    Five selected edible wild Australian mushrooms, Morchella elata, Suillus luteus, Pleurotus eryngii, Cyttaria gunnii, and Flammulina velutipes, were evaluated for their antioxidant capacity and mineral contents. The antioxidant capacities of the methanolic extracts of the dried caps of the mushrooms were determined using a number of different chemical reactions in evaluating multi-mechanistic antioxidant activities. These included the Trolox equivalent antioxidant capacity, ferric ion reducing antioxidant power, and ferrous ion chelating activity. Mineral contents of the dried caps of the mushrooms were also determined by inductively coupled plasma-optical emission spectroscopy. The results indicated that these edible wild mushrooms have a high antioxidant capacity and all, except C. gunnii, have a high level of several essential micro-nutrients such as copper, magnesium, and zinc. It can be concluded that these edible wild mushrooms are good sources of nutritional antioxidants and a number of mineral elements.

    Full Text Available The use of food medicines is a widespread practice worldwide. In Brazil, such use is often associated with wild animals, mostly focusing on vertebrate species. Here we assessed taxonomic and ecological trends in traditional uses of wild edible vertebrates in the country, through an extensive ethnobiological database analysis. Our results showed that at least 165 health conditions are reportedly treated by edible vertebrate species (n=204, mostly fishes and mammals. However, reptiles stand out presenting a higher plasticity in the treatment of multiple health conditions. Considering the 20 disease categories recorded, treatment prescriptions were similar within continental (i.e., terrestrial and freshwater and also within coastal and marine habitats, which may reflect locally related trends in occurrence and use of the medicinal fauna. The comprehension of the multiplicity and trends in the therapeutic uses of Brazilian vertebrates is of particular interest from a conservation perspective, as several threatened species were recorded.

    Full Text Available This paper is an ethnobotanical review of wild edible plants gathered for consumption from the 19th century to the present day, within the present borders of Slovakia. Twenty-four sources (mainly ethnographic documenting the culinary use of wild plants were analysed. The use of 106 species (over 3% of the Slovak flora has been recorded. Nowadays most of them are no longer used, or used rarely, apart from a few species of wild fruits. The most frequently used plants include the fruits of Rubus idaeus, Fragaria spp., Rubus subgenus Rubus, Vaccinium myrtillus, V. vitis-idaea, Fagus sylvatica, Corylus avellana, Prunus spinosa, Pyrus spp., Malus spp., Crataegus spp. and the leaves of Urtica dioica, Rumex acetosa, Chenopodiaceae species, Cardamine amara, Glechoma spp., Taraxacum spp. and Oxalis acetosella. The most commonly used wild food taxa are nearly identical to those used in Poland, and the same negative association of wild vegetables with famine exists in Slovakia, resulting in their near complete disappearance from the present-day diet.

  8. Edible wild plant use in the Faroe Islands and Iceland

    Full Text Available This paper reviews the use of wild edible plants in the Faroe Islands and Iceland from the times of the first settlement of Norse people in the Viking age until today, with a special emphasis on the 18th, 19th and 20th centuries. Animal products have been an important source of nutrients for the islanders of northern Atlantic. Cultivation of cereals on the other hand has played a minor role, and had already been abandoned by late medieval times in Iceland and by the early 20th century on the Faroes. Crops such as potatoes, turnips and other roots were only grown in the small patches of cultivated soil. Wild plants have therefore been of some importance for the Faroese people and the Icelanders; in the last centuries especially for the rural poor and during times of recessions. The native Angelica archangelica L. was gathered in the wild and also cultivated in gardens for centuries. A few species have been part of the regular food staple. Some plants are still gathered and made into food products by small companies, especially in Iceland. In the Faroes, the economic aspect of edible wild plant taxa is mostly of historical interest, although a few products of A. archangelica are sometimes available. Two taxa have been exploited as regular food exclusively in Iceland: Cetraria islandica (L. Arch. and Elymus arenarius L. Icelanders have used C. islandica from the early settlement days and continue to do so today, E. arenarius became obsolete as a food plant a century ago.

    Full Text Available This study explored the rural revitalizing strategy in FAO's Globally Important Agricultural Heritage System (GIAHS site in Noto Peninsula, Ishikawa Prefecture of Japan, using a case study of edible wild plants. This study assessed the current and possible future utilization of edible wild plants as one important NTFP by clarifying the attitudes of consumers and exploring the challenges of harvesting edible wild plants. Traditional ecological knowledge associated with edible wild plants and the related attitudes of consumers towards wild plants was documented. A questionnaire survey found that a majority of the respondents held positive attitude towards edible wild plants as being healthy, safe food, part of traditional dietary culture. Increasing demand of edible wild plants from urban residents aroused conflicts with local residents’ interest given that around 86% of the forested hills are private in Noto Region. Non timber forest products (NTFP extraction can be seen as a tool for creating socioeconomic relationships that are dependent on healthy, biodiverse ecosystems. It was suggested that Japanese Agricultural Cooperatives (JA and Forestry Cooperatives (FCA could be involved with GIAHS process. As important traditional dietary and ecological system, edible wild plants should be a part of GIAHS project for rural revitalization.

    The purpose of the study was to explore sixteen of the most popular edible species of wild-growing mushrooms as potential sources of antioxidants. Among the mushrooms tested, the highest total polyphenol contents, exceeding 100 mg/100 g fresh mass, were found in five mushrooms: Boletus chrysenteron, B. edulis, Leccinum scabrum, L. aurantiacum, and Macrolepiota procera. Antioxidant activity was measured with the FRAP, TEAC, DPPH scavenging ability and ferrous ions chelating ability assays. Results of the study show that wild mushrooms vary according to their antioxidant properties. The highest FRAP potentials, exceeding 1 mmol/100 g, were found in five species ofBoletales: Boletus edulis, B. chrysenteron, Leccinum scabrum, L. aurantiacum, and Suillus grevillei. TEAC values were from 1.07 to 4.01 mmol/100 g fresh mass. High TEAC values (>2.3 mmol/100 g) were found in Leccinum scabrum, L. aurantiacum, Macrolepiota procera, Boletus chrysenteron, and B. edulis. The DPPH radical scavenging effectiveness of mushroom extracts, expressed as EC50 values, was in range 2.91-13.86 mg/mL. Scavenging ability was the highest for B. edulis and B. chrysenteron. The metal chelating ability of mushroom extracts expressed as ECso values of chelating ability on ferrous ions were from 8.02 mg/mL in Cantharellus cibarius to 12.10 mg/mL in Suillus luteus. Among the mushrooms tested, Boletus chrysenteron and B. edulis were characterized by high scores of polyphenol contents and antioxidant activity in the FRAP, TEAC, and DPPH assays. These results place these culinary species of wild-growing mushrooms among products with considerable antioxidant potential.

    Full Text Available This study was designed to document the use and conservation of wild edible plants in Bullen district, northwestern Ethiopia. Data was collected through semistructured interview and focus group discussions. The collected data was analyzed through direct matrix ranking, pairwise ranking, and priority ranking methods. In this study, a total of 77 wild edible plant species were identified. Of these plants, trees account for 35.5% followed by shrubs (31.1%. Fruits were the most harvested parts (59.7% followed by leaves (12.9%, roots and tubers (3.8%, and rhizomes (2.5%. These plants are consumed either raw (57.1% and/or cooked (17%; most are collected by women (62.5% and children (20.8%, but the participation of men is stumpy (4.2%. According to pairwise ranking analysis, fruits of Vitex doniana and the leaves of Portulaca quadrifida are the most preferred plant species because of their sweet taste. However, some of the plants have side effects causing abdominal pain, diarrhea, and constipation. Although religion and cultural norms and values play an important role in the conservation of wild edible plants, population pressure and its associated impacts contributed much to the disappearance of these plants. Thus, community participation is the suggested solution for the conservation and sustainable use of the wild edible plants in the study area.

    Full Text Available Abstract Background A comparative food ethnobotanical study was carried out in fifteen local communities distributed in five districts in the Palestinian Authority, PA (northern West Bank, six of which were located in Nablus, two in Jenin, two in Salfit, three in Qalqilia, and two in Tulkarm. These are among the areas in the PA whose rural inhabitants primarily subsisted on agriculture and therefore still preserve the traditional knowledge on wild edible plants. Methods Data on the use of wild edible plants were collected for one-year period, through informed consent semi-structured interviews with 190 local informants. A semi-quantitative approach was used to document use diversity, and relative importance of each species. Results and discussion The study recorded 100 wild edible plant species, seventy six of which were mentioned by three informants and above and were distributed across 70 genera and 26 families. The most significant species include Majorana syriaca, Foeniculum vulgare, Malvasylvestris, Salvia fruticosa, Cyclamen persicum, Micromeria fruticosa, Arum palaestinum, Trigonella foenum-graecum, Gundelia tournefortii, and Matricaria aurea. All the ten species with the highest mean cultural importance values (mCI, were cited in all five areas. Moreover, most were important in every region. A common cultural background may explain these similarities. One taxon (Majoranasyriaca in particular was found to be among the most quoted species in almost all areas surveyed. CI values, as a measure of traditional botanical knowledge, for edible species in relatively remote and isolated areas (Qalqilia, and Salfit were generally higher than for the same species in other areas. This can be attributed to the fact that local knowledge of wild edible plants and plant gathering are more spread in remote or isolated areas. Conclusion Gathering, processing and consuming wild edible plants are still practiced in all the studied Palestinian areas. About 26

    Locally harvested wild edible plants (WEPs) provide food as well as cash income for indigenous people and are of great importance in ensuring global food security. Some also play a significant role in maintaining the productivity and stability of traditional agro-ecosystems. Shangri-la region of Yunnan Province, SW China, is regarded as a biodiversity hotspot. People living there have accumulated traditional knowledge about plants. However, with economic development, WEPs are threatened and the associated traditional knowledge is in danger of being lost. Therefore, ethnobotanical surveys were conducted throughout this area to investigate and document the wild edible plants traditionally used by local Tibetan people. Twenty-nine villages were selected to carry out the field investigations. Information was collected using direct observation, semi-structured interviews, individual discussions, key informant interviews, focus group discussions, questionnaires and participatory rural appraisal (PRA). Information about 168 wild edible plant species in 116 genera of 62 families was recorded and specimens were collected. Most species were edible greens (80 species) or fruits (78). These WEPs are sources for local people, especially those living in remote rural areas, to obtain mineral elements and vitamins. More than half of the species (70%) have multiple use(s) besides food value. Some are crop wild relatives that could be used for crop improvement. Several also have potential values for further commercial exploitation. However, the utilization of WEPs and related knowledge are eroding rapidly, especially in the areas with convenient transportation and booming tourism. Wild food plants species are abundant and diverse in Shangri-la region. They provide food and nutrients to local people and could also be a source of cash income. However, both WEPs and their associated indigenous knowledge are facing various threats. Thus, conservation and sustainable utilization of these

    The biodiversity rich state of Meghalaya, India located in the realms of mega-biodiversity hotspots, is home to numerous species of wild edible macrofungi that are used extensively by the mycophillic ethnic population, as a part of their traditional cuisine and medicine systems. However, habitat loss, due to deforestation and climate change, is destroying the natural population of these mushrooms, depleting their availability to the local communities. In the present investigation, a GIS guided habitat search, using Lentinula edodes as a representative species, was used in mapping the habitats of wild edible macrofungi of the study region. Sampling of around 4 000 specimens per distinct morphological type available in the traditional markets and “sacred grove” forests indicated presence of ten common genera, belonging to nine different families of wild edible mushrooms. Nutritional profiling of the representative species Lentinula edodes was carried out by evaluation of its moisture, total fat, crude protein and carbohydrates contents by standard methods. Similarly, bioactive components determination was performed by estimation of total phenols, flavonoids, ascorbic acid, β-carotene and lycopenes. Bioactivity of the mushrooms extracts was studied using the DPPH radical scavenging and Human Red Blood Cell (HRBC) membrane stabilization assays. The present investigation successfully attempted to explore remote sensing technologies and GIS (Geographic Information System) based system to predict the natural habitats of wild edible mushrooms of Meghalaya, India which we believe will lead to the generation of a mushroom specific non-wood forest resource mapping system in the near future. Results of nutritional profiling and biological activity studies on the representative species of wild edible mushrooms from the studied region revealed that it is a rich source of essential nutrients and antioxidants.

The plants were collected from areas in the Foggia countryside, and the edible part of each species was analysed for dry matter, protein, cation and anion contents as well as total phenols and antioxidant activities. Among the cations, calcium was the most differentiated among species, ranging 784 mg kg–1 fresh weight (Fw for B. vulgaris to 5886 mg kg–1 Fw for S. hispanicus. The nitrate contents were also highly variable, from 75 mg kg–1 Fw for C. intybus to 3874 mg kg–1 Fw for D. tenuifolia. Total polyphenols ranged from 1054 mg gallic acid equivalents (GAE mg kg–1 Fw for C. solstitialis to 3664 mg GAE mg kg–1 Fw for S. arvensis. Antioxidant activities ranged from 839 mg Trolox equivalents (TE kg–1 Fw for B. vulgaris to 5658 mg TE kg–1 Fw for C. intybus. Significant differences were also noted between wild and cultivated plants in the qualitative parameters. Total polyphenols and antioxidant activity were higher in wild C. intybus and B. officinalis than in their cultivated counterparts. Multivariate analysis (cluster analysis and linear discriminant analysis allowed integration of the ANOVA data to determine the qualitative characteristics of the wild species that contribute most to group differences. The results of the present study aims to improve current knowledge about edible wild species as vegetable sources in the Mediterranean diet.

    Wild edible mushrooms are consumed by the tribes of Meghalaya in the North-Eastern region of India, as part of their ethnic cuisine because of their favored organoleptic characteristics and traditionally known health benefits. Majority of these mushrooms have not yet been characterized in detail and are slowly shrinking in their natural habitats owing to anthropogenic factors and climate change. In the present study, representative specimens of ten morphologically distinct groups of wild edible mushrooms available in the traditional markets and their respective forest habitats, were subjected to multi-loci molecular characterization using SSU, ITS, RPB1 and RPB2 markers. The species identities inferred for the ten mushroom types using the SSU marker matched their morphological description in the case of four morphological groups only whereas the ITS marker successfully resolved the species identity for nine out of the ten mushroom groups under study. Both the protein coding gene markers RPB1 and RPB2 successfully resolved the species identity for three out of the ten morphologically distinct groups. Finally the most likely identity of the wild edible mushrooms under study has been suggested by matching their unique morphological characteristics with the generated DNA barcoding data. The present molecular characterization reveals the ten widely consumed wild mushroom types of Meghalaya, India to be Gomphus floccosus, Lactarius deliciosus, Lactarius volemus, Cantharellus cibarius, Tricholoma viridiolivaceum, Inocybe aff. sphaerospora, Laccaria vinaceoavellanea, Albatrellus ellisii, Ramaria maculatipes and Clavulina cristata. The final species identity generated by the ITS marker matched more accurately with the morphological characteristics/appearance of the specimens indicating the ITS region as a reliable barcode for identifying wild edible mushrooms.

    Kujawska, Monika; Łuczaj, Łukasz

    We studied the cultural significance of wild edible plants for Eastern European migrants who settled in rural subtropical areas of South America. In 50 interviews with Polish migrants and their descendants in northern Misiones, Argentina, we recorded the use of 41 botanical species and two mushroom taxa. Different cultural significance indices were applied and sociodemographic factors such as gender, age and origin were addressed. Out of the ten most salient species, nine were fruits ( Eugenia uniflora , Eugenia involucrata , Rollinia salicifolia , Campomanesia xanthocarpa , Syagrus romanzoffiana , Allophylus edulis , Plinia peruviana , Plinia rivularis , Eugenia pyriformis ) and only one was a green vegetable ( Hypochaeris chillensis ). None of our informants reported famine foods, recreational teas or condiments. Men mentioned more wild edible species than women due to their more extensive knowledge of the forest plants growing further from settlements.

    Full Text Available Turkey has the largest coastal area in the Mediterranean, possesses an extraordinarily rich flora, and a great traditional knowledge. This diversity of plants naturally affects the traditional use of plants and is reflected in the rich Turkish cuisine. Consequently, the Mediterranean Diet (whose typical components are wild greens constitutes one of the important elements of Turkish cuisine. For this reason, the aim of this study was to determine the consumption of wild edible green plants for the Aegean Region of Turkey and to establish the similarities to or differences from consumption in other regions and other cuisine in the Mediterranean Basin. This study compiles and evaluates the ethnobotanical data currently available. There were 111 taxa that were identified as wild edible greens in the study area belonging to 26 different families. Asteraceae (21 taxa were the most commonly consumed as food. It was followed by Boraginaceae with 19 taxa, Apiaceae with 15 taxa and Lamiaceae with 7 taxa, respectively. Rumex and Erodium were the most represented genera with 4 species. Tamus communis and Asparagus acutifolius, Mediterranean elements and distributed in all of the Mediterranean Basin, are among the most widely consumed wild plants in the area. Wild edible plants are consumed in a variety of ways. The most common type of consumption (79 taxa was in salads. The fact that the majority of the plants used in the area are consumed in salads shows the close relationship between the local diet and the concept of the Mediterranean Diet. As a result, very promisingly, there is a renewed or increasing interest in consuming wild food plants as part of this diet.

    Health effects by consuming urban garden products are discussed controversially due to high urban pollution loads. We sampled wild edible mushrooms of different habitats and commercial mushroom cultivars exposed to high traffic areas within Berlin, Germany. We determined the content of cadmium and lead in the fruiting bodies and analysed how the local setting shaped the concentration patterns. EU standards for cultivated mushrooms were exceeded by 86% of the wild mushroom samples for lead and by 54% for cadmium but not by mushroom cultures. We revealed significant differences in trace metal content depending on species, trophic status, habitat and local traffic burden. Higher overall traffic burden increased trace metal content in the biomass of wild mushrooms, whereas cultivated mushrooms exposed to inner city high traffic areas had significantly lower trace metal contents. Based on these we discuss the consequences for the consumption of mushrooms originating from urban areas. - Highlights: • Popular edible mushrooms display large variations in Cd and Pb content. • Low accumulating species are Sparassis crispa, Boletus luridus, or Boletus badius. • High accumulating species are Agaricus ssp., Russula vesca, or Calvatia gigantea. • Cd and Pb content in wild growing edible mushrooms were mostly above EU limits for cultivated mushrooms. • Cd and Pb content in commercial mushrooms cultures were regularly below EU limits for cultivated mushrooms. - Commercial mushroom cultures can be integrated into ‘Edible City’ approaches, but majority of wild growing mushroom samples highly accumulate trace metals

    Full Text Available Nowadays, wild-grown edible mushrooms which are natural, nutritious, and healthy get more and more popular by large consumers. In this paper, UV spectra of different Boletaceae mushrooms with the aid of partial least squares discriminant analysis (PLS-DA and hierarchical cluster analysis (HCA were shown to be a practical and rapid method for discrimination purpose. The specimens of Boletus edulis, Boletus ferrugineus, Boletus tomentipes, Leccinum rugosiceps, and Xerocomus sp. were described based on the UV spectra. From the results, all the specimens were characterized by strong absorption at the wavelengths of 274 and 284 nm and showed the shoulder at 296 nm. However, changes could be seen in the peak heights at the same wavelength for different samples. After analyzing by chemometrics, visual discrimination among samples was presented and the relationships among them were also obtained. This study showed that UV spectroscopy combined with chemometrics methods could be used successfully as a simple and effective approach for characterization of these five wild-grown edible mushrooms at species and genus levels. Meanwhile, this rapid and simple methodology could also provide reference for the discrimination of edible mushrooms.

    Wild edible plants have a tremendous influence on human being even before civilization. These plants contain considerably high nutritional value. Present survey was conducted to explore edible wild vegetables species and their ethnomedicinal uses by the inhabitants of district Harnai, Balochistan, Pakistan. Information was obtained through informed free listing interviews with randomly selected informants and field interviews with key informants selected after free listing. A total of 59 wild edible vegetables belonging to 41 genera, 59 species and 20 plant families are used not only as vegetables and salads but treatment of various diseases The most common plant families in terms of the number of species are the Brassicaceae (10 species), Apiaceae (9 species) and Asteraceae (6 species). The most common parts of the plants used as vegetables and medicine are their leaves (44.45%) and whole plant (22.22%). Plants are often used as decoction (34%), powder (26%). Highest plants species are used for gastrointestinal diseases (45 species). Highest ICF value (0.4) was recorded for dermatological disorders category. 100% fidelity level was found for two plant species i.e., Descurainia sophia, and Caralluma tuberculata. The highest use value was reported for the Lepidium sativum (0.63). Highest RFC value was calculated for Caralluma tuberculata (0.14). Highest use report was calculated for three species Apium graveolens Lepidium sativum and Mentha longifolia, (7 UR for each). The highest FIV was calculated for family Brassicaceae (14 FIV).Our study reveals that plants are still used as a major source of food like vegetables as well as medicine for the local people. Too little or no information is available on their uses, cooking methods and nutritional and physiotherapeutic values. Necessary steps should be taken to perform phytochemical and pharmacological studies to explore the potential nutritional values and herbal drug discovery of such plants. (author)

    An extensive survey for collection and identification of wild edible fungi was undertaken in three districts namely Mandla, Dindori and Shahdol of Northern Hill Region of Chhattisgarh (An Agro-climatic Zone) belonging to Madhya Pradesh. A total of 9 species were documented as wild edible fungi used for food purpose by ethnic tribes of selected region. These wild edible fungi make a substantial contribution to the food security of tribal people of Madhya Pradesh. Identification was done on the basis of morphological characteristics. Termitomyces spp. recorded highest no. of spp. (7) followed by Scleroderma spp (1spp.) and Russula spp. (1spp). For shelf life enhancement, wild edible fungi were irradiated with 0,1.0, 1.5 or 2.0 kGy gamma radiation doses, packed in LDPE bags and stored at 50℃. T. heimii Natrajan showed 15 days, T. radicatus Natarajan 9 days, Scleroderma spp. Showed 24 days of shelf life treated with 1.5 kGy dose whereas Russula Spp., T. eurhizus (Berk) R.heim treated with 1.0 kGy radiation dose showed 9 days of shelf life in terms of all sensory attributes. All the irradiated mushrooms had lower PLW (Physiological Loss in Weight) and better microbial quality as compared to control. Nutritional quality of wild edible fungi was not affected adversely by gamma radiation. This type of study could contribute significantly to improve food security in tribal areas, whose potential as source of nutrition is currently undervalued. (author)

Sing, Volvariella vovacea (Bull. Ex.Fr. Sing. From the proximate analysis, the moisture contents of both wild and cultivated mushrooms ranged from 84.15% fresh weight (FW to 90.21% FW. The ash, crude protein, fat, crude fiber and carbohydrate contents of both wild and cultivated mushrooms were in the dry weight ranges 2.56–13.96%, 11.16–50.29%, 1.43–21.94%, 2.11–38.11% and 9.56–59.73%, respectively, and the contents of macronutrients in the mushrooms varied by variety. Wild mushrooms had a high fiber content compared to cultivated mushrooms. The contents of biologically active compounds of both wild and cultivated mushrooms also varied depending on the variety. Values for the TAC, TPC and TFC of wild mushrooms were higher than those of cultivated mushrooms. In conclusion, the proximate analysis for both wild and cultivated mushrooms was variety dependent and wild mushrooms contained a higher fiber content and more biologically active compounds than cultivated mushrooms.

    2017-08-01

    Full Text Available The article analyzes cultural change related to the consumption of wild edible plants among Chorote Indians from Argentine Chaco, especially the process of construction of prejudices regarding such practices, expressed in the form of symbols of social or religious discredit which has led to their concomitant stigmatization and contempt. The influence of hegemonic agents in the conceptualization of wild edible plants and their utilization practices is here identified and analyzed from observational, exegetical and interpretative points of view. The article specifically discusses if the abandonment of wild edible plant consumption is due to reasons  linked to environmental determinism, to the mere acquisition of new cultural practices, or to socio-religious stigmatization of old food rules among Chorote Indians from Argentine Chaco.

    Highly industrialized and urbanized watersheds may receive various contaminants from anthropogenic activities. In this study, legacy and emerging organohalogenated contaminants (OHCs) were measured in edible wild aquatic organisms sampled from the Pearl River and Dongjiang River in a representative industrial and urban region in China. High concentrations of target contaminants were observed. The Pearl River exhibited higher concentrations of OHCs than the Dongjiang River due to high industrialization and urbanization. Agrochemical inputs remained an important source of OHCs in industrialized and urbanized watershed in China, but vigilance is needed for recent inputs of polychlorinated biphenyls (PCBs) originated from e-waste recycling activities. Bioaccumulation of dichlorodiphenyltrichloroethane and its metabolites (DDTs), hexachlorocyclohexanes (HCHs), PCBs, polybrominated diphenyl ethers (PBDEs), and Dechlorane Plus (DP) was biological species- and compound-specific, which can be largely attributed to metabolic capability for xenobiotics. No health risk was related to the daily intake of DDTs, HCHs, and PBDEs via consumption of wild edible species investigated for local residents. However, the current exposure to PCBs through consuming fish is of potential health concern. Copyright © 2017 Elsevier B.V. All rights reserved.

    Gathering of wild edible plant resources by people in sub-Saharan Africa is discussed with reference to pteridophytes, which is an ancient plant group. Pteridophytes are crucial to food diversity and security in sub-Saharan Africa, although they are notably neglected as a result of inadequate research and agricultural development. Current research and agricultural development agenda still appear to focus on the popular and commonly used food crops, vegetables and fruits; ignoring minor and underutilized plant species such as pteridophytes which have shown significant potential as sources of macro and micro nutrients required to improve the diet of children and other vulnerable groups in sub-Saharan Africa. Documentation of edible pteridophytes is needed to reveal the importance of this plant group in the region and the associated indigenous knowledge about them; so that this knowledge can be preserved and utilized species used to combat dietary deficiencies as well as improve food security in the region. The aim of this study is to present an overview of food value of pteridophytes in sub-Saharan Africa using available literature and to highlight their potential in addressing dietary deficiencies in impoverished communities in the region. This study is based on review of the literature published in scientific journals, books, reports from national, regional and international organizations, theses, conference papers and other grey materials obtained from libraries and electronic search of Google Scholar, ISI Web of Science and Scopus. A total of 24 taxa belonging to 14 genera and 11 families are used in sub-Saharan Africa as fodder and human food. Pteridium aquilinum (L.) Kuhn is the most common edible pteridophyte in sub-Saharan Africa, used as human food in Angola, Cameroon, DRC, Gabon, Madagascar, Nigeria and South Africa, followed by Ophioglossum reticulatum L. (South Africa, Swaziland and Zanzibar), Ceratopteris thalictroides (L.) Brongn. (Madagascar and

    Volatile and semivolatile components of 11 wild edible mushrooms, Suillus bellini, Suillus luteus, Suillus granulatus, Tricholomopsis rutilans, Hygrophorus agathosmus, Amanita rubescens, Russula cyanoxantha, Boletus edulis, Tricholoma equestre, Fistulina hepatica, and Cantharellus cibarius, were determined by headspace solid-phase microextraction (HS-SPME) and by liquid extraction combined with gas chromatography-mass spectrometry (GC-MS). Fifty volatiles and nonvolatiles components were formally identified and 13 others were tentatively identified. Using sensorial analysis, the descriptors "mushroomlike", "farm-feed", "floral", "honeylike", "hay-herb", and "nutty" were obtained. A correlation between sensory descriptors and volatiles was observed by applying multivariate analysis (principal component analysis and agglomerative hierarchic cluster analysis) to the sensorial and chemical data. The studied edible mushrooms can be divided in three groups. One of them is rich in C8 derivatives, such as 3-octanol, 1-octen-3-ol, trans-2-octen-1-ol, 3-octanone, and 1-octen-3-one; another one is rich in terpenic volatile compounds; and the last one is rich in methional. The presence and contents of these compounds give a considerable contribution to the sensory characteristics of the analyzed species.

    The organic acids and phenolics compositions of nine wild edible mushrooms species (Suillus bellini, Tricholomopsis rutilans, Hygrophorus agathosmus, Amanita rubescens, Russula cyanoxantha, Boletus edulis, Tricholoma equestre, Suillus luteus, and Suillus granulatus) were determined by HPLC-UV and HPLC-DAD, respectively. The antioxidant potential of these species was also assessed by using the DPPH* scavenging assay. The results showed that all of the species presented a profile composed of at least five organic acids: oxalic, citric, malic, quinic, and fumaric acids. In a general way, the pair of malic plus quinic acids were the major compounds. Only very small amounts of two phenolic compounds were found in some of the analyzed species: p-hydroxybenzoic acid (in A. rubescens, R. cyanoxantha, and T. equestre) and quercetin (in S. luteus and S. granulatus). All of the species exhibited a concentration-dependent scavenging ability against DPPH*. T. rutilans revealed the highest antioxidant capacity.

    The anti oxidative activity of the 80% ethanol extract obtained from eleven commonly consumed wild edible plants was determined according to the phospho molybdenum method, reducing power, metal chelating, superoxide anion and free radical scavenging activity and compared to standard compounds such as butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT) and trolox. Total phenolic compounds, flavonoids, and anthocyanins in the extracts were also measured. Trachystemon orientalis, Vaccinium mrytillus, Rumex acetosella Polygonum amphibium, Beta vulgaris, and Similax Excelsa had the highest antioxidant capacities. Overall results showed that these plants can serve as good sources of bioactive polyphenols in the human diet and can be regarded as good candidates for nutritional supplement formulations due to their high concentrations of total phenolic compounds, flavonoids and anthocyanins as well as their strong antioxidant activity.

    Full Text Available Thirteen popular wild edible mushroom species in Yunnan Province, Boletus bicolor, Boletus speciosus, Boletus sinicus, Boletus craspedius, Boletus griseus, Boletus ornatipes, Xerocomus, Suillus placidus, Boletinus pinetorus, Tricholoma terreum, Tricholomopsis lividipileata, Termitomyces microcarpus, and Amanita hemibapha, were analyzed for their free amino acid compositions by online pre-column derivazation reversed phase high-performance liquid chromatography (RP-HPLC analysis. Twenty free amino acids, aspartic acid, glutamic acid, serine, glycine, alanine, praline, cysteine, valine, methionine, phenylalanine, isoleucine, leucine, lysine, histidine, threonine, asparagines, glutamine, arginine, tyrosine, and tryptophan, were determined. The total free amino acid (TAA contents ranged from 1462.6 mg/100 g in B. craspedius to 13,106.2 mg/100 g in T. microcarpus. The different species showed distinct free amino acid profiles. The ratio of total essential amino acids (EAA to TAA was 0.13–0.41. All of the analyzed species showed high contents of hydrophobic amino acids, at 33%–54% of TAA. Alanine, cysteine, glutamine, and glutamic acid were among the most abundant amino acids present in all species. The results showed that the analyzed mushrooms possessed significant free amino acid contents, which may be important compounds contributing to the typical mushroom taste, nutritional value, and potent antioxidant properties of these wild edible mushrooms. Furthermore, the principal component analysis (PCA showed that the accumulative variance contribution rate of the first four principal components reached 94.39%. Cluster analysis revealed EAA composition and content might be an important parameter to separate the mushroom species, and T. microcarpus and A. hemibapha showed remarkable EAA content among the 13 species.

