    Full Text Available Abstract Background A plant-based diet protects against chronic oxidative stress-related diseases. Dietary plants contain variable chemical families and amounts of antioxidants. It has been hypothesized that plant antioxidants may contribute to the beneficial health effects of dietary plants. Our objective was to develop a comprehensive food database consisting of the total antioxidant content of typical foods as well as other dietary items such as traditional medicine plants, herbs and spices and dietary supplements. This database is intended for use in a wide range of nutritional research, from in vitro and cell and animal studies, to clinical trials and nutritional epidemiological studies. Methods We procured samples from countries worldwide and assayed the samples for their total antioxidant content using a modified version of the FRAP assay. Results and sample information (such as country of origin, product and/or brand name were registered for each individual food sample and constitute the Antioxidant Food Table. Results The results demonstrate that there are several thousand-fold differences in antioxidant content of foods. Spices, herbs and supplements include the most antioxidant rich products in our study, some exceptionally high. Berries, fruits, nuts, chocolate, vegetables and products thereof constitute common foods and beverages with high antioxidant values. Conclusions This database is to our best knowledge the most comprehensive Antioxidant Food Database published and it shows that plant-based foods introduce significantly more antioxidants into human diet than non-plant foods. Because of the large variations observed between otherwise comparable food samples the study emphasizes the importance of using a comprehensive database combined with a detailed system for food registration in clinical and epidemiological studies. The present antioxidant database is therefore an essential research tool to further elucidate the potential

  4. An interlaboratory trial on the identification of irradiated spices, herbs, and spice-herb mixtures by thermoluminescence analysis

    International Nuclear Information System (INIS)

    Thermoluminescence analysis was used in an interlaboratory study to detect irradiation treatment of spices, herbs, and spice-herb mixtures in the dose range used for the reduction of microbial counts. About 3 and 9 months after irradiation, 14 participating laboratories determined the thermoluminescence of mineral contaminants that had been isolated from coded samples. A total of 18 different products (6 spices, 6 herbs, and 6 spice-herb mixtures) were examined. The method gave correct identifications as irradiated or nonirradiated in 99.1% of 317 samples. Only 3 irradiated samples were not correctly identified. This result was achieved by integration of whole glow curves. By glow curve analysis, a temperature range could be determined in which differentiation between irradiated and nonirradiated samples was even better than on the basis of the total integral values

    Today, spices are integral part of our food as they provide sensory attributes such as aroma, color, flavour and taste to food. Further their antimicrobial, antioxidant, pharmaceutical and nutritional properties are also well known. Since spices are seasonal so their availability can be extended year round by adopting different preservation techniques. Drying and extraction are most important methods for preservation and value addition to spices. There are different techniques for drying of spices with their own advantages and limitations. A novel, non-conventional technique for drying of spices is use of microwave radiation. This technique proved to be very rapid, and also provide a good quality product. Similarly, there are a number of non-conventional extraction methods in use that are all, in principle, solid-liquid extractions but which introduce some form of additional energy to the process in order to facilitate the transfer of analytes from sample to solvent. This paper reviews latest advances in the use of microwave energy for drying of spices and herbs. Also, the review describes the potential application of microwave energy for extraction of essential oil/bioactive components from spices and herbs and the advantages of microwave-assisted process over the other extraction processes generally employed for extraction. It also showcases some recent research results on microwave drying/extraction from spices and herbs. PMID:25751729

    Full Text Available Spices and herbs have been used as food additives since ancient times, as flavouring agents but also as natural food preservatives. A number of spices shows antimicrobial activity against different types of microorganisms. This article gives a literature review of recent investigations considering antimicrobial activity of essential oils widely used spices and herbs, such as garlic, mustard, cinnamon, cumin, clove, bay, thyme, basil, oregano, pepper, ginger, sage, rosemary etc., against most common bacteria and fungi that contaminate food (Listeria spp., Staphylococcus spp., Salmonella spp., Escherichia spp., Pseudomonas spp., Aspergillus spp., Cladosporium spp. and many others. Antimicrobial activity depends on the type of spice or herb, type of food and microorganism, as well as on the chemical composition and content of extracts and essential oils. Summarizing results of different investigations, relative antimicrobial effectiveness can be made, and it shows that cinnamon, cloves and mustrad have very strong antimicrobial potential, cumin, oregano, sage, thyme and rosemary show medium inhibitory effect, and spices such as pepper and ginger have weak inhibitory effect.

  9. Thermoluminescence analysis to detect irradiated spices, herbs and spice-and-herb mixtures - an intercomparison study. A report in English and German

    International Nuclear Information System (INIS)

    This report describes in detail an inter-laboratory test to detect the irradiation of spices, herbs and spice-and-herb mixtures in the dose range used for reduction of the number of contaminating microorganisms. Approx. 3 months and 9 months after irradiation the 14 participating laboratories determined the thermoluminescence (TL) of mineral contaminations that were isolated from coded samples. 18 different products (six spices, six herbs and six spice-and-herb mixtures) were examined. By whole sample analysis results were obtained in the inter-laboratory test which are typical for this method: Only one non-irradiated sample was classified as irradiated. By contrast, from some spice or herb products (5) all irradiated samples were correctly identified. From other products (3) some irradiated samples could not be identified as irradiated. From the rest of products (4) the majority of the irradiated samples was not identified as irradiated. Therefore, it is not possible to state definitively whether the whole sample method can be recommended as a screening technique. The decision rests with the user. However, data analysis of whole sample measurements revealed that the TL intensities of non-irradiated samples were within the same order of magnitude. Thus, there is no further need for establishing product-specific threshold values. The results make it clear that irradiation of spices, herbs and spice-and-herb mixtures with commercially used doses can be clearly detected by determination of TL signals of contaminating minerals throughout the entire period in which the products are normally stored and that the methods described are suitable for routine analysis in food inspection laboratories.

    2011-05-01

    Full Text Available Abstract Background Worldwide, herbs and spices are much used food flavourings. However, little data exist regarding actual dietary intake of culinary herbs and spices. We developed a food frequency questionnaire (FFQ for the assessment of habitual diet the preceding year, with focus on phytochemical rich food, including herbs and spices. The aim of the present study was to evaluate the intakes of herbs and spices from the FFQ with estimates of intake from another dietary assessment method. Thus we compared the intake estimates from the FFQ with 28 days of estimated records of herb and spice consumption as a reference method. Methods The evaluation study was conducted among 146 free living adults, who filled in the FFQ and 2-4 weeks later carried out 28 days recording of herb and spice consumption. The FFQ included a section with questions about 27 individual culinary herbs and spices, while the records were open ended records for recording of herbs and spice consumption exclusively. Results Our study showed that the FFQ obtained slightly higher estimates of total intake of herbs and spices than the total intake assessed by the Herbs and Spice Records (HSR. The correlation between the two assessment methods with regard to total intake was good (r = 0.5, and the cross-classification suggests that the FFQ may be used to classify subjects according to total herb and spice intake. For the 8 most frequently consumed individual herbs and spices, the FFQ obtained good estimates of median frequency of intake for 2 herbs/spices, while good estimates of portion sizes were obtained for 4 out of 8 herbs/spices. Conclusions Our results suggested that the FFQ was able to give good estimates of frequency of intake and portion sizes on group level for several of the most frequently used herbs and spices. The FFQ was only able to fairly rank subjects according to frequency of intake of the 8 most frequently consumed herbs and spices. Other studies are warranted

  13. Detection of herbs and spices irradiated through optically stimulated luminescence

    International Nuclear Information System (INIS)

    The irradiation of foods is one of the common practices in several countries of the American and European continents. In spite of the widespread use of irradiation methods and technics of nutritious products, it doesn't exist a method of general use at the present time for the detection of previously submitted foods to irradiation with pasteurization ends or sterilization. In the present work the results are presented obtained in the detection of herbs and spices exposed to radiation in the range of 0.1 - 3 KGy, by means of the photostimulation with light of 470 nm. It was used for it a RIS0 model team TL/OSL-GIVE-15 conditioned with a β ray source, 90Sr/90Y and a source of light of 50 mW/cm2. samples of chili guajillo were studied, pepper, cumin, mint and camomile; achieving you to detect exhibitions of the order of 8.33x10-4 KGy that which is indicative of the high sensitivity of the luminescence technique optically stimulated. The answer of the samples with regard to the radiation dose presents a range of lineality for low dose of the order of 0.5 KGy; and supralineal for further dose without to arrive to a saturation stage.

    In the recent years, there has been a growing interest in monitoring heavy metal contamination of spices/herbs. Spices and herbs are sources of many bioactive compounds that can improve the tastes of food as well as influence digestion and metabolism processes. In the present study, the levels of some essential and toxic elements such as iron (Fe), zinc (Zn), copper (Cu), chromium (Cr), manganese (Mn), cobalt (Co), nickel (Ni), lead (Pb), and cadmium (Cd), present in common spices/herbs that were purchased from the local market in Saudi Arabia, were analyzed by atomic absorption spectroscopy after digestion with nitric acid/hydrogen peroxide mixture. Samples from the following spices/herbs were used: turmeric, cloves, black pepper, red pepper, cumin, legume, cinnamon, abazir, white pepper, ginger, and coriander. The concentration ranges for the studied elements were found as 48.8-231, 4.7-19.4, 2.5-10.5, below detection level (BDL)-1.0, 8.8-490, 1.0-2.6, and BDL-3.7 µg g(-1) for Fe, Zn, Cu, Cr, Mn, Ni, and Pb, respectively, while Cd and Co levels were below the detection limit. Consumers of these spices/herbs would not be exposed to any risk associated with the daily intake of 10 g of spices per day as far as metals Fe, Zn, Cu, Cr, Mn, Ni, and Pb are concerned.

Extracts from the medicinal herb and spices have significant activity. B. cereus was the most sensitive and R. mucilaginosa was the most resistant among the microorganisms tested. Ethanolic and methanolic extract of C. asiatica displayed maximum diameter of inhibition zone against bacteria and yeast and percentage mycelial inhibition against moulds. This study confirmed the potential of selected extracts of spices as effective natural food preservative in juices. PMID:26880927

  19. Effect of the most common spices and herbs in typical northwestern Thai diet on human iron absorption

    International Nuclear Information System (INIS)

    The prevalence of iron deficiency anemia in rural Northeast (NE) region is one of the highest in Thailand. The typical NE diets are plant-based. Non-heme iron is the major form in plant source. The bioavailability of non-heme iron depends largely on the presence of enhancers, e.g. ascorbic acid, animal protein, organic acid and inhibitors, e.g. polyphenolic compounds including tannin, phytate in the food matrix of composite meals. The habitual NE Thai dishes consist of a variety of chili dips usually consumed with substantial amount of vegetables and spices. High contents of iron inhibitors such as phytate and polyphenolic compounds including tannin in these herbs and spices may profoundly influence iron bioavailability in the northeast population. However, this inhibitory effect can partially be compensated in vivo by their effect on increasing gastric emptying time and enhancing gastric acid secretion. Although spices and herbs are used in abundance in the developing world and are likely to affect iron absorption in these regions, no systematic investigations in humans have been performed to date. The objective of this study is to evaluate the impact of the most common herbs and spices in typical Northeast diets on human iron absorption by stable isotope techniques. A series of studies will be conducted beginning with the identification of relevant spices and herbs commonly used in Thai habitual diets by 24 hours recall together with food frequency of consumption of popular local dishes. Later, the amount of spices/herbs per serving in popular dishes will be quantified by weighing method followed by the selection of spices/herbs. Food specimens collected in dry and rainy season will be analyzed individually for ascorbic acid, phytate, polyphenol and tannin contents. The three most relevant spices/herbs in the diet will be studied individually. First, the iron absorption from a basic test meal (plain white rice) with and without added spice/herb will be determined

  20. Accumulation of some heavy metals in spice herbs in open-air hydroponics and soil cultures of the Ararat valley

    International Nuclear Information System (INIS)

    Peculiarities of some heavy metals (HM), (Mn, Ni, Ti, V, Co, Cu, Pb, Mo, Cr, Zr) accumulation have been studied in spice herbs (basil, dill, coriander, savory) grown in open-air hydroponics and soil cultures of the Ararat Valley. It turned out that the amount of HM content in spice herbs grown in open-air hydroponic conditions was less than in the ones grown in soil conditions. The content of Pb and Ni in spice herbs exceeded the allowed concentration limits (ACL), especially in soil plants. Practical recommendations on obtaining ecologically safe agricultural products have been prepared. The biotechnological hydroponics method of producing spice herbs in the Ararat Valley is ecologically more beneficial than the soil method. Practical proposals of obtaining ecologically safe agricultural products have been developed

    Full Text Available Ninety-three samples of packaged spices and herbs were collected from different retail shops in Istanbul, Turkey. They were examined for the presence and number of Bacillus cereus. It was determined that fifty-nine samples (63.44% contained more 100 cfu/g of B.cereus, with counts ranging from 102 to 3.2x103 cfu/g. In the 34 samples (36.56%, B.cereus were less 102 cfu/g. Only 5 samples (5.38% had counts between 103-104 cfu/g. The results suggest that incidence of B.cereus was very high in spices and herbs, and therefore should not be ignored in food industry, especially in the meat industry and mass catering establishments.

  3. Analysis of the Detection Characteristics of Irradiated Dried Spices and Herbs by Photostimulated Luminescence (PSL)

    International Nuclear Information System (INIS)

    This study attempted to determine whether Photostimulated Luminescence (PSL) is applicable for the detection of post-irradiated foods by measuring the PSL photon counts of unirradiated and irradiated dried spices and herbs. A total of 19 dried spices and herbs was irradiated with a ∨60Co γ-ray source at 1, 5 and 10 kGy followed by measurement of PSL photon. The photon counts of unirradiated samples below 700 correspond to negative. Fifteen samples irradiated over 1 kGy showed photon counts of more than 5,000, indicating irradiation treatment. Intermediate counts (photon count 700-5,000) were observed in irradiated white/black pepper, nutmeg and cinnamon bark at 10 kGy. These results suggest that it is possible to detect whether dried spices and herbs were irradiated by analyzing PSL, with the exception of white/black pepper, nutmeg and cinnamon bark. Irradiated white/black pepper, nutmeg and cinnamon bark containing low levels of minerals were not sensitive to PSL. Therefore, further investigation is suggested to be performed by Thermoluminescence (TL) analysis or another validated or standardized method

    Full Text Available   Background. Kunun-zakiis an indigenous non alcoholic beverage in Nigeria which has been reported to contain high nutritional values because of the raw materials from which it is made. Therefore, this research was carried out to investigate the antioxidant and antimicrobial activities of extracts of some of the spices used in the production of the beverage. Material  and method. The spices; Xylopia aethiopica (Eru, Syzgium aromaticum (Kanafuru, Monodora myristica(Ariwo, Piper guineensis (Iyere and Piper guineense (Uziza leaf were purchased from local market in Akure, Nigeria. Crude extracts were obtained from the spices using three solvents which include; ethanol, hexane and water. Twenty five g of each spice was soaked in 50 mls of solvent respectively. After evaporation filtrate of water extract and dry extracts of hexane and ethanol were obtained and stored at 4°C until use. The extracts from each of the spices were subjected to screening for their total phenolic content, antioxidant activity and antimicrobial assay using standard methods. Results. Syzgium aromaticum exhibited the highest total phenol content for both the ethanolic (8.75 TAE/g and hexanolic extract (10.73 TAE/g while no phenol was detected from the water extract. The ability of the extracts to bleach the free radical 2,2’-diphenyl-1-picrylhydrazyl (DPPH revealed that the water extracts of the spices possessed better antioxidant properties with values ranged from 58.17-77.53% compared to hexane extracts (44.79-73.87% and ethanol extracts (23.10-47.05%. Contrastly, ethanolic extracts of the spices exhibited best antibacterial activities with inhibition zones of 10.0-27.0 mm and the antifungal activity (11.0-34.0 mm against Aspergillus niger and Aspergillus flavus except for M. myristica that produced no inhibition against A. flavus. Conclusion. It can be deduced from this study that water extracts of the spices investigated may be good antioxidant while ethanol extracts

    Reliability of the photo-stimulated luminescence (PSL) technique, as screening method for irradiated food identification, has been tested with three kinds of herbs and spices (oregano, red pepper and fennel), prepared in two different ways (granular: i.e. seeds and flakes, or powdered), over a long period of storage with different light exposures. The irradiated samples kept in the dark gave always a positive response (the sample is correctly classified as 'irradiated') for the overall examination period. The samples kept under ambient light conditions, in typical commercial glass containers, exhibited a reduction of the PSL signal, more or less pronounced depending on the type of food and packaging. The different PSL response of the irradiated samples is to be related to the quantity and quality of the mineral debris present in the individual food. It was also found that, for the same type of food, the light-induced fading was much stronger for the flaked and seed samples than for the corresponding powder samples, the penetrating capability of light being much more inhibited in powdered than in whole seeds or flaked form samples. The observed light bleaching of the PSL signal in irradiated herbs and spices is of practical relevance since it may lead to false negative classifications.

    Most adults consume more fat than is recommended in the Dietary Guidelines for Americans. We examined whether adding herbs and spices to reduced-fat foods would improve their consumer liking. We recruited adults 18-65 years old to taste three lunch conditions: full fat (FF), reduced fat with no added spice (RF), and reduced fat plus spice (RFS). Subjects rated their liking of a meatloaf entrée, vegetable side dish, pasta side dish, and overall meal on a 9-point hedonic Likert scale. Subjects came weekly for 3 weeks to consume meals and were randomized to the condition order. We enrolled 148 subjects who were predominantly female (n = 101, 68%), had a mean age of 35.9 years, and body mass index of 24.4 kg/m2. Subjects reported habitual diets as 36% of total calories from fat (2005 Block Food Frequency Questionnaire). Reducing fat content alone significantly dropped overall liking of the meal compared with FF and RFS conditions (6.29 RF vs. 7.05 FF, P national guidelines. PMID:24769295

  11. Verification of imported food upon import for radiation processing: Dried herbs, including herbs used in food supplements, and spices by PSL and TL

    International Nuclear Information System (INIS)

    The Italian National Institute of Health in 2005-2006 performed an analytical survey of import on dried spices and herbs, including herbs used in food supplements, to investigate the entry in Italy of irradiated, and not correctly labelled, raw materials. In this survey, 52 samples, including nine herbal extracts, were collected. The method of photo-stimulated luminescence (PSL) was applied to all samples and only samples screened positive or intermediate with PSL were analysed by using the thermo-luminescence (TL) method. Out of the 12 samples screened positive or intermediate with PSL, the TL method confirmed irradiation of five samples (10% of the total assayed samples). One out of these five samples was a herbal supplement whereas three were herbal extracts that are known to be used as ingredients of herbal supplements, and another one was a spice.

    Full Text Available Culinary herbs and spices have long been considered essentially as flavor enhancers or preservatives, with little attention given to their potential health-promoting properties. Nevertheless, recent research has shown them to be significant dietary sources of bioactive phenolic compounds. Despite noteworthy efforts performed in recent years to improve our knowledge of their chemical composition, a detailed phenolic profile of these plant-based products is still lacking. In the present work, antioxidant activities and phenolic composition of five herbs and spices, namely caraway, turmeric, dill, marjoram and nutmeg, have been studied. The use of liquid chromatography coupled to LTQ-Orbitrap mass spectrometry enabled the identification of up to 42 phenolic compounds. To the best of our knowledge, two of them, apigenin-C-hexoside-C-pentoside and apigenin-C-hexoside-C-hexoside have not been previously reported in turmeric. Qualitative and quantitative differences were observed in polyphenol profiles, with the highest phenolic content found in caraway. Multivariate statistical treatment of the results allowed the detection of distinctive features among the studied herbs and spices.

    Advanced glycation endproducts and oxidative stress contribute to the pathogenesis of diabetic complications. The total phenolic content (TPC), antioxidant, and antiglycation properties of crude ethanolic extracts of 10 common culinary herbs and spices from Mauritius were investigated in vitro. Fluorescence at 370 nm/440 nm was used as an index of albumin glycation. Allium sativum had the highest TPC (3.1 mg GAE/mL), whereas Allium cepa L. showed the highest radical scavenging capacity (72%) and Zingiber officinale had the most potent ferric-reducing antioxidant power (FRAP; 2.99 mg AAE/mL). In contrast, Thymus vulgaris and Petroselinum crispum had the most potent antiglycation activity with IC(50) values of 21.8 and 200 mg/mL, respectively. There was no significant correlation between TPC (r=0.001), FRAP (r=0.161), and the antiglycation activity (r=0.034) for the extracts studied. Therefore, the results showed that antiglycation properties of plant-derived extracts cannot always be attributed to their phenolic content or antioxidant potential. PMID:23134460

Cuminum Cyminum (Family: Apiaceae, Nigella sativa (Family: Ranunculaceae, Pimpinella anisum (Family: Apiaceae, Trachyspermum copticum (Family: Umbelliferae, and rhizome of Zingiber officinale (Family: Zingiberaceae were investigated by agar well diffusion method against gram-positive bacteria (Bacillus amyloliquefaciens and Staphylococcus aureus and gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa. The antimicrobial activities of the extracts were assessed by the diameter of zone of inhibition against test strains. The extract of N. sativa showed the best inhibition against S. aureus and P. aeruginosa. The extract of Z. officinale and P. anisum showed same minimum inhibitory concentration (MIC against all the test strains. The extract showed significant inhibitory activity against B. amyloliquefaciens, P. aeruginosa, and S. aureus. The extract of C. cyminum significantly inhibited S. aureus, B. amyloliquefaciens, and P. aeruginosa. The extract of T. copticum was effective against E. coli, B. amyloliquefaciens, and P. aeruginosa, while the highest MIC obtained against S. aureus. The diameters of zone of inhibition obtained for standard antibiotics viz. ampicillin, erythromycin, and tetracycline at MIC values of the extracts were compared with the crude methanolic extracts and found equally or more effective against the test strains. Phytochemical analysis showed carbohydrates, inulin, alkaloids, and glycosides in all the five extracts. Flavonoids, terpenoids, tannins, reducing sugars, soluble phenols, and saponin glycosides were also detected. Steroids were absent. The organoleptic properties of the extracts were determined. The study indicated the great potential of these extracts as effective antimicrobial agents.

    Full Text Available Ethanolic extracts from 23 different dried herbs and spices commercialized in Brazil were investigated for their free radical scavenging properties using the stable free radicals 2,2'-diphenyl-β-picrylhydrazyl (DPPH• and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS•+, and Trolox as reference (TEAC for both radicals. The kinetic curves for both radicals showed to follow the first order kinetics model and the decay rate constant (k obs was calculated. For all the samples, the two methods showed a good linear TEAC correlation, indicating that the average reactivity of the compounds present in the ethanolic extracts was similar. Sage and rosemary extracts showed the highest free radical scavenging capacities, while onion showed negligible activity and colorifico, one of the most consumed spices in Brazil, showed low ABTS•+ scavenging activity. Three distinct situations were found for the extracts concerning the DPPH• scavenging capacities: (1 extracts, like rosemary and laurel, that presented the same efficient concentrations (EC50 but differed in the TEAC values and velocities of action (k obs, (2 extracts, such as garlic and basil, that showed similar EC50 and TEAC values, but different k obs values and (3 extracts that reacted at the same velocities but completely differed in the free radical scavenging capacities, like black pepper, savory, nutmeg, rosemary and sage. Similar considerations could be done for the ABTS•+ results. For the first time the ABTS•+ scavenging activity for allspice, basil, cardamom, chives, colorifico, cumin, dill, laurel, marjoram, parsley and tarragon was reported.Extratos etanólicos de 23 ervas e condimentos desidratados comercializados no Brasil foram analisados quanto as suas propriedades antioxidantes utilizando os radicais 2,2'-difenil-β-picrilhidrazil (DPPH• e ácido 2,2'-azino-bis(3-etilbenzotiazolina-6-sulfônico (ABTS•+, Trolox foi usado como referência para ambos radicais

    The present study was carried out to evaluate the possible synergistic interactions on antibacterial and antioxidant efficacy of essential oils of some selected spices and herbs [bay leaf, black pepper, coriander (seed and leaf), cumin, garlic, ginger, mustard, onion and turmeric] in combination. Antibacterial combination effect was evaluated against six important food-borne bacteria (Bacillus cereus, Listeria monocytogenes, Micrococcus luteus, Staphylococcus aureus, Escherichia coli and Salmonella typhimurium) using microbroth dilution, checkerboard titration and time-kill methods. Antioxidant combination effect was assessed by DPPH free radical scavenging method. Total phenolic content was measured by Folin-Ciocalteu method. Bioactivity –guided fractionation of active essential oils for isolation of bioactive compounds was done using TLC-bioautography assay and chemical characterization (qualitative and quantitative) of bioactive compounds was performed using DART-MS and HPLC analyses. Cytotoxic potential was evaluated by brine shrimp lethality assay as well as MTT assay using human normal colon cell line. Results showed that among the possible combinations tested only coriander/cumin seed oil combination showed synergistic interactions both in antibacterial (FICI : 0.25-0.50) and antioxidant (CI : 0.79) activities. A high positive correlation between total phenolic content and antibacterial activity against most of the studied bacteria (R2 = 0.688 – 0.917) as well as antioxidant capacity (R2 = 0.828) was also observed. TLC-bioautography-guided screening and subsequent combination studies revealed that two compounds corresponding to Rf values 0.35 from coriander seed oil and 0.53 from cumin seed oil exhibited both synergistic antibacterial and antioxidant activities. The bioactive compound corresponding to Rf 0.35 from coriander seed oil was identified as linalool (68.69%) and the bioactive compound corresponding to Rf 0.53 from cumin seed oil was identified

    Objective: To investigate the inhibitory activity of ten culinary herbs and spices namely on glucose-mediated glycation (GMG) and fructose-mediated glycation (FMG) of bovine serum albumin. Methods: Fluorescence was used as an index of albumin glycation using glucose and fructose as substrates in the presence of infusions and ethanolic extracts of ten culinary herbs and spices. Antioxidant activity of the extracts was evaluated using reducing power, metal ion chelating and superoxide radical scavenging assays. Phytochemicals profile was analysed using 13 standard methods. Results: FMG was found to be significantly higher than GMG (95 and 84 AU, respectively; P 0.05) was found in the percentage glycation inhibitory activity of infusions compared to ethanolic extracts. The mean percentage inhibitory activity of the extracts for GMG (45.9%) and for FMG (45.1%) was not significantly different (P > 0.05). Qualitative phytochemical analysis showed the presence of alkaloids, fla-vonoids, tannins, terpenoids, anthraquinones, steroids, reducing sugars, proteins, phenols, saponins, phlobatannins, and cardiac glycosides. Conclusions: The higher rate of fluorescence generation by fructation suggests that glycation by fructose deserves much attention as a glycating agent. Data herein showed that the extracts inhibited GMG and FMG. Thus, these edible plants could be a natural source of antioxidants and anti-glycation agent for preventing advanced glycation end-products-mediated complications.

