Spermidine, a natural autophagy inducer, has a variety of health effects, such as antitumor, antiaging, anti-inflammation, cardiovascular protection, and neuromodulation. It has been a hot topic in the field of food processing, and current research findings suggest that spermidine-rich foods may be used in intervention and prevention of age-related diseases. In this article, recent findings on the safety, health effects, absorption and metabolism of spermidine were reviewed, and advances in food processing, including the raw materials evaluation, physical and chemical processing, and biological processing of spermidine, were highlighted. In particular, the core metabolic pathways, key gene targets, and efficient metabolic engineering strategies involved in the biosynthesis of spermidine and its precursors were discussed. Moreover, limitations and future perspectives of spermidine research were proposed. The purpose of this review is to provide new insights on spermidine from its safety to its food processing, which will advance the commercial production and applications of spermidine-rich foods and nutraceuticals. 相似文献

Food safety issues have occurred frequently in China in recent years, which results in consumers’ high risk perception of food additives. In the present research, we examined whether knowledge would decrease Chinese consumers’ risk perception of food additives under the influence of food safety issues’ risk perception; we also investigated how information selection impacted popularization effectiveness. Study 1 demonstrated that risk perception of food safety issues was positively correlated with risk perception of food additives. In addition, with increased risk perception of food safety issues, the higher level of knowledge weakened the influence of risk perception of food safety issues on risk perception of food additives. In Study 2, we proposed a consumer-risk-focused approach of knowledge popularization related to food additives, based on consumers’ cognitive rules and concerns. We compared its popularization effectiveness with the comprehensive-knowledge-based approach at three time points. We found that the consumer-risk-focused approach significantly promoted the effectiveness of popularization, including increasing knowledge accuracy and trust, and decreasing risk perception. The present study provides evidence that risk perception of food safety issues leads to biased judgments and perceptions concerning food additives, but knowledge acts as a buffering function in this biased relationship. In addition, in terms of practical application, this study contributes to improving the effectiveness of knowledge popularization about food additives. 相似文献

在中国,食品物流行业还处于起步阶段,食品物流的基础设施建设、食品物流行业的规范化、食品冷冻链、食品物流信息技术方面已经取得很大进步。但是,中国食品物流行业仍然存在很多的问题,食品物流的基础设施还比较落后,食品物流的技术还欠发达,也未形成统一的食品行业规范,同时政府的监督以及企业组织的协调作用还远远没有发挥出来。为促进中国食品物流业务的不断发展,应当既要加大基础设施以及技术手段的资金投入力度,又要建立完善的现代统一的食品物流体系。同时还要不断完善食品物流安全的风险评估机制,并积极发挥政府及社会的风险防范作用。 相似文献

AbstractUmami taste is the most recent confirmed basic taste in addition to sour, sweet, bitter, and salty. It has been controversial because of its effects on human nutritional benefit. Based on the available literatures, this review categorized 13 positive and negative effects of umami taste on human health. On the positive side, umami taste can improve food flavor and consumption, improve nutrition intake of the elderly and patients, protect against duodenal cancer, reduce ingestion of sodium chloride, decrease consumption of fat, and improve oral functions. On the other hand, umami taste can also induce hepatotoxicity, cause asthma, induce migraine headaches, damage the nervous system, and promote obesity. Due to its novelty, there are many functions and effects of umami taste waiting to be discovered. With further investigation, more information regarding the effects of umami taste on human health will be discerned. 相似文献