    Full Text Available Abstract Background Wild edible plants (WEP provide staple and supplement foods, as well as cash income to local communities, thus favouring food security. However, WEP are largely ignored in land use planning and implementation, economic development, and biodiversity conservation. Moreover, WEP-related traditional knowledge is rapidly eroding. Therefore, we designed this study to fulfill a part of the knowledge gap by providing data on diversity, traditional knowledge, economic potential, and conservation value of WEP from Nepal. Methods The information was collected through focus group discussions and key informant interviews. Percentage of general utility of the plants among the study communities was evaluated using the Chi-square (χ2 test of homogeneity. High priority species were identified after consultation with the local stakeholders followed by scoring based on defined criteria. Pairwise ranking was used to assess ethnoecological knowledge to identify the threats to WEP. Results We documented 81 species belonging to Angiosperms (74, Pteridophytes (5, and Fungi (2. Most of the species were used as fruits (44 species followed by vegetables (36. Almost half of the species (47% were also used for purposes other than food. From the species with market value (37% of the total, 10 were identified as high priority species. Pairwise ranking revealed that WEP are threatened mostly by habitat destruction, land-use change and over-harvesting. Some of these plants are crop wild relatives and could thus be used for crop improvement. Interestingly, our study also revealed that young people who spend most of the time in the forest as herdsmen are particularly knowledgeable of wild fruit plants. Conclusion We provide empirical evidence from a relatively large area of Nepal about diversity and status of WEP, as well as methodological insights about the proper knowledge holders to consult. Regarding the unique and important knowledge they have on WEP

    An increasing interest in snail farming in Greece and other European countries has been observed. Despite the fact that edible snails have been involved with problems of Salmonella spp. contamination, there are to our knowledge only limited studies regarding microbiological safety and hygiene of such products. Enumeration of microbial populations and presence/absence of Salmonella spp. in snail meat and intestines of wild Cornu aspersum, Helix lucorum and cultured Cornu aspersum snails from indoor/outdoor type farms was conducted. Furthermore, snail-processing steps were simulated in the laboratory and the population reduction in snail meat was determined. Microbial populations were higher in intestines than snail meat in almost all cases. Escherichia coli/coliforms and Enterococcus spp. populations were lower in the intestines and snail meat of cultured C. aspersum. Salmonella spp. were detected in the intestines and snail meat of wild snails only. The high levels of bacterial populations were considerably reduced after the appropriate processing. The lower populations of E. coli/coliforms, Enterococcus spp. and especially the absence of Salmonella spp. in cultured snails show that the controlled conditions decrease the possibility of pathogen presence and contribute to food safety and public health. © 2013 Society of Chemical Industry.

    This study aimed to determine the contents of main mineral elements of wild Boletus edulis and to assess its edible safety, which may provide scientific evidence for the utilization of this species. Fourteen mineral contents (Ba, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Na, Ni, Sr, V and Zn) in the caps and stipes of B. edulis as well as the corresponding surface soils collected from nine different geographic regions in Yunnan Province, southwest China were determined. The analyses were performed using inductively coupled plasma atomic emission spectrometer (ICP-AES) after microwave digestion. Measurement data were analyzed using variance and Pearson correlation analysis. Edible safety was evaluated according to the provisionally tolerable weekly intake (PTWI) of heavy metals recommended by United Nations Food and Agriculture Organization and World Health Organization (FAO/WHO). Mineral contents were significantly different with the variance of collection areas. B. edulis showed relative abundant contents of Ca, Fe, Mg and Na, followed by Ba, Cr, Cu, Mn and Zn, and the elements with the lower content less were Cd, Co, Ni, Sr and V. The elements accumulation differed significantly in caps and stipes. Among them, Cd and Zn were bioconcentrated (BCF > 1) while others were bioexcluded (BCF < 1). The mineral contents in B. edulis and its surface soil were positively related, indicating that the elements accumulation level was related to soil background. In addition, from the perspective of food safety, if an adult (60 kg) eats 300 g fresh B. edulis per week, the intake of Cd in most of tested mushrooms were lower than PTWI value whereas the Cd intakes in some other samples were higher than this standard. The results indicated that the main mineral contents in B. edulis were significantly different with respect to geographical distribution, and the Cd intake in a few of regions was higher than the acceptable intakes with a potential risk.

    Full Text Available Public demand for harvesting wild edible mushrooms has risen in recent decades and currently affects many forested areas around the world. The idea of introducing permits for users has been conceived as a tool for ecosystem management. The problem is that policy-makers lack the necessary means to help guide them when establishing prices for such harvesting permits. Valuing the recreational benefits which mushroom harvesters derive from harvesting wild edible mushrooms may provide certain guidelines as to how much people would be willing to pay and may also justify future payments levied on harvesters. The aim of the present article is to estimate a model for determining citizens’ willingness to pay for a harvesting permit in a forest in Andalusia (Spain using contingent valuation methods. Results show that mean willingness to pay is 22.61 Euros (USD28.18 per harvester and season. This amount depends on several socioeconomic factors and preferences related to harvesters’ experiences.

    This paper discusses activity concentrations of 210 Po, 210 Pb, 40 K and 137 Cs in edible wild berries and mushrooms collected from Øvre Dividalen national park, Northern Norway and derives committed effective ingestion doses to man based on high consumption rates of these wild foods. Edible wild berries and mushrooms accumulated similar levels of 210 Pb, but mushrooms accumulated higher levels of 210 Po and 40 K than berries. There appears to be a clear difference in the ability of Leccinum spp. of fungi to accumulate 210 Po and/or translocate 210 Po to mushrooms compared to Russula spp. of fungi. Activity concentrations of 137 Cs in edible wild berries and mushrooms from Øvre Dividalen national park reflected the lower levels of fallout of this radionuclide in Northern Norway compared to more central areas following the Chernobyl accident. For mushrooms, ingestion doses are dominated by 210 Po, while for berries, 40 K is typically the main contributor to dose. Based on high consumption rates, ingestion doses arising from the combination of 210 Po, 210 Pb and 40 K were up to 0.05 mSv/a for berries and 0.50 mSv/a for mushrooms. Consumption of such wild foods may result in a significant contribution to total annual doses when consumed in large quantities, particularly when selecting mushrooms species that accumulate high activity concentrations of 210 Po. - Highlights: ► 210 Po/ 210 Pb activity ratios were typically less than one for berries. ► 210 Po/ 210 Pb activity ratios were all greater than one for mushrooms. ► Dose rates from mushrooms were dominated by 210 Po and by 40 K for berries. ► Wild foods can give a significant contribution to total annual ingestion dose.

    In this study 6 species of wild edible mushrooms were evaluated in terms of their total phenolic content and antioxidant activity using 1,1-diphenyl-2-picrylhydrazyl radical and ferric reducing antioxidant power assay methods. The mushrooms, namely Armillaria mellea, Cantharellus cibarius, Lactarius deliciosus, Leccinum aurantiacum, Suillus luteus, and Boletus badius, were dried using both freeze drying and convection drying at 50°C. The amounts of phenolic compounds varied from 3.0 ± 0.1 to 12.8 ± 0.4 mg gallic acid equivalents/g dry weight (for water extracts) and from 2.4 ± 0.1 to 11 ± 0.5 mg gallic acid equivalents/g dry weight (for ethanolic extracts). The species that presented the highest antioxidant potential were B. badius and S. luteus. The impact of hot-air drying on the antioxidant activity of water and ethanolic extracts was evaluated. We demonstrated that hot-air drying may have either a negative or positive influence on phenolics and antioxidant activity, depending on the mushroom species. However, a negative effect was more frequent.

    A comparative study on the amino acid composition of 11 wild edible mushroom species (Suillus bellini, Suillus luteus, Suillus granulatus, Tricholomopsis rutilans, Hygrophorus agathosmus, Amanita rubescens, Russula cyanoxantha, Boletus edulis, Tricholoma equestre, Fistulina hepatica, and Cantharellus cibarius) was developed. To define the qualitative and quantitative profiles, a derivatization procedure with dabsyl chloride was performed, followed by HPLC-UV-vis analysis. Twenty free amino acids (aspartic acid, glutamic acid, asparagine, glutamine, serine, threonine, glycine, alanine, valine, proline, arginine, isoleucine, leucine, tryptophan, phenylalanine, cysteine, ornithine, lysine, histidine, and tyrosine) were determined. B. edulis and T. equestre were revealed to be the most nutritional species, whereas F. hepatica was the poorest. The different species exhibited distinct free amino acid profiles. The quantification of the identified compounds indicated that, in a general way, alanine was the major amino acid. The results show that the analyzed mushroom species possess moderate amino acid contents, which may be relevant from a nutritional point of view because these compounds are indispensable for human health. A combination of different mushroom species in the diet would offer good amounts of amino acids and a great diversity of palatable sensations.

    Olive tree is the first botanical noted in the Bible. Leaves and fruits of olive are rich sources of Phenols, triterpenes, and flavanoids. Oleuropein obtained from the leaves extract is believed to be important therapeutic compound. Olive leaf and oils are used for the treatment of different diseases as folklore medicines by different ethnic groups in different countries of the world. The present study aims to investigate the potential antimicrobial activities of wild (Olea ferruginea) and edible (Olea europaea) olive leaf crude extracts, crude oils from ripe and unripe fruits and extra virgin oils against the selected gram positive and gram negative bacterial strains. The results show that olive leaf and oil have potential antibacterial activities against some of the gram positive and gram negative bacterial strains. However, certain strains were resistant to the extracts. It was also found that the activities were higher for the gram negative strains as compared to gram positive strains. The methanolic and ethanolic extracts were found to be more efficient in extraction than the other solvents used. Leaf extracts were more effective than the oil extracted from ripe and unripe fruits. There was no significant difference in the activities of extra virgin oils and crude leaf extracts. From the results it is concluded that the leaf extract is a cheap and effective antibacterial agent that can be used as alternative to purified oil. (author)

    Full Text Available Wild plants in forests provide valuable living resources for rural communities. The location where local people harvest various species is important to the wise use of forest ecosystem services. Using global positioning system (GPS tracking of harvesters’ activities as well as geographic information system (GIS and a generalized linear model (GLM, this study analyzed the spatial differences among harvesting sites of three popular edible ferns, i.e., ostrich fern (Matteuccia struthiopteris, bracken (Pteridium aquilinum, and royal fern (Osmunda japonica, in mountainous villages of Northeastern Japan. The explanatory variables used were vegetation classes, terrain features, and proximity to roadways. The GLM yielded clear differences in harvesting sites among species that were affected by both the species’ ecological characteristics and human behavior. Ostrich fern was harvested mainly in canopy openings along valley floors, whereas royal fern harvest sites were frequently located in snow avalanche scrublands. Bracken was mainly harvested in deforested areas or young conifer plantations. Whereas ostrich fern and bracken harvest sites were restricted by the accessibility from roadways, this was not the case for royal fern. Potential harvest sites of ferns were estimated with the highest value for bracken. Our results suggest that local harvesters seriously consider various natural and anthropogenic factors to maintain effective and sustainable harvesting.

    The genus Ficus, collectively known as figs, is a key component of tropical forests and is well known for its ethnobotanical importance. In recent decades an increasing number of studies have shown the indigenous knowledge about wild edible Ficus species and their culinary or medicinal value. However, rather little is known about the role of these species in rural livelihoods, because of both species and cultural diversity. In this study we 1) collected the species and ethnic names of wild edible Ficus exploited by four cultural groups in Xishuangbanna, Southwest China, and 2) recorded the collection activities and modes of consumption through semi-structured interviews, 3) investigated the resource management by a statistical survey of their field distribution and cultivation, and 4) compared and estimated the usage intensities by the grading method. The young leaves, leaf buds and young or ripe syconia of 13 Ficus species or varieties are traditionally consumed. All the species had fixed and usually food-related ethnic names. All four cultural groups are experienced in the collection and use of edible Ficus species as vegetables, fruits or beverages, with the surplus sold for cash income. Different cultural groups use the Ficus species at different intensities because of differences in availability, forest dependency and cultural factors. Both the mountain and basin villagers make an effort to realize sustainable collection and meet their own and market needs by resource management in situ or cultivation. In comparison with reports from other parts of the world, ethnic groups in Xishuangbanna exploited more edible Ficus species for young leaves or leaf buds. Most of the edible species undergo a gradient of management intensities following a gradient of manipulation from simple field gathering to ex situ cultivation. This study contributes to our understanding of the origins and diffusion of the knowledge of perception, application and managing a group of

    Large quantities of radionuclides were released from the accident of the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) in March 2011 and farmlands and forests in Fukushima Prefecture were contaminated.The most significant radionuclides related to the contamination of vegetation are {sup 134}Cs (half-life: 2 y) and {sup 137}Cs (half-life: 30 y).Concentrations of radiocesium in vegetables and rice decreased over time to values markedly lower than the guideline (100 Bq/kg). However, radiocesium concentrations in some edible wild plants and mushrooms have still shown very high level. Therefore, it is important to identify plants which accumulate cesium and to clarify the transfer mechanism of radiocesium. In this study, we analyzed both radiocesium and stable cesium in edible wild plants (Sansai) collected from forests in Fukushima Prefecture. Possible mechanisms of high radiocesium transfer into the plants in forest ecosystems were considered. Wild plants were collected from forests in Iitate-mura, Fukushima Prefecture, in 2012 and 2013. We have focused on Koshiabura (Acanthopanaxsciadophylloides) a plant related to Araliaceae and collected their leaves from four different trees in May and July 2013.Radiocesium ({sup 134}Cs and {sup 137}Cs) concentrations were measured with a Ge-detector. For elemental analysis, the samples were freeze-dried and milled with a mixer. Powdered samples (0.1 g) were digested in teflon vessels with an acid mixture (HNO{sub 3}, HF and HClO{sub 4}) on a hot plate. After digestion, each sample was evaporated to dryness. Then, the sample residue was dissolved in 2% HNO{sub 3}. The concentrations of major and minor elements were determined by ICP-MS. Leaves of Koshiabura showed very high radiocesium concentrations up to 60,000 Bq/kg on a dry weight basis, or 10,000 Bq/kg on a wet weight basis.Root uptake and translocation of radiocesium from other parts of the plants to the leaves were expected to occur. Koshiabura plants tend to be shallowly

    Clerodendrum viscosum , Eryngium foetidum , Lippia javanica , and Murraya koenigii are one among the common wild edible plants in Northeast India which are also used as antidiabetic, stomach-ache relieving drugs, etc., The present study was aimed to reveal the phytochemical, antioxidant, and anthelmintic activity of the plants. The antioxidant capacity of methanolic extract of plants was studied by 1,1-diphenyl-2-picrylhydrazyl (DPPH), ferric reducing antioxidant power, TBARS, and total antioxidant activity (TAA). Total phenolics, flavonoids, Vitamin C, carbohydrate, and protein are also estimated following standard protocols. Anthelmintic activity of the extracts has also been studied in vitro against trematode parasites. The result showed that the methanolic extracts of plants possess a substantial quantity of alkaloids, phenolics, flavonoids, proteins, carbohydrates, and Vitamin C. Phenolics, flavonoids, and Vitamin C contents were found higher in C. viscosum followed by M. koenigii , L. javanica , and E. foetidum . The in vitro antioxidant assays revealed substantial free radical scavenging property in all the plants. TAA increased in the order C. viscosum > M. koenigii > L. javanica > E. foetidum . Similarly, C. viscosum displayed a better antioxidant capacity with IC 50 values 29.74 ± 3.63 μg and 148.77 ± 18.38 μg for DPPH and thiobarbituric acid reactive species, respectively. In addition, the plant extracts also showed good anthelmintic activity against Paramphistomum sp. Time taken for paralysis and death were 0:56 ± 0:09 h and 1:35 ± 0:07 h for L. javanica at 50 mg/mL concentration. The study therefore suggests the importance of tested plants as a natural source of free radical scavenger and plausible veterinary uses.

    The metal (Cu, Ni, Cd, Hg, As, Pb) contents in wild edible mushrooms collected from three different sites in China were determined by atomic absorption spectrometry and atomic fluorescence spectrometry. All element concentrations were determined on a dry weight basis. A total of 11 species was studied, five being from the urban area and six from rural areas in China. The As content ranged from 0.44 to 1.48 mg/kg. The highest As content was seen in Macrolepiota crustosa from the urban area, and the lowest in Russula virescens from rural areas. A high Ni concentration (1.35 mg/kg) was found in Calvatia craniiformis from the urban area. The lowest Ni level was 0.11 mg/kg, for the species R. virescens and Cantharellus cibarius. The Cu content ranged from 39.0 to 181.5 mg/kg. The highest Cu content was seen in Agaricus silvaticus and the lowest in C. cibarius. The Pb content ranged from 1.9 to 10.8 mg/kg. The highest Pb value was found in C. craniiformis. The Cd content ranged from 0.4 to 91.8 mg/kg. The highest Cd value was found in M. crustosa. The Hg content ranged from 0.28 to 3.92 mg/kg. The highest Hg level was found in Agaricus species. The levels of the heavy metals Cd, Pb, and Hg in the studied mushroom species from urban area can be considered high. The metal-to-metal correlation analysis supported they were the same source of contamination. High automobile traffic was identified as the most likely source of the contamination. Based upon the present safety standards, consumption of those mushrooms that grow in the polluted urban area should be avoided.

    Full Text Available The antioxidative activity of the 80% ethanol extract obtained from eleven commonly consumed wild edible plants was determined according to the phosphomolybdenum method, reducing power, metal chelating, superoxide anion and free radical scavenging activity and compared to standard compounds such as butylated hydroxyanisole (BHA, butylated hydroxytoluene (BHT and trolox. Total phenolic compounds, flavonoids, and anthocyanins in the extracts were also measured. Trachystemon orientalis, Vaccinium mrytillus, Rumex acetosella Polygonum amphibium, Beta vulgaris, and Similax Excelsa had the highest antioxidant capacities. Overall results showed that these plants can serve as good sources of bioactive polyphenols in the human diet and can be regarded as good candidates for nutritional supplement formulations due to their high concentrations of total phenolic compounds, flavonoids and anthocyanins as well as their strong antioxidant activity.La actividad antioxidante de extractos etanólicos al 80%, obtenidos de once plantas salvajes comúnmente consumidas, fue determinada por el método del fosfomolibdeno, poder reductor, actividad quelatante de metales, actividad captadora de aniones superóxidos y actividad captadora de radicales libres, y comparada con compuestos patrones tales como el butil hidroxianisol (BHA, butil hidroxitolueno (BHT y Trolox. El contenido de fenoles totales, flavonoides y antocianinas en el extracto fue también determinado. Trachystemon orientalis, Vaccinium mrytillus, Rumex acetosella Polygonum amphibium, Beta vulgaris, y Similax Excelsa tienen las capacidades antioxidantes más altas. En general, los resultados muestran que estas plantas pueden servir como una buena fuente de polifenoles bioactivos en la dieta humana, y pueden ser considerados como buenos candidatos para su uso como suplemento nutricional en formulaciones debido a su alta concentración en fenoles, flavonoides y antocinainas y a su fuerte actividad

    Full Text Available In the present paper, we focused on assessment of the contamination levels of five species (n = 33 of edible wild mushrooms (Macrolepiota procera, Boletus reticulatus, Suillus grevillei, Russula xerampelina and Xerocomellus chrysenteron. We collected samples of above-ground parts of the macroscopic fungi species in historical mining and processing area surrounding Banská Bystrica (Central Slovakia in 2014. Within 2 m radius of the samples, we also took samples of underlying substrate. On the basis of the substrate, along with the monitored contaminant – mercury, we calculated bioaccumulation factors for individual species and their anatomical parts (cap and stipe. From the obtained results of the mercury content in the edible mushrooms, we then determined provisionally tolerable weekly intake (PTWI. The limit value for mercury (0.350 mg Hg kg-1 for an individual with average weight of 70 kg is defined by the World Health Organization (WHO. Our results suggest that despite the relatively low level of Hg in the underlying substrate, the species Macrolepiota procera (1.98 mg kg-1 ± 68.2 (0.41 - 3.20 mg kg-1 DW is characterized by extremely high bioaccumulation ability, as confirmed by the bioaccumulation factors (BAFc = 15.3; BAFs = 8.02. PTWI value was exceeded by almost 20%. In case of the other studied edible wild mushroom species, we did not record any increased risk of mercury intake by consumers. Generally it can be stated that consumption of wild mushrooms represents a relatively small but significant risk of negative impact on the consumer´s health.

    Full Text Available Kawauchi Village, in Fukushima Prefecture, is located within a 30-km radius of the nuclear disaster site of the Fukushima Daiichi Nuclear Power Plant (FDNPP. "Sansai" (edible wild plants in this village have been evaluated by gamma spectrometry after the residents had returned to their homes, to determine the residents' risk of internal exposure to artificial radionuclides due to consumption of these plants. The concentrations of radiocesium (cesium-134 and cesium-137 were measured in all 364 samples collected in spring 2015. Overall, 34 (9.3% samples exceeded the regulatory limit of 100 Bq/kg established by Japanese guidelines, 80 (22.0% samples registered between 100 Bq/kg and 20 Bq/kg, and 250 (68.7% registered below 20 Bq/kg (the detection limit. The internal effective doses from edible wild plants were sufficiently low (less than 1 mSv/y, at 3.5±1.2 μSv/y for males and 3.2±0.9 μSv/y for females (2.7±1.5 μSv/y for children and 3.7±0.7 μSv/y for adults in 2015. Thus, the potential internal exposure doses due to consumption of these edible wild plants were below the applicable radiological standard limits for foods. However, high radiocesium levels were confirmed in specific species, such as Eleutherococcus sciadophylloides ("Koshiabura" and Osmunda japonica (Asian royal fern, "Zenmai". Consequently, a need still might exist for long-term follow-up such as environmental monitoring, physical and mental support to avoid unnecessary radiation exposure and to remove anxiety about adverse health effects due to radiation. The customs of residents, especially the "satoyama" (countryside culture of ingesting "sansai," also require consideration in the further reconstruction of areas such as Kawauchi Village that were affected by the nuclear disaster.

    Local people in the Himalayan region use a wide range of wild and non-cultivated edible plants (WNEPs) for food, spice, medicinal, and cultural purposes. However, their availability, use, status and contribution to livelihood security are poorly documented, and they have been generally overlooked in recent agro-biodiversity conservation and management programmes. The study aimed to investigate WNEP diversity and current status in a part of the Kailash Sacred Landscape-a transboundary landscape shared by Nepal, India and PR China-in terms of collection, use, management and conservation initiatives. Multiple methodologies and tools were used for data collection. A series of participatory tools (45 key informant interviews, 10 focus group discussions, a crop diversity fair, direct observation of species through a transect walk and rapid market assessments) was followed by a household survey (195 respondents) and complemented by a literature review. The study recorded 99 WNEPs belonging to 59 families of which 96 were angiosperms, one gymnosperm and two pteridophytes. Species were used for food, spice, medicine, rituals and income generation. Thirty-five species had multiple uses, including these: 40 species were used for fruit and 31 for vegetables. WNEPs contribute significantly to daily food requirements, especially the vegetables. The use value of Dryopteris cochleata was found highest (0.98) among frequently used vegetable species. The values of informant consensus factor were found maximum for worms in the stomach (0.99) and minimum for skin disease treatment (0.67). Nearly 85% of households depended exclusively on WNEPs for at least more than a month per year. Results on the importance and use of different species, gender roles in WNEP activities and conservation approaches are presented. People living in the Kailash Sacred Landscape depend significantly on WNEPs, and this is especially critical in times of food shortage. The WNEPs have considerable potential as

    Full Text Available Abstract Background We compare traditional knowledge and use of wild edible plants in six rural regions of the northwest of the Iberian Peninsula as follows: Campoo, Picos de Europa, Piloña, Sanabria and Caurel in Spain and Parque Natural de Montesinho in Portugal. Methods Data on the use of 97 species were collected through informed consent semi-structured interviews with local informants. A semi-quantitative approach was used to document the relative importance of each species and to indicate differences in selection criteria for consuming wild food species in the regions studied. Results and discussion The most significant species include many wild berries and nuts (e.g. Castanea sativa, Rubus ulmifolius, Fragaria vesca and the most popular species in each food-category (e.g. fruits or herbs used to prepare liqueurs such as Prunus spinosa, vegetables such as Rumex acetosa, condiments such as Origanum vulgare, or plants used to prepare herbal teas such as Chamaemelum nobile. The most important species in the study area as a whole are consumed at five or all six of the survey sites. Conclusion Social, economic and cultural factors, such as poor communications, fads and direct contact with nature in everyday life should be taken into account in determining why some wild foods and traditional vegetables have been consumed, but others not. They may be even more important than biological factors such as richness and abundance of wild edible flora. Although most are no longer consumed, demand is growing for those regarded as local specialties that reflect regional identity.

    There is little information available on the factors influencing people's selection of wild plants for consumption. Studies suggest a suitable method of understanding the selection of edible plants is to assess people's perceptions of these resources. The use and knowledge of wild resources is disappearing, as is the opportunity to use them. This study analyzes people's perceptions of native wild edible plants in a rural Caatinga (seasonal dry forest) community in Northeast Brazil and the relationships between the use of these resources and socioeconomic factors. Semi-structured interviews with 39 people were conducted to form a convenience sample to gather information regarding people's perceptions of 12 native wild edible plant species. The relationships between variables were assessed by simple linear regression analysis, Pearson and Spearman correlation analyses, and in the case of nominal variables, contingency tables. The discourse of participants regarding their opinions of the use of wild plants as food was analyzed through the collective subject discourse analysis technique. Perceptions were classified into 18 categories. The most cited category was organoleptic characteristics of the edible part; more specifically, flavor. Flavor was the main positive perception associated with plant use, whereas the negative perception that most limited the use of these plants was cultural acceptance. Perceptions of the use of wild edible plants were directly correlated with both interviewee age and income. Within the studied community, people's perceptions of native wild edible plants are related to their consumption. Moreover, the study found that young people have less interest in these resources. These findings suggest that changing perceptions may affect the conservation of plants, traditional practices and the associated knowledge.

    Full Text Available The edible mushrooms Verpa bohemica and Morchella esculenta are locally used for dietary and antioxidant in tribal areas of Kashmir Himalaya. In the present study, sequences of solvents on the basis of their polarity were used for the extraction from selected mushrooms. The comprehensive antioxidant activity of all edible mushroom extracts was evaluated by seven different methods. V. bohemica exhibited significant inhibitory activity of radicals among all the mushrooms while Morchella extracts protected the DNA damage from OH· radicals. This study provides us the substantiation for the use of these mushrooms as antioxidants besides being already eaten as food.

    Full Text Available The aim of the study was to investigate knowledge and use of wild food plants and fungi in Han (i.e. Chinese nationality villages in central China, including famine plants used in the respondents' childhood. A valley adjacent to the extremely species-rich temperate forest vegetation of the Taibai Nature Reserve was chosen. Eighty-two people from 5 villages took part in the study. Altogether, 159 wild food plant species and 13 fungi folk taxa were mentioned by informants. The mean number of freelisted wild foods was very high (24.8; median – 21.5. An average respondent listed many species of wild vegetables (mean – 17, me- dian – 14.5, a few wild fruits (mean – 5.9 and median – 6 and very few fungi (mean – 1.9, median – 1, which they had eaten. Over 50% of respondents mentioned gathering the young shoots or leaves of Celastrus orbiculatus, Staphylea bumalda and S. holocapra, Caryopteris divaricata, Helwingia japonica, Pteridium aquilinum, Pimpinella sp., Amaranthus spp., Matteucia struthiopteris, Allium spp., Cardamine macrophylla and Chenopodium album. Only one species of fruits (Schisandra sphenanthera and none of the mushrooms were mentioned by over half of the respondents. Although very diverse, it can be noted that the use of wild vegetables has decreased compared to the second half of the 20th century, as informants listed several plants which they had stopped using (e.g. Abelia engleriana due to the availability of cultivated vegetables and other foodstuffs. On the other hand, the collection of the most well-known wild vegetables is maintained by selling them to tourists visiting agritourist farms, and restaurants.

    Thirteen species of wild edible plants belonging to 11 botanical families consumed in the traditional Mediterranean diet were evaluated. Sanguisorba minor, Quercus ballota and Sedum sediforme showed the highest hydrophilic total antioxidant activity (H-TAA) and total phenols. Asparagus acutifolius, Allium ampeloprasum, Foeniculum vulgare and Malva sylvestris presented high levels of potassium, Malva and Asparagus are interesting due to their zinc content, and Urtica urens contains a high content of calcium. Sensory analysis indicated that fruits from Q. ballota could be considered very sweet and plants of Crithmum maritimum and Oxalis pes-caprae are very acidic. Moreover, testers highlighted the salty taste of C. maritimum. Mesembryanthemum nodiflorum and Mesembryanthemum cristalinum, the spicy taste of A. ampeloprasum, and the aroma of F. vulgare. Our results indicate that increased consumption of the investigated plant species could provide health benefits. Moreover, due to their sensorial properties, they could be used as new ingredients to improve the diversity in modern diet and highly creative cuisine.

    From time immemorial, wild plants have been used for edible purposes. They still continue to be a major source of nutrition for tribal people. However, unfortunately, their use is now declining. This has implications in food security, narrowing genetic base, and future leads. The present study was, therefore, carried out in Chhota Bhangal region of Western Himalaya to analyze uses of wild edible plants (WEP) and the motivations behind their use or abandonment. Field surveys were conducted to the study area from January 2016 to March 2017. Household surveys, group discussions, free listing, and structured questionnaires were used to elicit information on WEP. WEP use was categorized into six categories (vegetables, fruits, chutney, flavoring food, raw food, and local brew). Trends of use (continuing, decreasing, increasing, and not used) and motivations (environmental, economic, sociocultural, agriculture and land use practices, and human-wildlife conflict) behind their use were analyzed. Fifty plant species were used by the local people for edible purposes under six WEP categories. Mean and median of WEP used per respondent was 22.3 and 21, respectively. Highest number of these were used as vegetable (mean 8.9) while lowest were used as brew (mean 0.4). Out of the 50 WEP used, 20 were prioritized for motivation analyses. Though plant use is still maintained in the area, changes are evident. Almost 50% of the respondents revealed that they still continue the use of WEP while 36% reported trends of declining use as compared to 5-10 years back. Close to 10% respondents have stopped consuming WEP now and ~ 3% reported an increase in the use of WEP. Among the WEP categories, use of chutney showed an increasing trend. Sociocultural motivations were found to play a prime role, both, in limiting and promoting WEP use. Taste and aroma were the major sociocultural reasons behind using WEP while modernization and changing lifestyle were the main reasons behind declining

    There are 20 species of the Berberidaceae family described in Chile, whose fruits are edible and show high anthocyanin and hydroxycinnamic acid levels. Berberis microphylla G. Forst, commonly known as calafate, is the most extensively distributed. Flavonols and alkaloids in seed, pulp, skin, and whole calafate berry extracts and other Berberis were studied using HPLC-DAD-ESI-MS/MS and HPLC with fluorescence detector. Berry samples from different locations in Chilean Patagonia, including different phenological stages, were systematically addressed. Results were compared with other organs of the plant and with other Berberis species. Total flavonol concentration in calafate (n = 65) was 1.33 ± 0.54 μmol/g. Glycosyl metabolites of quercetin and isorhamnetin were the most abundant. Similar profiles were observed in calafate from distinct locations, but important differences were observed for the other edible Berberis species. Calafate pulp and skin have higher flavonol concentrations than seeds, and the maturation process reduced its levels. TEACCUPRAC and TEACABTS of whole calafate extracts and fractions are also explored. Finally, only berberine was detected in the fruit (0.001%), mainly in seeds. Results contribute to the promotion of this berry as a superfruit from Patagonia.

    Edible plants with underground storage organs (USOs) are neglected resources. We studied the local ecological knowledge edible plants with (USOs) in rural populations of North-Patagonia in order to establish how people are utilizing these plants. Some aspect of corpus-praxis-cosmos complex associated to the local ecological knowledge was documented and discussed. In addition, variation in this ecological knowledge due to age, gender, family structure, ethnic self-determination was also evaluated. Semi-structured interviews were conducted with 51 inhabitants in order to study the relationship between the current use of plants with USOs and the age, sex, family group composition and ethnic self-identification of interviewees. In addition, the Cultural Importance Index for each species was calculated. The current richness of known species in these populations is a total of 9 plants. Plants with USOs tend to be used more frequently as the age of the interviewee increases. Women and men showed no differences in the average richness of species cited. The interviewees who share their homes with other generations use these plants more frequently than those who live alone. Our results indicate that the interviewees who identified themselves as belonging to the Mapuche people use these plants more frequently. For the Mapuche people, wild plants have constituted material and symbolic resources of great importance in their historical subsistence. In addition, they are currently being redefined as elements which present a connection with ancestral practices, produce a strong relationship with the 'land', and become markers which identify the 'natural' (historical) ways of their people; these are key elements in the current political processes of identity revaluation. This research is valuable to stimulate cultural revival and health promotion programs in the communities with their own local, cultural food.

