农村食品安全现状·存在的问题及“质量大堤”的构建

作为食品原料的供应基地,食品消费的大市场,农村的食品质量关系着千家万户的身体健康和生命安全.农村食品安全问题的频发是一个经济、道德、社会、立法和监管各种因素综合作用的结果.农村食品安全“质量大堤”的构建依赖于德法并济的约束、食品安全知识的宣传和有效监管制度的实施.     

太白“全国奥运绿色食品(蔬菜)直供基地”建设的思考

解读《2008北京奥运食品安全行动纲要》对奥运食品原料定点供应基地的要求;概述了太白县蔬菜产品在通过国家绿色食品A级、USDA及EU有机食品认证后,"太白山"牌蔬菜产销两旺,2007年被确定为奥运会绿色蔬菜直供基地。由此启发思考,提出了围绕发展现代农业和"一村一品"建设,策应奥运食品安全追溯系统,突出技术标准化、产品销售品牌化、经营管理组织化、特色农业产业化,进一步促进"太白山"牌蔬菜产业提质增效优化升级的对策建议。     

河北启动奥运食品专项整治行动

河北省在全省范围内开展迎奥运食品专项整治行动,以确保奥运食品安全。 河北省环绕京津,是北京肉、蛋、奶、蔬菜等食品的主要供应基地,秦皇岛又是奥运会协办城市之一。目前,河北省直接供应奥运会食品企业有30多家,产品销往北京等赛事承办城市的食品企业有1000多家,分布在北京周边旅游景点和交通干线的食品企业和作坊有10000多家。

保障食品安全的供应组织模式

随着经济全球化进程的不断加快、居民收入水平的不断提高,食品安全问题越来越引起全世界的广泛关注.选择可靠、高效的食品供应组织,是保障食品安全的重要措施之一.借鉴发达国家的成功经验,结合我国的国情,三种比较成功的食品供应组织模式可以选择,包括农民销售合作组织、贸工农一体化经营组织和食品供应链物流管理模式等.     

我国食品安全现状及发展对策

近年来,我国食品安全事件频发,食品安全现状不容乐观.食品原料疏于控制、食品加工操作不规范,市场监督力度不强是主要原因.今后,应采取提高全民食品安全意识,健全和完善食品生产的法则,积极推广以HACCP为核心的ISO 22000食品安全管理体系,建立食品完全信息发布制度等对策来解决我国食品安全问题.     

植物基因工程与食品改良

食品是人类生存与发展的重要物质基础.做为食品加工主要原料的农作物,人们对其在营养品质、耐贮藏性和加工特性等方面,提出了更高的要求,植物基因工程在此方面发挥着越来越重要的作用.植物基因工程使得食品工业在原材料供应和原材料种类的选择上更为自由.目前它在食品改良上的应用尚处于初级阶级,但随着基因工程技术的发展及食品安全卫生管理规范的逐步完善,将会有更多种类的“遗传工程食品”奉献给人类.     

食品安全问题探析

目前食品安全已成为全社会关注的焦点,食品安全问题主要表现在食品源头污染,如农药残留、化肥滥用、兽药残留、重金属污染、生物毒素、转基因食品、食品掺假、食品投毒等.虽然我国出台了相关法律法规,但有些规定滞后于目前的社会生活与经济发展,很多方面的规定不够具体,针对性不强.提出了明确监管职责、界定食品生产者和销售者的法律责任、对食品生产企业实施质量体系认证、完善现行食品安全标准、建立和完善食品安全预警预报机制、建立食品安全社会信用体系等食品安全保障体系的建议.     

食品添加剂对食品安全的影响

该文阐述了食品添加剂与食品安全的概念,介绍了食品添加剂对食品安全的影响,探讨了如何提高食品安全及降低食品添加剂对人体健康的影响.     

Animals respond for food in the presence of free food

Pigeons pecked a response disk to gain access to grain rewards while identical grain was freely available from a cup within the experimental chamber. Similarly, rats pressed a lever for food pellets while free pellets were present. It is not necessary, therefore, to deprive an animal of food before it will engage in instrumental responding for food. Such responding can serve as its own motivation and reward.     

Rights-based food systems and the goals of food systems reform

Food security, health, decent livelihoods, gender equity, safe working conditions, cultural identity and participation in cultural life are basic human rights that can be achieved at least in part through the food system. But current trends in the US prevent full realization of these economic, social, and cultural rights (ESCR) for residents, farmers, and wageworkers in the food system. Supply chains that strive to meet the goals of social justice, economic equity, and environmental quality better than the dominant globalized food value networks are gaining popularity in the US. However, achieving important human rights has become conflated with other goals of food system reform over the past decade, such as being “community-based,” local, and sustainable. This conflation confuses means, ends, and complementary goals; and it may lead activists trying to help communities to regain control of their food system choices into less productive strategies. This paper introduces a new concept, rights-based food systems (RBFS), and explores its connection with localization and sustainability. The core criteria of RBFS are democratic participation in food system choices affecting more than one sector; fair, transparent access by producers to all necessary resources for food production and marketing; multiple independent buyers; absence of human exploitation; absence of resource exploitation; and no impingement on the ability of people in other locales to meet this set of criteria. Localization and a community base can help achieve RBFS by facilitating food democracy and reducing environmental exploitation, primarily by lowering environmental costs due to long-distance transportation. Sustainability per se is an empty goal for food system reform, unless what will be sustained and for whom are specified. The RBFS concept helps to clarify what is worth sustaining and who is most susceptible to neglect in attempts to reform food systems. Localization can be a means toward sustainability if local food systems are also RBFS.

Air pollution,food production and food security: A review from the perspective of food system

Air pollution negatively impacts food security. This paper reviews the current literature on the relationship between air pollution and food security from the perspective of food system. It highlights that agricultural emissions which substantially contribute to air pollution could happen at every stage along the food supply chain. Meanwhile, air pollution can not only affect plant growth and animal health but also shift market equilibrium of both agro-inputs and outputs in the food supply chain and thereby affect food security indirectly. Furthermore, this study evaluates the effects of agricultural policy and energy policy on food security and air pollution, respectively, and provides an overview of potential policy instruments to reduce air pollution while ensuring food security. Finally, we identify the remaining research and policy issues for further studies, mainly focusing on the study of household's bounded rational behaviors and the issue of rural aging population.     

食品包装材料中邻苯二甲酸酯向食品模拟物中的迁移规律

采用超高效液相-串联质谱法(UPLC-MS/MS)对不同温度、时间条件下的16种邻苯二甲酸酯(PAEs)从食品包装材料中向水性、酸性、酒性与脂肪性食品模拟物中的迁移律进行研究。结果表明:在食品模拟物富集浓度30μg/m L,富集时间6 h条件下,PAEs富集最佳。其中PAEs在不同食品模拟物中迁移率为:脂肪性酒性酸性水性;在同一种食品模拟物条件下,随着迁移时间增长和温度增加都有助于PAEs迁移速率提高;同时,同一性质食品模拟液在同一温度条件下,随着分子链长逐步增长,相对分子质量依次增大,迁移率基本呈逐渐降低趋势。