    The aim of this study was to establish the applicability of natural water-ethanol extracts of herbs and spices in increasing the oxidative stability of plant oils and in the production of novel food. Different concentrations (0, 100, 300, 500, and 700 ppm) of spice extracts and butylated hydroxyanisole (BHA) (100 ppm) were added to the studied oils. The antioxidant activity of spice extracts was determined with electron paramagnetic resonance (EPR) spectroscopy using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical assay. The study showed that the extracts significantly increased the oxidative stability of the examined oils when compared to one of the strongest synthetic antioxidants--BHA. The applied simple production technology and addition of herb and spice extracts to plant oils enabled enhancement of their oxidative stability. The extracts are an alternative to the oils aromatized with an addition of fresh herbs, spices, and vegetables because it did not generate additional flavors thus enabling the maintenance of the characteristic ones. Moreover, it will increase the intake of natural substances in human diet, which are known to possess anticarcinogenic properties. PMID:22900972

    With the aim to expand the olive oil market to a larger number of consumers who are not familiar with the sensory characteristics of virgin olive oil, the use of novel products known as "flavored olive oils", obtained by adding different kind of spices and aromatic herbs, is spreading in many countries. In order to test consumer acceptability of this type of product, in a country (Tunisia) in which virgin olive oil is regularly consumed, flavored olive oils were prepared by adding aromatic extracts of thyme, oregano, a mix of herbs (used as pizza seasoning), rosemary, and basil to a monovarietal Chemlali virgin olive oil and a consumer test on 206 subjects was performed. Selected quality parameters (free acidity, peroxide number, oxidative stability, specific absorption at K232 nm and K270 nm) were also measured and no significant variations were detected. Slight differences were found concerning the content of minor compounds (chlorophylls, carotenoids and total phenols). On the other hand, notable differences were seen in the profiles of volatile compounds, which appeared to be responsible for the observed variability in consumer acceptance. Although the unflavored oil was more appreciated than the flavored ones, among the latter, thyme flavored olive oil was the most appreciated. PMID:27534114

  8. Effect of gamma irradiation on the microbial, chemical quality and the biological activity of some spices and herbs

    International Nuclear Information System (INIS)

    This study was conducted to study the effect of gamma irradiation on both the microbial and the chemical quality of cumin, caraway and Mix Spice Powder (MSP) as well as their antioxidant and antimicrobial activities. Irradiation at 10.0 kGy eliminated yeasts and molds, pathogenic bacteria and reduced the total mesophilic and thermophilic bacteria to the permissible limits of WHO. The storage of the irradiated samples at ambient temperature did not significantly affected its microbial quality. Also ? irradiation at 10.0 kGy significantly decreased moisture content and elevated the peroxide value (PV) of all tested spices. On the other hand, such dose did not change the volatile oil content of cumin and caraway seeds, while it was decreased in the case of MSP. In addition, this treatment resulted in 4.4 % reduction in total amino acids of caraway; it resulted in an increase of 3.5 and 4.1 % in case of cumin and MSP, respectively. GLC analysis of essential oils showed irradiation (10.0 kGy) resulted in 2.9 % and 4.4 % loss in the total volatile oil components of cumin and MSP, respectively. On the other hand, such dose did not change in the total volatile oil components of caraway seeds. The storage at ambient temperature for one year of the studied spices (irradiated and non-irradiated) resulted in a decrease in all of the studied chemical properties except peroxide value (PV) which showed gradual increase by extending the storage. The application of the essential oil of cumin, caraway and MSP (200 ppm) compared with BAH and BHT showed significant delay in the oxidation rate in sunflower oil and enhanced the shelf life of the oil. gamma irradiation (10 kGy) showed no significant effect on the antioxidant activity of the essential oil of cumin, caraway and MSP. The antibacterial and antifungal activities of the tested spices and herbs essential oils were studied. Also the minimum inhibitory concentration (MIC) values were recorded for MSP essential oil.

    This paper presents experimental performance of solar drying of rosella flower and chili using roof-integrated solar dryer and also presents modelling of the roof-integrated solar dryer for drying of chili. Field-level tests for deep bed drying of rosella flower and chili demonstrated that drying in the roof-integrated solar dryer results in significant reduction in drying time compared to the traditional sun drying method and the dry product is a quality dry product compared to the quality products in the markets. The payback period of the roof-integrated solar dryer is about 5 years. To simulate the performance of the roof-integrated solar dryer for drying herbs and spices using hot air from roof-integrated solar collectors, two sets of equations were developed. The first set of equations was solved implicitly and the second set of equations was solved explicitly using finite difference technique. The simulated air temperatures at the collector outlet agreed well with the observed air temperatures. Good agreement was also found between experimental and simulated moisture contents. (author)

    The irradiation of foods is one of the common practices in several countries of the American and European continents. In spite of the widespread use of irradiation methods and technics of nutritious products, it doesn't exist a method of general use at the present time for the detection of previously submitted foods to irradiation with pasteurization ends or sterilization. In the present work the results are presented obtained in the detection of herbs and spices exposed to radiation in the range of 0.1 - 3 KGy, by means of the photostimulation with light of 470 nm. It was used for it a RIS0 model team TL/OSL-GIVE-15 conditioned with a {beta} ray source, {sup 90}Sr/{sup 90}Y and a source of light of 50 mW/cm2. samples of chili guajillo were studied, pepper, cumin, mint and camomile; achieving you to detect exhibitions of the order of 8.33x10{sup -4} KGy that which is indicative of the high sensitivity of the luminescence technique optically stimulated. The answer of the samples with regard to the radiation dose presents a range of lineality for low dose of the order of 0.5 KGy; and supralineal for further dose without to arrive to a saturation stage.

    Full Text Available Summary: Inhibition of quorum sensing (QS, a cell density dependent regulation of bacterial virulent gene expression by autoinducers (AI is an attractive strategy for the discovery of novel antimicrobials and overcome antibiotic resistance. Pseudomonas aeruginosa (PAO1, an opportunistic pathogen in immune compromised patients is under the regulation of the LasR-RhlR system for its QS mediated development of virulence. Natural products have recently become a promising source for deriving molecules that can potentially inhibit quorum sensing.  Herbs, Spices and Medicinal Plants (HSMP used in Hispanic cultures have been used for treating common ailments for many centuries. However, few studies have investigated its QS related antivirulent activities. Our objective was to determine the ability of 25 popular Hispanic HSMP on the expression of QS regulated virulence factors in PAO1. Effect of these extracts on QS mediated PAO1 virulent factors pyocyanin, elastase, and total proteolytic activity were quantified by standard protocols. Results indicated that several extracts reduced pyocyanin synthesis, with some extracts completely inhibiting its formation and secretion. The extracts that decreased the pyocyanin formation also decreased the expression and activity of elastase and other proteolytic enzymes important for the virulence. We observed that HSMP from Central/South American countries can inhibit QS dependent and independent virulent processes in PA-O1. Further research into the exact mechanism of action can lead to better understanding and discovery of new category of drugs and strategies for the management of PAO1 infections and antimicrobial resistance.   Industrial relevance: Quorum sensing is an important process involved in bacterial survival and infections, recent research has focused on the development of therapeutic agents which prevent or manage bacterial pathogenesis by inhibiting bacterial QS. Inhibition of quorum sensing offers an

    Herbs and spices are used worldwide as food flavoring, thus determination of their identity, origin, and quality is mandatory for safe human consumption. An analysis strategy based on separative (HS-SPME-GC-MS) and non-separative (HS-SPME-MS) approaches is proposed for the volatile fraction of herbs and spices, for quality control and to quantify the aromatic markers with a single analysis directly on the plant material as such. Eight-to-ten lots of each of the following herbs/spices were considered: cloves (Syzygium aromaticum (L.) Merr. & Perry), American peppertree (Schinus molle L.), black pepper and white pepper (Piper nigrum L.), rosemary (Rosmarinus officinalis L.), sage (Salvia officinalis L.) and thyme (Thymus vulgaris L.). Homogeneity, origin, and chemotypes of the investigated lots of each herb/spice were defined by fingerprinting, through statistical elaboration with principal component analysis (PCA). Characterizing aromatic markers were directly quantified on the solid matrix through multiple headspace extraction-HS-SPME (MHS-SPME). Reliable results were obtained with both separative and non-separative methods (where the latter were applicable); the two were in full agreement, RSD% ranging from 1.8 to 7.7% for eugenol in cloves, 2.2-18.4% for carvacrol+thymol in thyme, and 3.1-16.8% for thujones in sage.

  17. Classification and prediction of gamma-irradiation of ten commercial herbs and spices by multivariate evaluation of properties of their extracts

    International Nuclear Information System (INIS)

    Antioxidant activity, dry matter content, extractability, total phenolic compounds content and CIE L*a*b* colour characteristics of methanolic extracts of 10 spices exposed to γ-irradiation doses from 0 kGy (reference) to 30 kGy were evaluated in different time intervals after the irradiation by means of UV-VIS spectrophotometry in order to assess the influence of γ-irradiation and post-irradiation storage on spices quality. Experimental data revealed that γ-irradiation itself did not cause so dramatic changes as the subsequent post-irradiation storage, or, that the changes were, at least, comparable. Multivariate statistical methods (factor analysis, canonical discriminant analysis and kth-nearest neighbour classification) facilitated differentiation of irradiated spices from the corresponding references and γ-radiation dose prediction on the basis of processing of experimentally determined characteristics of their extracts. In case of samples exposed to 0 kGy, 10 kGy and 30 kGy, differentiation and classification correctness higher than 85% was reached. In case of 0 kGy and 30 kGy samples differentiation, for 8 spices absolutely correct recognition was achieved and, for remaining 2 spices, still sufficient recognition correctness of 75% and 92.8%, respectively, was achieved. By the statistical models used, more than 90% correctness of dose prediction was achieved in the majority of cases. (author)

  3. Current problems and future outlook for trade in irradiated spices

    International Nuclear Information System (INIS)

    The JECFI recommended worldwide clearance of irradiated spices, including onion powders, up to 10 kGy in 1980. The Netherlands have been irradiating spices since 1970 and together with Belgium, have thus processed several thousand tonnes. However, since no other European country has cleared irradiated spices, there are still barriers to trade. In the U.S., the FDA regulations allow spice irradiation, up to 30 kGy. However, existing large EtO fumigation systems, and conservatism in the industry (despite stringent government regulations regarding worker exposure to EtO) as well as lack of consumer interest and acceptance due to ignorance and misinformation, have allowed only very slow progress in the U.S. Out of a total of 300,000 tons of spices and aromatic herbs, only about 3000 tons will be irradiated in 1985. In Europe it is expected that about 15-20% of the total spices and herbs will be irradiated in 1985 and about 25% in 1986. Labelling is an issue in the U.S. and may represent another impediment. However, a number of surveys have indicated that proper information and education, and in particular that of the woman consumer, are required to overcome reluctance to introduce this technology.

    Full Text Available Turmeric is an ancient spice derived from the rhizomes of Curcuma longa, which is a member of the ginger family (Zingiberaceae. Also known as ‘Golden Spice of India’ turmeric has been used in India for medicinal purposes for centuries. It has been used in traditional medicine as a household remedy for various diseases, including biliary disorders, anorexia, cough, diabetic wounds, hepatic disorders, rheumatism and sinusitis. In addition to its use as a spice and pigment, turmeric and its constituents mainly curcumin and essential oils shows a wide spectrum of biological actions. These include its anti-inflammatory, antioxidant, anti-carcinogenic, anti-mutagenic, anticoagulant, antifertility, anti-diabetic, antibacterial, antifungal, antiprotozoal, antiviral, anti-fibrotic, anti-venom, antiulcer, hypotensive and hypocholesteremic activities. Modern interest on turmeric started in 1970's when researchers found that the herb may possess anti-inflammatory and antioxidant properties. Safety evaluation studies indicate that both turmeric and curcumin are well tolerated at a very high dose without any toxic effects.

    Science.gov (United States)

    Lampe, Johanna W

    2003-09-01

    Thousands of chemical structures have been identified in plant foods. Many are found in spices. Typically, spices are the dried aromatic parts of plants-generally the seeds, berries, roots, pods, and sometimes leaves-that mainly, but not invariably, grow in hot countries. Given the wide range of botanical species and plant parts from which spices are derived, they can contribute significant variety and complexity to the human diet. In the past, the medicinal uses of spices and herbs were often indistinguishable from their culinary uses, and for good reason: people have recognized for centuries both the inherent value, as well as the potential toxicity, of phytochemicals in relation to human health. Plants have the capacity to synthesize a diverse array of chemicals, and understanding how phytochemicals function in plants may further our understanding of the mechanisms by which they benefit humans. In plants, these compounds function to attract beneficial and repel harmful organisms, serve as photoprotectants, and respond to environmental changes. In humans, they can have complementary and overlapping actions, including antioxidant effects, modulation of detoxification enzymes, stimulation of the immune system, reduction of inflammation, modulation of steroid metabolism, and antibacterial and antiviral effects. Embracing a cuisine rich in spice, as well as in fruit and vegetables, may further enhance the chemopreventive capacity of one's diet. PMID:12936952

  13. Irradiation of spices

    International Nuclear Information System (INIS)

    The problem faced by spice producing countries and by the food industry using these spices as ingredients are facing the problem of their high contamination with pathogenic and non pathogenic microorganisms, which create public health and product-deterioration problems. After discussing the conventional methods of decontamination, which result either in organoleptic losses (heat and extracts) or in toxic residues (fumigants), the advantages of the irradiation treatment are presented. This procedure is direct, simple to administer and control, and highly efficient. Doses of 3-7 kGy have been proven to reduce the microbial load to satisfactory levels, without affecting the organoleptic characteristics, whereas the surviving microflora is more sensitive to the subsequent food processing treatments. Irradiation can be administered in the commercial packages, which leads to considerable energy and personnel savings, while preventing subsequent recontamination. The increasing demand for high microbial quality in spices makes it easier for the food industry to afford the irradiation treatment costs. The wholesomeness of irradiated spices has been demonstrated by a group of experts of WHO, FAO and IAEA, and the treatment has been promulgated by Codex Alimentarius and been cleared by a number of national health authorities, including the U.S. F.D.A. The number of clearances is steadily increasing and so is the commercial use

    The ubiqitous microorganism Enterobacter sakazakii is a rare contaminant of infant formula and may cause severe systemic infection in neonates. So far, other food is not known to cause E. sakazakii-infections. The scarce information about the ecology of E. sakazakii and the uncertainty concerning the source of infection in children and adults warrant a summary of the current knowledge about the presence of this opportunistic microorganism in food other than infant formula. This review systematizes publications on the presence of E. sakazakii in food and beverages until June 2006. Food other than infant formula has been rarely investigated for the presence of E. sakazakii. Nevertheless, this microorganism could be isolated from a wide spectrum of food and food ingredients. E. sakazakii was isolated from plant food and food ingredients like cereal, fruit and vegetables, legume products, herbs and spices as well as from animal food sources like milk, meat and fish and products made from these foods. The spectrum of E. sakazakii-contaminated food covers both raw and processed food. The kind of processing of E. sakazakii-contaminated food was not restricted to dry products. Fresh, frozen, ready-to-eat, fermented and cooked food products as well as beverages and water suitable for the preparation of food, were found to be contaminated by E. sakazakii. Although E. sakazakii-contaminated food do not have general public health significance, measures for prevention should consider the presence of E. sakazakii in food, food ingredients, their processing and preparation as possible source of contamination, colonization or infection.

    Full Text Available Spices have been used in our country cuisines since times immemorial. Their use was mainly due to health benefits as herbs and for the aroma they provided in the food. However, little did we know at that time that these spices also have antimicrobial activity. Today, they stand as giants in ayurvedic medicine with substances like turmeric, cloves and cardamom being used in every house-hold. This paper pertains to the antimicrobial activity of three such spices Cloves, Cinnamon and Cardamom on a gram positive and gram-negative bacteria, Bacillus and Pseudomonas respectively. It was found that clove is better with its antimicrobial activity with the zones of inhibition visible clearly on the Petri plates.

  5. Radiolysis of medicinal herbs

    International Nuclear Information System (INIS)

    Radiolysis of the chief component of 124 types of medicinal herbs has been studied, with the majority stable under gamma irradiation with absorbed dose up to 10 kGy. 16 types of the herbs (12.9%) show radiolytic decomposition at 10 kGy, and 6 types (4.8%) at 5 kGy. No radiolytic decomposition is found at less than 2 kGy. The model system study showed that gamma radiolysis is different from thermohydrolytisis and photolysis and water absorbed on the herbs evidently affects the radiolytic decomposition of the herbs. Pulse and gamma radiolysis of baicalin, 1,8-dihydroxyanthraquinone-β-D-glucoside, glycyrrhizin and corydalis-B showed that some new compounds were formed due to OH radical attack. Fructose and glucose can inhibit the gamma radiolytic decomposition of herbs. Chemical clearance displays fruitful and hopeful prospect to disinfect herbs by gamma ray, with the following measures: 1. keeping the herbs in dry state, 2. making bolus by mixing powdered Chinese medicine with honey, as the latter can inhibit the radiolysis of herbs, 3. reducing the microbiological contamination in producing process and thus, requiring lower applied dose

    Full Text Available Clove may be looked upon as a champion of all the antioxidants known till date. The Oxygen Radical Absorption Capacity (ORAC test is a scale developed by U.S. Department of Agriculture for comparing anti-oxidant activity. The ORAC score, of clove is over 10 million. A drop of clove oil is 400 times more powerful as an anti-oxidant than wolf berries or blueberries. Health benefits from the use of clove have been known over the centuries. It is beneficial as a home remedy in curing several ailments / diseases. In addition to its culinary uses, the clove buds have an abundance of medicinal and recreational uses. The major part of the world’s consumption of the clove spice is in the home kitchens. However, commercial use of the clove is for the production of clove oil that contain active constituents, which possess antioxidant, anti-fungal, anti-viral, anti-microbial, anti-diabetic, anti-inflammatory, antithrombotic, anesthetic, pain reliving and insect repellent properties. Eugenol is the main constituent responsible for the medicinal properties of the clove bud. In the light of above, we thought it worthwhile to compile an up-to-date review article on clove covering its, synonyms, chemical constituents, phytopharmacology and medicinal uses.

    Full Text Available Recently, the natural spices and herbs such as rosemary, oregano, and caraway have been used for the processing of meat products. This study investigates the antioxidant activity of 13 spices commonly used in meat processing plants. The hot water extracts were then used for evaluation of total phenolic content, total flavonoids content and antioxidant activities. Our results show that the hot water extract of oregano gave the highest extraction yield (41.33% whereas mace (7.64% gave the lowest. The DPPH radical scavenging ability of the spice extracts can be ranked against ascorbic acid in the order ascorbic acid > clove > thyme > rosemary > savory > oregano. The values for superoxide anion radical scavenging activities were in the order of marjoram > rosemary > oregano > cumin > savory > basil > thyme > fennel > coriander > ascorbic acid. When compared to ascorbic acid (48.72%, the hydroxyl radical scavenging activities of turmeric and mace were found to be higher (p < 0.001. Clove had the highest total phenolic content (108.28 μg catechin equivalent (CE/g. The total flavonoid content of the spices varied from 324.08 μg quercetin equivalent (QE/g for thyme to 3.38 μg QE/g for coriander. Our results indicate that hot water extract of several spices had a high antioxidant activity which is partly due to the phenolic and flavonoid compounds. This provides basic data, having implications for further development of processed food products.

  10. Essential Oils in Ginger, Hops, Cloves, and Pepper Flavored Beverages-A Review.

    Ameh, Sunday J; Ibekwe, Nneka N; Ebeshi, Benjamin U

    2014-08-28

    ABSTRACT In the West, sugar-based, ginger flavored beverages may contain hops, other flavorings, fruit juices, and varying levels of ethanol. Ginger ales contain 0.5%v/v; ginger beers >0.5%; and alcoholic ginger beers 0.5 ≤ 11%. Ales are carbonated by pressurized CO2, while beers and alcoholic beers are carbonated by yeast or ginger beer plant (GBP). In Africa, grain-based beverages include "fura da nono," "kunu," and "akamu," which are spiced with one or more flavorings including ginger, black pepper, clove, chili pepper, or Aframomum alligator peppers. Spices have flavor because they contain essential oils (EOs), which are composed of aroma-active compounds (AACs). The benefits and toxicities of spices are ascribed to their EOs/AACs contents. Aim: Given the toxic potentials of EOs/AACs vis-à-vis their benefits, this review aimed to investigate the means by which the levels of EOs/AACs in spiced beverages are regulated. Methodology: The benefits and liabilities of key EOs/AACs of spices were identified and described. The methods for assaying them in raw materials and beverages were also identified. Results: There was a dearth of data on the levels of EOs/AACs in both raw and finished goods. Moreover, their assay methods were found to be tedious and costly. The implications of these findings on regulation are discussed. Conclusions: Owing to the practical difficulties in assaying flavors in beverages, both manufacturers and regulators should focus on: (i) the wholesomeness of raw materials; and (ii) good manufacturing practice (GMP). However, studies aimed at developing more robust methods for flavor should continue. PMID:25166889

    2014-01-01

    Full Text Available Formation of glycation products is major factor responsible in complications of diabetes. Worldwide trend is toward the use of natural additives in reducing the complications of diseases. Therefore, there is a growing interest in natural antiglycation found in plants. Herbs and spices are one of the most important targets to search for natural antiglycation from the point of view of safety. This study investigated the ability of some of the spices to inhibit glycation process in a hemoglobin/glucose model system and compared their potency with each other. For this subject the best concentration and time to incubate glucose with hemoglobin was investigated. Then the glycosylation degree of hemoglobin in the presence of extracts by the three concentrations 0.25, 0.5 and 1 μg/ml was measured colorimetrically at 520 nm. Results represent that some of extracts such as wild caraway, turmeric, cardamom and black pepper have inhibitory effects on hemoglobin glycation. But some of the extracts such as anise and saffron have not only inhibitory effects but also aggravated this event and have proglycation properties. In accordance with the results obtained we can conclude that wild caraway, turmeric, cardamom and black pepper especially wild caraway extracts are potent antiglycation agents, which can be of great value in the preventive glycation-associated complications in diabetes.

  15. Decontamination of spices by gamma irradiation

    International Nuclear Information System (INIS)

    Decontamination by gamma irradiation of minor spices such as coriander, fennel, cumin, aniseed, cardamom (large) and ajowan was studied. The bacterial load on these spices ranged from 102 - 105 cfu/g, while the fungal load ranged from 10-103 cfu/g. No microorganisms were detected in samples exposed to radiation and stored up to 12 mo. Though pathogens, such as coliforms, B. cereus and Staphylococci were detected in some samples of spices, their presence was not detected in spices exposed to radiation. A comparison of gas liquid chromatographic profiles indicated no significant change in the quality of volatile oils of these spices. Intra country transportation studies, in collaboration with two national laboratories and a multinational corporation, confirmed our earlier observations regarding retention of quality in several spices following irradiation, transport and storage. Similar results were evident from intercountry collaborative studies with Japan. (author). 10 refs, 6 figs, 10 tabs

  16. Irradiation of grains and spices

    International Nuclear Information System (INIS)

    The efficacy of food irradiation to extend the storage life and improve the hygienic quality of rice, mungbean and spices was tested by direct involvement with related food industries. The test consisted of storage trials of irradiated rice under commercial conditions, market testing of irradiated food, and a trial irradiation of commercial products. A consumer acceptance test was conducted using a group of educated people from 3 universities. To prove the safety of food irradiation conducted under appropriately controlled conditions, additional data on vitamin B content and the physico-chemical properties of irradiated rice, as well as free radical activity in irradiated rice, mungbean and spices were collected during this study. The results indicated that rice packaged in polyethylene pouch and irradiated up to 1 kGy could be stored for more than 1 year without insect damage. The colour of irradiated rice was slightly darker than that of unirradiated control, but was still acceptable. The vitamin B content of rice irradiated with such a dose was not significantly changed. Many food companies have recognized the ability of food irradiation, but this technology is not well understood by the general public. An irradiation dose of 3 kGy can be recommended as maximum dose to decontaminate rice of certain bacteria. Free radicals produced in irradiated rice, mungbean and spice will disappear within 1 month following irradiation. (author). 10 refs, 2 figs, 10 tabs

    NASA's "SPICE"* ancillary information system has gradually become the de facto international standard for providing scientists the fundamental observation geometry needed to perform photogrammetry, map making and other kinds of planetary science data analysis. SPICE provides position and orientation ephemerides of both the robotic spacecraft and the target body; target body size and shape data; instrument mounting alignment and field-of-view geometry; reference frame specifications; and underlying time system conversions. SPICE comprises not only data, but also a large suite of software, known as the SPICE Toolkit, used to access those data and subsequently compute derived quantities-items such as instrument viewing latitude/longitude, lighting angles, altitude, etc. In existence since the days of the Magellan mission to Venus, the SPICE system has continuously grown to better meet the needs of scientists and engineers. For example, originally the SPICE Toolkit was offered only in Fortran 77, but is now available in C, IDL, MATLAB, and Java Native Interface. SPICE calculations were originally available only using APIs (subroutines), but can now be executed using a client-server interface to a geometry engine. Originally SPICE "products" were only available in numeric form, but now SPICE data visualization is also available. The SPICE components are free of cost, license and export restrictions. Substantial tutorials and programming lessons help new users learn to employ SPICE calculations in their own programs. The SPICE system is implemented and maintained by the Navigation and Ancillary Information Facility (NAIF)-a component of NASA's Planetary Data System (PDS). * Spacecraft, Planet, Instrument, Camera-matrix, Events

    Full Text Available The herbal material of Coriandrum sativum is the fruit. Fresh herb is also used as an aromatic spice. The aim of the present study was to evaluate the content and chemical composition of coriander herb obtained at different plant growth stages. Coriander plants were grown in a glasshouse, the herb was harvested at the initial stage of flowering and from regrowing shoots. Essential oil extraction from the herb was performed by the hydrodistillation method, whereas the assessment of the chemical composition – using GC-MS method. The examined material contained 0.17–0.29 ml × 100g-1 of essential oil, depending on the stage of plant development when the harvest was done. 61 (generative phase and 65 (vegetative phase compounds were found in the examined coriander oil. The essential oil from the coriander herb contained the highest amount of aliphatic aldehydes, among which was decanal, E-2-dodecanol and E-2-decenol had the highest percentages. The contents of most aliphatic aldehydes decreased with each subsequent harvest of the herb. In addition to the above-mentioned aliphatic aldehydes, the presence of linalool, phytol, and oleic acid was found in the essential oil extracted from the coriander herb.

    Full Text Available The polyminerals content from commercial dust oregano and paprika were extracted and selected by sizes of < 10, 10-53, 53-74 and 74-149 µm and exposed to gamma radiation at different doses in the range 0.5-45 kGy. The glow curves from these polyminerals show an abroad TL band, centered around 450 K and composed of 9-10 glow peaks as calculated by a deconvolution procedure. The XRD analysis shows a composition of mainly quartz and feldspar, including albite, ortose and clay. The fading behavior can be mainly related to the low temperature peaks of the various minerals contained in the spices. The intensity the TL emission increases as the grain size increases for both spices. The TL properties of the polymineral contain of the spices were analyzed and it is possible to conclude that the polymineral content of both oregano and paprika can be used as efficient and practical way to determine the thermoluminescence dose assessment in herbs and spices exposed to ionizing radiation.

