-food applications. [es

Full Text Available Mao seed is a by-product of the wine and juice industry, which could be used in animal nutrition. The current study was designed to determine the effect of supplementation of mao (Antidesma thwaitesianum Muell. Arg. seed meal (MOSM containing condensed tannins (CT on rumen fermentation, nitrogen (N utilization and microbial protein synthesis in goats. Four crossbred (Thai Native×Anglo Nubian goats with initial body weight (BW 20±2 kg were randomly assigned to a 4×4 Latin square design. The four dietary treatments were MOSM supplementation at 0%, 0.8%, 1.6%, and 2.4% of total dry matter (DM intake, respectively. During the experimental periods, all goats were fed a diet containing roughage to concentrate ratio of 60:40 at 3.0% BW/d and pangola grass hay was used as a roughage source. Results showed that supplementation with MOSM did not affect feed intake, nutrient intakes and apparent nutrient digestibility (p>0.05. In addition, ruminal pH and ammonia nitrogen (NH3-N were not influenced by MOSM supplementation, whilst blood urea nitrogen was decreased quadraticly (p0.05. There were linear decreases in urinary N (p0.05. From the current study, it can be concluded that supplementation of MOSM at 1.6% to 2.4% of total DM intake can be used to modify ruminal fermentation, especially propionate and N utilization in goats, without affecting the nutrient digestibility, microbial populations and microbial protein synthesis.

Field experiments were conducted in open top chamber during rabi seasons of 2009-10 and 2010-11 at the research farm of the Indian Agricultural Research Institute, New Delhi to study the effect of tropospheric ozone (O3) and carbon dioxide (CO2) interaction on yield and nutritional quality of Indian mustard (Brassica juncea (L.) Czern.). Mustard plants were grown from emergence to maturity under different treatments: charcoal-filtered air (CF, 80-85 % less O3 than ambient O3 and ambient CO2), nonfiltered air (NF, 5-10 % less O3 than ambient O3 and ambient CO2 ), nonfiltered air with elevated carbon dioxide (NF + CO2, NF air and 550 ± 50 ppm CO2), elevated ozone (EO, NF air and 25-35 ppb elevated O3), elevated ozone along with elevated carbon dioxide (EO + CO2, NF air, 25-35 ppb O3 and 550 ± 50 ppm CO2), and ambient chamber less control (AC, ambient O3 and CO2). Elevated O3 exposure led to reduced photosynthesis and leaf area index resulting in decreased seed yield of mustard. Elevated ozone significantly decreased the oil and micronutrient content in mustard. Thirteen to 17 ppm hour O3 exposure (accumulated over threshold of 40 ppm, AOT 40) reduced the oil content by 18-20 %. Elevated CO2 (500 ± 50 ppm) along with EO was able to counter the decline in oil content in the seed, and it increased by 11 to 13 % over EO alone. Elevated CO2, however, decreased protein, calcium, zinc, iron, magnesium, and sulfur content in seed as compared to the nonfiltered control, whereas removal of O3 from air in the charcoal-filtered treatment resulted in a significant increase in the same.

2014-05-01

Full Text Available Dietary R-sulforaphane is a highly potent inducer of the Keap1/Nrf2/ARE pathway. Furthermore, sulforaphane is currently being used in clinical trials to assess its effects against different tumour processes. This study reports an efficient preparation of enantiopure R-sulforaphane based on the enzymatic hydrolysis of its natural precursor glucoraphanin. As an alternative to broccoli seeds, we have exploited Tuscan black kale seeds as a suitable source for gram-scale production of glucoraphanin. The defatted seed meal contained 5.1% (w/w of glucoraphanin that was first isolated through an anion exchange chromatographic process, and then purified by gel filtration. The availability of glucoraphanin (purity ≈ 95%, weight basis has allowed us to develop a novel simple hydrolytic process involving myrosinase (EC 3.2.1.147 in a biphasic system to directly produce R-sulforaphane. In a typical experiment, 1.09 g of enantiopure R-sulforaphane was obtained from 150 g of defatted Tuscan black kale seed meal.

Full Text Available ABSTRACT The 4-week study was conducted with 180 Lohmann Brown layers (52 weeks of age. The layers were assigned to three groups (C, E1 and E2. The basal diet (group C consisted mainly of corn, soybean meal and corn gluten, and contained 19% crude protein and 11.58 MJ/kg metabolizable energy. The diets for groups E1 and E2 differed from group C by the inclusion of 5% flax meal and of dietary antioxidants. The concentration of α-linolenic acid in the fat of E1 and E2 diets was almost 10 times higher than in group C. E1 diet was supplemented with vitamin E (100 mg/kg feed, DM, while E2 diet was supplemented with 2% grape seed meal (polyphenols: 630.890 µg gallic acid equivalents/g sample; flavonoids: 5.065 µg rutin equivalents/g sample; antioxidant capacity: 28.468 mM trolox equivalents/g sample. The antioxidant capacity of E2 was higher than in C, but lower than in E1. Haugh units of the eggs (18 eggs/group harvested during the last experimental week were not significantly different among groups. The ω-6/ω-3 polyunsaturated fatty acids (PUFAs ratio in the fat from the eggs was 4.46 ± 0.11 (E1 and 4.52 ± 0.21 (E2, three times lower (p<0.05 than the control group (14.70 ± 0.43.

Alleviation of cadmium toxicity in Brassica juncea L. (Czern. & Coss. by calcium application involves various physiological and biochemical strategies.

Directory of Open Access Journals (Sweden)

Parvaiz Ahmad

Full Text Available Calcium (Ca plays important role in plant development and response to various environmental stresses. However, its involvement in mitigation of heavy metal stress in plants remains elusive. In this study, we examined the effect of Ca (50 mM in controlling cadmium (Cd uptake in mustard (Brassica juncea L. plants exposed to toxic levels of Cd (200 mg L(-1 and 300 mg L(-1. The Cd treatment showed substantial decrease in plant height, root length, dry weight, pigments and protein content. Application of Ca improved the growth and biomass yield of the Cd-stressed mustard seedlings. More importantly, the oil content of mustard seeds of Cd-stressed plants was also enhanced with Ca treatment. Proline was significantly increased in mustard plants under Cd stress, and exogenously sprayed Ca was found to have a positive impact on proline content in Cd-stressed plants. Different concentrations of Cd increased lipid peroxidation but the application of Ca minimized it to appreciable level in Cd-treated plants. Excessive Cd treatment enhanced the activities of antioxidant enzymes superoxide dismutase, ascorbate peroxidase and glutathione reductase, which were further enhanced by the addition of Ca. Additionally, Cd stress caused reduced uptake of essential elements and increased Cd accumulation in roots and shoots. However, application of Ca enhanced the concentration of essential elements and decreased Cd accumulation in Cd-stressed plants. Our results indicated that application of Ca enables mustard plant to withstand the deleterious effect of Cd, resulting in improved growth and seed quality of mustard plants.

Brassica juncea is a chief oil yielding crop in many parts of the world including India. With advancement of molecular techniques, RT-qPCR based study of gene-expression has become an integral part of experimentations in crop breeding. In RT-qPCR, use of appropriate reference gene(s) is pivotal. The virtue of the reference genes, being constant in expression throughout the experimental treatments, needs to be validated case by case. Appropriate reference gene(s) for normalization of gene-expression data in B. juncea during the biotic stress of aphid infestation is not known. In the present investigation, 11 reference genes identified from microarray database of Arabidopsis-aphid interaction at a cut off FDR ≤0.1, along with two known reference genes of B. juncea, were analyzed for their expression stability upon aphid infestation. These included 6 frequently used and 5 newly identified reference genes. Ranking orders of the reference genes in terms of expression stability were calculated using advanced statistical approaches such as geNorm, NormFinder, delta Ct and BestKeeper. The analysis suggested CAC, TUA and DUF179 as the most suitable reference genes. Further, normalization of the gene-expression data of STP4 and PR1 by the most and the least stable reference gene, respectively has demonstrated importance and applicability of the recommended reference genes in aphid infested samples of B. juncea.

Indian mustard [Brassica juncea (L.) Czern. & Coss. (Brassicaceae)] is reported to possess diverse pharmacological properties. However, limited information is available concerning its hepatoprotective activity and mechanism of action. To study the protective mechanism of mustard seed extract against acetaminophen (APAP) toxicity in a hepatocellular carcinoma (HepG2) cell line. Hepatotoxicity models were established using APAP (2.5-22.5 mM) based on the cytotoxicity profile. An antioxidant-rich fraction from mustard seeds was extracted and evaluated for its hepatoprotective potential. The mechanism of action was elucidated using various in vitro antioxidant assays, the detection of intracellular generation of reactive oxygen species (ROS), and cell cycle analysis. The phytoconstituents isolated via HPLC-DAD were also evaluated for hepatoprotective activity. Hydromethanolic seed extract exhibited hepatoprotective activity in post- and pre-treatment models of 20 mM APAP toxicity and restored the elevated levels of liver indices to normal values (p DAD analysis revealed the presence quercetin, vitamin E, and catechin, which exhibited hepatoprotective activity. A phytoextract of mustard seeds acts by suppressing the generation of ROS in response to APAP toxicity.

The purpose of this study was to compare the behavior of the root system of one of the most frequently cited species in phytoremediation Indian mustard [Brassica juncea (L.) Czern.] and a representative perennial herb (Bidens pilosa L.) native of Argentina, for different concentrations of lead in soils through chemical and visualization techniques of the rhizosphere. Lead polluted soils from the vicinity of a lead recycling plant in the locality of Bouwer, were used in juxtaposed rhizobox systems planted with seedlings of B. juncea and B. pilosa with homogeneous and heterogeneous soil treatments. Root development, pH changes in the rhizosphere, dry weight biomass, lead content of root and aerial parts and potential extraction of lead by rhizosphere exudates were determined. In both species lead was mainly accumulated in roots. However, although B. juncea accumulated more lead than B. pilosa at elevated concentrations in soils, the latter achieved greater root and aerial development. No changes in the pH of the rhizosphere associated to lead were observed, despite different extractive potentials of lead in the exudates of the species analyzed. Our results indicated that Indian mustard did not behave as a hyperaccumulator in the conditions of the present study.

New sources of soybean seed meal and oil composition traits identified through TILLING

2009-07-01

Full Text Available Abstract Background Several techniques are available to study gene function, but many are less than ideal for soybean. Reverse genetics, a relatively new approach, can be utilized to identify novel mutations in candidate genes; this technique has not produced an allelic variant with a confirmed phenotype in soybean. Soybean raffinose synthase genes and microsomal omega-6 fatty acid desaturase genes were screened for novel alleles in mutagenized soybean populations. Results Four mutations in independent lines were identified in the raffinose synthase gene RS2; two mutations resulted in amino acid mutations and one resulted in an altered seed oligosaccharide phenotype. The resulting phenotype was an increase in seed sucrose levels as well as a decrease in both raffinose and stachyose seed oligosaccharide levels. Three mutations in independent lines were identified in the omega-6 fatty acid desaturase gene FAD2-1A; all three mutations resulted in missense amino acid mutations and one resulted in an altered seed fatty acid profile that led to an increase in oleic acid and a decrease in linoleic acid in the seed oil. Conclusion The oligosaccharide phenotype controlled by the novel RS2 allele is similar to previously observed seed oligosaccharide phenotypes in RS2 mutant (PI 200508 allele-containing lines. Due to the anti-nutritional characteristics of raffinose and stachyose, this represents a positive change in seed composition. The fatty acid phenotype controlled by the novel FAD2-1A allele controls an increase in oleic acid in the seed oil, a phenotype also observed in a line previously characterized to have a null allele of the FAD2-1A gene. Molecular marker assays were developed to reliably detect the inheritance of the mutant alleles and can be used in efficient breeding for these desired seed phenotypes. Our results serve as the first demonstration of the identification of soybean mutants controlling seed phenotypes discovered through the

This study evaluated the effects of replacing soybean meal (SBM) with rubber seed meal (RSM) on growth, antioxidant capacity, non-specific immune response and resistance to Aeromonas hydrophila in tilapia (Oreochromis niloticus × Oreochromis aureus). Five experimental diets were formulated with 0 (control), 10, 20, 30, and 40% RSM replacing graded levels of SBM, respectively. Fish were fed one of the five experimental diets for eight weeks, and then challenged by A. hydrophila via intraperitoneal injection and kept for seven days. Dietary RSM inclusion level up to 30% did not affect the weight gain and daily growth coefficient, whereas these were depressed by a further inclusion. Fish fed diet with 40% RSM showed the lowest serum total antioxidant capacity, lysozyme, alternative complement pathway, respiratory burst and phagocytic activities. Dietary RSM inclusion gradually depressed the post-challenge survival rate, and that was significantly lower in fish fed diet with 40% RSM compared to fish fed the control diet. Conversely, the inclusion of RSM generally increased the serum total cholesterol level, the plasma alanine aminotransferase and aspartate aminotransferase activities, and these were significantly higher in fish fed diet with 40% RSM compared to fish fed the control diet. The results indicated that RSM can be included at level up to 30% in diet for tilapia without obvious adverse effects on the growth, antioxidant capacity, non-specific immune response and resistance to A. hydrophila infection, whereas these were depressed by a further inclusion.

KEY MESSAGE: oxa CMS is a new cytoplasmic male sterility type in Brassica juncea. oxa CMS is a cytoplasmic male sterility (CMS) line that has been widely used in the production and cultivation of stem mustard in the southwestern China. In this study, different CMS-type specific mitochondrial markers were used to confirm that oxa CMS is distinct from the pol CMS, ogu CMS, nap CMS, hau CMS, tour CMS, Moricandia arvensis CMS, orf220-type CMS, etc., that have been previously reported in Brassica crops. Pollen grains of the oxa CMS line are sterile with a self-fertility rate of almost 0% and the sterility strain rate and sterility degree of oxa CMS is 100% due to a specific flower structure and flowering habit. Scanning electron microscopy revealed that most pollen grains in mature anthers of the oxa CMS line are empty, flat and deflated. Semi-thin section further showed that the abortive stage of anther development in oxa CMS is initiated at the late uninucleate stage. Abnormally vacuolated microspores caused male sterility in the oxa CMS line. This cytological study combined with marker-assisted selection showed that oxa CMS is a novel CMS type in stem mustard (Brassica juncea). Interestingly, the abortive stage of oxa CMS is later than those in other CMS types reported in Brassica crops, and there is no negative effect on the oxa CMS line growth period. This study demonstrated that this novel oxa CMS has a unique flower structure with sterile pollen grains at the late uninucleate stage. Our results may help to uncover the mechanism of oxa CMS in Brassica juncea.

Agrobacterium mediated transformation of brassica juncea (l.) czern with chitinase gene conferring resistance against fungal infections

International Nuclear Information System (INIS)

Ahmad, B.; Ambreen, S.; Khan, I.

2015-01-01

Brassica juncea (Czern and Coss., L.) is an important oilseed crop. Since it is attacked by several bacterial and fungal diseases, therefore, we developed an easy and simple protocol for the regeneration and transformation of B. juncea variety RAYA ANMOL to give rise to transgenic plants conferring resistance against various fungal diseases. The transformation was carried out using Agrobacterium with Chitinase gene. This gene was isolated from Streptomyces griseus HUT6037. We used two types of explants for transformation i.e. hypocotyls and cotyledons. Only hypocotyls explants showed good results regarding callus initiation. Different hormonal concentrations were applied i.e. BAP 2, 4 and 6 mgL-1 and NAA 0.1, 0.2 and 0.3 mgL-1. However, high transformation efficiency was observed by supplementing the medium with combination of 2 mgL-1 BAP and 0.2 mgL-1 for initiation of callus. Similarly 10 mgL-1 kanamycin and 200 mgL-1 cefotaxime also proved successful for the selection of transformed callus. In order to confirm the presence of transgenic callus Polymerase chain reaction was performed using specific primers for Chitinase gene. (author)

Full Text Available Sunn hemp (Crotalaria juncea L. is a tropical legume that produces plant biomass and nitrogen (N quickly. Our objectives were to assess the growth of a new sunn hemp cultivar breed to produce seed in a temperate climate and determine the residual N effect on a rye (Secale cereale L. cover crop in east-central Alabama from 2007 to 2009. Plant populations, plant height, stem diameter, biomass production, and N content were determined for two sunn hemp planting dates, following corn (Zea mays L. and wheat (Triticum aestivum L. harvest, across different seeding rates (17, 34, 50, and 67 kg/ha. Rye biomass was measured the following spring. Sunn hemp biomass production was inconsistent across planting dates, but did relate to growing degree accumulation. Nitrogen concentrations were inversely related to biomass production, and subsequent N contents corresponded to biomass levels. Neither planting date nor seeding rate affected rye biomass production, but rye biomass averaged over both planting dates following wheat/sunn hemp averaged 43% and 33% greater than rye following fallow. Rye biomass following corn/sunn hemp was equivalent to fallow plots. Early planting dates are recommended for sunn hemp with seeding rates between 17 and 34 kg/ha to maximize biomass and N production.

Two crops of Brassica juncea (L.) Czern. were grown in a field experiment, at the site affected by the toxic spillage of acidic, metal-rich waste in Aznalcollar (Seville, Spain), to study its metal accumulation and the feasibility of its use for metal phytoextraction. The effects of organic soil amendments (cow manure and mature compost) and lime on biomass production and plant survival were also assessed; plots without organic amendment and without lime were used as controls. Plots, with or without organic amendment, having pH<5 were limed for the second crop. Soil acidification conditioned plant growth and metal accumulation. The addition of lime and the organic amendments achieved higher plant biomass production, although effects concerning metal bioavailability and accumulation were masked somewhat by pH variability with time and between and within plots. Tissue metal concentrations of B. juncea were elevated for Zn, Cu and Pb, especially in leaves of plants from plots with low pH values (maxima of 2029, 71 and 55 {mu}g g{sup -1}, respectively). The total uptake of heavy metals in the plants was relatively low, emphasising the problems faced when attempting to employ phytoextraction for clean-up of pluri-contaminated sites. - Although organic amendments improved soil conditions and plant growth, the phytoextraction capacity of Brassica juncea (cv. Z1) is too low for efficient soil remediation.

Transfer of thallium from rape seed to rape oil is negligible and oil is fit for human consumption.

Science.gov (United States)

Loula, Martin; Kaňa, Antonín; Vosmanská, Magda; Koplík, Richard; Mestek, Oto

2016-01-01

Rape and other Brassicaceae family plants can accumulate appreciable amounts of thallium from the soil. Because some species of this family are common crops utilised as food for direct consumption or raw materials for food production, thallium can enter the food chain. A useful method for thallium determination is inductively coupled plasma mass spectrometry. The limit of detection (0.2 pg ml(-1) Tl or 0.02 ng g(-1) Tl, taking in the account dilution during sample decomposition) found in the current study was very low, and the method can be used for ultra-trace analysis. Possible transfer of thallium from rape seed to the rape oil was investigated in two ways. The balance of thallium in rape seed meal (content 140-200 ng g(-1) Tl) and defatted rape seed meal indicated that thallium did not pass into the oil (p thallium in six kinds of edible rape seed oil and three kinds of margarines showed that the amount of thallium in rape seed oil is negligible.

Arsenic is recognised as a toxic metalloid and a strong pollutant in soils of many countries. Thus, the reclamation of contaminated areas is fundamental in order to protect both human health and agricultural production. This study is focused on the assisted phytoextraction, a technology for reclaiming polluted soils that takes advantage of the capability of some plants to extract inorganic elements from soils with the aid of additive agents. The nutrients phosphorus, as phosphate, and sulphur, as thiosulphate, can compete with the form more oxidised of arsenic, both in soil and plant. This study examined the capability of thiosulphate (Th) and phosphate (Ph) to promote the release of As from soil surfaces in order to improve the phytoavailability and thus the absorption of As by Brassica juncea plants. In the first experiment B. juncea plants were grown on a soil that had been sampled from an industrial area strongly contaminated by As (790 mg As kg-1 soil). The second experiment was carried out in hydroponics where As has been added at a concentration (100 microM) similar to the As available concentration measured in soil. In both trials ammonium thiosulphate (at the concentration of 0.27 M in soil, and 400 microM in hydroponics) and potassium hydrogen phosphate (at the concentration of 0.05 M in soil, and 112 microM in hydroponics) were added. The biomass of B. juncea was determined and the accumulation of P, S and As in root and in the above-ground tissues have been analyzed. Our results showed that thiosulphate and phosphate acted either as nutrients and detoxifying agents, due to the stimulation of plant defensive systems, and influenced either the biomass production and the As accumulation in plant tissues. In the plants grown in soil, As accumulated at higher levels in the above-ground part than in the roots and the addition of Th induced a higher biomass production and a higher total As accumulation (concentration x biomass) in the above-ground tissues

Two samples of tomato seeds, a by-product of the tomato canning industry were evaluated to determine proximate analysis, amino acid content, and digestibility, TMEn, and protein efficiency ratio. Tomato seeds were also used to replace corn and soybean meal (SBM) in a chick diet on an equal true amino acid digestibility and TMEn basis. Tomato seeds were found to contain 8.5% moisture, 25% CP, 20.0% fat, 3.1% ash, 35.1% total dietary fiber, 0.12% Ca, 0.58% P, and 3,204 kcal/kg of TMEn. The total amounts of methionine, cystine, and lysine in the tomato seeds were 0.39, 0.40, and 1.34%, respectively, and their true digestibility coefficients, determined in cecectomized roosters, were 75, 70, and 54%, respectively. The protein efficiency ratio (weight gain per unit of protein intake) value when fed to chicks at 9% CP was 2.5 compared to 3.6 for SBM (P seeds could replace corn and SBM without any adverse affects on chick weight gain, feed intake, or gain:feed ratio from 8 to 21 d posthatch. Tomato seeds at any level in the diet did not significantly affect skin pigmentation. Although the protein quality of tomato seeds may not be as high as SBM, tomato seeds do contain substantial amounts of digestible amino acids and TMEn. When formulating diets on a true digestible amino acid and TMEn basis, tomato seeds can be supplemented into chick rations at up to 15% without any adverse affects on growth performance.

2016-01-01

In plants, several cellular and metabolic pathways interact with each other to regulate processes that are vital for their growth and development. Carbon (C) and Nitrogen (N) are two main nutrients for plants and coordination of C and N pathways is an important factor for maintaining plant growth and development. In the present work, influence of nitrogen and sucrose (C source) on growth parameters and expression of genes involved in nitrogen transport and assimilatory pathways was studied in B. juncea seedlings. For this, B. juncea seedlings were treated with four combinations of C and N source viz., N source alone (-Suc+N), C source alone (+Suc-N), with N and C source (+Suc+N) or without N and C source (-Suc-N). Cotyledon size and shoot length were found to be increased in seedlings, when nitrogen alone was present in the medium. Distinct expression pattern of genes in both, root and shoot tissues was observed in response to exogenously supplied N and C. The presence or depletion of nitrogen alone in the medium leads to severe up- or down-regulation of key genes involved in N-uptake and transport (BjNRT1.1, BjNRT1.8) in root tissue and genes involved in nitrate reduction (BjNR1 and BjNR2) in shoot tissue. Moreover, expression of several genes, like BjAMT1.2, BjAMT2 and BjPK in root and two genes BjAMT2 and BjGS1.1 in shoot were found to be regulated only when C source was present in the medium. Majority of genes were found to respond in root and shoot tissues, when both C and N source were present in the medium, thus reflecting their importance as a signal in regulating expression of genes involved in N-uptake and assimilation. The present work provides insight into the regulation of genes of N-uptake and assimilatory pathway in B. juncea by interaction of both carbon and nitrogen. PMID:27637072

2018-01-01

The nutritional value of raw Jack bean meal ( Canavalia ensiformis ) as a partial substitute for soybeans meal was investigated in this study. Preliminary investigation on nutrient composition revealed that lysine, histidine, and phenylalanine were significantly higher in C .  ensiformis seed meal compared to soybean meal. However, crude protein and other essential amino acids were significantly lower. Feeding trial was then conducted to investigate the effect of replacing about 40% soybeans meal (at 58.8% inclusion) with C .  ensiformis in the diet of Clarias gariepinus . The result obtained after 56 days revealed that fingerlings could tolerate up to 20% replacement without significant effect on growth and nutrient utilization. Beyond this, growth was significantly reduced. Survivals of the fish also follow a similar trend as stated above. It was concluded that dietary inclusion of raw C .  ensiform meal should not be beyond 11% (or 20% replacement for soybeans meal included at 58.8%) in the diet of C .  gariepinus .