    Mushrooms collected from a sub-alpine forest of Mt. Fuji and some other locations in Japan in 1996 were analyzed for radiocesium. The 137 Cs concentrations in 37 mushrooms varied widely from 1.6 to 783 Bqkg -1 fresh wt. The characteristics of Cs accumulation were analyzed by culturing fruiting bodies of the edible mushroom Pleurotus ostreatus (Fr.) Kummer Y-1 (P. ostreatus Y-1). The 137 Cs and stable Cs accumulation expressed as the concentration ratio (CR, 137 Cs or Cs concentration in the dried fruiting body/ 137 Cs or Cs concentration in the fresh medium) were in good agreement, indicating similar migration. The CR of Cs grown on medium containing both 0.1% Cs and 0.1% K, 10.2, showed a decrease of about 30 percent as compared with that containing 0.1% Cs only. These CR values suggested that Cs accumulation by the fruiting bodies of P. ostreatus Y-1 is affected by the presence of K similarly to previous observations in the mycelia. The 133 Cs-NMR spectra from the fruiting bodies of P. ostreatus Y-1 showed two resonance signals, whereas those from the media after harvesting of fruiting bodies showed only one signal. Just before growth of the fruiting bodies, bunches consisting of many mycelia were observed by scanning electron microscopy (SEM). No significant differences in the elemental distribution (Cs, K, P and C) were detected in the mycelium surface by SEM equipped with an energy dispersive X-ray microanalyzer. (author)

Methods: Fruits extracts were prepared with 80% aqueous acetone and evaluated for total phenolic contents (TPC and total flavonoid contents (TFC. Free radical scavenging activities [against 1,1-diphenyl-2-picryl-hydrazyl, 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid, linoleate hydroperoxyl and superoxide radicals], ferric reducing ability, ferrous metal chelating capacity, anti-elastase, anti-collagenase, anti-tyrosinase and anti-inflammatory activities were determined by using various in vitro assays. Results: TPC varied from 58.83 to 4 496.39 mg gallic acid equivalents/100 g fruit weight (FW, being highest in A. latifolia and lowest in F. subincisa. TFC ranged from 108.00 to 1 963.75 mg catechin equivalents/100 g FW, standing highest in L. asiatica and lowest in Prunus cerasoides. A. latifolia and L. asiatica possessed the highest antioxidant activities while B. asiatica and L. asiatica owned uppermost anti-elastase and anti-collagenase activities, respectively. B. asiatica revealed the highest anti-tyrosinase activity and F. subincisa demonstrated the highest antiinflammatory activity. The present study revealed differential contribution of TPC and TFC in various antioxidant activities. However, no obvious relationship was visible between antielastase/anti-collagenase/anti-tyrosinase/anti-inflammatory activities and TPC/TFC, suggesting the role of individual or combination of specific phenolics and flavonoids

    The total phenolic and flavonoid, antioxidant and antibacterial activities of six Sonchus wild vegetables (Sonchus oleraceus L., Sonchus arvensis L., Sonchus asper (L.) Hill., Sonchus uliginosus M.B., Sonchus brachyotus DC. and Sonchus lingianus Shih) in China were investigated. The results revealed that S. arvensis extract and S. oleraceus extract contained the highest amount of phenolic and flavonoid, respectively. Among the methanol extracts of six Sonchus species, S. arvensis extract exhibited the highest radical (DPPH and ABTS+ scavenging power and lipid peroxidation inhibitory power. It also exhibited the highest reducing power at 500 µg mL⁻¹ by A (700) = 0.80. The results of antibacterial test indicated that the S. oleraceus extract showed higher activity than the other five Sonchus wild vegetables extracts, both in Gram-negative bacteria (Escherichia coli, Salmonella enterica and Vibrio parahaemolyticus) and in a Gram-positive bacterium (Staphylococcus aureus). These results indicate that Sonchus wild food plants might be applicable in natural medicine and healthy food.

    The aim of this study was to quantify the content of polysaccharides of edible tender cladodes (nopalitos) of three species of Opuntia and to evaluate the rheological flow behavior of isolated polysaccharides. A completely randomized experimental design was used to characterize a wild (O. streptacantha), a semidomesticated (O. megacantha) and a domesticated (O. ficus-indica) species. Mucilage content was higher (4.93 to 12.43 g 100 g -1 dry matter), tightly bound hemicelluloses were lower (3.32 to 1.81 g 100 g -1 dry matter) and pectins and loosely bound hemicelluloses were not different in wild than in domesticated species. Aqueous solution/suspensions of mucilage, pectins, hemicellulose and cellulose of all species showed non-Newtonian behavior under simple shear flow. The flow behavior of the structural polysaccharides was well described by the Ostwald de-Waele model. Pectins and mucilages exhibited the highest consistency indexes (K values ranged from 0.075 to 0.177 Pas n ) with a moderated shear-thinning behavior (n values ranged from 0.53 to 0.67). Cellulose dispersions exhibited the most shear-thinning behavior (n values ranged from 0.17 to 0.41) and hemicelluloses showed a tendency to Newtonian flow (n values ranged from 0.82 to 0.97). The rheological flow properties of these polysaccharides may be useful to improve the textural and sensory qualities of some foods and pharmaceutical materials. Moreover, they can emerge as functional ingredients mainly due to the nutraceutical properties that have been attributed to nopalitos.

    Edible wild mushroom picking is becoming an important source of income in rural areas. The wide range of activities which add value to mycological production (initial sale, transformation, marketing, etc.) include those related to tourism which can attract visitors to mushroom producing areas, leading to so-called mycological tourism. To date, no research exists quantifying the importance thereof in rural areas endowed with such resources. The present research provides the first model to estimate this activity contribution to the economy of rural areas in the region of Castilla y Leon. The main finding to emerge evidences a close link between influx of visitors, who come principally to pick, and mycological productivity in the region. Based on this relation, we estimate four key variables to determine the impact which said activity has on the regional economy as a whole: the number of overnight stays and trips made by mycological tourists, as well as associated expenditure and employment created. Findings underscore the importance of this activity in the regional tourism industry and point to its significance as a major market niche, particularly during the hotel low season. The need for public administrators to implement a related management policy is also inferred. (Author) 35 refs.

    This study is a systematic overview of data on use of wild and semi-wild edible plants in nutrition of people in 1430 days of the siege of Sarajevo during aggression on Bosnia and Herzegovina (1992-1995). The author of this study spent all that time in Sarajevo. In 1993, the author prepared a survival program for people that included usage of edible wild plants. In addition, he conducted a detailed survey, including special interviews, on 630 people of average age 37.4 years (55% residential inhabitants, the rest were refuges), 310 males and the rest were females. According to survey, 91 species of mostly wild plants and three species of fungus were used: Küchneromyces mutabilis, Armillariella mellea and Coprinus comatus. Wild vegetables included 49 species, spices 24, wild fruits 16, and 2 species of bread-plants. They belong to 26 plants communities, and grew on 24 different habitats (urban surfaces, river coasts, low forest and scrubs, meadows and rocky grasslands). The 156 plant parts (leaves, young branches, fruit, flower, seed, root and rhizome) from 91 plant species were used. Vegetables were dominant category of use (soups, pottages, sauces) with 80 ways of preparation (30.53%), then salads 41 (15.65%), spices 39 (14.89%), different beverages 38 (14.50%), sweets 21 (8.02%), nutritive teas 15 (5.73%), and other preparations. In order to improve conventional food (war pasta, rice, lentils, old beans) people used spices made from different wild plants.

    The harvesting, utilization and marketing of indigenous fruits and nuts have been central to the livelihoods of the majority of rural communities in African countries. In this study we report on the content of dietary fiber, minerals and selected organic acids in the pulps and kernels of the wild fruits most commonly consumed in southern Mozambique. The content of soluble fiber in the pulps ranged from 4.3 to 65.6 g/100 g and insoluble fiber from 2.6 to 45.8 g/100 g. In the kernels the content of soluble fiber ranged from 8.4 to 42.6 g/100 g and insoluble fiber from 14.7 to 20.9 g/100 g. Citric acid was found in all fruits up to 25.7 g/kg. The kernels of Adansonia digitata and Sclerocarya birrea were shown to be rich in calcium, iron, magnesium and zinc. The data may be useful in selecting wild fruit species appropriate for incorporation into diets.

    Full Text Available The kinetics solid-liquid extraction of phenolics from wild olive leaves was elaborated using different mathematical models (Peleg, second order, Elovich, and power law model. As solvents, methanol, ethanol, ethanol:water 1:1, n-propanol, isopropanol and ethyl acetate were used. The second order model best described the solvent extraction process, followed by the Elovich model. The most effective solvent was ethanol with optimum phenol extraction conditions 180 min, solvent to sample ratio 5:1 v/w and pH 2. Ethanol extract exhibited the highest antiradical activity among solvent and supercritical fluid extraction (SFE extracts, which in addition showed the highest antioxidant capacity compared to synthetic and natural food antioxidants such as BHT, ascorbyl palmitate and vitamin E. Antioxidant potential of SFE extract was quite high, although its phenolic potential was not. Leaf extracts were proven to be good protectors for olive and sunflower oils at levels of 150 ppm.

    Full Text Available Many mushrooms species are known to accumulate metals to a higher level than the plants and are considered as a source of proteins, vitamins – riboflavin, biotin and thiamine, fats, carbohydrates, amino acids and minerals. The trace metals concentrations were established by Inductively Coupled Plasma - Atomic Emission Spectrometry method. The aim of this paper is to determinate the minerals content of some wild growing mushrooms, which may be useful in the phytopharmaceutical biotechnologies in order to obtain important quantities of biominerals accessible for the human body. The results are varying with the analyzed species of mushrooms between 11869.85 and 32088.68 mg/kg for potassium, 240.81 to 716.98 mg/kg for calcium and between 0 to 5350 mg/kg for phosphorus. The highest concentration if potassium was founded in B. griseus species, 32088.68 mg/kg. Only two species, Hygrophorus virgineus and Marasmius oreades show a phosphorus concentration in the fruiting body higher than in soil, indicating the accumulation capacity.

    Full Text Available The aim of this review is to present an overview of changes in the contemporary use of wild food plants in Europe, mainly using the examples of our home countries: Poland, Italy, Spain, Estonia and Sweden. We set the scene referring to the nutrition of 19th century peasants, involving many famine and emergency foods. Later we discuss such issues as children's wild snacks, the association between the decline of plant knowledge and the disappearance of plant use, the effects of over-exploitation, the decrease of the availability of plants due to ecosystem changes, land access rights for foragers and intoxication dangers. We also describe the 20th and 21st century vogues in wild plant use, particularly their shift into the domain of haute-cuisine.

    The lipid content and fatty acid composition in the edible meat of twenty-nine species of wild and cultured freshwater and marine fish and shrimps were investigated. Both the lipid content and fatty acid composition of the species were specified due to their unique food habits and trophic levels. Most of the marine fish demonstrated higher lipid content than the freshwater fish, whereas shrimps had the lowest lipid content. All the marine fish and shrimps had much higher total n-3 PUFA than n-6 PUFA, while most of the freshwater fish and shrimps demonstrated much lower total n-3 PUFA than n-6 PUFA. This may be the biggest difference in fatty acid composition between marine and freshwater species. The cultured freshwater fish demonstrated higher percentages of total PUFA, total n-3 PUFA, and EPA + DHA than the wild freshwater fish. Two freshwater fish, including bighead carp and silver carp, are comparable to the marine fish as sources of n-3 PUFA.

    The present study deals with the valorization of an edible spontaneous plant of the Tunisian arid areas: Allium roseum. This plant is traditionally used for therapeutic and culinary uses. Thin-layer drying behavior of Allium roseum leaves was investigated at 40, 50 and 60 °C drying air temperatures and 1 and l.5 m/s air velocity, in a convective dryer. The increase in air temperature significantly affected the moisture loss and reduced the drying time while air velocity was an insignificant factor during drying of Allium roseum leaves. Five models selected from the literature were found to satisfactorily describe drying kinetics of Allium roseum leaves for all tested drying conditions. Drying data were analyzed to obtain moisture diffusivity values. During the falling rate-drying period, moisture transfer from Allium roseum leaves was described by applying the Fick's diffusion model. Moisture diffusivity varied from 2.55 × 10(-12) to 8.83 × 10(-12) m(2)/s and increased with air temperature. Activation energy during convective drying was calculated using an exponential expression based on Arrhenius equation and ranged between 46.80 and 52.68 kJ/mol. All sulfur compounds detected in the fresh leaves were detected in the dried leaves. Convective air drying preserved the sulfur compounds potential formation.

    In the present study, the composition of bio-elements (K, Na, Mg, Ca, Fe, Cu, Zn) and toxic elements (Ag, Cd) in seven edible mushrooms from the rural and woodland region of Morąg (north-eastern Poland) and the rural and industrial region of the Tarnobrzeska Upland (south-eastern Poland) were investigated using a validated method. The species examined were Boletus edulis, Cantharellus cibarius, Leccinum aurantiacum, Leccinum versipelle, Lycoperdon perlatum, Suillus luteus, and Xerocomus subtomentosus. Final determination was carried out by flame atomic absorption spectroscopy (FAAS) after microwave-assisted decomposition of sample matrices with solutions of concentrated nitric acid in the pressurized polytetrafluoroethylene vessels. The contents of the alkali elements and alkali earth elements were determined in the species surveyed. The alkali elements, earth alkali elements, and transition metals (Ag, Cu, Zn, Fe, and Mn) were at typical concentrations as was determined for the same or similar species elsewhere in Poland and Europe. The results may suggest a lack of local and regional emissions of those metallic elements from industrialization of some sites in the Tarnobrzeska Plain. Cadmium was at elevated concentrations in L. versipelle from the Tarnobrzeska Plain but the reason-pollution or geogenic source-was unknown, while it was at typical concentrations in other species.

    2016-08-01

    Full Text Available In Sub-Saharan Africa, especially, in Côte d’Ivoire, the wild edible mushroom Termitomyces heimii Natarajan is the most prized and widely consumed for different reasons such as taste, flavour, attractiveness, uses as substitutes for meat or fish and medicinal values. The present study was aimed at evaluating the proximate composition and functional properties of T. heimii flour for further food products formulation. Fresh mushroom T. heimii were obtained from the market of Aboisso (5° 28′ 06″ N and3° 12′ 25″ W in Côte d’Ivoire. The fresh mushrooms were dried and ground to obtain the crude flour. Chemical composition and functional properties were investigated using standard methods. The chemical composition revealed that it contains crude protein about 23.75%, crude fat 3.58%, moisture 11.59 %, ash 7.40%, total carbohydrate 54.70% and energy value of 345.90 kcal/ 100 g. These results suggest that T. heimii can be used in human diet to prevent undernourishment due to protein. Furthermore, the low fat content suggest that it would be an ideal food for obese persons and useful in preventing hypertension and hypercholesterolemia. The functional properties showed that it has high bulk density and water absorption capacity with values of 0.737 g/mL and 315.15 ± 45.74% respectively. This flour exhibited also good foaming properties. All these characteristics make it suitable as good thickeners in food products, useful in foods such as bakery products which require hydration and attractive for products like cakes or whipping topping where foaming is important. The mushroom T. heimii could be utilized for making some low-fat foodstuffs and snacks with considerable protein content. The mushroom flour shows good functional characteristics for use in many food industries.

    Objective: To determine the activity concentration of radionuclides for "1"3"7Cs and "4"0K in edible wild mushrooms, and to evaluate the extent of radioactive contamination and ingestion doses to adults from consumption of these wild mushrooms. Methods: A total of 33 samples for 18 edible wild mushroom species were collected from natural forest Mangshi, Yunnan province. The activity concentrations of "1"3"7Cs and "4"0K were analyzed by using high-purity germanium (HPGe) gamma spectrometry. Results: Except for one sample that was below the MDA, "1"3"7Cs artificial radionuclides were detected in other 32 samples, with activity concentration of "1"3"7Cs in the range of 0.45-339.58 Bq/kg (dry weight) and an average of 25.47 Bq/kg (dry weight). In regards to "4"0K in edible mushrooms, all species presented the activity concentrations for this radionuclide and the levels varied from 453.4 to 1882.6 Bq/kg (dry weight), with an average of 815.1 Bq/kg (dry weight). After species of mushroom with only one sample were eliminated, there was significant difference for "1"3"7Cs(F = 21.13, P < 0.05) among 6 species of mushroom named Gomphus floccosus (Schw.) Sing., Boletus edulis bull, Boletus edulis bull, Tylopllus bolloul (Peck) Sing., Lentinus edodes (Berk.) Sing. and Boletus brunneissimus W.F.Chin, but without significant difference for "4"0K. Conclusions: These 6 different mushroom species have different capacity to retain radionuclides of "1"3"7Cs in soil. These wild mushrooms, such as Gomphus floccosus (Schw.) Sing. and Lentinus edodes (Berk.) Sing. have large affinity ability for radionuclides"1"3"7Cs. The effective dose to adults attributable to consuming these kinds of mushrooms is small and below the level that could cause harm. (authors)

  2. Antioxidants of Edible Mushrooms

    2015-10-01

    Full Text Available Oxidative stress caused by an imbalanced metabolism and an excess of reactive oxygen species (ROS lead to a range of health disorders in humans. Our endogenous antioxidant defense mechanisms and our dietary intake of antioxidants potentially regulate our oxidative homeostasis. Numerous synthetic antioxidants can effectively improve defense mechanisms, but because of their adverse toxic effects under certain conditions, preference is given to natural compounds. Consequently, the requirements for natural, alternative sources of antioxidant foods identified in edible mushrooms, as well as the mechanistic action involved in their antioxidant properties, have increased rapidly. Chemical composition and antioxidant potential of mushrooms have been intensively studied. Edible mushrooms might be used directly in enhancement of antioxidant defenses through dietary supplementation to reduce the level of oxidative stress. Wild or cultivated, they have been related to significant antioxidant properties due to their bioactive compounds, such as polyphenols, polysaccharides, vitamins, carotenoids and minerals. Antioxidant and health benefits, observed in edible mushrooms, seem an additional reason for their traditional use as a popular delicacy food. This review discusses the consumption of edible mushrooms as a powerful instrument in maintaining health, longevity and life quality.

    True or false? In selling high-value products or services: "closing" increases your chance of success; it is essential to describe the benefits of your product or service to the customer; objection handling is an important skill; and open questions are more effective than closed questions. All false, says Neil Rackham. He and his team studied more than 35,000 sales calls made by 10,000 sales people in 23 countries over 12 years. Their findings revealed that many of the methods developed for selling low-value goods just don't work for major sales. Rackham went on to introduce his SPIN-selling method, where SPIN describes the whole selling process - Situation questions, Problem questions, Implication questions, Need-payoff questions. SPIN-selling provides you with a set of simple and practical techniques which have been tried in many of today's leading companies with dramatic improvements to their sales performance.

    Selenium is vital to human health. This article is a compendium of virtually all the published data on total selenium concentrations, its distribution in fruitbody, bioconcentration factors, and chemical forms in wild-grown, cultivated, and selenium-enriched mushrooms worldwide. Of the 190 species reviewed (belonging to 21 families and 56 genera), most are considered edible, and a few selected data relate to inedible mushrooms. Most of edible mushroom species examined until now are selenium-poor (cesarea, A. campestris, A. edulis, A. macrosporus, and A. silvaticus. A particularly rich source of selenium could be obtained from selenium-enriched mushrooms that are cultivated on a substrate fortified with selenium (as inorganic salt or selenized-yeast). The Se-enriched Champignon Mushroom could contain up to 30 or 110 microg Se/g dw, while the Varnished Polypore (Ganoderma lucidum) could contain up to 72 microg Se/g dw. An increasingly growing database on chemical forms of selenium of mushrooms indicates that the seleno-compounds identified in carpophore include selenocysteine, selenomethionine, Se-methylselenocysteine, selenite, and several unidentified seleno-compounds; their proportions vary widely. Some aspects of environmental selenium occurrence and human body pharmacokinetics and nutritional needs will also be briefly discussed in this review.

    A number of wild crops remain unexplored in this world and among them some have excellent medicinal and nutritional properties. India is a harbor of biodiversity in general and phytodiversity in particular. The plant diversity is distributed from the Western Ghats to Eastern Ghats, along with the North-Eastern region and from the Greater Himalayas to the plain of Ganga. Among these distributed floral regions of the country, the Eastern Ghats are important due to their rich floral diversity. The forests of Odisha form a major part of Eastern Ghats in general and the Similipal Biosphere Reserve (SBR) in particular. The SBR is inhabited by many local communities. The food and medicinal habits of these communities are not fully explored even today. They are dependent on the forests of SBR for their food and medicine. Among their collections from forests, root and tuberous plants play a significant role. The local communities of SBR use about 89 types of tuberous plants for various purposes. Dioscorea is one such tuber, having maximum use among the local of SBR. However, less documentation and no specific reports are available on the food and medicinal values of the species available in this part of the World. Dioscorea species, popularly known as Yam worldwide and as Ban Aalu in Odisha, India, is a prime staple medicinal-food substitute for the majority of rural and local people of the state of India. Of the 13 Dioscorea species available in SBR, 10 species are known to be bitter in taste and unpalatable when taken raw. Since less documentation is available on the Dioscorea species of SBR and their traditional uses, the present study was focused on the ethnobotany, nutritional and pharmacological values of these species along its nutraceutical importance.

    2010-01-01

    Research groups and the food and pharmaceutical industries recognize edible packaging as a useful alternative or addition to conventional packaging to reduce waste and to create novel applications for improving product stability, quality, safety, variety, and convenience for consumers. Recent studies have explored the ability of biopolymer-based food packaging materials to carry and control-release active compounds. As diverse edible packaging materials derived from various by-products or waste from food industry are being developed, the dry thermoplastic process is advancing rapidly as a feasible commercial edible packaging manufacturing process. The employment of nanocomposite concepts to edible packaging materials promises to improve barrier and mechanical properties and facilitate effective incorporation of bioactive ingredients and other designed functions. In addition to the need for a more fundamental understanding to enable design to desired specifications, edible packaging has to overcome challenges such as regulatory requirements, consumer acceptance, and scaling-up research concepts to commercial applications.

  18. Selling the brand inside.

    Science.gov (United States)

    Mitchell, Colin

    2002-01-01

    When you think of marketing, chances are your mind goes right to your customers--how can you persuade more people to buy whatever it is you sell? But there's another "market" that's equally important: your employees. Author Colin Mitchell argues that executives by and large ignore this critical internal audience when developing and executing branding campaigns. As a result, employees end up undermining the expectations set by the company's advertising--either because they don't understand what the ads have promised or because they don't believe in the brand and feel disengaged or, worse, hostile toward the company. Mitchell offers three principles for executing internal branding campaigns--techniques executives can use to make sure employees understand, embrace, and "live" the brand vision companies are selling to the public. First, he says, companies need to market to employees at times when the company is experiencing a fundamental challenge or change, times when employees are seeking direction and are relatively receptive to new initiatives. Second, companies must link their internal and external marketing campaigns; employees should hear the same messages that are being sent to the market-place. And third, internal branding campaigns should bring the brand alive for employees, creating an emotional connection to the company that transcends any one experience. Internal campaigns should introduce and explain the brand messages in new and attention-grabbing ways and then reinforce those messages by weaving them into the fabric of the company. It is a fact of business, writes Mitchell, that if employees do not care about or understand their company's brands, they will ultimately weaken their organizations. It's up to top executives, he says, to give them a reason to care.

    Since 2009, millions of people have been forced to live under food shortage by the continuous drought in Southwestern China. The market was the primary source of aid grains, and fears that the market will be unable to provide sufficient food make safeguarding food security in the face of climate change crucial. Traditional adaptive strategies of pre-market indigenous people are a potential source of innovation. We studied three questions among the Naxi people: 1) What edible plants did they consume during droughts? 2) How did they produce enough food? 3) How did they consume these plants? This study investigates and documents traditional Naxi food knowledge to safeguard food security during drought and facilitate Chinese policy decisions. Ethnobotanical investigation was conducted through literature review, semi-structured interviews, collaborative fieldwork and group discussions in three Naxi villages. 89 informants (including 35 key informants) were surveyed from 2012 to 2013. Significant Index (SI) was adopted to evaluate each edible plant's food supply significance. Voucher specimens were collected for taxonomic identification. 1) In total, 141 edible plants (38 cultivated and 103 wild) were consumed-primarily landrace crops, supplementary edible plants and famine plants. 2) Naxi people produced sufficient food through widespread food production systems, strong landrace crop resilience, and diversity in wild edible plants. 3) Through a diverse diet and consuming almost all edible parts of the plant, the Naxi used edible plants fully to meet food and nutrition needs during drought. Edible plant diversity is a cornerstone of drought food security. Cultivated crops (especially landrace plants) and wild edible plants were both important. Naxi people protect edible plant diversity through ecological morality and traditional ecological knowledge (TEK). National inventories of edible plant diversity and studies of the TEK of other Chinese indigenous peoples should be

    Full Text Available Between 1962-1986 the Yugoslav Army carried out a project in which Josip Bakić from the Institute for Naval Medicine of the Yugoslav Navy in Split took the main professional role. In the project, amongst other activities, Bakić and his team explored the possibility of soldiers’ survival on the Adriatic islands based on wild plants and marine animals. As a part of this project, wild food plants and animals from the coast that had been used by the population during World War I and II were surveyed. Some phytochemical properties of the plants were also studied. Educa- tion of soldiers and the wider public was provided based on the results of the research and experiments. The project is a unique example of combining a scientific study with a practical military experiment. Apart from scientific papers the results were also popularized as a survival handbook, a book about nutrition from nature, film documentaries, and workshops. In this paper we summarize the achievements of this project based on the review of published data and interviews with Josip Bakić.

    The concentration levels of 20 metals were analyzed by ICP-OES in edible seaweed (Chondrus, Eisenia, Gelidium, Himanthalia, Laminaria, Palmaria, Porphyra, Undaria), from two origins (Asia vs EU) according to their cultivation practices (conventional vs organic). Red seaweed showed higher concentrations of trace and toxic elements. Porphyra may be used as a potential bioindicator for metals. Significant differences were found between the Asian vs European mean contents. The mean Cd level from the conventional cultivation (0.28 mg/kg) was two points higher than the organic cultivation (0.13 mg/kg). A daily consumption of seaweed (4 g/day) contributes to the dietary intake of metals, mainly Mg and Cr. The average intakes of Al, Cd and Pb were 0.064, 0.001 and 0.0003 mg/day, respectively. Based on obtained results, this study suggests that exposure to the toxic metals analyzed (Al, Cd and Pb) through seaweed consumption does not raise serious health concerns, but other toxic metals should be monitored.

  10. Selling science to the public

    CERN Document Server

    Catapano, Paola

    1997-01-01

    Science popularization is ÒtheÓ tool to bridge the gap between society at large and the world of science. Compared to formal science communication Ð science taught in schools Ð informal science communication, made by the TV, the press, Òscience centresÓ and visits to scientific laboratories, has an important advantage: it makes the public meet science in a direct, informal way and on its own terms. The public is given an opportunity to develop a personal relationship with science, according to the needs, interests and abilities of the individual. But selling science is a tough job. The object of the sale is not a consumer good, but rather ideas and concepts that are sometimes so complex and distant from common sense that translating them into a comprehensible language and creating interest in the public without betraying the scientific truth is almost impossible. In the research work conducted for the thesis the importance of adopting a marketing approach in science communication is presented. Any scien...

  11. Edible insects are the future?

    Science.gov (United States)

    van Huis, Arnold

    2016-08-01

    The global increase in demand for meat and the limited land area available prompt the search for alternative protein sources. Also the sustainability of meat production has been questioned. Edible insects as an alternative protein source for human food and animal feed are interesting in terms of low greenhouse gas emissions, high feed conversion efficiency, low land use, and their ability to transform low value organic side streams into high value protein products. More than 2000 insect species are eaten mainly in tropical regions. The role of edible insects in the livelihoods and nutrition of people in tropical countries is discussed, but this food source is threatened. In the Western world, there is an increasing interest in edible insects, and examples are given. Insects as feed, in particular as aquafeed, have a large potential. Edible insects have about the same protein content as conventional meat and more PUFA. They may also have some beneficial health effects. Edible insects need to be processed and turned into palatable dishes. Food safety may be affected by toxicity of insects, contamination with pathogens, spoilage during conservation and allergies. Consumer attitude is a major issue in the Western world and a number of strategies are proposed to encourage insect consumption. We discuss research pathways to make insects a viable sector in food and agriculture: an appropriate disciplinary focus, quantifying its importance, comparing its nutritional value to conventional protein sources, environmental benefits, safeguarding food safety, optimising farming, consumer acceptance and gastronomy.

    Full Text Available This paper aims at providing insight into some of the implication of short selling for markets, investors as well as regulators. Findings show that capital flows are adversely affected by strict regulation and bans of short sales, while market liquidity, and bid-ask spread can be improved by allowing short selling. Additionally portfolios that incorporate short selling strategies can have lower volatility in returns. The informational content of short sales can provide important feedback for informed investors and lead to better price discovery.

  13. Selling to the moneyed masses.

    Over the past decade, the distribution of household incomes has shifted so much that a much larger proportion of consumers now earn significantly higher-than-average incomes--while still falling short of being truly rich. As a result, what used to be a no-man's-land for new product introductions has in many categories become an extremely profitable "new middle ground." How can marketers capitalize on this new territory? The key, say the authors, is to rethink the positioning and design of offerings and the ways they can be brought to market. Take, for instance, how Procter & Gamble redefined the positioning map for tooth-whitening solutions. A decade ago, dental centers were popularizing expensive bleaching techniques that put the price of a professionally brightened smile in the 400 dollars range. At the low end, consumers also had the choice of whitening toothpastes that cost anywhere from 2 dollars to 8 dollars. P&G wisely positioned itself between the two ends, successfully targeting the new mass market with its 35 dollars Whitestrips. In product categories where it's clear the middle ground has already been populated, it's important for companies to design or redesign offerings to compete. An example is the Polo shirt. How do you sell a man yet another one after he's bought every color he wants? Add some features, and call it a golf shirt. Here, marketers have introduced designs based on the concept of "occasional use" in order to stand out. Finally, companies wishing to reach the "almost rich" can change how they go to market. Perhaps no mass retailer has made a stronger bid for the mass affluent than Target Stores, which has pioneered a focus the company itself characterizes as upscale discount. The strategy has made Target an everyday shopping phenomenon among well-heeled urbanites and prosperous professionals.

  14. Censoring and Selling Film Noir

    Directory of Open Access Journals (Sweden)

    Sheri Chinen Biesen

    2015-05-01

    Full Text Available Film noir is known for its duplicity. Industry censors considered 1940s noir cinema provocative, salacious and ‘sordid.’ Hollywood studios walked a fine line between appearing to comply with Hays office Production Code censorship while simultaneously pushing the envelope of its moral constraints, then hyping and sensationalizing censorable sex, violence and hard-hitting themes to sell noir films to the public. In fact, studios capitalized on the racy explicit nature of noir pictures in publicity contradicting assurances of censorial compliance. For instance, censor Joseph Breen was “shocked” when MGM purchased James Cain’s The Postman Always Rings Twice. It was banned for a decade. Yet, ten years later as filmmakers adapted hardboiled fiction, Breen assured religious groups it would “not be offensive.” Yet, it was promoted as “torrid,” “too hot to handle” with Lana Turner in a bathing suit finding “Love at Laguna Beach” with hunky John Garfield who clamored, “You must be a she-devil,” suggesting far more sex, skin and “savage boldness” than is shown in the film. Film noir responded to Production Code censorship and other regulatory factors, including Office of War Information Bureau of Motion Pictures restrictions on Hollywood screen depictions of the domestic American home front (or overseas combat front, and Office of Censorship strictures such as a wartime ban on screen gangsters as ‘un-American’ for propaganda purposes in World War II-era noir films centering on criminals. These multiple censorship entities often collided. This regulatory climate catalyzed the development of film noir, a dark cycle of shadowy 1940s-50s crime films that boomed by World War II and evolved over the postwar era. I will investigate extensive primary archival research—including scripts, memos from industry censors, writers, directors, producers, and publicity records—to compare how film noir was censored and sold.

