食品风味智能控释技术是指食品的风味成分通过对其在食品加工以及摄取过程的环境响应来控制其释放与否、释放速度以及释放程度。智能控释有利于食品风味在食品加工、储藏过程的稳定,也能使其充分赋予食品的功能属性。可应用于食品风味的智能控释技术包括微胶囊化技术、微球技术、纳米技术、脂质体技术、超分子形成法等。 相似文献

海洋磷脂因其独特的结构和生物活性引起人们的关注。海洋磷脂广泛存在于水产品中,由于多不饱和脂肪酸含量高,在加工和储运过程中易发生脂质氧化反应、非酶促褐变反应等,这一系列反应生成的产物一方面引起水产品的酸败,降低食品的品质;另一方面适当的磷脂氧化,提供了脂质来源的风味前体物质,是水产品特征香气物质产生的关键。在水产品的挥发性风味物质中已鉴定出醇、醛、2-戊基呋喃、苯甲醛等特征香气成分,此类风味物质的形成来源于脂质氧化以及非酶褐变等反应,受这些反应共同作用的影响,形成了食品独特诱人的品质和风味。该文综述了海洋磷脂氧化及其在食品风味中的作用,为深入理解食品特征风味物质形成提供参考。 相似文献

Most proteins are tasteless and flavorless, while some proteins elicit a sweet-taste response on the human palate. Six proteins, thaumatin, monellin, mabinlin, brazzein, egg lysozyme, and neoculin (previously considered as curculin) have been identified as sweet-tasting proteins. However, no common features among them have been observed. Herein, recent advances in the research of sweet-tasting proteins and the production of such proteins by biotechnological approaches are reviewed. Information on the structure-sweetness relationship for these proteins would help not only in the clarification of the mechanism of interaction of sweet-tasting proteins with their receptors, but also in the design of more effective low-calorie sweeteners. 相似文献

AbstractMicrobial exopolysaccharides (EPS) are an abundant and important group of compounds that can be secreted by bacteria, fungi and algae. The biotechnological production of these substances represents a faster alternative when compared to chemical and plant-derived production with the possibility of using industrial wastes as substrates, a feasible strategy after a comprehensive study of factors that may affect the synthesis by the chosen microorganism and desirable final product. Another possible difficulty could be the extraction and purification methods, a crucial part of the production of microbial polysaccharides, since different methods should be adopted. In this sense, this review aims to present the biotechnological production of microbial exopolysaccharides, exploring the production steps, optimization processes and current applications of these relevant bioproducts. 相似文献

微生物生态学技术制备天然香精香料 总被引:2,自引:0,他引:2
天然香精香料是高价值的精细化工产品和食品添加剂.但原料来源有限且提取成本高,利用生物技术生产这类产品具有广阔的前景.简述了发酵工程和酶工程在香精香料中的应用,并探讨了微生物生态学技术制备天然香精香料.植物内生菌是一个多样性十分丰富的微生物类群,分布于没有外在感染症状的健康植物组织内,并与宿主植物协同进化,其存在和作用长期以来一直为人们所忽视.现今我发现在某一植物内存在一稳定的微生物群落,它是由真菌、细菌、原生动物等组成.经研究与试验,发现将上述群落与某一些天然植物材料投放在封闭的发酵反应器中,在一定条件下,形成一生态系统.这一系统在发酵反应器中能制备天然香精香料.由于该群落的整体协同效应,可以利用各种天然植物材料来生产各种各样的天然香精香料,并且还能把微生物生态学技术与酶工程有机相结合,以牛乳为原料来生产天然牛乳香精. 相似文献

ABSTRACTSalvia miltiorrhiza (Danshen in Chinese), is a well-known traditional Chinese medicinal plant, which is used as not only human medicine but also health-promotion food. Danshen has been extensively used for the treatment of various cardiovascular and cerebrovascular diseases. As a major group of bioactive constituents from S. miltiorrhiza, water-soluble phenolic acids such as salvianolic acid B possessed good bioactivities including antioxidant, anti-inflammatory, anti-cancer and other health-promoting activities. It is of significance to improve the production of phenolic acids by modern biotechnology approaches to meet the increasing market demand. Significant progresses have been made in understanding the biosynthetic pathway and regulation mechanism of phenolic acids in S.miltiorrhiza, which will facilitate the process of targeted metabolic engineering or synthetic biology. Furthermore, multiple biotechnology methods such as in vitro culture, elicitation, hairy roots, endophytic fungi and bioreactors have been also used to obtain pharmaceutically active phenolic acids from S. miltiorrhiza. In this review, recent advances in bioactivities, biosynthetic pathway and biotechnological production of phenolic acid ingredients were summarized and future prospective was also discussed. 相似文献