Full Text Available The aim of the research is to predict specific output characteristics of half finished goods (crude sunflower oil and meal on the basis of specific input variables (quality and composition of sunflower seeds, with the help of artificial neural networks. This is an attempt to predict the amount much more precisely than is the case with technological calculations commonly used in the oil industry. All input variables are representing the data received by the laboratory, and the output variables except category % of oil which is obtained by measuring the physical quantity of produced crude sunflower oil and sunflower consumed quantity of the processing quality. The correct prediction of the output variables contributes to better sales planning, production of sunflower oil, and better use of storage. Also, the correct prediction of technological results of the quality of crude oil and meal provides timely response and also preventing getting rancid and poor-quality oil, timely categorizing meal, which leads to proper planning and sales to the rational utilization of storage space, allows timely response technologists and prevents the growth of microorganisms in the meal.

This study aims to examine associations between parents' report of eating family meals while growing up and their current family meal frequency, routines, and expectations. Baseline data were used from the Healthy Home Offerings via the Mealtime Environment (HOME) Plus study, a randomized controlled trial with a program to promote healthful behaviors and family meals at home. Participants (160 parent/child dyads) completed data collection in 2011-2012 in the Minneapolis/St. Paul, MN metropolitan area. Parents were predominately female (95%) and white (77%) with a mean age of 41.3 years. General linear modeling examined relationships between parents' report of how often they ate family meals while growing up and their current family meal frequency, routines, and expectations as parents, controlling for parent age, education level, and race. Parental report of eating frequent family meals while growing up was positively and significantly associated with age, education, and self-identification as white (all p meals less than three times/week or four to five times/week, parents who ate six to seven family meals/week while growing up reported significantly more frequent family meals with their current family (4.0, 4.2 vs. 5.3 family meals/week, p = .001). Eating frequent family meals while growing up was also significantly and positively associated with having current regular meal routines and meal expectations about family members eating together (both p meals with children may have long-term benefits over generations.

1978-01-01

Experiments were carried out to confirm whether the irradiation treatment of rapeseed meal with gamma rays was effective in reducing the goitrogenic effect of meal, and to obtain the information on the reasonable dose level to reduce the above effect. The rapeseed meals from two ordinary and one non-commercial low glucosinolate (Brassica napus L. cv. Bronowski) seeds were exposed to gamma rays of 5, 10, 50 and 100 Mrad respectively. And the changes in oxazolidinethone (OZT) content of these meals by the irradiation were investigated compared with those by the autoclaving treatment under the reasonable condition. The influences of irradiation treatment on the content of the several constituents of meal were also examined. Furthermore, with chicks, the influences of irradiation treatment on the palatability of meal and on the apparent digestibility of its crude protein or crude fiber were investigated. When two ordinary meals were irradiated at the level of 50 Mrad or above, their OZT content reduced to the level of that in a low glucosinolate meal (Bronowski meal) and such irradiation dosages also resulted in a loss of the available lysine (AL) of meals. The extent of the above changes in the contents of OZT and AL was similar to that in rapeseed meal which was autoclaved under the reasonable condition. Treatment at irradiation dosage of either 50 or 100 Mrad resulted in lower crude fiber and higher reducing sugar content than those of non-irradiated meal respectively. Tests with chicks revealed that an irradiation treatment tended to improve the palatability and the crude fiber digestibility of meal but had no appreciable effect on the digestibility of its crude protein. In summary, these findings indicate that the gamma irradiation at dosage of 50 Mrad or above as well as the autoclaving treatment under the reasonable condition is effective in reducing the goitrogenic effect of rapeseed meal.

Full Text Available The study quantified the effects of Camelina seeds and buckthorn meal on broiler carcass production and quality. Camelina seeds and buckthorn meal were incorporated in the compound feeds for finishing broilers as natural source of vitamins (beta- carotene, vitamins C, B1, B2, E, F, calcium, phosphorus, magnesium, potassium, sodium, and iron. The experiment was conducted on 600 Hybro PN broilers during the age period 7 – 42 days. The broilers were assigned to 3 groups, a control group © and two experimental groups (E1 and E2, each with 200 broilers (3 groups  3 replicates  100 broilers. Three (phase-feeding compound feeds formulations were used. The control diet consisted mainly of corn, full fat soybean, soybean meal and corn gluten. Camelina seeds (10% replaced full fat soybean in the experimental groups, while additionally, in E2 the classical premix with synthetic vitamins and minerals was replaced by buckthorn meal. The partial results show that the use of Camelina seeds reduced significantly (P<0.05 the final live weight, but the liveability percentage was not influenced by the type of dietary compound feed throughout the experimental period. Carcass fat decreased by 61.44% and 30.72% in the experimental groups compared to the control group. Total proteins increased in average by 3-10% concomitantly with the increase of the water content, fat decreased in average by 1.5-4%, the energy value also decreased proportionally with the fat in the experimental groups compared to the control group. Water retention capacity increased by 1% in E2.

Makkar, H P; Becker, K; Schmook, B

1998-01-01

Seven seed samples of J. curcas, both in raw and roasted state, sold in some villages in Quintana Roo state, Mexico for human consumption were analyzed for physical characteristics, nutrients and antinutrients. The average seed weight varied from 0.53 to 0.74 g and kernel weight as proportion of raw seed weight was from 61 to 66%. The contents of crude protein, lipid and ash of kernels from raw seeds were 27-30%, 55-62% and 3.7-5.2% respectively. The levels of antinutrients in meal from the raw seeds were: trypsin inhibitor activity (14.6-28.7 mg trypsin inhibited/g), lectin (25.6-52.2 unit; one unit is the reverse of minimum amount of mg meal/ml assay which produced haemagglutination), saponins (1.9-2.3% as diosgenin equivalent) and phytate (8.4-10%). Phorbol esters in kernels from raw seeds were not detected in four samples and in other three samples it ranged from 0.01 to 0.02 mg/g as phorbol-12-myristate 13-acetate equivalent. Roasting of seeds inactivated almost 100% of trypsin inhibitor activity. Although lectin activity reduced on roasting, it was still present in high amounts. Saponins, phytate and phorbol esters were not affected by roasting.

Phytic acid (PA) contains the major portion of the phosphorus in the soybean (Glycine max) seed and chelates divalent cations. During germination, both minerals and phosphate are released upon phytase-catalyzed degradation of PA. We generated a soybean line (CAPPA) in which an Escherichia coli periplasmic phytase, the product of the appA gene, was expressed in the cytoplasm of developing cotyledons. CAPPA exhibited high levels of phytase expression, ≥90% reduction in seed PA, and concomitant increases in total free phosphate. These traits were stable, and, although resulted in a trend for reduced emergence and a statistically significant reduction in germination rates, had no effect on the number of seeds per plant or seed weight. Because phytate is not digested by monogastric animals, untreated soymeal does not provide monogastrics with sufficient phosphorus and minerals, and PA in the waste stream leads to phosphorus runoff. The expression of a cytoplasmic phytase in the CAPPA line therefore improves phosphorus availability and surpasses gains achieved by other reported transgenic and mutational strategies by combining in seeds both high phytase expression and significant increases in available phosphorus. Thus, in addition to its value as a high-phosphate meal source, soymeal from CAPPA could be used to convert PA of admixed meals, such as cornmeal, directly to utilizable inorganic phosphorus.

The objective was to compare the effects of ad libitum consumption of commonly consumed meal-time beverages on energy and fluid intakes and post-meal average subjective appetite and blood glucose in healthy adults. In a randomized controlled design, 29 males and females consumed to satiation an ad libitum pizza meal with one of five beverages in unlimited amount including water (0 kcal), 1% milk (44 kcal/100 ml), regular cola (44 kcal/100 ml), orange juice (44 kcal/100 ml) and diet cola (0 kcal). Food and fluid intakes were measured at the meal. Average subjective appetite and blood glucose were measured before and for 2h after the meal. Although energy intake from pizza was similar among all beverage treatments, the amount of fluid consumed (g) varied among the beverages with intake of orange juice higher than regular and diet cola, but not different from water or milk. Meal-time ingestion of caloric beverages, milk, orange juice and regular cola, led to higher total meal-time energy intakes compared to either water or diet cola. Post-meal blood glucose area under the curve (AUC) was lower after milk than after meals with water, orange juice and regular cola and post-meal average subjective appetite AUC was lower after milk than after meals with water. Meal intakes of nutrients including protein, calcium, phosphorus, zinc, vitamins B12, A and D were higher at the meal with milk compared to the other beverages. Thus, caloric beverages consumed ad libitum during a meal add to total meal-time energy intake, but 1% milk favors a lower post-meal blood glucose and average subjective appetite score and adds to nutrient intake.

Okada, Satoshi; Fukutani, Satoshi; Takahashi, Tomoyuki; Fukui, Masami

2004-01-01

Phytoremediation is a new method that uses plants to remove contaminants from soil without affecting soil fertility. It can therefore be used for contaminated agricultural land. Indian mustard (Brassica juncea) and sunflower (Helianthus annuus L.) are used in phytoremediation to remove Cadmium (Cd), which they can accumulate in large quantities. It is important to know when plants have accumulated significant Cd, so that we can decide when the plants should be harvested and synthetic chelates applied. Brassica juncea seeds and Helianthus annuus L. seeds were planted in a field in Kyoto University Research Reactor Institute (KUR). Brassica juncea and Helianthus annuus L. were collected at time intervals ranging from 1 to 6 months and 2 to 7 weeks, respectively, after seedling emergence and the concentration of Cd in the plants was analyzed. These results indicated that Brassica juncea should be harvested before beginning flowering and Helianthus annuus L. should be harvested after it becomes old enough. The solubility of Cd in soil is enhanced when the soil is heated or dried, and black vinyl mulch was therefore used to absorb the heat from sunlight. The difference in the Cd uptake of Brassica juncea between mulching cultivation and non-mulching cultivation was investigated in a field, and this indicated that there is no probability that mulching enhances Cd uptake in plants. The solubility of Cd in soil decreases over time. Repeated pot experiments were done. We planted Brassica juncea in pots, and investigated the uptake of Cd and the solid phase fractions in which Cd was present in each pot experiment. These did not change considerably over time, indicating that age has a negligible effect on Cd uptake in plants. (author)

A hemp seed protein isolate, prepared from defatted hemp seed meals by alkaline solubilization/acid precipitation, was subjected to extensive chemical hydrolysis under acid conditions (6 M HCl). The resulting hydrolysate was fractionated by semipreparative RP-HPLC, and the purified fractions were tested as inhibitors of angiotensin converting enzyme (ACE). Mono- and bidimensional NMR experiments and LC-MS analyses led to the identification of four potentially bioactive peptides, i.e. GVLY, IEE, LGV, and RVR. They were prepared by solid-phase synthesis, and tested for ACE-inhibitory activity. The IC 50 values were GVLY 16 ± 1.5 μM, LGV 145 ± 13 μM, and RVR 526 ± 33 μM, confirming that hemp seed may be a valuable source of hypotensive peptides.

Cationic antimicrobial peptides (CAPs) have shown potential against broad spectrum of phytopathogens. Synthetic versions with desirable properties have been modeled on these natural peptides. MsrA1 is a synthetic chimera of cecropin A and melittin CAPs with antimicrobial properties. We generated transgenic Brassica juncea plants expressing the msrA1 gene aimed at conferring fungal resistance. Five independent transgenic lines were evaluated for resistance to Alternaria brassicae and Sclerotinia sclerotiorum, two of the most devastating pathogens of B. juncea crops. In vitro assays showed inhibition by MsrA1 of Alternaria hyphae growth by 44-62 %. As assessed by the number and size of lesions and time taken for complete leaf necrosis, the Alternaria infection was delayed and restricted in the transgenic plants with the protection varying from 69 to 85 % in different transgenic lines. In case of S. sclerotiorum infection, the lesions were more severe and spread profusely in untransformed control compared with transgenic plants. The sclerotia formed in the stem of untransformed control plants were significantly more in number and larger in size than those present in the transgenic plants where disease protection of 56-71.5 % was obtained. We discuss the potential of engineering broad spectrum biotic stress tolerance by transgenic expression of CAPs in crop plants.

Television, Home-Cooked Meals, and Family Meal Frequency: Associations with Adult Obesity.

Science.gov (United States)

Tumin, Rachel; Anderson, Sarah E

2017-06-01

Adults, regardless of whether they are parents, regularly eat meals with family at home, but few studies have analyzed large, population-based samples to examine how mealtime practices or family meal frequency are associated with health. The aim of this study was to evaluate associations between the frequency of family meals eaten at home, watching television or videos during family meals, and consumption of meals that were cooked and eaten at home and the odds of being obese in adults. This was an analysis of the cross-sectional 2012 Ohio Medicaid Assessment Survey (OMAS), a telephone survey of Ohio's population. The study sample was adult Ohio residents responding to the 2012 OMAS who ate at least one family meal in the past week (n=12,842). Obesity (body mass index [BMI] ≥30), calculated from self-reported height and weight, was the outcome. Logistic regression models were used to examine the association between obesity and family meal practices, adjusted for respondents' employment status, marital status, race/ethnicity, educational attainment, and age. Family meal frequency was not associated with odds of obesity: those who ate family meals most (6-7) days were as likely as those who ate family meals few (1-2) days to be obese (adjusted odds ratio [OR adj ]=1.01, 95% CI=0.86, 1.18). Thirty-six percent of adults never watched television or videos while eating family meals, and 62% ate family meals that were all home-cooked. Adults who never watched television or videos during family meals had 37% lower odds of obesity compared with those who always did (95% CI=0.54, 0.73), regardless of family meal frequency. Adults whose family meals were all home-cooked had 26% lower odds of obesity than those who ate some or no home-cooked family meals (95% CI=0.62, 0.88). This association was more pronounced among adults who ate few family meals. Family meal practices may be associated with obesity in adults, even if they eat few family meals per week.

2011-10-01

Jatropha curcas L. has been promoted as an oilseed crop for use to meet the increased world demand for vegetable oil production, and in particular, as a feedstock for biodiesel production. Seed meal is a protein-rich by-product of vegetable oil extraction, which can either be used as an organic fertilizer, or converted to animal feed. However, conversion of J. curcas seed meal into animal feed is complicated by the presence of toxins, though plants producing "edible" or "non-toxic" seeds occur in Mexico. Toxins present in the seeds of J. curcas include phorbol esters and a type-I ribosome inactivating protein (curcin). Although the edible seeds of J. curcas are known to lack phorbol esters, the curcin content of these seeds has not previously been studied. We analyzed the phorbol ester and curcin content of J. curcas seeds obtained from Mexico and Madagascar, and conclude that while phorbol esters are lacking in edible seeds, both types contain curcin. We also analyzed spatial distribution of these toxins in seeds. Phorbol-esters were most concentrated in the tegmen. Curcin was found in both the endosperm and tegmen. We conclude that seed toxicity in J. curcas is likely to be due to a monogenic trait, which may be under maternal control. We also conducted AFLP analysis and conclude that genetic diversity is very limited in the Madagascan collection compared to the Mexican collection. Copyright © 2011 Elsevier Masson SAS.

Circadian Clocks for All Meal-Times: Anticipation of 2 Daily Meals in Rats

Science.gov (United States)

Mistlberger, Ralph E.; Kent, Brianne A.; Chan, Sofina; Patton, Danica F.; Weinberg, Alexander; Parfyonov, Maksim

2012-01-01

Anticipation of a daily meal in rats has been conceptualized as a rest-activity rhythm driven by a food-entrained circadian oscillator separate from the pacemaker generating light-dark (LD) entrained rhythms. Rats can also anticipate two daily mealtimes, but whether this involves independently entrained oscillators, one ‘continuously consulted’ clock, cue-dependent non-circadian interval timing or a combination of processes, is unclear. Rats received two daily meals, beginning 3-h (meal 1) and 13-h (meal 2) after lights-on (LD 14∶10). Anticipatory wheel running began 68±8 min prior to meal 1 and 101±9 min prior to meal 2 but neither the duration nor the variability of anticipation bout lengths exhibited the scalar property, a hallmark of interval timing. Meal omission tests in LD and constant dark (DD) did not alter the timing of either bout of anticipation, and anticipation of meal 2 was not altered by a 3-h advance of meal 1. Food anticipatory running in this 2-meal protocol thus does not exhibit properties of interval timing despite the availability of external time cues in LD. Across all days, the two bouts of anticipation were uncorrelated, a result more consistent with two independently entrained oscillators than a single consulted clock. Similar results were obtained for meals scheduled 3-h and 10-h after lights-on, and for a food-bin measure of anticipation. Most rats that showed weak or no anticipation to one or both meals exhibited elevated activity at mealtime during 1 or 2 day food deprivation tests in DD, suggesting covert operation of circadian timing in the absence of anticipatory behavior. A control experiment confirmed that daytime feeding did not shift LD-entrained rhythms, ruling out displaced nocturnal activity as an explanation for daytime activity. The results favor a multiple oscillator basis for 2-meal anticipatory rhythms and provide no evidence for involvement of cue-dependent interval timing. PMID:22355393

The jojoba, Simmondsia chinensis, is a characteristic desert plant native to the Sonoran desert. The jojoba meal after oil extraction is rich in protein. The major jojoba proteins were albumins (79%) and globulins (21%), which have similar amino acid compositions and also showed a labile thrombin-inhibitory activity. SDS-PAGE showed two major proteins at 50 kDa and 25 kDa both in the albumins and in the globulins. The 25 kDa protein has trypsin- and chymotrypsin-inhibitory activities. In vitro digestibility of the globulins and albumins resembled that of casein and soybean protein concentrates and was increased after heat treatment. The increased digestibility achieved by boiling may be attributed to inactivation of the protease inhibitors and denaturation of proteins.

The purpose of this study was to establish a new methodology to remove the toxic compounds present in jojoba meal and flour. Also, to perform the biological evaluation of the detoxified products and to chemically characterize the protein fractions. Jojoba meal and seed without testa were deffated with hexane and detoxified with a 7:3 isopropanol-water mixture which removed 86% of total phenolic compounds and 100% of simmondsins originally present, the resulting products had reduced bitterness and caused no deaths on experimental animals. NPR values obtained for diets containing such products were significantly different from those obtained with the casein control (p less than 0.05). Total protein was made up of three different fractions: the water-soluble fraction was the most abundant (61.8%), followed by the salt-soluble (23.6%), and the alkaline soluble fraction (14.6%). The nitrogen solubility curves showed that the isoelectric point for the water-soluble and salt-soluble fractions was pH 3.0, while that of the alkaline fraction fell in the range of 4.5-5.0. All fractions had a maximum solubility at pH 7.0. The methodology reported here, offers a viable solution to eliminate toxic compounds from jojoba meal or seeds, and upgrades the potential use of products such as animal feed or raw material for the production of protein isolates.

Full Text Available Neem (Azadiracta India seed oil in appropriate amount when smeared on the surface of the hand showed excellent repellent action against Aedes aegypti mosquitoes. When 1 ml of oil was spread on the hand, with an approximate area of 160 sq cm the percentage of alighting and blood fed mosquitoes in the experimental cages varied from 14 to 78 and 4 to 46 respectively. This percentage decreased to 6 to 18 and 0 to 16 respectively when the amount of oil applied was 1.5 ml. Only 0-4% of the mosquitoes alighted on the skin of which 2% only took the blood meal when 2 ml of the oil was used to cover the hand. In the control cages cent percent of the mosquitoes alighted and sucked blood. The repellent action was directly proportional to the hour of exposure to the oil. It was also observed that even after alighting on a oil- smeared skin a sizeable proportion of mosquitoes were not able to imbibe blood meal. Neem seed oil was non-toxic, non- irritating to skin.

This study was designed to assess the relative influence of meal weight and caloric content on gastric emptying of liquid and solid meals in man. A dual radioisotopic method which permits noninvasive and simultaneous measurement of liquid- and solid-phase emptying by external gamma camera techniques was employed. Nine healthy volunteer subjects ingested 50-, 300-, and 900-g lettuce and water meals adjusted to either 68, 208, or 633 kcal with added salad oil. The following observations were made: (1) absolute emptying rates (grams of solid food emptied from the stomach per minute) increased directly and significantly with meal weight; (2) increasing meal total caloric content significantly slowed solid food gastric emptying but did not overcome the enhancing effect of meal weight; and (3) liquid emptying rates were uninfluenced by meal total kcal amount

This study investigates the effects of temperature and pressure on inactivation of myrosinase extracted from black, brown and yellow mustard seeds. Brown mustard had higher myrosinase activity (2.75 un/mL) than black (1.50 un/mL) and yellow mustard (0.63 un/mL). The extent of enzyme inactivation increased with pressure (600-800 MPa) and temperature (30-70 °C) for all the mustard seeds. However, at combinations of lower pressures (200-400 MPa) and high temperatures (60-80 °C), there was less i...

Family meals have been associated with higher diet quality and reduced risk of obesity in children. Observational studies of the family meal have been employed with increasing frequency, yet there is currently no tool available for measuring the healthfulness of food served during the meal. Here we present the development and validation of the Healthy Meal Index (HMI), a novel tool for scoring the healthfulness of foods served to children during a meal, as well as sociodemographic predictors of meal scores. Parents of 233 children, aged 4-8 years, self-recorded three home dinners. A research assistant obtained a list of foods available during the meal (meal report) via phone call on the night of each video-recorded meal. This meal report was coded into component food groups. Subsequently, meals were scored based on the availability of more healthy "Adequacy foods" and the absence of "Moderation foods", (of which reduced consumption is recommended, according to pediatric dietary guidelines). Adjusted linear regression tested the association of sociodemographic characteristics with HMI scores. A validation study was conducted in a separate sample of 133 children with detailed meal data. In adjusted models, female children had higher HMI Moderation scores (p = 0.02), but did not differ in HMI Adequacy or Total scores. Parents with more education served meals with higher HMI Adequacy (p = 0.001) and Total scores (p = 0.001), though no significant difference was seen in HMI Moderation score (p = 0.21). The validation study demonstrated that the HMI was highly correlated with servings of foods and nutrients estimated from observations conducted by research staff. The HMI is a valuable tool for measuring the quality of meals served to children. Copyright © 2016. Published by Elsevier Ltd.

Dehydration-Anorexia Derives From A Reduction In Meal Size, But Not Meal Number

Boyle, Christina N.; Lorenzen, Sarah M.; Compton, Douglas; Watts, Alan G.

2011-01-01

The anorexia that results from extended periods of cellular dehydration is an important physiological adaptation that limits the intake of osmolytes from food and helps maintain the integrity of fluid compartments. The ability to experimentally control both the development and reversal of anorexia, together with the understanding of underlying hormonal and neuropeptidergic signals, make dehydration (DE)-anorexia a powerful model for exploring the interactions of neural networks that stimulate and inhibit food intake. However, it is not known which meal parameters are affected by cellular dehydration to generate anorexia. Here we use continuous and high temporal resolution recording of food and fluid intake, together with a drinking-explicit method of meal pattern analysis to explore which meal parameters are modified during DE-anorexia. We find that the most important factor responsible for DE-anorexia is the failure to maintain feeding behavior once a meal has started, rather than the ability to initiate a meal, which remains virtually intact. This outcome is consistent with increased sensitivity to satiation signals and post-prandial satiety mechanisms. We also find that DE-anorexia significantly disrupts the temporal distribution of meals across the day so that the number of nocturnal meals gradually decreases while diurnal meal number increases. Surprisingly, once DE-anorexia is reversed this temporal redistribution is maintained for at least 4 days after normal food intake has resumed, which may allow increased daily food intake even after normal satiety mechanisms are reinstated. Therefore, DE-anorexia apparently develops from a selective targeting of those neural networks that control meal termination, whereas meal initiation mechanisms remain viable. PMID:21854794

A New Nordic Diet (NND) was developed in the context of the Danish OPUS Study (Optimal well-being, development and health for Danish children through a healthy New Nordic Diet). Health, gastronomic potential, sustainability and Nordic identity were crucial principles of the NND. The aim of the present study was to investigate the effects of serving NND school meals compared with the usual packed lunches on the dietary intake of NND signature foods. For two 3-month periods, 834 Danish children aged 8-11 years received NND school meals or their usual packed lunches brought from home (control) in random order. The entire diet was recorded over 7 consecutive days using a validated Web-based Dietary Assessment Software for Children. The NND resulted in higher intakes during the entire week (% increase) of root vegetables (116 (95 % CI 1·93, 2·42)), cabbage (26 (95 % CI 1·08, 1·47)), legumes (22 (95 % CI 1·06, 1·40)), herbs (175 (95 % CI 2·36, 3·20)), fresh berries (48 (95 % CI 1·13, 1·94)), nuts and seeds (18 (95 % CI 1·02, 1·38)), lean fish and fish products (47 (95 % CI 1·31, 1·66)), fat fish and fish products (18 (95 % CI 1·02, 1·37)) and potatoes (129 (95 % CI 2·05, 2·56)). Furthermore, there was a decrease in the number of children with zero intakes when their habitual packed lunches were replaced by NND school meals. In conclusion, this study showed that the children increased their intake of NND signature foods, and, furthermore, there was a decrease in the number of children with zero intakes of NND signature foods when their habitual packed lunches were replaced by school meals following the NND principles.