  6. Reconsidering Kantian arguments against organ selling.

    Science.gov (United States)

    Alpinar-Şencan, Zümrüt

    2016-03-01

    Referring to Kant's arguments addressing the moral relationship between our bodies and ourselves is quite common in contemporary debate about organ selling, although he does not provide us with any specific arguments related to this debate. It is widely argued that the most promising way to show the moral impermissibility of organ selling is to mount an argument on Kantian grounds. This paper asks whether it is possible to argue coherently against organ selling in a Kantian framework. It will be shown that by mounting the argument on Kantian grounds no compelling argument can be given against sale of organs, either because the arguments apply to donation of organs, too, or the arguments are not convincing for other independent reasons. In the first section, it will be argued that donation and selling are not distinguishable in a Kantian framework, since the concern about commodification of the body and its parts shall be raised by both actions. In the second section, some contemporary accounts inspired by Kant will be presented and discussed separately. It will be argued that the reasons for promoting organ donation while arguing against selling clash with each other in an unconvincing way.

    Several states in the U.S. have legalized cannabis for recreational or medical uses. In this context, cannabis edibles have drawn considerable attention after adverse effects were reported. This paper investigates Twitter users' perceptions concerning edibles and evaluates the association edibles-related tweeting activity and local cannabis legislation. Tweets were collected between May 1 and July 31, 2015, using Twitter API and filtered through the eDrugTrends/Twitris platform. A random sample of geolocated tweets was manually coded to evaluate Twitter users' perceptions regarding edibles. Raw state proportions of Twitter users mentioning edibles were ajusted relative to the total number of Twitter users per state. Differences in adjusted proportions of Twitter users mentioning edibles between states with different cannabis legislation status were assesed via a permutation test. We collected 100,182 tweets mentioning cannabis edibles with 26.9% (n=26,975) containing state-level geolocation. Adjusted percentages of geolocated Twitter users posting about edibles were significantly greater in states that allow recreational and/or medical use of cannabis. The differences were statistically significant. Overall, cannabis edibles were generally positively perceived among Twitter users despite some negative tweets expressing the unreliability of edible consumption linked to variability in effect intensity and duration. Our findings suggest that Twitter data analysis is an important tool for epidemiological monitoring of emerging drug use practices and trends. Results tend to indicate greater tweeting activity about cannabis edibles in states where medical THC and/or recreational use are legal. Although the majority of tweets conveyed positive attitudes about cannabis edibles, analysis of experiences expressed in negative tweets confirms the potential adverse effects of edibles and calls for educating edibles-naïve users, improving edibles labeling, and testing their THC

    To obtain insight into tobacco retailing by alcohol-licenced premises, in order to understand the financial importance of tobacco sales for such retailers. Data were collected by a telephone survey of 1042 clubs, hotels and packaged liquor outlets in New South Wales, Australia. The response rate was 86.1%. Qualitative and quantitative data were obtained. Logistic and linear regression were used to determine factors associated with the probability of selling and stopping selling and the importance of cigarette sales. More than a third (36.4%) of premises contacted did not sell cigarettes. 147 (an estimated 18.1% of those who had ever sold) had stopped selling. There were significant differences in the probability of selling, in the reported importance of cigarette sales and in the probability of stopping selling, between different outlet types and other outlet characteristics (number of gaming machines, proximity of nearest alternative tobacco retailer and remoteness). Outlets where alcohol can be consumed were more likely to rate cigarette sales as 'not important' than 'important'. Despite claims by tobacco companies that tobacco sales are important for many Australian retailers, tobacco sales appear to be of limited importance for alcohol-licenced premises. This means that opposition to stopping tobacco sales where alcohol is consumed and/or sold may be less than expected. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  1. Sewage sludge and how to sell it

    Energy Technology Data Exchange (ETDEWEB)

    Knapp, I M

    1977-10-01

    Largo, Florida dries its sludge and sells it as fertilizer for $80 to $169/T. The sludge processing plant capable of turning common sludge into a dry, pelletized soil conditioner was only slightly more expensive than the previously proposed concrete drying beds which would have required disposal of the dried residue. The city's experience in setting up the plant and marketing the finished product is discussed. The true advantage of selling heat-dried sludge is that residents of the surrounding area, knowing the value of the product to their lawns and shrubs, will provide the transportation for the product and the physical labor to spread it over an area wider than most municipalities could afford to own or operate. The current production cost of $140/T is high, but the addition of a sludge prethickener-conditioner process and expected future economies of scale as the volume of sludge treated increases should lower per ton costs.

    2017-11-01

    Shortages in the number of donated organs after death and the growing number of end-stage organ failure patients on waiting lists call for looking at alternatives to increase the number of organs that could be used for transplantation purposes. One option that has led to a legal and ethical debate is to have regulated markets in human organs. Opponents of a market in human organs offer different arguments that are mostly founded on contingent factors that can be adjusted. However, some authors have asked the question whether we still have a reason to believe that there is something wrong with offering human organs for sale for transplantation purposes, even if the circumstances under which the practice takes place are improved. One prominent argument regarding this appeals to the notion of human dignity. It is argued that organ selling violates human dignity. This paper presents a systematic discussion of dignity-based arguments in the organ selling debate, and then develops a social account of dignity. It is argued that allowing the practice of organ selling inherently runs the risk of promoting the notion that some persons have less worth than others and that persons have a price, which is incompatible with dignity. The approach is defended against possible objections and it is shown that it can capture the notion that autonomy is linked to human dignity in important ways, while dignity at the same time can constrain the autonomous choices of persons with regards to certain practices.

    Full Text Available Coffee (Coffea arabica L. is one of the most economically, socioculturally and environmentally important crops in Veracruz. Shade-grown coffee plantations provide environmental services and play a key role in biodiversity conservation. In coffee farms in Veracruz insects are an abundant natural resource, and part of the use of this resource is the consumption of some edible insects in certain coffee regions. The objective of this study was to know the traditional use of three species of edible insects in the coffee agroecosystem of Veracruz. During the period 2007-2012, an ethnoentomological study was conducted in coffee regions from central Veracruz. The insect species identified were the ants chicatanas (Atta mexicana Smith and Atta cephalotes Latreille in the municipality of Huatusco, the larva gusano del jonote (Arsenura armida armida Cramer in the municipalities of Zongolica, Tequila and Tezonapa, and the larva gusanillo (Phassus triangularis H.E. in the municipalities of Córdoba, Ixhuatlán del Café, Tepatlaxco, Chocamán and Zongolica. The results showed the traditional knowledge held by coffee growers related to these edible species which are a valuable natural resource in their coffee plantations. Knowledge on agroecological relationships, collection, consumption and marketing was rescued. In conclusion, the insect species studied are used for local consumption and have great economic potential due to their high sell price during the harvest season.

    2017-11-01

    Edible films containing essential oils (EO) as natural antibacterial agents are promising systems for food preservation. In this work, nanoemulsions of Thymus daenensis EO (wild; F1 and cultivated; F2) were loaded in hydroxyl propyl methyl cellulose (HPMC) films and the effect of different parameters (polymer, plasticizer, and EO concentration) on the film properties were analyzed and optimized. Prepared HPMC films were characterized in terms of EO loading, morphology, mechanical properties, and the antibacterial activity. The results of SEM showed uniform incorporation of nanoemulsions into the edible film. Investigation of the mechanical properties of two edible films revealed a plasticizing effect of T. daenensis EO on the films. Also, edible films had noticeable antimicrobial activity against selected microorganisms, i.e. 47.0±2.5mm and 22.6±0.5mm zone of inhibition against S. aureus for films containing F1 and F2, respectively. Incorporation of nanoemulsions into the HPMC films can be used for active food preservation. Copyright © 2017 Elsevier Ltd. All rights reserved.

  18. Selling eugenics: the case of Sweden.

    Science.gov (United States)

    Bjorkman, Maria; Widmalm, Sven

    2010-12-20

    This paper traces the early (1910s to 1920s) development of Swedish eugenics through a study of the social network that promoted it. The eugenics network consisted mainly of academics from a variety of disciplines, but with medicine and biology dominating; connections with German scientists who would later shape Nazi biopolitics were strong. The paper shows how the network used political lobbying (for example, using contacts with academically accomplished MPs) and various media strategies to gain scientific and political support for their cause, where a major goal was the creation of a eugenics institute (which opened in 1922). It also outlines the eugenic vision of the institute's first director, Herman Lundborg. In effect the network, and in particular Lundborg, promoted the view that politics should be guided by eugenics and by a genetically superior elite. The selling of eugenics in Sweden is an example of the co-production of science and social order.

    Full Text Available The determination of the price should meet certain criteria, both from the society and the company itself. The combination of various criteria will result in another problem. Fuzzy Logic covers all influencing factors and displays the membership function graphic. Furthermore, by implementing fuzzy rules and fuzzy operator, the right price can be determined which covers all the factors above. The determination of the rules is based on the raw material cost, direct labor cost, distribution cost and the customers' opinion regarding the appropriate price. Then, the model is designed with the help of Matlab software. The result is finally obtained in the form of a model performed by Matlab software. The model displays the output concerning the selling price of the product for each change in the dominant factors.

  20. Modeling switching behaviour of direct selling customers

    Directory of Open Access Journals (Sweden)

    P Msweli-Mbanga

    2004-04-01

    Full Text Available The direct selling industry suffers a high turnover rate of salespeople, resulting in high costs of training new salespeople. Further costs are incurred when broken relationships with customers cause them to switch from one product supplier to another. This study identifies twelve factors that drive the switching behaviour of direct sales customers and examines the extent to which these factors influence switching. Exploratory factor analysis was used to assess the validity of these factors. The factors were represented in a model that posits that an interpersonal relationship between a direct sales person and a customer moderates the relationship between switching behaviour and loyalty. Structural equation modeling was used to test the proposed model. The author then discusses the empirical findings and their managerial implications, providing further avenues for research.

    2009-01-01

    Full Text Available Media globalization is facilitated by the development of new technologies within a framework of digitization and convergence. Contemporary new media provide networks through which the mingling of media occurs, shaping a “multi-mediacy” age, and a connecting of mediated/mediating venues in a condition of “immediacy”. Additionally, the business of communication has evolved from being the “communication of business” to the “business of business”. Multi-mediacy and immediacy have generated new avenues of profit from media. The paper will draw on Chitty’s theorization on web transactional venues to discuss new ways of farming of revenue from media. Media revenues have in the past and today been drawn from licence fees, media subscriptions and advertising. Today, media networks also sell “participation” to audiences directly by charging for text message voting/gaming, or sell a range of products and services through web-venue based commerce. This paper will undertake case studies to examine the increasing trend of “direct audience payment for participation”. The case studies that will be used are (A the intervention of Chinese Service Providers in reality TV shows and (B E-commerce on the Internet. Monternet (mo[bile I]nternet and Linktone are investigated as Service Providers (SPs and the consumer-to-consumer (C2C website www.taobao.com is studied compared with Eachnet (eBay in China. The paper will also investigate the influences of “direct audience payment for participation” on the quality of media products and communication flow between media and audience and generally discuss the consequences of the “direct audience payment for participation” from the perspective of communication ethics.

    1994-01-01

    We study the problem of a seller who wants to maximize her revenue in situations where the outcome of the sale affects the nature of the future interaction between agents. We model those situations by assuming that an agent that does not acquire the object for sale incurs an externality that may depend both on the identity of the sufferer and on the identity of the final purchaser. We describe an optimal auction that has a unique Nash equilibrium in strictly dominant strategies. We show that: 1) Outside options are endogenously determined in equilibrium. Participation constraints and the ''threats'' in case of non-participation play an important role. 2) An optimizing seller can extract surplus also from buyers that do not obtain the auctioned object. 3) The seller is better off by not selling at all (while obtaining some payments) if externalities are large when compared to the pure profits that buyers achieve if they acquire the object. 4) The revenue-maximizing equilibrium is coalition-proof if buyers cannot organize side payments among themselves.

    Full Text Available Edible insect is appraised by many cultures as delicious and nutritionally beneficial food. In western countries this commodity is not fully appreciated, and the worries about edible insect food safety prevail. Electronic noses can become a simple and cheap way of securing the health safety of food, and they can also become a tool for evaluating the quality of certain commodities. This research is a pilot project of using an electronic nose in edible insect culinary treatment, and this manuscript describes the phases of edible insect culinary treatment and methods of distinguishing mealworm (Tenebrio molitor and giant mealworm (Zophobas morio using simple electronic nose. These species were measured in the live stage, after killing with boiling water, after drying and after inserting into the chocolate.The sensing device was based on the Arduino Mega platform with the ability to store the recorded data on the SD memory card, and with the possibility to communicate via internet. Data analysis shows that even a simple, cheap and portable electronic nose can distinguish between the different steps of culinary treatment (native samples, dried samples, samples enriched with chocolate for cooking and selected species. Another benefit of the electronic nose could be its future introduction into the control mechanisms of food security systems (e.g. HACCP.

    Aims Several states in the U.S. have legalized cannabis for recreational or medical uses. In this context, cannabis edibles have drawn considerable attention after adverse effects were reported. This paper investigates Twitter users’ perceptions concerning edibles and evaluates the association edibles-related tweeting activity and local cannabis legislation. Methods Tweets were collected between May 1 and July 31, 2015, using Twitter API and filtered through the eDrugTrends/Twitris platform. A random sample of geolocated tweets was manually coded to evaluate Twitter users’ perceptions regarding edibles. Raw state proportions of Twitter users mentioning edibles were ajusted relative to the total number of Twitter users per state. Differences in adjusted proportions of Twitter users mentioning edibles between states with different cannabis legislation status were assesed via a permutation test. Results We collected 100,182 tweets mentioning cannabis edibles with 26.9% (n=26,975) containing state-level geolocation. Adjusted percentages of geolocated Twitter users posting about edibles were significantly greater in states that allow recreational and/or medical use of cannabis. The differences were statistically significant. Overall, cannabis edibles were generally positively perceived among Twitter users despite some negative tweets expressing the unreliability of edible consumption linked to variability in effect intensity and duration. Conclusion Our findings suggest that Twitter data analysis is an important tool for epidemiological monitoring of emerging drug use practices and trends. Results tend to indicate greater tweeting activity about cannabis edibles in states where medical THC and/or recreational use are legal. Although the majority of tweets conveyed positive attitudes about cannabis edibles, analysis of experiences expressed in negative tweets confirms the potential adverse effects of edibles and calls for educating edibles-naïve users, improving

    The use of edible insects has a long history in China, where they have been consumed for more than 2000 years. In general, the level of acceptance is high for the consumption of insects in China. Many studies on edible insects have been conducted in the last 20 years, and the scope of the research includes the culture of entomophagy and the identification, nutritional value, farming and breeding of edible insects, in addition to food production and safety. Currently, 324 species of insects from 11 orders are documented that are either edible or associated with entomophagy in China, which include the common edible species, some less commonly consumed species and some medicinal insects. However, only approximately 10 to 20 types of insects are regularly consumed. The nutritional values for 174 species are available in China, including edible, feed and medicinal species. Although the nutritional values vary among species, all the insects examined contain protein, fat, vitamins and minerals at levels that meet human nutritional requirements. Edible insects were, and continue to be, consumed by different ethnic groups in many parts of China. People directly consume insects or food products made from insects. The processing of products from insect protein powder, oil and chitin, and the development of healthcare foods has been studied in China. People also consume insects indirectly by eating livestock that were fed insects, which may be a more acceptable pathway to use insects in human diets. Although limited, the data on the food safety of insects indicate that insects are safe for food or feed. Incidences of allergic reactions after consuming silkworm pupae, cicadas and crickets have been reported in China. Insect farming is a unique breeding industry in rural China and is a source of income for local people. Insects are reared and bred for human food, medicine and animal feed using two approaches in China: the insects are either fully domesticated and reared

  20. Threatened edible insects in Hidalgo, Mexico and some measures to preserve them.

    Ramos-Elorduy, Julieta

    2006-12-04

    Edible insects are a natural renewable resource that provides food to many ethnic groups in Mexico. Some of these species are overexploited because of increased consumption, caused by the huge human population growth in the area and because of the large demand of these insects from many restaurants in Mexico and in other countries. In Tulancalco, a small arid village in the State of Hidalgo, I carried out studies on edible insects over 25 years. The inhabitants of this village have a natural economy and use some 30 species of insects as food. At present, we have noticed a decrease in the population of several species due to overexploitation, which is carried by non-qualified independent workers who are not natives of the town. These gatherers sell their catch to make a living, thus contributing to the socioeconomic factors associated with this issue. These actions have degraded the ecosystems of this area, and consequently the prevention of these measures is critical. The study species in this paper include 14 threatened species and we discuss some pragmatic measures that could implemented to avoid their extinction. In addition, some actions for the preservation of the ethnoentomobiodiversity in the area are proposed.

Cholesterol and three phytosterols (campesterol, stigmasterol and β-sitosterol were reliably identified and quantified after hot saponification and derivatization by GC-MS. Other steroid compounds, including 5,6-trans-cholecalciferol were identified only according to the NIST library. Cholesterol was the predominant sterol in all analysed samples. Both types of larvae also contained high amount of phytosterols. Different region of origin had a no significant impact on sterols composition, while the effect of beetle genus was crucial. Tocopherols were analysed by reverse phase HPLC coupled with amperometric detection. Tocopherols content in mealworm larvae was lower than content in edible oils, but important from the nutritional point of view. Change of tocopherols composition was not observed during the storage under different conditions. Larvae of edible insect can be a potential good dietary source of cholesterol, but also vitamin D3 isomers, phytosterols and tocopherols.

    Demand variability is prevailing in the current rapidly changing business environment, which makes it difficult for a retailer that sells multiple substitutable products to determine the optimal inventory. To combat demand uncertainty, both strategies of inventory substitution and probabilistic selling can be used. Although the two strategies differ in operation, we believe that they share a common feature in combating demand uncertainty by encouraging some customers to give up some specific ...

    Full Text Available The 21st century sustainable city requires the merging of urbanism with sustainable food systems. The challenges industrial food system separates people from their food sources. The design strategies for edible landscape are about re-inviting food back into the city and re-connecting people with their local/regional food system to promote a healthier lifestyle. Edible landscapes are a movement in transition and sprouting up as a response to the slow food movement and living a greener lifestyle. These urban agricultural landscapes are fast becoming iconic media darlings and are demonstrating that they are far more than growing vegetables and fruits on abandoned lots. Edible landscaping is the use of food plants as design features in a landscape. These plants are used both for aesthetic value as well as consumption. Edible landscapes encompass a variety of garden types and scales but do not include food items produced for sale. Edible landscaping is the practical integration of food plants within an ornamental or decorative setting. Using edibles in landscape design can enhance a garden by providing a unique ornamental component with additional health, aesthetic, and economic benefits. In this study; emergence of edible landscape, edible landscape design and maintenance, samples of edible landscape, productive plants, importance of edible landscaping for urban environments have been explained.

    The Sierra Madre Occidental of Chihuahua in Northern Mexico is inhabited by indigenous Raramuris, mestizos, and other ethnic groups. The territory consists of canyons and ravines with pine, oak and pine-oak forests in the higher plateaus. A great diversity of potentially edible mushrooms is found in forests of the Municipalities of Bocoyna and Urique. Their residents are the only consumers of wild mushrooms in the Northern Mexico; they have a long tradition of collecting and eating these during the "rainy season." However, despite the wide diversity of edible mushrooms that grow in these areas, residents have a selective preference. This paper aims to record evidence of the knowledge and use of wild potentially edible mushroom species by inhabitants of towns in the Sierra Tarahumara of Chihuahua, Mexico. Using a semi-structured technique, we surveyed 197 habitants from seven locations in Urique, Bocoyna, and the Cusarare area from 2010 to 2012. Known fungi, local nomenclature, species consumed, preparation methods, appreciation of taste, forms of preservation, criteria for differentiating toxic and edible fungi, other uses, economic aspects, and traditional teaching were recorded. To identify the recognized species, photographic stimuli of 22 local edible species and two toxic species were used. The respondents reported preference for five species: Amanita rubescens, Agaricus campestris, Ustilago maydis, Hypomyces lactifluorum, and the Amanita caesarea complex. No apparent differences were found between ethnic groups in terms of preference, although mestizos used other species in Bocoyna (Boletus edulis and B. pinophilus). Some different uses of fungi are recognized by respondents, i.e. home decorations, medicine, as food in breeding rams, etc. The studied population shows a great appreciation towards five species, mainly the A. caesarea complex, and an apparent lack of knowledge of nearly 20 species which are used as food in other areas of Mexico. There are no

    Full text of publication follows: edible mushrooms play an important role even in modern society - far beyond their value as food supply. The search for and gathering of edible mushrooms is one of the last possibilities of urbanized man to satisfy his drive as a hunter and collector in nature and thus an important part of the cultural heritage. Deprivation of this recreational activity due to radioactive contamination is considered simply a certain loss of quality of life and thus may have a strong emotional and sociological impact. The accident at the Chernobyl reactor on 26 April 1986 led to considerable amounts of radioactive material being distributed over a large area of Europe with Austria as one of the highest contaminated western countries. 13 years after the accident at Chernobyl, the long-lived isotopes such as cesium 137 (physical half-life of 30.2 years) and others are still of concern. Several publications suggest that the consumption of wild growing mushrooms has to be regarded as risky. The aim of our study is to provide some new investigations on the process of accumulation of radioactive Cs in ecosystems with the focus of attention on fungi, Therefore factors and processes limiting isotope accumulation of edible mushrooms are being determined, using standard microbiological and physical methods. Through a series of experiments and evaluations some factors limiting the accumulation of radionuclides in mycelia and in fruit bodies of selected mushrooms with a main emphasis placed on taxonomic position of each species and type of metabolism are being defined. On this basis careful extrapolation to the industrially cultivated species and to the most popular objects amongst mushroom-collectors is to be achieved. Our approach of assessing the risk of radioactive contamination of edible mushrooms, which is applicable for any assumed scenario, will be discussed. (authors)

    In this workshop we describe using Earth and Space Science demonstrations with edible ingredients to increase student interest. We show how to use chocolate, candy, cookies, popcorn, bagels, pastries, Pringles, marshmallows, whipped cream, and Starburst candy for activities such as: plate tectonics, the interior structure of the Earth and Mars, radioactivity/radioactive dating of rocks and stars, formation of the planets, lunar phases, convection, comets, black holes, curvature of space, dark energy, and the expansion of the Universe. In addition to creating an experience that will help students remember specific concepts, edible activities can be used as a formative assessment, providing students with the opportunity to create something that demonstrates their understanding of the model. The students often eat the demonstrations. These demonstrations are an effective teaching tool for all ages, and can be adapted for cultural, culinary, and ethnic differences among the students.

    Full Text Available Land snails are sources of protein to man and are hosts to a number of parasites. It is imperative that the roles of the snail hosts and parasites are clearly defined. Before then however, the parasites of the different land snails collected in any locality should be identified. Land snails were collected in the wild in both dry and wet seasons. The internal organs and the faeces were examined for the presence of parasite. In the rainy season of 2015, a total of 272 snails were collected across four major towns (Benin, Uromi, Ekpoma and Auchi in Edo State, Nigeria, while in the dry season, fewer snails (n=91 were handpicked. The snail species seen are: Achatina achatina (Linnaeus, 1758, Achatina fulica (Férussac, 1821, Acharchatina marginata (Swainson, 1982, Limicolaria aurora (Jay, 1839, L. flammea (Müller, 1774 and Limicolariopsis spp. The larvae of Strongyloides stercoralis were isolated from the various snail species with overall prevalence of 54.04 %. Snails positive with Alaria mesocercariae were L. aurora, L. flammea and Limicolariopsis spp. Additionally, few L. flammea were positive of the cercariae of Drocoelium dedriticum. Meanwhile, some samples of A. fulica harboured larvae of Angiostrongylus cantonesis, sporocysts of Fasciola gigantica and Schistosoma mansoni. Therefore, these edible snails could pose serious health hazard to man and animals by serving as a possible alternative parasite transmission route.

    Full Text Available Edible vaccines hold great promise as a cost-effective, easy-to-administer, easy-to-store, fail-safe and socioculturally readily acceptable vaccine delivery system, especially for the poor developing countries. It involves introduction of selected desired genes into plants and then inducing these altered plants to manufacture the encoded proteins. Introduced as a concept about a decade ago, it has become a reality today. A variety of delivery systems have been developed. Initially thought to be useful only for preventing infectious diseases, it has also found application in prevention of autoimmune diseases, birth control, cancer therapy, etc. Edible vaccines are currently being developed for a number of human and animal diseases. There is growing acceptance of transgenic crops in both industrial and developing countries. Resistance to genetically modified foods may affect the future of edible vaccines. They have passed the major hurdles in the path of an emerging vaccine technology. Various technical obstacles, regulatory and non-scientific challenges, though all seem surmountable, need to be overcome. This review attempts to discuss the current status and future of this new preventive modality.

    Full Text Available The paper discusses the renewed short selling regulation (Regulation (EU No 236/2012 in the European Union. The focus is on the provisions that deal with prohibiting short selling in exceptional market circumstances. The Regulation further enforces certain obligations to report and disclose short positions. It is concluded that banning short selling is not an effective tool to contain extreme price volatility. The difference-in-differences regression and repeated measures GLM were used to test whether short selling bans were successful in containing volatility of those Spanish and Italian stocks that were subject to two back-to-back prohibitions during the years 2011-2013. The results are consistent with the majority of previous research, suggesting that the effectiveness of short sale constraints in reducing volatility is limited at best. Furthermore, there are evidence of counterproductive effects: constraints on short selling may actually increase volatility as well as deteriorate liquidity. However, based on theory and previous studies, reporting and disclosure requirements shall be favored provided they improve market efficiency as well as supervisory work of regulatory bodies.This paper discusses the renewed short selling regulation (Regulation (EU No 236/2012 in the European Union.

    Compared with other types of packaging, edible coatings are becoming more and more popular because of their more environmentally friendly properties and active ingredients carrying ability. The edible coating can reduce the influence of essential oils (EOs) on the flavor of the product and also can prolong the action time of EOs through the slow-release effect, which effectively promote the application of EOs in food. Understanding the different combinations of edible coatings and EOs as well as their antimicrobial effects on different microorganisms will be more powerful and targeted to promote the application of EOs in real food systems. The review focus on the contribution of the combination of EOs and edible coatings (EO-edible coatings) to prolong the shelf life of food products, (1) specifically addressing the main materials used in the preparation of EO-edible coatings and the application of EO-edible coatings in the product, (2) systematically summarizing the main production method of EO-edible coatings, (3) discussing the antiseptic activity of EO-edible coatings on different microorganisms in food.

    The aim of this work was to study the saponin profiles from spears of different wild asparagus species in the context of its genetic diversity aside from geographical seed origin. They included Asparagus pseudoscaber Grecescu, Asparagus maritimus (L.) Mill., Asparagus brachiphyllus Turcz., Asparagus prostrates Dumort., and Asparagus officinalis L. The saponin analysis by LC-MS has shown that saponin profile from wild asparagus is similar to that previously described for triguero asparagus from Huétor-Tájar landrace (triguero HT), which had not ever been reported in the edible part of asparagus. All the samples, except A. officinalis, were characterized for having saponins distinct to protodioscin and the total saponin contents were 10-fold higher than those described for commercial hybrids of green asparagus. In particular, A. maritimus from different origins were rich in saponins previously found in triguero HT. These findings supported previous suggestion, based on genetic analysis, about A. maritimus being the origin of triguero HT. Multivariate statistics including principal component analysis and hierarchical clustering analysis were used to define both similarities and differences among samples. The results showed that the greatest variance of the tested wild asparagus could be attributed to differences in the concentration of particular saponins and this knowledge could be a tool for identifying similar species. © 2017 Institute of Food Technologists®.

    Sales of green power products are booming in Europe: 50,000 customers in the United Kingdom, 775,000 in the Netherlands and 300,000 in Germany. Laws of physics are however formal: the way in which electricity flows within the grid does not allow suppliers to assure customers that they are directly receiving electricity produced exclusively from renewable energy sources. What are marketers selling their customers then? Laetitia Ouillet, Greenprices, takes a closer look and focuses on the potential of selling green energy in the forms of renewable energy certificates.

The aim was to gain an understanding of young women’s perceptions of the reasons they started, continued, and stopped selling sex. The study included interviews with 15 young women between the ages of 15 and 25 (M=18.9. Thematic analysis was used to identify similarities and differences in the narratives. Three themes and eight sub-themes were identified in relation to different stages in their lives in the sex trade. The themes were organized into three parts, each with its own storyline: “Entering – adverse life experiences”; traumatic events: feeling different and being excluded. “Immersion – using the body as a tool for regulating feelings”; being seen: being touched: being in control: affect regulation and self-harming. “Exiting – change or die”; living close to death: the process of quitting. The informants all had stable social lives in the sense that they had roofs over their heads, food to eat, and no substance-abuse issues. None had a third party who arranged the sexual contacts and none were currently trafficked. They described how their experiences of traumatic events and of feeling different and excluded had led them into the sex trade. Selling sex functioned as a way to be seen, to handle traumatic events, and to regulate feelings. Professionals working with young people who sell sex online need to understand the complex web of mixed feelings and emotional needs that can play a role in selling sex. Young people selling sex might need guidance in relationship building as well as help

    2017-08-01

    Full Text Available Introduction: Edible flowers has been used for thousands of years. They increase aesthetic appearance of food, but more often they are mentioned in connection with biologically active substances. The main ingredient of the flowers is water, which accounts for more than 80%. In small amounts, there are also proteins, fat, carbohydrates, fiber and minerals. Bioactive substances such as carotenoids and phenolic compounds determine the functional properties of edible flowers. Aim: The aim of this work was to characterize the phenolic compounds found in edible flowers and compare their antioxidant activity. Results: This review summarizes current knowledge about the usage of edible flowers for human nutrition. The work describes the antioxidant activity and phenolic compounds of some edible flowers. Based on literature data there is a significant difference both in content of phenolic compounds and antioxidant activity between edible flowers. These difference reaches up to 3075-fold in case of antioxidant potential. Among described edible flowers the most distinguishable are roses, peonies, osmanthus fragans and sambuco nero. Conclusions: Edible flowers are the new source of nutraceuticals due to nutritional and antioxidant values.

    Edible insects are ideal food sources, which contain important nutrients and health-promoting compounds. With a rapid development of industrial insect farming, insect-derived food is a novel and emerging food industry. Edible insects have been traditionally consumed in various communities, while continuously gaining relevance in today's society; however, they currently remain underutilized. Although there are a large number of literature on edible insects, these literature primarily focus on the nutritional value edible insects. The toxicity assessment data of edible insects remain incomprehensive, especially for the new national standard that is currently in effect; and many data and conclusions are not accurately specified/reported. Therefore, we performed a literature review and summarized the data on the toxicological assessment of edible insects in China. The review first describes the research progress on safety toxicological assessment, and then offers references regarding the development of 34 edible insect species in China. These data can be a platform for the development of future toxicological assessment strategies, which can be carried out by a multidisciplinary team, possibly consisting of food engineers, agronomists, farmers, and so on, to improve the acceptability of edible insects.

    This study assesses the availability of websites offering to sell psilocybin spores and psilocybin, a powerful hallucinogen contained in Psilocybe mushrooms. Over a 25-month period beginning in March 2003, eight searches were conducted in Google using the term "psilocybin spores." In each search the first 100 nonsponsored links obtained were scored by two independent raters according to standardized criteria to determine whether they offered to sell psilocybin or psilocybin spores. No attempts were made to procure the products offered for sale in order to ascertain whether the marketed psilocybin was in fact "genuine" or "counterfeit." Of the 800 links examined, 58% led to websites offering to sell psilocybin spores. Additionally, evidence that whole Psilocybe mushrooms are offered for sale online was obtained. Psilocybin and psilocybin spores were found to be widely available for sale over the Internet. Online purchase of psilocybin may facilitate illicit use of this potent psychoactive substance. Additional studies are needed to assess whether websites offering to sell psilocybin and psilocybin spores actually deliver their products as advertised.

