Kokumi肽及其受体的研究进展
|
摘要
Kokumi是近年来新提出的继5种基本味觉(酸、甜、苦、咸、鲜)之后的第6种基本味觉,它主要代表食物的浓厚感、持续感和复杂感,符合人们对协调、圆润、平衡味感的需求。Kokumi肽是指本身不具备味道或呈味较淡,但添加少量即可增强其余5种味觉浓厚感和持续性的肽类物质。文章对kokumi肽的来源、序列特征、检测方法、酶合成方法、在食品中的应用及其味觉受体的识别机制研究现状进行了综述,以期为kokumi肽的理论研究和实际应用提供一定的参考。
Kokumi is the sixth basic taste reported in recent years,after the five basic tastes of sour,sweet,bitter,salty and umami.It mainly represents the richness,long-lasting and complexity of food,which meets the needs of people to the coordinated,rounded and balanced flavor.The kokumi peptides are the peptide substances which have no flavor or only a light flavor,but it could enhance the thick feeling and persistence of the other five kinds of basic tastes by a small additive amount.In this paper,the source,sequence characteristics,detection methods,enzyme synthesis methods,application of kokumi peptides in food and recognition mechanism of its taste receptors are reviewed,which provide a reference for the theoretical research and the practical application of kokumi peptides.