Full Text Available In tropical soils with intensive agriculture an increasing sulfur deficiency has been verified in several crops. The low available S in these soils is caused by the continuous use of concentrated NPK fertilizers. The objective of this work was to evaluate the utilization by rice (Oriza sativa L. and crotalaria juncea (Crotalaria juncea L. of sulfur applied to the soil, under greenhouse conditions. Pots with 3 kg of an Argisol (Paleudalf were used to test the isotopic technique with the stable isotope 34S, adding a solution of sodium sulfate labeled with 34S (14.30 ± 0.05 atom % of 34S to the soil (70 mg SO4-S per kg-1 of soil 18 days after sowing both species. The shoots of the crotalaria and rice were harvested, respectively on the 72nd and 122nd days after S fertilization. The concentration and the amount of sulfur in the crotalaria were higher than in rice, due to the higher legume requirement for this nutrient. The sulfur requirement and the short time interval between fertilization and harvest of the crotalaria resulted in a small amount of native SO4-S mineralized in the soil and a small quantity of 34SO4 immobilized by soil microorganisms. Thus, the percentage of sulfur in the crotalaria derived from the fertilizer (Sdff was higher than in the rice (%Sdff crotalaria = 91.3 ± 3.5%; %Sdff rice = 66.3 ± 0.8%. The expressive values of %Sdff indicate a low rate of mineralization of SO4-S probably as a consequence of the low available sulfur content in the soil.

A unifying physiological explanation of the urge to initiate eating is still not available as human hunger in meal-to-meal eating may not be under homeostatic control. We hypothesized that a central circadian and a gastrointestinal ultradian timing mechanism coordinate non-deprivation meal-to-meal eating. We examined hunger as a function of time of day, inter-meal (IM) energy expenditure (EE), and concentrations of proposed hunger-controlling hormones ghrelin, leptin, and insulin. In two crossover studies, 10 postmenopausal women, BMI 23-26 kg/m(2) engaged in exercise (EX) and sedentary (SED) trials. Weight maintenance meals were provided at 6h intervals with an ad libitum meal at 13 h in study 1 and 21 h snack in study 2. EE during IM intervals was measured by indirect calorimetry and included EX EE of 801 kcal in study 1, and 766-1,051 kcal in study 2. Hunger was assessed with a visual analog scale and blood was collected for hormonal determination. Hunger displayed a circadian variation with acrophase at 13 and 19 h and was unrelated to preceding EE. Hunger was suppressed by EX between 10 and 16 h and bore no relationship to either EE during preceding IM intervals or changes in leptin, insulin, and ghrelin; however leptin reflected IM energy changes and ghrelin and insulin, prandial events. During non-deprivation meal-to-meal eating, hunger appears to be under non-homeostatic central circadian control as it is unrelated to EE preceding meals or concentrations of proposed appetite-controlling hormones. Gastrointestinal meal processing appears to intermittently suppress this control and entrain an ultradian hunger pattern. © 2013 Elsevier Inc. All rights reserved.

An audit of 'standard' (STD) and 'energy and protein fortified' (HEHP) meals from Meals on Wheels (MOW) South Australia's summer menu was conducted to evaluate the consistency, and serve size and nutrient contents, of their menu items. Twenty soups, 20 mains and 20 desserts from each of the STD and HEHP menus were prepared at the MOW South Australia's kitchen and delivered to three 'sham(dummy)-clients' over a 5-week period. Each meal component was weighed in triplicate, to the nearest gram, the variation within the serve weight was calculated, and the overall energy and protein content of each meal was determined using FoodWorks (Xyris Software, Highgate Hill, Queensland, Australia). On average, the variability for soups and mains was ≤6% and for desserts was ≤10% and although the measured serve sizes of the MOW meals were consistently smaller than prescribed serve size, the differences were minor. As a percentage of recommended daily intakes (RDIs) for adults aged over 60 years, we calculated that the STD meals contained 21-39% for energy and 42-63% for protein while the HEHP meals contained 29-55% for energy and 46-69% for protein. These findings demonstrate that MOW meals currently meet the voluntary meal guidelines for energy and protein.

The extracts were tested for their insecticidal and repellent properties against the pulse beetles, Callosobruchus chinensis. The extracts from the seeds of A. squamosa recorded l00% mortality of beetles within twenty and four hours of their exposure to methanol and ethanol extracts, respectively. The other extracts that caused high mortality were from A. nilotica, C. juncea, M. communis and S. aegzptiaca in methanol and B. sacra, J. dhofarica, S. aegptiaca and commercial neem in ethanol. Extracts of M. communis in methanol were highly repellent to the beetles compared to other extracts. Legume seeds treated with extracts of A. squamosa were not repellent, rather the beetles were attracted to them.

The aim was to determine the effect of substituting pumpkin seed cake (PSC) or extruded linseed (ELS) for soya bean meal in goats' diets on milk yield, milk composition and fatty acids profile of milk fat. In total, 28 dairy goats were divided into three groups. They were fed with concentrate mixtures containing soya bean meal (Control; n=9), ELS (n=10) or PSC (n=9) as main protein sources in the trial lasting 75 days. Addition of ELS or PSC did not influence milk yield and milk gross composition in contrast to fatty acid profile compared with Control. Supplementation of ELS resulted in greater branched-chain fatty acids (BCFA) and total n-3 fatty acids compared with Control and PSC (PLA, C18:2n-6; 2.10 and 2.28 g/100 g fatty acids, respectively) proportions compared with Control (2.80 g/100 g fatty acids; PLA/ALA ratio (3.81 v. 7.44 or 6.92, respectively; Psoya bean meal with ELS in hay-based diets may increase beneficial n-3 fatty acids and BCFA accompanied by lowering LA/ALA ratio and increased C18:0. Pumpkin seed cake completely substituted soya bean meal in the diet of dairy goats without any decrease in milk production or sharp changes in fatty acid profile that may have a commercial or a human health relevancy.

An 8-week feeding trial was conducted to evaluate the effect of replacing fish meal with pumpkin seed meal (PSM) or phosphorylated protein concentrate of pumpkin seed meal (PPCPS) on growth and metabolic responses of silver catfish. Five isonitrogenous and isocaloric diets were formulated. Control diet contained fish meal as the main protein source. The treatment groups contained 25 and 50% of either PSM or PPCPS protein replaced the fishmeal protein. A total of 400 silver catfish, with initial mean weight of 24 ± 0.46 g, were distributed into 20 tanks. For data four orthogonal contrasts were applied: control diet versus PSM diets; control diets versus PPCPS diets; control versus other diets; PSM diets versus PPCPS diets. The results indicated that the fish fed PSM diets had lower weight gain when compared to either control diet or PPCPS. The PPCPS do not affect growth and protein efficiency ratio. Lower albumin contents were found for the control diet fish for the contrasts control diet versus PPCPS diet and control diet versus other diets. The hepatic ALAT enzyme activity was higher in the fish fed the control diet (P < 0.05). The hepatic ALP was most active in fish that received the PPCPS diets, when comparing control diet versus PPCPS diets and control diet versus other diets. The hepatosomatic index was higher for fish fed the PPCPS. Our results indicated that PPCPS presents relevant nutritional quality for fish and can replace the fish meal protein up to 50% without affecting growth, PER and intermediate metabolites in silver catfish.

When defatted jojoba meal is used as animal food, it causes food-intake reduction and growth retardation. Detoxification procedures by chemical, microbiological, and solvent extraction methods are reported by several authors. Here we report a successful detoxification of jojoba meal using enzymes. We establish reaction conditions that yield new meal which has the same nutritional qualities in proteins as the original meal. The enzymatic reaction gives rise to one major compound to which the structure of an amide is assigned on the basis of IR, 1H and 13C NMR spectra. The effect of the resulting jojoba meal on the food intake in rats is checked. In contrast, the detoxified meal containing the amide derivatives shows no toxicological activity since rats receiving oral administration of the obtained meal show normal growth. Thus, it is expected that this meal could be used as an animal feed ingredient.

2005-11-01

Previous studies have demonstrated an inverse association between meal frequency and the prevalence of obesity in adulthood. The aim of this study was to assess the relationship between meal frequency and childhood obesity. Stature and weight of 4,370 German children ages 5 to 6 years were determined in six Bavarian (Germany) public health offices during the obligatory school entry health examination in 2001/2002. An extensive questionnaire on risk factors for obesity was answered by their parents. Obesity was defined according to sex- and age-specific BMI cut-off points proposed by the International Obesity Task Force. The main exposure was daily meal frequency. The prevalence of obesity decreased by number of daily meals: three or fewer meals, 4.2% [95% confidence interval (CI), 2.8 to 6.1]; four meals, 2.8% (95% CI, 2.1 to 3.7); and 5 or more meals, 1.7% (95% CI, 1.2 to 2.4). These effects could not be explained by confounding due to a wide range of constitutional, sociodemographic, and lifestyle factors. The adjusted odds ratios for obesity were 0.73 (95% CI, 0.44 to 1.21) for four meals and 0.51 (95% CI, 0.29 to 0.89) for five or more meals. Additional analyses pointed to a higher energy intake in nibblers compared with gorgers. A protective effect of an increased daily meal frequency on obesity in children was observed and appeared to be independent of other risk factors for childhood obesity. A modulation of the response of hormones such as insulin might be instrumental.

A greenhouse study was carried out with Brassica juncea to critically evaluate effects of bacterial inoculation on the uptake of heavy metals from Pb-Zn mine tailings by plants. Application of plant growth-promoting rhizobacteria, including nitrogen-fixing bacteria and phosphate and potassium solubilizers, might play an important role in the further development of phytoremediation techniques. The presence of these beneficial bacteria stimulated plant growth and protected the plant from metal toxicity. Inoculation with rhizobacteria had little influence on the metal concentrations in plant tissues, but produced a much larger above-ground biomass and altered metal bioavailability in the soil. As a consequence, higher efficiency of phytoextraction was obtained compared with control treatments. - Rhizobacteria promoted growth above normal biomass, but did not influence plant metal concentrations

Pulses are low-glycemic appetite-suppressing foods, but it is not known whether these properties persist after being consumed as part of a meal and after a second meal. The objective of this study was to determine the effects of a fixed-size pulse meal on appetite and blood glucose (BG) before and after an ad libitum test meal (pizza) and on food intake (FI) at the test meal. Males (n = 25; 21.3 ± 0.5 years; 21.6 ± 0.3 kg·m(-2)) randomly consumed 4 isocaloric meals: chickpea; lentil; yellow split pea; and macaroni and cheese (control). Commercially available canned pulses provided 250 kcal, and were consumed with macaroni and tomato sauce. FI was measured at a pizza meal 260 min after consumption of the isocaloric meal. BG and appetite were measured from 0 to 340 min. The lentil and yellow pea, but not chickpea, treatments led to lower appetite ratings during the 260 min prepizza meal period, and less FI at the pizza meal, compared with macaroni and cheese (p effect of treatment on prepizza meal BG AUC (p = 0.07). Immediately after the pizza meal, BG was lower following the chickpea and lentil treatments, but not the yellow pea treatment (p effects of consuming a pulse meal on appetite, FI at a later meal, and the BG response to a later meal are dependent on pulse type.

Full Text Available The transcription factors FLOWERING LOCUS C (FLC and SHORT VEGETATIVE PHASE (SVP can interact to form homologous and heterologous protein complexes that regulate flowering time in Brassica juncea Coss. (Mustard.Previous studies showed that protein interactions were mediated by the K domain, which contains the subdomains K1, K2 and K3. However, it remains unknown how the subdomains mediate the interactions between FLC and SVP. In the present study, we constructed several mutants of subdomains K1–K3 and investigated the mechanisms involved in the heterologous interaction of BjFLC/BjSVP and in the homologous interaction of BjFLC/BjFLC or BjSVP/BjSVP. Yeast two-hybrid and β-Galactosidase activity assays showed that the 19 amino acids of the K1 subdomain in BjSVP and the 17 amino acids of the K1 subdomain in BjFLC were functional subdomains that interact with each other to mediate hetero-dimerization. The heterologous interaction was enhanced by the K2 subdomain of BjSVP protein, but weakened by its interhelical domain L2. The heterologous interaction was also enhanced by the K2 subdomain of BjFLC protein, but weakened by its K3 subdomain. The homologous interaction of BjSVP was mediated by the full K-domain. However, the homologous interaction of BjFLC was regulated only by its K1 and weakened by its K2 and K3 subdomains. The results provided new insights into the interactions between FLC and SVP, which will be valuable for further studies on the molecular regulation mechanisms of the regulation of flowering time in B. juncea and other Brassicaceae.

An audit of ‘standard’ (STD) and ‘energy and protein fortified’ (HEHP) meals from Meals on Wheels (MOW) South Australia’s summer menu was conducted to evaluate the consistency, and serve size and nutrient contents, of their menu items. Twenty soups, 20 mains and 20 desserts from each of the STD and HEHP menus were prepared at the MOW South Australia’s kitchen and delivered to three ‘sham(dummy)-clients’ over a 5-week period. Each meal component was weighed in triplicate, to the nearest gram, the variation within the serve weight was calculated, and the overall energy and protein content of each meal was determined using FoodWorks (Xyris Software, Highgate Hill, Queensland, Australia). On average, the variability for soups and mains was ≤6% and for desserts was ≤10% and although the measured serve sizes of the MOW meals were consistently smaller than prescribed serve size, the differences were minor. As a percentage of recommended daily intakes (RDIs) for adults aged over 60 years, we calculated that the STD meals contained 21–39% for energy and 42–63% for protein while the HEHP meals contained 29–55% for energy and 46–69% for protein. These findings demonstrate that MOW meals currently meet the voluntary meal guidelines for energy and protein. PMID:29461476

Full Text Available An audit of ‘standard’ (STD and ‘energy and protein fortified’ (HEHP meals from Meals on Wheels (MOW South Australia’s summer menu was conducted to evaluate the consistency, and serve size and nutrient contents, of their menu items. Twenty soups, 20 mains and 20 desserts from each of the STD and HEHP menus were prepared at the MOW South Australia’s kitchen and delivered to three ‘sham(dummy-clients’ over a 5-week period. Each meal component was weighed in triplicate, to the nearest gram, the variation within the serve weight was calculated, and the overall energy and protein content of each meal was determined using FoodWorks (Xyris Software, Highgate Hill, Queensland, Australia.

Full Text Available Considering that annatto seeds are rich in protein, the present work aimed to evaluate the biological quality of this nutrient in the meal residue originating from annatto seed processing. We determined the general composition, mineral levels, amino acid composition and chemical scores, antinutritional factors, and protein quality using biological assays. The following values were obtained: 11.50% protein, 6.74% moisture, 5.22% ash, 2.22% lipids, 42.19% total carbohydrates and 28.45% fiber. The residue proved to be a food rich in fiber and also a protein source. Antinutritional factors were not detected. The most abundant amino acids were lysine, phenylalanine + tyrosine, leucine and isoleucine. Valine was the most limiting amino acid (chemical score 0.22. The protein quality of the seed residue and the isolated protein showed no significant differences. The biological value was lower than that of the control protein but higher than that found in other vegetables. Among the biochemical analyses, only creatinine level was decreased in the two test groups compared to the control group. Enzyme tests did not indicate liver toxicity. The results showed favorable aspects for the use of annatto seed residue in the human diet, meriting further research.

The current study aims to investigate the antioxidant activities of various extracts from defatted adlay seed meal (DASM) based on the oxygen radical absorbance capacity (ORAC) assay, peroxyl radical scavenging capacity (PSC) assay and cellular antioxidant activity (CAA) assay. Of all the fractions, the n-butanol fraction exhibited the highest antioxidant activity, followed by crude acetone extract and aqueous fractions. Of the three sub-fractions obtained by Sephadex LH-20 chromatography, sub-fraction 3 possessed the highest antioxidant activity and total phenolic content. There was a strong positive correlation between the total phenolic content and the antioxidant activity. Based on HPLC-DAD-ESI-MS/MS analysis, the most abundant phenolic acid in sub-fraction 3 of DASM was ferulic acid at 67.28 mg/g, whereas the predominant flavonoid was rutin at 41.11 mg/g. Of the major individual compounds in sub-fraction 3, p-coumaric acid exhibited the highest ORAC values, and quercetin exhibited the highest PSC values and CAA values. Copyright © 2015 Elsevier Ltd.

2004-03-10

A mixture of lysophosphatidylcholine (LPC) and phosphatidylcholine (PC) has been isolated by column chromatography from a jojoba meal (Simmondsia chinensis) extract. The molecular species of both classes could be separated and isolated by C18 reversed phase HPLC. The two major compounds were identified by 1D and 2D (1)H and (13)C NMR, by MS, and by GC-MS as 1-oleoyl-3-lysophosphatidylcholine and 1,2-dioleoyl-3-phosphatidylcholine. Eight other molecular species of LPC and four other molecular species of PC could be assigned by comparison of the mass spectra of the isolated compounds with the spectra of the two major compounds. Complete characterization of the individual molecular species was achieved by GC and GC-MS analysis of the fatty acyl composition from the isolated compounds. The PC/LPC proportion in the phospholipid mixture from three different samples is 1.6 +/- 0.1. LPC is considered to be an important bioactive compound; the results of this study suggest further research for the evaluation of potential health benefits of jojoba meal phospholipids.

Smeets, Astrid J; Westerterp-Plantenga, Margriet S

A gorging pattern of food intake has been shown to enhance lipogenesis and increase body weight, which may be due to large fluctuations in storage and mobilisation of nutrients. In a state of energy balance, increasing meal frequency, and thereby decreasing inter-meal interval, may prevent large metabolic fluctuations. Our aim was to study the effect of the inter-meal interval by dividing energy intake over two or three meals on energy expenditure, substrate oxidation and 24 h satiety, in healthy, normal-weight women in a state of energy balance. The study was a randomised crossover design with two experimental conditions. During the two experimental conditions subjects (fourteen normal-weight women, aged 24.4 (SD 7.1) years, underwent 36 h sessions in energy balance in a respiration chamber for measurements of energy expenditure and substrate oxidation. The subjects were given two (breakfast, dinner) or three (breakfast, lunch, dinner) meals per d. We chose to omit lunch in the two meals condition, because this resulted in a marked difference in inter-meal-interval after breakfast (8.5 h v. 4 h). Eating three meals compared with two meals had no effects on 24 h energy expenditure, diet-induced thermogenesis, activity-induced energy expenditure and sleeping metabolic rate. Eating three meals compared with two meals increased 24 h fat oxidation, but decreased the amount of fat oxidised from the breakfast. The same amount of energy divided over three meals compared with over two meals increased satiety feelings over 24 h. In healthy, normal-weight women, decreasing the inter-meal interval sustains satiety, particularly during the day, and sustains fat oxidation, particularly during the night.

Glycemic index (GI) testing is normally based on individual foods, whereas GIs for meals or diets are based on a formula using a weighted sum of the constituents. The accuracy with which the formula can predict a meal or diet GI is questionable. Our objective was to compare the GI of meals, obtained by using the formula and by using both measured food GI and published values, with directly measured meal GIs. The GIs of 7 foods were tested in 30 healthy people. The foods were combined into 3 meals, each of which provided 50 g available carbohydrate, including a staple (potato, rice, or spaghetti), vegetables, sauce, and pan-fried chicken. The mean (95% CI) meal GIs determined from individual food GI values and by direct measurement were as follows: potato meal [predicted, 63 (56, 70); measured, 53 (46, 62)], rice meal [predicted, 51 (45, 56); measured, 38 (33, 45)], and spaghetti meal [predicted, 54 (49, 60); measured, 38 (33, 44)]. The predicted meal GIs were all higher than the measured GIs (P < 0.001). The extent of the overestimation depended on the particular food, ie, 12, 15, and 19 GI units (or 22%, 40%, and 50%) for the potato, rice, and spaghetti meals, respectively. The formula overestimated the GI of the meals by between 22% and 50%. The use of published food values also overestimated the measured meal GIs. Investigators using the formula to calculate a meal or diet GI should be aware of limitations in the method. This trial is registered with the Australian and New Zealand Clinical Trials Registry as ACTRN12611000210976.

Full Text Available Two feeding experiments have been conducted to test the different sources of soybean meal (local, India, USA and the partial substitution with peanut meal (10%, rapeseed meal (5% and fish meal (5% in the diet for broiler. The first feeding experiment was carried out on broiler starter for 4 weeks in wire cages . Twelve rations in factorial design (3 x 4 were conducted using 6 birds/cage and replicated 6 times . Birds fed India soybean meal had significantly less body weight (1,000 g than those fed local or USA soybean meals (1,037 and 1,023 g, respectively . Partial substitution with peanut, rapeseed or fish meal did not affect body weight, feed consumption or feed/gain ratio . The average consumption and feed/gain were 1,535 g and 1,569, respectively . In second experiment, one thousand five hundred broiler chicks were allocated in 6 dietary treatments in factorial design (3 x 2 . Factor one was different sources of soybean meal (local, India and USA and factor two was the inclusion of peanut meal at 0 and 10%. Birds were kept on litter system for 6 weeks . Each treatment used 5 replicates and 50 birds/replicate . The results show no effect of the treatment to any parameter measured . Body weight of bird fed local, India and USA soybean meal were 1,662, 1,641 and 1,669 g and feed/gain were 2 .043, 2 .051 and 2.035, respectively . Cost analysis indicates that ration uses local soybean meal gives a higher cost than those of India and USA soybean meals.

Effective strategies to increase dietary intake in older persons with a poor appetite are needed. Previous studies have shown that increasing diet variety may increase dietary intake. This has not been tested in older adults with a poor appetite. We investigated if an increased variety of foods within a cooked meal results in a higher meal energy intake in older women with a poor appetite. This study was a randomized, controlled, cross-over trial among 19 older (>65 years) women with a poor appetite. Two cooked meals of similar weight and energy density (except starch) were served under standardized conditions on two weekdays: a test meal consisting of three different varieties of vegetables, meat or fish, and starch components, and a control meal without variety. Participants ate ad libitum and the actual consumed amounts and their nutritional content were calculated. Data were analyzed by mixed linear models. Average intake in energy was 427 kcal (SD 119) for the test meal with variety and 341 kcal (SD 115) for the control meal without variety. This resulted in a statistically significant (for period effects adjusted) mean difference of 79 kcal (95% CI = 25-134). Total meal intake in grams was also higher for the test meal with variety (48 g, 95% CI = 1-97) but protein intake (g) was not (3.7 g, 95% CI = -1.4 to 8.8). This was consistent for all meal components except starch and within each component three varieties were consumed equally. The results of the present study suggest that increasing meal variety may be an effective strategy to increase energy intake in older adults with a poor appetite. Copyright © 2015 Elsevier Ltd.