(2 Will selling on GB websites always be better than staying with offline channel only? (3 What kind of products is more appropriate to sell on GB website? (4How could GB website operator induce sellers to offer deep discount in GB deals? Findings and Originality/value: This paper obtains optimal strategies for sellers selling on GB website and finds that: Even if a seller has sufficient capacity, he/she may still set a maximum deal size on the GB deal to take advantage of Advertisement with Limited Availability (ALA effect; Selling through GB website may not bring a higher profit than selling only through offline channel when a GB site only has a small consumer base and/or if there is a big overlap between the online and offline markets; Low margin products are more suitable for being sold online with ALA strategies (LP-ALA or HP-ALA than high margin ones; A GB site operator could set a small minimum deal size to induce deep discounts from the sellers selling through GB deals. Research limitations/implications: The present study assumed that the demand function is determinate and linear. It will be interesting to study how stochastic demand and a more general demand function affect the optimal

    Edible brown algae have attracted interest as a source of beneficial allenic carotenoid fucoxanthin, and glyco- and phospholipids enriched in polyunsaturated fatty acids. Unlike green algae, brown algae contain no or little phosphatidylserine, possessing an unusual aminophospholipid, phosphatidyl-O-[N-(2-hydroxyethyl) glycine], PHEG, instead. When our routinely used technique of 31 P-NMR analysis of phospholipids was applied to the samples of edible New Zealand brown algae, a number of signals corresponding to unidentified phosphorus-containing compounds were observed in total lipids. NI (negative ion) ESI QToF MS spectra confirmed the presence of more familiar phospholipids, and also suggested the presence of PHEG or its isomers. The structure of PHEG was confirmed by comparison with a synthetic standard. An unusual MS fragmentation pattern that was also observed prompted us to synthesise a number of possible candidates, and was found to follow that of phosphatidylhydroxyethyl methylcarbamate, likely an extraction artefact. An unexpected outcome was the finding of ceramidephosphoinositol that has not been reported previously as occurring in brown algae. An uncommon arsenic-containing phospholipid has also been observed and quantified, and its TLC behaviour studied, along with that of the newly synthesised lipids.

    The depletion of tylosin residues in edible turkey tissues was followed after 3 days of administration of tylosin tartrate at 500 mg l-1 in drinking water, to 30 turkeys. Immediately after the end of the treatment (day 0) and at day 1, 3, 5 and 10 of withdrawal, six turkeys (three males and three females) per time were sacrificed and samples of edible tissues were collected. Tissue homogenates were extracted, purified and analysed by HPLC according to a method previously published for the analysis of tylosin residues in pig tissues. In all tissues, tylosin residues were already below the detection limits of 50 micrograms kg-1 at time zero. However, in several samples of tissues (skin + fat, liver, kidney, muscle), from the six turkeys sacrificed at that time, one peak corresponding to an unknown tylosin equivalent was detected at measurable concentrations. The identification of this unknown compound was performed by LC-MS/MS analysis of the extracts from incurred samples. The mass fragmentation of the compound was consistent with the structure of tylosin D (the alcoholic derivative of tylosin A), the major metabolite of tylosin previously recovered and identified in tissues and/or excreta from treated chickens, cattle and pigs.

    Full Text Available Insects are for many nations and ethnic groups an indispensable part of the diet. From a nutritional point of view, insects have significant protein content. It varies from 20 to 76% of dry matter depending on the type and development stage of the insect. Fat content variability is large (2–50% of dry matter and depends on many factors. Total polyunsaturated fatty acids' content may be up to 70% of total fatty acids. Carbohydrates are represented mainly by chitin, whose content ranges between 2.7 mg and 49.8 mg per kg of fresh matter. Some species of edible insects contain a reasonable amount of minerals (K, Na, Ca, Cu, Fe, Zn, Mn and P as well as vitamins such as B group vitamins, vitamins A, D, E, K, and C. However their content is seasonal and dependent on the feed. From the hygienic point of view it should be pointed out that some insects may produce or contain toxic bioactive compounds. They may also contain residues of pesticides and heavy metals from the ecosystem. Adverse human allergic reactions to edible insects could be also a possible hazard.

    Food products containing cannabis extract (edibles) have emerged as a popular and lucrative facet of the legalized market for both recreational and medicinal cannabis. The many formulations of cannabis extracts used in edibles present a unique regulatory challenge for policy makers. Though edibles are often considered a safe, discreet, and effective means of attaining the therapeutic and/or intoxicating effects of cannabis without exposure to the potentially harmful risks of cannabis smoking, little research has evaluated how ingestion differs from other methods of cannabis administration in terms of therapeutic efficacy, subjective effects, and safety. The most prominent difference between ingestion and inhalation of cannabis extracts is the delayed onset of drug effect with ingestion. Consumers often do not understand this aspect of edible use and may consume a greater than intended amount of drug before the drug has taken effect, often resulting in profoundly adverse effects. Written for the educated layperson and for policy makers, this paper explores the current state of research regarding edibles, highlighting the promises and challenges that edibles present to both users and policy makers, and describes the approaches that four states in which recreational cannabis use is legal have taken regarding regulating edibles.

    Full Text Available This paper addresses the issue of the understanding of the book-selling situation as Swedish booksellers see it. It pursues the answers to the following questions: 1. What are the perceptions of Swedish booksellers of the impact of e-books on their business? 2. What drivers are important for Swedish booksellers for adopting and developing e-book sales through their own sales channels? 3. What do they perceive as barriers to e-book selling through their own channels? The authors have employed the analysis of the secondary statistical data and a survey of Swedish booksellers to answer their questions. The results of the investigation have shown that the Swedish booksellers do not feel their bookshops, or business in general, are threatened by e-books. The opinions on e-books do not differ between the few selling e-books and others who do not offer this product. The reasons for selling e-books are well-functioning routines and personal interest in the product. The reasons for not selling the books are the lack of demand and technical resources as well as contractual agreements with e-book publishers or vendors. So, technical resources for e-book sales, routines, and contracts with publishers are the main premises for this activity. The biggest barriers to e-book sales are: a the price as one can see not only in the answers of the booksellers, but also in the drop of sales obviously related to the rise of prices during 2014; b lack of demand from customers who do not enquire about e-books in bookshops. This leads to the belief that e-books will be sold mostly online either directly from publishers and authors or through online booksellers. However, an equal number of booksellers believe that physical bookshops will be selling printed books and e-books in the future. The future of e-books seems to be quite secure and non-threatening to printed books from the point of view of booksellers. The growth of e-book sales is quite slow and the respondents

    The depletion of tylosin from edible pig tissues was studied following 5 days of intramuscular (i.m.) administration of 10 mg/kg of tylosin to 16 crossbreed pigs. Animals were slaughtered at intervals after treatment and samples of muscle, kidney, liver, skin+fat, and injection site were collected and analysed by high-performance liquid chromatography (HPLC). Seven days after the completion of treatment, the concentration of tylosin in kidney, skin+fat, and at the injection site was higher than the European Union maximal residue limit (MRL) of 100 microg/kg. Tylosin residues in all tissues were below the quantification limit (50 microg/kg) at 10 and 14 days post-treatment.

    The traditional consumption of edible insects is common in one third of the world's population, mostly in Latin America, Africa and Asia. There are over one thousand identified species of insects eaten in some stage of their life cycle; and they play important roles in ensuring food security. The most common way to collect insects are from the wild, which is seasonal with limited availability and has an increasing demand resulting in a disruption to the ecosystem. There is a growing interest shown in rearing insects for commercial purposes, and an industrial scale production will be required to ensure steady supplies. Industrial production will need to take into account the living environment of insects, the nutritional composition of their feed and the overall efficiency of the production system. We provide a short overview on the consumption of and rearing insects in Africa, Asia and Europe. For Africa, a snapshot is given for Nigeria, Ghana, Central African Republic, Kenya and Uganda, while the following countries are reported for Asia: China, Japan, Lao People's Democratic Republic, Thailand and Vietnam. In addition, a list of insect species with the highest potential for food and feed in the European Union is provided with some reference to The Netherlands and Finland. The review concludes that there is need to better understand the rearing and farming procedures that will yield high quality edible insects in Africa, Asia and Europe.

    2014-01-01

    Edible aquatic macrophytes grown in arsenic (As)-contaminated soil and sediment were investigated to determine the extent of As accumulation and potential risk to humans when consumed. Nasturtium officinale (watercress) and Diplazium esculentum (warabi) are two aquatic macrophytes grown and consumed in Hawaii. Neither has been assessed for potential to accumulate As when grown in As-contaminated soil. Some former sugarcane plantation soils in eastern Hawaii have been shown to have concentrations of total As over 500 mg kg(-1). It was hypothesized that both species will accumulate more As in contaminated soils than in non-contaminated soils. N. officinale and D. esculentum were collected in areas with and without As-contaminated soil and sediment. High soil As concentrations averaged 356 mg kg(-1), while low soil As concentrations were 0.75 mg kg(-1). Average N. officinale and D. esculentum total As concentrations were 0.572 mg kg(-1) and 0.075 mg kg(-1), respectively, corresponding to hazard indices of 0.12 and 0.03 for adults. Unlike previous studies where watercress was grown in As-contaminated water, N. officinale did not show properties of a hyperaccumulator, yet plant concentrations in high As areas were more than double those in low As areas. There was a slight correlation between high total As in sediment and soil and total As concentrations in watercress leaves and stems, resulting in a plant uptake factor of 0.010, an order of magnitude higher than previous studies. D. esculentum did not show signs of accumulating As in the edible fiddleheads. Hawaii is unique in having volcanic ash soils with extremely high sorption characteristics of As and P that limit release into groundwater. This study presents a case where soils and sediments were significantly enriched in total As concentration, but the water As concentration was below detection limits. © 2013 Published by Elsevier Inc.

    Full Text Available Sicily has become a food and wine area of great interest. However, conflicts within the supply chains have caused the selling process to become long and complex to the disadvantage of farmers, thereby leading to an information asymmetry between producers and consumers.In order to meet the new needs of the agrifood sector, we developed a theoretical model of organized direct selling that goes beyond regional boundaries, which is an alternative model to farmers’ markets and that helps to promote the creation of a network among the operators of Sicilian agrifood supply chains. The aims of this study was to verify the potential of the proposed theoretical model based on a SWOT analysis, which was achieved by collecting data from interviews with the producers involved in the Sicilian agrifood supply chains, and with the main stakeholders involved.

    The Top Application characteristics Remainder Offer characteristics Tree (TAROT) was first introduced in 2007. This is a modified Classification and Regression Trees (CART) used to help decide which question(s) to ask potential applicants to customise an offer of a personal financial product so that it would have a high probability of take up. In this piece of work the authors are presenting, they have further modified the TAROT to cross TAROT, using its properties and modeling steps to deal with the issue of cross-selling. Since the bank already has ready customers, it would be ideal to cross-sell the financial products seeing that one can ask one (or more) further question(s) based on the initial offer to identify and customise another financial product to offer.

    Full Text Available Of major importance in realizing the potential of edible insects as a core element in improving food security, sustainable food production, and biodiversity conservation, are developments in sustainable exploitation of wild edible insect populations and in (semi-cultivating and farming edible insects. Such developments can draw on both western science and indigenous knowledge. Oecophylla smaragdina Fabricius Hymenoptera: Formicidae, of which particularly the queen brood is commonly consumed in Thailand and the Lao PDR, is believed to have the potential to act as flagship/umbrella species in forest conservation and management, to be incorporated simultaneously as biological control agent and direct source of human food in agroforestry practices, and to be (semi-cultivated. We provide a detailed account of indigenous knowledge of O. smaragdina and ant brood collection practices from the Vientiane Plain, Lao PDR, through focus group discussions and participant observations, and then reflect on sustainability and conservation issues, and on semi-cultivating constraints and possibilities embedded in indigenous knowledge and ant brood collection practices.

    Recent evidence suggests that one-third of women receive information about pregnancy and childbirth through books. Messages about what characteristics are normal (or expected) in childbirth are disseminated in a variety of ways, including popular childbirth education books, but little study of them has been conducted. The purpose of this investigation is to address that gap by examining the discussions about childbirth in the 10 top-selling books in the United States. Discourse analysis (relating to the public, personal, and political discussions about a specific phenomenon) was used to study 10 best-selling United States childbirth advice books marketed to childbearing women during the first week of November 2007. Book styles ranged from clinical descriptions of pregnancy and birth primarily offering reassurance, self-help information, and danger signs to more folksy and humorous commentaries. Presentation of scientific evidence to support recommendations was uneven and at times inaccurate. Five focal areas of discourse included body image, labor and birth, pain, power and control, and life preparation for motherhood. Top-selling books shine an interesting light on the current state of United States maternity practices. Women and health professionals should assess them carefully and engage with each other about their recommendations and implications for childbirth.

    2011-03-01

    A rheological creep test was used to investigate the viscoelastic failure of five edible fats. Butter, spreadable blend and spread were selected as edible fats because they belong to three different groups according to the Codex Alimentarius. Creep curves were analysed according to the Burger model. Results were fitted to a Weibull distribution representing the strain-dependent lifetime of putative fibres in the material. The Weibull shape and scale (lifetime) parameters were estimated for each substance. A comparison of the rheometric measurements of edible fats demonstrated a clear difference between the three different groups. Taken together the results indicate that butter has a lower threshold for mechanical failure than spreadable blend and spread. The observed behaviour of edible fats can be interpreted using a model in which there are two types of bonds between fat crystals; primary bonds that are strong and break irreversibly, and secondary bonds, which are weaker but break and reform reversibly.

    Recent research indicates that marijuana-infused food product (i.e., edible) use is becoming nearly as common as smoking marijuana where medical marijuana is available. This study explores edible use among teens. We conducted four focus groups in the San Francisco Bay Area with youth, ages 15-17. The focus groups were divided by gender and whether they used marijuana. Some teens mentioned edible use at school. Youth reported that teens consume edibles, primarily to reduce the likelihood of getting caught. Edibles are also attractive to those who do not like to smoke or have concerns about smoking. Both male and female respondents suggested that females are more likely than males to prefer edibles over smoking, one reason for which may be to avoid smelling like marijuana smoke. For some young women, edibles may be a way to avoid publicly presenting themselves as marijuana users. Findings also suggest that youth have access to edibles through multiple sources. Youth reported that they can purchase edibles at school from other students who either make the edibles themselves or are reselling edibles obtained from dispensaries. Both users and non-users were aware of potentially negative consequences related to edible use. Some youth mentioned that they have heard of youth dying from edibles, and several reported being concerned about the high produced by edibles. Female non-users appeared to be more concerned than others about edibles and compared them to drinks that could be spiked with drugs. However, sentiment among some male marijuana users was that if you cannot handle edibles you should not be using them. These findings suggest that strategies to curb access to edibles and use among youth, such as restricting sales of edibles with strong youth appeal and educating youth on the risks of edibles, will need to be developed.

    In Ayurveda, Leea macrophylla Roxb. ex Hornem. (Leeaceae) is indicated in worm infestation, dermatopathies, wounds, inflammation, and in symptoms of diabetes. The present study aims to determine the antioxidant and antibacterial potential of ethanolic extract and its different fractions of Leea macrophylla root tubers using phytochemical profiling which is still unexplored. Quantitative estimations of different phytoconstituents along with characterization of ethanol extract using high performance liquid chromatography (HPLC) were performed using chlorogenic acid as a marker compound for the first time. The extract and its successive fractions were also evaluated for in vitro antioxidant activity using different models. The extract was further tested against a few Gram-positive and Gram-negative bacteria for its antibacterial activity. Phytochemical screening and quantitative estimations revealed the extract to be rich in alkaloid, flavonoid, phenols, and tannins, whereas chlorogenic acid quantified by HPLC in ethanol extract was 9.01% w/w. The results also indicated potential antioxidant and antibacterial activity, which was more prominent in the extract followed by its butanol fraction. Copyright © 2016. Published by Elsevier B.V.

    Full Text Available Three major herds of wild reindeer (Rangifer tarandus tarandus L., totaling over 200,000 animals, occur in the tundra and taiga of northern Yakutia. These herds have been expanding since the late 1950s and now occupy most of their historic range. In addition, several thousand wild reindeer occupy the New Siberian Islands and adjacent coastal mainland tundra, and there are about 60,000 largely sedentary forest reindeer in mountainous areas of the southern two-thirds of the province. Wild reindeer are commercially hunted throughout the mainland, and the production of wild meat is an important part of the economy of the province and of individual reindeer enterprises which produce both wild and domestic meat.

    Full Text Available Banana peel is a waste of banana processing industries which is obviously uneconomy and unfriendly to the environment. However, this material could be used as a source of important natural compounds, such as pectin. Owing to the fact that pectin has good gelling properties, it can be used to make edible film. The objectives of this research were to extract and characterize pectin from banana peel and to make edible film from the obtained pectin by using glycerol as plasticizer. Characterization of edible films were conducted in terms of color, thickness, elongation, tensile strength and water vapor transmission. The research used factorial completely randomized design. The results showed that yield of pectin made from ambon banana peel ripeness level one was 8.42% with the characteristics werewater content : 11.27% (<12%, ash content : 1.70%, low methoxil content : 4.15% (<7% and galacturonat content : 25.86% (65%. The addition of glycerol significantly increased elongation and decreased tensile strength of edible film. Based on edible film result, the recomended treatment is the addition with glycerol 20% as plasticizer of pectin based edible film.

    Dessert and cooking bananas are vegetatively propagated crops of great importance for both the subsistence and the livelihood of people in developing countries. A wide diversity of diploid and triploid cultivars including AA, AB, AS, AT, AAA, AAB, ABB, AAS and AAT genomic constitutions exists. Within each of this genome groups, cultivars are classified into subgroups that are reported to correspond to varieties clonally derived from each other after a single sexual event. The number of those founding events at the basis of the diversity of bananas is a matter of debate. We analysed a large panel of 575 accessions, 94 wild relatives and 481 cultivated accessions belonging to the section Musa with a set of 498 DArT markers previously developed. DArT appeared successful and accurate to describe Musa diversity and help in the resolution of cultivated banana genome constitution and taxonomy, and highlighted discrepancies in the acknowledged classification of some accessions. This study also argues for at least two centres of domestication corresponding to South-East Asia and New Guinea, respectively. Banana domestication in New Guinea probably followed different schemes that those previously reported where hybridization underpins the emergence of edible banana. In addition, our results suggest that not all wild ancestors of bananas are known, especially in M. acuminata subspecies. We also estimate the extent of the two consecutive bottlenecks in edible bananas by evaluating the number of sexual founding events underlying our sets of edible diploids and triploids, respectively. The attribution of clone identity to each sample of the sets allowed the detection of subgroups represented by several sets of clones. Although morphological characterization of some of the accessions is needed to correct potentially erroneous classifications, some of the subgroups seem polyclonal. © The Author 2016.

    Bisphenol A (BPA) is a man-made compound, mainly used as a monomer to produce polycarbonate (PC), epoxy resins, non-polymer additives to other plastics, which have many food related applications, such as food storage containers, tableware and internal coating of cans, as well as non-food applications such as electronic equipment, construction materials and medical devices. BPA exposure can occur when the residual monomer migrates into packaged food and beverages. Moreover, due to the ubiquitous presence of this compound, the general population can be exposed to environmental sources such as water, air and soil. Many studies have investigated the potential health hazards associated with BPA, which can elicit toxic and cancerogenic effects on humans. According to the European Food Safety Authority opinion, diet is considered to be the main source of exposure, especially canned food; moreover, among non-canned food, meat and fish products have the highest levels of BPA contamination. This review focuses on BPA contamination in seafood, analysing worldwide literature (from January 2010 to October 2015) on BPA contamination of edible parts. The authors try to identify differences between canned and non-canned seafood in literature, and gaps in the state of art. The data evaluated underline that all concentrations for both canned and non-canned seafood were below the specific migration limit set by the European Community Directive for BPA in food. Moreover, the canned seafood is more contaminated than the non-canned one. PMID:27800447

    Antioxidants have been used as radioprotectors in cosmetics and radiation therapy to protect normal tissues in cancer patients. The objective of this study is to determine the activities of antioxidants in Thai edible plants (holy basil, sesame (white and black). durian (Chanee and Monthong), parsley, morning glory, guava, chilies, pepper, sweet pepper, ash pumpkin, pumpkin, tomato, peppermint, and sweet basil) by using I, I-diphenyl-2-picryl-hydrazyl radical and to determine their capability to inhibit radiation-induced hemolysis. Gamma rays (10 KGy) from cobalt-60 was used to induce hemolysis of human red blood cells, and ascorbic acid was used as standard antioxidant. The extracts from all samples showed antioxidant activities. However, only the extracts (0.1-1,000 μg/8 x 10 9 red blood cells) from parsley, guava, peppermint, and sweet basil could significantly inhibit (p<0.05) radiation-induced hemolysis. Although ascorbic acid is a strong antioxidant, its ability to inhibit radiation-induced hemolysis was lower than the extracts. This maybe due to its hydrophilic property which limits its ability to penetrate cell membrane

    2010-01-01

    We present a method to incorporate dishonesty in online selling via a stochastic optimal control problem. In our framework, the seller wishes to maximize her average wealth level W at a fixed time T of her choosing. The corresponding Hamilton-Jacobi-Bellmann (HJB) equation is analyzed for a basic case. For more general models, the admissible control set is restricted to a jump process that switches between extreme values. We propose a new approach, where the optimal control problem is reduced to a multivariable optimization problem.

    2014-01-01

    Background The ethnobotany of Tibetans is a seriously under-studied topic. The aim of the study was to investigate knowledge and use of wild food plants in a valley inhabited by Tibetans in the Gannan Tibetan Autonomous Region. Methods The field research was carried out in a wooded mountain valley in 9 neighbouring villages the Zhouqu (Brugchu) county, and comprised 17 interviews with single informants and 14 group interviews, involving 122 people altogether. Results We recorded the use of 81 species of vascular plants from 41 families. Fruits formed the largest category, with 42 species, larger than the wild greens category, with 36 species. We also recorded the culinary use of 5 species of edible flowers, 7 species with underground edible organs and 5 taxa of fungi. On average, 16.2 edible taxa were listed per interview (median – 16). Green vegetables formed the largest category of wild foods (mean – 8.7 species, median – 9 species), but fruits were listed nearly as frequently (mean – 6.9, median – 6). Other categories were rarely mentioned: flowers (mean – 0.2, median – 0), underground edible parts (mean – 0.3, median – 0) and mushrooms (mean – 1.5, – median 1). Wild vegetables are usually boiled and/or fried and served as side-dishes (cai). They are often lacto-fermented. Wild fruits are mainly collected by children and eaten raw, they are not stored for further use. The most widely used wild vegetables are: Eleuterococcus spp., Pteridium aquilinum, Helwingia japonica, Aralia chinensis, Allium victorialis, Pteridium aquilinum, Ixeris chinensis, Thlaspi arvense and Chenopodium album. The culinary use of Caltha palustris as a green vegetable is very interesting. In its raw state, marsh marigold is a toxic plant, due to the presence of protoanemonin. In this area it is dried or lactofermented before use. The most commonly eaten fruits are: Pyrus xerophila, Prunus salicina, Berchemia sinica, Rubus spp. and Eleagnus umbellata. Conclusions The

    Edible marijuana products have become extremely popular in states that have legalized marijuana for recreational use. The goal of this research was to provide a better understanding of consumer perceptions of edible marijuana products, including why they prefer edibles relative to other forms of marijuana (e.g., smoking) and their concerns regarding the consumption of edibles. We conducted eight focus groups (four groups in Denver, Colorado, and four groups in Seattle, Washington) in February 2016 with 62 adult consumers of edibles. Focus group transcripts were coded in QSR NVivo 10.0 qualitative analysis software, and coding reports identified trends across participants. Most participants preferred edibles to smoking marijuana because there is no smell from smoke and no secondhand smoke. Other reasons participants like edibles included convenience, discreetness, longer-lasting highs, less intense highs, and edibles' ability to aid in relaxation and reduce anxiety more so than smoking marijuana. Concerns and dislikes about edibles included delayed effects, unexpected highs, the unpredictability of the high, and inconsistency of distribution of marijuana in the product. No participants in either location mentioned harmful health effects from consuming edibles as a concern. Conclusions/Importance: The present study was qualitative in nature and provides a good starting point for further research to quantify through surveys how consumers understand and use edibles. Such information will help guide policy makers and regulators as they establish regulations for edibles. Also, such research can help inform educational campaigns on proper use of edibles for recreational purposes.

    2018-01-01

    The expected future demand for food and animal-derived protein will require environment-friendly novel food sources with high nutritional value. Insects may be one of such novel food sources. However, there needs to be an assessment of the risks associated with their consumption, including allergic risks. Therefore, we performed a systematic review aiming to analyse current data available regarding the allergic risks of consuming insects. We reviewed all reported cases of food allergy to insects, and studied the possibility of cross-reactivity and co-sensitisation between edible insects, crustaceans and house dust mites. We analysed a total of 25 articles - eight assessing the cross-reactivity/co-sensitisation between edible insects, crustaceans and house dust mites; three characterizing allergens in edible insects and 14 case reports, describing case series or prevalence studies of food allergy caused by insects. Cross-reactivity/co-sensitisation between edible insects and crustaceans seems to be clinically relevant, while it is still unknown if co-sensitisation between house dust mites and edible insects can lead to a food allergy. Additionally, more information is also needed about the molecular mechanisms underlying food allergy to insects, although current data suggest that an important role is played by arthropod pan-allergens such as tropomyosin or arginine kinase. © 2017 WILEY-VCH Verlag GmbH & Co.

    Turmeric oil (TO) has been studied for its potential as an antioxidation agent in starch edible coating for fresh cut apples and its degree of oxidation was analysed. TO incorporate with starch edible coating was examined using FT-IR Spectroscopy to determine the presence of secondary metabolites. The presence of alcohol and aromatic ring in the edible coating film proved that the secondary metabolites from TO were existed. The fresh cut apples were underwent the sensory test and six out of ten panellist concluded that coated fresh cut apples have good appearance and surface colour. Fresh cut apples were coated with edible coating incorporated with different concentrations of TO (uncoated, 0μL, 5μL, 10μL, 15μL. Percentage weight loss for 15μL were the least which were 1.98% (day 6) and 3.95% (day 12). Colour measurement were done for few days and it shows that the total colour difference (ΔΕ) for 15μL were the lowest. Thus, the oxidation activities for 15μL is the slowest compared to the others. These can be proved through the degree of oxidation analysis using UV-Vis spectroscopy. Uncoated fresh cut apples have the highest degree of oxidation while those with 15μL have the lowest. This study can be illustrated that the oxidation activities of fresh cut apples could be postponed using edible film incorporated with TO.

    Full Text Available In order to extend product shelf life while preserving the quality scientific attention focused to biopolymers research that are base for edible films and coatings production. Another major advantage of this kind of food packaging is their eco-friendly status because biopolymers do not cause environmental problems as packaging materials derived from non-renewable energy sources do. Objective of this work was to review recently studied edible films and coatings - their sources, properties and possible application. As sources for edible biopolymers were highlighted polysaccharides, proteins and lipids. The most characteristic subgroups from each large group of compounds were selected and described regarding possible physical and mechanical protection; migration, permeation, and barrier functions. The most important biopolymers characteristic is possibility to act as active substance carriers and to provide controlled release. In order to achieve active packaging functions emulsifiers, antioxidants and antimicrobial agents can also be incorporated into film-forming solutions in order to protect food products from oxidation and microbial spoilage, resulting in quality improvement and enhanced safety. The specific application where edible films and coatings have potential to replace some traditional polymer packaging are explained. It can be concluded that edible films and coatings must be chosen for food packaging purpose according to specific applications, the types of food products, and the major mechanisms of quality deterioration.

    Full Text Available Abstract Carolus Linnaeus was totally unacquainted with the Edible Dormouse Myoxus glis (L., a species not found in Sweden: while describing Mus Rattus in the 10th Edition of the "Systema Naturae" (1758, the Swedish naturalist confessed his ignorance concerning the "Glis" of the ancients and suggested that it might have been the marmot or the hamster. Thanks to written information received from his correspondent in Slovenia, Giovanni Antonio Scopoli, Linnaeus was able to include the new species Sciurus Glis in his 12th Edition of the "Systema Naturae" (1766, reporting almost verbatim a summary of Scopoli's description of the rodent. Scopoli's letter is still preserved in the Library of the Linnean Society of London. The Linnean type locality "Habitat in Europa australi" for the Edible Dormouse Myoxus glis glis must therefore be restricted to "Southern Carniola, Slovenia", contra "Germany" as stated, for instance, by Miller (1912, Toschi (1965, Corbet (1978 and Storch (1978. A new name is required for the continental European form, for which M. glis germanicus ssp. nov. is here proposed. Some information on the appreciation of Myoxus glis as a delicacy ("carnes avide eduntur" in Linnaeus' words conclude the paper. Riassunto Carlo Linneo ed il Ghiro - Dopo aver descritto Mus Rattus nella decima edizione del "Systema Naturae" (1758 il naturalista svedese Carlo Linneo confessava di non essere a conoscenza del "Glis" degli antichi autori e ne suggeriva l'identificazione con la Marmotta o con il Criceto comune; è infatti noto che Myoxus glis non è diffuso in Svezia.

To assess the current situation, the focus was put to answer the following questions : - Is it feasible under the present circumstances to domesticate these snails with the aim to conserve the natural resources ? - Could any individual or private initiative be enhanced or utilized ? - Would local disadvantaged groups (traditional animal farmers, women oryouths be benefitted through domestication of these snails ? - Is there any existing private organisation or NGO, which already gathers and trades the snails or would be interested to do this in the future ? Snails gatherers, -dealers and -farmers were visited and interviewed on the following topics using standardised questionnaires : Spreading and ecology ways of marketing, consumption habits, breeding and rearing. Diotopes were also visited and investigated. Results Spreading and ecology : Achatina fulica, Pomacea canaliculata, Pila ampullacea and Bellamia javanica are eaten. The snails can be found ail overJava. Ways of marketing : The snails gathered in the biotope are either marketed directly or through various marketing paths. A. fulica is exported in large quantifies. The population is therefore endangered. Consumption habits : Snails are not eaten regularly. Snail meat is known to be healthy. The consumption depends on the consumer's ethnie background. Breeding and rearing experience : with simple breeding systems for A. fulica and P. canaliculata are seldom found. The breeding of P. canaliculata is forbidden in Indonesia. There is no interest in breeding P. ampullacea or B. javanica. The breeding of A. fulica can ben-efit disadvantaged groups financially and help to conserving the natural snail population.

This paper reviews the more recent literature on the incorporation of antioxidants from several sources into films and edible coatings, for application in fruits and vegetables. The use of synthetic antioxidants in foods has been avoided due to their possible toxic effects. Instead, a wide range of natural antioxidants (such as essential oils and plant extracts, as well as pure compounds, like ascorbic acid and α-tocopherol have been incorporated into edible films and coatings to improve their bioactive properties. Films and coatings containing added antioxidants help to preserve or enhance the sensory properties of foods and add value to the food products by increasing their shelf life.

  1. Cultivation of Pleurotus ostreatus and other edible mushrooms.

    2010-02-01

    Pleurotus ostreatus is the second most cultivated edible mushroom worldwide after Agaricus bisporus. It has economic and ecological values and medicinal properties. Mushroom culture has moved toward diversification with the production of other mushrooms. Edible mushrooms are able to colonize and degrade a large variety of lignocellulosic substrates and other wastes which are produced primarily through the activities of the agricultural, forest, and food-processing industries. Particularly, P. ostreatus requires a shorter growth time in comparison to other edible mushrooms. The substrate used for their cultivation does not require sterilization, only pasteurization, which is less expensive. Growing oyster mushrooms convert a high percentage of the substrate to fruiting bodies, increasing profitability. P. ostreatus demands few environmental controls, and their fruiting bodies are not often attacked by diseases and pests, and they can be cultivated in a simple and cheap way. All this makes P. ostreatus cultivation an excellent alternative for production of mushrooms when compared to other mushrooms.

    We study the cross-correlations of buy and sell volumes on the Korean stock market in high frequency. We observe that the pulling effects of volumes are as small as that of returns. The properties of the correlations of buy and sell volumes differ. They are explained by the degree of synchronization of stock volumes. Further, the pulling effects on the minimal spanning tree are studied. In minimal spanning trees with directed links, the large pulling effects are clustered at the center, not uniformly distributed. The Epps effect of buy and sell volumes are observed. The reversal of the cross-correlations of buy and sell volumes is also detected.

