摘　　要：四氢嘧啶是一种保护性相容性溶质,可以保护生物大分子和细胞免受高温、极端pH、干燥、冷冻、辐射等不利环境条件的影响。因此,四氢嘧啶可用于新型食品添加剂的开发,广泛应用于食品生产加工过程中的酶保护、发酵菌体保护、食品保质期延长以及功能性食品开发等方面。基于近年来国内外的研究现状,综述了四氢嘧啶的生物合成-降解途径、生物保护作用机制及其应用,重点介绍了其在食品领域的应用,以期为四氢嘧啶类相容性溶质在食品领域的研究、开发和应用提供参考。Ectoine is a protective compatible solute,and can protect biomacromolecules and cells from adverse environmental conditions such as high temperature,extreme pH,drying,freezing,radiation and so on.Therefore,ectoine can be used in the development of new food additives,and can be widely used in enzyme protection,fermentation bacteria protection,food shelf life extension and functional food development and other aspects during food production and processing.Based on the research status at home and abroad in recent years,the biosynthesis-degradation pathway,bioprotection mechanism and application of ectoine have been discussed,with emphasis on its application in food field,in order to provide references for the research,development and application of ectoine compatible solutes in food field.