    International Nuclear Information System (INIS)

    An experiment has been carried out to evaluate the quality of irradiated spices packaged in some indigenous packaging materials. Spices used were whole nutmeg (myristica fragrans) and whole white pepper (piper nigrum). The spice samples were packaged in tin containers with or without oxygen absorber and in woven polypropylene (PP) bags, then irradiated at 5 kGy, and despatched from Jakarta to Wagenigen by sea-freight. The shipment was performed in small and commercial size packages. The results showed that irradiation treatment could effectively disinfest and decontaminate spices without altering their chemical composition and sensory properties. PP bags, particularly the one without inner liner, were unable to withstand rough handling and to prevent reinfestation during shipment. Tin containers were able to withstand rough handling and prevent reinfestation. The oxygen absorber used had no effect on microbial count and other parameters of the spices. (author)

    Spices have been widely used as food flavorings and folk medicines for thousands of years. Numerous studies have documented the antioxidant, anti-inflammatory and immunomodulatory effects of spices, which might be related to prevention and treatment of several cancers, including lung, liver, breast, stomach, colorectum, cervix, and prostate cancers. Several spices are potential sources for prevention and treatment of cancers, such as Curcuma longa (tumeric), Nigella sativa (black cumin), Zingiber officinale (ginger), Allium sativum (garlic), Crocus sativus (saffron), Piper nigrum (black pepper) and Capsicum annum (chili pepper), which contained several important bioactive compounds, such as curcumin, thymoquinone, piperine and capsaicin. The main mechanisms of action include inducing apoptosis, inhibiting proliferation, migration and invasion of tumors, and sensitizing tumors to radiotherapy and chemotherapy. This review summarized recent studies on some spices for prevention and treatment of cancers, and special attention was paid to bioactive components and mechanisms of action. PMID:27529277

  15. Medieval European medicine and Asian spices.

    Nam, Jong Kuk

    2014-08-01

    This article aimed to explain the reasons why Asian spices including pepper, ginger, and cinnamon were considered as special and valuable drugs with curative powers in the Medieval Europe. Among these spices, pepper was most widely and frequently used as medicine according to medieval medical textbooks. We analyzed three main pharmacology books written during the Middle Ages. One of the main reasons that oriental spices were widely used as medicine was due to the particular medieval medical system fundamentally based on the humoral theory invented by Hippocrates and Galen. This theory was modified by Arab physicians and imported to Europe during the Middle Ages. According to this theory, health is determined by the balance of the following four humors which compose the human body: blood, yellow bile, black bile, and phlegm. Each humor has its own qualities such as cold, hot, wet, and dry. Humoral imbalance was one of the main causes of disease, so it was important to have humoral equilibrium. Asian spices with hot and dry qualities were used to balance the cold and wet European diet. The analysis of several major medical textbooks of the Middle Ages proves that most of the oriental spices with hot and dry qualities were employed to cure diverse diseases, particularly those caused by coldness and humidity. However, it should be noted that the oriental spices were considered to be much more valuable and effective as medicines than the local medicinal ingredients, which were not only easily procured but also were relatively cheap. Europeans mystified oriental spices, with the belief that they have marvelous and mysterious healing powers. Such mystification was related to the terrestrial Paradise. They believed that the oriental spices were grown in Paradise which was located in the Far East and were brought to the Earthly world along the four rivers flowing from the Paradise. PMID:25223223

    Single-FPGA spatial implementations can provide an order of magnitude speedup over sequential microprocessor implementations for data-parallel, floating-point computation in SPICE model-evaluation. Model-evaluation is a key component of the SPICE circuit simulator and it is characterized by large irregular floating-point compute graphs. We show how to exploit the parallelism available in these graphs on single-FPGA designs with a low-overhead VLIW-scheduled architecture. ...

  17. Detection irradiated shallot (Allium Cepa) and spices using technique of Photo Stimulated Luminescence (PSL)

    International Nuclear Information System (INIS)

    This study was carried out to investigate the effectiveness of Photo Stimulated Luminescence (PSL) in detecting the food that has been irradiated qualitatively and quantitatively. The samples used were onions (Allium Cepa) and spices. The shallots which are from India and Thailand was irradiated using Gamma Cell at dose of 0 kGy, 0.2 kGy, 0.4 kGy and 1.0. While for the spices, there were 10 types of spices used such as powder of paprika, parsley, turmeric, tarragon, coriander, mint leaves, basil, rosemary flower, chives and herbs mixture which was irradiated at the dose of 0 kGy and 8.7 kGy respectively. The result shows that the PSL method could differentiate samples which are irradiated and not irradiated. Even though the PSL value increases proportionally to the radiation dose, the relationship between these two means are not that clearly clarified and needed to be studied furthermore.(author)

  1. Determination of volatiles produced during radiation processing in food and medicinal herbs

    International Nuclear Information System (INIS)

    In order to protect food from pathogenic microorganisms as well as to increase its shelf life while keeping sensorial properties (e.g. odor and taste), once the latter are one of the main properties required by spice buyers, it is necessary to analyze volatile formation from irradiation of medicinal and food herbs. The aim of the present study was to analyze volatile formation from Co irradiation of Laurus Cinnamomum, Piper Nigrum, Origanum Vulgare and Myristica Fragans. Possible changes on the odor of these herbs are evaluated by characterizing different radiation doses and effects on sensorial properties in order to allow better application of irradiation technology. l he samples have been irradiated in plastic packages by making use of a 60Co Gamma irradiator. Irradiation doses of 0, 5, 10, 15, 20 and 25kGy have been tested. For the analysis of the samples, SPME has been applied, while for the analysis of volatile compounds, CG/MS. Spice irradiation has promoted mostly decrease in volatile compounds when doses of 5, 10, 15, 20 and 25kGy were used. For Laurus cinnamomum, the irradiation decreased volatile by nearly 56% and 89.5% respectively, comparing to volatile from a sample which has not been previously irradiated. Differently from other spices analyzed, irradiation on Myristica Fragans has increased volatile compounds except for 4-terpineol. The miristicine (toxic substance when in large quantities, commonly mentioned as narcotic) has increased by nearly 80%. For Origanum Vulgare and Piper Nigrum, significant decrease in volatile compounds have been found, mainly when it comes to 25 kGy irradiation. In general, results indicate loss of sensorial quality of spices. (author)

  2. Decontamination of spices by gamma irradiation

    International Nuclear Information System (INIS)

    Decontamination of spices (onion powder, cardamom, red pepper powder, etc.) used for special types of Bulgarian sausages was investigated. Gamma irradiation (60Co) at doses of 4, 6, 8 and 10 kGy was applied. It was found that the total count of microorganisms in spices was between 1.85.105 and 3.8.107. The largest was the amount of the coliforms and the staphylococci in the onion powder. The cardamom and onion powder were free of coliforms with dose of 4 kGy. The staphylococci were eliminated with doses of 6 kGy. The number of proteolytic microorganisms was decreased but they were isolated from spices irradiated even with 10 kGy. (author)

  3. Trial intercountry shipment of irradiated spices

    International Nuclear Information System (INIS)

    The quality of irradiated whole nutmeg (Myristica fragrans) and whole white pepper (Piper nigrum) packaged in locally available material was evaluated. The spice samples were packaged in tin-containers or woven polypropylene (PP) bags, with or without oxygen absorber in the package, irradiated at 5 kGy, and shipped from Jakarta to Wageningen by sea-freight. The shipment was made in small and in commercial-size packages. Irradiation effectively disinfested and decontaminated spices without altering their chemical composition and sensory properties. (PP) bags, particularly those without an inner liner, did not withstand rough handling and did not prevent reinfestation during shipment. Tin containers did withstand rough handling and prevented re-infestation. The oxygen absorber had no effect on microbial count and the other parameters of the spices. (author). 22 refs, 12 tabs

    Cao, Yiqin; Cen, Zhao-Hui; Wei, Jiao-Long

    2009-12-01

    This paper presents a novel fault diagnosis software (called FDSAC-SPICE) based on SPICE simulator for analog circuits. Four important techniques in AFDS-SPICE, including visual user-interface(VUI), component modeling and fault modeling (CMFM), fault injection and fault simulation (FIFS), fault dictionary and fault diagnosis (FDFD), greatly increase design-for-test and diagnosis efficiency of analog circuit by building a fault modeling-injection-simulationdiagnosis environment to get prior fault knowledge of target circuit. AFDS-SPICE also generates accurate fault coverage statistics that are tied to the circuit specifications. With employing a dictionary diagnosis method based on node-signalcharacters and regular BPNN algorithm, more accurate and effective diagnosis results are available for analog circuit with tolerance.

    2016-11-01

    Fraud in the global food supply chain is becoming increasingly common due to the huge profits associated with this type of criminal activity. Food commodities and ingredients that are expensive and are part of complex supply chains are particularly vulnerable. Both herbs and spices fit these criteria perfectly and yet strategies to detect fraudulent adulteration are still far from robust. An FT-IR screening method coupled to data analysis using chemometrics and a second method using LC-HRMS were developed, with the latter detecting commonly used adulterants by biomarker identification. The two tier testing strategy was applied to 78 samples obtained from a variety of retail and on-line sources. There was 100% agreement between the two tests that over 24% of all samples tested had some form of adulterants present. The innovative strategy devised could potentially be used for testing the global supply chains for fraud in many different forms of herbs. PMID:27211681

    Accurate computer simulation of high speed digital computer circuits and communication circuits requires a multimode approach to simulate both the devices and the interconnects between devices. Classical circuit analysis algorithms (lumped parameter) are needed for circuit devices and the network formed by the interconnected devices. The interconnects, however, have to be modeled as transmission lines which incorporate electromagnetic field analysis. An approach to writing a multimode simulator is to take an existing software package which performs either lumped parameter analysis or field analysis and add the missing type of analysis routines to the package. In this work a traditionally lumped parameter simulator, SPICE, is modified so that it will perform lossy transmission line analysis using a different model approach. Modifying SPICE3E2 or any other large software package is not a trivial task. An understanding of the programming conventions used, simulation software, and simulation algorithms is required. This thesis was written to clarify the procedure for installing a device into SPICE3E2. The installation of three devices is documented and the installations of the first two provide a foundation for installation of the lossy line which is the third device. The details of discussions are specific to SPICE, but the concepts will be helpful when performing installations into other circuit analysis packages.

  12. Quality control and disinfestation of spices for export

    International Nuclear Information System (INIS)

    India is the largest producer, consumer and exporter of spices in the world. Other than a few, all spices are grown in this country. The production is estimated at 2.6 million tonnes with an export of about 0.22 million tonnes valued around US $ 333 million. India's share in the world trade is over 40 % in quantity and 20 % in value. Many spices produced in India face quality problems as in other countries. For identifying quality produce, grade specifications have been introduced for all the important spices. With the liberalization of government controls, compulsory pre-shipment inspection has been withdrawn unless insisted by the buyer abroad. To meet the sanitary and phytosanitary requirements, the Spices Board has taken up a massive programme for upgradation of quality of Indian spices. Logo mark and Spice House Certificates are awarded to those spice exporting units having necessary infrastructure for assuring quality. By now, 6 units have been accredited to ISO 9000. Though different chemical and non-chemical treatments are available for improving hygienic quality, irradiation appears to be a reliable method. However, its wide application in the spice industry depends upon the conviction of the consumers of its safety. Because of the comprehensive programmes taken up for quality improvement of spices, India is confident of exporting spices meeting quality specifications prescribed by the importing countries.

    2015-01-01

    Full Text Available Spices are used for aroma, flavor, colour and preservation of foodstuff. Spices may be derived from many parts of the plant viz bark, buds, flowers, fruits, leaves, rhizomes, roots, seeds and the entire plant. Spices are frequently desiccated, dehydrated, processed or distilled to prepare extracts such as essential oils from the raw spice material. These processing techniques may hamper the nutritional aspect of these spices. Moreover, the pharmacological activity of these spices is also altered by these processing methods. Better nutritional prospect of any natural product helps in proper growth of gums in case of dentistry. The current review tries to focus on the nutritional aspects of four common spices used in dentistry.

    2012-06-01

    Full Text Available The aim of this paper is to report the findings of the study of the routes and the distance traveled by spices from the farming location to the consumer in traditional and organised retailing. This research study is primarily exploratory in nature, and the research instruments include interviews and survey through questionnaires with players in the spice supply chain. The study is to track the spice routes by the retailers for assessing the current state of the supply chain management practices, and evaluate ‘food mileage’ clocked by them. ‘Food miles’ is a relatively recent concept in retailing and result of this study reveals that significant increase in food miles in the case of organised retailers. Longer food miles of spices are an indicator of the shift towards organised retailing. The speed at which spices reach their destination as well as the time taken between any two points was not observed. This is the limitation of this study, and also the scope for further research. The research study is not aimed at finding the factors related to the food mileage.

    Full Text Available Turmeric (Curcuma longa is a small rhizomatous perennial herb belonging to Zingiberaceae family originating from South-Eastern Asia, most probably from India. The plant produces fleshy rhizomes of bright yellow to orange colour in its root system, which are the source of the commercially available spice turmeric. In the form of root powder, turmeric is used for its flavouring properties as a spice, food preservative and food-colouring agent. Turmeric has a long history of use in Ayurvedic medicine as it is credited with a variety of important beneficial properties. Turmeric constituents include the three curcuminoids: Curcumin (diferuloylmethane; the primary constituent and the one responsible for its vibrant yellow colour, demethoxycurcumin and bisdemethoxycurcumin, as well as volatile oils (tumerone, atlantone and zingiberone, sugars, proteins and resins. Several studies using the modern techniques have authenticated turmeric used as anti-inflammatory, antimicrobial, anti-fertility, anticancer, anti-diabetic, antioxidant, hypolipidemic, anti-venom, anti hepato-toxic, nephroprotective, anticoagulant, etc., Most importantly, the plant has shown to possess anti HIV activity which could be of great value to combat AIDS particularly in third world countries. In this present work, we make an overview of the phytochemistry and pharmacological activities of turmeric, showing its importance.

    It is shown that most of the natural products contain minute amounts of wind blown or intruding dust which can be separated and used to identify irradiated spices by measuring its thermoluminescence (TL). The method has several advantages over the use of the whole grains of spices. There is no spurious signal due to oxidation of the organic components, therefore the samples can be heated to higher temperatures at which more stable TL peaks are accessible. As a consequence, the method provides (1) high reliability in identification, (2) an access to a quantitative assessment of the administered dose even after some years, (3) determination of the time elapsed between the food irradiation and the TL readout. Thermoluminescent dust obtained from cumin, green pepper, sage, rosemary, mugwort, lovage, thyme, dill weed, oregano, savory, marjoram and basil is investigated. (author).

  1. Comparative study of thermoluminescence detection methods for irradiated spices

    International Nuclear Information System (INIS)

    The thermoluminescence (TL) detection methods for irradiated spices were compared using spice samples obtained on the Japanese market, irradiated at doses of 1, 5, 10 and 30 kGy and stored for 1 year before analysis. The TL intensities of irradiated spices were stable for 1 year after irradiation. Measurement with whole samples failed to identify irradiated samples. Minerals were separated from spices in sodium tungstate saturated solution and/or sodium polytungstate solution. The TL intensity of minerals which had undergone irradiation was significantly increased for all samples. However, the ranges of TL intensity of irradiated and unirradiated samples overlapped. Clear discrimination has been obtained between the TL ratios of irradiated and unirradiated spices by using normalized measurement with reirradiation. The detection limit in terms of irradiation dose is 1 kGy even in a sample that has been irradiated 1 year prior to analysis. Normalization is the best technique currently available for thermoluminescence analysis to identify irradiated spices

    Herbal remedies are clearly a complementary and alternative modality used frequently by patients with hemato-oncological neoplasias during the course of their specific treatment. This review focuses on the potential safety and efficacy of herbs which are either used often or even on a daily basis by patients with hematological malignancies or indicated in the herbal pharmacopeias utilized by various traditional systems of medicine, in order to improve the well-being of patients with these cancers. Traditional medicine worldwide is a source for ongoing laboratory research related to the activity of herbs on cultured cell lines derived from patients with leukemia, lymphoma, and myeloma. Although the number of clinical studies in the field of hemato-oncology is limited, there appears to be potential efficacy in studies of mistletoe (Viscum album), green tea, Indian and Middle-Eastern spices, and some traditional Chinese, American, and European herbs. In addition to the potential efficacy of herbs, safety issues are also reviewed here, particularly, the documented and potential side effects, herb-drug interactions, and matters of quality control. Based on the above issues, the authors suggest enhancing doctor-patient communication regarding herbal use by adopting a patient-centered attitude based on scientific perspective. PMID:20528250

    The post-harvest shelf life of maximum of fruits and vegetables is very limited due to their perishable nature. In India more then 20-25 percent of fruits and vegetables are spoiled before utilization. Despite being the world's second largest producer of fruits and vegetables, in India only 1.5 percent of the total fruits and vegetables produced are processed. Maximum amounts of fruit and vegetable juices turn bitter after extraction due to conversion of chemical compounds. In spite of being under utilized, the utilization of highly nutritive fruits and vegetables is very limited due to high acidity, astringency, bitterness, and some other factors. While improving flavor, palatability, and nutritive and medicinal value of various fruit juices such as aonla, mango, papaya, pineapple, citrus, ber, pear, apple, watermelon, and vegetables including bottle gourd, carrot, beet root, bitter gourd, medicinal plants like aloe vera and spices can also be used for juice blending. All these natural products are valued very highly for their refreshing juice, nutritional value, pleasant flavor, and medicinal properties. Fruits and vegetables are also a rich source of sugars, vitamins, and minerals. However, some fruits and vegetables have an off flavor and bitterness although they are an excellent source of vitamins, enzymes, and minerals. Therefore, blending of two or more fruit and vegetable juices with spices extract for the preparation of nutritive ready-to-serve (RTS), beverages is thought to be a convenient and economic alternative for utilization of these fruits and vegetables. Moreover, one could think of a new product development through blending in the form of a natural health drink, which may also serve as an appetizer. The present review focuses on the blending of fruits, under-utilized fruits, vegetables, medicinal plants, and spices in appropriate proportions for the preparation of natural fruit and vegetable based nutritive beverages.

Bacteriological tests for total bacterial count were carried out on spices before and after irradiation, but the tests for microfiora were carried out only before irradiation. Total bacterial count decreased in proportion to the level of electron beams. But the decreasing rate for Turmeric, Ginger and Basil was lower compared with that of other spices. The reason seems that rate of contamination by B. pumilus, which is thought as radiation resistant bacteria, was higher on these spices. (author)

  12. Irradiation of spices and frozen seafood

    International Nuclear Information System (INIS)

    A study on the inactivation of microorganisms in spices showed that doses of 6 to 9 kGy of EB (electron beam) or gamma irradiation were required to reduce the total aerobic bacteria to below 103 per gram. However, a small increase of resistance was observed on the inactivation of total aerobic bacteria in many spices in case of EB irradiation. The difference in radiation sensitivity between EB and gamma-rays might be explained by the dose rate effect oxidative damage to microorganisms. On the other hand, a high dose rate of EB irradiation suppressed the increase of peroxide values in spices at high dose irradiation up to 80 kGy. The distribution of pathogenic bacteria in 12 samples of the imported frozen shrimps and the effect of gamma-irradiation on these bacteria were also investigated. A few Vibrio parahaemolyticus, V. mimicus, V. alginolyticus, V. vulnificus, V. fluvialis and Listeria monocytogenes were isolated from many samples. The dose necessary to reduce the vibrio isolates and Aeromonas hydrophila at a level of below 10-4 per gram was about 3 kGy in frozen shrimps, whereas about 3.5 kGy was required for L. monocytogenes and Salmonella typhimurium. In this study, unpleasant off-odor was clearly detected in the non-frozen shrimps irradiated at 2.5 kGy. On the other hand, off-odor was negligible in the frozen product below 5 kGy irradiation. No remarkable changes of peroxide values were also obtained up to 9 kGy of irradiation in the frozen shrimps. (author). 17 refs, 8 figs, 7 tabs

    Full Text Available The impact of pectins and its concentration on probiotic characteristics of the beverages has been studied for developing the formulation and technology of pectin beverages. Samples of sour-milk products with dry pectin (Unipectin OB 700 and liquid one (pectin apple extract is produced by SunLand was made. Sour milk microorganisms and bifidobacteria content were defined. High sour milk microorganisms and bifidobacteria content as well as high rate in souring were revealed in the preparatory samples. However, liquid pectin is easier in use. Consequently, the formulation of pectin extract beverages was developed and optimized by using Mathematical Modeling. The samples of beverages were produced and their quality characteristics were evaluated. An optimal fruit/vegetable fillers / whey ration was defined to get the product which combined balanced micronutrient composition, its functional activities and gustatory qualities. For that a three-factor simplex-centroid design was used. The samples produced according to the design matrix were tasted and evaluated by color, flavor, aroma and consistency according to the ten score points scale. The findings were processed with statistical and graphical analysis. The last one used the construction of ternary graphs with the help of «Statistica 7,0» program that allowed to define the most acceptable ranges of fruit/vegetable fillers / whey components in the beverages: fruit juice – 4-16%; pumpkin juice-4-16%; whey -4%. Chemical composition, organoleptical indicators and physicochemical parameters of ready-to drink beverages were examined. As a result, these beverages have been recommended for school feeding as the source of dietary fiber, minerals and vitamins

  16. Improved SPICE electrical model of silicon photomultipliers

    International Nuclear Information System (INIS)

    The present work introduces an improved SPICE equivalent electrical model of silicon photomultiplier (SiPM) detectors, in order to simulate and predict their transient response to avalanche triggering events. In particular, the developed circuit model provides a careful investigation of the magnitude and timing of the read-out signals and can therefore be exploited to perform reliable circuit-level simulations. The adopted modeling approach is strictly related to the physics of each basic microcell constituting the SiPM device, and allows the avalanche timing as well as the photodiode current and voltage to be accurately simulated. Predictive capabilities of the proposed model are demonstrated by means of experimental measurements on a real SiPM detector. Simulated and measured pulses are found to be in good agreement with the expected results. -- Highlights: • An improved SPICE electrical model of silicon photomultipliers is proposed. • The developed model provides a truthful representation of the physics of the device. • An accurate charge collection as a function of the overvoltage is achieved. • The adopted electrical model allows reliable circuit-level simulations to be performed. • Predictive capabilities of the adopted model are experimentally demonstrated

    The objective of this work was to determine the osmolality of beverages frequently consumed by children and adolescents due to the scarce information available in our country. The samples were grouped as follows: milks; refreshments; beverages based on fruits, vegetables, cereals, and tubers; sport drinks; energizing drinks; oral rehydrating solutions; reconstituted drinks and infusions. A vapor pressure digital osmometer was used, five samples of each beverage from different lots were analyzed. Four osmolality determinations were made on each sample and the average of such values was calculated. When the variation coefficient of the osmolality measurements of the five samples was higher than 10%, five additional samples were analyzed. As many samples as possible were used with breast milk in the time period of the study. Osmolality averages, standard deviation, and the osmolality confidence intervals (95% reliability) were calculated. The osmolality (mmol/kg) of breast milk and that of cow milk were between 273 and 389; refreshments, white, black and flavored colas, and malts ranged between 479-811; and soda and light drinks: 44-62; fresh fruit and commercial drinks (coconut, peach, apple, orange, pear, pineapple, grape, plum, tamarind): 257-1152 and light juices: 274; sports beverages: 367; energizing drinks: 740; drinks based on vegetables and cereals: 213-516; oral rehydrating solutions: 236-397; reconstituted drinks: 145; infusions: 25. Beverages with adequate osmolality levels for children were: milks, light refreshments, soda, fresh and light juices, oral rehydrating, soy, and reconstituted drinks and infusions. PMID:15602899

    2014-12-01

    Full Text Available Garlic and salt spice is widely used in Brazilian cookery, but it has a high sodium content; as high sodium intake has been strongly correlated to the incidence of chronic diseases. This study aimed to develop a garlic and salt spice with reduced sodium intake. Sensory evaluation was conducted by applying the spices to cooked rice. First, the optimal concentration of spice added during rice preparation was determined. Subsequently, seasonings (3:1 were prepared containing 0%, 50% and 25% less NaCl using a mixture of salts consisting of KCl and monosodium glutamate; a seasoning with a 0% NaCl reduction was established as a control. Three formulations of rice with different spices were assessed according to sensory testing acceptance, time-intensity and temporal domain of sensations. The proportions of salts used in the garlic and salt spice did not generate a strange or bad taste in the products; instead, the mixtures were less salty. However, the seasonings with lower sodium levels (F2 and F3 were better accepted in comparison to the traditional seasoning (F1. Therefore, a mixture of NaCl, KCl and monosodium glutamate is a viable alternative to develop a garlic and salt spice with reduced sodium intake.

    "SPICE" is an information system, comprising both data and software, providing scientists with the observation geometry needed to plan observations from instruments aboard robotic spacecraft, and to subsequently help in analyzing the data returned from those observations. The SPICE system has been used on the majority of worldwide planetary exploration missions since the time of NASA's Galileo mission to Jupiter. Along with its "free" price tag, portability and the absence of licensing and export restrictions, its stable, enduring qualities help make it a popular choice. But stability does not imply rigidity-improvements and new capabilities are regularly added. This poster highlights recent additions that could be of interest to planetary scientists.Geometry Finder allows one to find all the times or time intervals when a particular geometric condition exists (e.g. occultation) or when a particular geometric parameter is within a given range or has reached a maximum or minimum.Digital Shape Kernel (DSK) provides means to compute observation geometry using accurately modeled target bodies: a tessellated plate model for irregular bodies and a digital elevation model for large, regular bodies.WebGeocalc (WGC) provides a graphical user interface (GUI) to a SPICE "geometry engine" installed at a mission operations facility, such as the one operated by NAIF. A WGC user need have only a computer with a web browser to access this geometry engine. Using traditional GUI widgets-drop-down menus, check boxes, radio buttons and fill-in boxes-the user inputs the data to be used, the kind of calculation wanted, and the details of that calculation. The WGC server makes the specified calculations and returns results to the user's browser.Cosmographia is a mission visualization program.