    Full Text Available Calcium is one of the most problematic substances in human nutrition. Nutrition in the present population is not optimal, because of insufficient consumption of milk and dairy products. Due to the expanding interest of specialists and the general public about entomophagy, as well as increase of the EU interest in this type of food, there is a need to consider the use of edible insects as an alternative source of nutrition. From the perspective of edible insects as a source of calcium, edible insects could be considered as a possible source of calcium for enriching the diet and also as a substitute for people with lactose intolerance and allergies to other categories of foods rich in calcium. Of the six analysed species of edible insect, Bombyx mori had the highest calcium content, almost comparable to semi-skimmed cow's milk. Gryllus assimillis can also be a rich source of calcium as well as other analysed species. The lowest content of calcium was detected in Zophobas morio. Common meat (chicken, beef, pork has lower calcium content comparing with all analysed species of edible insect (Apis mellifera, Bombyx mori, Gryllus assimillis, Locusta migratoria, Tenebrio molitor, Zophobas morio. Therefore, the selected species of edible insect could serve as an alternative source of calcium for people with lactose intolerance and allergies to soy. Phosphorus level in human body is closely related to calcium in the calcium-phosphate metabolism, therefore phosphorus level was detected in these samples too. Bombyx mori had the highest phosphorus content and the lowest content of phosphorus was measured in Zophobas morio samples.

    2014-08-01

    Full Text Available This study was conducted in 2010 in Eastern Nuba Mountains, Sudan to investigate ethnobotanical food and non-food uses of 16 wild edible fruit producing trees. Quantitative and qualitative information was collected from 105 individuals distributed in 7 villages using a semi-structured questionnaire. Also gathering of data was done using a number of rapid rural appraisal techniques, including key informant interviews, group discussion, secondary data sources and direct observations. Data was analysed using fidelity level and informant consensus factor methods to reveal the cultural importance of species and use category. Utilizations for timber products were found of most community importance than food usages, especially during cultivated food abundance. Balanites aegyptiaca, Ziziphus spina-christi and Tamarindus indica fruits were asserted as most preferable over the others and of high marketability in most of the study sites. Harvesting for timber-based utilizations in addition to agricultural expansion and overgrazing were the principal threats to wild edible food producing trees in the area. The on and off prevailing armed conflict in the area make it crucial to conserve wild food trees which usually play a more significant role in securing food supply during emergency times, especially in times of famine and wars. Increasing the awareness of population on importance of wild food trees and securing alternative income sources, other than wood products, is necessary in any rural development programme aiming at securing food and sustaining its resources in the area.

    During food emulsification and processing of sunflower oil (most used edible oil), a metallic and rancid odour has been detected only for insonated oil and foods. Some off-flavour compounds (hexanal and hept-2-enal) resulting from the sono-degradation of sunflower oil have been identified. A wide variety of analytical techniques (GC determination of fatty acids, UV spectroscopy, free fatty acids and GC/MS) were used to follow the quality of insonated sunflower oil and emulsion. Different edible oils (olive, sunflower, soybean, em leader ) show significant changes in their composition (chemical and flavour) due to ultrasound treatment.

    2000-01-01

    The liberalization of the natural gas market in Europe has all kinds of juridical aspects. Not only with respect to new legislation (Natural Gas Law and Mining Law), but also changes in juridical structures of natural gas companies, caused by privatization or splitting up in a mains management company and a distribution company. In a series of articles lawyers of the Energy Working Group of Houthoff Buruma in The Hague, Netherlands, discuss the developments at the natural gas market. In this third part, attention will be paid to how authorities involved (municipalities, provinces) can prepare themselves properly with respect to selling the gas company and how they can retain their influence on the future activities of the gas company using legal and contractual agreements. In the article also attention is paid to the various stages of a sale

    Two court cases that involve selling prescription data for pharmaceutical marketing affect biomedical informatics, patient and clinician privacy, and regulation. Sorrell v. IMS Health Inc. et al. in the United States and R v. Department of Health, Ex Parte Source Informatics Ltd. in the United Kingdom concern privacy and health data protection, data de-identification and reidentification, drug detailing (marketing), commercial benefit from the required disclosure of personal information, clinician privacy and the duty of confidentiality, beneficial and unsavory uses of health data, regulating health technologies, and considering data as speech. Individuals should, at the very least, be aware of how data about them are collected and used. Taking account of how those data are used is needed so societal norms and law evolve ethically as new technologies affect health data privacy and protection.

    Nuclear Electric, the state-owned company that operates nuclear power stations in England and Wales, has applied to compete directly with privatized electricity generating companies in the sale of electricity to major customers. Since its formation in 1990, NE has had to sell all of its electrical output through the so-called pool operated by the National Grid Company, and then to 12 regional distribution companies that have franchises for about 75 percent of electricity consumption in their regions. On the other hand, the two large companies that took over the fossil-fuel power stations at the time of privatization, and other new independent companies that are building combined-cycle gas-turbine plants, are allowed to conclude supply contracts directly with large industrial customers

    2014-01-01

    Based on our experience in representing more than 100 doctors and medical specialists in practice sales and acquisitions, we have identified 11 key considerations important to a deal. There are several issues to consider while going through the process of buying or selling a practice including the implementation of a "letter of intent" as a first step rather than drafting a contract, securing a lease, and verifying the property is not in violation of the local zoning requirements. There are also considerations with regard to the patients, which range from how will the accounts receivable at the time of the closing be handled to who is responsible for the handling of continued treatment in an ongoing case after a deal is finalized. This article details these considerations and more.

    To analyze the main fatty acids in edible marine fish from Zhoushan, Zhejiang province. From September to October 2011, a total of 186 edible marine fish (31 species,6 individual fishes/species) were collected in local markets. Total lipids of edible part were extracted by Folch's method and fatty acids were separated and quantified by gas chromatographic after the homogenization of edible part. The differences of composition of n-6 polyunsaturated fatty acid (n-6 PUFA), n-3 polyunsaturated fatty acid (n-3 PUFA),saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA) among fishes were analyzed. Among the 31 fishes, total lipids were highest in Auxis thazard ((13.2 ± 1.2)g/100 g edible part) and lowest in Thamnaconus modestus ((0.6 ± 0.1)g/100 g edible part). Total n-6 PUFA were highest in Mugil cephalus ((875.7 ± 506.4)mg/100 g edible part) and lowest in Seriola quinqueradiata((2.1 ± 1.9)mg/100 g edible part). Total n-3 PUFA were highest in Auxis thazard ((2623.8 ± 426.1)mg/100 g edible part) and lowest in Scoliodon sorrakowah ((82.0 ± 13.9)mg/100 g edible part). SFA were highest in Trachinotus ovatus((3014.9 ± 379.0)mg/100 g edible part) and lowest in Seriola quinqueradiata ((89.7 ± 5.8)mg/100 g edible part). MUFA were highest in Coilia nasus ((3335.7 ± 383.5)mg/100 g edible part) and lowest in Thamnaconus modestus ((32.1 ± 16.9)mg/100 g edible part). There were significant differences of composition of total lipids and of fatty acids among 31 edible marine fish species from Zhoushan.

    The ESO Diffuse Interstellar Band Large Exploration Survey (EDIBLES) is a Large Programme that is collecting high-signal-to-noise (S/N) spectra with UVES of a large sample of O and B-type stars covering a large spectral range. The goal of the programme is to extract a unique sample of high-quality interstellar spectra from these data, representing different physical and chemical environments, and to characterise these environments in great detail. An important component of interstellar spectra is the diffuse interstellar bands (DIBs), a set of hundreds of unidentified interstellar absorption lines. With the detailed line-of-sight information and the high-quality spectra, EDIBLES will derive strong constraints on the potential DIB carrier molecules. EDIBLES will thus guide the laboratory experiments necessary to identify these interstellar “mystery molecules”, and turn DIBs into powerful diagnostics of their environments in our Milky Way Galaxy and beyond. We present some preliminary results showing the unique capabilities of the EDIBLES programme.

    Full Text Available Many of the most nutritionally and economically important edible insects are those that are harvested from existing agricultural systems. Current strategies of agricultural intensification focus predominantly on increasing crop yields, with no or little consideration of the repercussions this may have for the additional harvest and ecology of accompanying food insects. Yet such insects provide many valuable ecosystem services, and their sustainable management could be crucial to ensuring future food security. This review considers the multiple ecosystem services provided by edible insects in existing agricultural systems worldwide. Directly and indirectly, edible insects contribute to all four categories of ecosystem services as outlined by the Millennium Ecosystem Services definition: provisioning, regulating, maintaining, and cultural services. They are also responsible for ecosystem disservices, most notably significant crop damage. We argue that it is crucial for decision-makers to evaluate the costs and benefits of the presence of food insects in agricultural systems. We recommend that a key priority for further research is the quantification of the economic and environmental contribution of services and disservices from edible insects in agricultural systems.

    2017-03-01

    Interfacial tension between edible oil and saline was measured under applied electric fields to understand the electrocapillary phenomena at the edible oil/saline interfaces. The electric responses of saline droplets in edible oil were also observed microscopically to examine the relationship between the electrocapillary phenomena and interfacial polarization. When sodium oleate (SO) was added to edible oil (SO-oil), the interfacial tension between SO-oil and saline decreased. However, no decrease was observed for additive-free oil or oleic acid (OA)-added oil (OA-oil). Microscopic observations suggested that the magnitude of interfacial polarization increased in the order of additive-free oil oil oil. The difference in electrocapillary phenomena between OA- and SO-oils was closely related to the polarization magnitude. In the case of SO-oil, the decrease in interfacial tension was remarkably larger for saline (pH 5.4~5.6) than that for phosphate-buffered saline (PBS, pH 7.2~7.4). However, no difference was observed between the electric responses of PBS and saline droplets in SO-oil. The difference in electrocapillary phenomena for PBS and saline could not be simply explained in terms of polarization magnitude. The ratio of ionized and non-ionized OA at the interfaces changed with the saline pH, possibly leading to the above difference.

    Full Text Available The main aim of the present paper is to find out whether the addition of essential oils determines better oxidation stability and positive change of sensory and hedonic perception of edible oils. The oxidation stability of sunflower, corn and grape seed oils was analyzed in the presence of antioxidants in essential oils of rosemary (Rosmarinus officinalis, thyme (Thymus vulgaris and basil (Ocimum basilicum during storage, under conditions of accelerated oxidative processes (4 days, at 60 °C. The total phenolic compounds of these essential oils were determined by the Folin-Ciocalteu method. The DPPH method was used to evaluate the antioxidant capacity of basil, rosemary and thyme essential oils in comparison with known synthetic antioxidant L(+-ascorbic acid. The addition of essential oils to edible oils, the amounts proposed in analyses, determines a favorable influence on their oxidation stability as well as their taste. The influence of addition of essential oils on the taste of edible oils was studied in two products consumed mainly at breakfast, bread and spinach leaves. The results recommend the use of these plant extracts as additives in edible oils rather than synthetic antioxidants.

    Full Text Available In today’s marketing era, consumers seem to have known about marketed products and no longer need explanation from a salesperson. The interaction between company and target consumers can be marketed through new media such as email, Facebook, WA, Instagram, and other forms. Such situations need to be in-depth researched in terms of whether personal selling contribution is still needed in marketing communication activities. Considering the uniqueness and personal selling advantages turns out that personal selling is an important partner that can not be replaced by other forms of marketing communications even if there is exposure to new media to promote products. The specialty of personal selling lies in its ability to interact directly to improvise the sales process through person to person communication. Dalam era pemasaran masa kini nampaknya konsumen dianggap sudah mengetahui tentang produk yang dipasarkan dan tidak memerlukan lagi penjelasan dari seorang wiraniaga. Interaksi perusahaan dengan pembeli sasaran dapat dilakukan melalui media baru seperti email, facebook, WA, instagram dan bentuk lainnya. Situasi demikianlah yang memerlukan kajian mendalam dalam kaitannya bagaimana peran personal selling dalam kegiatan komunikasi pemasaran di era digital? Memperhatikan keunikan dan kelebihan personal selling ternyata personal selling merupakan mitra penting yang tidak dapat tergantikan oleh bentuk komunikasi pemasaran lainnya sekalipun ada terpaan media baru untuk mempromosikan produk. Keistimewaan personal selling terletak pada kemampuannya untuk berinteraksi secara langsung untuk mengimprovisasi proses penjualan melalui komunikasi person to person.

  5. An intervention to reduce the number of convenience stores selling tobacco: feasibility study.

    2016-05-01

    Reduction of the availability of tobacco has been proposed as a means of reducing and denormalising tobacco use. Some retailers have stopped selling tobacco. Therefore, we investigated how willing New Zealand convenience store owners were to stop selling tobacco or sell nicotine replacement therapy. Promotion of their stores was offered as an incentive to stop selling tobacco. We asked convenience store owners in the Auckland metropolitan region of New Zealand to choose one of three actions. The first was to stop selling tobacco for a short period of time; the second was to restrict the hours that they sold tobacco; the third was to display and sell nicotine replacement therapy. All participating retailers completed a short interview about selling tobacco. We also surveyed customers about nicotine replacement and cessation. One-third of eligible retailers agreed to participate. Most who participated (93%) were unwilling to stop or restrict tobacco sales and 2 (7%) had already stopped selling tobacco. Tobacco was perceived as a key product for their businesses. Very few customers who purchased cigarettes noticed nicotine replacement therapy or obtained it from convenience stores. Substantially reducing the availability of tobacco in communities is likely to require legislative approaches, underpinned by sustained community pressure and support for convenience store owners who are willing to change their business model.

  10. Factors Associated With American Indian and White Adolescent Drug Selling in Rural Communities

    Eitle, David; Eitle, Tamela McNulty

    2014-01-01

    Relatively few studies have examined the correlates of adolescent drug selling in America, with most of these studies focusing on urban settings. The present study examines the risk and protective factors associated with drug selling among American Indian and white adolescents residing in a rural Northwestern state in the United States. Using survey data collected in 2010-2012, we conduct logistic regression analyses exploring the correlates of drug selling (n=568). Generally, we found support for prior explanations of drug selling, but identified some important race-specific differences. Specifically, we found that stress exposure was a risk factor for American Indians, but not whites. Conversely, academic achievement served as a protective factor for white adolescents but not American Indians. Our findings suggest that the race gap in rural drug selling can be explained by considering differences in social bonds, stress exposure, and exposure to substance using family and friends.

  11. Radioactive contamination of wild mushrooms: mycological approach and risk perception

    International Nuclear Information System (INIS)

    Droujinina, I.

    2001-11-01

    Recent investigations of the wide range of polluted environments have proven that different toxic elements, especially long-lived radionuclides of caesium and strontium, can be accumulated in fruit bodies of fungi. Therefore, consumption of wild mushrooms can be regarded as a risky activity. Radiocaesium, which was released into the environment by atomic weapons testing and accidents in the nuclear industry, is now accumulated particularly in the upper, mainly organic horizons of forest soils and it is assumed that fungal mycelium play a substantial role for the retention of this pollutant in top layers of soil. Nowadays macromycete fungi become a key point of the forest radioecology because of the extremely high level of the inter- and intraspecific variability of the radionuclide accumulation (from two to four orders of magnitude). The latter significantly complicates all efforts to predict the future migration of radionuclides in the ecosystem and creates a high uncertainty in the radioecological models. At the same time, mechanisms of radiocaesium uptake by fungal mycelium remain poorly understood. In this work, physiological mechanisms of radiocaesium accumulation by fungal mycelium (complex in vitro mycological approach) were investigated along with the pilot sociological study of the perception of the contamination of wild edible mushrooms by citizens of different countries. Such bilateral approach allows the comparison of an expert's perception of the problem with the mental model of those people who consume wild mushrooms. The revealed difference should be useful in future risk communication efforts when interested population should be informed. (author)

  12. Selling gas, selling services

    1999-01-01

    Traditionally, the commercial activities of gas companies have been limited almost exclusively to the sale of gas. However, several socioeconomic factors specific to the gas industry, such as increasing customer expectations, competition between gas operators, a growing emphasis on services in many companies and the opening of public monopolies to competition, will bring inevitable change. Moreover, these developments coincide with imminent gas market opening. In response to the changing situation, the gas industry will seek to develop a range of multi-service offers, probably through external partnerships. (authors)

    The aim of this study was to determine the effects of castration and age on the content of edible and non-edible components, and the distribution of tissue components in the carcasses of cockerels and capons. The study was conducted on 200 birds (Green-legged Partridge), divided into two sex categories (with 5 replications per group and 20 birds per replication), raised to 28 wk of age. At 8 wk of age, 100 birds were surgically castrated and afterwards at 12 wk of age and at four-wk intervals, 10 intact cockerels and 10 capons were selected randomly and slaughtered. Cockerels, compared with capons, were characterized by a higher proportion of edible components at 24 and 28 wk of age, and a more desirable carcass tissue composition due to a higher content of lean meat in total body weight (BW). Capons had higher abdominal fat content than cockerels, which resulted in a higher percentage of non-edible components in their BW at 24 and 28 wk of age. Differences in the distribution of lean meat in the carcass were noted from 20 wk of age in both castrated and intact birds. The content of breast muscles increased in capons, and the content of leg muscles (thigh and drumstick) increased in cockerels. The results of this study indicate that in view of the optimal lean meat content of the carcass and the optimal distribution of major tissue components, Green-legged Partridge capons should be fattened for a maximum period of 24 wk.

  15. Family planning and the labor sector: soft-sell approach.

    Science.gov (United States)

    Teston, R C

    1981-01-01

    Dr. Cesar T. San Pedro, the director of the company clinic at Dole Philippines plantation in South Cotabato in Region 11, has been pressing the management to initiate a comprehensive family planning programs for their 10,000 workers. Pedro wants the Ministry of Labor and Employment (MOLE) to enforce its population program. The situation at Dole is one that requires an arbiter. Since 1977, there has not been a Population/Family Planning Officer (PFPO) for the area, and it is not possible to monitor closely if the qualified firms are following the labor code and providing family planning services to their employees. Susan B. Dedel, executive director of the PFPO, has reported that the office has sought to endear its program to the private sector by showing that family planning is also profitable for the firm. This "soft-sell" approach has been the hallmark of the MOLE-PFPO since it began in 1975 as a joint project of the Commission on Population (POPCOM), United Nations Fund for Population Activities (UNFPA), and International Labor Organization (ILO). Some critics have argued that this liberal style of implementation is short-selling the program. They point out that the Labor Code of 1973 enforces all establishments with at least 200 employees to have a free in-plant family planning program which includes clinic care, paid motivators, and volunteer population workers. The critics seem, at 1st glance, to have the statistics on their side. In its 5 years of operation, the PFPO has convinced only 137,000 workers to accept family planning. This is quite low, since of the 1.2 million employed by the covered firms, 800,000 are eligible for the MOLE program. Much of the weakness of the implementation is said to be due to the slow activation of the Labor-Management Coordinating Committees (LMCC). The critics maintain that because of the liberal enforcement of Department Order No. 9, the recalcitrant firms see no reason to comply. Dedel claims that the program is on the

  20. Urania in the Marketplace: Using Telescopes to Sell Consumer Goods

    Rumstay, Kenneth S.

    2018-01-01

    For well over a century the iconic image of the astronomical telescope has been widely used to promote distinctly non-astronomical consumer goods. One of the most famous of early examples is the 1893 Chicago newspaper advertisement for Kirk’s Soap, which was inspired by the opening of the Yerkes Observatory. But such usage was not limited to periodicals. Advertising trade cards had become popular at the end of the 17th century in Europe, notably in Paris and London. In a time prior to the introduction of formal systems of street address numbering, they served as both advertisement and map, directing consumers to the merchants' stores. In many cases, attention was drawn to the product by picturing it as a heavenly body to be observed telescopically! In the 20th century trade cards gave way to the modern business card, and manufacturers began to increasingly rely on magazine and newspaper (and radio and television) advertising. But the telescope remains an evocative image! In modern advertising we see it used to sell an incredible variety of consumer goods: candy, coffee, cigarettes, whiskey, foodstuffs, clothing; the list is endless! Examples of these, along with earlier Victorian-era usages, are presented. This work was supported by a faculty development grant from Valdosta State University.

  1. ON PRICE CHOICE AT SELLING OF INFORMATION RESOURCES

    2015-05-01

    Full Text Available The paper considers the problem of the pricing policy determination in the company, selling information resource at the market. The problem of the optimal price determination for an information resource is solved depending on the time for the case when the seller-company has no competitors in the market, the market is saturated, and buyers are not able to further spread of the resource. Conditions for the optimal choice of information resource price have been obtained; the maximum possible income of the company has been calculated for linear demand function, and conditions, determining the duration and volume of sales, providing the maximum of average income of the company, have been obtained as well. The problem of optimal price choice is solved by macrosystem approach that has made it possible to reduce it to the isoperimetric kind. It is shown that the optimal price dependence on time for a linear demand function should provide a linearly increasing rate of sales. Conditions have been derived under which the sales proceedings for an information resource are positive, relationship is determined between volume of sales and timeline at which the average income during the sales reaches its maximum. The results are given in dimensionless form, thereby reducing the number of independent parameters. These results are usable for the pricing analysis of software and other information products.

    Full Text Available In the present society, also identified as a "consumer society" (Bauman, 2008, people, irrespective of gender, age, social and financial conditions, are all called for consumption. In this article we turn to the childhood and approached one of the faces of their insertion into the society of consumers, trying to show how children are used to sell. As a frame of theoretical reference we adopt, among others, the writings of Zygmunt Bauman, Juliet Schor and Robert Bocock, dealing with contemporary versions of consumption. Analyzing weekly magazines of large circulation, we discuss how productive it is for the economic market the alliance between childhood and consumption and we argue that this use of children in publicity contributes for a new conception of childhood: the childhood of consumption. An erotized childhood, always wanting more and never feeling satisfied, focused in acquiring and showing off. This is the childhood that is coming to school with new interests, preferences and behavior, deserving our entire attention. Key-words: contemporary childhood, childhood and consumption, consumer society, advertising, magazines.

    Some countries have already tried and tested mechanisms of regulating distance sales as form of distribution of medicines that have been used more or less effectively for a fairly long time. Herewith, so far, the approach of the competent authorities of some countries including Ukraine can be called prevailing in quantitative terms under which the official prohibition on distance sales of medicines is set. The aim of this study is a detailed examination of the nature of the prohibition of the medicines distance selling in Ukraine, namely the an analysis of advantages and disadvantages of this form of distribution of medicines and identification of appropriate ways for gradual repeal of the prohibition in terms of regulatory reform in Ukraine in the sphere of circulation of medicines due to the process of adaptation of statutory regulation in this area to the EU legislation. This study is based on Ukrainian regulation acts, Council Directives 97/7/EC, 2000/31/EC, 2001/83/EC, scientific works and opinions of progressiveminded people in this sphere. Such methods as dialectical, comparative, analytic, synthetic and comprehensive have been used in the article. Reception of the described experience of regulation in EU will allow a further review of the principles of regulation in Ukraine in the sphere of medicines with a shift in the main emphasis in the direction of ensuring adequate consumer rights in this area and preventing the risks of patients' and public health.

  4. Selling orthodontic need: innocent business decision or guilty pleasure?

    Science.gov (United States)

    Ackerman, Marc Bernard

    2010-05-01

    The principal objective for most patients seeking orthodontic services is a detectable improvement in their dentofacial appearance. Orthodontic treatment, in the mind of the patient, is something that makes you look better, feel better about yourself, and perhaps enhances your social possibilities, ie, to find a companion or make a positive impression during a job interview. Orthodontics, as a speciality, has collectively advanced the idea that enhanced occlusion (bite) improves the health and longevity of the dentition, and as a result many patients seeking orthodontic services affirm that their secondary goal of treatment is an oral health benefit. It would appear that there is some disparity between the end-user of orthodontic services and the orthodontic provider's perception of what constitutes orthodontic need. The aim of this paper is to examine two contrasting models that characterise how dentists 'sell' orthodontic services to patients and to discuss the conflict between professional ethics, practice management and evidence-based decision-making in orthodontic practice.

    Full Text Available The purpose of the research is to investigate Romanian direct sellers’ perceptions on customers’ loyalty. The research objectives are: (1 to identify the direct sellers’ perceptions on the concept of loyalty; (2 to identify the main loyalty techniques that direct sellers use in their work with the clients; (3 to frame the portrait of a loyal customer. As a research method, we used qualitative research based on depth interviews. It is an exploratory and instrumental research, the results being used for building a questionnaire for a future survey. The investigated population is represented by direct selling women, with ages beteeen 19 and 30 years. For direct sellers, loyalty is an attitude and also a behavior, it means buying from the same company, from the same seller and preferring the products of the company. The main loyalty techniques that direct sellers use in their work with the clients are: promotional actions, personalization the relation with the client and offering stimulants. The loyal customer is the one who buys companies’ products every month or at least quarterly, spends a monthly amount of 100 Ron on these products, works with the same seller, pays on time for the order, doesn’t look only after promotions, loves the products, recommends the company to others, doesn’t return the order, wants to buy more products from the company and trusts its products.

  6. The selling of mental health services: some ethical reflections.

    1993-01-01

    Since the introduction of public mental health services in Israel, the main principle of our work has been to provide equal and free of charge health services to all patients. We were proud of our ability to provide optimal treatment to all patients in all our facilities, regardless of cost or status of insurance. During the last decade, the cost of providing good quality public health services, including mental health services, has constantly increased, and the system has reached a state of financial distress resulting in insufficiency and inability to perform properly. In order to maintain the level of mental health services, the health authorities started planning a system of payment for various mental health services which, until now, were supplied free of charge. This change of policy and attitude towards the population in need poses severe ethical and practical questions and problems. It is questionable that the amount of income ensuing from the sale of mental health services and whether a relatively small financial profit justify possible injury of the population in need of these services, especially the sicker and weaker members of it. This article raises some ethical doubts involved in charging money for psychiatric services that are given to this special group of the mentally ill, and claims that the feasibility of selling services in this area of public health should be reinvestigated.

    Dalmatia is an interesting place to study the use of wild greens as it lies at the intersection of influence of Slavs, who do not usually use many species of wild greens, and Mediterranean culinary culture, where the use of multiple wild greens is common. The aim of the study was to document the mixtures of wild green vegetables which are sold in all the vegetable markets of Dalmatia. All vendors (68) in all 11 major markets of the Dalmatian coast were interviewed. The piles of wild vegetables they sold were searched and herbarium specimens taken from them. The mean number of species in the mix was 5.7. The most commonly sold wild plants are: Sonchus oleraceus L., Allium ampeloprasum L., Foeniculum vulgare Mill., Urospermum picroides F.W.Schmidt, Papaver rhoeas L., Daucus carota L., Taraxacum sp., Picris echioides L., Silene latifolia Poir. and Crepis spp. Also the cultivated beet (Beta vulgaris L.) and a few cultivated Brassicaceae varieties are frequent components. Wild vegetables from the mix are usually boiled for 20-30 minutes and dressed with olive oil and salt. Altogether at least 37 wild taxa and 13 cultivated taxa were recorded.Apart from the mixes, Asparagus acutifolius L. and Tamus communis L. shoots are sold in separate bunches (they are usually eaten with eggs), as well as some Asteraceae species, the latter are eaten raw or briefly boiled. The rich tradition of eating many wild greens may result both from strong Venetian and Greek influences and the necessity of using all food resources available in the barren, infertile land in the past. Although the number of wild-collected green vegetables is impressive we hypothesize that it may have decreased over the years, and that further in-depth local ethnobotanical studies are needed in Dalmatia to record the disappearing knowledge of edible plants.

The most commonly sold wild plants are: Sonchus oleraceus L., Allium ampeloprasum L., Foeniculum vulgare Mill., Urospermum picroides F.W.Schmidt, Papaver rhoeas L., Daucus carota L., Taraxacum sp., Picris echioides L., Silene latifolia Poir. and Crepis spp. Also the cultivated beet (Beta vulgaris L. and a few cultivated Brassicaceae varieties are frequent components. Wild vegetables from the mix are usually boiled for 20–30 minutes and dressed with olive oil and salt. Altogether at least 37 wild taxa and 13 cultivated taxa were recorded. Apart from the mixes, Asparagus acutifolius L. and Tamus communis L. shoots are sold in separate bunches (they are usually eaten with eggs, as well as some Asteraceae species, the latter are eaten raw or briefly boiled. Conclusions The rich tradition of eating many wild greens may result both from strong Venetian and Greek influences and the necessity of using all food resources available in the barren, infertile land in the past. Although the number of wild-collected green vegetables is impressive we hypothesize that it may have decreased over the years, and that further in-depth local ethnobotanical studies are needed in Dalmatia to record the disappearing knowledge of edible plants.

    Avocados have a fairly short shelf life and are included in climacteric fruits. Edible coating application is one alternative to maintain the shelf life of avocado. Cassava peel starch is potential to be used as raw material for edible coating making. Addition of bay leaf extract containing antioxidants can increase the functional value of edible coating. The purpose of this study is to know the shrinkage of weight, acid number, color change and respiration rate of avocado coated with edible coating from cassava peel starch with an addition of bay leaf extract. The study consisted of making cassava peel starch, bay leaf extraction, edible coating making, edible coating application on avocado, and analysis of avocado characteristics during storage at room temperature. The results showed that addition of bay leaf extract on cassava peel starch edible coating applied to avocado, an effect on characteristics of avocado. Avocado applied edible coating and stored at room temperatures had lower weight loss than avocado without edible coating, lower acid number, tend to be more able to maintain color rather than avocado without edible coating.

  11. Recessions and the participation of youth in the selling and use of illicit drugs.

    Arkes, Jeremy

    2011-09-01

    There has been limited research on how recessions (or more generally, the strength of the economy) affect drug use and the related outcome of drug selling. This is especially important, given the current economic crisis. This paper aims to use a conceptual framework, previous research, and new research to predict how the current economic crisis may be affecting youth drug selling and drug use. A conceptual framework to understand how a recession could affect youth drug selling and drug use is presented, along with a review of the literature on empirical investigations on how the strength of the economy affects these behaviours among teenagers. In addition, new analyses for young adults are presented. The conceptual framework postulates that a recession would have direct positive effects on the prevalence of youth drug selling but ambiguous direct effects on youth drug use. The conceptual framework also postulates that drug selling and drug use are inter-connected at the individual level and the aggregate level. Thus, any effect of a recession on one would likely affect the other in the same direction. The limited empirical evidence indicates that both drug selling and drug use among youth are higher when the economy is weaker. The current economic crisis will likely increase both youth drug selling and drug use relative to what they would have otherwise been. Published by Elsevier B.V.

    Although studies have found that young adults who sell drugs are more likely to be involved in risky behaviors than those who do not sell drugs, there has been relatively little research that has explored heterogeneity among young adults who sell drugs. Using a pooled sample of 18 to 25 year olds from the National Survey on Drug Use and Health (2006-2010) who report past-year drug selling (N = 5,373), this study employs latent profile analysis to specify latent groups and assess the correlates of group membership. Findings indicate substantial differences among young adults who sell drugs. In particular, the analysis found four groups of drug sellers: normative (49.6%), club drug users (23.6%), polysubstance users (16.0%), and criminal offenders (10.8%). Club drug users were characterized by high levels of ecstasy and hallucinogen use, polysubstance users were more likely to be depressed and anxious, White and female than the other groups. Criminal offenders were overwhelmingly male and more likely to be comprised of African-Americans and Hispanics. RESULTS indicate that drug selling in early adulthood varies substantially. Contrary to media and popular notions most drug sellers are not involved in crime and polysubstance using drug sellers are in clear need of mental health services. Further, most drug sellers in this age range are White. Findings suggest that policy efforts that operate under the assumption of homogeneity of drug selling may be misguided.

    As most of the electric utilities in Germany have decided by now to adopt the multi-utility strategy for sales promotion in the open electricity market, a questionnaire has been distributed to 1 000 households in order to find out whether product bundling or cross selling in combination with the low-interest product 'electricity' is a good strategy to enlarge the customer basis. EFOplan (Munic University) and the consulting firm Accenture have been in charge of the survey. The results show the current status of insight of household customers and their motives to change supplier, as well as the pattern of demand for product bundling. (orig./CB) [German] Da mittlerweile die meisten EVUs eine Multi-Utility-Strategie anstreben, wurde mittels einer schriftlichen Befragung von 1 000 deutschen Haushalten untersucht, ob die Vermarktung von Zusatz- bzw.