Full Text Available The objective this work was to evaluate the technical and economic viability of the substitution level of soybean meal by babassu meal in rations to broiler from 22 to 42 days old. It was used 80 male broiler chicks at one day of age, distributed into complete random designs with four treatments (0, 10, 20 e 30% substituition of soybean meal by babassu meal and five repetitions of four broilers each. Were evaluated the performance (weight dain, feed intake and feed conversion, carcass and cuts, organ biometry, feed cost per kilogram body weight and gross margin. To verify the relationship of cost of replacing soybean meal with pie babassu, inequalities were established. The substitution level of soybean meal by babassu meal had no influence (P>0,05 any of the performance characteristics, wich showed the technical viability of substituting up to 30%. Similarly, there was no affect on carcass yield, cuts weight and organ biometry. The cust less with feed per kg for chicken produced and the higher gross margin were obtained from chickens fed diets with 0% babassu meal. The increased of substitution level soybean meal by babassu meal in ration for broilers from 22 to 42 days old proved unviable economically, however, the inequalities produced can be useful in practical situations.

The present study was conducted to determine the change of digestive physiology in sea cucumber Apostichopus japonicus (Selenka) induced by corn kernels meal and soybean meal in diets. Four experimental diets were tested, in which Sargassum thunbergii was proportionally replaced by the mixture of corn kernels meal and soybean meal. The growth performance, body composition and intestinal digestive enzyme activities in A. japonicus fed these 4 diets were examined. Results showed that the sea cucumber exhibited the maximum growth rate when 20% of S. thunbergii in the diet was replaced by corn kernels meal and soybean meal, while 40% of S. thunbergii in the diet can be replaced by the mixture of corn kernels meal and soybean meal without adversely affecting growth performance of A. japonicus. The activities of intestinal trypsin and amylase in A. japonicus can be significantly altered by corn kernels meal and soybean meal in diets. Trypsin activity in the intestine of A. japonicus significantly increased in the treatment groups compared to the control, suggesting that the supplement of corn kernels meal and soybean meal in the diets might increase the intestinal trypsin activity of A. japonicus. However, amylase activity in the intestine of A. japonicus remarkably decreased with the increasing replacement level of S. thunbergii by the mixture of corn kernels meal and soybean meal, suggesting that supplement of corn kernels meal and soybean meal in the diets might decrease the intestinal amylase activity of A. japonicus.

The aim of this study was to verify the in vivo effectiveness of pumpkin seed (Curcubita pepo Linnaeus, 1753) in naturally infected ostriches in the Cariri zone, semiarid region of Paraíba State, Brazil. Forty-eight ostriches were used, African Black breed, of 14 to 36 months old, naturally infected by gastrointestinal nematodes. These animals were divided into four groups of 12 ostriches. Group 1 consists of animals treated with 0.5 g/kg live weight (l. w.) of pumpkin seed meal; group 2 received 1 g/kg l. w. of pumpkin seed meal; group 3 was treated with Albendazole 5 %, at the dosage of 1 mL/10 kg l. w.; and Group 4 was the control group and do not received treatment. Groups 1 and 2 received the treatment for three consecutive days, orally, at intervals of 7 days, totaling nine administrations. The Albendazole 5 % was administered one time, at the beginning of the experiment, according to the manufacturer's recommendations. The groups treated with pumpkin seed showed a significant decrease in egg counts per gram of feces (EPG), wherein group 2 (1 g/kg l. w.) was the most effective. The control and drug groups showed no reduction in EPG. The results of the present study demonstrate that the administration of pumpkin seed was effective in controlling gastrointestinal helminths in naturally infected ostriches.

Full Text Available This research aimed to study the carcass characteristics of Kacang goats fed ration containing kapok seed meal (KSM as a component of the concentrate. The experiment was conducted in two stages. The first stage was to find out the best variety of kapok that will be used in the second experiment; the second stage was to determine the benefits of KSM on carcass characteristics. Twenty-five, 8 months old Kacang goats with initial body weight of 11.71±1.08 kg, were used in this experiment. The animals were housed individually based on completely randomized design (CRD with 5 treatments and 5 replications. The rations were based on forage:concentrate ratio of 50:50 dry matter basis. The ration contained concentrates, with increasing levels of KSM, i.e.: R0 (napier grass + concentrate: rice bran, coconut cake, corn, urea + 0% KSM; R5 (R0 + KSM 5%; R10 (R0 + KSM 10%; R15 (R0 + KSM 15%; and R20 (R0 + KSM 20%. Drinking water was provided ad libitum. The result of first stage showed that KSM variety of MH-1 would be used as a component of the concentrate on the second experiment. The increasing level of KSM in the rations had significant effect (P<0.05 on physical characteristics of the carcass, such as dressing percentage (44.35%, carcass length (54.006 cm, fleshing index (130.59 g/cm, plumpness of leg (87.48%, loin eye area (5.06 cm2, and percentage of carcass meat (64.69%. It is concluded that MH-1 variety of KSM can be used as a feed component up to 20 % in the goat ration.

School meals are also a teaching occasion in which children learn about food and meals, which is referred to as "pedagogic meals" in Sweden. The aim of the present article was to study how the pedagogic meal is practiced in preschool and school settings, with focus on how teachers acted when interacting with the children. Observations, interviews, and focus group interviews. School canteens. Three schools. Teaching in the school meal situation. Social constructionism, new social studies of childhood. The teachers took on 3 different roles. The sociable teacher role entailed turning the school lunch into a social occasion, the educating teacher role involved educating the children, and the evasive teacher role was not associated with the definition of a pedagogic meal. The teacher roles, which ranged from adult-oriented to child-oriented, and which varied in the level of interaction with the children, were summarized in a framework named the Adult- to Child-oriented Teacher Role Framework for School Meals (ACTS). To realize the potential of pedagogic meals, teachers must be educated and become aware of the effects of their behaviors. In this situation, the ACTS framework can constitute a useful tool.

Patients recently discharged from the hospital are vulnerable and are at high risk for readmission. Home-delivered meals may be beneficial in improving their health and facilitating independent living in the community. The purpose of this study was to identify the association between home-delivered meals and use of hospital services. This study includes 120 clients recently discharged from an inpatient hospital stay or from an emergency department (ED) visit who received meal services from Meals On Wheels, Inc., of Tarrant County. Healthcare utilization data was extracted from the Dallas-Fort Worth Hospital Council Foundation, a regional all claims database used by over 90% of hospitals in Dallas-Fort Worth area. Signed tests and generalized linear models (GLM) were performed. A total of 16,959 meals were delivered from March 2013 through March 2014. Each client received an average of 6.19 meals per week. The average number of ED visits decreased from 5.03 before receipt of meals to 1.45 after receipt of meals, z = -5.23, p meals were less likely to experience ED visits and hospitalizations after controlling for demographic characteristics and levels of physical functioning. The findings of this study indicate that home-delivered meals services may contribute to a reduction in hospital based care services among frail and vulnerable adults. Additional studies should consider the short and long-term effects of home-delivered meals services on healthcare utilization and the potential to decrease healthcare costs.

The addition of locust bean gum but not water delayed the gastric emptying rate of a nutrient semisolid meal in healthy subjects

2003-06-01

Full Text Available Abstract Background Most of the previous studies regarding the effects of gel-forming fibres have considered the gastric emptying of liquid or solid meals after the addition of pectin or guar gum. The influence of locust bean gum, on gastric emptying of nutrient semisolid meals in humans has been less well studied, despite its common occurrence in foods. Using a standardised ultrasound method, this study was aimed at investigating if the gastric emptying in healthy subjects could be influenced by adding locust been gum, a widely used thickening agent, or water directly into a nutrient semisolid test meal. Methods The viscosity of a basic test meal (300 g rice pudding, 330 kcal was increased by adding Nestargel (6 g, 2.4 kcal, containing viscous dietary fibres (96.5% provided as seed flour of locust bean gum, and decreased by adding 100 ml of water. Gastric emptying of these three test meals were evaluated in fifteen healthy non-smoking volunteers, using ultrasound measurements of the gastric antral area to estimate the gastric emptying rate (GER. Results The median value of GER with the basic test meal (rice pudding was estimated at 63 %, (range 47 to 84 %, (the first quartile = 61 %, the third quartile = 69 %. Increasing the viscosity of the rice pudding by adding Nestargel, resulted in significantly lower gastric emptying rates (p p = 0.28 compared to the GER of the basic test meal. Conclusions We conclude that the addition of locust bean gum to a nutrient semisolid meal has a major impact on gastric emptying by delaying the emptying rate, but that the addition of water to this test meal has no influence on gastric emptying in healthy subjects.

Impossible meals? The food and meal situation of flight attendants in Scandinavia - A qualitative interview study.

Science.gov (United States)

Nyberg, Maria; Lennernäs Wiklund, Maria

2017-06-01

The working conditions of flight attendants (FAs) often involve extended and irregular working hours, short rest periods, difficulties in planning for breaks and high demands of service provision. Moreover, work schedules including early check-in, shifts during circadian low and time-zone transitions imply constant exposure to alterations in circadian systems and related health risks. The aim of this explorative study was to investigate how the organisation of work, time and place influence the food and meal situation of FAs when at work, focusing on patterns, form and social context of meals. The research questions posed were how food and meals at work were characterised and perceived among the FAs, and what strategies were adopted to manage the food and meal situation. Qualitative, semi-structured interviews were conducted with fourteen FAs working in Scandinavia. The results indicated that the organisation of work, time and place have a major influence on the meal situation at work, and how food and meals are perceived and managed by FAs. The work was defined as fragmented and inconsistent regarding time and place resulting in scattered meals and a more snack-based form of eating. The meal situation was characterised by irregularity as well as unpredictability. Eating took place when food was available and when there was enough time to eat, rather than being guided by hunger or social context. Various strategies such as eating in prevention, using emergency food, avoiding certain food and drinks or eating little or nothing at all were used to manage the unpredictability of the meal situation as well as the gap between organisational and individual times. The findings demonstrated the individual responsibility to solve the meal at work, e.g. to solve organisational times. Copyright © 2017 Elsevier Ltd. All rights reserved.

Engineering low phorbol ester Jatropha curcas seed by intercepting casbene biosynthesis.

Casbene is a precursor to phorbol esters and down-regulating casbene synthase effectively reduces phorbol ester biosynthesis. Seed-specific reduction of phorbol ester (PE) helps develop Jatropha seed cake for animal nutrition. Phorbol esters (PEs) are diterpenoids present in some Euphorbiaceae family members like Jatropha curcas L. (Jatropha), a tropical shrub yielding high-quality oil suitable as feedstock for biodiesel and bio jet fuel. Jatropha seed contains up to 40 % of oil and can produce oil together with cake containing high-quality proteins. However, skin-irritating and cancer-promoting PEs make Jatropha cake meal unsuitable for animal nutrition and also raise some safety and environmental concerns on its planting and processing. Two casbene synthase gene (JcCASA163 and JcCASD168) homologues were cloned from Jatropha genome and both genes were highly expressed during seed development. In vitro functional analysis proved casbene synthase activity of JcCASA163 in converting geranylgeranyl diphosphate into casbene which has been speculated to be the precursor to PEs. A seed-specific promoter driving inverted repeats for RNAi interference targeting at either JcCASA163 or both genes could effectively down-regulate casbene synthase gene expression with concurrent marked reduction of PE level (by as much as 85 %) in seeds with no pleiotropic effects observed. Such engineered low PE in seed was heritable and co-segregated with the transgene. Our work implicated casbene synthase in Jatropha PE biosynthesis and provided evidence for casbene being the precursor for PEs. The success in reducing seed PE content through down-regulation of casbene synthase demonstrates the feasibility of intercepting PE biosynthesis in Jatropha seed to help address safety concerns on Jatropha plantation and seed processing and facilitate use of its seed protein for animal nutrition.

Mind over platter: pre-meal planning and the control of meal size in humans.

Science.gov (United States)

Brunstrom, J M

2014-07-01

It is widely accepted that meal size is governed by psychological and physiological processes that generate fullness towards the end of a meal. However, observations of natural eating behaviour suggest that this preoccupation with within-meal events may be misplaced and that the role of immediate post-ingestive feedback (for example, gastric stretch) has been overstated. This review considers the proposition that the locus of control is more likely to be expressed in decisions about portion size, before a meal begins. Consistent with this idea, we have discovered that people are extremely adept at estimating the 'expected satiety' and 'expected satiation' of different foods. These expectations are learned over time and they are highly correlated with the number of calories that end up on our plate. Indeed, across a range of foods, the large variation in expected satiety/satiation may be a more important determinant of meal size than relatively subtle differences in palatability. Building on related advances, it would also appear that memory for portion size has an important role in generating satiety after a meal has been consumed. Together, these findings expose the importance of planning and episodic memory in the control of appetite and food intake in humans.

To develop a content validated set of indicators to evaluate the quality of meals and meal service in residential facilities for elderly. Inadequate food intake is an important risk factor for malnutrition in residential facilities for elderly. Through better meeting the needs and preferences of residents and optimization of meals and meal service, residents' food intake can improve. No indicators were available which could help to guide strategies to improve the quality of meals and meal service. The indicator set was developed according to the Indicator Development Manual of the Dutch Institute for Health Care Improvement (CBO). The working group consisted of three nurse researchers and one expert in gastrology and had expertise in elderly care, malnutrition, indicator development, and food quality. A preliminary list of potential indicators was compiled using the literature and the working group's expertise. Criteria necessary to measure the indicator in practice were developed for each potential indicator. In a double Delphi procedure, the list of potential indicators and respective criteria were analyzed for content validity, using a multidisciplinary expert panel of 11 experts in elderly meal care. A preliminary list of 20 quality indicators, including 45 criteria, was submitted to the expert panel in a double Delphi procedure. After the second Delphi round, 13 indicators and 25 criteria were accepted as having content validity. The content validity index (CVI) ranged from 0.83 to 1. The indicator set consisted of six structural, four result, and three outcome indicators covering the quality domains food, service and choice, as well as nutritional screening. The criteria measure diverse aspects of meal care which are part of the responsibility of kitchen staff and health care professionals. The 'quality of meals and meal service' set of indicators is a resource to map meal quality in residential facilities for elderly. As soon as feasibility tests in practice

Full Text Available Las especies de mostaza del género Brassica representan uno de los cultivos de semillas oleaginosas más importantes en India, sin embargo, su diversidad genética es poco conocida. Para la utilización de genotipos en programas de cultivos resulta esencial un mayor conocimiento sobre este tema. Debido a ello, se evaluó la diversidad genética entre 44 genotipos de mostaza de la India Brassica juncea incluyendo variedades y líneas puras de diferentes zonas agro-climáticas de la India y algunos genotipos exóticos Australia, Polonia y China. Para ello, se utilizaron marcadores SSR específicos del genoma A y B y datos fenotípicos del rendimiento de 12 cosechas y sus características. De los 143 primers evaluados, 134 reportaron polimorfismo y un total de 355 alelos fueron amplificados. Se generaron dendrogramas a partir de los coeficientes de similitud de Jaccard y de disimilitud Manhattan, basados en un algoritmo de vinculación promedio UPGMA. Se utilizaron datos de marcadores genéticos y datos fenotípicos. Los genotipos se agruparon en cuatro grupos basados en las distancias genéticas. Ambos patrones de agrupamiento, tanto los basados en los coeficientes de similitud de Jaccard como los basados en los de disimilitud Manhattan, separaron independientemente los genotipos por su genealogía y origen, de una manera efectiva. El PCoA reveló que la agrupación de genotipos basada en datos de marcadores SSR, es más convincente que los datos fenotípicos, sin embargo, se observó que la correlación entre las matrices de distancia fenotípica y genética resultó muy baja r=0.11. Por lo tanto, para estudios de diversidad basados en marcadores moleculares es necesario realizar más pruebas. Los marcadores SSR constituyen herramientas más eficientes para discriminar entre genotipos de B. juncea, que las características cuantitativas.

The Indian meal moth, Plodia interpunctella (Hübner), and Angoumois grain moth, Sitotroga cerealella (Olivier), are two globally distributed stored-grain pests. Laboratory experiments were conducted to examine the impact that corn (Zea mays L.) kernels (i.e., grain) of some Bacillus thuringiensis Berliner (Bt) corn hybrids containing CrylAb Bt delta-endotoxin have on life history attributes of Indian meal moth and Angoumois grain moth. Stored grain is at risk to damage from Indian meal moth and Angoumois grain moth; therefore, Bt corn may provide a means of protecting this commodity from damage. Thus, the objective of this research was to quantify the effects of transgenic corn seed containing CrylAb delta-endotoxin on Indian meal moth and Angoumois grain moth survival, fecundity, and duration of development. Experiments with Bt grain, non-Bt isolines, and non-Bt grain were conducted in environmental chambers at 27 +/- 1 degrees C and > or = 60% RH in continuous dark. Fifty eggs were placed in ventilated pint jars containing 170 g of cracked or whole corn for the Indian meal moth and Angoumois grain moth, respectively. Emergence and fecundity were observed for 5 wk. Emergence and fecundity of Indian meal moth and emergence of Angoumois grain moth were significantly lower for individuals reared on P33V08 and N6800Bt, MON 810 and Bt-11 transformed hybrids, respectively, than on their non-Bt transformed isolines. Longer developmental times were observed for Indian meal moth reared on P33V08 and N6800Bt than their non-Bt-transformed isolines. These results indicate that MON 810 and Bt-11 CrylAb delta-endotoxin-containing kernels reduce laboratory populations of Indian meal moth and Angoumois grain moth. Thus, storing Bt-transformed grain is a management tactic that warrants bin scale testing and may effectively reduce Indian meal moth and Angoumois grain moth populations in grain without application of synthetic chemicals or pesticides.

One hundred fifty Anak and 120 Nigerian heavy local ecotype (NHLE) chickens were used to study the effects of feeding graded levels of mango seed kernel meal (MKM) replacing maize diet on growth traits and haematological parameters. A 2 × 5 factorial arrangement was employed: two breeds and five diets. The birds were randomly allocated to five finisher diets formulated such that MKM replaced maize at 0, 10, 20, 30 and 40% (T1, T2, T3, T4 and T5) inclusion levels, respectively. The effect of breed and dietary treatments on growth performance and blood characteristics were determined. The results showed a significant (P  0.05) when the breeds and treatments were compared. It was concluded that inclusion of dietary MKM below 30% could replace maize in the diets of Anak and NHLE growing chickens without adverse effect on growth performance and blood constituents. This work suggests that genetic differences exist in growth traits of these breeds of chickens. This advantage could be useful in breed improvement programmes and better feeding managements of the NHLE and Anak chickens.

Kenaf is one of the important commercial fiber crops worldwide and defatted kenaf seed meal (DKSM) is a secondary by-product from the kenaf industry. Thus, efforts to turn this low-cost agricultural waste into value-added functional food ingredients will definitely bring advantageous impacts to the community health, environment and economy. The present study was aimed to investigate the cardioprotective properties of DKSM and its phenolics-saponins rich extract (PSRE) in diet-induced hypercholesterolemic rat model. Hypercholesterolemia was induced in Sprague-Dawley rats via atherogenic diet feeding and dietary interventions were conducted by incorporating DKSM (15% and 30%) and equivalent levels of PSRE (2.3% and 4.6%, respectively, equivalent to the total content of phenolics and saponins in DKSM groups) into the atherogenic diets. After 10 weeks of DKSM and PSRE supplementation, the hepatosomatic index, hepatosteatosis, serum lipid profile, Castelli risk indexes as well as hepatic and renal functions of hypercholesterolemic rats were significantly improved (p 0.05), but superiorly upregulated by PSRE (p < 0.05). The combined results showed that hypercholesterolemia and the atherogenic risk in rats were effectively attenuated by DKSM and PSRE supplementation, possibly via modulations of multiple vital processes in hepatic cholesterol metabolism. Furthermore, phenolics and saponins may be the bioactives conferring DKSM and PSRE with their anti-hypercholesterolemic properties. In conclusion, DKSM and PSRE are prospective cardioprotective functional food ingredients for hypercholesterolemic individuals.

Targeting consumers who consume lunches at their worksite cafeterias would be a valuable approach to reduce sodium intake in South Korea. To assess the relationships between socio-demographic factors, consumer satisfaction, attitudes, barriers and the frequency of sodium-reduced meal intake. We implemented a cross-sectional research, analyzing data from 738 consumers aged 18 years or older (327 males and 411 females) at 17 worksite cafeterias in South Korea. We used the ordinary least squares regression analysis to determine the factors related to overall satisfaction with sodium-reduced meal. General linear models with LSD tests were employed to examine the variables that differed by the frequency of sodium-reduced meal intake. Most subjects always or usually consumed the sodium-reduced meal (49%), followed by sometimes (34%) and rarely or never (18%). Diverse menus, taste and belief in the helpfulness of the sodium-reduced meal significantly increased overall satisfaction with the sodium-reduced diet (P < 0.05). We found importance of needs in the following order: 1) 'menu diversity' (4.01 points), 2) 'active promotion' (3.97 points), 3) 'display of nutrition labels in a visible location' (3.96 points), 4) 'improvement of taste' (3.88 points), and 5) 'education of sodium-reduction self-care behaviors' (3.82 points). Dietitians could lead consumers to choose sodium-reduced meals by improving their taste and providing diverse menus for the sodium-reduced meals at worksite cafeterias.

Schmandt, J. (Editor)

1977-01-01

The NASA Meal System was developed with three simple concepts in mind: (1) nutritious, conventional foods are packaged in single-serving units and assembled into complete meals; (2) the meals have an extended shelf-life and can be transported and stored without need for refrigeration or freezing; (3) preparation of the meal by the consumer is an easy task which is accomplished in ten minutes or less. The meal system was tested in 1975 and 1976 by different groups of elderly individuals. NASA and the LBJ School of Public Affairs sponsored a national conference to report on the demonstration of the meal system for the elderly and to explore potential uses of the system for social services, institutional feeding programs, disaster relief, and international aid. The proceedings of the conference and how different groups assessed the potential of the meal system are reported.

To investigate meal pattern longitudinally and explore whether meal skipping was associated with overweight among Norwegian children and adolescents. Longitudinal study. Children's meal frequencies were reported by their parents using a retrospective FFQ. Weight and height were measured by public health nurses. Descriptive data comparing 4th and 7th grade were analysed by paired-sample t tests for continuous variables and χ 2 tests for categorical variables. Odds ratio estimates, including confidence intervals, with BMI category (normal/overweight) as the dependent variable, were determined through logistic regression analyses. Primary schools, Telemark County, Norway. A cohort of 428 Norwegian boys and girls; 4th graders in 2007, 7th graders in 2010. The number of children eating four main meals per day (regular meal frequency) decreased from 4th grade (47 %) to 7th grade (38 %; P = 0·001). Those who ate regular meals in 4th grade but not in 7th grade had higher odds (OR = 3·1; 95 % CI 1·1, 9·0) of being overweight in 7th grade after adjusting for gender, maternal education and physical activity, but the odds ratio was not statistically significant after adjusting for overweight in 4th grade (OR = 2·8; 95 % CI 0·7, 11·6). The present study showed significant increases in overall meal skipping among children between 4th and 7th grade. The results indicate an association between overweight and meal skipping, but additional prospective and longitudinal analyses and intervention trials are warranted to confirm this relationship.

The experiment consisting of 7 days of digestibility and 90 days of feeding trial was conducted at Wogda (Ethiopia) to determine the effect of supplementation of graded levels of concentrate mix (CM) on feed intake, digestibility, and body weight (BW) change in hay-based feeding of Simada sheep. Twenty-yearling Simada sheep with a mean initial BW of 17.9 +/- 0.81 kg (mean +/- SD) were used in randomized complete block design arranged into five blocks of four animals. The four dietary treatments that consisted of hay alone (T1), hay +150 g dry matter (DM; T2, low), hay +250 g DM (T3, medium), and hay +350 g DM (T4, high) CM were randomly assigned to each sheep within a block. The CM consisted of wheat bran (WB), noug seed (Guizotia abyssinica) meal and safflower (Carthamus tinctorius) seed meal at the ratio of (2:1:1), respectively. Supplementation with T2 and T3 increased (P profitability compared to the control, whereas sheep on the high than the low and medium level of supplementation performed better in these parameters among the supplemented treatments. From the results of this study, T4 is recommended as the best level of supplementation since it resulted in better nutrient utilization, animal performance, and profitability.