    The discovery of bioactive compounds in foods has changed the dietary lifestyle of many people. Cyperus esculentus (tigernut) is highly underutilized in Africa, yet tigernut extract is highly profitable in Europe. This study aims to add value to tigernut extract by revealing its health benefits and food value. In this study, tigernut tubers were germinated or roasted and the extracts were combined with Moringa oleifera extract (MOE) or Hibiscus sabdariffa extract (HSE) and spiced with ginger to produce functional drinks. The drinks were evaluated for physicochemical characteristics, sensory parameters, and antioxidant potentials. The total phenolic content of each beverage was measured by the Folin-Ciocalteu method, and the antioxidant activity of each beverage was determined by the 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid assays. The beverages from the germinated tigernut extracts had the highest titratable acidity and the lowest pH, while beverages containing the roasted tigernut extract had the highest ∘Brix. Germination and roasting significantly enhanced the total phenolic content of the drinks. The beverage containing HSE and germinated tigernut extract had a total phenolic content of 45.67 mg/100 mL gallic acid equivalents, which was significantly higher than the total phenolic content of all other samples. The DPPH inhibition activity of the beverages prepared with germinated tigernut extracts was significantly higher than the DPPH inhibition activity of the beverages prepared with fresh tigernut extract. The taste and overall acceptability of drinks containing the roasted tigernut extract were preferred, while the color and appearance of drinks with the germinated samples were preferred. Roasting or germinating tigernuts before extraction and addition of MOE or HSE extracts is another way to add value and enhance the utilization of tigernuts. PMID:25320721

    International Nuclear Information System (INIS)

    Some spices produced in Argentina ground red pepper, anise, fennel, laurel, paprika, Cayenne pepper, cumin (seed), and mayoram (leaves and flowers), were irradiated to inactivate microbial lead, without causing significant chemical or sensory alterations. They were packed in polyethylene bags of 100 m thickness, and irradiated at the 60Co semi-industrial facility of the Ezeiza Atomic Center, with doses of 7 and 10 kGy, and dose rate of 93.87 Gy/min. Dosimetric data were evaluated with potassium nitrate. Control and irradiated samples were stored at room temperature. Chemical analysis were performed to verify the Argentine Alimentary Codex specifications: water content; essence; total ash; ash insoluble in acid; alcoholic, volatile ether and non-volatile ether extracts; starch; and crude fiber. Besides, colour and volatile substances were analyzed. No differences were found between control and irradiated samples, with the exception of an increase in the total amount of volatiles released by irradiated spices, and a slight colour loss in mayoram. Microbiological determinations consisted of aerobic plate count, yeasts and moulds, coliform bacteria, Salmonella, Staphylococcus aureus, mesophilic and thermophilic sporeformers, enterococci and Clostridium perfringens. Microbial load in control samples oscillated between 103 and 106 microorganisms per gram, and was inhibited with 10 kGy to undetectable level. With 7 kGy, survivors were still detected in: cumin, anise, laurel, red pepper, fennel and paprika. So, the purpose of this work was accomplished with the dose of 10 kGy. Great improvement on the quality of those products which being stored at room temperature are consumed in the raw state, would be attained. (Author)

    International Nuclear Information System (INIS)

    Spices and aromatic herbs are divided into leaves, flowers, bud, seeds bark or dry roots from different plants and it is possible to define them as products of highly flavored vegetal origin that volatize easily when incorporated in small quantities to food products and contribute to its aroma, flavor, color or even to its preservation. Nowadays, people look for its functional properties, bioactive compounds and sensory qualities. A big problem is the reduction of the quantity of these compounds throughout the production chain from the harvest process, storage and distribution. For a long time researchers and industries have concentrated on perfecting the processes of the production chain seeking to guarantee the sanitary and food safety, preserving foodstuffs for a long period and an increase in its lifespan without drastically altering its properties. Due to homemade products and the lack of compliance with good practices in its production chain, the spices can contain a high amount of microbiology causing serious complications to the health of the consumer and the radiation processing is often used for reduce these problems. With this finding, the objectives of this work were: Analyze the oil antifungal properties of spices irradiated with average doses (2.5; 5; 7.5 and 10 kGy); Study the average doses (5 and 10 kGy) and high dose (20 and 30 kGy) effects of gamma radiation 60Co in the bioactive compounds of the spices - cloves, cinnamon and nutmeg; Identify the oils compounds; Identify the volatile compounds in the headspace of the oils and the in natura spices. Identify the compounds of the nonvolatile part of the nutmeg; Identify the chiral compounds of the cinnamon. Comparing the control samples (not irradiated) with the processed at the described doses, regarding the oil antifungal properties it was possible to verify the efficiency and later that the irradiation did not interfered in its efficiency; Regarding to the others tests in this work, the compounds

    International Nuclear Information System (INIS)

    Nowadays, in developed countries the irradiation technology is a process used in food treatments for sterilization and diminishing of the microbiological charge, as well as to extend the storage life. In Mexico, the food irradiation, spices and seasonings has been officially approved since 1995, recognizing as an adequate technological process for foods. Taking advantage of knowledge about solids and due to the natural growth of the spices, herbs, etc. these contain minerals which can providing important information of its radiological history, moreover these type of materials do not degrade them preserving by long time periods. In this work, a methodology for the extraction of poly minerals in foods, such as oregano, guajillo chili, jamaica, arnica and camomile is presented. For obtaining the poly mineral, the samples were treated with an ethanol-water solution, in constant stirring during 12 hours at room temperature depending on the sample under treatment. It was used oxygenated water and distilled for washing and acetone for achieving a good drying. The minerals were processed by gamma radiation in the Nuclear Sciences Institute of the UNAM. The brilliance curves of spices and herbs, using a Tl reader of Harshaw 3500 were obtained, the emissions are located between 60 and 350 Centigrade. Previously the extraction of poly mineral was realized and they were divided in same parts for doses between 2 and 10 KGy, this last value according to the Mexican Official Standard considering a fraction without irradiating as reference. The identification of the mineral fraction by diffraction will complement the composition information. We are grateful to the donation of seasonings samples provided by the Tres Villas Natural Seasonings enterprise, Toluca plant, State of Mexico and the Academic Exchange Office at UNAM. (Author)

    Spices, such as cinnamon, cloves, cardamom, garlic, ginger, cumin, coriander and turmeric are used all over the world as flavouring and colouring ingredients in Indian foods. Previous studies have shown that spices contain variable amounts of total oxalates but there are few reports of soluble oxalate contents. In this study, the total, soluble and insoluble oxalate contents of ten different spices commonly used in Indian cuisine were measured. Total oxalate content ranged from 194 (nutmeg) to 4,014 (green cardamom) mg/100 g DM, while the soluble oxalate contents ranged from 41 (nutmeg) to 3,977 (green cardamom) mg/100 g DM. Overall, the percentage of soluble oxalate content of the spices ranged from 4.7 to 99.1% of the total oxalate content which suggests that some spices present no risk to people liable to kidney stone formation, while other spices can supply significant amounts of soluble oxalates and therefore should be used in moderation.

    2013-05-01

    Full Text Available Herb-herb combinations have been used in Chinese medicine practice for thousands of years, yet scientific evidence of their therapeutic benefits is lacking. With increasing interest in shifting from the one-drug-one-target paradigm to combination therapy or polypharmacy to achieve therapeutic benefits for a number of diseases, there is momentum to explore new knowledge by tapping the past empirical experiences of herb-herb combinations. This review presents an overview of the traditional concept and practice of herb-herb combination in Chinese medicine, and highlights the available scientific and clinical evidence to support the combined use of herbs. It is hoped that such information would provide a lead for developing new approaches for future therapeutic advancement and pharmaceutical product development. Very likely modern technologies combined with innovative research for the quality control of herbal products, identification of active components and understanding of the molecular mechanism, followed by well-designed animal and clinical studies would pave the way in advancing the wealth of empirical knowledge from herb-herb combination to new therapeutic modalities.

    In order to protect food from pathogenic microorganisms as well as to increase its shelf life while keeping sensorial properties (e.g. odor and taste), once the latter are one of the main properties required by spice buyers, it is necessary to analyze volatile formation from irradiation of medicinal and food herbs. The aim of the present study was to analyze volatile formation from Co irradiation of Laurus Cinnamomum, Piper Nigrum, Origanum Vulgare and Myristica Fragans. Possible changes on the odor of these herbs are evaluated by characterizing different radiation doses and effects on sensorial properties in order to allow better application of irradiation technology. l he samples have been irradiated in plastic packages by making use of a {sup 60}Co Gamma irradiator. Irradiation doses of 0, 5, 10, 15, 20 and 25kGy have been tested. For the analysis of the samples, SPME has been applied, while for the analysis of volatile compounds, CG/MS. Spice irradiation has promoted mostly decrease in volatile compounds when doses of 5, 10, 15, 20 and 25kGy were used. For Laurus cinnamomum, the irradiation decreased volatile by nearly 56% and 89.5% respectively, comparing to volatile from a sample which has not been previously irradiated. Differently from other spices analyzed, irradiation on Myristica Fragans has increased volatile compounds except for 4-terpineol. The miristicine (toxic substance when in large quantities, commonly mentioned as narcotic) has increased by nearly 80%. For Origanum Vulgare and Piper Nigrum, significant decrease in volatile compounds have been found, mainly when it comes to 25 kGy irradiation. In general, results indicate loss of sensorial quality of spices. (author)

    Natural substances are generally preferred over chemical ones and are generally seen as healthy. The increasing demand for natural ingredients, improving health and appearance, is also attracting beverages as the fastest growing segment on the functional food market. Functional beverages are launched as fortified water, tea, diary or juices claiming overall nutrition, energy, anti-aging or relaxing effects. The substitution of so called superfruits, such as berries, grapes, or pomegranate delivers an effective range of beneficial compounds, including vitamins, fatty acids, minerals, and anti-oxidants. In this context, new exotic and African fruits could be useful sources in the near future. Teas and green botanicals, such as algae or aloe vera are also rich in effective bioactives and have been used traditionally. The botanical kingdom offers endless possibilities. PMID:19168002

    Full Text Available Curcuma longa (Turmeric, belonging to Zingiberaceae family is one of the most useful herbal medicinal plants. Extensive researches have proven that most of the turmeric activities of the turmeric are due to curcumin. It has various useful properties with antioxidant activities and is useful in conditions such as inflammation, ulcer and cancer. It also has antifungal, antimicrobial renal and hepatoprotective activities. Therefore, it has the potential against various cancer, diabetes, allergies, arthritis, Alzheimer’s disease and other chronic and hard curable diseases. The purpose of this review was to provide a brief summary of the new and current knowledge of the effects of curcumin. The recently published papers in international cites such as PubMed/Medline, Science Citation Index and Google Scholar about turmeric were searched. Recent studies have authenticated the use of turmeric for various diseases especially oxidative stress induced ones such as cancer, diabetes mellitus and inflammatory disorders. It also is used as hepatoprotective, nephroprotective, anticoagulant and anti-HIV to combat AIDS. Curcumin, as a spice, exhibits great promise as a therapeutic agent. It has very low toxicity, too. As the global scenario is now changing towards the use of non-toxic plant products having traditional medicinal use, development of modern drugs from turmeric should be emphasized for the control of various diseases. Further evaluation needs to be carried out on turmeric in order to explore the concealed areas and their practical clinical applications, which can be used for the welfare of mankind.

    Objective: To determine the contribution of total phenolic content (TPC) in glycation inhibitory activity of common tropical medicinal food and spices with potential antioxidative properties. Methods: In vitro glucose-bovine serum albumin (BSA) assay was used. Ethanolic extracts of ten common household condiments/herbs (Allium sativum, Zingiber officinale, Thymus vulgaris, Petroselinum crispum, Murraya koenigii Spreng, Mentha piperita L., Curcuma longa L., Allium cepa L., Allium fistulosum and Coriandrum sativum L.) were evaluated for antioxidative activity by 2,2-diphenyl-2-picrylhydrazyl (DPPH), and ferric reducing antioxidant power (FRAP) and the TPC, flavonoid and tannins content were determined. Results: Findings showed good correlation between TPC/DPPH (r= 0.8), TPC/FRAP (r= 0.8), TPC/Anti-glycation (r=0.9), DPPH/Anti-glycation (r= 0.6), FRAP/Anti-glycation (r = 0.9), Flavonoid/Anti-glycation (r= 0.7) and Tannins/Anti-glycation (r = 0.8) and relatively fair correlation for TPC/Flavonoids (r = 0.5) and TPC/Tannins (r =0.5). Results imply that these plants are potential sources of natural antioxidants which have free radical scavenging activity and might be used for reducing oxidative stress. Conclusions: The positive glycation inhibitory and antioxidative activities of these tropical herbs suggest a possible role in targeting ageing, diabetic complications and oxidative stress related diseases.

    Full Text Available Abstract Background Mexico has seen a very steep increase in child obesity level. Little is known about caloric beverage intake in this country as well as all other countries outside a few high income countries. This study examines overall patterns and trends in all caloric beverages from two nationally representative surveys from Mexico. Methods The two nationally representative dietary intake surveys (1999 and 2006 from Mexico are used to study caloric beverage intake in 17, 215 children. The volume (ml and caloric energy (kcal contributed by all beverages consumed by the sample subjects were measured. Results are weighted to be nationally representative. Results The trends from the dietary intake surveys showed very large increases in caloric beverages among pre-school and school children. The contribution of whole milk and sugar-sweetened juices was an important finding. Mexican pre-school children consumed 27.8% of their energy from caloric beverages in 2006 and school children consumed 20.7% of their energy from caloric beverages during the same time. The three major categories of beverage intake are whole milk, fruit juice with various sugar and water combinations and carbonated and noncarbonated sugared-beverages. Conclusion The Mexican government, greatly concerned about obesity, has identified the large increase in caloric beverages from whole milk, juices and soft drinks as a key target and is initiating major changes to address this problem. They have already used the data to shift 20 million persons in their welfare and feeding programs from whole to 1.5% fat milk and in a year will shift to nonfat milk. They are using these data to revise school beverage policies and national regulations and taxation policies related to an array of less healthful caloric beverages.

    Chimarrão or mate is a popular beverage from South America that is drank with successive infusions. Although yerba mate extracts have been widely studied, few studies have described the extract contents in beverages. Using yerba mate samples from Brazil, Argentina, and Uruguay, we examined the extract chromatographic profiles, total polyphenol content and their capacities to chelate iron. In addition, we analyzed antioxidant activity by examining the ability of the extracts to scavenge DPPH and NO. Our results showed that the amount of extracted compound was highest in yerba mate extract from Uruguay, followed by Argentina, then Brazil. Herbs from all three areas had a significant capacity to inhibit DPPH and NO free radicals. The Brazilian and Uruguayan herbs had an 80% iron chelation capacity (pextractions, while the antioxidant capacity is maintained at significant levels. PMID:27173551

    This study identified key attributes of protein beverages and evaluated effects of priming on liking of protein beverages. An adaptive choice-based conjoint study was conducted along with Kano analysis to gain insight on protein beverage consumers (n = 432). Attributes evaluated included label claim, protein type, amount of protein, carbohydrates, sweeteners, and metabolic benefits. Utility scores for levels and importance scores for attributes were determined. Subsequently, two pairs of clear acidic whey protein beverages were manufactured that differed by age of protein source or the amount of whey protein per serving. Beverages were evaluated by 151 consumers on two occasions with or without priming statements. One priming statement declared "great flavor," the other priming statement declared 20 g protein per serving. A two way analysis of variance was applied to discern the role of each priming statement. The most important attribute for protein beverages was sweetener type, followed by amount of protein, followed by type of protein followed by label claim. Beverages with whey protein, naturally sweetened, reduced sugar and ≥15 g protein per serving were most desired. Three consumer clusters were identified, differentiated by their preferences for protein type, sweetener and amount of protein. Priming statements positively impacted concept liking (P 0.05). Consistent with trained panel profiles of increased cardboard flavor with higher protein content, consumers liked beverages with 10 g protein more than beverages with 20 g protein (6.8 compared with 5.7, P consumer appeal.

    Thermoluminescence (TL) properties of curry powder, a salt containing spice mixture, and three different ground spices, viz. chilli, turmeric and pepper, were compared with TL of table salt. The spices other than curry powder, did not exhibit characteristic TL in the absence of salt. Therefore studies were initiated to develop a simple and reliable method using common salt for distinguishing irradiated spices (10 kGy) from unirradiated ones under normal conditions of storage. Common salt exhibited a characteristic TL glow at 170°C. However, when present in curry powder, the TL glow of salt showed a shift to 208°C. It was further observed that upon storage up to 6 months, the TL of irradiated curry powder retained about 10% of the original intensity and still could be distinguished from the untreated samples. From our results it is evident that common salt could be used as an indicator either internally or externally in small sachets for incorporating into prepacked spices.

  11. Development of a microbiological irradiation detection method for spices

    International Nuclear Information System (INIS)

    In order to judge whether certain spices had been irradiated or not, we examined the possibility of developing a method based on the microbiological examination of spices. We used the total bacteria count in conjunction with the ratio of B. megaterium and B. cereus to the total bacteria count. The examination results of 6 kinds of spices with or without irradiation (black pepper, white pepper, coriander, paprika, ginger and turmeric), were as follows. Total bacteria counts over 10E5 CFU/g indicated that the samples were 'unirradiated'. When the total bacteria count was less than 10E5 CFU/g, and the ratio of B. megaterium and B. cereus to the total count was more than 30%, a history of irradiation of the samples was indicated. When ratios of B. megaterium and B. cereus were less than 30% and the total bacteria count was also less than 10E5 CFU/g, 'uncertainty' of irradiation was indicated. In this case, it would be possible to confirm whether spices were 'unirradiated' or 'irradiated' by using another detection method. This detection method was applicable to other spices except for paprika. The samples judged as 'irradiated' by using this detection method, surely proved to have a history of irradiation treatment

    The aim of this study was to find out the effect of selected spices on chemical and sensorial markers in cakes formulated on rye and light buckwheat flour fortified with spices. Among collection of spices, rye-buckwheat cakes fortified individually with cloves, nutmeg, allspice, cinnamon, vanilla, and spice mix revealed the highest sensory characteristics and overall quality. Cakes fortified with cloves, allspice, and spice mix showed the highest antioxidant capacity, total phenolics, rutin, and almost threefold higher available lysine contents. The reduced furosine content as well as free and total fluorescent intermediatory compounds were observed as compared to nonfortified cakes. The FAST index was significantly lowered in all cakes enriched with spices, especially with cloves, allspice, and mix. In contrast, browning index increased in compare to cakes without spices. It can be suggested that clove, allspice, vanilla, and spice mix should be used for production of safety and good quality cakes. PMID:27386114

    India has been recognized all over the world for spices and medicinal plants. Both exhibit a wide range of physiological and pharmacological properties. Current biomedical efforts are focused on their scientific merits, to provide science-based evidence for the traditional uses and to develop either functional foods or nutraceuticals. The Indian traditional medical systems use turmeric for wound healing, rheumatic disorders, gastrointestinal symptoms, deworming, rhinitis and as a cosmetic. Studies in India have explored its anti-inflammatory, cholekinetic and anti-oxidant potentials with the recent investigations focusing on its preventive effect on precarcinogenic, anti-inflammatory and anti atherosclerotic effects in biological systems both under in vitro and in vivo conditions in animals and humans. Both turmeric and curcumin were found to increase detoxifying enzymes, prevent DNA damage, improve DNA repair, decrease mutations and tumour formation and exhibit antioxidative potential in animals. Limited clinical studies suggest that turmeric can significantly impact excretion of mutagens in urine in smokers and regress precancerous palatal lesions. It reduces DNA adducts and micronuclei in oral epithelial cells. It prevents formation of nitroso compounds both in vivo and in vitro. It delays induced cataract in diabetes and reduces hyperlipidemia in obese rats. Recently several molecular targets have been identified for therapeutic / preventive effects of turmeric. Fenugreek seeds, a rich source of soluble fiber used in Indian cuisine reduces blood glucose and lipids and can be used as a food adjuvant in diabetes. Similarly garlic, onions, and ginger have been found to modulate favourably the process of carcinogenesis. PMID:18296352

  19. Identification of irradiated spices with aid of scintillation counter

    International Nuclear Information System (INIS)

    The aim off the work was to determine how one can identify gamma-irradiated spices with aid of a scintillation counter (LKB/Wallac 1219 RackBeta Spectral) by chemiluminescence measurements. Even though scintillation counters are more sensitive than real luminometers they have not been capable in identifying the irradiated spices after contact with photosensitizer like luminol, isoluminol and lucigenin presumably because the actual chemiluminescence reaction took place before the sample vial reached the measuring range. Whereas it was noticed that the identification of pure, dry allspice, black pepper, white peppar and cardemom was possible without any solutions when there were also present similar unirradiated spices. The identification was possible even after 23 weeks duration depending on the dose of the irradiation (10 kGy or 50 kGy) and the weight of the samples (1 g or 9 g). The duration of the investigation was 23 weeks

    Low-angle scattering of X-rays is characterized by the presence of one or more peaks in the forward direction of scattering. These peaks are due to the interference of photons coherently scattered from the molecules of the medium. Thus these patterns are closely linked to the molecular structure of the investigated medium. In this work, low-angle X-ray scattering (LAXS) profiles of five spices; pimpinella anisum (anise), coriandrum sativum (coriander), cuminum cyminum (cumin), foenculum vulgare (fennel) and nigella sativa (nigella or black cumin) are presented after extensive measurements. It is found that all spices exhibit one characteristic peak at a scattering angle around 10°. This is equivalent to a value x=0.0565 Å -1, where x=sin( θ⧸2)⧸ λ. The full width at half maximum (FWHM) of this peak is found to be characteristic for each type of the investigated spices. The possibility to detect the irradiation of these spices from their LAXS profiles is also examined after 10, 20, 30 and 40 kGy doses of gamma radiation. Except for anise, coriander and cumin at 40 kGy, there are no detectable deviations from the control samples in the scattering profiles of irradiated samples. These results comply with the recommendations of the FDA (US Food and Drug Administration) which defines 30 kGy as the maximum dose for irradiation of spices. The present technique could be used to detect over-irradiation, which causes damage to the molecular structure of some spices.

    Full Text Available The paper addresses a simple and fast new approach to implement Artificial Neural Networks (ANN models for the MOS transistor into SPICE. The proposed approach involves two steps, the modeling phase of the device by NN providing its input/output patterns, and the SPICE implementation process of the resulting model. Using the Taylor series expansion, a neural based small-signal model is derived. The reliability of our approach is validated through simulations of some circuits in DC and small-signal analyses.

    Bacteriological examination of 230 samples of five different unprocessed spices (aligator pepper, red pepper, black pepper, thyme and curry powder) collected randomly from Port Harcourt main markets revealed that the spices were highly contaminated, with bacterial counts ranging from 1.8 x 10(4) to 1.1 x 10(8) per gram. Bacillus cereus was isolated in high numbers in the majority of the 230 samples examined. It was also observed that other Bacillus spp. including B. subtilis, B. polymyxa and B. coagulans occurred in significant numbers. PMID:3275301

    In 2010 the IAU Commission 4 Working Group (WG) on Standardizing Access to Ephemerides and File Format Specification was formed to define a portable standard for planetary ephemeris files. The standard would have to work for all three sources of ephemerides-NASA/JPL, Institut de mécanique céleste de calcul des éphémérides (IMCCE), and Institute of Applied Astronomy (IAA). The WG decided to base its standard on the existing "SPICE"* Spacecraft/Planet kernel (SPK) format.The SPK format was created for use with the "SPICE" information system, used by many scientists and engineers worldwide to compute the geometry needed to plan and analyze data from robotic missions. SPICE is comprised of both data files and associated software, all freely available. SPICE data files, usually referred to as "kernels," provide ephemerides and size, shape and orientation of solar system bodies; spacecraft trajectory and orientation; reference frame specifications and implementations; instrument field-of-view geometry; and time system conversion data.Standard SPICE ephemeris files use the TDB time system-the WG requested SPICE be extended to accommodate ephemerides based on the TCB time system. Extensions were also needed to accommodate the IAA ephemeris representation as well as the integrated difference between coordinate time and proper time in the form of TT-TDB and TCG-TCB.Software to read the SPK kernels defined to accommodate planetary ephemerides is available in the SPICE toolkit, and also in stand-alone kernel readers available from IMCEE and IAA.SPK is also used within the SPICE community for natural satellites, asteroids, and comets. Future IAU discussions might lead to an expansion of the work done for planets to provide more general standards for these bodies.Portions of the research described in this publication was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration

  11. Reduction of the number of germs in spices by radappertization

    International Nuclear Information System (INIS)

    The sterilization by fumigation with ethylene oxide and propylene oxide of ground paprika and spice mixtures used in preserves and meat industry was compared with the radappertization of the same spices. The number of germs including that of spores and moulds was determined. It can be established that irradiation with ionizing radiation (5 kGy) has the same effect on the reduction of the number of germs as sterilization by ethylene oxide. In addition, the side effects of sterilization can be avoided. (V.N.)

  12. Microbiological status and antifungal properties of irradiated spices

    International Nuclear Information System (INIS)

    The bacterial counts of commercially available species were found to be in the range of 102-107/g, whereas the fungal counts varied between 102 and 103/g. Among the five spices studied, pepper, cardamom, and nutmeg mace had a high microbial load compared to cinnamon and clove. Exposure to γ-irradiation in the dose range of 7.5-10 kGy was adequate to sterilize all the spices. The essential oil of clove and cinnamon exhibited inhibitory properties against aflatoxin-producing aspergilli. γ-Irradiation did not affect fungal inhibitory principles present in clove, though marginal reduction was observed in that of cinnamon

  13. SPICE modelling of the transient response of irradiated MOSFETs

    International Nuclear Information System (INIS)

    A new SPICE model of irradiated MOSFET taking into account the real response of the 4 electrodes is proposed.

Body composition, educational and income level, physical activity (PA), and beverage consumption and energy intake were assessed. Sixty-two percent of adolescents engaged in >300 min/week of PA. Boys were more active than girls, younger adolescents were more active than older counterparts, low parental income was associated with physical inactivity, and time spent watching TV (including, TV, Internet or handheld cellular devices) was inversely associated with PA practice. The average beverage intake of the studied adolescents was 0.9 L/day, higher in boys than in girls. Beverage intake was positively associated with PA practice, and the highest amount of energy intake from beverages was observed in active boys and girls. Most of the studied adolescent population met the PA recommendations. Gender, age, parental income, and time spent watching TV were significant determinants of PA. Type and amount of beverages drunk varied according to gender and PA, and general daily total beverage intake was lower than recommended adequate fluid intake. PA behavior should be considered when analyzing beverage consumption in adolescents. PMID:27347993

    Epidemiological and experimental studies have consistently linked alcoholic beverage consumption with the development of several chronic disorders, such as cancer, cardiovascular diseases, diabetes mellitus and obesity. The impact of drinking is usually dose-dependent, and light to moderate drinking tends to lower risks of certain diseases, while heavy drinking tends to increase the risks. Besides, other factors such as drinking frequency, genetic susceptibility, smoking, diet, and hormone status can modify the association. The amount of ethanol in alcoholic beverages is the determining factor in most cases, and beverage types could also make an influence. This review summarizes recent studies on alcoholic beverage consumption and several chronic diseases, trying to assess the effects of different drinking patterns, beverage types, interaction with other risk factors, and provide mechanistic explanations.

    The microbiological quality of 351 samples of nine types of spices including black pepper, caraway, cinnamon, cow parsnip, curry powder, garlic powder, red pepper, sumac, and turmeric, collected from retail shops in Tehran during 2007, was determined. The numbers of aerobic mesophilic bacteria, Escherichia coli, and molds exceeded Iran's National Standard limits, at 63.2% (>5 × 10(5) CFU/g), 23.4% (>0.3 MPN/g), and 21.9% (>5 × 10(3) CFU/g) of the studied samples, respectively. Coliform contamination was more than 10(3) MPN/g in 24.8% of samples. High contamination of retail spices is considered an indication of environmental or fecal contamination due to unhygienic practices in their production. Use of spices with high microbial content could increase the chance of food spoilage and transmission of foodborne pathogens. Accordingly, application of food safety measurements to reduce microbial counts in spices is strongly recommended. PMID:23643126

  6. Bacterial flora of spices and its control by gamma irradiation

    International Nuclear Information System (INIS)

    The bacterial contamination was tested in 26 samples of spices. Chili, allspice and paprika were the most contaminated spices by bacteria. Five bacterial genera were isolated, namely bacillus, staphylococcus, streptococcus, micrococcus, and coccobacillus, all being gram-positive. Most isolates have been related to the genus bacillus. The bacterial isolates were identified as B. alvei, B. circulans, B. megaterium, B. pasteurii, B. pumilus, B. thuringiensis, B. sphaericus, B. incertaesedis, Micrococcus luteus, staphylococcus aureus, streptococcus sp. and coccobacillus sp. Irradiation of spices led to a significant decrease in the bacterial count of all samples. The dose required to inhibit completely the natural bacterial flora was 25 KGY. The most radioresistant isolates were staphylococcus aureus and micrococcus luteus which were subjected to sublethal doses of 15 and 20 KGY respectively. The dose response curves of the 2 most radioresistant isolates showed simple exponential relationship. The D 10-value of S. aureus and M. luteus were 0.9 and 1.1 KGY, respectively. The effect of storage period on the bacterial load of, as well as, the antibacterial activity of the tested spices were investigated. (author)

  7. Thermoluminescence and photo stimulated luminescence measurements on commercial spices

    International Nuclear Information System (INIS)

    Four kinds of commercial spices (white pepper, black pepper, garlic powder and red pepper) were subjected to a novel photo stimulated luminescence (PSL) method and results were compared with those in European Standard (CEN) PSL and thermoluminescence (TL) methods. Three samples of different makers for each spice were purchased from retailers in Tsukuba and Tokyo areas and subjected to the analysis. When the TL ratios of spice sample were greater than 0.1 and a Glow1 maximum was observed in a range of 190-200 deg C, the photon counts in a novel PSL analysis significantly raised just after LED illumination and then gradually decreased. And for these samples the PSL counts by a CEN standard analysis were greater than 5000. On the other hand, the photon counts were almost constant in the samples whose TL ratio was less than 0.1 and a PSL count in a CEN standard analysis was less than 700. The results in the novel PSL method are well consistent with other detection methods, both TL and CEN standard PSL. These results suggest that the novel PSL method is useful for the detection of irradiation in commercial spices

    Background: How beverage taxes might influence purchases of foods and beverages among households with preschool children is unclear. Thus, we examined the relation between beverage taxes and food and beverage purchases among US households with a child 2–5 y of age. Objectives: We examined how a potential tax on sugar-sweetened beverages (SSBs), or SSBs and >1% fat and/or high-sugar milk, would influence household food and beverage purchases among US households with a preschool child. We aimed to identify the lowest tax rate associated with meaningful changes in purchases. Methods: We used household food and beverage purchase data from households with a single child who participated in the 2009–2012 Nielsen Homescan Panel. A 2-part, multilevel panel model was used to examine the relation between beverage prices and food and beverage purchases. Logistic regression was used in the first part of the model to estimate the probability of a food/beverage being purchased, whereas the second part of the model used log-linear regression to estimate predicted changes in purchases among reporting households. Estimates from both parts were combined, and bootstrapping was performed to obtain corrected SEs. In separate models, prices of SSBs, or SSBs and >1% and/or high-sugar milk, were perturbed by +10%, +15%, and +20%. Predicted changes in food and beverage purchases were compared across models. Results: Price increases of 10%, 15%, and 20% on SSBs were associated with fewer purchases of juice drinks, whereas price increases of 10%, 15%, and 20% simulated on both SSBs plus >1% fat and/or high-sugar milk (combined tax) were associated with fewer kilocalories purchased from >1% fat, low-sugar milk, and meat, poultry, fish, and mixed meat dishes. Conclusions: Our study provides further evidence that a tax on beverages high in sugar and/or fat may be associated with favorable changes in beverage purchases among US households with a preschool child.

