农药最大残留限量标准是判别食品安全性的基础。研究农药最大残留限量标准制定过严可能产生的风险,对科学制定我国农药残留标准、保证食品安全和保护生态环境具有十分重要的现实意义。运用经济学的供求理论,从农户追求利润角度对农药残留标准制定过严可能产生的风险进行了深入分析。研究表明,在农产品质量信息不对称、市场监管不到位的情况下,农药最大残留限量标准制定过严,不但不能保护消费者身体健康和农业生态环境,反而有可能加剧农产品的农药残留问题泛滥。因此建议政府要尽快启动食品安全标准风险评估程序,合理评价农药最大残留限量标准的科学性,以消除食品安全管理隐患。 相似文献

近日,农业部与卫生部联合发布了食品安全国家标准《食品中农药最大残留限量》。作为我国监管食品中农药残留的唯一强制性国家标准,新标准制定了322种农药在十大类农产品和食品中的2293个残留限量。参与该标准制定的中国农药工业协会副秘书长曹承宇表示,与原来的标准相比,新标准覆盖范围更宽,标准更严,安全性更高。 相似文献

The Food for Peace Program of the U.S. Agency for International Development started in 1954 and will be continued even in time of short food supplies. The Food for Peace Program, the U.S. Department of Agriculture, and cooperating food processors developed technology for large scale production of soy grain blended foods. 相似文献

Food uses for cottonseed protein 总被引:1,自引:0,他引:1
Cottonseed, available in many countries located in both temperate and tropical climates, is rarely used as a source of edible
protein even though its use as food was suggested as carly as 1876. Development of edible protein products from cottonseed
has been impeded by the presence of gossypol-containing pigment glands in the kernels, and the economic value of the oil.
Cottonseed flour produced by mechanical pressing has been marketed in limited quantities as two edible protein products. One,
known as “Proflo,” is used primarily to impart functional characteristics to baked and confectionery products. The other is
used as an ingredient in “Incaparina” to combat malnutrition in Latin America. Because of the manner in which these cottonseed
protein products are processed, their full nutritional and functional potentials and versatiliity have not been realized.
Recent advances in breeding glandless cottonseed, processing glanded cottonseed (e.g., the liquid cyclone process), and related
technology have increased the potential of cottonseed protein for food uses. Flours, concentrates, and isolates differ qualitatively
and quantitatively in protein and amino acid composition. Consequently, they have different functional and nutritional characteristics
and end uses. Flours and concentrates as well as their texturized counterparts are acceptable as functional and nutritional
additives to meat products, baked goods, and cereals. Three isolates including storage protein, nonstorage protein, and a
mixture of both have been prepared from flours and concentrates. The storage protein isolate imparts functional characteristics,
such as texture, acid solubility and foam stability. The non-storage protein isolate has good nutritional characteristics
primarily because of its high lysine content. 相似文献

动物源性食品中抗生素残留检测技术研究进展 总被引:1,自引:0,他引:1
抗生素在禽畜业生产中的不合理使用现象非常普遍,其所造成的食品安全问题也较为严峻。抗生素残留检测是控制食品安全质量的重要环节,当前的抗生素残留检测方法主要是利用生物、化学工程中的一些分离与鉴别手段,实现对样品中目标组分的分离与鉴定。文章对当前抗生素检测的研究现状进行了梳理,分析了各种检测技术的优缺点,并对食品工业化抗生素检测技术的研究方向提出了建议。 相似文献
