通过野外调查、标本鉴定和数据信息查询,对河北嶂石岩区域分布的野生油脂植物资源的种类、含油量及蕴藏量进行了统计和分析。结果表明:河北嶂石岩区域共有油脂植物39科72属79种,占嶂石岩区域植物总数的35.91%;在物种组成上,以唇形科、菊科、蔷薇科、十字花科和豆科为优势类群;在生活型上,以草本植物数量为多,木本植物较少,分别占油脂植物的51.90%和37.97%;在含油量上,以含油量在10%~20%之间的植物种类最多,另有近一半的植物含油量在30%以上;在油脂组成成分上,以富含亚油酸、亚麻酸等多不饱和脂肪酸的种类为主,占油脂植物的72.15%。唇形科、菊科、十字花科、豆科、松科和胡桃科等植物因蕴藏丰富、含油量高、应用前景广阔,可作为河北嶂石岩区域野生油脂植物优先开发的重点。 相似文献

Organically-certified wild plant foods are rarely addressed in scientific or public discourses on organic food even though 30% of the world’s organically-certified land is dedicated to wild plant gathering. This oversight may leave organic consumers unaware of the market relevance of wild plant foods. The aim of this study was therefore to understand organic consumers’ attitudes, knowledge and purchasing and gathering practices with respect to wild plant foods, and how sociodemographic variables and attitudes can predict knowledge and practices. A purposive sample was drawn from 22 urban and rural food markets across Austria and 497 organic consumers were interviewed using successive freelists and four-point Likert scale questions on attitudes. Data were analysed using exploratory factor analysis and multiple linear regressions. Organic consumers knew a median of nine wild food plants, and reported five as being gathered and one as being purchased. They valued food quality and the responsible harvest of wild food plants, but assigned them a low economic relevance, with some respondents sceptical about their suitability as food. Rural residence, a higher share of organic consumption and a greater emphasis on responsible harvesting predicted knowledge and gathering of a larger number of plant species. These results confirm that organic consumers know, gather and have positive attitudes with respect to wild plant foods, although they are hardly aware about their market relevance. We argue that consumers need to be better informed about the wild origin of food ingredients and the added value of organic certification of wild plant foods. 相似文献

Indigenous food ingredients for complementary food formulations to combat infant malnutrition in Benin: a review 下载免费PDF全文
Flora J Chadare Yann E Madode Nadia Fanou‐Fogny Janvier M Kindossi Juvencio OG Ayosso S Hermann Honfo AP Polycarpe Kayodé Anita R Linnemann D Joseph Hounhouigan 《Journal of the science of food and agriculture》2018,98(2):439-455
This paper reviews indigenous Beninese food resources as potential ingredients for complementary infant foods with the aim to develop affordable formulations for low‐income households in each agro‐ecological zone of the country. Potential ingredients were selected on their documented nutritional value. The selected foods encompass 347 food resources, namely 297 plant products from home gardens or collected from natural vegetation and 50 animals, either domesticated or from the wild. The compiled data reveal that the distribution of the available food resources was unbalanced between agro‐ecological zones. Only a few animal ingredients are obtainable in northern Benin. Most resources are seasonal, but their availability may be extended. A high variation was observed in energy and nutrient contents. Antinutritional factors were identified in some resources, but processing techniques were reported to reduce their presence in meals. In general, ingredients from local tree foods (Adansonia digitata, Parkia biglobosa) were adequate as sources of nutrients for complementary infant foods. Based on this review, local foods for the development of complementary food formulas for Beninese infants and children may be selected for each agro‐ecological zone. The approach used is exemplary for other sub‐Saharan African countries in need of complementary infant foods. © 2017 Society of Chemical Industry 相似文献