Family meals have been associated with improved dietary quality in children and adolescents, and yet very little is known about family meals beyond their frequency. Specific aspects of the breakfast, lunch, and dinner meal environments were described and compared, and the associations with overall diet quality were investigated. Data on food intake and meal environments were obtained in northern Ontario, southern Ontario, and Nova Scotia grades six, seven, and eight classrooms over the 2005 to 2006 school year. Specific aspects of the meal environments described were where the meal was consumed, with whom participants consumed each meal, who prepared the meal, and where the food was originally purchased. Diet quality was assessed using the Canadian version of the Healthy Eating Index. Cluster K-means procedures were used to classify into groups observations about the four meal environment variables. Three, eight, and six clusters of meal environments were identified for breakfast, lunch, and dinner, respectively. Diet quality was negatively associated with consuming/ purchasing meals outside the home, and with skipping breakfast, lunch, and/or dinner. Results have immediate relevance for family-based and/or school programs and policies aimed at educating and feeding children and adolescents.

The objective was to evaluate the inclusion of macaúba seed cake (MSC) meal in diets for growing rabbits by assessing their growth and slaughtering performance, haematological traits, nutritional contribution of caecotrophs, in vitro digestibility, degradability and fermentation parameters. A total of 88 rabbits were distributed to four groups with 22 animals each and fed diets containing 0, 50, 100 and 150 g/kg of MSC, respectively. The in vitro assays were conducted employing cecum inoculum on the same dietary treatments. The inclusion of MSC yielded a quadratic effect on in vitro dry matter digestibility (p protein (p = 0.014), live weight at 51 d (p = 0.024), body weight gain (p = 0.039), average daily feed intake (ADFI) (p = 0.001) and feed conversion ratio (FCR) (p = 0.007) in the first period evaluated (30-50 d); furthermore the ADFI and FCR the second (51-72 d) and whole period (30-72 d) (p < 0.001). MSC addition caused a quadratic effect on white blood cells count (p = 0.026) and a linear decrease of eosinophils (p = 0.045). In conclusion, the inclusion of up to 150 g/kg of MSC improves the in vitro digestibility and fermentation potential of the diets, reflecting on the ADFI and FCR of the animals, although adverse effects are observed on the weight of the commercial carcass and nutritive contribution of the caecotrophs.

Proteolytic and Trypsin Inhibitor Activity in Germinating Jojoba Seeds (Simmondsia chinensis).

Samac, D; Storey, R

1981-12-01

Changes in proteolytic activity (aminopeptidase, carboxypeptidase, endopeptidase) were followed during germination (imbibition through seedling development) in extracts from cotyledons of jojoba seeds (Simmondsia chinensis). After imbibition, the cotyledons contained high levels of sulfhydryl aminopeptidase activity (APA) but low levels of serine carboxypeptidase activity (CPA). CPA increased with germination through the apparent loss of a CPA inhibitor substance in the seed. Curves showing changes in endopeptidase activity (EPA) assayed at pH 4, 5, 6, 7, and 8 during germination were distinctly different. EPA at pH 4, 5, 6, and 7 showed characteristics of sulfhydryl enzymes while activity at pH 8 was probably due to a serine type enzyme. EPA at pH 6 was inhibited early in germination by one or more substances in the seed. Activities at pH 5 and later at pH 6 were the highest of all EPA throughout germination and increases in these activities were associated with a rapid loss of protein from the cotyledons of the developing seedling.Jojoba cotyledonary extracts were found to inhibit the enzymic activity of trypsin, chymotrypsin, and pepsin but not the protease from Aspergillus saotoi. The heat-labile trypsin inhibitor substance(s) was found in commercially processed jojoba seed meal and the albumin fraction of seed proteins. Trypsin inhibitor activity decreased with germination.

Genetic variability and inter-character associations in the mutants of Indian mustard

1980-01-01

To study the genetic variability and the inter-character associations in Indian mustard [Brassica juncea (Linn.)Czern. and Coss. subsp. juncea Linn.], 104 radiation-induced mutants (including 'RLM 198') and 'RL 18' were grown during winter season of 1976-77 at the experimental farm of the Punjab Agricultural University. Analysis of variance revealed significant differences between the mutant genotypes for all the characters under study except for the primary branch number and siliqua number of main shoot, which were non-significant. High estimates of phenotypic coefficients of variation (pcv) and genetic coefficients of variation (gcv) were observed for secondary branch number, seed yield/plant, main shoot length and seed number/siliqua. In general, pcv estimates were higher than gcv estimates. The high estimates of both heritability and genetic advance were recorded in similar order for the plant height, seed number/siliqua, main shoot length and seed yield, in which the genetic progress could be achieved through mass selection. Seed yield was positively correlated with the primary branch number, the secondary branch number and the siliqua number of main shoot and negatively with the plant height. Shorter plant height w;.th more number of primary and secondary branches and more siliquae on main shoot were found to be good selection criteria for isolating high-yielding strains. (auth.)

Does children's energy intake at one meal influence their intake at subsequent meals? Or do we just think it does?

Science.gov (United States)

Hanley, James A; Hutcheon, Jennifer A

2010-05-01

It is widely believed that young children are able to adjust their energy intake across successive meals to compensate for higher or lower intakes at a given meal. This conclusion is based on past observations that although children's intake at individual meals is highly variable, total daily intakes are relatively constant. We investigated how much of this reduction in variability could be explained by the statistical phenomenon of the variability of individual components (each meal) always being relatively larger than the variability of their sum (total daily intake), independent of any physiological compensatory mechanism. We calculated, theoretically and by simulation, how variable a child's daily intake would be if there was no correlation between intakes at individual meals. We simulated groups of children with meal/snack intakes and variability in meal/snack intakes based on previously published values. Most importantly, we assumed that there was no correlation between intakes on successive meals. In both approaches, the coefficient of variation of the daily intakes was roughly 15%, considerably less than the 34% for individual meals. Thus, most of the reduction in variability found in past studies was explained without positing strong 'compensation'. Although children's daily energy intakes are indeed considerably less variable than their individual components, this phenomenon was observed even when intakes at each meal were simulated to be totally independent. We conclude that the commonly held belief that young children have a strong physiological compensatory mechanism to adjust intake at one meal based on intake at prior meals is likely to be based on flawed statistical reasoning.

To analyse the relationship between the frequency of family meals and the body weight of 13-year-olds and its selected determinants. The study was conducted in 2008 as the last stage in a prospective cohort study of 605 children. Questionnaires containing questions about the frequency of family meals, the general regularity of meals, fruit and vegetable consumption, physical activity and the number of hours spent watching television or at the computer were sent to 13-year-olds by mail. School nurses performed anthropometric measurements of the pupils' weight and height. Statistical analyses were performed, i.e. Pearson's correlations, the two-step cluster analysis and the logistic regression analysis. Most of the young people (80-90%) eat each of the main meals in the company of their parents at least once a week, 21% have breakfast with their parents every day, 41% - dinner, and 45% - supper. The frequency of family meals correlated negatively with the girls' BMI and the number of hours they spent watching television or at the computer, while positively with physical activity, regular meals and vegetable consumption in adolescents of both genders. The lowest mean values of BMI were found in a group of adolescents often eating family meals, the highest - in the group of young people who rarely ate family meals (over 20% of young people in this group were overweight), but the differences were statistically significant only for girls (p=0.025). The probability of less than 2 hours of sedentary behaviour daily, physical activity of at least 60 minutes per day and everyday vegetable and fruit consumption is twice as high in adolescents often consuming meals with their parents, and with the daily consumption of all the meals in this way - more than fourfold higher than in other groups. Family meals treated as a predictor of a healthy lifestyle can indirectly protect adolescents from overweight and obesity. Promoting family meals should be an important method of

Background Recent nutrition recommendations advocate a reduction in protein from animal sources (pork, beef) because of environmental concerns. Instead, protein from vegetable sources (beans, peas) should be increased. However, little is known about the effect of these vegetable protein sources on appetite regulation. Objective To examine whether meals based on vegetable protein sources (beans/peas) are comparable to meals based on animal protein sources (veal/pork) regarding meal-induced appetite sensations. Design In total, 43 healthy, normal-weight, young men completed this randomized, double-blind, placebo-controlled, three-way, cross-over meal test. The meals (all 3.5 MJ, 28 energy-% (E%) fat) were either high protein based on veal and pork meat, HP-Meat (19 E% protein, 53 E% carbohydrate, 6 g fiber/100 g); high protein based on legumes (beans and peas), HP-Legume (19 E% protein, 53 E% carbohydrate, 25 g fiber/100 g); or low-protein based on legumes, LP-Legume (9 E% protein, 62 E% carbohydrate, 10 g fiber/100 g). Subjective appetite sensations were recorded at baseline and every half hour using visual analog scales until the ad libitum meal 3 h after the test meal. Repeated measurements analyses and summary analyses were performed using ANCOVA (SAS). Results HP-Legume induced lower composite appetite score, hunger, prospective food consumption, and higher fullness compared to HP-Meat and LP-Legume (ppeas) influenced appetite sensations favorably compared to animal-based meals (pork/veal) with similar energy and protein content, but lower fiber content. Interestingly, a vegetable-based meal with low protein content was as satiating and palatable as an animal-based meal with high protein content. PMID:27765144

StarLink is a genetically modified corn that produces an insecticidal protein, Cry9C. Studies were conducted to determine the variability and Cry9C distribution among sample test results when Cry9C protein was estimated in a bulk lot of corn flour and meal. Emphasis was placed on measuring sampling and analytical variances associated with each step of the test procedure used to measure Cry9C in corn flour and meal. Two commercially available enzyme-linked immunosorbent assay kits were used: one for the determination of Cry9C protein concentration and the other for % StarLink seed. The sampling and analytical variances associated with each step of the Cry9C test procedures were determined for flour and meal. Variances were found to be functions of Cry9C concentration, and regression equations were developed to describe the relationships. Because of the larger particle size, sampling variability associated with cornmeal was about double that for corn flour. For cornmeal, the sampling variance accounted for 92.6% of the total testing variability. The observed sampling and analytical distributions were compared with the Normal distribution. In almost all comparisons, the null hypothesis that the Cry9C protein values were sampled from a Normal distribution could not be rejected at 95% confidence limits. The Normal distribution and the variance estimates were used to evaluate the performance of several Cry9C protein sampling plans for corn flour and meal. Operating characteristic curves were developed and used to demonstrate the effect of increasing sample size on reducing false positives (seller's risk) and false negatives (buyer's risk).

Research has shown the positive associations of family meals and diet quality. However, little is known about how other meals/snacks may be associated with family meals. The purpose was to determine the associations among the frequency and calorie consumption of meals/snacks and family dinners. Cross-sectional. Data were collected using Web-based Eating Behaviour Questionnaire (WEB-Q), including a 24-h diet recall for breakfast, morning snack, lunch, afternoon snack, dinner, and evening snack. Measured height and weight were used to determine body weight status (BMI). Participants included 1068 grade 7 students (52% males) from 26 schools in Windsor Essex County, Ontario, Canada. Meal, snack, and total daily caloric intake; meal and snack frequency; with whom dinner was consumed, and weekly family dinner frequency. Exploratory one-way ANOVAs and chi-square tests; nominal and ordinal logistic regression. Ninety-three percent of participants consumed dinner with family members on the night prior to the survey and 77% reported usually consuming dinner/supper with at least one parent on six to seven nights/week. Those who had dinner with family members consumed 4.88 (SD 1.1) meals/snacks per day compared with 4.40 (SD 1.3) and 4.40 (SD 1.3) times/day for consuming dinner alone or with friends, respectively (p=0.006). On the day prior to the survey, participants were less likely to consume a family meal if they consumed a lower number of meals and snacks per day (OR=0.69 (95% CI: 0.55, 0.87), psnacks per day (OR=0.84 (95% CI: 0.74, 0.96), p=0.009). While specific meals and snacks were not associated with family dinner, overall eating frequency was positively associated with family meals. Copyright © 2014 Elsevier Ltd. All rights reserved.

Full Text Available The real time quantitative reverse transcription PCR (qRT-PCR is becoming increasingly important to gain insight into function of genes. Given the increased sensitivity, ease and reproducibility of qRT-PCR, the requirement of suitable reference genes for normalization has become important and stringent. It is now known that the expression of internal control genes in living organism vary considerably during developmental stages and under different experimental conditions. For economically important Brassica crops, only a couple of reference genes are reported till date. In this study, expression stability of 12 candidate reference genes including ACT2, ELFA, GAPDH, TUA, UBQ9 (traditional housekeeping genes, ACP, CAC, SNF, TIPS-41, TMD, TSB and ZNF (new candidate reference genes, in a diverse set of 49 tissue samples representing different developmental stages, stress and hormone treated conditions and cultivars of Brassica juncea has been validated. For the normalization of vegetative stages the ELFA, ACT2, CAC and TIPS-41 combination would be appropriate whereas TIPS-41 along with CAC would be suitable for normalization of reproductive stages. A combination of GAPDH, TUA, TIPS-41 and CAC were identified as the most suitable reference genes for total developmental stages. In various stress and hormone treated samples, UBQ9 and TIPS-41 had the most stable expression. Across five cultivars of B. juncea, the expression of CAC and TIPS-41 did not vary significantly and were identified as the most stably expressed reference genes. This study provides comprehensive information that the new reference genes selected herein performed better than the traditional housekeeping genes. The selection of most suitable reference genes depends on the experimental conditions, and is tissue and cultivar-specific. Further, to attain accuracy in the results more than one reference genes are necessary for normalization.

Eating in the absence of hunger (EAH) is typically assessed by measuring youths' intake of palatable snack foods after a standard meal designed to reduce hunger. Because energy intake required to reach satiety varies among individuals, a standard meal may not ensure the absence of hunger among participants of all weight strata. The objective of this study was to compare adolescents' EAH observed after access to a very large food array with EAH observed after a standardized meal. Seventy-eight adolescents participated in a randomized crossover study during which EAH was measured as intake of palatable snacks after ad libitum access to a very large array of lunch-type foods (>10,000 kcal) and after a lunch meal standardized to provide 50% of the daily estimated energy requirements. The adolescents consumed more energy and reported less hunger after the large-array meal than after the standardized meal (P values kcal less EAH after the large-array meal than after the standardized meal (295 ± 18 compared with 365 ± 20 kcal; P < 0.001), but EAH intakes after the large-array meal and after the standardized meal were positively correlated (P values < 0.001). The body mass index z score and overweight were positively associated with EAH in both paradigms after age, sex, race, pubertal stage, and meal intake were controlled for (P values ≤ 0.05). EAH is observable and positively related to body weight regardless of whether youth eat in the absence of hunger from a very large-array meal or from a standardized meal. This trial was registered at clinicaltrials.gov as NCT00631644.

Thiourea, a ROS scavenger, regulates source-to-sink relationship to enhance crop yield and oil content in Brassica juncea (L..

Directory of Open Access Journals (Sweden)

Manish Pandey

Full Text Available In the present agricultural scenario, the major thrust is to increase crop productivity so as to ensure sustainability. In an earlier study, foliar application of thiourea (TU; a non physiological thiol based ROS scavenger has been demonstrated to enhance the stress tolerance and yield of different crops under field condition. Towards this endeavor, present work deals with the effect of TU on photosynthetic efficiency and source-to-sink relationship of Indian mustard (Brassica juncea for understanding its mode of action. The application of TU increased the efficiency of both PSI and PSII photosystems and vegetative growth of plant. The comparative analysis of sucrose to starch ratio and expression level of sugar transporters confirmed the higher source and sink strength in response to TU treatment. The biochemical evidence in support of this was derived from higher activities of sucrose phosphate synthase and fructose-1,6-bis-phosphatase at source; and sucrose synthase and different classes of invertases at both source and sink. This indicated an overall increase in photoassimilate level at sink. An additional contribution through pod photosynthesis was confirmed through the analysis of phosphoenol pyruvate carboxylase enzyme activity and level of organic acids. The increased photoassimilate level was also co-ordinated with acetyl coA carboxylase mediated oil biosynthesis. All these changes were ultimately reflected in the form of 10 and 20% increase in total yield and oil content, respectively under TU treatment as compared to control. Additionally, no change was observed in oil composition of seeds derived from TU treated plants. The study thus signifies the co-ordinated regulation of key steps of photosynthesis and source-to-sink relationship through the external application of TU resulting in increased crop yield and oil content.

Meal pattern analysis can be complex because of the large variability in meal consumption. The use of aggregated, generic meal data may address some of these issues. The objective was to develop a meal coding system and use it to explore meal patterns. Dietary data were used from the National Adult Nutrition Survey (2008-2010), which collected 4-d food diary information from 1500 healthy adults. Self-recorded meal types were listed for each food item. Common food group combinations were identified to generate a number of generic meals for each meal type: breakfast, light meals, main meals, snacks, and beverages. Mean nutritional compositions of the generic meals were determined and substituted into the data set to produce a generic meal data set. Statistical comparisons were performed against the original National Adult Nutrition Survey data. Principal component analysis was carried out by using these generic meals to identify meal patterns. A total of 21,948 individual meals were reduced to 63 generic meals. Good agreement was seen for nutritional comparisons (original compared with generic data sets mean ± SD), such as fat (75.7 ± 29.4 and 71.7 ± 12.9 g, respectively, P = 0.243) and protein (83.3 ± 26.9 and 80.1 ± 13.4 g, respectively, P = 0.525). Similarly, Bland-Altman plots demonstrated good agreement (<5% outside limits of agreement) for many nutrients, including protein, saturated fat, and polyunsaturated fat. Twelve meal types were identified from the principal component analysis ranging in meal-type inclusion/exclusion, varying in energy-dense meals, and differing in the constituents of the meals. A novel meal coding system was developed; dietary intake data were recoded by using generic meal consumption data. Analysis revealed that the generic meal coding system may be appropriate when examining nutrient intakes in the population. Furthermore, such a coding system was shown to be suitable for use in determining meal-based dietary patterns. © 2015

Sustainable agriculture is defined as the successful management of resources for agriculture to satisfy changing human needs while maintaining or enhancing the quality of the environment and conserving natural resources. A sustained increase of agricultural production becomes a great possibility for international community. In this process a green manure crops application for example crotalaria get a new chance for improvement process on soil fertility and soil conservation. Field experiment was carried out on a calcareous chernozem soil (Experiment station Nagyhörcsök of RISSAC-HAS) in partly of experiment series (3 years) at Hungary in 1998. The soil with about 20% clay, 3% humus, 5% CaCO3 in its ploughed layer. To ensure a sufficient macro and micronutrient supply in the whole experiment, 100 kg N, 100 kg P2O5 and 100 kg K2O were given hectare. The Crotalaria juncea L. and Crotalaria spectabilis ROTH were applied with 2 replications. Each plot has an area of 45 m2 with 230-230 individual plants. In vegetation grown period were measured green and dry matter yield. The soil and plant samples were analysed for the macro and microelements contents. The main results achieved in 1998 are summarized as follows: 1. The green matter yield at before flowering reached 63.8 t ha-1 in case of Crotalaria juncea L. 2. Total dry matter yield at harvest (without roots) fluctuated between 9.6 and 17.0 t ha-1, depending on the crotalaria species. 3. The average of element concentration (including stems, leaves of Crotalaria juncea L. and Crotalaria spectabilis ROTH) before flowering reached to 3.2 % N, 2.3 % Ca, 1.3 % K, 0.39 % Mg, 0.22 % P and 0.24 % S. The content of Al and Fe total 14 - 25, while that of Sr, Mn, Na, B and Ba 2 - 6 ppm in dry matter. The Zn, Cu, Mo, Cr, Se, Ni, As, Pb, Cd and Co concentration did not reach here the value of 1 ppm. 4. The average of biological activated element uptake (including stems, leaves of Crotalaria juncea L. and Crotalaria spectabilis

Mercury, a potent neurotoxin, is released to the environment in significant amounts by both natural processes and anthropogenic activities. No natural hyperaccumulator plant has been reported for mercury phytoremediation. Few studies have been conducted on the physiological responses of Indian mustard, a higher biomass plant with faster growth rates, to mercury pollution. This study investigated the phytotoxicity of mercury to Indian mustard (Brassica juncea L.) and mercury-induced oxidative stress in order to examine the potential application of Indian mustard to mercury phytoremediation. Two common cultivars (Florida Broadleaf and Longstanding) of Indian mustard were grown hydroponically in a mercury-spiked solution. Plant uptake, antioxidative enzymes, peroxides, and lipid peroxidation under mercury stress were investigated. Antioxidant enzymes (catalase, CAT; peroxidase, POD; and superoxide dismutase, SOD) were the most sensitive indices of mercury-induced oxidative response of Indian mustard plants. Indian mustard effectively generated an enzymatic antioxidant defense system (especially CAT) to scavenge H(2)O(2), resulting in lower H(2)O(2) in shoots with higher mercury concentrations. These two cultivars of Indian mustard demonstrated an efficient metabolic defense and adaptation system to mercury-induced oxidative stress. A majority of Hg was accumulated in the roots and low translocations of Hg from roots to shoots were found in two cultivars of Indian mustard. Thus Indian mustard might be a potential candidate plant for phytofiltration/phytostabilization of mercury contaminated waters and wastewater.

Cytoplasmic male sterility (CMS) is not only important for exploiting heterosis in crop plants, but also as a model for investigating nuclear-cytoplasmic interaction. CMS may be caused by mutations, rearrangement or recombination in the mitochondrial genome. Understanding the mitochondrial genome is often the first and key step in unraveling the molecular and genetic basis of CMS in plants. Comparative analysis of the mitochondrial genome of the hau CMS line and its maintainer line in B. juneca (Brassica juncea) may help show the origin of the CMS-associated gene orf288. Through next-generation sequencing, the B. juncea hau CMS mitochondrial genome was assembled into a single, circular-mapping molecule that is 247,903 bp in size and 45.08% in GC content. In addition to the CMS associated gene orf288, the genome contains 35 protein-encoding genes, 3 rRNAs, 25 tRNA genes and 29 ORFs of unknown function. The mitochondrial genome sizes of the maintainer line and another normal type line "J163-4" are both 219,863 bp and with GC content at 45.23%. The maintainer line has 36 genes with protein products, 3 rRNAs, 22 tRNA genes and 31 unidentified ORFs. Comparative analysis the mitochondrial genomes of the hau CMS line and its maintainer line allowed us to develop specific markers to separate the two lines at the seedling stage. We also confirmed that different mitotypes coexist substoichiometrically in hau CMS lines and its maintainer lines in B. juncea. The number of repeats larger than 100 bp in the hau CMS line (16 repeats) are nearly twice of those found in the maintainer line (9 repeats). Phylogenetic analysis of the CMS-associated gene orf288 and four other homologous sequences in Brassicaceae show that orf288 was clearly different from orf263 in Brassica tournefortii despite of strong similarity. The hau CMS mitochondrial genome was highly rearranged when compared with its iso-nuclear maintainer line mitochondrial genome. This study may be useful for studying the

To describe shared meal patterns and examine associations with dietary intake among young adults. Population-based, longitudinal cohort study (Project EAT: Eating and Activity in Teens and Young Adults). Participants completed surveys and FFQ in high-school classrooms in Minneapolis/St. Paul, MN, USA in 1998-1999 (mean age = 15·0 years, 'adolescence') and follow-up measures online or by mail in 2008-2009 (mean age = 25·3 years, 'young adulthood'). There were 2052 participants who responded to the 10-year follow-up survey and reported on frequency of having shared meals. Among young adults, the frequency of shared meals during the past week was as follows: never (9·9 %), one or two times (24·7 %), three to six times (39·1 %) and seven or more times (26·3 %). Having more frequent family meals during adolescence predicted a higher frequency of shared meals in young adulthood above and beyond other relevant sociodemographic factors such as household composition and parental status. Compared with young adults who never had family meals during adolescence, those young adults who reported seven or more family meals per week during adolescence had an average of one additional shared meal per week. Having more frequent shared meals in young adulthood was associated with greater intake of fruit among males and females, and with higher intakes of vegetables, milk products and some key nutrients among females. Nutrition professionals should encourage families of adolescents to share meals often and establish the tradition of eating together, and work with young adults to ensure that healthy food and beverage choices are offered at mealtimes.