The aim of the investigation was to identify fungi causing the death of leaf tissues of herbs from the mint family Lamiaceae. In mycological investigations, 180 fragments of each plant leaves (1,080 dead leaf fragments in total were placed in a 2% PDA medium. Over 970 colonies of fungi belonging to 48 species were isolated from the dead leaf tissues of the six herb species. Alternaria alternata (toxin-producing, Epicoccum nigrum and Sordaria fimicola were the most frequently isolated. The largest numbers of colonies and species of fungi were isolated from horsemint, while the lowest numbers were from wild marjoram leaves. It was shown that the death of leaves of selected herb species from the Lamiaceae family was caused by various fungi. The results of the mycological analysis confirmed the diversity of species colonizing the leaves of the herbs.

Here an attempt has been made to review some herbs used for the prevention and treatment of cancer. These herbs were found for posses anticancer, cytotoxic or antioxidant activity in various pre-clinical or clinical studies. Cancer is a disease in which body cells become abnormal and divide without control. Cancer cell may invade nearby tissues and they may spread through the blood stream & lymphatic system to other parts of the body. The search for anticancer agents from the plant sources alkaloids in earnest in the 1950s such as Vincristine, Vinblastine and the isolation of cytotoxic Podophyllotoxins will reduce white blood cell count and caused bone marrow depression in rats. Roots, leaves, stem, root, bark and fruity of the plant herbs are used in the treatment of cancer. The dietary antioxidants having anti carcinogenic property are in demand. Identification and characterization of these anti-carcinogens in the diet can be used for reducing the risk of human cancer. Tea (Camellia thea an evergreen plant contains antioxidants which prevent and repair cellular damage caused by reactive free radicals. Supervitamin drinks containing a combination of Hordeum vulgare, Medicago sativa and Spirulina enhances the activity of immune cells against cancer. Mentha species containing antioxidants prevent reocurrence of cancer.

    The aim of the paper is to demonstrate the application of electronic nose (e-nose) and ion mobility spectrometry (IMS) to quality control and to find out product adulteration of spice mixtures. Therefore the gaseous head space phase of four different spice mixtures (spices for sausages and saveloy) was differed from original composition and product adulteration. In this set of experiments metal-oxide type e-nose (KAMINA-type) has been used, and characteristic patterns of data corresponding to various complex odors of the four different spice mixtures were generated. Simultaneously an ion mobility spectrometer was coupled also to an emission chamber for the detection of gaseous components of spice mixtures. The two main methods that have been used show a clear discrimination between the original spice mixtures and product adulteration could be distinguished from original spice mixtures.

    The astronaut must do much work in a short time. The astronaut is exposed to much stress. For examples; Break of the hormone balance, Inappetence, Sleep shortage. Therefore the role that the meal serves as becomes big. It greatly participates in not only the health maintenance but also the mental health to consume a meal. Most of space foods are freeze dry, and the mineral is abundant, but it is necessary for the vitamins to add it particularly. When I think about it, the cultivation of the fresh vegetables with the spaceship is necessary. The Asian project team suggested cultivation of the herb in the space. The herbs were sweet basil, Dukung Abak, Hempedu Bumi and Chinese holly basil. Each herb has a fragrance ingredient. The fragrance ingredient stimulates human sense of smell. The fragrance ingredient increases an appetite. The good fragrance derives a good sleep. I can feel passage of time by observing a plant being brought up. It helps mental health to bring up a plant. We try that we bring up herb under a condition of the space. Because an experiment on the ground was over, we report it. The sweet basil which a germination rate has good is the first candidate when we think about temperature and light quantity in the space. Three kinds of other herbs are slow-growing and germination-rate is lower than sweet basil. We think that probably we will send a sweet basil to the spaceship in space. After a sweet basil grew up in a spaceship, we analyze a fragrance ingredient. We will cook the sweeter basil and want to eat.

    Full Text Available Increasing and inadvertent use of herbs makes herb-drug interactions a focus of research. Concomitant use of warfarin, a highly efficacious oral anticoagulant, and herbs causes major safety concerns due to the narrow therapeutic window of warfarin. This paper presents an update overview of clinical findings regarding herb-warfarin interaction, highlighting clinical outcomes, severity of documented interactions, and quality of clinical evidence. Among thirty-eight herbs, Cannabis, Chamomile, Cranberry, Garlic, Ginkgo, Grapefruit, Lycium, Red clover, and St. John’s wort were evaluated to have major severity interaction with warfarin. Herbs were also classified on account of the likelihood of their supporting evidences for interaction. Four herbs were considered as highly probable to interact with warfarin (level I, three were estimated as probable (level II, and ten and twenty-one were possible (level III and doubtful (level IV, respectively. The general mechanism of herb-warfarin interaction almost remains unknown, yet several pharmacokinetic and pharmacodynamic factors were estimated to influence the effectiveness of warfarin. Based on limited literature and information reported, we identified corresponding mechanisms of interactions for a small amount of “interacting herbs.” In summary, herb-warfarin interaction, especially the clinical effects of herbs on warfarin therapy should be further investigated through multicenter studies with larger sample sizes.

    After nearly a decade of concern over the role of food and beverage marketing to youth in the childhood obesity epidemic, American children and adolescents - especially those from communities of color - are still immersed in advertising and marketing environments that primarily promote unhealthy foods and beverages. Despite some positive steps, the evidence shows that the food and beverage industry self-regulation alone is not likely to significantly reduce marketing of unhealthy foods and beverages to youth. A variety of research is needed to monitor industry marketing of unhealthy products to young people, and identify the most promising approaches to improve children's food marketing environments. The continued presence of unhealthy marketing toward children despite years of industry self-regulation suggests it is time for stronger action by policymakers to protect young people from harmful marketing practices.

    Spices can present high microbial counts and Clostridium perfringens, Bacillus cereus, Salmonella and Shigella, among others have been isolated from spices. C. perfringens is an important pathogen agent causing, among other diseases, enteritis in humans caused by C. perfringens enterotoxin (CPE) which causes human food poisoning and enterotoxemia in domestic animals. The aims of the present work were (i) to establish the hygienic sanitary quality of some spices in San Luis, Argentina; (ii) to determine the presence of C. perfringens in these spices by means of the most probable number (MPN) and count on plate methods; (iii) to characterize the enterotoxigenic strains of C. perfringens by PCR and immunological methods such as reverse passive latex agglutination (RPLA) and (iv) to type by PCR C. perfringens strains isolated. A total of 115 samples of spices, 67 of which were purchased in local retail stores and 48 domestically collected were analysed. Total aerobe counts on tryptone glucose yeast extract agar medium of the 115 samples were between <10 and 10(6) CFU/g. The colifecal counts using Mac Conkey broth of the 115 samples were <4-10(3)CFU/g, with 28 samples (24.34%) exceeding the limit established by the Spanish Alimentary Code (10 CFU/g) while 2 samples (1.73%) had a sulfite reducing anaerobe load above standard limits. A total of 14 C. perfringens strains (12.17%) were isolated and characterized from 115 samples by the standard biochemical tests. Four of which (28.60%) turned out to be enterotoxigenic by PCR and RPLA. In order to type C. perfringens strains based on their main toxins, the 14 strains were analysed by PCR. All strains belonged to type A. All RPLA positive strains were cpe(+) by PCR. The percentage of enterotoxigenic strains was more elevated that those reported in other studies for this type of sample. These results indicate that sanitary conditions in different production stages of species must be improved to reduce health hazards. The high

    Full Text Available Abstract Background A latent behavior of a biological cell is complex. Deriving the underlying simplicity, or the fundamental rules governing this behavior has been the Holy Grail of systems biology. Data-driven prediction of the system components and their component interplays that are responsible for the target system’s phenotype is a key and challenging step in this endeavor. Results The proposed approach, which we call System Phenotype-related Interplaying Components Enumerator (Spice, iteratively enumerates statistically significant system components that are hypothesized (1 to play an important role in defining the specificity of the target system’s phenotype(s; (2 to exhibit a functionally coherent behavior, namely, act in a coordinated manner to perform the phenotype-specific function; and (3 to improve the predictive skill of the system’s phenotype(s when used collectively in the ensemble of predictive models. Spice can be applied to both instance-based data and network-based data. When validated, Spice effectively identified system components related to three target phenotypes: biohydrogen production, motility, and cancer. Manual results curation agreed with the known phenotype-related system components reported in literature. Additionally, using the identified system components as discriminatory features improved the prediction accuracy by 10% on the phenotype-classification task when compared to a number of state-of-the-art methods applied to eight benchmark microarray data sets. Conclusion We formulate a problem—enumeration of phenotype-determining system component interplays—and propose an effective methodology (Spice to address this problem. Spice improved identification of cancer-related groups of genes from various microarray data sets and detected groups of genes associated with microbial biohydrogen production and motility, many of which were reported in literature. Spice also improved the predictive skill of the

  3. A review on spices. Present status of decontamination techniques such as gamma irradiation

    International Nuclear Information System (INIS)

    The problem of flavour-preserving conservation of spices is described and discussed with a view to their use in the food industry. A number of possible ways of spice and spice extract conservation are presented. The main problem in spice conservation is the removal of contaminating microorganisms without loss or adulteration of taste. The number of microorganisms in spices is about 103 to 108 per g spice. Among these are soil microorganisms such as aerobic spoilage organisms, spore-formers, proteolytic and gas-producing bacteria. The incorporation of 0.1-1% spices into meat products may lead to a contamination of 105 to 106 organisms/g product. Extracted spice oils, on the other hand, are free of microorganisms. A number of physical and chemical sterilisation techniques are proposed. Radiosterilisation, in particular by means of gamma rays, is dealt with in detail. Here, a dose of 0.33 to 1.5 Mrad will kill the vegetative microorganisms, and complete sterilisation is achieved at 1.5 to 2.5 Mrad. Combination with heat or chemicals may bring about a 20% reduction in the amount of ionizing radiation required. There were no quality losses in the spices. Legalisation of ionizing radiation for spice conservation will require further tests of safety to be carried out. (AJ)

    The objective of this article is to provide a review of the fundamental aspects of body fluid balance and the physiological consequences of water imbalances, as well as discuss considerations for the optimal composition of a fluid replacement beverage across a broad range of applications. Early pioneering research involving fluid replacement in persons suffering from diarrheal disease and in military, occupational, and athlete populations incurring exercise- and/or heat-induced sweat losses has provided much of the insight regarding basic principles on beverage palatability, voluntary fluid intake, fluid absorption, and fluid retention. We review this work and also discuss more recent advances in the understanding of fluid replacement as it applies to various populations (military, athletes, occupational, men, women, children, and older adults) and situations (pathophysiological factors, spaceflight, bed rest, long plane flights, heat stress, altitude/cold exposure, and recreational exercise). We discuss how beverage carbohydrate and electrolytes impact fluid replacement. We also discuss nutrients and compounds that are often included in fluid-replacement beverages to augment physiological functions unrelated to hydration, such as the provision of energy. The optimal composition of a fluid-replacement beverage depends upon the source of the fluid loss, whether from sweat, urine, respiration, or diarrhea/vomiting. It is also apparent that the optimal fluid-replacement beverage is one that is customized according to specific physiological needs, environmental conditions, desired benefits, and individual characteristics and taste preferences.

    Full Text Available Abstract Conventional drugs treat diabetes by improving insulin sensitivity, increasing insulin production and/or decreasing the amount of glucose in blood. Several herbal preparations are used to treat diabetes, but their reported hypoglycemic effects are complex or even paradoxical in some cases. This article reviews recent findings about some of the most popular hypoglycemic herbs, such as ginseng, bitter melon and Coptis chinensis. Several popular commercially available herbal preparations are also discussed, including ADHF (anti-diabetes herbal formulation, Jiangtangkeli, YGD (Yerbe Mate-Guarana-Damiana and BN (Byakko-ka-ninjin-to. The efficacy of hypoglycemic herbs is achieved by increasing insulin secretion, enhancing glucose uptake by adipose and muscle tissues, inhibiting glucose absorption from intestine and inhibiting glucose production from heptocytes.

    The growing number of Alzheimer's disease (AD) patients prompted us to seek effective natural resources for the prevention of AD. We focused on the inhibition of β-secretase, which is known to catalyze the production of senile plaque. Sixteen spices used in Asian countries were selected for the screening. Among the extracts tested, hexane extracts obtained from turmeric, cardamom, long pepper, cinnamon, Sichuan pepper, betel, white turmeric and aromatic ginger showed potent inhibitory activities. Their active principles were identified as sesquiterpenoids, monoterpenoids, fatty acid derivatives and phenylpropanoids using GC-MS analyses. The chemical structures and IC50 values of the compounds are disclosed. The results suggest that long-term consumption'of aromatic compounds from spices could be effective in the prevention of AD.

    The bacterial counts of commercially available species were found to be in the range of 10/sup 2/-10/sup 7//g, whereas the fungal counts varied between 10/sup 2/ and 10/sup 3//g. Among the five spices studied, pepper, cardamom, and nutmeg mace had a high microbial load compared to cinnamon and clove. Exposure to ..gamma..-irradiation in the dose range of 7.5-10 kGy was adequate to sterilize all the spices. The essential oil of clove and cinnamon exhibited inhibitory properties against aflatoxin-producing aspergilli. ..gamma..-Irradiation did not affect fungal inhibitory principles present in clove, though marginal reduction was observed in that of cinnamon.

    2007-11-01

    An equivalent circuit model of nanowire diodes is introduced. Because nanowire diodes inevitably involve a metal-semiconductor-metal structure, they consist of two metal-semiconductor contacts and one resistor in between these contacts. Our equivalent circuit consists of two Schottky diodes and one resistor. The current through the reverse-biased Schottky diode is calculated from the thermionic field emission (TFE) theory and that of the forward-biased Schottky diode is obtained from the classical thermionic emission (TE) equation. Our model is integrated into the conventional circuit simulator SPICE by a sub-circuit with TFE and TE routines. The results simulated with our model by SPICE are in good agreement with various, previously reported experimental results. PMID:18047126

    2012-07-01

    The increasing use of myristicin (a component of nutmeg) as a cheap hallucinogenic intoxicant requires from the world of science the elaboration of new methods for determination of this compound in daily-use foodstuffs. The present study describes a fast, simple and sensitive method of myristicin analysis in nutmeg and spices containing it using gas chromatography combined with ultrasonic solvent extraction and solid phase extraction processes. The developed method is characterized by high recovery (almost 100%), a low detection limit 1.35 ng g(-1) and good repeatability (average RDS value equal 2.39%). The presented analytical approach constitutes a substantial improvement on previously reported methods for myristicin analysis and seems to be the method of choice for determining the amount of the compound in spices containing nutmeg.

    2006-01-01

    An accurate photodiode circuit macro-model is proposed for SPICE simulation. The definition and implementation of the macro-model is based on carrier stationary continuity equation. In this macro-model, the photodiode is a device of three pins, one for light intensity input and the other two for photocurrent output, which represent the relationship between photocurrent and incident light. The validity of the proposed macro-model is demonstrated with its PSPICE simulation result compared with reported experimental data.

    A SPICE module for the Satellite Orbit Analysis Program (SOAP) precisely represents complex motion and maneuvers in an interactive, 3D animated environment with support for user-defined quantitative outputs. (SPICE stands for Spacecraft, Planet, Instrument, Camera-matrix, and Events). This module enables the SOAP software to exploit NASA mission ephemeris represented in the JPL Ancillary Information Facility (NAIF) SPICE formats. Ephemeris types supported include position, velocity, and orientation for spacecraft and planetary bodies including the Sun, planets, natural satellites, comets, and asteroids. Entire missions can now be imported into SOAP for 3D visualization, playback, and analysis. The SOAP analysis and display features can now leverage detailed mission files to offer the analyst both a numerically correct and aesthetically pleasing combination of results that can be varied to study many hypothetical scenarios. The software provides a modeling and simulation environment that can encompass a broad variety of problems using orbital prediction. For example, ground coverage analysis, communications analysis, power and thermal analysis, and 3D visualization that provide the user with insight into complex geometric relations are included. The SOAP SPICE module allows distributed science and engineering teams to share common mission models of known pedigree, which greatly reduces duplication of effort and the potential for error. The use of the software spans all phases of the space system lifecycle, from the study of future concepts to operations and anomaly analysis. It allows SOAP software to correctly position and orient all of the principal bodies of the Solar System within a single simulation session along with multiple spacecraft trajectories and the orientation of mission payloads. In addition to the 3D visualization, the user can define numeric variables and x-y plots to quantitatively assess metrics of interest.

    SPICE is a high resolution imaging spectrometer operating at extreme ultraviolet wavelengths, 70.4 - 79.0 nm and 97.3 - 104.9 nm. It is a facility instrument on the Solar Orbiter mission. SPICE will address the key science goals of Solar Orbiter by providing the quantitative knowledge of the physical state and composition of the plasmas in the solar atmosphere, in particular investigating the source regions of outflows and ejection processes which link the solar surface and corona to the heliosphere. By observing the intensities of selected spectral lines and line profiles, SPICE will derive temperature, density, flow and composition information for the plasmas in the temperature range from 10,000 K to 10MK. The instrument optics consists of a single-mirror telescope (off-axis paraboloid operating at near-normal incidence), feeding an imaging spectrometer. The spectrometer is also using just one optical element, a Toroidal Variable Line Space grating, which images the entrance slit from the telescope focal plane onto a pair of detector arrays, with a magnification of approximately x5. Each detector consists of a photocathode coated microchannel plate image intensifier, coupled to active-pixel-sensor (APS). Particular features of the instrument needed due to proximity to the Sun include: use of dichroic coating on the mirror to transmit and reject the majority of the solar spectrum, particle-deflector to protect the optics from the solar wind, and use of data compression due to telemetry limitations.

    Extensive research within the last half a century has revealed that cancer is caused by dysregulation of as many as 500 different gene products. Most natural products target multiple gene products and thus are ideally suited for prevention and treatment of various chronic diseases, including cancer. Dietary agents such as spices have been used extensively in the Eastern world for a variety of ailments for millennia, and five centuries ago they took a golden journey to the Western world. Various spice-derived nutraceuticals, including 1'-acetoxychavicol acetate, anethole, capsaicin, cardamonin, curcumin, dibenzoylmethane, diosgenin, eugenol, gambogic acid, gingerol, thymoquinone, ursolic acid, xanthohumol, and zerumbone derived from galangal, anise, red chili, black cardamom, turmeric, licorice, fenugreek, clove, kokum, ginger, black cumin, rosemary, hop, and pinecone ginger, respectively, are the focus of this review. The modulation of various transcription factors, growth factors, protein kinases, and inflammatory mediators by these spice-derived nutraceuticals are described. The anticancer potential through the modulation of various targets is also the subject of this review. Although they have always been used to improve taste and color and as a preservative, they are now also used for prevention and treatment of a wide variety of chronic inflammatory diseases, including cancer.

Maton, Zingiberaceae), ginger ((Zingiber officinale Rosc., Zingiberaceae), and saffron (Crocus sativus L., Iridaceae) have been investigated at room temperature. All unirradiated spices presented a weak resonance line with g-factors around free-electron ones. After γ-ray irradiation at an absorbed dose of up to 11.3 kGy, the presence of EPR spectra whose amplitude increase monotonously with the absorbed dose has been noticed with all spices. A 100 oC isothermal annealing of 11.3 kGy irradiated samples has shown a differential reduction of amplitude of various components that compose initial spectra, but even after 3.6 h of thermal treatment, the remaining amplitude represents no less then 30% of the initial ones. The same peculiarities have been noticed after 83 days storage at room temperature but after 340 days storage at ambient conditions only irradiated ginger displays a weak signal that differs from those of unirradiated sample.

    The 9.50 GHz electron paramagnetic resonance (EPR) spectra of unirradiated and 60Co γ-ray irradiated cardamom ( Elettaria cardamomum L. Maton, Zingiberaceae), ginger (( Zingiber officinale Rosc., Zingiberaceae), and saffron ( Crocus sativus L., Iridaceae) have been investigated at room temperature. All unirradiated spices presented a weak resonance line with g-factors around free-electron ones. After γ-ray irradiation at an absorbed dose of up to 11.3 kGy, the presence of EPR spectra whose amplitude increase monotonously with the absorbed dose has been noticed with all spices. A 100 °C isothermal annealing of 11.3 kGy irradiated samples has shown a differential reduction of amplitude of various components that compose initial spectra, but even after 3.6 h of thermal treatment, the remaining amplitude represents no less then 30% of the initial ones. The same peculiarities have been noticed after 83 days storage at room temperature but after 340 days storage at ambient conditions only irradiated ginger displays a weak signal that differs from those of unirradiated sample. All these factors could be taken into account in establishing at which extent the EPR is suitable to evidence any irradiation treatment applied to these spices.

    Extensive research within the last half a century has revealed that cancer is caused by dysregulation of as many as 500 different gene products. Most natural products target multiple gene products and thus are ideally suited for prevention and treatment of various chronic diseases, including cancer. Dietary agents such as spices have been used extensively in the Eastern world for a variety of ailments for millennia, and five centuries ago they took a golden journey to the Western world. Various spice-derived nutraceuticals, including 1′-acetoxychavicol acetate, anethole, capsaicin, car-damonin, curcumin, dibenzoylmethane, diosgenin, eugenol, gambogic acid, gingerol, thymoquinone, ursolic acid, xanthohumol, and zerumbone derived from galangal, anise, red chili, black cardamom, turmeric, licorice, fenugreek, clove, kokum, ginger, black cumin, rosemary, hop, and pinecone ginger, respectively, are the focus of this review. The modulation of various transcription factors, growth factors, protein kinases, and inflammatory mediators by these spice-derived nutraceuticals are described. The anticancer potential through the modulation of various targets is also the subject of this review. Although they have always been used to improve taste and color and as a preservative, they are now also used for prevention and treatment of a wide variety of chronic inflammatory diseases, including cancer.

    Full Text Available A powerful time-domain FDTD-SPICE simulator is implemented and applied to the broadband analysis of metamaterials integrated with active and tunable circuit elements. First, the FDTD-SPICE modeling theory is studied and details of interprocess communication and hybridization of the two techniques are discussed. To verify the model, some simple cases are simulated with results in both time domain and frequency domain. Then, simulation of a metamaterial structure constructed from periodic resonant loops integrated with lumped capacitor elements is studied, which demonstrates tuning resonance frequency of medium by changing the capacitance of the integrated elements. To increase the bandwidth of the metamaterial, non-Foster transistor configurations are integrated with the loops and FDTD-SPICE is applied to successfully bridge the physics of electromagnetic and circuit topologies and to model the whole composite structure. Our model is also applied to the design and simulation of a metasurface integrated with nonlinear varactors featuring tunable reflection phase characteristic.

The ethanol extract of Sichuan pepper showed the highest ability of DPPH radical scavenging. The extract with the highest ABTS radical scavenging effect was that of ethanol extract of cinnamon. Both ethanol and water extracts of cinnamon possessed the high ferric reducing antioxidant power (FRAP) with the values of 4 541.87 and 1 134.52 µmol of Fe (Ⅱ)/g. The extracts with high hydroxyl radical-mediated deoxyribose degradation were all the ethanol extracts as follows:cinnamon, bay leaf, Sichuan pepper, star anise and fennel. The extracts with high antioxidant activities also had the high contents of the phenols. The study indicated that these spices might be potentially be used as natural antioxidants in food.

  6. EPR investigation of some irradiated traditional oriental spices

    International Nuclear Information System (INIS)

    The X-band EPR spectra of unirradiated and 60 Co gamma ray irradiated cardamom (Elettaria cardamomum L. Maton, Zingiberaceae), ginger ((Zingiber officinale Rosc., Zingiberaceae), saffron (Crocus sativus L., Iridaceae), and curry have been investigated at room temperature. All unirradiated spices presented a weak resonance line with g-factors around free-electron ones, most probably due to the presence of semiquinones, previously reported to have paramagnetic properties. After gamma ray irradiation at absorbed dose up to 11.3 kGy we have noticed in all spices the presence of complex EPR spectra consisting of a superposition of at last two different paramagnetic species whose amplitude increase monotonously with the absorbed dose. A 100 deg. C isothermal annealing of 11.3 kGy irradiated samples has shown a differential reduction of amplitude of various components that form the initial spectra, but even after 5 h of thermal treatment, the remaining amplitude represents no less than 40% from the initial ones, testifying for a good thermal stability. The presences of initial EPR spectra as well as the remaining amplitude after isothermal annealing are very useful in identifying any irradiation treatment applied to this category of species.

    Clove (Syzygium aromaticum) is one of the most valuable spices that has been used for centuries as food preservative and for many medicinal purposes. Clove is native of Indonesia but nowadays is cultured in several parts of the world including Brazil in the state of Bahia. This plant represents one of the richest source of phenolic compounds such as eugenol, eugenol acetate and gallic acid and posses great potential for pharmaceutical, cosmetic, food and agricultural applications. This review includes the main studies reporting the biological activities of clove and eugenol. The antioxidant and antimicrobial activity of clove is higher than many fruits, vegetables and other spices and should deserve special attention. A new application of clove as larvicidal agent is an interesting strategy to combat dengue which is a serious health problem in Brazil and other tropical countries. Pharmacokinetics and toxicological studies were also mentioned. The different studies reviewed in this work confirm the traditional use of clove as food preservative and medicinal plant standing out the importance of this plant for different applications.

    The basic equivalent circuit of a p-n junction solar cell is most commonly represented as consisting of a current source in parallel with two diodes and two parasitic resistances. The output of a solar cell is measured by obtaining the current-voltage (I-V) characteristics for different illumination intensities, and various parameters are extracted from these characteristics. Because the nature of the information derived from these characteristics is not obvious to the beginning students in photovoltaics, a simulation using SPICE was utilized to explain three solar cell I-V characteristics—dark I-V, illuminated I-V, and open circuit voltage versus the short circuit current (illumination intensity). Students can construct a solar cell and study the effect of the diode and parasitic parameters on the three output I-V characteristics. Series and parallel combinations of solar cells for arrays and modules using bypass diodes are demonstrated using SPICE as educational tools for understanding the role of bypass diodes.