    2011-03-01

    Edible films were manufactured from rapeseed oil extraction residues. To prepare rapeseed protein (RP) films, various concentrations of plasticizers and emulsifiers were incorporated into the preparation of a film-forming solution. The optimal conditions for the preparation of the RP film were 2% sorbitol/0.5% sucrose as plasticizer and 1.5% polysorbate 20 as an emulsifier. In addition, RP blend films were prepared. Gelidium corneum or gelatin was added to improve the physical properties of the RP film, and the highest tensile strength value of the films was 53.45 MPa for the 3% RP/4% gelatin film. Our results suggest that the RP-gelatin blend film is suitable for applications in food packaging. Edible RP films prepared in the present investigation can be applied in food packaging.

    2000-01-01

    The decontamination effects of gamma irradiation on the edible gelatin were studied. The results indicated that the bacterium and mold in the gelatin decreased significantly with the dose of 5 kGy treatment. However, the content of crude protein, microelement, amino acid in the gelatin remained unchanged under the irradiation of 4 and 8 kGy. The viscosity of the gelatin decreased with the increase of the irradiation dose, but the gelatin with a dose of 5 kGy treatment still accorded with the standard of the second-order class. These results suggested that the optimum irradiation dose for edible gelatin for the purpose of decontamination was in the range 3-5 kGy. (author)

    Cannabis and its principal active constituent, Δ9-tetrahydrocannabinol (THC), are increasingly available as edibles resembling commercially available food products. In this case series, we describe a population of predominantly pediatric patients who were inadvertently exposed to a THC-containing product in San Francisco. Twelve children and 9 adults were identified, with 16 patients having detectable serum THC and THC metabolites. All patients presented to hospitals with a variety of constitutional symptoms and all were discharged home within 12 hours. In general, pediatric patients had more severe symptoms and longer hospital length of stay, and, uniquely, a majority presented with leukocytosis and elevated lactic acid levels. We recommend that efforts be made to increase general public awareness in regard to the potential hazards of THC-containing edibles resembling commercially available food products.

    Full Text Available EFFECT OF PLASTICIzER ON THE PECTINIC EDIBLE FILM CHARACTERISTICS. The peel of Balinese Citrus contains high concentration of pectin which can be further processed to be edible films. The edible films can be utilized as a food coating which protects the food from any external mass transports such as humid, oxygen, and soluble material and can be served as a carrier to improve the mechanical-handing properties of the food. Edible films made of organic polymers tend to be brittle and thus addition of a plasticizer is required during the process. The work studies the effect of the type and the concentration of plasticizers on the tensile strength, the elongation of break, and the water vapor permeabilty of the edible film. Sorbitol and glycerol were used as plasticizers. Albedo from the citrus was hydrolized with hydrochloride acid 0.1 N to get pectinate substance. Pectin was then dissolved in water dan mixed with the plasticizers and CaCl2.2H2O solution. The concentrations of the plasticizers were 0, 0.03, 0.05, 0.1, and 0.15 mL/mL of solution. The results showed that increasing the concentration of plasticizers will decrease the tensile strength, but increase the elongation and film permeability. Sorbitol-plasticized films are more brittle, however exhibited higher tensile strength and water vapor permeability than of glycerol-plasticized film. The results suggested that glycerol is better plasticizer than sorbitol.  Kulit jeruk bali banyak mengandung pektin yang dapat dimanfaatkan sebagai bahan baku edible film. Edible film bisa digunakan untuk melapisi bahan makanan, melindungi makanan dari transfer massa eksternal seperti kelembaban, oksigen, dan zat terlarut, serta dapat digunakan sebagai carrier untuk meningkatkan penanganan mekanik produk makanan. Film yang terbuat dari bahan polimer organik ini cenderung rapuh sehingga diperlukan penambahan plasticizer. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh kadar dan jenis

    Time resolved thermal lens (TL) spectrometry is applied to the study of the thermal diffusivity of edible oils such as olive, and refined and thermally treated avocado oils. A two laser mismatched-mode experimental configuration was used, with a He Ne laser as a probe beam and an Ar+ laser as the excitation one. The characteristic time constant of the transient thermal lens was obtained by fitting the experimental data to the theoretical expression for a transient thermal lens. The results showed that virgin olive oil has a higher thermal diffusivity than for refined and thermally treated avocado oils. This measured thermal property may contribute to a better understanding of the quality of edible oils, which is very important in the food industry. The thermal diffusivity results for virgin olive oil, obtained from this technique, agree with those reported in the literature.

    The effect of formulated Aloe vera based edible coating on mass loss, colour, firmness, pH, acidity, total soluble solid, ascorbic acid and lycopene on the coated tomato was investigated. The tomato in control showed a rapid deterioration with an estimated shelf life period of 19 days, based on the mass loss, colour changes, accelerated softening and ripening. On the contrary, the coating on tomatoes delayed the ripening and extended the shelf life up to 39 days. The physiological loss in weight was 7.6 and 15.1%, firmness was 36 and 46.2 N on 20th day for control and coated tomatoes, respectively. From the results, it was concluded that the use of Aloe vera based edible coating leads to increased tomato shelf-life.

    The NE region of India falls in the global hotspot of biodiversity. Wild edible plants (WEPs) are widely consumed in the daily diet of the local people. WEPs are critical for the sustenance of ethnic communities and also as a source of income. However, WEPs received a little attention in research activities, economic development, biodiversity conservation and sustainable management. Many are largely ignored and remained unexplored. With a view of reducing the gap in traditional knowledge and tapping the hidden potential resources for proper utilization, exploitation, and sustainable management of WEPs are crucial. Surveys were conducted at 20 major markets in all districts of Manipur throughout different seasons from August 2012 to March 2014. A total of 154 avid plant collectors and sellers were interviewed using semi-structured questionnaire, formal, informal and extensive interactions to gather detailed information about these species. An integrated assessment of 68 wild leafy vegetables was also carried out to prioritize them for proper exploitation, conservation, and sustainable management. A total of 68 wild edible vegetables belonging to 42 families were documented which are being used by indigenous communities for nutritive and therapeutic purposes. Of these species, 54 are perennial (79 %) while others are annual (19 %). Herbaceous plants make up the highest proportion of edible plants. Leaves are dominant edible part followed by shoot and stem, and most are consumed through cooked food. Further, 57 species (84 %) are commonly available, and 11 (16 %) are rare. According to integrated assessment, 2 species have highest integrated value, 26 species have high value, 31 species have general value and 9 species are of low value. The majority of the species have a high or general value. Manipur has rich wild vegetable resources. However, many of them are seldom collected or cultivated given their importance in sustaining and diversifying diet. A

    Edible flowers are increasingly being used in culinary preparations, being also recognized for their potential valuable effects in human health, which require new approaches to improve their conservation and safety. These highly perishable products should be grown without using any pesticide. Irradiation treatment might be the answer to these problems, ensuring food quality, increasing shelf-life and disinfestation of foods. Irradiation treatment might be the answer to these problems, to ensure food quality, to increase shelf-life and disinfestation of foods. Tropaeolum majus L. (nasturtium) and Viola tricolor L. (johnny-jump-up) flowers are widely used in culinary preparations, being also acknowledged for their antioxidant properties and high content of phenolics. The purpose of this study was to evaluate the dose-dependent effects of gamma and electron beam irradiation (doses of 0, 0.5, 0.8 and 1 kGy) on the antioxidant activity, phenolic compounds, physical aspects and antiproliferative potential of edible flowers. Kaempferol-O-hexoside-O-hexoside was the most abundant compound in all samples of Tropaeolum majus flower while pelargonidin-3-O-sophoroside was the major anthocyanin. In general, irradiated samples gave higher antioxidant activity, probably due to their higher amounts of phenolic compounds, which were also favored by the 1.0 kGy dose, regardless of the source . The Viola tricolor samples displayed flavonols as the most abundant phenolic compounds, particularly those derived from quercetin. In general, gamma-irradiated samples, independently of the applied dose, showed higher amounts in phenolic compounds, which were also favored by the 1.0 kGy dose, regardless of the source. The antioxidant activity was also higher among irradiated samples. The two species of edible flowers have not provided the samples did not show potential antiproliferative and cytotoxicity. Accordingly, the applied irradiation treatments seemed to represent a feasible technology

    2018-05-01

    Full Text Available Type-1 diabetes (T1D is a metabolic disease involving the autoimmune destruction of insulin-producing pancreatic beta cells. It is often diagnosed by the detection of autoantibodies, typically those recognizing insulin itself or the 65-kDa isoform of glutamic acid decarboxylase (GAD65. Oral insulin can be used to induce systemic immunological tolerance and thus prevent or delay the onset of T1D, suggesting that combination treatments with other autoantigens such as GAD65 could be even more successful. GAD65 has induced oral tolerance and prevented T1D in preclinical studies but it is difficult to produce in sufficient quantities for clinical testing. Here we combined edible plant systems, namely spinach (Spinacia oleracea cv Industra and red beet (Beta vulgaris cv Moulin Rouge, with the magnICON® expression system to develop a safe, cost-effective and environmentally sustainable platform for the large-scale production of GAD65. The superior red beet platform was extensively characterized in terms of recombinant protein yields and bioequivalence to wild-type plants, and the product was tested for its ability to resist simulated gastric digestion. Our results indicate that red beet plants are suitable for the production of a candidate oral vaccine based on GAD65 for the future preclinical and clinical testing of T1D immunotherapy approaches.

    Full Text Available Once local expert knowledge regarding the harvesting of various non-timber forest products (NTFPs is lost, it is difficult to recover. We investigated whether the knowledge of expert forest harvesters can be used to determine the habitat distribution and harvesting sites of three popular edible wild ferns, i.e., ostrich fern (Matteuccia struthiopteris, bracken (Pteridium aquilinum, and royal fern (Osmunda japonica, in mountainous communities of western Fukushima, Japan. Using multi-criteria evaluation (MCE based on the analytic hierarchy process (AHP and geographic information system (GIS, we found that harvesters were easily able to recognize differences in the spatial characteristics of the habitat distribution of fern species due to both natural and anthropogenic factors. These factors were described by various GIS layers, such as vegetation and terrain features (e.g., gradient, aspect, and slope position derived from a 20-m digital elevation model (DEM. Harvesting sites were limited by their distance from a roadway, which differed among species. By comparison with the GPS records of actual harvesting sites, we estimated the potential harvesting sites of each fern species with reasonable accuracy, particularly for bracken. Our results show that the knowledge of expert forest harvesters can be quantified using MCE and GIS, which is useful for determining the spatial characteristics of NTFP harvesting and ensuring sustainable management practices.

  18. Potential alternatives to edible oils for biodiesel production - A review of current work

    International Nuclear Information System (INIS)

    Balat, Mustafa

    2011-01-01

    Biodiesel production is a very modern and technological area for researchers due to the relevance that it is winning everyday because of the increase in the petroleum price and the environmental advantages. Currently, biodiesel is mainly prepared from conventionally grown edible oils such as rapeseed, soybean, sunflower and palm thus leading to alleviate food versus fuel issue. About 7% of global vegetable oil supplies were used for biodiesel production in 2007. Extensive use of edible oils may cause other significant problems such as starvation in developing countries. The use of non-edible plant oils when compared with edible oils is very significant in developing countries because of the tremendous demand for edible oils as food, and they are far too expensive to be used as fuel at present. The production of biodiesel from different non-edible oilseed crops has been extensively investigated over the last few years. (author)

  19. Physiological limits to zinc biofortification of edible crops

    Full Text Available It has been estimated that almost one third of the world’s population lack sufficient Zn for adequate nutrition. This can be alleviated by increasing dietary Zn intakes through Zn-biofortification of edible crops. Biofortification strategies include the application of Zn-fertilisers or the development of crop genotypes that acquire more Zn from the soil and accumulate it in edible portions. Zinc concentrations in roots, leaves and stems can be increased through the application of Zn-fertilisers. Root Zn concentrations of up to 500-5000 mg kg-1 DM, and leaf Zn concentrations of up to 100-700 mg kg-1 dry matter (DM, can be achieved without loss of yield when Zn-fertilisers are applied to the soil. It is possible that greater Zn concentrations in non-woody shoot tissues can be attained using foliar Zn-fertilisers. By contrast, Zn concentrations in fruits, seeds and tubers are severely limited by low Zn mobility in the phloem and Zn concentrations higher than 30-100 mg kg-1 DM are rarely observed. However, genetically modified plants with improved abilities translocate Zn in the phloem might be used to biofortify these phloem-fed tissues. In addition, genetically modified plants with increased tolerance to high tissue Zn concentrations could be used to increase Zn concentrations in all edible produce and, thereby, increase dietary Zn intakes.

    Green chillies were coated with a composite edible coating composed of gum arabic (5%), glycerol (1%), thyme oil (0.5%) and tween 80 (0.05%) to preserve the freshness and quality of green chillies and thus reduce the cost of preservation. In the present work, the chillies were coated with the composite edible coating using the dipping method with three dipping times (1, 3 and 5 min). The physicochemical parameters of the coated and control chillies stored at room temperature (28±2ºC) were evaluated at regular intervals of storage. There was a significant difference (p≤0.05) in the physicochemical properties between the control chillies and coated chillies with 1, 3 and 5 min dipping times. The coated green chillies showed significantly (p≤0.05) lower weight loss, phenolic acid production, capsaicin production and significantly (p≤0.05) higher retention of ascorbic acid, total chlorophyll content, colour, firmness and better organoleptic properties. The composite edible coating of gum arabic and thyme oil with 3 min dipping was effective in preserving the desirable physico-chemical and organoleptic properties of the green chillies up to 12 days, compared to the uncoated chillies that had a shelf life of 6 days at room temperature.

    Edible films/coatings have been considered as one of the potential technologies that can be used to increase the storability of foods and to improve the existent packaging technology, helping to ensure the microbial safety and the preservation of food from the influence of external factors. Innovations constantly appear in food packaging, always aiming at creating a more efficient quality preservation system while improving foods' attractiveness and marketability. The utilization of renewable sources for packaging materials, such as hydrocolloids and lipids from biological origin, is one the main trends of the industry. These films should have acceptable sensory characteristics, appropriate barrier properties (CO2, O2, water, oil), microbial, biochemical and physicochemical stability, they should be safe, and produced by simple technology in low cost. Also they can act as effective carrier for antioxidant, flavor, color and nutritional or anti-microbial additives. Nowadays, a great discussion exists about the potential applications of edible films/coatings on food products. The general trend is to find the correct combination between the food product and the edible film/coating, which will ensure the success of the technology.

    Edible flowers have gained more attention in recent years thanks to their perceived health benefits. Despite this attention, it seems that edible flowers are not popularized for consumption in South America, being considered unfamiliar for some cultures from this continent. In this context, the general goal of the present study was to investigate the three dimensions of social representation theory, the representational field, the information and the attitude of the two conditions of edible flowers: a more general "food made with flowers" and more directional product "yoghurt made with flowers", using Brazilian consumers. To achieve this goal, a free word association task was applied. A total of 549 consumers participated in this study. Participants were divided into two conditions, in which the inductor expressions for the free word association task changed: (a) food products made with flowers and (b) yoghurt made with flowers. Results showed a very positive attitude to both situations, and consumers associated Food products made with flowers to "health care" while the central core of yoghurt made with flowers reflected the innovative condition of this product, supported here by their unpredictable character (information generated).

    Full Text Available This study investigated properties of starch-based edible films with oregano and black cumin essential oil addition. Essential oils addition positively affected film swelling (decreased due to essential oil addition, mechanical properties (tensile strength decreased while elongation at break increased, and water vapor barrier properties (decreased along with essential oils addition. Control film did not have any biological activity, which proves the need for essential oils addition in order to obtain active packaging. Oregano oil was more effective in terms of biological activity. Endothermal peak, above 200°C, represents total thermal degradation of edible films. Diffraction pattern of control film showed significant destruction of A-type crystal structure. Addition of essential oils resulted in peak shape change: diffraction peaks became narrower. Principal Component Analysis has been used to assess the effect of essential oils addition on final starch-based edible films characteristics with the aim to reveal directions for the film characteristics improvement, since the next phase will be optimal film application for food packaging.

    2013-05-01

    Insects, a traditional food in many parts of the world, are highly nutritious and especially rich in proteins and thus represent a potential food and protein source. A compilation of 236 nutrient compositions in addition to amino acid spectra and fatty acid compositions as well as mineral and vitamin contents of various edible insects as derived from literature is given and the risks and benefits of entomophagy are discussed. Although the data were subject to a large variation, it could be concluded that many edible insects provide satisfactorily with energy and protein, meet amino acid requirements for humans, are high in MUFA and/or PUFA, and rich in several micronutrients such as copper, iron, magnesium, manganese, phosphorous, selenium, and zinc as well as riboflavin, pantothenic acid, biotin, and in some cases folic acid. Liabilities of entomophagy include the possible content of allergenic and toxic substances as well as antinutrients and the presence of pathogens. More data are required for a thorough assessment of the nutritional potential of edible insects and proper processing and decontamination methods have to be developed to ensure food safety. © 2013 WILEY-VCH Verlag GmbH & Co.

    Edible bird nest (EBN) produced by certain swiftlet species mainly, Aerodromus fuciphagus. The objectives of this study were to determine and compare the proximate and amino acid composition of EBN obtained from two regions in Peninsular Malaysia (Pahang-A & Terengganu-B). The solubility of edible bird nest with varying pH, temperature and time was also investigated in this study. The results showed that, the EBN contained crude protein accounted to 58.55% (A) and 55.48% (B), carbohydrate at22.28% (A) & 25.79% (B), moisture content 15.90% (A) & 15.87% (B), fat, 0.67% (A) & and 0.29% (B) and ash contents 2.60% (A) & 2.57% (B) respectively. The major amino acids found in edible bird nest EBN were Glutamic acid (9.61%), Aspartic acid (6.34%), Lysine (5.44 %) and also Leucine (5.30%). The total solubility of EBN was also found to be increased when the temperature was increased increase with distilled water yielding the highest total solubility of EBN compared to others buffer (different pH) solutions.

    The aim of this work was to investigate the effect of various microwave heating times (1, 3, 5, 10, and 15min) on the chemical properties of novel edible oil sources, including Mashhadi melon (Cucumis melo var. Iranians cv. Mashhadi), Iranian watermelon (Citrullus lanatus cv. Fire Fon), pumpkin (Cucurbita pepo subsp. pepo var. Styriaca), and yellow apple (Malus domestica cv. Golden Delicious) seed oils. The evaluated parameters were peroxide value (PV), conjugated diene (CD) and triene (CT) values, carbonyl value (CV), p-anisidine value (AnV), oil stability index (OSI), radical scavenging activity (RSA), total tocopherols, total phenolics, as well as chlorophyll and carotenoid contents. Results showed that extended microwave heating involves decreased quality of the seed oils, mainly due to the formation of primary and secondary oxidation products. Microwave heating time also affects the total contents of chlorophylls, carotenoids, phenolics and tocopherols, which clearly decrease by increasing the exposure time. The order of oxidative stability of the analyzed edible oils was pumpkin>Mashhadi melon>Iranian watermelon>yellow apple. The obtained results demonstrated the promising potential of these novel edible oils for different food applications. Copyright © 2016 Elsevier Ltd. All rights reserved.

    A spent bleaching earth (SBE) from an edible oil refinery has been regenerated by thermal processing in oven, followed by washing with a cold solution of hydrochloric acid (1M). Optimal regeneration conditions have been controlled by decolorization tests of degummed and neutralized soybean oil. Optimal values of treatment (temperature 350°C, carbonization time 01 h, and HCl concentration 1M) gave a very efficient material. After bleaching oil by regenerated spent bleaching earth (RSBE), the chlorophyll-a and β-carotenes contained in crude edible oil and observed respectively at 430, 454, and 483 nm, value of λ max , are very much decreased. The results obtained after decolorization of edible oil by RSBE material indicate, that, during the process, the bleaching oil did not undergo any changes in the free fatty acid content. The peroxide value (PV) was reduced from 4.2 to 1.8 meq O 2 /kg, and the color has been improved (Lovibond color yellow/red: from 50/0.5 to 2.7/0.3, respectively). The RSBE material obtained was characterized by several techniques (FTIR, SEM). The results show that the heat treatment did not affect the mineral structure of RSBE, and the regenerated material recovered its porous structure.

    2018-02-01

    Seafood is highly perishable and has a short shelf-life. During storage many reactions occur leading to changes in quality such as endogenous chemical and enzymatic reactions. The safety and shelf-life are related to the presence of food spoilage and pathogenic microorganisms. Despite improved manufacturing facilities and implementation of effective process control procedures such as the Hazard Analysis Critical Control Point system by seafood companies, the number of seafood-related foodborne illnesses has increased. Edible coatings can improve the quality of fresh and frozen products by retarding microbial growth, reducing lipid oxidation and moisture loss, and functioning as a carrier of food additives such as antimicrobial and antioxidant agents. Biodegradable edible coatings have various advantages over synthetic coatings such as being edible and generally being more environmentally friendly. This paper reviews the application of various types of natural bio-polymer and different active ingredients incorporated into the films and their effects on seafood quality attributes.

    Sales of edible marijuana products have been strong in Colorado and Washington State since the legalization of recreational marijuana. Initially, these states did not have comprehensive labelling or packaging requirements in place. In response to increases in marijuana-related emergency room visits and poison control centre calls, additional regulations were implemented. Currently, Alaska, Colorado, Oregon, and Washington each have passed into law various labelling and packaging requirements for edibles. This article presents the primary legal research findings of relevant statutes and regulations for edibles in Alaska, Colorado, Oregon, and Washington. These laws were identified by using Boolean terms and connectors searches in these states' legal databases in LexisNexis. Alaska, Colorado, Oregon, and Washington vary greatly in how they regulate labelling and packaging. Colorado, Oregon and Washington require a Universal Symbol to be affixed to edibles, but only Oregon and Washington require that the use of pesticides be disclosed on the label. Only Colorado and Oregon require that the packaging for edibles bear a Nutrition Facts Panel on the label. Δ 9 -Tetrahydracannabinol (THC) in a single serving or single edible product as Alaska and Oregon. All four states prohibit the manufacture or packaging of edibles that appeal to youth. State laws governing recreational marijuana edibles have evolved since the first recreational edible products were available for sale. Alaska, Colorado, Oregon, and Washington now require edible product labels to disclose a variety of product information, including risk factors associated with consumption. However, there still remain concerns about the regulatory gaps that exist in each of these states, inherent difficulties in enforcing laws around the labelling, packaging, and manufacturing of edibles, and the outstanding question of whether these edible laws are actually informing consumers and keeping the public safe.

    Full Text Available The aim of this study was to determine the effects of castration and age on the content of edible and non-edible components, and the distribution of tissue components in the carcasses of cockerels and capons. The study was conducted on 200 birds (Green-legged Partridge, divided into two sex categories (with 5 replications per group and 20 birds per replication, raised to 28 wk of age. At 8 wk of age, 100 birds were surgically castrated and afterwards at 12 wk of age and at four-wk intervals, 10 intact cockerels and 10 capons were selected randomly and slaughtered. Cockerels, compared with capons, were characterized by a higher proportion of edible components at 24 and 28 wk of age, and a more desirable carcass tissue composition due to a higher content of lean meat in total body weight (BW. Capons had higher abdominal fat content than cockerels, which resulted in a higher percentage of non-edible components in their BW at 24 and 28 wk of age. Differences in the distribution of lean meat in the carcass were noted from 20 wk of age in both castrated and intact birds. The content of breast muscles increased in capons, and the content of leg muscles (thigh and drumstick increased in cockerels. The results of this study indicate that in view of the optimal lean meat content of the carcass and the optimal distribution of major tissue components, Green-legged Partridge capons should be fattened for a maximum period of 24 wk.

    2017-07-01

    Buprenorphine medication-assisted treatment (B-MAT) is an efficacious and popular outpatient treatment for opioid use disorder. However, the likelihood of buprenorphine diversion is a public health concern. We examined the relationship between attitudes toward diversion as predictors of both sharing and selling buprenorphine. Participants (n=476) were patients undergoing short-term inpatient opioid detoxification. Multinomial logistic regression was used to estimate the adjusted association of sharing and selling buprenorphine with demographics, substance use behaviors, and attitudes toward sharing and selling buprenorphine. Among the two hundred persons who had ever been prescribed buprenorphine (73.4% male, 89% heroin users), 50.5% reported they had shared buprenorphine and 28.0% reported they had sold buprenorphine. Controlling for other covariates, the odds of sharing buprenorphine were 3.17 (95% CI 1.21; 8.32) times higher for persons who agreed that it was "right to share buprenorphine with dope sick friends" than for those who did not agree with this attitude. Attitudes toward selling (OR 2.92; 95% CI 1.35; 6.21) and sharing (OR 4.12; 95% CI 1.64; 10.32) buprenorphine were the only significant correlates of selling, with the odds of selling exponentially greater among persons with favorable attitudes toward sharing or selling buprenorphine. Although considered diversion, sharing B-MAT is normative among B-MAT patients. Assessing B-MAT patients' attitudes about diversion may help identify patients requiring enhanced oversight, education, or intervention aimed at modifying attitudes to reduce their likelihood to share or sell buprenorphine.

    Salman Popattia, Amber; Winch, Sarah; La Caze, Adam

    2018-04-01

    The widespread sale of complementary medicines in community pharmacy raises important questions regarding the responsibilities of pharmacists when selling complementary medicines. This study reviews the academic literature that explores a pharmacist's responsibilities when selling complementary medicines. International Pharmaceutical Abstracts, Embase, PubMed, Cinahl, PsycINFO and Philosopher's index databases were searched for articles written in English and published between 1995 and 2017. Empirical studies discussing pharmacists' practices or perceptions, consumers' expectations and normative studies discussing ethical perspectives or proposing ethical frameworks related to pharmacists' responsibilities in selling complementary medicines were included in the review. Fifty-eight studies met the inclusion criteria. The majority of the studies discussing the responsibilities of pharmacists selling complementary medicines had an empirical focus. Pharmacists and consumers identified counselling and ensuring safe use of complementary medicines as the primary responsibilities of pharmacists. No formal ethical framework is explicitly employed to describe the responsibilities of pharmacists selling complementary medicines. To the degree any ethical framework is employed, a number of papers implicitly rely on principlism. The studies discussing the ethical perspectives of selling complementary medicines mainly describe the ethical conflict between a pharmacist's business and health professional role. No attempt is made to provide guidance on appropriate ways to resolve the conflict. There is a lack of explicit normative advice in the existing literature regarding the responsibilities of pharmacists selling complementary medicines. This review identifies the need to develop a detailed practice-specific ethical framework to guide pharmacists regarding their responsibilities when selling complementary medicines. © 2018 Royal Pharmaceutical Society.

    Full Text Available Before internet was invented, there were invented numerous networks that helped American businesses in multiple savings. First of, they didn’t spend money on buying printers or scanners for the computers they possessed, meaning that the money spent before on buying hundreds of them, now was saved and used to buy a few of printers and scanners. How was this done? This worked by binding the entire computers of a floor to a single network. Second, the factor mostly taken into account is the energy saving and various abuses. Imagine the enormous amount of electricity that hundreds of printers and scanners would spend  and how much energy tens of them would spend, moreover  just think about how much these devices would be used in offices, where nobody is looking, for personal interests. American business, as the most creative one and the strongest was bothered by only one thing . This was the misuse of secret corporation information. These abuses occurred when the data had to be printed and transferred to corporate subsidiaries around the world. During the transfer the data could also be lost or damaged (intentionally or unintentionally and then the corporation would suffer losses (the data were transferred via floppy discs, or they were printed in hard copies. The solution for these problems came from the US military that had invented the internet earlier and after having consumed it for its own needs, decided to put it up for American businesses. The internet has developed its own services such as : www, ftp, e-mail, and buying and selling though internet (e-commerce. Nowadays, information exchanges with corporate branches are not made roughly, but electronically in real time. Additionally, this made it possible for a new category of web designers to be created and they created a powerful web-site through which some businesses created virtual shops and they started earning more money than they used to, in their physical stores.

    Wild lettuce (Lactuca virosa) can cause toxic effects when eaten. Wild lettuce grows in the north of Iran and some natives consume it unaware of its adverse side effects. We describe eight patients with manifestations of wild lettuce toxicity, admitted to a general hospital affiliated to the Golestan University of Medical Sciences. All the patients recovered (although one had to spend 48 h in the intensive care unit) and no chronic complications were reported. A clinical suspicion of toxicity...

  5. How does a carnivore guild utilise a substantial but unpredictable anthropogenic food source? Scavenging on hunter-shot ungulate carcasses by wild dogs/dingoes, red foxes and feral cats in south-eastern Australia revealed by camera traps.

    Full Text Available There is much interest in understanding how anthropogenic food resources subsidise carnivore populations. Carcasses of hunter-shot ungulates are a potentially substantial food source for mammalian carnivores. The sambar deer (Rusa unicolor is a large (≥ 150 kg exotic ungulate that can be hunted throughout the year in south-eastern Australia, and hunters are not required to remove or bury carcasses. We investigated how wild dogs/dingoes and their hybrids (Canis lupus familiaris/dingo, red foxes (Vulpes vulpes and feral cats (Felis catus utilised sambar deer carcasses during the peak hunting seasons (i.e. winter and spring. We placed carcasses at 1-km intervals along each of six transects that extended 4-km into forest from farm boundaries. Visits to carcasses were monitored using camera traps, and the rate of change in edible biomass estimated at ∼ 14-day intervals. Wild dogs and foxes fed on 70% and 60% of 30 carcasses, respectively, but feral cats seldom (10% fed on carcasses. Spatial and temporal patterns of visits to carcasses were consistent with the hypothesis that foxes avoid wild dogs. Wild dog activity peaked at carcasses 2 and 3 km from farms, a likely legacy of wild dog control, whereas fox activity peaked at carcasses 0 and 4 km from farms. Wild dog activity peaked at dawn and dusk, whereas nearly all fox activity occurred after dusk and before dawn. Neither wild dogs nor foxes remained at carcasses for long periods and the amount of feeding activity by either species was a less important predictor of the loss of edible biomass than season. Reasons for the low impacts of wild dogs and foxes on sambar deer carcass biomass include the spatially and temporally unpredictable distribution of carcasses in the landscape, the rapid rate of edible biomass decomposition in warm periods, low wild dog densities and the availability of alternative food resources.

    In this study, four common heavy metals, lead (Pb), cadmium (Cd), arsenic (As) and mercury (Hg) in rice and edible mushrooms of China were studied to evaluate contamination level and edible safety. Ninety two (92) rice samples were collected from the main rice growing regions in China, and 38 fresh and 21 dry edible mushroom samples were collected from typical markets in Nanjing City. The analyzed metal concentrations were significantly different between rice and edible mushroom samples (price samples respectively, were above maximum allowable concentration (MAC). In fresh edible mushroom, Pb and Hg contents in 2.6% samples were above MAC, respectively. However, only Hg content in 4.8% dry edible mushroom samples was above its MAC. Therefore, more than 95% rice and edible mushroom samples in our test had high edible safety. Copyright © 2013 Elsevier Ltd. All rights reserved.

  11. A stated preference investigation into the Chinese demand for farmed vs. wild bear bile.

    Directory of Open Access Journals (Sweden)

    Adam J Dutton

    Full Text Available Farming of animals and plants has recently been considered not merely as a more efficient and plentiful supply of their products but also as a means of protecting wild populations from that trade. Amongst these nascent farming products might be listed bear bile. Bear bile has been exploited by traditional Chinese medicinalists for millennia. Since the 1980s consumers have had the options of: illegal wild gall bladders, bile extracted from caged live bears or the acid synthesised chemically. Despite these alternatives bears continue to be harvested from the wild. In this paper we use stated preference techniques using a random sample of the Chinese population to estimate demand functions for wild bear bile with and without competition from farmed bear bile. We find a willingness to pay considerably more for wild bear bile than farmed. Wild bear bile has low own price elasticity and cross price elasticity with farmed bear bile. The ability of farmed bear bile to reduce demand for wild bear bile is at best limited and, at prevailing prices, may be close to zero or have the opposite effect. The demand functions estimated suggest that the own price elasticity of wild bear bile is lower when competing with farmed bear bile than when it is the only option available. This means that the incumbent product may actually sell more items at a higher price when competing than when alone in the market. This finding may be of broader interest to behavioural economists as we argue that one explanation may be that as product choice increases price has less impact on decision making. For the wildlife farming debate this indicates that at some prices the introduction of farmed competition might increase the demand for the wild product.