Guangzhou’s Baozai Meal a Popular Fast Food

Institute of Scientific and Technical Information of China (English)

1995-01-01

IN Guangzhou, where restaurants are plentiful and food from many places is served, the baozai meal, a kind of traditional Chinese fast food, has retained its place in the hearts of Guangzhou’s caterers. The history of the baozai meal starts at least from the beginning of this century. By the end of the Qing Dynasty, Guangzhou was the largest trading port in south China with a developed, commodities-based economy. There were many dockworkers and porters living in the city at the time. They worked very hard and were often too busy to eat their meals at home. As a result, different kinds of meals were invented to meet their needs, such as the botou meal (bo is kind of earthen bowl), the dietou meal (die is small plate) and the baozai meal

Proteolytic and Trypsin Inhibitor Activity in Germinating Jojoba Seeds (Simmondsia chinensis) 1

1981-01-01

Changes in proteolytic activity (aminopeptidase, carboxypeptidase, endopeptidase) were followed during germination (imbibition through seedling development) in extracts from cotyledons of jojoba seeds (Simmondsia chinensis). After imbibition, the cotyledons contained high levels of sulfhydryl aminopeptidase activity (APA) but low levels of serine carboxypeptidase activity (CPA). CPA increased with germination through the apparent loss of a CPA inhibitor substance in the seed. Curves showing changes in endopeptidase activity (EPA) assayed at pH 4, 5, 6, 7, and 8 during germination were distinctly different. EPA at pH 4, 5, 6, and 7 showed characteristics of sulfhydryl enzymes while activity at pH 8 was probably due to a serine type enzyme. EPA at pH 6 was inhibited early in germination by one or more substances in the seed. Activities at pH 5 and later at pH 6 were the highest of all EPA throughout germination and increases in these activities were associated with a rapid loss of protein from the cotyledons of the developing seedling. Jojoba cotyledonary extracts were found to inhibit the enzymic activity of trypsin, chymotrypsin, and pepsin but not the protease from Aspergillus saotoi. The heat-labile trypsin inhibitor substance(s) was found in commercially processed jojoba seed meal and the albumin fraction of seed proteins. Trypsin inhibitor activity decreased with germination.

Full Text Available Three experiments were carried out to determine the nutritional values and evaluate the performance of piglets fed on canola meal. In experiment I, a digestibility assay was conducted using fourteen barrow pigs, with an initial body weight of 20.62±3.30 kg. The evaluated feedstuff was canola meal, with a level of 250 g/kg in the basal diet (corn + soybean meal-based. The experimental unit consisted of one pig, with a total of seven experimental units per diet. The values as (fed basis of digestible (DE and metabolizable (ME energy of canola meal were 2,995 kcal/kg and 2,796 kcal/kg, respectively. In experiment II, ileal digestibility assays were carried out to determine the apparent and true ileal digestibility coefficient and digestible amino acids. Three crossbred pigs were used, with a BW of 38.6±1.98 kg. The treatments consisted of two diets, with a single source of protein (canola meal and one protein-free diet (OFD. The values of digestible amino acids in canola meal were as follows: lysine: 11.8 g/kg; methionine+cystine: 9.1 g/kg; threonine: 7.9 g/kg; tryptophan: 2.4 g/kg; leucine: 15.7 g/kg; and isoleucine: 8.7 g/kg. In experiment III, 60 piglets (BW= 15.08±0.72 kg to 30.26±2.78 kg were allotted in a completely randomized design. The treatments consisted of four diets with increasing levels of canola meal (50, 100, 150 and 200 g/kg, six replicates and experimental unit consisted of two pigs. Additionally, a control diet was formulated containing 0.0 g/kg CM. Regression analysis indicates that there was no effect (P?0.05 of the level of canola meal inclusion on pigs performance. The performance results suggest that it is feasible to use up to 200 g/kg of canola meal in starting pigs diet, without impairing performance and the feeding cost.

American children consume up to 27% of calories from high-fat and high-sugar snacks. Both sugar and fat consumption have been implicated as a cause of hepatic steatosis and obesity but the effect of meal pattern is largely understudied. We hypothesized that a high meal frequency, compared to consuming large meals, is detrimental in the accumulation of intrahepatic and abdominal fat. To test this hypothesis, we randomized 36 lean, healthy men to a 40% hypercaloric diet for 6 weeks or a eucaloric control diet and measured intrahepatic triglyceride content (IHTG) using proton magnetic resonance spectroscopy ((1) H-MRS), abdominal fat using magnetic resonance imaging (MRI), and insulin sensitivity using a hyperinsulinemic euglycemic clamp with a glucose isotope tracer before and after the diet intervention. The caloric surplus consisted of fat and sugar (high-fat-high-sugar; HFHS) or sugar only (high-sugar; HS) and was consumed together with, or between, the three main meals, thereby increasing meal size or meal frequency. All hypercaloric diets similarly increased body mass index (BMI). Increasing meal frequency significantly increased IHTG (HFHS mean relative increase of 45%; P = 0.016 and HS mean relative increase of 110%; P = 0.047), whereas increasing meal size did not (2-way analysis of variance [ANOVA] size versus frequency P = 0.03). Abdominal fat increased in the HFHS-frequency group (+63.3 ± 42.8 mL; P = 0.004) and tended to increase in the HS-frequency group (+46.5 ± 50.7 mL; P = 0.08). Hepatic insulin sensitivity tended to decrease in the HFHS-frequency group while peripheral insulin sensitivity was not affected. A hypercaloric diet with high meal frequency increased IHTG and abdominal fat independent of caloric content and body weight gain, whereas increasing meal size did not. This study suggests that snacking, a common feature in the Western diet, independently contributes to hepatic steatosis and obesity. ( www

The effect of bread consumption on overall food intake is poorly understood. The aim of this study was to measure postprandial food intake after a set breakfast containing three different breads. Ten males and 10 females aged 20.1-44.8 years, BMI 18.4-24.8 kg/m(2), consumed two slices of White Bread, Bürgen Wholemeal and Seeds Bread or Lupin Bread (all 1300 kJ) with 10 g margarine and 30 g strawberry jam.

Full Text Available The effect of replacing of 0; 0.33; 0.67 and 1.0 (kg/kg of soybean meal (SBM by undecorticated castor seed meal treated with calcium oxide (CMT - 60 g/kg was evaluated on performance and efficiency of nutrient utilization in dairy cows. Sixteen Holstein and crossbred cows were distributed in four 4 × 4 latin squares. Animals received concentrated feed at a ratio of 1 kg for 3 kg of milk produced, in the natural matter. The diets had the same amount of nitrogen (150.4 g crude protein/kg DM, containing 325.6 g of concentrated feed/kg DM. There was no effect on the serum concentration of transaminase and the animals showed no clinical symptoms of intoxication by ricin. The intake of DM, crude protein (CP and non-fibrous carbohydrates (NFC reduced from 0.67 replacement of SBM by CMT. The intake of neutral detergent fibers corrected for ash and protein (NDFap increased from 0.33 replacement of SBM with CMT. Although the digestibility of dietary components decreased from 0.33 replacement, the intake of digestible components only reduced from 0.67 replacement. Because of the reduction of digestible energy, the synthesis of microbial CP and the utilization efficiency of rumen-degradable protein for the synthesis of microbial CP reduced with full replacement of SBM by CMT. Milk yield, milk composition, daily variation of body weight and the efficiency of utilization of the nutrients for the synthesis of N in milk reduced from 0.67 replacement of SBM by CMT. Castor seed meal treated with calcium oxide can replace up to 0.33 of SBM (50 g/kg DM diet DM in the diet of dairy cows with an average milk production of 20 kg/day.

Ground annatto seeds (Bixa orellana L. in sorghum-based commercial layer diets and their effects on performance, egg quality, and yolk pigmentation

Directory of Open Access Journals (Sweden)

EA Garcia

2010-12-01

Full Text Available Consumer demands for healthy foods have stimulated the research on the use of natural products in animal nutrition. Annatto can be used a pigmentation source to improve yolk color of commercial eggs. This study aimed at evaluating the effects of the inclusion of ground annatto seeds on the performance and egg quality of layers fed sorghum-based diets. A total of 336 40-w-old hens were distributed according to randomized blocks into seven treatments with six replicates of eight birds each. The following treatments were applied: T1- egg production feed based on corn and soybean meal; T2- egg production feed based on sorghum and soybean meal; T3, T4, T5, T6, and T7- egg production feed based on sorghum supplemented with 0.5, 1.0, 1.5, 2.0, and 2.5% ground annatto seeds, respectively. As to performance parameters, only egg production was influenced, with hens fed the corn-based diet producing more eggs than those fed the sorghum-based diet with inclusion of 1.5 and 2.5% de annatto. The only egg quality parameter affected by treatments was the color of yolk, which pigmentation increased with increasing levels of ground annatto seeds. It is concluded that ground annatto seeds can be supplemented in sorghum-based production feeds for layers, and that the inclusion level of 0.89% is sufficient to promote the same yolk pigmentation as that obtained with corn-based diets.

Full Text Available The objective of this study was to evaluate the effect of substituting soybean meal for cottonseed meal in multiple supplements on the nutritional characteristics and performance of beef heifers in their postweaning phase on Brachiaria decumbens pastures during the dry season. Twenty-four Nellore beef heifers (average initial age and weight of 8 mo and 210±6 kg, respectively were used. The design was completely randomized, with four treatments and six replicates. Supplements contained approximately 30% crude protein (CP and a progressive substitution of soybean meal for cottonseed meal (0, 50 and 100%. The control animals received only a mineral mixture ad libitum, and those on the other treatments received supplementation at 1.0 kg/animal/day. No differences were found in ADG between supplemented and control animals (P>0.10. Supplementation increased crude protein (CP intake only (P<0.10. The level of substitution of soybean meal for cottonseed meal did not affect (P>0.10 the intake of supplemented animals. Supplementation elevated the apparent digestibility coefficients (P<0.10 of OM, CP, NFC and TDN, but not EE or NDFap (P>0.10. A positive linear effect (P<0.10 of the level of substitution of soybean meal for cottonseed cake was observed on the digestibility of OM, NFC and TDN. Supplementation and the level of substitution had an effect (P<0.10 on the serum urea nitrogen and urine urea nitrogen contents. Supplementation or substitution level had no effect on the flow of microbial nitrogen to the intestine (MICN or efficiency of microbial protein synthesis (EMPS (P>0.10. Substitution caused a decreasing linear effect (P<0.10 on microbial nitrogen/nitrogen intake ratio (MICNR. In conclusion, substitution of soybean meal for cottonseed meal in multiple supplements during the dry season does not impair the productive performance of beef heifers.

Full Text Available Commom protein sources for poultry, fish meal and soybean meal, were ground to obtain reduced particle size. The particle was then dissolved in distilled water (1 : 4 w/v, and added with 2 mL virgin coconut oil for every 500 mL solution prior to ultrasound transducer (ultrasonic bath treatment to obtain protein microparticle. Reducing particle size is one possible way to increase protein utilization.180 birds were used for forced feeding and 10 other birds were plotted for endogenous correction, when they were one month and a half old. Microparticle protein of both ingredients were tested separately in either mash or pelleted forms and compared to intact protein. Completely randomized design with 3 treatments (intact, mash, and pellet and 6 replications (10 bidrs each was arranged for the respective ingredient. Protein and essential amino acid digestibilities, and calcium retention were the parameters measured. Analysis of variance continued to Duncan test were applied to statistically evaluate the data. Pelleted microparticle protein of fish meal and soybean meal, respectively, resulted in significantly (P<0.05 highest protein and amino acids digestibilities, and Ca retention although lower disgestibility of fewer amino acids was found in mash form. In conclusion, pelleted form of microparticle protein of either fish meal or soybean meal improve protein and mostly amino acids digestibilities, and calcium retention in broiler.

Full Text Available Plants of Brassica juncea L. var. RLC-1 were exposed for 30 days to different concentrations (0, 0.2, 0.4, and 0.6 mM of cadmium (Cd to analyze the Cd uptake, H2O2 content, hormonal profiling, level of photosynthetic pigments (chlorophyll, carotenoid, and flavonoid, gaseous exchange parameters (photosynthetic rate, vapour pressure deficit, intercellular CO2 concentration, and intrinsic mesophyll rate, antioxidative enzymes (superoxide dismutase, polyphenol oxidase, glutathione-S transferase, and glutathione peroxidase, antioxidant assays (DPPH, ABTS, and total phenolic content, and polyphenols. Results of the present study revealed the increased H2O2 content and Cd uptake with increasing metal doses. UPLC analysis of plants showed the presence of various polyphenols. Gaseous exchange measurements were done by infrared gas analyzer (IRGA, which was negatively affected by metal treatment. In addition, LC/MS study showed the variation in the expression of plant hormones. Level of photosynthetic pigments and activities of antioxidative enzymes were altered significantly in response to metal treatment. In conclusion, the antioxidative defence system of plants got activated due to heavy metal stress, which protects the plants by scavenging free radicals.

Full Text Available Two experiments were conducted to evaluate the effect of replacing soybean meal with xylose-treated soybean meal (soypass meal; SPM on performance of nursing Awassi ewes and fattening lambs. In Experiment 1, lasting for eight weeks, 39 Awassi ewes and their lambs were randomly assigned to three diets. Diets were formulated by replacing soybean meal from the basal diet (CON-SBM; n=13 with 50% (50% SPM; n=13 and 100% (100% SPM; n=13 SPM. Initial and final weights of the ewes were not different (P>0.55 among diets. Total gain and average daily gain (ADG of lambs were similar (P=0.44 among diets. Ewes fed the CON-SBM diet tended (P0.38 in milk component percentages among diets were observed. In Experiment 2, lasting for 63 days, twenty weaned lambs were used to determine the effects of replacing soybean meal with SPM on growth performance. Diets were either soybean meal (SBM; n=10 or SPM (SPM; n=10. Nutrient intake and digestibility were not different between diets. However, rumen undegradable protein intake was greater (P0.05 between the diets. Results suggest that replacement of soybean meal with soypass meal is not likely to produce any production benefits in nursing Awassi ewes and fattening lambs except for the slight improvement of milk yield.

Erkan, Deniz; Kayali, Hulya Ayar

2016-09-01

Ramoplanin A2 is the last resort antibiotic for treatment of many high morbidity- and mortality-rated hospital infections, and it is expected to be marketed in the forthcoming years. Therefore, high-yield production of ramoplanin A2 gains importance. In this study, meat-bone meal, poultry meal, and fish meal were used instead of soybean meal for ramoplanin A2 production by Actinoplanes sp. ATCC 33076. All animal origin nitrogen sources stimulated specific productivity. Ramoplanin A2 levels were determined as 406.805 mg L(-1) in fish meal medium and 374.218 mg L(-1) in poultry meal medium. These levels were 4.25- and 4.09-fold of basal medium, respectively. However, the total yield of poultry meal was higher than that of fish meal, which is also low-priced. In addition, the variations in pH levels, protein levels, reducing sugar levels, extracellular protease, amylase and lipase activities, and intracellular free amino acid levels were monitored during the incubation period. The correlations between ramoplanin production and these variables with respect to the incubation period were determined. The intracellular levels of L-Phe, D-Orn, and L-Leu were found critical for ramoplanin A2 production. The strategy of using animal origin nitrogen sources can be applied for large-scale ramoplanin A2 production.

Full Text Available Background: Recent nutrition recommendations advocate a reduction in protein from animal sources (pork, beef because of environmental concerns. Instead, protein from vegetable sources (beans, peas should be increased. However, little is known about the effect of these vegetable protein sources on appetite regulation. Objective: To examine whether meals based on vegetable protein sources (beans/peas are comparable to meals based on animal protein sources (veal/pork regarding meal-induced appetite sensations. Design: In total, 43 healthy, normal-weight, young men completed this randomized, double-blind, placebo-controlled, three-way, cross-over meal test. The meals (all 3.5 MJ, 28 energy-% (E% fat were either high protein based on veal and pork meat, HP-Meat (19 E% protein, 53 E% carbohydrate, 6 g fiber/100 g; high protein based on legumes (beans and peas, HP-Legume (19 E% protein, 53 E% carbohydrate, 25 g fiber/100 g; or low-protein based on legumes, LP-Legume (9 E% protein, 62 E% carbohydrate, 10 g fiber/100 g. Subjective appetite sensations were recorded at baseline and every half hour using visual analog scales until the ad libitum meal 3 h after the test meal. Repeated measurements analyses and summary analyses were performed using ANCOVA (SAS. Results: HP-Legume induced lower composite appetite score, hunger, prospective food consumption, and higher fullness compared to HP-Meat and LP-Legume (p<0.05. Furthermore, satiety was higher after HP-Legume than HP-Meat (p<0.05. When adjusting for palatability, HP-Legume still resulted in lower composite appetite scores, hunger, prospective consumption, and higher fullness compared to HP-Meat (p<0.05. Furthermore, HP-Legume induced higher fullness than LP-Legume (p<0.05. A 12% and 13% lower energy intake, respectively, was seen after HP-Legume compared to HP-Meat or LP-Legume (p<0.01. Conclusion: Vegetable-based meals (beans/peas influenced appetite sensations favorably compared to animal-based meals

Ciccantelli, B; Pribic, T; Malagelada, C; Accarino, A; Azpiroz, F

2017-05-01

Ingestion of a meal induces cognitive and hedonic sensations and our aim was to determine the relation between both dimensions. In three groups of healthy non-obese men (n=10 per group) three types of meals with equivalent levels of palatability were tested: a liquid meal, a solid-liquid low-calorie meal, and a solid-liquid high-calorie meal. The cognitive and hedonic responses were measured on 10-cm scales before and during the 30-minute postprandial period. The liquid meal induced a relatively strong cognitive response with satiation (4.7±0.7 score increment), fullness (3.3±0.7 score increment), and inhibition of desire of eating a food of choice; in contrast, its impact on sensation of digestive well-being and satisfaction was not significant (0.7±0.7 score increment). The high-calorie solid-liquid meal, with larger volume load and caloric content, induced much lower satiation (2.4±0.8 score increment; P=.041 vs liquid meal) and fullness sensation (1.3±0.6 score increment; P=.031 vs liquid meal), but a markedly higher level of satisfaction (2.7±0.4 score increment; P=.021 vs liquid meal); the low-calorie mixed meal had less prominent effects with significantly lower satisfaction (1.0±0.4 score increment; P=.039 vs high-calorie meal). The cognitive (satiation, fullness) and hedonic responses (satisfaction) to meals with equivalent levels of palatability, that is, equally likable, are dissociable. The characteristics of meals in terms of satiation and rewarding power could be adapted to specific clinical targets, whether nutritional supplementation or restriction. © 2017 John Wiley & Sons Ltd.

The objectives of this study were to: (1) Use molecular spectroscopy as a novel technique to quantify protein molecular structures in relation to its chemical profiles and bioenergy values in oil-seeds and co-products from bio-oil processing. (2) Determine and compare: (a) protein molecular structure using Fourier transform infrared (FT/IR-ATR) molecular spectroscopy technique; (b) bioactive compounds, anti-nutritional factors, and chemical composition; and (c) bioenergy values in oil seeds (canola seeds), co-products (meal or pellets) from bio-oil processing plants in Canada in comparison with China. (3) Determine the relationship between protein molecular structural features and nutrient profiles in oil-seeds and co-products from bio-oil processing. Our results showed the possibility to characterize protein molecular structure using FT/IR molecular spectroscopy. Processing induced changes between oil seeds and co-products were found in the chemical, bioenergy profiles and protein molecular structure. However, no strong correlation was found between the chemical and nutrient profiles of oil seeds (canola seeds) and their protein molecular structure. On the other hand, co-products were strongly correlated with protein molecular structure in the chemical profile and bioenergy values. Generally, comparisons of oil seeds (canola seeds) and co-products (meal or pellets) in Canada, in China, and between Canada and China indicated the presence of variations among different crusher plants and bio-oil processing products.

A randomised crossover dietary intervention study. Nottingham, UK--Healthy free-living women. A total of nine lean healthy women aged 18-42 y recruited via advertisement. A randomised crossover trial with two phases of 14 days each. In Phase 1, subjects consumed their normal diet on either 6 occasions per day (regular) or by following a variable meal frequency (3-9 meals/day, irregular). In Phase 2, subjects followed the alternative meal pattern to that followed in Phase 1, after a 2-week (wash-out) period. Subjects were asked to come to the laboratory after an overnight fast at the start and end of each phase. Blood samples were taken for measurement of circulating glucose, lipids, insulin and uric acid concentrations before and for 3 h after consumption of a high-carbohydrate test meal. Fasting glucose and insulin values were not affected by meal frequency, but peak insulin and AUC of insulin responses to the test meal were higher after the irregular compared to the regular eating patterns (P meal frequency was associated with higher fasting total (P meal frequency appears to produce a degree of insulin resistance and higher fasting lipid profiles, which may indicate a deleterious effect on these cardiovascular risk factors. : The Ministry of Health and Medical Education, IR Iran.

The present study quantitatively explored the effects of mothers' perceived time pressure, as well as meal-related variables including mothers' convenience orientation and meal preparation confidence, on the healthiness of evening meals served to school-aged children (5-18 years old) over a 7-day period. A sample of 120 employed mothers, who identified themselves as the chief meal-preparers in their households, completed a brief, self-report, meal-related questionnaire. Results revealed that mothers' perceived time pressure did not significantly predict meal healthiness. Mothers' confidence in their ability to prepare a healthy meal was the only unique, significant predictor of a healthy evening meal. Mothers who were more confident in their ability to prepare a healthy meal served healthier evening meals than those who were less confident. In addition, mothers' perceived time pressure and convenience orientation were negatively related to healthy meal preparation confidence. Results suggest that mothers' perceived time pressure and convenience orientation, may indirectly compromise meal healthiness, by decreasing mothers' meal preparation confidence. Practical and theoretical implications of the study's findings are discussed. Copyright © 2010 Elsevier Ltd. All rights reserved.

To evaluate the planning, production, distribution, and nutritional adequacy of meals served at city schools. This descriptive cross-sectional study was conducted between March 2011 and April 2012 and included a representative sample (n = 42 schools) of extended shift city schools from Belo Horizonte, Minas Gerais, Brazil. Five meals from each school were randomly selected and analyzed by direct weighing. Production indicators and nutritional adequacy were evaluated in contrast to the recommendations of the city food security bureau and the Brazilian National Program of School Meals (PNAE). Seventy-nine percent of the analyzed meals did not meet the recommendations of the city food security bureau. The rate of waste (food left on plates) was acceptable at 4,90%, but the rates of cooked and not served food (7,06%) and counter leftovers (5,30%) were high. Both the city planned meals and the meals served in the schools were nutritionally inadequate in terms of the PNAE, particularly for children aged 11-15 years. There was a relationship between consumption by school staff and the amount of food that was cooked (r = 0.353; P planning, production, and distribution of school meals and of food and nutrition education in order to improve the quality of food and to reduce waste in schools.

Meal frequency and timing: impact on metabolic disease risk.

Science.gov (United States)

Varady, Krista A

2016-10-01

The purpose of this article is to provide an overview of the most recent human intervention trials that have examined the impact of meal frequency or meal timing on metabolic disease risk factors. Findings from intervention studies published over the past 12 months indicate that weight loss may be more pronounced with decreased meal frequency (two meals per day) versus increased meal frequency (six meals per day) under hypocaloric conditions. However, under isocaloric conditions, no effect on body weight was noted. Plasma lipid concentrations and glucoregulatory factors (fasting glucose, insulin, and insulin sensitivity) were not affected by alterations in meal frequency. As for meal timing, delaying the lunchtime meal by 3.5 h (from 1.30 p.m. to 4.30 p.m.) has no impact on body weight, but may impair glucose tolerance in young healthy adults. In sum, altering meal frequency has little impact on body weight, plasma lipids, or glucoregulatory factors, whereas eating the majority of calories later in the day may be detrimental for glycemic control. These preliminary findings, however, still require confirmation by longer term, larger scale controlled trials.