  9. Radiosterilization or sterilization by steam. Procedures for sterilization of spices

    International Nuclear Information System (INIS)

    The article compares two different methods for the sterilization of spices, namely radiosterilization and sterilization with steam. The first method applies ionizing radiation which can alter the chemical composition of the products. Tests have shown, however, that radiation doses up to 10 kGy will not induce the formation of carcinogenic agents in the foodstuffs, or of toxic substances, and thus are a wholesome method of preservation. Any modifications of taste, color or smell, or loss of vitamins, can be avoided by proper dose control and standard irradiation conditions. Sterilization by steam is a method achieving substantial suppression of the formation of germs, aerobic spores, yeasts, mould, and gramnegative germs, while preserving in most cases the essential oils. It may result in sensoric alterations, i.e affect the color, smell or taste, but in general the spices thus treated preserved their characteristic properties. The method is a good alternative to radiosterilization. The article adds some concluding information on mandatory labelling of irradiated food imported from third countries

    This study provides a qualitative comparison of blackcurrant and blackcurrant-whey beverages over a 12-month storage period. The amount of extract in the beverages was established as 12%, of which 25% was blackcurrant concentrate. Acid whey was used for the production of blackcurrant-whey beverages. In comparison to blackcurrant-whey beverages, blackcurrant beverages contained significantly more glucose, fructose, sucrose, polyphenols and vitamins C and B1. They also had a higher level of antioxidant activity against ABTS•+ and DPPH, with the difference ranging from 2% to 46%. On the other hand, blackcurrant-whey beverages contained more ash, proteins and vitamin B2 and the presence of lactose was detected. They were also characterized by higher color parameter values evaluated according to the CIE system. A general sensory evaluation awarded blackcurrant beverages with 0.5-1.3 more points than blackcurrant-whey beverages. A descriptive flavor analysis found that blackcurrant taste dominated in both types of beverages; however, in blackcurrant-whey beverages, the taste and smell of whey were also discernible. Changes in the quality of the beverages were observed during the storage period, notably a decrease in their antioxidant properties. PMID:21844063

    Full Text Available Herbs of Origanum genus are rich in essential oils and contain large amounts of phenols, lipids, fatty acids, flavonoids and anthocyanins. Antioxidant activity of these herbs depends on many factors, including the type herbs, post-harvest processing and subsequent processing. The aim of this study was therefore to confirm the hypothesis that the composition of oils of these two herbs of the Origanum genus depends on the post-harvest treatment of herbs and that the dried herb antioxidant activity is higher for fresh than that of frozen herbs. Lamiaceae family herbs: oregano (Origanum vulgare L. and Greek oregano (Origanum heracleoticum L. were planted and analyzed. Herb samples were extracted by hot demineralised water. DPPH (2,2-diphenyl-1-picrylhydrazyl radical scavenging method was used for antioxidant activity assessment. The total phenolic content was determined spectrophotometrically by using Folin-Ciocalteu reagent. Steam distillation of essential oils was carried out via Clevenger Apparatus. The obtained essential oils were analysed by GC-MS technique. Results of tested fresh, dried and frozen herbs showed a considerable potential for quenching the free DPPH radical. Significantly higher antioxidant activity was found in dried herbs comparing to fresh and frozen, but only in case of values calculated per 100 g of the sample. However, the differences were not statistically significant after recalculation when expressed on dry matter content. There was no difference between fresh and frozen samples. The content of total phenols was significantly higher in dried than in frozen herbs in values recalculated per 100 g of sample. A strong correlation between the results of DPPH and TPC was found again only for values expressed per 100 g of the sample. Post-harvest treatment of herbs affects the composition of their essential oils. The dominant essential oil component of Greek oregano is carvacrol with a proportion of 60% or more. On the contrary

    Full Text Available Herbal coffee is one of the coffee diversivication product that has been well recognized in the market. The addition of herbs or spices, such as ginger, pasak bumi (Eurycoma longifolia, Panax (from the genus of Panax L. and Habbatussauda (black cumin/black seed/Nigella sativa in the coffee, not only offer an enhanced flavor characteristic, but more importantly also offer the consumer to gain a health benefit which are possessed by the herbs used. Cardamom (Amonum cardomum is commonly recognized as a food spices to add flavor to dishes. Cardamom is also known as a herb that possess health benefit such as the medicine for tonsil and throat inflammation, fever, asthma and fatigue reliever. This research was aimed to develop a herbal coffee containing the extract of cardamom and to study the characteristic of herbal coffee obtained physicochemically and by sensory analysis. Crystallized coffee and sugar mixture was blended with cardamom extract by several ratio, which were 90%:10%, 80%:20%, 70%:30%, 60%:40% and 50%:50% to obtain ready to drink cardamom herbal coffee. The mixtures and control (without the addition of cardamom were then subjected for consumer perception by testing it to 30 panelist based on hedonic sensory test. The 3 mixtures that were choosen were then analysed for its physicochemical characteristic such as its powder and brewing appearrance, insoluble solids, reducing sugar and caffein concentration. The result showed that the addition of 10%, 20% and 30% cardamom extracthad good preferences to consumer, which 10% of addition resulted the highest preferences. The hedonic sensory test resulted the preferences of the aforementioned herbal coffee on color, aroma, taste and flavor was 3.37; 3.14; 3.30; 3.27 and 3.37 (on scale 1 to 5, respectively, representing moderately like to like preferences.The physiscochemical analysis show that the mixture contain 0.17% of insoluble solid, 0.13% of reducing sugar and 0.45% caffeine which comply

  17. Viscosity measurement - probably a means for detecting radiation treatment of spices?

    International Nuclear Information System (INIS)

    The viscosity of 13 different spices and dried vegetables in total was measured. Optimal conditions were first determined for each product, i.e. concentration, pH-value, temperature, particle size and soaking time. For method evaluation, examinations were primarily performed to study the effect of storage, the reproducibility and the influence of the different varieties of the same spice. In supplement, for pepper, the viscosity was measured as a function of radiation dose. In summation, significant changes in the gel forming capability after irradiation could be observed after preliminary experiments in 8 dried spices (ginger, carrots, leek, cloves, pepper, celery, cinnamon and onions). With 3 spices (ginger, pepper and cinnamon) could the results from examining all different varieties of the same spice be substantiated. An additional influence of storage time on viscosity could not be proved during the investigative period of 8 months. Generally seen, there is no possibility of being able to identify an irradiated spice on the basis of viscosity measurements alone, since the difference between the varieties of one and the same spice is considerably great. However, radiation treatment can be reliably excluded with ginger, pepper and cinnamon, if the viscosities are high (10-20 Pa x s). (orig./MG)

  18. Effect of gamma irradiation on essential oils and lipids in spices

    International Nuclear Information System (INIS)

    Seven kinds of spices were irradiated with gamma-rays at the dose of 5 to 80 kGy. Studies of radiation effect on lipids in each spice were carried out by measuring peroxide value (POV), iodine value (IV), acid value (AV) and analysis of gas-chromatography (GC). POV in each spice was gradually increased with increasing absorbed doses. The increase of POV in nutmeg was higher than those of other spices, and it was suggested that those increase of POV values were related to lipid contents in spices. A little increase of IV and AV were also observed as same amount of POV by the irradiation up to 80 kGy. From the GC analysis of lipids in each spice, components were not changed even irradiated up to 50 kGy of gamma-rays. Radiation effect on components of essential oils in each spice were also analyzed by headspace-GC (HS-GC), and any degradation of components were not observed up to 50 kGy of irradiation even analyzed by GC after separation to hydrocarbon and oxygen compounds. On the contrary, essential oils of cloves sterilized by heat treatment were apparently decreased as compared with irradiated and non-irradiated cloves. (author)

    Nowadays, in developed countries the irradiation technology is a process used in food treatments for sterilization and diminishing of the microbiological charge, as well as to extend the storage life. In Mexico, the food irradiation, spices and seasonings has been officially approved since 1995, recognizing as an adequate technological process for foods. Taking advantage of knowledge about solids and due to the natural growth of the spices, herbs, etc. these contain minerals which can providing important information of its radiological history, moreover these type of materials do not degrade them preserving by long time periods. In this work, a methodology for the extraction of poly minerals in foods, such as oregano, guajillo chili, jamaica, arnica and camomile is presented. For obtaining the poly mineral, the samples were treated with an ethanol-water solution, in constant stirring during 12 hours at room temperature depending on the sample under treatment. It was used oxygenated water and distilled for washing and acetone for achieving a good drying. The minerals were processed by gamma radiation in the Nuclear Sciences Institute of the UNAM. The brilliance curves of spices and herbs, using a Tl reader of Harshaw 3500 were obtained, the emissions are located between 60 and 350 Centigrade. Previously the extraction of poly mineral was realized and they were divided in same parts for doses between 2 and 10 KGy, this last value according to the Mexican Official Standard considering a fraction without irradiating as reference. The identification of the mineral fraction by diffraction will complement the composition information. We are grateful to the donation of seasonings samples provided by the Tres Villas Natural Seasonings enterprise, Toluca plant, State of Mexico and the Academic Exchange Office at UNAM. (Author)

    This study reports that Corsican blue tit ( Parus caeruleus ogliastrae) nests contain between one to five aromatic herb species between the onset of egg laying till the chicks' finished growth 13 d after hatching. An herb removal experiment during the chick stage shows that blue tits bring fresh aromatic material 1-5 d after herb removal. Nests with a series of distinct odour classes easily perceived by humans have never been reported in birds. A new 'Potpourri' hypothesis is proposed that may explain the functional significance of this behaviour.

    Full Text Available One among several equally important subsystems of a standalone photovoltaic (PV system is the circuit for maximum power point tracking (MPPT. There are several algorithms that may be used for it. In this paper we choose such an algorithm based on the maximum simplicity criteria. Then we make some small modifications to it in order to make it more robust. We synthesize a circuit built out of elements from the list of elements recognized by SPICE. The inputs are the voltage and the current at the PV panel to DC-DC converter interface. Its task is to generate a pulse width modulated pulse train whose duty ratio is defined to keep the input impedance of the DC-DC converter at the optimal value.

    1999-12-01

    According to the application requirements for high resolution rather than high throughput, a long processing time is widely used in energy-dispersive X-ray spectrometers for detecting low-energy events. IN such cases, the major noise component that limits the spectral resolution is 1/f noise, and so the 1/f noise index of the filter should be considered. The authors describe a technique, simpler than earlier ones, for using SPICE in the computation of the 1/f, step, and delta noise indices of linear and time-valiant filters. The method is based on obtaining a weighting function from the results of simulation and is demonstrated for triangular and trapezoidal shapers. The results are compared with those obtained by direct calculation. The greatest discrepancies occur when the method is applied to gated integrators, but the errors are probably due to artifacts not related to the basic method described here.

    Culinary practices are influenced by climate, culture, history and geography. Molecular composition of recipes in a cuisine reveals patterns in food preferences. Indian cuisine encompasses a number of diverse sub-cuisines separated by geographies, climates and cultures. Its culinary system has a long history of health-centric dietary practices focused on disease prevention and promotion of health. We study food pairing in recipes of Indian cuisine to show that, in contrast to positive food pairing reported in some Western cuisines, Indian cuisine has a strong signature of negative food pairing; more the extent of flavor sharing between any two ingredients, lesser their co-occurrence. This feature is independent of recipe size and is not explained by ingredient category-based recipe constitution alone. Ingredient frequency emerged as the dominant factor specifying the characteristic flavor sharing pattern of the cuisine. Spices, individually and as a category, form the basis of ingredient composition in Indian...

    Spices and aromatic herbs are divided into leaves, flowers, bud, seeds bark or dry roots from different plants and it is possible to define them as products of highly flavored vegetal origin that volatize easily when incorporated in small quantities to food products and contribute to its aroma, flavor, color or even to its preservation. Nowadays, people look for its functional properties, bioactive compounds and sensory qualities. A big problem is the reduction of the quantity of these compounds throughout the production chain from the harvest process, storage and distribution. For a long time researchers and industries have concentrated on perfecting the processes of the production chain seeking to guarantee the sanitary and food safety, preserving foodstuffs for a long period and an increase in its lifespan without drastically altering its properties. Due to homemade products and the lack of compliance with good practices in its production chain, the spices can contain a high amount of microbiology causing serious complications to the health of the consumer and the radiation processing is often used for reduce these problems. With this finding, the objectives of this work were: Analyze the oil antifungal properties of spices irradiated with average doses (2.5; 5; 7.5 and 10 kGy); Study the average doses (5 and 10 kGy) and high dose (20 and 30 kGy) effects of gamma radiation {sup 60}Co in the bioactive compounds of the spices - cloves, cinnamon and nutmeg; Identify the oils compounds; Identify the volatile compounds in the headspace of the oils and the in natura spices.

    Concern over childhood obesity has generated a decade-long reformation of school nutrition policies. Food is available in school in 3 venues: federally sponsored school meal programs; items sold in competition to school meals, such as a la carte, vending machines, and school stores; and foods available in myriad informal settings, including packed meals and snacks, bake sales, fundraisers, sports booster sales, in-class parties, or other school celebrations. High-energy, low-nutrient beverages, in particular, contribute substantial calories, but little nutrient content, to a student's diet. In 2004, the American Academy of Pediatrics recommended that sweetened drinks be replaced in school by water, white and flavored milks, or 100% fruit and vegetable beverages. Since then, school nutrition has undergone a significant transformation. Federal, state, and local regulations and policies, along with alternative products developed by industry, have helped decrease the availability of nutrient-poor foods and beverages in school. However, regular access to foods of high energy and low quality remains a school issue, much of it attributable to students, parents, and staff. Pediatricians, aligning with experts on child nutrition, are in a position to offer a perspective promoting nutrient-rich foods within calorie guidelines to improve those foods brought into or sold in schools. A positive emphasis on nutritional value, variety, appropriate portion, and encouragement for a steady improvement in quality will be a more effective approach for improving nutrition and health than simply advocating for the elimination of added sugars.

    Full Text Available Background. Production of fermented probiotic beverages can be a good method for acid whey usage. The obtained products combine a high nutritional value of whey with health benefits claimed for probiotic bac- teria. The aim of the study was to define quality properties of beverages based on fresh acid whey and milk with addition of buttermilk powder or sweet whey powder. Material and methods. Samples were inoculated with two strains of commercial probiotic cultures: Lac- tobacillus acidophilus La-5 or Bifidobacterium animalis Bb-12. After fermentation, samples were stored at refrigerated conditions. After 1, 4, 7, 14 and 21 days sensory characteristics, hardness, acetaldehyde content, titratable acidity, pH acidity and count of bacteria cells were evaluated. Results. Throughout all storage period, the number of bacteria was higher than 8 log cfu/ml in the all sam- ples. Beverages with La-5 strain had higher hardness and acidity, whilst samples with Bb-12 contained more acetaldehyde. Samples with buttermilk powder had better sensory properties than with sweet whey powder. Conclusions. Obtained products made of acid whey combined with milk and fortified with buttermilk pow- der or sweet whey powder, are good medium for growth and survival of examined probiotic bacteria strains. The level of bacteria was sufficient to provide health benefits to consumers.

    Full Text Available Seventeen species of herbs established in Thai traditional remedies were microbially decontaminated by gamma-irradiation doses of 7.7 and 8.8 kGy. The herb samples were randomly collected four times from producers in Chiangmai during a 1-year period. These were tested, qualitatively and quantitatively, for total aerobic bacteria, Staphylococcus spp., Salmonella spp., coliform bacteria, and fungi before and after gamma treatment. No microorganisms were found after gamma treatment; and the color, aroma, and texture of the herbs remained normal. The applied dose of gamma irradiation was within the regulatory limits in Thailand (<10 kGy and the main export country (USA< 30 kGy. Gamma irradiation is an effective treatment for microbial decontamination of Thai export herbs.

    Full Text Available The cough is a protective reflex mechanism that removes foreign material and secretions from the bronchi and bronchioles of the airways; it is inappropriately stimulated in various situations like inflammation of the respiratory tract or neoplasia. In these cases, cough has a pathological character and it is necessary sometimes to use cough-suppressant drugs. The most frequently used antitussive drugs in clinical conditions produce adverse effects like depression of the respiratory centre, decreased secretion in the bronchioles and inhibition of ciliary activity, increased sputum viscosity, decreased expectoration, hypotension and constipation acts as limitation to the therapy. Use of herbal drugs is increasing all over the world for various ailments including antitussive activity as they are safe and devoid of adverse effects. Medicinal plants are an important source for the discovery of novel bioactive compounds, which have served and continue to serve as lead molecules for the development of new drugs. Thus this review may provide an insight into herbs possessing antitussive activity.

  8. Detection of irradiated spices using photo-stimulated luminescence technique (PSL)

    International Nuclear Information System (INIS)

    Photo-stimulated luminescence (PSL) technique was applied to detect irradiated black pepper (Piper nigrum), cinnamon (Cinnamomum verum) and turmeric (Curcuma longa) after dark storage for 1 day, 3 and 6 months. Using screening and calibrated PSL, all samples were correctly discriminated between non-irradiated and spices irradiated with doses 1, 5 and 10 kGy. The PSL photon counts (PCs) of irradiated spices increased with increasing dose, with turmeric showing highest sensitivity index to irradiation compared to black pepper and cinnamon. The differences in response are possibly attributed to the varying quantity and quality of silicate minerals present in each spice sample. PSL signals of all irradiated samples reduced after 3 and 6 months storage. The results of this study provide a useful database on the applicability of PSL technique for the detection of Malaysian irradiated spices

  9. Effect of gamma irradiation on essential oils and lipids in spices

    International Nuclear Information System (INIS)

    Four kinds of spices were irradiated with gamma-rays at a dose of 10 to 50 kGy. Studies on radiation effect on essential oils and lipids in spices were carried out by gas-chromatography (GC). The GC analysis of lipids in spices revealed that components were not changed even after irradiation up to 50 kGy of gamma-rays. Radiation effect on components of essential oils in spices were analyzed by headspace-GC (HS-GC) and GC after separation to hydrocarbon compounds and oxygen compounds, and any degradation of components was not observed up to 50 kGy of irradiation. On the contrary, essential oils of cloves sterilized by heat treatment were apparently decreased as compared with irradiated and non-irradiated cloves. (author)

  10. A first countercheck trial to identify irradiated spices with luminescence techniques

    International Nuclear Information System (INIS)

    The Federal Health Office, in collaboration with 4 institutions responsible for food control analysis and 2 research facilities, for the first time conducted a countercheck trial to identify irradiated spices. This test was mainly intended to find out whether chemiluminescence (CL) and thermoluminescence (TL) techniques are appropriate for this purpose. Nine different spices were selected. Approximately 85% of the samples may be identified correctly if both methods are used. However, only 3% of all spices subjected to CL analysis were falsely identified as irradiated, and the proportion of falsely positive results is even lower than 1% if only those spices are considered for which CL analysis is well suited. If an additional procedure, such as TL, is applied, it is highly probable that false identification of non-irradiated samples may be excluded. (orig./PW)

    The effect of the gamma rays treatment emitted by a source of cobalt 60 in dose of 0, 3, 6 and 10 kGy on the microbiological and psycho-chemical properties of three samples of spice (hot pepper, fennel and coriander) have been studied. This study allowed us to measure the effect of these doses of irradiation on the lengthening of the lengthen conservation during storage of eight weeks to ambient temperature. The results show that the irradiation is very effective from a microbiological stand point. In fact, starting from 10 kGy the spices was not contaminated any more. The irradiation until a dose of dose 10 kGy has not generated any significant modifications, mainly in the physico-chemical parameters of the spices. But high diminishing has ac cured in water potency. Regarding colour variation, the irradiation has permitted the creation of a brighter colour for the three spices treated. A long the follow up we have an important multiplication in all bacteria existent in the three spices. Hew ever for the spices treated in 10 kGy we did not get any recontamination. (Author)

    International Nuclear Information System (INIS)

    The efficacy of irradiation to improve the hygiene quality and to extend the storage life of commercial spices, dried fish and frozen shrimps was tested in collaboration with food industries. These tests consisted of trial irradiation of the spices used in the food industry, quality evaluation of processed meat made with irradiated spices, market testing of the irradiated dried fish and trial irradiation of commercially frozen shrimps. It was found that irradiation at 5 kGy could reduce the microbial load of the different types of spices commonly used in the food industry from 106 to 108 per gram to less than 103 per gram. The aroma and taste of certain spices became weaker or stronger after irradiation at 5 kGy, but the change was still acceptable. Use of irradiated spices in the manufacture of corned beef was found to be effective for improving the 'keeping' quality of the product stored at -2 deg. C. Market testing of the irradiated dried fish showed that the product had a longer market life and a better quality than the untreated dried fish. The microbial load of frozen shrimps could be reduced from about 105 to 106 per gram to 103 per gram when irradiated at about 5 kGy in commercial packaging. (author). 13 refs, 6 tabs

    International Nuclear Information System (INIS)

    The shelf-life of packed minced meat has been increased at least threefold at 40C by applying a 2 kGy dose. Results have been confirmed by detailed quantitative microbiological examinations. Sensory evaluations show no significant difference between the unirradiated and irradiated samples. The optimal average dose was 4 kGy for packed-frozen chicken. The number of mesophilic aerobic microbes was reduced by 2, that of psychrotolerant by 2-3 and that of Enterobacteriaceae by 3-4 orders of magnitude by 4 kGy. S. aureus and Salmonella could not be detected in the irradiated samples. in 1984-1985 5100 kg irradiated chickens were marketed labelled as radiation treated.

  12. Identification of low amount of irradiated spices (red pepper, garlic, ginger powder) with luminescence analysis

    International Nuclear Information System (INIS)

    For the identification of irradiated food, current analysis methods have limitations regarding presence and stability of radiation-induced markers. In this study, different spice blends with small quantity of different irradiated (0, 1 and 10 kGy) spice powders, such as red pepper, garlic or ginger, were investigated using PSL and TL techniques. In PSL-based screening analysis, the spice blends containing 10% of irradiated materials (1 or 10 kGy) were determined as intermediate or positive. In TL results, the blends containing 1% of 1 or 10 kGy-irradiated spices showed the typical TL glow curves that could be interpreted as positive. The blends with irradiated garlic powder provided more good results where identification was possible at 0.5% mixing of irradiated sample. However, the TL ratios of all spice blends were <0.1 and only TL glow curve shape and intensity may be used to discriminate the samples having irradiated component. - Highlights: ► Sample blends with small quantities of irradiated spices were evaluated. ► The PSL was inappropriate to detect irradiated ingredient in small quantity. ► TL glow curve shape and intensity could be used as conclusive evidence of irradiation. ► TL ratios of all irradiated and nonirradiated samples were <0.1.

    Herbal therapies gained much popularity among the general public, but compared to therapies approved by official authorities, toxicological studies are frequently not available for them. Hence, there may be inherent risks and the kidneys may be especially vulnerable to toxic effects. Herbs may induce nephrotoxicity by induction of apoptosis. High oxalate contents in Star fruit (Averrhoa carambola L.) may induce acute nephropathy. Triptolide from Thunder God Vine (Triperygium wilfordii Hook) is a diterpenoid epoxide with induces reactive oxygen species and nephrotubular apoptosis. Cranberry juice is discussed as promoter of kidney stone formation (nephrolithiasis). Abuse of guaifenesin from Roughbark (Guaicum officinale L.) increases stone formation. Aristolochia acids from Aristolochia fangchi Y.C.Wu ex L.D. Chow & S.M. Hwang causes the well-known aristolochic acid nephropathy and carcinogenesis by DNA adduct formation. Carboxyatractyloside from Impila (Callilepsis laureola DC.) inhibits mitochondrial ATP synthesis. Acute allergic interstitial nephritis was diagnosed after intake of Peruvian Cat's claw (Uncaria tomentosa Willd. DC.). Whether or not Willow Bark (Salix alba L.) induces analgesic nephropathwy is a matter of discussion. Other herbal therapies are considered to affect the rennin-angiotensisn-aldosterone (RAA) system Ephedra sinica Stapf with its ingredient ephedrine. Devil's Claw (Harpagophytum procumbens DC. Ex Meisn.) and licorice (Glycyrrhiza glabra L.) may inhibit major renal transport processes needed for filtration, secretion, and absorption. Strategies to minimize nephrotoxicity include (1) quality control and standardization of herbal products, (2) research on the molecular modes of action to better understand pathophysiological mechanisms of herbal products as well as (3) clinical trials to demonstrate efficacy and safety.

    Shaoxing Bencao, wrote by WANG Jixian in South Song dynasty (1159), is a classic Chinese medicine book which aims to revise herb properties described in former literature. There are 371 items in the book evaluating herb properties recorded in books about herbs. Keeping those the thought right, correcting those he thought wrong, complementing those missed and selecting better ones from those with disputes. He revised herb properties in 50.9% of all the items. Herb properties were evaluated mainly according to record and clinical practice with emphasis on property-effect (effect and adverse effect) relationship. Logical deduction was also used to deduce herb toxicity and quality according to herb flavor, nature, tastes and their growing environment. The book described in detail the influence of processing on the herb properties and toxicity. The evaluation methods in this book are of reference value for learning about the formation of knowledge of herb properties. PMID:21569699

    Present article depicts microbiology of starter (Balma) used in traditional solid-state fermentation of alcoholic beverage (Chhang) by Bhotiya tribe of Uttarakhand. It also highlights the importance of herbs in Balma preparation and kinetics of lactic acid and ethanol fermentation under Chhang preparation using Balma. Balma contains 214 × 10(6) cfu/g yeasts, 2.54 × 10(6) cfu/g lactic acid bacteria (LAB) and 1.4 × 10(6) cfu/g other mesophilic bacteria. ITS sequence analysis revealed a rich diversity of yeast comprising of Saccharomyces cerevisiae, Saccharomycopsis fibuligera and Saccharomycopsis malanga in Balma. 16S rDNA sequence analysis revealed Lactobacillus pentosus and Pediococcus pentosaceus among LAB, while amylolytic Bacillus subtilis and B. aerophilus among other bacteria in Balma. Based on the results, it is speculated that herbs such as Inula cuspidata, Micromeria biflora, Origanum vulgare, Rubus sp. and Thymus linearis used earlier by Bhotiya in Balma preparation contribute as a source of yeasts, LAB and amylolytic bacilli. Study also demonstrates that Bhotiya tribe is rational in preparation of starter as they have circumvented the need of plants by using previous year Balma as inoculum and possibility of deficient quality of Balma due to weak colonization of phyllosphere and rhizosphere microbiota. Results suggest that simultaneous saccharification and lactic acid-ethanol fermentation take place in traditional cereal based Chhang fermentation system of Bhotiya. PMID:26843694

  1. SPICE modeling of memristors with multilevel resistance states

    International Nuclear Information System (INIS)

    With CMOS technologies approaching the scaling ceiling, novel memory technologies have thrived in recent years, among which the memristor is a rather promising candidate for future resistive memory (RRAM). Memristor's potential to store multiple bits of information as different resistance levels allows its application in multilevel cell (MCL) technology, which can significantly increase the memory capacity. However, most existing memristor models are built for binary or continuous memristance switching. In this paper, we propose the simulation program with integrated circuits emphasis (SPICE) modeling of charge-controlled and flux-controlled memristors with multilevel resistance states based on the memristance versus state map. In our model, the memristance switches abruptly between neighboring resistance states. The proposed model allows users to easily set the number of the resistance levels as parameters, and provides the predictability of resistance switching time if the input current/voltage waveform is given. The functionality of our models has been validated in HSPICE. The models can be used in multilevel RRAM modeling as well as in artificial neural network simulations

    Full Text Available Inhibition of defined molecular steps of tumourigenesis by natural non-toxic compounds may be an efficient means to tackle the population cancer burden. Extensive research has addressed the chemotherapeutic potential of curcumin (diferuloylmethane, a relatively non-toxic plant derived polyphenol. Curcumin is used for centuries in cuisine and indigenous medicine against several major human diseases. Cancer is the second leading cause of death worldwide. Disruption of a proper regulation of cell proliferation can ultimately cause cancer. Most human malignancies are driven by chromosomal translocations or other genetic alterations that directly affect the function of critical cell cycle proteins such as cyclins as well as tumor suppressors, e.g., p53. In this regard, curcumin, the yellow pigment of the spice turmeric, has been reported to have immense potentialility for being used in cancer chemotherapy because of its control over the cell growth regulatory mechanisms and for its anti-inflammatory, anti-toxic and anti-oxidative properties. Increasingly reports are showing that curcumin can induce apoptosis in a wide variety of cancer cells. The mechanisms implicated in the inhibition of tumorigenesis by curcumin are diverse and seem to involve a combination of cell signalling pathways at multiple levels. When curcumin is combined with some cytotoxic drugs or certain other diet-derived polyphenols, synergistic effects have been demonstrated. Taken together, this review seeks to summarise the unique properties of curcumin that may be exploited for successful clinical cancer prevention.