    Full Text Available Abstract Background Tanzania is a wild orchid biodiversity hotspot and has a high prevalence of HIV/AIDS. The wild orchids in the study are endemic and protected by the Convention on International Trade in Endangered Species. Every year, however, between 2.2 and 4.1 million orchid plants consumed in Zambia are estimated as originating from Tanzania. This research examines the differences between HIV/AIDS wild edible orchid gatherers and non-HIV/AIDS gatherers with regards to the frequency of gathering, salience in naming the various orchids, gathering knowledge acquisition and perceptions regarding the current state of abundance of the edible species. Methods Data was collected through interviews with 224 individuals in the Makete District of Tanzania close to the boarder of Zambia. Free-listings were conducted and Sutrup's Cultural Significance Index (CSI constructed. The independent t-test was used to compare the differences in gathering frequencies between affected and non-affected gatherers. A multiple comparison of the 4 subgroups (affected adults and children, and non-affected adults and children in gathering frequencies was done with a one way ANOVA test and its post hoc test. To examine the difference between affected and non-affected gatherers difference in source of gathering knowledge, a chi square test was run. Results Forty two vernacular names of gathered orchid species were mentioned corresponding to 7 botanical species belongs to genera Disa, Satyrium, Habenaria, Eulophia and Roeperocharis. Ninety-seven percent of HIV/AIDS affected households state that orchid gathering is their primary economic activity compared to non-HIV/AIDS affected households at 9.7 percent. The HIV/AIDS affected gathered significantly more often than the non-affected. AIDS orphans, however, gathered most frequently. Gatherers perceive a decreasing trend of abundance of 6 of the 7 species. Gathering activities were mainly performed in age based peer groups

    2018-01-01

    An increased societal focus on wildlife as food and recent policy deliberations regarding legal markets for wild-harvested meat are encouraging wildlife managers and researchers to examine the amount, use, and distribution of meat yielded through recreational hunting. We used responses to questions on the Michigan Deer Harvest Study to estimate the maximum yield of edible venison and assess hunters’ sharing behaviors. We estimated 11,402–14,473 metric tons of edible venison were procured during the 2013 hunting season. Of hunters who harvested a deer, 85% shared their venison. Hunters who shared did so with an average of 5.6 people (SD = 4.5). Sharing occurred most frequently within tight social networks: members of hunters’ households (69%), relatives (52%), and friends, neighbors, or coworkers (50%). In the absence of legal markets, venison is distributed widely by hunters and greatly amplifies the number of people benefiting from hunting. Nonetheless, we also identified the potential breadth of exposure to disease or contaminants from wild-harvested meat.

  16. Advances in edible coatings for fresh fruits and vegetables: a review.

    Dhall, R K

    2013-01-01

    Edible coatings are an environmentally friendly technology that is applied on many products to control moisture transfer, gas exchange or oxidation processes. Edible coatings can provide an additional protective coating to produce and can also give the same effect as modified atmosphere storage in modifying internal gas composition. One major advantage of using edible films and coatings is that several active ingredients can be incorporated into the polymer matrix and consumed with the food, thus enhancing safety or even nutritional and sensory attributes. But, in some cases, edible coatings were not successful. The success of edible coatings for fresh products totally depends on the control of internal gas composition. Quality criteria for fruits and vegetables coated with edible films must be determined carefully and the quality parameters must be monitored throughout the storage period. Color change, firmness loss, ethanol fermentation, decay ratio and weight loss of edible film coated fruits need to be monitored. This review discusses the use of different edible coatings (polysaccharides, proteins, lipids and composite) as carriers of functional ingredients on fresh fruits and vegetables to maximize their quality and shelf life. This also includes the recent advances in the incorporation of antimicrobials, texture enhancers and nutraceuticals to improve quality and functionality of fresh-cut fruits. Sensory implications, regulatory status and future trends are also reviewed.

    2017-10-01

    To examine discrete purchasing behaviors of marijuana-infused edibles from medical marijuana dispensaries with the aim to identify potential venue- and individual-level targets for prevention. Two-stage, venue-based sampling approach was used to randomly select patrons exiting 16 medical marijuana dispensaries in Los Angeles, California during Spring 2013. Hierarchical generalized linear modeling was used to examine the likelihood of purchasing edibles among 524 patrons reporting a discrete purchase regressed on characteristics of the sampled dispensaries and their patrons. At a venue level, patrons were more likely to purchase edibles from dispensaries located within Census tracts with higher median incomes or in close proximity to a higher number of dispensaries. At an individual level, patrons who identified as Black or Hispanic were associated with a lower likelihood of purchasing edibles when compared to patrons who identified as other non-White, non-Hispanic race/ethnicity. Place-based policies focused on regulating edible sales through dispensaries may be fruitful in influencing access to edibles. Additionally, social marketing campaigns may benefit from targeting both locations where edible purchases are more likely and populations who are more likely to purchase edibles.

    One of the problems that often arise in the fisheries sector is maintaining the quality. In the room temperature, the fish more quickly enter the phase of rigor mortis and lasted shorter. The retention of fresh fish can be extended by adding antibacterial compounds in the form of synthetic chemicals or natural ingredients. One of the safe natural ingredients used to extend the freshness of the fish is the edible coating. Edible coatings may be composed of hydrocolloid, lipids and composites. In the food industry surimi can be used as an ingredient to make edible packaging or better known in the form of edible film and protein-based edible coating. Edible film and potential coatings are used as packaging materials as they may affect food quality, food safety, and shelf life. Protein-based edible film have superior inhibitory and mechanical properties compared to polysaccharide-based ones. This is because protein contains 20 different amino acids and has most special characteristics that produce functional characteristics when compared with polysaccharides used as an ingredient in edible film and coating making most homopolymers.

    Edible insects are attracting growing interest as a sustainable source of protein for addition to processed meat and dairy products. The current study investigated the optimal method for protein extraction from mealworm larvae ( Tenebrio molitor ), cricket adults ( Gryllus bimaculatus ), and silkworm pupae ( Bombyx mori ), for use in further applications. After defatting with n-hexane for up to 48 h, sonication was applied for 1-20 min and the protein yield was measured. All samples showed a total residual fat percentage below 1.36%, and a 35% to 94% improvement in protein yield (%). In conclusion, defatting with n-hexane combined with sonication improves the protein yield from insect samples.

    The over increasing demand of eco-friendly materials to counter various problems, such as environmental issues, economics, sustainability, biodegradability, and biocompatibility, open up new fields of research highly focusing on nature-based products. Edible polymer based materials mainly consisting of polysaccharides, proteins, and lipids could be a prospective contender to handle such problems. Hydrogels based on edible polymer offer many valuable properties compared to their synthetic counterparts. Edible polymers can contribute to the reduction of environmental contamination, advance recyclability, provide sustainability, and thereby increase its applicability along with providing environmentally benign products. This review is highly emphasizing on toward the development of hydrogels from edible polymer, their classification, properties, chemical modification, and their potential applications. The application of edible polymer hydrogels covers many areas including the food industry, agricultural applications, drug delivery to tissue engineering in the biomedical field and provide more safe and attractive products in the pharmaceutical, agricultural, and environmental fields, etc.

    Kristiana, S. P. D.

    2017-12-01

    Corporate chain store is one type of retail industries companies that are developing growing rapidly in Indonesia. The competition between retail companies is very tight, so retailer companies should evaluate its performance continuously in order to survive. The selling price of products is one of the essential attributes and gets attention of many consumers where it’s used to evaluate the performance of the industry. This research aimed to determine optimal selling price of product with considering cost factors, namely purchase price of the product from supplier, holding costs, and transportation costs. Fuzzy logic approach is used in data processing with MATLAB software. Fuzzy logic is selected to solve the problem because this method can consider complexities factors. The result is a model of determination of the optimal selling price by considering three cost factors as inputs in the model. Calculating MAPE and model prediction ability for some products are used as validation and verification where the average value is 0.0525 for MAPE and 94.75% for prediction ability. The conclusion is this model can predict the selling price of up to 94.75%, so it can be used as tools for the corporate chain store in particular to determine the optimal selling price for its products.

Moreover, this machine exerts fuzzy control over stepper motor rpm, and the motor drives the conveyor belt with a scraper to scatter rice, deliver it, and keep it warm. Apart from an external 4*4 keyboard, a point of sale (POS machine, an ARM process and a pressure sensor, the machine is also equipped with card swiping and weighting mechanisms to achieve functions of card swiping payment and precise measurement, respectively. In addition, detection of the right amount of rice and the alarm function are achieved using an ultrasonic sensor and a beeper, respectively. The presence of the rice container on the rice outlet is detected by an optoelectronic switch. Results show that this rice-selling machine achieves precise measurement, quick card swiping, fast rice selling, stable operation, and good rice heat preservation. Therefore, the mechanical design enables the machine to achieve its goals.

    Full Text Available Fatigue is the symptom of tiredness caused by physical and/or psychological stresses. As fatigue is becoming a serious problem in the modern society affecting human health, work efficiency, and quality of life, effective antifatigue remedies other than pharmacological drugs or therapies are highly needed. Mushrooms have been widely used as health foods, because of their various bioactive constituents such as polysaccharides, proteins, vitamins, minerals, and dietary fiber. This paper reviews the major findings from previous studies on the antifatigue effects, the active components of mushrooms, and the possible mechanisms. Many studies have demonstrated the antifatigue effects of edible and medicinal mushrooms. These mushrooms probably mitigate human fatigue through effects on the functional systems, including the muscular, cardiovascular, hormone, and immune system. The bioactive constituents that contribute to the antifatigue effects of mushrooms may include polysaccharides, peptides, nucleosides, phenolic compounds, and triterpenoids. Further research is still needed to identify the active ingredients and to investigate their mechanism of action on the antifatigue effects. Since most previous studies have been carried out in animal models, more human trials should be performed to verify the antifatigue function of edible and medicinal mushrooms.

    Full Text Available Currently, nanotechnology represents an important tool and an efficient option for extending the shelf life of foods. Reducing particle size to nanometric scale gives materials distinct and improved properties compared to larger systems. For food applications, this technology allows the incorporation of hydrophilic and lipophilic substances with antimicrobial and antioxidant properties that can be released during storage periods to increase the shelf life of diverse products, including whole and fresh-cut fruits and vegetables, nuts, seeds, and cheese, among others. Edible coatings are usually prepared with natural polymers that are non-toxic, economical, and readily available. Nanosystems, in contrast, may also be prepared with biodegradable synthetic polymers, and liquid and solid lipids at room temperature. In this review, recent developments in the use of such nanosystems as nanoparticles, nanotubes, nanocomposites, and nanoemulsions, are discussed critically. The use of polymers as the support matrix for nanodispersions to form edible coatings for food preservation is also analyzed, but the central purpose of the article is to describe available information on nanosystems and their use in different food substrates to help formulators in their work.

    Edible blueberry species are well recognized for their potential health benefits. Ericaceae fruits including the North American highbush blueberry (Vaccinium corymbosum L.) and five less common edible blueberry relatives from the New World tropics, Anthopterus wardii Ball, Cavendishia grandifolia Hoerld, Macleania coccoloboides A. C. Sm., Sphyrospermum buxifolium Poepp. & Endl., and Sphyrospermum cordifolium Benth, were investigated for their antioxidant properties and phenolic profiles. The Neotropical berries C. grandifolia and A. wardii exhibited significantly higher DPPH• and ABTS•+ scavenging and iron chelation activities than V. corymbosum. Total phenolic content and HPLC-PDA compositional fingerprint analyses were also carried out. Significant correlations were observed among total phenolic contents, DPPH• and ABTS•+ scavenging, and iron chelation activities. Using HPLC-PDA, the phenolic constituents in the berries were identified as chlorogenic acid, p-coumaric acid, hyperoside, quercetin-3-O-glucoside, isoorientin, isovitexin, orientin and vitexin. Principal components analysis reduced the dimensions of antioxidant and total phenolic data to two components, which accounted for 95% of total variation among the six fruits. Each fruit species formed its own cluster, and therefore the antioxidant profile of each species was shown to be distinct. PMID:21391608

  18. Antifungal Edible Coatings for Fresh Citrus Fruit: A Review

    2015-12-01

    Full Text Available According to their origin, major postharvest losses of citrus fruit are caused by weight loss, fungal diseases, physiological disorders, and quarantine pests. Cold storage and postharvest treatments with conventional chemical fungicides, synthetic waxes, or combinations of them are commonly used to minimize postharvest losses. However, the repeated application of these treatments has led to important problems such as health and environmental issues associated with fungicide residues or waxes containing ammoniacal compounds, or the proliferation of resistant pathogenic fungal strains. There is, therefore, an increasing need to find non-polluting alternatives to be used as part of integrated disease management (IDM programs for preservation of fresh citrus fruit. Among them, the development of novel natural edible films and coatings with antimicrobial properties is a technological challenge for the industry and a very active research field worldwide. Chitosan and other edible coatings formulated by adding antifungal agents to composite emulsions based on polysaccharides or proteins and lipids are reviewed in this article. The most important antifungal ingredients are selected for their ability to control major citrus postharvest diseases like green and blue molds, caused by Penicillium digitatum and Penicillium italicum, respectively, and include low-toxicity or natural chemicals such as food additives, generally recognized as safe (GRAS compounds, plant extracts, or essential oils, and biological control agents such as some antagonistic strains of yeasts or bacteria.

  19. Environmental manipulation for edible insect procurement: a historical perspective

    2012-01-01

    Throughout history humans have manipulated their natural environment for an increased predictability and availability of plant and animal resources. Research on prehistoric diets increasingly includes small game, but edible insects receive minimal attention. Using the anthropological and archaeological literature we show and hypothesize about the existence of such environmental manipulations related to the procurement of edible insects. As examples we use eggs of aquatic Hemiptera in Mexico which are semi-cultivated by water management and by providing egg laying sites; palm weevil larvae in the Amazon Basin, tropical Africa, and New Guinea of which the collection is facilitated by manipulating host tree distribution and abundance and which are semi-cultivated by deliberately cutting palm trees at a chosen time at a chosen location; and arboreal, foliage consuming caterpillars in sub-Saharan Africa for which the collection is facilitated by manipulating host tree distribution and abundance, shifting cultivation, fire regimes, host tree preservation, and manually introducing caterpillars to a designated area. These manipulations improve insect exploitation by increasing their predictability and availability, and most likely have an ancient origin. PMID:22264307

    Full Text Available Edible black ant (Polyrhachis vicina Roger is a traditional edible insect species in China. It has been used as a functional ingredient in various tonics or health foods. This study determined the nutritional composition of the black ant, which included minerals, amino acids, superoxide dismutase (SOD, Vitamin E, and total acid. Supercritical CO2 fluid extraction was used to extract the organic compounds. The compounds were identified and quantified by GC-MS. Results showed that the ant powder contained 77000 IU/100g of SOD, 56.6g/100g protein, 9.0g/100g fat, 13.2g/100g volatile oil, 6.0g/100g moisture, 1.6g/100g total acid and 6.3g/100g ash. There were 18 amino acids, of which, glutamic acid, glycine, aspartic acid, alanine, leucine, proline and tyrosine were predominant. Among the 16 minerals, K, Ca, P, Mg, Fe, Mn and Zn were predominant. More than 20 organic components were identified, the main ones were 9-octadecenoic acid, ethyl oleate, cholesterol and n-hexadecanoic acid. Six of the compounds found, i.e. hexadecanoic acid, ethyl ester, linoleic acid, ethyl oleate, oleic acid and cholesta-3, 5-diene, have not been reported previously. The results indicate that P. vicina Roger is rich in nutrients and is a potential ingredient for health food.

    The objective of this study was to evaluate the potential of oil-rich green algae, Chlorella vulgaris, Scenedesmus obliquus, and Nannochloropsis oceanica, to produce edible oil with respect to lipid and residue properties. The results showed that C. vulgaris and N. oceanica had similarly much higher lipid recovery (about 50 %) in hexane extraction than that of S. obliquus (about 25 %), and C. vulgaris had the highest content of neutral lipids among the three algae. The fatty acid compositions of neutral lipids from C. vulgaris and S. obliquus were mainly C16 and C18, resembling that of vegetable oils. ARA and EPA were the specific valuable fatty acids in lipids of N. oceanica, but the content of which was lower in neutral lipids. Phytol was identified as the major unsaponifiable component in lipids of the three algae. Combined with the evaluation of the ratios in SFA/MUFA/PUFA, (n-6):(n-3) and content of free fatty acids, lipids obtained from C. vulgaris displayed the great potential for edible oil production. Lipids of N. oceanica showed the highest antioxidant activity, and its residue contained the largest amounts of protein as well as the amino acid compositions were greatly beneficial to the health of human beings.

    Thermal properties of several edible oils such as olive, sesame, and grape seed oils were obtained by using the photopyroelectric technique. The inverse photopyroelectric configuration was used in order to obtain the thermal effusivity of the oil samples. The theoretical equation for the photopyroelectric signal in this configuration, as a function of the incident light modulation frequency, was fitted to the experimental data in order to obtain the thermal effusivity of these samples. Also, the back photopyroelectric configuration was used to obtain the thermal diffusivity of these oils; this thermal parameter was obtained by fitting the theoretical equation for this configuration, as a function of the sample thickness (called the thermal wave resonator cavity), to the experimental data. All measurements were done at room temperature. A complete thermal characterization of these edible oils was achieved by the relationship between the obtained thermal diffusivities and thermal effusivities with their thermal conductivities and volumetric heat capacities. The obtained results are in agreement with the thermal properties reported for the case of the olive oil.

    Edible films and coatings have been proposed as viable alternatives for the preservation of fresh food such as fruit, meat, fish and cheese. They can be designed to contain natural antioxidants, vitamins and antimicrobials in order to extend shelf life of the product keeping the natural sensorial properties. Essential oils have been targeted as potential active principles for edible films and coatings given their well-recognized antioxidant, antimicrobial and sensory properties. In the present work, lemongrass oil (LMO) microcapsules were prepared by the emulsification-separation method using sodium caseinate as wall material. Microcapsules had an average size of 22 μm and contained over 51 % oil in their nucleus. The release kinetics of the LMO components was studied for both, microcapsules and microcapsule containing films. Experimental data for the controlled release of LMO components showed good correlation with Peppas and Weibull models. The effect of the alginate matrix on the release parameters of the mathematical models could be detected by the modification of the b constant of the Weibull equation which changed from 0.167 for the microcapsules to 0.351 for the films. Films containing LMO at concentrations of 1250, 2500 and 5000 ppm were able to inhibit growth of Escherichia coli ATCC 25922 and Listeria monocytogenes ISP 65-08 in liquid cultures. A possible future application of these films for shelf life extension of fresh food is discussed.

    In this article, we extend the classical economic production quantity (EPQ) model by proposing imperfect production processes and quality-dependent unit production cost. The demand rate is described by any convex decreasing function of the selling price. In addition, we allow for shortages and a time-proportional backlogging rate. For any given selling price, we first prove that the optimal production schedule not only exists but also is unique. Next, we show that the total profit per unit time is a concave function of price when the production schedule is given. We then provide a simple algorithm to find the optimal selling price and production schedule for the proposed model. Finally, we use a couple of numerical examples to illustrate the algorithm and conclude this article with suggestions for possible future research.

    Using Pittsburgh Youth Study data, we examined the extent to which over 600 gang members and non-gang involved young men specialized in drug selling, serious theft, or serious violence or engaged simultaneously in these serious delinquent behaviors, throughout the 1990s. We found that the increase in delinquency associated with gang membership was concentrated in two combinations: serious violence and drug selling; serious violence, drug selling, and serious theft. Several covariates were similarly associated with multi-type serious delinquency and gang membership (age, historical time, Black race, and residential mobility), suggesting that these behaviors may share common developmental, familial, and contextual risks. We encourage future research to further examine the association of gang membership with engagement in particular configurations of serious delinquency.

    The requirement for smooth information such as buying and selling is essential for commodity warehouse receipt system such as dried seaweed and their stakeholders to transact for an operational transaction. Transactions of buying or selling a commodity warehouse receipt system are a risky process due to the fluctuations in dynamic commodity prices. An integrated system to determine the condition of the real time was needed to make a decision-making transaction by the owner or prospective buyer. The primary motivation of this study is to propose computational methods to trace market tendency for either buying or selling processes. The empirical results reveal that feature selection gain ratio and k-NN outperforms other forecasting models, implying that the proposed approach is a promising alternative to the stock market tendency of warehouse receipt document exploration with accurate level rate is 95.03%.

    Full Text Available In today’s competitive markets, selling price and purchasing cost are usually fluctuating with economic conditions. Both selling price and purchasing cost are vital to the profitability of a firm. Therefore, in this paper, I extend the inventory model introduced by Teng and Yang (2004 to allow for not only the selling price but also the purchasing cost to change from one replenishment cycle to another during a finite time horizon. The objective is to find the optimal replenishment schedule and pricing policy to obtain the profit as maximum as possible. The conditions that lead to a maximizing solution guarantee that the existence, uniqueness, and global optimality are proposed. An efficient solution procedure and some theoretical results are presented. Finally, numerical examples for illustration and sensitivity analysis for managerial decision making are also performed.

    2011-11-01

    Full Text Available Abstract Background Wild food plants are a critical component in the subsistence system of rice farmers in Northeast Thailand. One of the important characteristics of wild plant foods among farming households is that the main collection locations are increasingly from anthropogenic ecosystems such as agricultural areas rather than pristine ecosystems. This paper provides selected results from a study of wild food conducted in several villages in Northeast Thailand. A complete botanical inventory of wild food plants from these communities and surrounding areas is provided including their diversity of growth forms, the different anthropogenic locations were these species grow and the multiplicity of uses they have. Methods Data was collected using focus groups and key informant interviews with women locally recognized as knowledgeable about contemporarily gathered plants. Plant species were identified by local taxonomists. Results A total of 87 wild food plants, belonging to 47 families were reported, mainly trees, herbs (terrestrial and aquatic and climbers. Rice fields constitute the most important growth location where 70% of the plants are found, followed by secondary woody areas and home gardens. The majority of species (80% can be found in multiple growth locations, which is partly explained by villagers moving selected species from one place to another and engaging in different degrees of management. Wild food plants have multiple edible parts varying from reproductive structures to vegetative organs. More than two thirds of species are reported as having diverse additional uses and more than half of them are also regarded as medicine. Conclusions This study shows the remarkable importance of anthropogenic areas in providing wild food plants. This is reflected in the great diversity of species found, contributing to the food and nutritional security of rice farmers in Northeast Thailand.

  14. The use of wild plants as food in pre-industrial Sweden

    2012-12-01

    Full Text Available This paper is a review of the actual gathering and use of wild edible plants in the 18th and 19th centuries, with a brief concluding discussion on the present day use of wild plants as food within Sweden. The peasants and the nomads in pre-industrial Sweden utilised very few wild plant taxa as food. Many even despised the wild fruits and green plants. Some plants and fruits were earlier mostly eaten fresh on the spot, or gathered for consumption in bread, gruel or soup. Other fruits were dried or preserved in other ways. In times of food shortages the amount of wild plants increased in the diet, but still the peasantry and nomads were often able to use fish and game to provide enough nutrients. With access to cheap sugar in the early 20th century wild fruits (Vaccinium myrtillus L., V. vitis-idaea L., and Rubus chamaemorus L. increased in importance, especially among urban-dwellers and within food industry. In the last few decades fungi have also become part of the urban diet. Fifty years ago working class people gathered only Cantharellus cibarius (Fr. and occasionally Boletus edulis Bull. Nowadays more taxa are utilised within the Swedish households, and especially the easy to pick Cantharellus tubaeformis (Pers. has become very popular recently. Harvesting fruits and mushrooms in the forests is a popular pastime for many urban people, but also a source of income for immigrants and especially foreign seasonal labour. The only traditional green wild food plant that is regularly eaten in contemporary Sweden is Urtica dioica L.

    2013-01-01

    Objective To determine the prevalence of phosphorus-containing food additives in best selling processed grocery products and to compare the phosphorus content of a subset of top selling foods with and without phosphorus additives. Design The labels of 2394 best selling branded grocery products in northeast Ohio were reviewed for phosphorus additives. The top 5 best selling products containing phosphorus additives from each food category were matched with similar products without phosphorus additives and analyzed for phosphorus content. Four days of sample meals consisting of foods with and without phosphorus additives were created and daily phosphorus and pricing differentials were computed. Setting Northeast Ohio Main outcome measures Presence of phosphorus-containing food additives, phosphorus content Results 44% of the best selling grocery items contained phosphorus additives. The additives were particularly common in prepared frozen foods (72%), dry food mixes (70%), packaged meat (65%), bread & baked goods (57%), soup (54%), and yogurt (51%) categories. Phosphorus additive containing foods averaged 67 mg phosphorus/100 gm more than matched non-additive containing foods (p=.03). Sample meals comprised mostly of phosphorus additive-containing foods had 736 mg more phosphorus per day compared to meals consisting of only additive-free foods. Phosphorus additive-free meals cost an average of $2.00 more per day. Conclusion Phosphorus additives are common in best selling processed groceries and contribute significantly to their phosphorus content. Moreover, phosphorus additive foods are less costly than phosphorus additive-free foods. As a result, persons with chronic kidney disease may purchase these popular low-cost groceries and unknowingly increase their intake of highly bioavailable phosphorus. PMID:23402914

Phosphorus additive-free meals cost an average of $2.00 more per day. Phosphorus additives are common in best-selling processed groceries and contribute significantly to their phosphorus content. Moreover, phosphorus additive foods are less costly than phosphorus additive-free foods. As a result, persons with chronic kidney disease may purchase these popular low-cost groceries and unknowingly increase their intake of highly bioavailable phosphorus.

    There is evidence that wide distribution of cigarettes contributes to smoking, and multiple commentators have called for a review of tobacco retailing. This study analyses retailers who stop selling cigarettes, why they do so, and discusses the implications for tobacco control. An audit of tobacco retailers in the Australian state of NSW was used to identify retailers who had stopped selling tobacco, and they were then compared with current retailers to determine how many, and what types of outlets stop selling tobacco. Attempts were made to contact and interview all former tobacco retailers identified in three audited regions. In-depth interviews were conducted with 13 ex-tobacco retailers, or 31% of the subset of ex-tobacco retailers. Low-volume outlet types were over-represented as a proportion of retailers exiting the market, and some had resumed selling within 18 months of the audit. Low profits were often cited as a contributor to stopping; however, in all but one case, the decision to stop selling was also influenced by a significant change in business circumstances-either legislative or other business changes. Few retailers stop selling tobacco while continuing in the same business, and those who stop disproportionately represent retailer types with low sales volume. The results suggest that legislative changes provide a window where retailers could be prompted to exit the market. Published by the BMJ Publishing Group Limited.

  18. Economic forces push down selling prices of U.S. refineries

    International Nuclear Information System (INIS)

    Anon.

    1996-01-01

    Recent data on US refinery sales reveal that selling prices have continued to decline in the 1990s. Reasons for this decrease include increased plant investments to meet regulatory requirements, excess refining capacity, increased imports of refined products, and reduced margins. While these expenditures enable a refinery to continue operating, they do not make the refinery more profitable or valuable. Other factors contributing to reduced selling prices of US refineries are: declining local crude production; unstable crude costs; increased energy conservation; growing competition from alternative fuels

    2009-01-01

    Wild lettuce (Lactuca virosa) can cause toxic effects when eaten. Wild lettuce grows in the north of Iran and some natives consume it unaware of its adverse side effects. We describe eight patients with manifestations of wild lettuce toxicity, admitted to a general hospital affiliated to the Golestan University of Medical Sciences. All the patients recovered (although one had to spend 48 h in the intensive care unit) and no chronic complications were reported. A clinical suspicion of toxicity caused by wild lettuce intake and an accurate history formed the basis of the diagnosis. Conservative treatment, vital sign monitoring, control of patient intake and output, and reducing patient agitation provided the basis for treatment.

    2013-04-19

    Many wild and cultivated plants are rich in mineral elements and bioactive compounds and are consumed for health purposes. Studies have demonstrated the curative properties of many of these food plants. In this paper, we discuss the properties of several plants with potential health benefits that have previously received little attention. This review provides an overview and critical discussion of food plants perceived by informants (emic view) as healthy or used as 'food medicine' in Italy. Pharmacological activity of these plants is explored, based upon published scientific research (etic view). Preparation methods, taste perception, toxicity and various potentialities of some food plants are also discussed. The present review includes literature available from 1877 to 2012. The information was collected from books, scientific papers, and abstracts that reported any plants used as food medicine in Italy. The perceived health properties were analyzed in the framework of recent international phytochemical and phytopharmacological literature. A total of 67 edible wild plants and 18 cultivated vegetables, distributed into 20 families, were reported by informants (in literature). Several plants were highly cited (e.g., Taraxacum officinale Webb., Crepis vesicaria L., Allium cepa L., Allium sativum L.). The most frequent health properties attributed to edible plants by the informants were: laxative (22 species), diuretic (15), digestive (11), galactagogue (8), antitussive (cough) (8), hypotensive (7), tonic (7), sedative (7), hypoglycemic (6). Some edible plants are promising for their potential health properties, such as Crepis vesicaria L., Sanguisorba minor Scop. and Sonchus oleraceus L. Several wild species were perceived by informants to maintain health but have never been studied from a phytochemical or pharmacological point of view: e.g., Asparagus albus L., Crepis leontodontoides All., Hyoseris radiata L. subsp. radiata, Phyteuma spicatum L.

    2011-12-01

    Full Text Available The studies of Allen (2011 and Allen et al. (2011 recently examined the methodology underpinning claims that dingoes provide net benefits to biodiversity by suppressing foxes and cats. They found most studies to have design flaws and/or observational methods that preclude valid interpretations from the data, describing most of the current literature as ‘wild dogma’. In this short supplement, we briefly highlight the roles and implications of wild dogma for wild dog management in Australia. We discuss nomenclature, and the influence that unreliable science can have on policy and practice changes related to apex predator management [Current Zoology 57 (6: 737–740, 2011].

    One of fruit preservation method is by applying the edible coating. Rind of passion fruit (Passiflora edulis var. flavicarpa Degener), which is kind of waste, can be utilized as edible coating through pectin extraction process. The purposes of this work were to determine the suitable solvent for the pectin extraction and techniques for applying the produced edible coating on strawberry, to produce edible coating from the pectin, and the test the performance of the edible coating which was applied to strawberries. Pectin from passion fruit rind was collected through conventional extraction method using two types of solvent, i.e. acetic acid solution and hydrochloric acid solution with concentration of 0.01 N, 0.015 N, 0.02 N, 0.025 N, and 0.03 N. The results showed that chloric acid solution was more suitable for the pectin extraction from passion fruit. Maximum yield of 30.78% was obtained at hydrochloric acid concentration of 0.02 N. Obtained pectin from the extraction was then processed into the edible coating by adding plasticizers and calcium chloride dihydrate. Storability of the coated strawberry was observed to measure the performance of the edible coating

    The use of edible films and coatings is an environmentally friendly technology that offers substantial advantages for shelf-life increase of many food products including fruits and vegetables. The development of new natural edible films and coatings with the addition of antimicrobial compounds to preserve fresh and minimally processed fruits and vegetables is a technological challenge for the industry and a very active research field worldwide. Antimicrobial agents have been successfully added to edible composite films and coatings based on polysaccharides or proteins such as starch, cellulose derivatives, chitosan, alginate, fruit puree, whey protein isolated, soy protein, egg albumen, wheat gluten, or sodium caseinate. This paper reviews the development of edible films and coatings with antimicrobial activity, typically through the incorporation of antimicrobial food additives as ingredients, the effect of these edible films on the control of target microorganisms, the influence of antimicrobial agents on mechanical and barrier properties of stand-alone edible films, and the effect of the application of antimicrobial edible coatings on the quality of fresh and fresh-cut fruits and vegetables.