The epidemiology of family meals among adults at a population level is poorly characterized and whether living with children impacts this health behaviour is uncertain. We determined the prevalence of family meals among US adults in a mid-western state whose families did and did not include minor children and described how it varied by sociodemographic characteristics. The cross-sectional 2012 Ohio Medicaid Assessment Survey is representative of Ohio adults and included questions on their sociodemographic characteristics and the frequency with which they eat family meals at home. Trained interviewers administered landline and cell phone surveys to adults sampled from Ohio's non-institutionalized population. We analysed data from 5766 adults living with minor children and 8291 adults not living alone or with children. The prevalence of family meals was similar for adults who did and did not live with minor children: 47 % (95 % CI 46, 49 %) of adults living with and 51 % (95 % CI 50, 53 %) of adults living without children reported eating family meals on most (six or seven) days of the week. Family meal frequency varied by race/ethnicity, marital and employment status in both groups. Non-Hispanic African-American adults, those who were not married and those who were employed ate family meals less often. Adults in Ohio frequently shared meals with their family and family meal frequency was not strongly related to living with children. Broadening the scope of future studies to include adults who are not parents could enhance our understanding of the potential health benefits of sharing meals.

Iron absorption from adequate Filipino meals representing the three major island groups of the Philippines (Luzon, Visayas, and Mindanao) was studied using double isotope extrinsic tag method. Mean iron absorption of the one-day meal for Metro Manila was 6.6 +- 1.26%. Central Visayas, 6.3 +- 1.15% and Southern Mindanao, 6.4 +- 1.19%. Comparison between meals (breakfast, lunch, dinner) for each region as well as one-day meal for the three regions showed no significant differences (P>0.01). Correlation tests done between iron absorption and the following iron enhancers: ascorbic acid, amount of fish, meat or poultry; and inhibitors: phytic acid and tannic acid, did not give significant results. The overall average of 6.4 +- 1.20% may be used as the iron absorption level from an adequate Filipino meal. This value can be considered as one of the bases for arriving at recommended dietary allowances for iron among Filipinos instead of the 10% iron absorption assumed in 1976.

Laboratory studies have demonstrated that experimental manipulations of oral processing can have a marked effect on energy intake. Here, we explored whether variations in oral processing across a range of unmodified everyday meals could affect post-meal fullness and meal size. In Study 1, female participants (N = 12) attended the laboratory over 20 lunchtime sessions to consume a 400-kcal portion of a different commercially available pre-packaged meal. Prior to consumption, expected satiation was assessed. During each meal, oral processing was characterised using: (i) video-recordings of the mouth and (ii) real-time measures of plate weight. Hunger and fullness ratings were elicited pre- and post-consumption, and for a further three hours. Foods that were eaten slowly had higher expected satiation and delivered more satiation and satiety. Building on these findings, in Study 2 we selected two meals (identical energy density) from Study 1 that were equally liked but maximised differences in oral processing. On separate days, male and female participants (N = 24) consumed a 400-kcal portion of either the "fast" or "slow" meal followed by an ad libitum meal (either the same food or a dessert). When continuing with the same food, participants consumed less of the slow meal. Further, differences in food intake during the ad libitum meal were not compensated at a subsequent snacking opportunity an hour later. Together, these findings suggest that variations in oral processing across a range of unmodified everyday meals can affect fullness after consuming a fixed portion and can also impact meal size. Modifying food form to encourage increased oral processing (albeit to a lesser extent than in experimental manipulations) might represent a viable target for food manufacturers to help to nudge consumers to manage their weight.

To examine whether television viewing, computer game playing or book reading during meals predicts meal skipping with the aim of watching television, playing computer games or reading books (media meal skipping). A cross-sectional study was conducted using a standardized self-administered questionnaire. Analyses were controlled for age, gender and BMI. Data were obtained from a random sample of adolescents in Flanders, Belgium. Seven hundred and ten participants aged 12, 14 and 16 years. Of the participants, 11.8 % skipped meals to watch television, 10.5 % skipped meals to play computer games and 8.2 % skipped meals to read books. Compared with those who did not use these media during meals, the risk of skipping meals in order to watch television was significantly higher for those children who watched television during meals (2.9 times higher in those who watched television during at least one meal a day). The risk of skipping meals for computer game playing was 9.5 times higher in those who played computer games weekly or more while eating, and the risk of meal skipping in order to read books was 22.9 times higher in those who read books during meals less than weekly. The more meals the respondents ate with the entire family, the less likely they were to skip meals to watch television. The use of media during meals predicts meal skipping for using that same medium. Family meals appear to be inversely related to meal skipping for television viewing.

The effect of ionizing radiation on the microbiological, nutritional, chemical and sensory quality of chilled ready-made meals was assessed. The ready meals used for this experimental work are lasagne. Following arrival at the semi-industrial Cobalt 60 irradiation facility, the meals were either left unirradiated or irradiated with doses of 2 or 4 kGy after which they were stored for up to 23 days at 3C. Results showed that 2 or 4 kGy doses of gamma irradiation decreased the total counts of mesophilic aerobic bacteria and increased the shelf-life of lasagne. In terms of nutritional quality, it was found that losses of vitamin A and E due to irradiation treatment were considerable at 4 kGy. Total acidity, and p H, were all well within the acceptable limit for up to one week for ready meals treated with 2 and 4 kGy whereas peroxide index showed high values at 4 kGy. Sensory results showed no significant differences between the non-irradiated and irradiated meals at 2 kGy. However, the results were less promising at 4 kGy since differences were significant.

Full Text Available An experiment was conducted to evaluate the effect of replacing fish meal with grasshopper meal on haematology, blood chemistry and carcass characteristics of growing rabbits. Forty rabbits of mixed breeds, aged 6-10 weeks, were randomly assigned to the dietary treatments in a complete randomized design with eight rabbits per treatment. The rabbits were fed with diets containing 0, 1.25, 2.50, 3.75 and 5% grasshopper meal in diets designated as T1 (control, T2, T3, T4 and T5, respectively. The experimental diets and clean drinking water were supplied ad libitum throughout the experimental period of nine weeks. At the end of the feeding trial, three rabbits per treatment were slaughtered for carcass evaluation, while blood samples were collected for analysis. The result of the experiment showed significant differences (P0.05 on haemoglobin and mean corpuscular haemoglobin concentration (MCHC. The results also revealed significant differences (P0.05 on serum albumin and total protein. The results of carcass characteristics showed significant differences among treatments (P<0.05 for slaughter weight, carcass weight, dressing percentage, skin pelt, tail, feet and abdominal fat. The slaughter weight and carcass weight were better in groups receiving 2.5% grass hopper meal (50% fish meal replacement. From the results, it can be concluded that inclusion of 2.50% grasshopper meal as a replacement for fish meal (50% replacement has no adverse effects on the haematological parameters, serum biochemistry and carcass characteristics of rabbits.

Understanding different patterns of fish consumption is an important component of the assessment of risk from contaminants in fish. While there have been extensive studies of fish consumption in Western cultures, less attention has been devoted to the role of fish and meat in the diets of people in other cultures. A survey of 212 people living in Singapore was conducted to examine the relative importance of fish, shellfish, and other meat in their diets and to ascertain whether there were differences as a function of age, income, education or gender. As expected, fish and shellfish played an important role in their daily diets. On average, people ate fish in about 10 meals a week, chicken for eight meals, and shrimp and pork for about six meals each. While nearly 8% never ate fish, 18% ate fish at all 21 meals a week and over 20% ate shellfish for all 21 meals. Income explained about 14% of the variation in the number of fish meals consumed, and age explained about 8% of the variation in number of chicken meals per week. There were no gender differences in the number of meals of each type. People less than 26 years old ate significantly more pork, chicken, and other meat meals and fewer shellfish meals than older people. People with higher incomes ate significantly more fish meals than those with lower incomes. Chinese individuals ate significantly more meals of pork, chicken, and other meat than other ethnic groups, and they ate only 26% of their meals at home, while others ate 33% of their meals at home. The data indicate a great deal of variation in the number of meals of fish, shellfish, and other meats eaten by the people interviewed, making dietary and risk assessments challenging

The absorption from iron tablets given with 5 types of meals was studied in 153 subjects. The meals were: a hamburger meal with beans and potatoes, a simple breakfast meal, a Latin American meal composed of black beans, rice and maize and two Southeast Asian meals composed of rice, vegetables, and spices served with and without fish. The groups were directly compared by relating the absorption from the iron tablets to the absorption from a standardized reference dose of iron given on an empty stomach. The composition of meals with respect to content of meat or fish or the presence of large amounts of phytates seemed to have no influence on the absorption of iron from tablets. The absorption from iron tablets was about 40% higher when they were given with rice meals than when they were given with the other meals studied. The average decrease in absorption by meals was about 50-60% based on a comparison when tablets were given on an empty stomach. When tablets from which the iron was released more slowly were used, the absorption increased by about 30% except when they were given with rice meals, where the absorption was unchanged. The differences among the meals in their effect on the absorption of iron from tablets thus disappeared when the slow-release tablets were given. (author)

Innovative approaches to childhood obesity prevention are warranted in early care and education (ECE) settings, since intervening early among youth is recommended to promote and maintain healthy behaviors. The objective of the Meals for Good pilot was to explore feasibility of implementing a food bank-based catering model to ECE programs to provide more nutritious meals, compared to meals brought from home (a parent-prepared model). In 2014-2015, a 12-month project was implemented by a food bank in central Florida in four privately-owned ECE programs. An explanatory sequential design of a mixed-methods evaluation approach was utilized, including a pre-post menu analysis comparing parent-prepared meals to the catered meals, and stakeholder interviews to determine benefits and barriers. The menu analysis of lunches showed daily reductions in calories, fat, and saturated fat, but an increase in sodium in catered meals when compared to parent-prepared meals. Interviews with ECE directors, teachers, parents, and food bank project staff, identified several benefits of the catered meals, including healthfulness of meals, convenience to parents, and the ECE program's ability to market this meal service. Barriers of the catered meals included the increased cost to parents, transportation and delivery logistics, and change from a 5 to a 2-week menu cycle during summer food service. This pilot demonstrated potential feasibility of a food bank-ECE program partnership, by capitalizing on the food bank's existing facilities and culinary programming, and interest in implementing strategies focused on younger children. The food bank has since leveraged lessons learned and expanded to additional ECE programs.

Studies were made on a number of samples of fish meal heavily contaminated (several foci of infection per sample, corresponding 'more than 100% contamination') with salmonella. A dose of 0.7 Mrad proved to be sufficient to inactivate all salmonellaes in all samples. The apparently reduced effect of radiation after artificial contamination of the meal was due to the extreme super-infection. Inactivation curves showed that the salmonella strains used for artificial contamination were more susceptible than those in naturally infected fish meal. Calculation of the slope parameter for a single salmonella type enables the dose of radiation needed to ensure freedom of the meal from salmonella to be determined for each level of infection. With two naturally infected fish meals which contained a total of 18 different serotypes a mean slope parameter of b = -1.99 was calculated which met the requirements posed by the problem of freeing meal from salmonella.

The current study describes the relationships between family meals and family connectedness, parental monitoring and parent-child communication and determines if frequent family meals are associated with better mental well-being and fewer risk-taking behaviours among adolescents. Data were collected as part of Youth'07, a nationally representative survey of the health and well-being of secondary school students in New Zealand (n = 9107). Frequent family meals were positively associated with better indicators of family relationships (P family meals were significantly associated with higher well-being scores (P family connectedness, parental monitoring and parental communication. Our findings suggest that family meals may provide a unique opportunity for building stronger families and young people. Creating environments where frequent family meals are normative, valued and feasible for families may result in benefits for young people that extend beyond good nutrition. © 2013 The Authors.

To compare the nutritional value of meals provided by companies participating in the Workers' Meal Program in the city of São Paulo, Brazil, to the nutritional recommendations and guidelines established by the Ministry of Health for the Brazilian population. The 72 companies studied were grouped according to economic sector (industrial, services, or commerce), size (micro, small, medium, or large), meal preparation modality (prepared on-site by the company itself, on-site by a hired caterer, or off-site by a hired caterer), and supervision by a dietitian (yes or no). The per capita amount of food was determined based on the lunch, dinner, and supper menus for three days. The nutritional value of the meals was defined by the amount of calories, carbohydrates, protein, total fat, polyunsaturated fat, saturated fat, trans fat, sugars, cholesterol, and fruits and vegetables. Most of the menus were deficient in the number of fruits and vegetables (63.9%) and amount of polyunsaturated fat (83.3%), but high in total fat (47.2%) and cholesterol (62.5%). Group 2, composed of mostly medium and large companies, supervised by a dietician, belonging to the industrial and/or service sectors, and using a hired caterer, on averaged served meals with higher calorie content (P<0.001), higher percentage of polyunsaturated fat (P<0.001), more cholesterol (P=0.015), and more fruits and vegetables (P<0.001) than Group 1, which was composed of micro and small companies from the commercial sector, that prepare the meals themselves on-site, and are not supervised by a dietitian. Regarding the nutrition guidelines set for the Brazilian population, Group 2 meals were better in terms of fruit and vegetable servings (P<0.001). Group 1 meals were better in terms of cholesterol content (P=0.05). More specific action is required targeting company officers and managers in charge of food and nutrition services, especially in companies without dietitian supervision.

Full Text Available Abstract Tilapia, salmon, tuna and sardine meals were prepared to develop and analyze extruded snacks with residue meal from fish processing. Residue meals were included in five types of corn snacks: control (0% fish meal and four with 9% tilapia, salmon, tuna and sardine meals. Although moisture, lipids and carbohydrates rates did not differ among the snacks, protein rates increased with the increment of fish meal, reaching 11.85% in the tuna snack. Tuna and sardine snacks had the highest iron levels. The most abundant fatty acids were linoleic, oleic, palmitic, linolenic and stearic acids, with sardine, salmon and tuna snacks presenting the highest values of n-3 series fatty acids. Greater luminosity rate was reported for salmon snack, followed by tilapia, tuna and sardine snacks. The highest sensory acceptance index was verified in tilapia (78.07% and salmon (72.40%. A 9% addition of residue meals of tilapia, salmon and tuna improved the nutritional value of the snacks.

Class and eating: Family meals in Britain.

Science.gov (United States)

Jarosz, Ewa

2017-09-01

This paper examines social differentiation in eating patterns in Britain. It focuses on family meals among individuals with under-age children. Eating with family members has been associated with improvement in wellbeing, nutritional status, and school performance of the children. Modern lifestyles may pose a challenge to commensal eating for all groups, but the scale of the impact varies between social classes, with some groups at higher risk of shortening or skipping family meal time. Eating patterns are differentiated by individual's social class; they have also been associated with educational attainment, work schedules, and household composition. The objective of this study is to disaggregate the effect of these variables. Using data from the 2014/2015 UK Time Use Survey I analyse the net effect of social class, education, income, work and family characteristics on the frequency and duration of family meals. Individuals in the highest occupational class dedicate more time overall to family meals. However, class effect becomes insignificant when other variables, such as education or income, are controlled for. This study finds that higher educated individuals have more frequent family meals, and more affluent individuals spend more time at the table with their household members. Work characteristics are associated with frequency of meals, but not with their duration. Finally, household composition matters for how people eat. Parents of younger children eat with their family members more frequently than parents of teenagers. Single parents, a notoriously time-poor category, spend the least amount of time eating with their families and have fewer commensal meals. Copyright © 2017 Elsevier Ltd. All rights reserved.

Components of postprandial thermogenesis in relation to meal frequency in humans.

Science.gov (United States)

LeBlanc, J; Mercier, I; Nadeau, A

1993-12-01

Experiments on dogs have shown that the size of the meal has no effect on the early cephalic postprandial thermogenesis, and that four small meals are more thermogenic than a larger meal with the same total caloric content as the four meals. A study was repeated on human subjects who were fed during alternating weeks either one large meal (653 kcal (1 kcal = 4.1855 kJ)) or four small meals (163 kcal) at 40-min intervals. Oxygen consumption and respiratory exchange ratio determinations indicated (i) larger overall increase in postprandial thermogenesis with the four meals than with one meal and (ii) an enhancement of glucose utilization with the large meal compared with greater lipid utilization with the four meals. On the basis of indirect evidence from previous investigations it is suggested that the enhanced thermogenesis observed in the four-meal experiment is due to lipid mobilization caused by repeated stimulation of the sympathetic nervous system with palatable food. Blood analysis indicated a reduced elevation of plasma glucose in the four-meal experiment. The variations of insulin and C-peptide exactly paralleled those observed for glucose. It is concluded that the increased frequency of feeding significantly reduces insulin secretion in subjects fed a relatively high carbohydrate meal. In addition to this beneficial effect, increasing the number of meals increased thermogenesis and fat utilization.

Os solos do Agreste paraibano têm baixa fertilidade e a prática usual de adubação é a incorporação de esterco na época do plantio. Entretanto, dependendo da qualidade do esterco, essa prática pode causar a imobilização de nutrientes do solo durante os primeiros meses de cultivo. É possível que o cultivo e incorporação de Crotalaria juncea, combinado com o esterco, possa promover mineralização mais sincronizada com a demanda de nutrientes pelas plantas. No presente estudo, realizado em 2003, f...

Previous researchers have reported that rats placed upon a feeding regimen such that they receive only 2 hr of food per day (meal-fed rats) develop hyperinsulinemia at the time of the day associated with feeding, even in the absence of food. Controls fed ad lib had no such response. In a series of several experiments, meal-fed rats had elevated insulin levels at only the specific time of the day associated with feeding, and the increment of insulin at that time could be eliminated with atropine. Free-feeding controls, on the other hand, always had higher insulin levels than the meal-fed rats, did not have an elevation of insulin at the time of the day that the meal-fed rats normally ate, and had insulin values that were unaffected by atropine. Further experimentation showed that hyperinsulinemia could become associated with arbitrary stimuli always associated with eating for meal-fed rats. It is concluded that the hyperinsulinemia of meal-fed rats associated with their feeding time is a learned response.

To examine and compare the family mealtime environment from the perspectives of both adolescents and parents. Adolescents completed a school-based survey and parents participated in a telephone interview as part of Project EAT (Eating Among Teens). Participants were 902 adolescent females (n=424) and males (n=478) and one of their guardians/parents. Frequencies, chi(2) analyses, and Spearman correlations were used to assess relationships. Parents were more likely than adolescents to report eating five or more family meals per week, the importance of eating together, and scheduling difficulties (Ptogether, and more rule expectations at mealtime (PGirls reported more family meals per week and more scheduling conflicts than boys did; boys reported more rules at mealtime than girls did (Ptogetherness, and for role modeling behaviors that parents would like their children to emulate. Dietetics professionals can capitalize on positive attitudes toward family meals to help promote their frequency. Helping families learn to cook healthful, quick meals may reduce dependency on less healthful meal options, reduce the frequency of eating outside of the home, and promote greater nutritional intake.

Parallel to considerations about settings, selection of the appropriate level of time, effort and care to be put into meal preparation is an important determinant of food choice. Nevertheless, significant relations between the time/energy consumers are willing to devote to food preparation...... and the types of meals they eat are surprisingly hard to find. One explanation for this could be that perceived convenience finds little support on the technological attributes of products like ready meals. This study's aim was to uncover significant relations between perceived convenience, meal preparation...... activities and technological attributes of frozen pizzas. Ninety-eight Dutch meal preparers, 18-29 years old, were asked to rate expected convenience attributes of frozen pizzas; (2) prepare and consume these pizzas in a home-like setting; (3) rate experienced convenience after consumption.

We have previously shown that the postprandial experience includes cognitive sensations, such as satiety and fullness, with a hedonic dimension involving digestive well-being and mood. Preload conditioning has been shown to modulate appetite and food consumption under certain conditions, but its effects on the responses to meal ingestion are not clear. We hypothesized that appetite modulation by preload conditioning has differential effects on the cognitive and the emotive responses to meal ingestion. The effects of preload conditioning (ingestion of a low- vs a high-calorie breakfast) on appetite and on the cognitive and emotive responses to a comfort probe meal ingested 2 hours later (ham and cheese sandwich with orange juice; 300 mL, 425 Kcal) was tested in healthy subjects (n=12) in a cross-over design. Sensations were measured at regular intervals 15 minutes before and 60 minutes after the probe meal. As compared to the low-calorie breakfast, the high-calorie breakfast reduced basal hunger sensation and influenced the responses to the subsequent probe meal: it increased satiety (4.3±0.2 score vs 2.7±0.2 score; PAppetite modulation by preload conditioning has differential effects on the cognitive and emotive responses to a meal.

Yang, Jing-Hua; Zhang, Ming-Fang; Yu, Jing-Quan

2009-02-01

The transcriptional patterns of mitochondrial respiratory related genes were investigated in cytoplasmic male-sterile and fertile maintainer lines of stem mustard, Brassica juncea. There were numerous differences in nad2 (subunit 2 of NADH dehydrogenase) between stem mustard CMS and its maintainer line. One novel open reading frame, hereafter named orfB gene, was located at the downstream of mitochondrial nad2 gene in the CMS. The novel orfB gene had high similarity with YMF19 family protein, orfB in Raphanus sativus, Helianthus annuus, Nicotiana tabacum and Beta vulgaris, orfB-CMS in Daucus carota, atp8 gene in Arabidopsis thaliana, 5' flanking of orf224 in B. napus (nap CMS) and 5' flanking of orf220 gene in CMS Brassica juncea. Three copies probed by specific fragment (amplified by primers of nad2F and nad2R from CMS) were found in the CMS line following Southern blotting digested with HindIII, but only a single copy in its maintainer line. Meanwhile, two transcripts were shown in the CMS line following Northern blotting while only one transcript was detected in the maintainer line, which were probed by specific fragment (amplified by primers of nad2F and nad2R from CMS). Meanwhile, the expression of nad2 gene was reduced in CMS bud compared to that in its maintainer line. We thus suggested that nad2 gene may be co-transcripted with CMS-associated orfB gene in the CMS. In addition, the specific fragment that was amplified by primers of nad2F and nad2R just spanned partial sequences of nad2 gene and orfB gene. Such alterations in the nad2 gene would impact the activity of NADH dehydrogenase, and subsequently signaling, inducing the expression of nuclear genes involved in male sterility in this type of cytoplasmic male sterility.

Infection of mosquitoes is an essential step for the transmission of mosquito-borne arboviruses in nature. Engorgement of infectious blood meals from viremic infected vertebrate hosts allows the entry of viruses and initiates infection of midgut epithelial cells. Historically, the infection process of arboviruses in mosquitoes has been studied through the engorgement of mosquitoes from viremic laboratory animals or from artificial feeders containing blood mixed with viruses harvested from cell cultures. The latter approach using so-called artificial blood meals is more frequently used since it is readily optimized to maximize viral titer, negates the use of animals and can be used with viruses for which there are no small animal models. Use of artificial blood meals has enabled numerous studies on mosquito infections with a wide variety of viruses; however, as described here, with suitable modification it can also be used to study the interplay between infection, specific blood components, and physiological consequences associated with blood engorgement. For hematophagous female mosquitoes, blood is the primary nutritional source supporting all physiological process including egg development, and also influences neurological processes and behaviors such as host-seeking. Interactions between these blood-driven vector biological processes and arbovirus infection that is mediated via blood engorgement have not yet been specifically studied. This is in part because presentation of virus in whole blood inevitably induces enzymatic digestion processes, hormone driven oogenesis, and other biological changes. In this study, the infection process of Zika virus (ZIKV) in Aedes aegypti was characterized by oral exposure via viral suspension meals within minimally bovine serum albumin complemented medium or within whole blood. The use of bovine serum albumin in infectious meals provides an opportunity to evaluate the role of serum albumin during the process of flavivirus

Full Text Available Abstract The aim of this study was to develop pizza dough with different levels of tuna meal (Tunnus spp.. In order to produce tuna meal, tuna torsos without fins were used, cooked for 1 hour, pressed, milled and dehydrated for 24 hours at 60 °C. Pizza dough was produced without (0% or with the addition of 5, 10, 15 and 20% of tuna meal, calculated based on the quantity of wheat flour. The tuna meal and different pizza pastries were analyzed for moisture content, crude protein, total lipids, ash, carbohydrates, caloric value and fatty acid profiles. Microbiological and sensory analyses were also carried out on the pizza pastries. The increasing addition of tuna meal resulted in gains in the crude protein (10.89 to 18.94%, total lipid (4.63 to 5.89% and ash (2.54 to 3.54% contents of the pizza pastries, not influencing the moisture content or caloric value. The inclusion of tuna meal linearly increased the quantity of n-3 series fatty acids in the pizza pastry, from 1.56 to 5.93 g/kg with the addition of 20% tuna meal. The ratio between the polyunsaturated and saturated fatty acids in the tuna meal and pizza pastries varied from 1.21 to 1.85. The microbiological analyses showed that the pizza pastries were produced under proper hygiene conditions. It was also observed that the addition of 5 to 20% of tuna meal to the pizza pastry did not significantly (p>0.05 alter the parameters of aroma, flavor, overall impression and purchase intention. It was therefore concluded that the addition of 5 to 20% tuna meal is effective in improving the nutritional value and fatty acid profile of pizza pastry.