    Green tea and apple are natural products with health benefits. These healthy properties are linked closely to the antioxidant compounds, mainly phenolic compounds. These antioxidant compounds have a potential for preventing and treating cancer, cardiovascular, inflammatory and neurodegenerative diseases in humans. The aim of the present work was to design a new beverage with high antioxidant power combining extracts of green tea and apple, studying the antioxidant composition and activity, organoleptic properties (colour) and stability status during storage at different temperatures. The majority compounds identified in the beverage were flavan-3-ols, being the (-)-epigallocatechin-3-gallate which had the highest concentration. After storage, floridzine was the compound with lower decrease of concentration. The new designed beverage had a good colour, and high antioxidant activity and stability at room temperature, so that the beverage needs no refrigeration, showing potential for the development of new healthy functional beverages.

    The analysis of aflatoxins (B1, B2, G1 and G2) and ochratoxin A (OTA) was performed in processed spices marketed in Penang, Malaysia, using immunoaffinity columns and HPLC equipped with fluorescence detector (HPLC-FD). The processed powdered spices analysed include dried chilli, fennel, cumin, turmeric, black and white pepper, poppy seed, coriander, 'garam masala', and mixed spices for fish, meat and chicken curry. Two different studies were carried out. The limit of detection (LOD) was 0.01 ng g(-1) for each aflatoxin (AF) and 0.10 ng g(-1) for OTA (signal-to-noise ratio = 3:1). In the first study, 34 commercial processed spices analysed with a mean level, range and incidence of positive samples for total AF were 1.61 ng g(-1), 0.01-9.34 ng g(-1) and 85%, respectively, and for AFB1 were 1.38 ng g(-1), 0.01-7.68 ng g(-1) and 85%, respectively. The mean level, range and incidence of positive samples for OTA were 2.21 ng g(-1), 0.14-20.40 ng g(-1) and 79%, respectively. Natural co-occurrence of AF and OTA was found in 25 (74%) samples. In the second study of 24 commercial processed spices, the mean level, range and incidence of positive samples for total AF were 8.38 ng g(-1), 0.32-31.17 ng g(-1) and 88%, respectively, and for AFB1 were 7.31 ng g(-1), 0.32-28.43 ng g(-1) and 83%, respectively. Fifteen positive samples for total AF and two positive samples for OTA exceeded the permissible Malaysian limit of 5 ng g(-1). Contamination of both mycotoxins in spices may represent another route of exposure to consumers due to their frequent and prolonged consumption, as spices are common ingredients in popular dishes among Asian countries.

    Full Text Available Whey is a by product in the process of cheese production. Composition and characteristics of whey are depending on the production technology, the end product and the quality of used milk. Liquid whey consists of approximately 93% water and contains almost 50% of total solids present in the milk of which lactose is main constituent. Lactose is the main constituent of whey while proteins represent less than 1% of total solids. Minerals and vitamins are present in fewer amounts also. Production of whey based beverages started in 1970's and until today a wide range of different whey based beverages has been developed. They can be produced from native sweet or acid whey, from deproteinised whey, from native whey which was diluted with water, from whey powder or by whey fermentation. Non alcoholic whey beverages include wide range of products obtained by mixing native sweet, diluted or acid whey with different additives like tropical fruits (but also other fruits like apples, pears, strawberries or cranberries, crops and their products (mainly bran, isolates of vegetable proteins, CO2, chocolate, cocoa, vanilla extracts and other aromatizing agents. Special attention is being paid to production of fermented whey beverages with probiotic bacteria where the most important step is the choice of suitable culture of bacteria in order to produce functional beverage with high nutritional value and acceptable sensory characteristics. Non alcoholic whey beverages also include dietetic beverages, drinks with hydrolyzed lactose, milk like drinks and powder drinks. Whey is a very good raw material for production of alcoholic beverages due to the fact that the main constituent of the solid content is lactose (about 70%. Alcoholic whey beverages include drinks with small amount of alcohol (up to 1,5%, whey beer and whey wine. Whey beverages are suitable for wide range of consumers – from children to the elderly ones. They have very high nutritional value and good

    Full Text Available The composition of apple base wine was found to be suitable for conversion into vermouth. The spices extract contained more TSS, tannins, esters, volatile acid but lower titrable acid than apple base wine. To optimize and develop apple vermouth with different ethanol concentrations (12%, 15%, 18%, sugar content (4%, 8% and spices extract (2.5% and 5.0% was prepared and was evaluated. Significant differences in physico-chemical characteristics and sensory quality amongst the vermouths having different levels of alcohol, sugar and spices extract were noted. Generally, increasing ethanol content decreased titrable acidity, tannins, macroelements and colour units while micro-elements, viscosity and total esters were increased. Increased sugar level affected TSS, apparent viscosity, pH, esters, free aldehyde, total sugar, K, Cu and Mn contents. Level of spices extract (2.5 & 5.0 did not effect TSS (ºB, titrable acidity, colour, total sugar, total tannins, volatile acidity, increased mineral contents except for K, esters and aldehyde contents. Increase in alcohol content upto 15% increased the sensory score of the product. Increased quantity of spices extract, however, decreased the mean sensory quality of vermouth. However, sensory scores for 4 or 8% sugar and 2.5 or, 5.0% spices extracted were similar. A product with 15% alcohol, 4% sugar and 2.5% spices extract was preferred the most in overall sensory quality. The studies revealed that apple fruit is suitable for making vermouth by the method described. The spices, herbs, their parts and the quantities used are also reported.A composição de vinho de maçã demonstrou ser satisfatório para se convertido em vermute.

    Full Text Available Abstract Background Cronobacter spp. (formerly Enterobacter sakazakii, are a group of Gram-negative pathogens that have been implicated as causative agents of meningitis and necrotizing enterocolitis in infants. The pathogens are linked to infant formula; however, they have also been isolated from a wide range of foods and environmental samples. Results In this study, 233 samples of food, infant formula and environment were screened for the presence of Cronobacter spp. in an attempt to find its source. Twenty nine strains were isolated from samples of spices, herbs, infant foods, and dust obtained from household vacuum cleaners. Among the 76 samples of infant food, infant formula, milk powder and non-milk dairy products tested, only one sample of infant food contained Cronobacter spp. (1.4%. The other Cronobacter spp. isolates recovered include two from household vacuum dust, and 26 from 67 samples of herbs and spices. Among the food categories analyzed, herbs and spices harbored the highest number of isolates, indicating plants as a possible reservoir of this pathogen. Initial screening with API 20E test strips yielded 42 presumptive isolates. Further characterization using 3 chromogenic media (α-MUG, DFI and EsPM and 8 sets of PCR primers detecting ITS (internal transcribed spacer sequences, 16S rRNA, zpx, gluA, gluB, OmpA genes followed by nucleotide sequencing of some PCR amplicons did not confirm the identity of all the isolates as none of the methods proved to be free of both false positives or false negatives. The final confirmation step was done by 16S rRNA sequence analysis identifying only 29 of the 42 isolates as Cronobacter spp. Conclusion Our studies showed that Cronobacter spp. are highly diverse and share many phenotypic traits with other Enterobacteriaceae members highlighting the need to use several methods to confirm the identity of this pathogen. None of the biochemical, chromogenic or PCR primers proved to be a reliable

    Spices and lactic acid bacteria have natural antimicrobial substances and organic compounds having antagonistic activity against microorganisms. The objective of this study was to investigate the role of spices and lactic acid bacteria as antimicrobial agent to extend the shelf life of metata ayib. Antimicrobial activities of spices and lactic acid bacteria (LAB) filtrates were determined by agar well diffusion method against E. coli, S. aureus, S. flexneri and S. peumoniae. Aantimicrobial activity of garlic was found to be the most effective against all the tested pathogens. Inhibition zones of garlic extract against all pathogens was significantly (P ≤ 0.05) greater than the remaining spice extracts. Inhibition zones (12.50 ± 1.00 to 15.50 ± 1.00 mm) of ginger and R. graveolens ethanol extracts against all tested pathogens were significantly (P ≤ 0.05) greater than the remaining solvent extracts. Inhibition zone of O. basilicum ethanol extract against all pathogenic bacteria was significantly (p ≤ 0.05) greater than hexane and acetone extracts. Lactobacillus isolates were shown the highest antimicrobial activity than the other LAB isolates against all pathogens. The synergistic effect of spices together with LAB might be contributed a lot to preserve and extend shelf life of metata ayib. Their antimicrobial activity can reduce the risk of spoilage and pathogenesis. The possible reason of LAB isolates was may be due to production of lactic acid, acetic acid and secondary metabolites like bacteriocins. Aseptic processing of traditional cottage cheese (ayib) is by far needed to minimize risks associated during consumption of metata ayib. PMID:26344979

    The trapping of lipid-laden macrophages in the arterial intima is a critical but reversible step in atherogenesis. However, information about possible treatments for this condition is lacking. Here, we hypothesized that combining the polyphenol-rich fractions (PHC) of commonly consumed spices (Allium sativum L (Liliaceae), Zingiber officinale R (Zingiberaceae), Curcuma longa L (Zingiberaceae)) and herbs (Terminalia arjuna (R) W & A (Combretaceae) and Cyperus rotundus L (Cyperaceae)) prevents foam cell formation and atherogenesis. Using an in vitro foam cell formation assay, we found that PHC significantly inhibited lipid-laden macrophage foam cell formation compared to the depleted polyphenol fraction of PHC (F-PHC). We further observed that PHC attenuated the LDL and LPS induced CD36, p-FAK and PPAR-γ protein expression in macrophages and increased their migration. NK-κB-DNA interaction, TNF-α, ROS generation, and MMP9 and MMP2 protein expression were suppressed in PHC-treated macrophages. The anti-atherosclerotic activity of PHC was investigated in a high fat- and cholesterol-fed rabbit model. The inhibition of foam cell deposition within the aortic intima and atheroma formation confirmed the atheroprotective activity of PHC. Therefore, we conclude that the armoury of polyphenols in PHC attenuates the CD36 signalling cascade-mediated foam cell formation, enhances the migration of these cells and prevents atherogenesis.

  16. Gamma irradiation technology for the preservation of spices and fruits (1991-1993)

    International Nuclear Information System (INIS)

    The application of gamma irradiation technology to improve the hygienic quality of selected Sri Lankan spices including pepper, nutmeg, cardamon, cinnamon and cloves was examined. Microbial decontamination was achieved with an irradiation dose of 7.5 kGy with respect to the above spices. No microbial growth occurred in the irradiated spices during a subsequent 6 months storage. Studies on the essential oil content and volatile oil components of these spices confirmed the absence of appreciable changes in the quality of irradiated samples when treated with irradiation dosage up to 10 kGy. Satisfactory results were also obtained with respect to microbial decontamination and chemical composition in inter-country transportation and storage trials on pepper and turmeric samples shipped from India to Sri Lanka and stored for a period of 12 months. A preliminary consumer acceptance survey indicated a reluctance to use irradiated spices and a low level of awareness on the applicability and benefits of irradiation with respect to the improvement in hygienic quality.

    The SPICE (Spectral Imaging of the Coronal Environment) instrument is one of the key remote sensing instruments onboard the upcoming Solar Orbiter Mission. SPICE has been designed to contribute to the science goals of the mission by investigating the source regions of outflows and ejection processes which link the solar surface and corona to the heliosphere. In particular, SPICE will provide quantitative information on the physical state and composition of the solar atmosphere plasma. For example, SPICE will access relative abundances of ions to study the origin and the spatial/temporal variations of the 'First Ionization Potential effect', which are key signatures to trace the solar wind and plasma ejections paths within the heliosphere. Here we will present the instrument and its performance capability to attain the scientific requirements. We will also discuss how different observation modes can be chosen to obtain the best science results during the different orbits of the mission. To maximize the scientific return of the instrument, the SPICE team is working to optimize the instrument operations, and to facilitate the data access and their exploitation.

    Full Text Available In recent years, it has been acknowledged that many spices not only have properties that make food more pleasant and tastier but they also have important preservative and antioxidant properties. The antioxidant properties of many spices are well known, while their prooxidant properties less so. The aim of this study was to perform a comparative evaluation of three selected spice (garlic, black pepper and red pepper, commercially available in Cluj-Napoca’s market, regarding their content in total phenolic compounds, antioxidant capacity and antimicrobial activity. The antioxidant aspects were evaluated by determination of the total phenolic content by the Folin-Ciocalteau method and by the antioxidant activity using the 1,1-diphenyl-2-picrylhydrazyl reagent (DPPH.The total phenolic content was between 3,38 and 0,925 mg GAE/1g, while the antioxidant capacity ranged between 18,41% and 10,9% from dry spice. .Results  showed that garlic extract has the most effective antioxidant capacity in scavenging DPPH radicals, while black pepper and red pepper were less active. In the present study piperine was evaluated for its antimicrobial activity against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Salmonella typhumurium. Spices showed antimicrobial activity against all tested bacteria with zone of inhibition ranged from 8-15,5 mm.

  19. Effect of electron-beams irradiation for inactivation of microorganisms on spices

    International Nuclear Information System (INIS)

    Total aerobic bacteria in spices used in this study were determined to be 1x106 to 6x107 per gram. A study on the inactivation of microorganisms in spices showed that doses of 6 to 9 kGy of EB (electron-beams) or gamma irradiation were required to reduce the total aerobic bacteria tobelow 103 per gram. However, a little increase of resistance was observed on the inactivation of total aerobic bacteria in many spices in case of EB irradiation. These difference of radiation sensitivities between EB and gamma-rays was explained by dose rate effect on oxidation damage to microorganisms from the results of radiation sensitivities of Bacillus pumilus and B. megaterium spores at dry conditions. On the other hand, these high dose rate of EB irradiation suppressed the increase of peroxide values in spices at high dose irradiation up to 80 kGy. Components of essential oils in spices were not changed even irradiated up to 50 kGy with EB and gamma-rays. (author)

    A colorimetric method for the determination of total antioxidant activity in a variety of foods and beverages was validated in both a single-laboratory validation and a collaborative laboratory validation study. The procedure involved extraction of the antioxidants directly into a methanol-water solution containing a known amount of 2,2'-diphenyl-1-picrylhydrazyl (DPPH), thus promoting the rapid reaction of extracted materials with DPPH. The reaction was monitored by spectrophotometric measurement of the absorbance loss at 517 nm. Antioxidant activity was quantified relative to a dilution series of vitamin E analog standards (Trolox), which were analyzed in parallel simultaneously with the food and beverage samples. The antioxidant activities of the samples ranged from 131 to 131 000 micromole Trolox equivalents/100 g. Statistical analysis of the results showed that nine of the 11 matrixes gave acceptable HorRat values, indicating that the method performed well in these cases. The acceptable matrixes include pomegranate juice, blueberry juice, carrot juice, green tea, wine, rosemary spice, ready-to-eat cereal, and yogurt. Two samples failed the HorRat test: the first was an almond milk that had an antioxidant level below the practical LOQ for the method; the second was a sample of canola oil with added omega-3 fatty acid that was immiscible in the reaction medium.

    Full Text Available Rheological properties of fermented dairy products are very important parameters of the product quality. The behaviour of gel formed during fermentation of milk is influenced by a great number of factors, such as: milk composition, starter culture, flavourings addition, etc. The aim of this research was to examine the influence of fat content, and kombucha inoculum concentration on textural characteristics of fermented milk beverages: firmness, consistency, cohesiveness and viscosity index after production and during 10 days of storage. Higher fat content of beverage affects the firmness, consistency, cohesiveness and viscosity index, while higher amount of inoculum in beverages has an opposite effect on textural characteristics of samples during storage.

  8. Circuit models and SPICE macro-models for quantum Hall effect devices

    International Nuclear Information System (INIS)

    Precise electrical measurement technology based on the quantum Hall effect is one of the pillars of modern quantum electrical metrology. Electrical networks including one or more QHE elements can be used as quantum resistance and impedance standards. The analysis of these networks allows metrologists to evaluate the effect of the inevitable parasitic parameters on their performance as standards. This paper presents a concise review of the various circuit models for QHE elements proposed in the literature, and the development of a new model. This last model is particularly suited to be employed with the analogue electronic circuit simulator SPICE. The SPICE macro-model and examples of SPICE simulations, validated by comparison with the corresponding analytical solution and/or experimental data, are provided. (paper)

    Objective of this study was to determine the content of Cd, Hg, As and Pb in common spices traded in the Italian market, using inductively coupled plasma-mass spectrometry (ICP-MS). The results were compared with the maximum limits established by the national Legislative Decree (LD) no. 107 implementing the Council Directive 88/388/EEC and by international organisations, such as Food and Agriculture Organization (FAO) and World Health Organization (WHO). Food safety for spices was assessed considering the tolerable weekly intake (TWI) and the provisional tolerable weekly intake (PTWI), respectively, for Cd and Hg and the 95% lower confidence limit of the benchmark dose of 1% extra risk (BMDL01) for As and Pb. Investigated elements in all samples were within the maximum limits as set by the national and international normative institutions. Nevertheless, the heavy metal content of some spices exceeded the PTWI, TWI and BMDL01, which needs attention when considering consumer's health. PMID:27074712

    The globally recognized Late Cambrian Steptoean positive C-isotope excursion (SPICE) is characterized by a 3???-5??? positive ??13C shift spanning <4 m.y. Existing hypotheses suggest that the SPICE represents a widespread ocean anoxic event leading to enhanced burial/preservation of organic matter (Corg) and pyrite. We analyzed ??18O values of apatitic inarticulate brachiopods from three Upper Cambrian successions across Laurentia to evaluate paleotemperatures during the SPICE. ??18O values range from ~12.5??? to 16.5???. Estimated seawater temperatures associated with the SPICE are unreasonably warm, suggesting that the brachiopod ??18O values were altered during early diagenesis. Despite this, all three localities show similar trends with respect to the SPICE ??13C curve, suggesting that the brachiopod apatite preserves a record of relative ??18O and temperature changes. The trends include relatively high ??18O values at the onset of the SPICE, decreasing and lowest values during the main event, and an increase in values at the end of the event. The higher ??18O values during the global extinction at the onset of the SPICE suggests seawater cooling and supports earlier hypotheses of upwelling of cool waters onto the shallow shelf. Decreasing and low ??18O values coincident with the rising limb of the SPICE support the hypothesis that seawater warming and associated reduced thermohaline circulation rates contributed to decreased dissolved O2 concentrations, which enhanced the preservation/burial of Corg causing the positive ??13C shift. ?? 2011 Geological Society of America.

    The purpose of this study was to determine total water intake and patterns of beverage consumption, and its contribution to total daily micronutrients and calories in older adults with mild memory decline. A descriptive, cross-sectional study was used with 60 independent community-dwelling older adults (71.7 ± 5.4 years) with mild cognitive impairment, who were mostly female, well-educated, and white. Three-day food records were analyzed using the Nutrition Data Systems for Research. Descriptive statistics were conducted for a summary of demographics, the average intakes of beverages, and the contribution of beverages to total calorie and micronutrient intakes. Total daily water intake was 53.6 ± 26.7 fl oz and milk, plain water, and tea/coffee were beverages consumed most frequently. Beverage consumption contributed substantially to the intake of vitamin D (29.4%), calcium (26.4%), riboflavin (22.0%), magnesium (18.9%), and vitamin C (18.1%), but constituted only ∼12.5% of total energy. These findings suggest that nutrient-dense beverages play a fundamental role in overall micronutrient intake, despite comprising a small component of daily caloric intake. Incorporating adequate amounts of such beverages in meals and snacks may help older adults meet their nutrient recommendations. PMID:26571357

    The scattering of X-rays at low angles (LAXS) is a technique dominated by the coherent scattering process. One characteristic observation of low-angle coherent scattering is the so-called molecular interference effect, being characterized by the presence of one or more peaks in the forward direction of scattering. In the present study, LAXS profiles from five different spices are carefully measured in order to establish characteristic scattering signatures. Samples of Ceylon cinnamon, cumin, nutmeg, paprika and black pepper were bought in local market in Rio de Janeiro, Brazil. The LAXS patterns were obtained using a Shimadzu DRX 6000 diffractometer in reflection geometry. Coherent scattering patterns are measured for the samples for {theta}=5-35{sup o}. The data were collected in 0.05{sup o} increments every 3 s. In order to evaluate the possible molecular structure changes caused to the irradiation procedure, the signatures obtained for control (non-irradiated) spices were compared with spice samples irradiated with different doses varying from 3 to 40 kGy. The LAXS patterns of all samples were obtained after 30, 60, 90, 120 days to evaluate the effect of storage period. Scattering profiles from spices irradiated with different irradiation doses were obtained and the results compared. For each spice, there is no considerable deviation in shape in function of the irradiation dose. It indicates that the molecular structure of each analyzed spices is preserved considering the dose range chosen. The results show that the molecular structure was found to be stable during storage at the ambient temperature for up to 4 months.

    Spices from Egyptian local markets were irradiated with different recommended doses (0, 5, 10, 20 and 30 kGy). The spices tested included dried leaves of marjoram (Majorana hortensis Moench), rhizomes of ginger (Zingiber officinale Roscoe) and powdered hot pepper (Capsicum annum L.). The study included the isolation and identification of micro-organisms in spices following their irradiation, as well as gas chromatographic (GLC) chemical analysis for the presence and structure of volatile oils, pungent and pigment materials. The results showed that hot pepper was contaminated more (9.2x105/g) than marjoram (4.2x103/g) and ginger (14.3x103/g) with respect to total aerobic bacterial content. The total contents of moulds were 4.8x103/g, 5.7x103/g and 19x103/g in the same spices, respectively, but the pathogenic moulds and bacterial strains differed according to the type of spice. Irradiation at 10, 20 and 30 kGy caused complete elimination of mirco-organisms, whereas 5 kGy was less effective. With the GLC method chosen 18 and 50 compounds could be detected in the extracts of marjoram and ginger, respectively; γ-terpinen and zingiberen being the major compounds in marjoram and ginger, respectively. A noticeable reduction was observed in the amount of terpenes present in irradiated marjoram; they were converted to monoterpensalcohols. Ginger was more sensitive to irradiation, especially at high doses, but moderate changes were detected at low doses (5 and 10 kGy). A slight, but significant effect on the capsaicin (pungent compound) in hot pepper was observed following irradiation, whereas no changes in total pigments resulted at any dose. These results prove that 10 kGy is a sufficiently high dose to eliminate the microorganisms in spices, causing only slight changes in the flavouring materials. (orig.)

    Full Text Available Diabetes mellitus is a public health problem which leads to serious complications over time. Experimentally, many herbs have been recommended for treating diabetes. In most cases, however, the recommendations are based on animal studies and limited pieces of evidence exist about their clinical usefulness. This review focused on the herbs, the hypoglycemic actions of which have been supported by three or more clinical studies. The search was done in Google Scholar, Medline and Science Direct databases using the key terms diabetes, plants, herbs, glucose and patients. According to the clinical studies, Aegle marmelos, Allium cepa, Gymnema sylvestre, Momordica charantia, Ocimum sanctum, Nigella sativa, Ocimum sanctum, Panax quinquefolius, Salacia reticulate, Silybum marianum and Trigonella foenum-graecum have shown hypoglycemic and, in some cases, hypolipidemic activities in diabetic patients. Among them, Gymnema sylvestre, Momordica charantia, Silybum marianum and Trigonella foenum-graecum have acquired enough reputation for managing diabetes. Thus, it seems that physicians can rely on these herbs and advise for the patients to improve management of diabetes.

    For ages, herbs have been used as medicine and food. Nowadays, the interest in phytotherapeutics is increasing as well as the consumer attention. Some biochemical compounds synthesized by plants as alkaloids, phenolics, flavonoids, essential oils, tannins and vitamins, influence the composition of these plant pharmacologicals, which may produce various reactions in the human body. The microbial contamination in these raw plant materials is common, and the radiation processing is one appropriate technique for the reduction of microorganism. In herbs used as food products, the changes in total β-carotene and flavonoids upon the radiation treatment were tested. The powdered and dehydrated herbs were irradiated with 60Co gamma rays applying doses of 0, 10, 20 and 30 kGy. The botanical species investigated were rosemary ( Rosmarinus officinalis Linné), watercress ( Nasturtium officinale R. Br), artichoke ( Cynara scolymus Linné) and sweet basil ( Ocimum basilicum Linné). The alterations in the active principles in the herbs following increasing doses of radiation were analyzed employing various methods of extraction and chromatography.