Aversion learning can reduce meal size without taste avoidance in rats.

Nausea and aversive food responses are commonly reported following bariatric surgery, along with post-surgical reduction in meal size. This study investigates whether a meal size limit can be conditioned by associating large meals with aversive outcomes. In rats, the intake of meals exceeding a pre-defined size threshold was paired with lithium chloride-induced gastric illness, and the effects on self-determined food intakes and body weight were measured. Rats given LiCl contingent on the intake of a large meal learned to reliably reduce intake below this meal size threshold, while post-meal saline or LiCl before meals did not change meal size. It was further demonstrated that this is not a conditioned taste aversion and that this effect transferred to foods not explicitly trained. Finally, when rats received LiCl following all large meals, the number of small meals increased, but total food intake and body weight decreased. While further work is needed, this is the first demonstration that meal size may be conditioned, using an aversion procedure, to remain under a target threshold and that this effect is distinct from taste avoidance. Corresponding reduction in food intake and body weight suggests that this phenomenon may have implications for developing weight loss strategies and understanding the efficacy of bariatric surgery. © 2016 The Obesity Society.

To analyze the added sugars in kids' meals from Canadian chain restaurants in relation to the World Health Organization's proposed sugar recommendation (less than 5% of total daily calories should come from added sugars) and current recommendation (less than 10% of total daily calories should come from added sugars). Total sugar levels were retrieved from the websites of 10 fast-food and 7 sit-down restaurants in 2010. The added sugar levels in 3178 kids' meals from Canadian chain restaurants were calculated in 2014 (in Toronto, Canada) by subtracting all naturally occurring sugars from the total sugar level. The average amount of added sugars in restaurant kids' meals (25 ± 0.36 g) exceeded the WHO's proposed daily recommendation for sugar intake. There was a wide range of added sugar levels in kids' meals ranging from 0 g to 114 g. 50% of meals exceeded the WHO's proposed daily sugar recommendation, and 19% exceeded the WHO's current daily sugar recommendation. There is a wide range of sugar levels in kids' meals from restaurants, and many contain more than a day's worth of sugar.

Consumption of fast food and ready-to-eat meals has been positively associated with obesity. In the UK, ready-made meals are more often consumed than in Brazil, a country in which nutrition transition is relatively low. This study aimed to compare the nutritional quality of the main meal consumed by adults in Brazil and UK. Food record data was obtained from representative samples from UK and Brazil databases. The Main Meal Quality Index (MMQI) was applied to estimate the quality of the main meal consumed in Brazil and UK. Differences in food groups consumed in the main meal in Brazil and UK were observed using classification decision tree. Meals with higher average energy content were lunch for Brazil, and dinner for the UK. On average, the Brazilian main meal had better nutritional quality (4.42 times higher), independently of sex, age, family income, nutritional status and energy consumed, with higher scores of fiber, carbohydrate, total fat, saturated fat and energy density. However, UK's main meal included more fruits and vegetables. Food preparations combined with rice and beans were classified as Brazilian main meal, while combinations with fast food items, as fried potatoes, sandwiches and sugary beverages, were classified as UK main meals. In Brazil, the main meal quality was lower among women and obese individuals, presenting significant positive association with age, and negative association with energy intake and family income; while in UK, only age was positively associated with MMQI. Although main meals in Brazil had higher nutritional quality compared to the UK, main meals consumed in both countries need nutritional improvement. Copyright © 2017 Elsevier Ltd.

To identify sociodemographic characteristics associated with frequency of consuming home-cooked meals and meals from out-of-home sources. Cross-sectional analysis of a population-based cohort study. Frequency of consuming home-cooked meals, ready meals, takeaways and meals out were derived from a participant questionnaire. Sociodemographic characteristics regarding sex, age, ethnicity, working overtime and socio-economic status (SES; measured by household income, educational attainment, occupational status and employment status) were self-reported. Sociodemographic differences in higher v. lower meal consumption frequency were explored using logistic regression, adjusted for other key sociodemographic variables. Cambridgeshire, UK. Fenland Study participants (n 11 326), aged 29-64 years at baseline. Eating home-cooked meals more frequently was associated with being female, older, of higher SES (measured by greater educational attainment and household income) and not working overtime. Being male was associated with a higher frequency of consumption for all out-of-home meal types. Consuming takeaways more frequently was associated with lower SES (measured by lower educational attainment and household income), whereas eating out more frequently was associated with higher SES (measured by greater educational attainment and household income) and working overtime. Sociodemographic characteristics associated with frequency of eating meals from different out-of-home sources varied according to meal source. Findings may be used to target public health policies and interventions for promoting healthier diets and dietary-related health towards people consuming home-cooked meals less frequently, such as men, those with lower educational attainment and household income, and overtime workers.

2018-06-01

The impact of timing the consumption of protein supplements in relation to meals on resistance training-induced changes in body composition has not been evaluated systematically. The aim of this systematic review was to assess the effect of consuming protein supplements with meals, vs between meals, on resistance training-induced body composition changes in adults. Studies published up to 2017 were identified with the PubMed, Scopus, Cochrane, and CINAHL databases. Two researchers independently screened 2077 abstracts for eligible randomized controlled trials of parallel design that prescribed a protein supplement and measured changes in body composition for a period of 6 weeks or more. In total, 34 randomized controlled trials with 59 intervention groups were included and qualitatively assessed. Of the intervention groups designated as consuming protein supplements with meals (n = 16) vs between meals (n = 43), 56% vs 72% showed an increase in body mass, 94% vs 90% showed an increase in lean mass, 87% vs 59% showed a reduction in fat mass, and 100% vs 84% showed an increase in the ratio of lean mass to fat mass over time, respectively. Concurrently with resistance training, consuming protein supplements with meals, rather than between meals, may more effectively promote weight control and reduce fat mass without influencing improvements in lean mass.

International Society of Sports Nutrition position stand: meal frequency

Directory of Open Access Journals (Sweden)

Stout Jeffrey R

2011-03-01

Full Text Available Abstract Position Statement: Admittedly, research to date examining the physiological effects of meal frequency in humans is somewhat limited. More specifically, data that has specifically examined the impact of meal frequency on body composition, training adaptations, and performance in physically active individuals and athletes is scant. Until more research is available in the physically active and athletic populations, definitive conclusions cannot be made. However, within the confines of the current scientific literature, we assert that: 1. Increasing meal frequency does not appear to favorably change body composition in sedentary populations. 2. If protein levels are adequate, increasing meal frequency during periods of hypoenergetic dieting may preserve lean body mass in athletic populations. 3. Increased meal frequency appears to have a positive effect on various blood markers of health, particularly LDL cholesterol, total cholesterol, and insulin. 4. Increased meal frequency does not appear to significantly enhance diet induced thermogenesis, total energy expenditure or resting metabolic rate. 5. Increasing meal frequency appears to help decrease hunger and improve appetite control. The following literature review has been prepared by the authors in support of the aforementioned position statement.

The effects of different hydroponic conditions (such as concentration of thorium (Th), pH, carbonate, phosphate, organic acids, and cations) on thorium uptake by Brassica juncea var. foliosa were evaluated. The results showed that acidic cultivation solutions enhanced thorium accumulation in the plants. Phosphate and carbonate inhibited thorium accumulation in plants, possibly due to the formation of Th(HPO4)(2+), Th(HPO4)2, or Th(OH)3CO3 (-) with Th(4+), which was disadvantageous for thorium uptake in the plants. Organic aids (citric acid, oxalic acid, lactic acid) inhibited thorium accumulation in roots and increased thorium content in the shoots, which suggested that the thorium-organic complexes did not remain in the roots and were beneficial for thorium transfer from the roots to the shoots. Among three cations (such as calcium ion (Ca(2+)), ferrous ion (Fe(2+)), and zinc ion (Zn(2+))) in hydroponic media, Zn(2+) had no significant influence on thorium accumulation in the roots, Fe(2+) inhibited thorium accumulation in the roots, and Ca(2+) was found to facilitate thorium accumulation in the roots to a certain extent. This research will help to further understand the mechanism of thorium uptake in plants.

The complex, interacting influences on eating behavior and energy expenditure prevent elucidation of the causal role of any single factor in the current obesity epidemic. However, greater variety in the food supply, particularly in the form of highly palatable, energy-dense foods, has likely made a contribution. This study was undertaken to test the hypothesis that greater dietary variety is associated with greater caloric intake within individual meals consumed by free-feeding, socially-housed female rhesus monkeys. Meal patterns were assessed during two, two-week dietary phases. One phase consisted of a choice between a standard chow diet and a highly palatable diet (HPD). The other phase consisted of access to the chow only. Food intake for each subject was recorded continuously using previously validated, automated feeders, and a meal was defined based on a minimum kilocalorie requirement and a minimum inter-meal interval. During the choice condition, animals electively consumed mixed meals that incorporated both diets as well as other meals that consisted exclusively of a single diet - chow-only or HPD-only. Animals consumed the most calories per meal when the meal was comprised of both the chow and HPD, which differed in caloric density, flavor, and texture. Interestingly, however, there was no significant difference in the amount of calories consumed as HPD-only meals in the choice condition compared to meals in the chow-only, no choice condition, suggesting consumption of a single food during a meal, regardless of palatability, provides a constant sensory experience that may lead to more rapid habituation and subsequent meal cessation. Additionally, during the dietary choice condition, animals consumed fewer calories in the form of chow-only meals. Thus, the present results suggest that limiting dietary variety, regardless of palatability, may be a useful strategy for weight loss in overweight and obese individuals by reducing caloric intake within

Despite research linking family meals to healthier diets, some families are unable to have regular meals together. These families need guidance about other ways to promote healthy eating among adolescents. Our aim was to examine the association between various parenting practices and adolescent fruit and vegetable (F/V) intake at different levels of family meal frequency. We conducted a cross-sectional, population-based survey of influences on adolescent weight-related behaviors using Project EAT (Eating and Activity in Teens) 2010. Participants were 2,491 adolescents recruited from middle/high schools in Minneapolis/St Paul, MN. Adolescent F/V intake was ascertained with a food frequency questionnaire. Survey items assessed frequency of family meals and F/V parenting practices (availability, accessibility, parent modeling, parent encouragement, and family communication). Linear regression models were used to examine associations with and interactions among family meals and parenting practices. Models were adjusted for age, sex, socioeconomic status, race/ethnicity, and energy intake (kilocalories per day). Family meals, F/V availability, F/V accessibility, F/V modeling, and encouragement to eat healthy foods were independently associated with higher F/V intake. Of the 949 (34%) adolescents who reported infrequent family meals (≤2 days/wk), mean F/V intake was 3.6 servings/day for those with high home F/V availability vs 3.0 servings/day for those with low home F/V availability. Similar differences in mean F/V intake (0.3 to 0.6 servings/day) were found for high vs low F/V accessibility, parental modeling, and parent encouragement for healthy eating. Frequent family meals in addition to more favorable parenting practices were associated with the highest F/V intakes. Food parenting practices and family meals are associated with greater adolescent F/V intake. Longitudinal and intervention studies are needed to determine which combination of parenting practices

Full Text Available Abstract Background Data from a dietary-reporting validation study with fourth-grade children were analyzed to investigate a possible relationship of body mass index (BMI with daily participation in school meals and observed energy intake at school meals, and whether the relationships differed by breakfast location (classroom; cafeteria. Methods Data were collected in 17, 17, and 8 schools during three school years. For the three years, six, six, and seven of the schools had breakfast in the classroom; all other schools had breakfast in the cafeteria. Information about 180 days of school breakfast and school lunch participation during fourth grade for each of 1,571 children (90% Black; 53% girls was available in electronic administrative records from the school district. Children were weighed and measured, and BMI was calculated. Each of a subset of 465 children (95% Black; 49% girls was observed eating school breakfast and school lunch on the same day. Mixed-effects regression was conducted with BMI as the dependent variable and school as the random effect; independent variables were breakfast participation, lunch participation, combined participation (breakfast and lunch on the same day, average observed energy intake for breakfast, average observed energy intake for lunch, sex, age, breakfast location, and school year. Analyses were repeated for BMI category (underweight/healthy weight; overweight; obese; severely obese using pooled ordered logistic regression models that excluded sex and age. Results Breakfast participation, lunch participation, and combined participation were not significantly associated with BMI or BMI category irrespective of whether the model included observed energy intake at school meals. Observed energy intake at school meals was significantly and positively associated with BMI and BMI category. For the total sample and subset, breakfast location was significantly associated with BMI; average BMI was larger for

Waakye bought from the open market and 14 meals prepared under the hazard analysis and critical control point (HACCP) plan were microbiologically investigated. The aerobic mesophilic count (AMC) (10 7 - 10 8 CFU g 1 ) and coliform count (10 6 - 10 7 CFU g -1 ) for complete waakye meals, including macaroni, fried fish, sauce and vegetable salad, exceeded the microbiological standards for such ready-to-eat meals. The AMC (10 1 - 10 4 CFU g 1 ) and coliform count (10 1 - 10 2 CFU g -1 ) for all the ready meals prepared under HACCP and stored (-5 to 0 0 C) for up to 5 days were within the standards. Potential pathogens isolated from waakye and the meals prepared under HACCP plan included Escherichia coli, Klebsiella spp., Serratia spp., and Enterobacter spp. Subsequent studies will exploit the potential of irradiation to eliminate pathogens and ensure the microbiological safety of ready-to-eat meals.

A field study was conducted to evaluate crop growth and seed yield performance of Brassica varieties under Rainfed conditions. The varieties, included in the study, were BSA, Zafar-2000, Pakola, Con.1, Con.2, Abaseen, Rainbow, SPS-5, Bard-1, and KJ-119. KJ-119 (2500.0 KG/HA) among Brassica juncea L. varieties and Abaseen (2425.9 kg/ha) among Brassica napusL. Varieties produced with maximum seed yield as compared to rest of varieties. Significantly, minimum seed yield was observed in check variety BSA. The significant difference in seed yield of Brassica varieties, Abaseen and KJ 119, was attributed to improve yield components over other varieties. Maximum pods per plant and seeds per pod led these varieties to attain maximum yield. Inspite of weather variations existence during years 2007-09,the same varieties produced with maximum seed yield.

Kaviani, M; Chilibeck, P D; Yee, P; Zello, G A

2016-01-01

Background/Objectives: Exercise performed shortly before (that is, within half a day of) a high-fat meal is beneficial for stimulating fat oxidation after the meal and reducing postprandial triglycerides (TG). This benefit of exercise is unfortunately negated if the after-exercise food choice to replace the calories expended during exercise is one containing high-glycemic index (HGI) carbohydrates. We determined the effect of consuming low-glycemic index (LGI) carbohydrates after an exercise session on fat oxidation and TG after a subsequent high-fat meal. Subjects/Methods: Using a randomized, counterbalanced crossover design, 23 overweight or obese individuals (body mass index ⩾25 kg m−2) performed: walking exercise (90 min) at 1800 h followed by no meal (EX); exercise followed by a meal with LGI carbohydrates (that is, lentils, EX-LGI); exercise followed by a meal with HGI carbohydrates (that is, instant potatoes, white bread, EX-HGI); and a control condition with no exercise or meal. After a 10-h overnight fast, participants were given a standardized high-fat meal. Fat oxidation was estimated before and for 6 h after this meal from respiratory gas measures and TG determined from blood samples. Results: Fat oxidation (mean±s.d.) was higher with EX (6.9±1.7 g h−1) than EX-HGI (6.3±1.6 g h−1; P=0.007) and Control (5.9±1.7 g h−1; P=0.00002), and EX-LGI (6.6±1.7 g h−1) was higher than Control (P=0.002). TG total area under the curve was 18–32% lower with EX and EX-LGI compared with control (P=0.0005 and P=0.0001, respectively) and EX-HGI (P=0.05 and P=0.021, respectively). Conclusions: A meal containing HGI carbohydrates consumed after an evening exercise session cancels the beneficial effect of exercise for stimulating fat oxidation and lowering TG after a subsequent high-fat meal, whereas consuming a post-exercise meal with LGI carbohydrates retains the positive effect of exercise.

Full Text Available Effect of electron beam irradiation on degradability coefficients and ruminal- postruminal digestibility of dry matter and crude protein of soybean meal, canola meal and Lathyrus sativus seed, irradiated at doses of 50, 100 and 150 kGy was investigated. Ruminal degradability of dry matter and crude protein was determined by in situ method using two cannulated Holstein heifers. Ruminal- postruminal digestibility of dry matter and crude protein was determined by in situ (nylon bag-in vitro (daisy digestor techniques. Data analyzed using SAS software as randomized completely design and the treatment means were compared using Tukey test. The results indicated that irradiation had no effect on dry matter, ether extract and ash content of feeds. In soybean meal, washout fraction and potentially degradable fraction of dry matter and crude protein was higher and lower at dose of 150 kGy irradiation than other treatments, respectively, and degradation rate constant and ruminal effective degradability of dry matter and crude protein was lower at all doses of irradiation than untreated soybean meal. In canola meal, irradiation at doses of 50 and 100 kGy decreased washout fraction and increased potentially degradable fraction of crude protein compared with untreated canola meal. In Lathyrus sativus seed, only potentially degradable fraction of dry matter and crude protein was lower at dose of 150 kGy irradiation than untreated Lathyrus sativus seed. Ruminal digestibility of crude protein decreased in soybean meal at doses of 100 and 150 kGy irradiation and for canola meal at all doses of irradiation than untreated samples. Total tract digestibility of crude protein decreased in soybean meal at dose of 150 kGy irradiation and for canola meal at all doses of irradiation than untreated samples. In Lathyrus sativus seed, ruminal-postruminal digestibility and total tract digestibility of dry matter increased at doses of 100 and 150 kGy irradiation than untreated

Meal consumption and diet quality are important for healthy development during adolescence. The aim of this study was to determine the association between meal habits and diet quality in Brazilian adolescents. A school-based, cross-sectional study was conducted in 2008 with a probabilistic sample of adolescents ages 14 to 19 y (N = 1139) from high schools in central-western Brazil. Consumption of breakfast, morning snack, lunch, afternoon snack, and dinner was assessed to evaluate adolescents' meal profile. The Brazilian Healthy Eating Index-Revised (BHEI-R) was calculated to evaluate diet quality. The association between meal profile and BHEI-R (global estimates and components) was assessed using multivariate linear regression models. Diet was characterized by unhealthy eating: a low consumption of fruits, vegetables, and milk/dairy, and a high consumption of fats and sodium. An unsatisfactory meal profile was observed in 14% of adolescents, whereas daily consumption of breakfast, lunch, and dinner was reported by 47%, 78%, and 52% of adolescents, respectively. Meal profile was positively associated with diet quality. Daily consumption of breakfast was associated with higher BHEI-R scores, lower sodium intake, and greater consumption of fruits and milk/dairy. Daily consumption of lunch was associated with greater consumption of vegetables and "meats, eggs, and legumes," whereas consumption of dinner was associated with an increased consumption of "whole fruits." This study showed a parallelism between daily consumption of meals with healthier eating and greater adherence to traditional Brazilian food habits. Skipping meals was associated with a low-quality diet, especially concerning to the low consumption of fruits and vegetables and a high intake of sodium and calories from solid fats, added sugars, and alcoholic beverages. Therefore, the adoption of regular meal habits may help adolescents improve their diet quality. Copyright © 2017 Elsevier Inc. All

Over-reliance on convenience foods, including ready-meals, has been suggested as one contributor to obesity. Little research has systematically explored the nutritional content of supermarket ready-meals. We described the nutritional content and cost of UK supermarket ready-meals. We conducted a survey of supermarket own-brand chilled and frozen ready-meals available in branches of ten national supermarket chains in one city in northern England. Data on price, weight and nutritional content of meals in four ranges ('healthier', luxury, economy and standard) and of six types (macaroni cheese, meat lasagne, cottage pie, chicken tikka masala, fish pie, and sweet and sour chicken) were collected. Nutritional content was compared to ranges used to identify low, medium and high fat, saturated fat, sugar and salt in nationally recommended front-of-pack labelling. 166 ready-meals were included from 41 stores. Overall, ready-meals were high in saturated fat and salt, and low in sugar. One-fifth of meals were low in fat, saturated fat, salt and sugar, including two-thirds of 'healthier' meals. Meals that were low for three out of the four front-of-pack nutrients were the cheapest. Supermarket ready-meals do not have a healthful nutritional profile overall. However, a number of healthier meals were available - particularly amongst meals specifically marked as 'healthier'. There was little evidence that healthier meals necessarily cost more. Further effort is required to encourage producers to improve the nutritional profile of the full range of ready-meals, and not just those specifically labelled as 'healthier'.

Effect of lime treatment of olive meal on in vitro utilization of total mixed ration containing olive meal as partial maize replacer

Directory of Open Access Journals (Sweden)

Ajmal Ashraf

Full Text Available Aim: Present study pertains to lime treatment of olive meal to improve its digestibility. The objective of the present study was to assess the in vitro dry matter degradability of total mixed ration containing lime treated olive meal at varied levels of maize replacement to know the optimum level of lime and treated olive meal as maize replacement in small ruminant diets. Materials and methods: Study was carried out in two phases. In phase I, A complete diet was formulated and treated with lime at variable concentrations (0-8% at 25% of maize replacement and subjected to in vitro studies as per Tilley and Terry. On the basis of the results of this phase, a concentration of lime for olive treatment was selected and tested at variable levels of maize replacement (0-50% by treated olive cake in phase II. Data was analyzed as per the procedures suggested by Snedecor and Cochran. Results: The in vitro dry matter digestibility (IVDMD of composite diet increased from 43.95% at 0% lime treatment to 48.68% on treating with 8% lime with significant (P<0.05 increase at 6% treatment level. Lime treatment beyond 6% had no further significant effect on improving the digestibility. Graded levels of maize replacement by olive meal treated with 6% lime (lime percentage selected from phase I showed that the in vitro digestibility of mixed ration was not compromised up to 40% replacement level of maize by treated olive meal. Improved digestibility with lime treatment may be due to weakening of internal Hydrogen bonding, thereby disrupting the fiber structure in olive meal. Further lime may be saponifying the high level of fat present in olive meal, which may otherwise negatively impact the digestibility values. Conclusion: It can be concluded that the treatment with up to 6% of lime can effectively increase the digestibility of olive meal. Treated olive meal can replace up to 40% of maize from daily ration without affecting the digestibility of composite ration

Characteristics of parents who purchased kids' meals, reasons for the purchase, and desire for healthy options were examined. Quantitative, cross-sectional study. National. The SummerStyles survey data of 1147 parents (≥18 years). Self-reported outcome variables were purchase of kids' meals (yes/no), reasons for the purchase (13 choices), and desire for healthy options (yes/no). We used multivariable logistic regression to estimate odds ratios (ORs) for purchasing kids' meals based on parental sociodemographic and behavioral characteristics. Over half (51%) of parents reported purchasing kids' meals in the past month. The adjusted OR of purchasing kids' meals were significantly higher among younger parents (OR = 3.44 vs ≥50 years) and among parents who consumed sugar-sweetened beverages (SSBs) daily (OR = 2.70 vs none). No differences were found for race/ethnicity, income, and education. Parents who purchased kids' meals reported that the top 3 reasons for purchase were (1) because their children asked for kids' meals, (2) habit, and (3) offering of healthier sides such as fruits or fruit cups. Thirty-seven percent of parents who did not purchase kids' meals expressed willingness to purchase kids' meals if healthy options were available; this willingness was highest among younger parents (47%; P Kids' meal purchases were somewhat common. Our findings on characteristics of parents who frequently bought kids' meals (ie, younger parents and SSB consumers), common reasons for purchasing kids' meals, and willingness to buy healthier kids' meal can be used to inform intervention efforts to improve quality of kids' meals.