    2015-10-01

    This paper aims to analyze Professor Guo Rongjuan's medication experience on insomnia therapy based on the Traditional Chinese Medicine (TCM) Inheritance Support Plat. First, TCM formulae prescribed by Professor Guo for insomnia therapy were collected from the TCM Inheritance Support Plat. Next, unsupervised data mining algorithms, including apriori, modified mutual-information, and entropy clustering of complex system were applied to obtain the frequencies for different herbs and identify the association rules among the herbs. Accordingly, we can gain new insights into Professor Guo's medication experience on insomnia therapy. Based on analysis of 3 084 formulae, we determined the frequencies for herbs in the formulae and identified the association rules among these herbs. At last, 41 core combinations and 7 new formulae were obtained. The identified medication experience conform with Professor Guo's views on the etiology and pathogenesis of insomnia: "pathogenic fire derived from stagnation of liver-QI (Gan Yu Hua Huo)" is the core pathogenesis of insomnia; "liver stagnation and spleen deficiency" and "chronic illness transferred to kidney" are the main features for insomnia. The TCM Inheritance Support Plat is of great practical value for mining clinical experience of famous TCM doctors. PMID:26975117

  4. Economics of irradiation of spices and vegetable seasonings in comparison with other methods of treatment used commercially

    International Nuclear Information System (INIS)

    Spices are known to be contaminated with organisms such as pathogenic bacteria, moulds, yeasts and also insect and animal residues. Post-harvest examinations of certain spices have demonstrated very high microbial contamination, thus even when these spices are used sparingly in the food processing industry, if the end product, e.g. fresh sausages, salad dressings, has not been precooked, spoilage of such products reduces their values in the market-place. Proper cleaning techniques are therefore essential in removing or reducing infestations. Spices can be treated by one of three such techniques available in the USA. These use ethylene oxide gas (ETO), steam, and sterilization by irradiation, respectively. The paper investigates the economics of using irradiation on spices (including dehydrated vegetable seasonings) in comparison with ETO treatment. (author). 2 refs, 2 tabs

    Three experiments were conducted to assess the antioxidant efficacy of spice extracts in cooked meat. In experiment 1, antioxidant activity of 13 common spice extracts was screened in a liposome system. Six of the extracts (clove, rosemary, cassia bark, liquorice, nutmeg, and round cardamom), identified to have the greatest total phenolic contents, were strongly inhibitory of TBARS formation. In experiment 2, 2,2-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, ferric-reducing power, and metal chelation of these six spice extracts were evaluated. Clove exhibited the greatest reducing power, and all had strong DPPH scavenging activity. In experiment 3, clove, rosemary, and cassia bark extracts were further tested for in situ antioxidant efficacy. Cooked pork patties containing these spice extracts had markedly reduced TBARS formation and off-flavour scores but a more stable red colour, during storage. The results demonstrated strong potential of spice extracts as natural antioxidants in cooked pork products. PMID:20430533

    Olive oil flavouring with aromatic plants and spices is a traditional practice in Mediterranean gastronomy. The aim of this work was to compare the influence of two different flavouring techniques (infusion of spices into the oil vs. combined malaxation of olives paste and spices) on chemical and sensory quality of flavoured olive oil. In particular, oxidative and hydrolytic degradation (by routine and non-conventional analyses), phenolic profiles (by HPLC), volatile compounds (by SPME-GC/MS), antioxidant activity, and sensory properties (by a trained panel and by consumers) of the oils were evaluated. The obtained results evidenced that the malaxation method was more effective in extracting the phenolic compounds, with a significantly lower level of hydrolysis of secoiridoids. As a consequence, antioxidant activity was significantly lower in the oils obtained by infusion, which were characterized by a higher extent of the oxidative degradation. The volatile compounds were not significantly influenced by changing the flavouring method, apart for sulfur compounds that were more abundant in the oils obtained by the combined malaxation method. From a sensory point of view, more intense bitter and pungent tastes were perceived when the infusion method was adopted. PMID:26920288

    Obesity rates among U.S. adults and children have increased over the past two decades and, although signs of stabilization and decline among certain age groups and geographies are being reported, the prevalence of obesity among Latino adults and children remain high. The Latino population is growing in parallel to these obesity rates and marketers realize they cannot ignore this growing, high-spending, media-consuming segment. Studies examining food and beverage marketing strategies tend to discuss minority groups in general but do not account for racial and ethnic differences, reducing our ability to explain existing inequities. This article aimed to identify the food and beverage marketing strategies used to influence food environments for Latinos versus non-Latinos. A systematic literature review and analysis, guided by an established marketing conceptual framework, determined that the food and beverage marketing environment for Latinos is less likely to promote healthy eating and more likely to encourage consumption of low-nutrient, calorie-dense foods and beverages. This analysis also determined that Latinos' food environment and the placement of food retail stores appears to influence their body mass index; however, placement of these stores cannot be generalized, as geographical differences exist. While food and beverage marketing is only one of many sources of influence on food and beverage consumption, these findings reinforce the notion that Latinos are at a disadvantage when it comes to exposure of healthy lifestyle messaging and health-promoting food environments.

    Neurodegenerative diseases, referring to as the progressive loss of structure and function of neurons, constitute one of the major challenges of modern medicine. Traditional Chinese herbs have been used as a major preventive and therapeutic strategy against disease for thousands years. The numerous species of medicinal herbs and Traditional Chinese Medicine (TCM) compound formulas in nervous system disease therapy make it a large chemical resource library for drug discovery. In this work, we collected 7362 kinds of herbs and 58,147 Traditional Chinese medicinal compounds (Tcmcs). The predicted active compounds in herbs have good oral bioavailability and central nervous system (CNS) permeability. The molecular docking and network analysis were employed to analyze the effects of herbs on neurodegenerative diseases. In order to evaluate the predicted efficacy of herbs, automated text mining was utilized to exhaustively search in PubMed by some related keywords. After that, receiver operator characteristic (ROC) curves was used to estimate the accuracy of predictions. Our study suggested that most herbs were distributed in family of Asteraceae, Fabaceae, Lamiaceae and Apocynaceae. The predictive model yielded good sensitivity and specificity with the AUC values above 0.800. At last, 504 kinds of herbs were obtained by using the optimal cutoff values in ROC curves. These 504 herbs would be the most potential herb resources for neurodegenerative diseases treatment. This study would give us an opportunity to use these herbs as a chemical resource library for drug discovery of anti-neurodegenerative disease. PMID:26898452

    Convolvulus pluricaulis Choisy (C. pluricaulis) is a perennial herb that seems like morning glory. All parts of the herb are known to possess therapeutic benefits. The plant is used locally in Indian and Chinese medicine to cure various diseases. It is used in Ayurvedic formulation for chronic cough, sleeplessness, epilepsy, hallucinations, anxiety etc. Based on the comprehensive review of plant profile, pharmacognosy, phytochemistry, pharmacological and toxicological data on the C. pluricaulis, there will be more opportunities for the future research and development on the herb C. pluricaulis. Information on the C. pluricaulis was collected via electronic search (using Pub Med, SciFinder, Google Scholar and Web of Science) and library search for articles published in peer-reviewed journals. Furthermore, information also was obtained from some local books on ethnopharmacology. This paper covers the literature, primarily pharmacological, from 1985 to the end of 2012. The C. pluricaulis is an important indigenous medicine, which has a long medicinal application for liver disease, epileptic disease, microbial disease, cytotoxic and viral diseases, central nervous system (CNS) disease in Ayurvedic medicine, traditional Chinese medicine and other indigenous medical systems. The isolated metabolites and crude extract have exhibited a wide of in vitro and in vivo pharmacological effect, including CNS depression, anxiolytic, tranquillizing, antidepressant, antistress, neurodegenerative, antiamnesic, antioxidant, hypolipidemic, immunomodulatory, analgesic, antifungal, antibacterial, antidiabetic, antiulcer, anticatatonic, and cardiovascular activity. A chemical study of this plant was then initiated, which led to the isolation of carbohydrats, proteins, alkaloids, fatty acids, steroids, coumarins, flavanoids, and glycosides as active chemicals that bring about its biological effects. A series of pharmacognostical studies of this plant show that it is a herb, its stem and

    In this paper the results of the investigations of identification of irradiated spices by the use of thermoluminescence method is reported. The materials used were black and red peppers, turmeric, cinnamon, and garlic powder. Gamma Cell 220 was used for irradiating samples at dose values of 2.5, 5, 7.5 and 10 kGy respectively. The TL intensity of the unirradiated spices as well as the fading characteristics of the irradiated samples having received a dose of 10 kGy have been measured. Post-irradiation temperature treatment of the irradiated (10 kGy) and unirradiated samples at 60°C and 100°C for 24 hours have been also performed. The results show that the TL intensities of unirradiated and irradiated samples from different batches of each spice are fairly distributed. A reasonable TL intensity versus dose has been observed in nearly all cases. Based on the observations made it is possible to distinguish irradiated spices after (4-9) months post-irradiation.

    In this paper the results of the investigation of identification of irradiated spices by the use of thermoluminescence method is reported. The materials used were black and red peppers, turmeric, cinnamon, and garlic powder. Gamma Cell 220 was used for irradiating samples at dose values of 2.5, 5, 7.5 and 10 kGy respectively. The TL intensity of the unirradiated spices as well as the fading characteristics of the irradiated samples having received a dose of 10 kGy have been measured. Post-irradiation temperature treatment of the irradiated (10 kGy) and unirradiated samples at 60oC and 100oC for 24 hours have also been performed. The results show that the TL intensities of unirradiated and irradiated samples from different batches of each spice are fairly distributed. A reasonable TL intensity versus dose has been observed in nearly all cases. Based on the observation made it is possible to distinguish irradiated spices after (4-9) months post-irradiation.

    Quorum sensing (QS) is a signaling mechanism used by bacteria to communicate each other through the release of auto-inducing signaling molecules. Despite the fact that bacteria regulate its phenotypes by QS mechanism, their potential role in meat spoilage is not yet elucidated. In the current study, beef samples were analyzed for its microbial association and for the presence of N-acyl-homoserine-lactone (AHLs) throughout the storage experiments. Isolates were screened for AHLs production and selected spices were screened for their quorum sensing inhibitory (QSI) activity. In addition, effect of spices on AHLs production of Y. enterocolitica was quantified through high performance thin layer chromatography (HP-TLC). Outcome showed that microbial association of beef mainly consists of lactic acid bacteria (LAB) and Enterobacteriaceae. Samples stored at both aerobic and modified atmospheric packaging (MAP) exhibited higher counts whereas; marinated samples stored at MAP exhibited the lowest. It was found that out of 35 isolates Y. enterocolitica induced reporter strain CV026 and its cell-free supernatant contained 26.36 nM/100 ml of AHLs when compared to standard. Among the tested spices, C. cyminum exhibited pronounced results by significantly reducing the AHLs concentration up to 47.75 %. Findings revealed the presence of quorum molecules (AHLs) in beef meat throughout the spoilage process and spices can acts as quorum quenchers to influence the spoilage rate by reducing AHLs production.

  12. SPICE modelling of magnetic tunnel junctions written by spin-transfer torque

    International Nuclear Information System (INIS)

    Spintronics aims at extending the possibility of conventional electronics by using not only the charge of the electron but also its spin. The resulting spintronic devices, combining the front-end complementary metal oxide semiconductor technology of electronics with a magnetic back-end technology, employ magnetic tunnel junctions (MTJs) as core elements. With the intent of simulating a circuit without fabricating it first, a reliable MTJ electrical model which is applicable to the standard SPICE (Simulation Program with Integrated Circuit Emphasis) simulator is required. Since such a model was lacking so far, we present a MTJ SPICE model whose magnetic state is written by using the spin-transfer torque effect. This model has been developed in the C language and validated on the Cadence Virtuoso Platform with a Spectre simulator. Its operation is similar to that of the standard BSIM (Berkeley Short-channel IGFET Model) SPICE model of the MOS transistor and fully compatible with the SPICE electrical simulator. The simulation results obtained using this model have been found in good accord with those theoretical macrospin calculations and results.

    Full Text Available Spices are some of the most common foods in the human diet around the world. Spices are dried parts of plants used often as diet components to improve aroma and acceptability of food. The aim of this work was to determine the contents of seven heavy metals (Cr, Cu, Fe, Mn, Ni, Pb and Zn in spices available at local markets in Sarajevo. Metal concentrations in six spice samples (black pepper (Piper nigrum, basil (Ocimum basilicum, oregano (Oreganum vulgaris, paprika (Capsicum annuum, parsley (Petroselinum crispum and rosemary (Rosmarinus officinalis were determined by flame atomic absorption spectrometry. The content of chromium and nickel in all samples was below 5 mg kg-1 . Copper levels were in the range of 2.36-19.47 mg kg-1 , iron 6.80-785.56 mg kg-1 , manganese 6.14-59.36 mg kg-1 , lead 0.74-20.35 and zinc 6.93-85.44 mg kg-1 . These results were in agreement with other published data except in the case of Pb which content was slightly higher. Daily intake of different metals was calculated and compared with the MRL values given by ATSDR (2013. The content of lead in most of the samples was above the maximum permitted concentrations recommended by WHO and national regulations of Bosnia and Herzegovina.

    Although most cases of childhood lead poisoning are caused by contaminated paint and dust in older homes, a variety of unusual sources of lead exposure are occasionally found. We report here 2 families whose children were poisoned by lead-contaminated spices that were purchased in foreign countries, brought to the United States, and then used in the preparation of the family's food. Six children (2-17 years old) in a family from the Republic of Georgia were poisoned by swanuri marili (lead content: 100 and 2040 mg/kg in separately sampled products) and kharchos suneli (zafron) lead content: 23,100 mg/kg) purchased from a street vendor in Tbilisi, Georgia. The second family had purchased a mixture of spices called kozhambu (lead content: 310 mg/kg) while traveling in India. Both the parents and their 2-year-old child subsequently suffered lead poisoning. The young children in both families required short-term chelation to bring their blood lead levels down to a safer range. Clinicians should be vigilant for all sources of lead contamination, including spices, when whole families are found to have elevated blood lead levels despite a confirmed lead-safe home environment. Families traveling abroad should be aware of the potential health risks associated with the purchase and use of spices that have not been tested for purity. PMID:16061585

    A risk benefit assessment in Norway on the intake of added sugar, intense sweeteners and benzoic acid from beverages, and the influence of changing from sugar sweetened to diet beverages was performed. National dietary surveys were used in the exposure assessment, and the content of added sugar and food additives were calculated based on actual contents used in beverages and sales volumes provided by the manufactures. The daily intake of sugar, intense sweeteners and benzoic acid were estimated for children (1- to 13-years-old) and adults according to the current intake level and a substitution scenario where it was assumed that all consumed beverages contained intense sweeteners. The change from sugar sweetened to diet beverages reduced the total intake of added sugar for all age groups but especially for adolescent. This change did not result in intake of intense sweeteners from beverages above the respective ADIs. However, the intake of acesulfame K approached ADI for small children and the total intake of benzoic acid was increased to above ADI for most age groups. The highest intake of benzoic acid was observed for 1- to 2-year-old children, and benzoic acid intake in Norwegian children is therefore considered to be of special concern. PMID:18639604

    Full Text Available The effect of selected spices included in the recipe of rye-buckwheat cakes on sensory quality, nutritional value, and Maillard reaction (MR products formation was addressed in this study. The cakes with cloves, nutmeg, allspice, cinnamon, vanilla, and spice mix addition revealed the highest overall quality values. Cakes enriched with cloves, allspice, and spice mix showed the highest rutin content and almost threefold higher available lysine contents whereas cakes enhanced with mix, cloves, and cinnamon were the richest source of phenolic compounds. The highest antioxidant capacity showed cakes with cloves and spice mix. The furosine, a marker of early stage of MR, was decreased in cakes with cloves, allspice, spice mix, and vanilla whereas fluorescent intermediatory compounds were reduced in cakes enhanced with cloves, allspice, and cinnamon. In contrast, browning index was increased as compared to cakes without spices. The FAST index was significantly lowered in all cakes enriched with spices, especially with cloves, allspice, and mix addition. The presence of cloves, allspice, and vanilla in cake formula was the most efficient in acrylamide strategy. It can be suggested that cloves, allspice, and vanilla might be used for production of safety and good quality cakes.

    Full Text Available The main fermented meat products are fermented sausages in which lactic acid bacteria (LAB are the essential agents of the ripening process. Their application as starter organisms ensures the dominance of the starter during the whole ripening process. However, when no starter cultures are used, direct addition of acids like a glucono-delta-lactone (GdL is preferred. The goal of this study was to determine the influence of commercial spices mixtur (containing GdL on selected technological parameters of fermented dry-cured sausages - Danube sausage in comparison with currently available conventional spices. Comparison was evaluated also with addition of starter cultures. Determinations of technological (value of pH, water activity, color and microbiological properties (count of Lactobacillus spp., Enterobacteriaceae family, yeasts and moulds were realized after 24 hours, 5 and 30 days. The sensory analysis of sausages was carried out after 30 days of ripening process. In sausages with the addition of commercial spice mixture in combination with starter culture were determined the lowest values of pH and aw at the end of ripening process (30 days. Bacteria of Enterobacteriaceae family were occurred in the samples with the addition of currently available conventional spices at the beginning of ripening, but after 5 days of ripening were bacteria of this family not detected. The counts of yeasts in analyzed samples were not detected. Counts of LAB at the end of ripening proccess (30 days were lower in coparison with result obtained after 5 days; however their count was comparable with count determined at the beginig of the ripening. Our results show, that the combination of starter culture and commercial spice mixture containig GdL may cause excesive sour taste and sensory defect of dry fermented meat products.

    Full Text Available Abstract Poor quality control of medicinal herbs has led to instances of toxicity, poisoning and even deaths. The fundamental step in quality control of herbal medicine is accurate identification of herbs. Array-based techniques have recently been adapted to authenticate or identify herbal plants. This article reviews the current array-based techniques, eg oligonucleotides microarrays, gene-based probe microarrays, Suppression Subtractive Hybridization (SSH-based arrays, Diversity Array Technology (DArT and Subtracted Diversity Array (SDA. We further compare these techniques according to important parameters such as markers, polymorphism rates, restriction enzymes and sample type. The applicability of the array-based methods for fingerprinting depends on the availability of genomics and genetics of the species to be fingerprinted. For the species with few genome sequence information but high polymorphism rates, SDA techniques are particularly recommended because they require less labour and lower material cost.

    Full Text Available Herbs have been used in medicines and cosmetics from centuries. Their potential to treat different skin diseases, to adorn and improve the skin appearance is well-known. As ultraviolet (UV radiation can cause sunburns, wrinkles, lower immunity against infections, premature aging, and cancer, there is permanent need for protection from UV radiation and prevention from their side effects. Herbs and herbal preparations have a high potential due to their antioxidant activity, primarily. Antioxidants such as vitamins (vitamin C, vitamin E, flavonoids, and phenolic acids play the main role in fighting against free radical species that are the main cause of numerous negative skin changes. Although isolated plant compounds have a high potential in protection of the skin, whole herbs extracts showed better potential due to their complex composition. Many studies showed that green and black tea (polyphenols ameliorate adverse skin reactions following UV exposure. The gel from aloe is believed to stimulate skin and assist in new cell growth. Spectrophotometer testing indicates that as a concentrated extract of Krameria triandra it absorbs 25 to 30% of the amount of UV radiation typically absorbed by octyl methoxycinnamate. Sesame oil resists 30% of UV rays, while coconut, peanut, olive, and cottonseed oils block out about 20%. A "sclerojuglonic" compound which is forming from naphthoquinone and keratin is the reaction product that provides UV protection. Traditional use of plant in medication or beautification is the basis for researches and making new trends in cosmetics. This review covers all essential aspects of potential of herbs as radioprotective agents and its future prospects.

    Full Text Available One of the challenges of studying food consumption behavior is to identify the drivers of choice for a food product. This is particularly important to design and develop new foods for which no previous information is available. Hibiscus sabdariffa L. (Bissap is an herbaceous plant and an important source of vitamins, minerals, and bioactive compounds, which confer a number of potential health benefits to derived products. The consumption of Bissap in beverage form is widespread in Africa and Asia, but not yet in Europe. Therefore, this study aimed to identify the main drivers of consumer acceptance of a traditional African beverage made from Bissap to which they had not been previously exposed. First, three focus groups (n = 22 were performed in Portugal to characterize the sensory profile of four Bissap beverages, to reveal perceptions and attitudes towards Bissap beverages, and to identify potential choice attributes. Subsequently, a full-profile conjoint analysis (n = 99 was performed, where consumers evaluated 37 Bissap beverage profiles, aiming to estimate choice attribute importance and to identify relevant market segments. Focus group findings showed that consumers would choose Bissap because they perceived as a healthy choice, and due to its novelty. The conjoint study showed an ideal profile for a Bissap beverage costing €0.99/L, <18 kcal/100 mL, packaged in Tetra-pack, light red color, and containing labeling information about antioxidants and Bissap. Four clusters of consumers were identified: price sensitive, body concerned, packaging attracted, and demanding, highlighting the most influential choice attributes: price, calories, and packaging. Findings provide useful guidance for new product development of an African product in the European lifestyle. Results might be useful from a nutraceutical point of view and to the food/beverages industry.

    Food protein-induced enterocolitis syndrome (FPIES) is an uncommon and potentially severe non IgE-mediated gastrointestinal food allergy. It is usually caused by cow's milk or soy proteins, but may also be triggered by ingestion of solid foods. The diagnosis is made on the basis of clinical history and symptoms. Management of acute phase requires fluid resuscitation and intravenous steroids administration, but avoidance of offending foods is the only effective therapeutic option.Infant with FPIES presented to our emergency department with vomiting, watery stools, hypothension and metabolic acidosis after ingestion of rice beverage. Intravenous fluids and steroids were administered with good clinical response. Subsequently, a double blind placebo control food challenge (DBPCFC) was performed using rice beverage and hydrolyzed formula (eHF) as placebo. The "rice based formula" induced emesis, diarrhoea and lethargy. Laboratory investigations reveal an increase of absolute count of neutrophils and the presence of faecal eosinophils. The patient was treated with both intravenous hydration and steroids. According to Powell criteria, oral food challenge was considered positive and diagnosis of FPIES induced by rice beverage was made. Patient was discharged at home with the indication to avoid rice and any rice beverage as well as to reintroduce hydrolyzed formula. A case of FPIES induced by rice beverage has never been reported. The present case clearly shows that also beverage containing rice proteins can be responsible of FPIES. For this reason, the use of rice beverage as cow's milk substitute for the treatment of non IgE-mediated food allergy should be avoided. PMID:23672828

    Full Text Available The effectiveness of SPICE circuit simulation program in calculating probabilities, reliability, steady-state availability and mean-time to failure of repairable systems described by Markov models is demonstrated. Two examples are presented. The first example is a warm standby system with common-cause failures and human errors. The second example is a non-identical unit parallel system with common-cause failures. In both cases recourse to numerical solution is inevitable to obtain the Laplace transforms of the probabilities. Results obtained using SPICE are compared with previously published results obtained using the Laplace transform method. Full SPICE listings are included.

    Full Text Available Cardiovascular diseases, cancer, arthritis, etc. are caused by free radicals that are byproducts of metabolic pathways. Selected plants namely Vitis vinifera, Phyllanthus emblica L., Punica granatum, Cinnamomum cassia, Ginkgo biloba L., and Camellia sinensis Linn. are reported to produce antioxidant property. This study is undertaken to support the hypothesis that formulation of a polyherbal combination of these plants shows a synergistic effect with green tea. The extracts of each drug were characterized by phytochemical studies and tests for phenolics and flavonoids. In vitro antioxidant activity for individual drug and its combination was determined by 1,1-diphenyl-2-picrylhydrazyl (DPPH, superoxide, and nitric oxide free radical scavenging methods. Our results suggest that a combination of all these herbs with green tea can synergistically enhance antioxidant activity and thus lower doses of each herb with green tea may be used. Antioxidant potential of polyherbal combination was also comparable to that of standard ascorbic acid. Studies showed that selected individual plants contained abundant quantity of phenolics and flavonoids and their polyherbal combination with green tea was found to produce best antioxidant activity among all individual extracts. This will help in avoiding undesirable side effects due to higher doses of single herb.

    Full Text Available Objective. To illustrate the difference in cold/hot natural properties and therapeutic effect of coptis-evodia herb couples by using cold/hot plate differentiating technology and microcalorimetry combined with material basis analysis in vivo and in vitro. It showed that animal retention ratio in hot pad significantly decreased along with the decrease in coptis proportion in coptis-evodia herb couples. In addition, Zuojin wan markedly reduced the retention ratio of gastritis mice in the hot pad, while Fanzuojin wan displayed an opposite result. Further, Mg2+-ATPase, Ca2+-ATPase, and T-AOC activity significantly weakened in coptis-treated group in the livers of the mice. In the gastric cells from the gastritis mice, Fanzuojin wan remarkably increased calorific value for growth and metabolism, while Zuojin wan significantly reduced the calorigenic effect. It suggested that the changes in the major chemical compositions (especially alkaloids were the material base-induced transformation between “cold” and “hot” syndromes. The material basis which affected the transformation between “cold” and “hot” syndromes might be X2, X3, X4, X8, epiberberine hydrochloride, jatrorrhizine hydrochloride, coptisine sulphate, palmatine hydrochloride, and berberine hydrochloride. The CHPD combined with microcalorimetry technology is a good method to determine the differences in the “cold” and “hot” natural properties of coptis-evodia herb couples.

    Traditional herbal medicine is driven by the use of plants or parts of plants, which have undergone minimal processing in order to treat disease and improve health. The article: "Traditional Immunosuppression--Lei Gong Teng in Modern Medicine", published in this issue of "Harefuah", raises the importance of integrating herbal medicine within the existing medical system. However, there are various limitations on integrating herbology in official frameworks, such as bureaucratic and legislative restrictions concerning the safety and efficacy of the herbs. This allows the marketing of many plants without a prescription requirement or professional advice. Another limitation relates to therapists, some of whom have not undergone proper training and may recommend the improper use of plants, resulting in a problematic combination with drugs in some cases. Regulation is necessary in order to better serve both the public and doctors. Regulation will define who is allowed to work with herbs and this will create a secure integration of herbs into the formal medical world. PMID:23957086

    The inflammatory response is one of the first defenses our body has to fight against potential endangerments. It plays a critical role in host defense, clearing and slowing the infection in the case of microbial invasion. During an inflammatory response, a variety of cytokines are produced by cells and trigger or enhance the specific inflammation response. TNFα, one of these factors, plays a crucial role in many immune and inflammatory processes, such as proliferation, apoptosis, necrosis, and cell survival. It acts in orchestrating the cytokine cascade and the major regulator of inflammatory cytokine production. Abnormality of TNFα signaling leads to many diseases, including rheumatoid arthritis, psoriasis, Crohn's disease, atherosclerosis, and cancer. Due to the importance of TNFα, regulating TNFα activity is a key to treat the related diseases. There is a long history of using medicinal herbs to treat diseases related to inflammation. We searched for an ingredient that has the ability to inhibit TNFα, we examined AO herbal extract, containing 10 individual herbs and most of these herbs have anti-inflammatory activity within humans. We have tested the anti-inflammatory ability of AO herbal extract on mice. Furthermore, we used macrophage cell from young mice and found that AO extract has the ability to reduce the inflammation by inhibiting TNFα level. PMID:26778692

    An improved method has been developed for the extraction of light filth from whole, cracked, or flaked spices (basil, bay leaves, clery leaves, chervil, chives, dill weed, mint flakes, parsley, rosemary, sage, tarragon, thyme, and vegetable flakes) and from ground spices (cloves, cumin, marjoram, mustard seed, oregano, sage, and thyme). The method involves a chloroform or isopropanol defatting, followed by a direct flotation from 40% isopropanol with Tween 80-EDTA (1+1) and mineral oil-heptane (85+15). Collaborative results show that the proposed method is more rapid to perform and yields better filth recoveries than the official first action methods for ground spices, 44.116, and whole, cracked, or flaked spices, 44.129. The method has been adopted as official first action. PMID:1170162

    Chemical analyses of ancient organics absorbed into pottery jars from the early Neolithic village of Jiahu in Henan province in China have revealed that a mixed fermented beverage of rice, honey, and fruit (hawthorn fruit and/or grape) was being produced as early as the seventh millennium before Christ (B.C.). This prehistoric drink paved the way for unique cereal beverages of the proto-historic second millennium B.C., remarkably preserved as liquids inside sealed bronze vessels of the Shang and Western Zhou Dynasties. These findings provide direct evidence for fermented beverages in ancient Chinese culture, which were of considerable social, religious, and medical significance, and help elucidate their earliest descriptions in the Shang Dynasty oracle inscriptions.

    Full Text Available Glyoxal (GO and methylglyoxal (MGO, two -dicarbonyl compounds (RCS found in humans, cause carbonyl stress following the formation of advanced glycation end products (AGEs. Both are linked to many chronic diseases. Foods, the extrinsic source, could cause the increase of RCS levels in physiological conditions. Previous data showed that high fructose corn syrup is the major source of RCS in beverages. Because of increasing consumption of syrup-sweetened beverages in Thailand, we aimed to find the GO, MGO, sugar contents, and their quantity relationship. We discovered that 70 different types of beverages contained extremely high levels of GO and MGO at maximum level of 333 and 1,208 μg/ml, respectively. All commercial syrup tested contained dicarbonyl contents, and statistics tests showed strong significant correlation between monosaccharide sugar and RCS. The total sugar contents of more than 20 tested was higher than the current daily recommendation for sugar intake to maintain health.
