摘要
L-茶氨酸是茶叶中一种特殊的游离氨基酸,也是茶叶主要风味物质之一,因其具有放松心情、缓解疲劳、抗肿瘤、降血压等保健功能,被食品和医疗保健领域广泛关注。为了研究茶氨酸合成途径及方法,本文总结了目前L-茶氨酸合成的主要的途径,根据来源分为植物源合成和微生物源合成,根据合成方式分为生物酶法催化合成和化学方法合成,并分析了各个合成方法的优缺点,同时总结了L-茶氨酸在食品和医疗领域的应用,提出了高效合成茶氨酸未来的研究方向,以期为L-茶氨酸合成生产和应用提供参考。
L-theanine is a special free amino acid in tea leaves and one of the main flavor substances in tea.Due to its health benefits such as relaxation,fatigue relief,anti-tumor effects,and blood pressure reduction,it has received widespread attention in the food and healthcare industries.In order to study the synthesis pathway and methods of L-theanine,this paper summarized the current main pathways for L-theanine synthesis,which were divided into plant-derived synthesis and microbial-derived synthesis according to their sources;and bioenzymatic catalysis and chemical synthesis according to their synthesis methods.The advantages and disadvantages of each synthesis method were analyzed.Meanwhile,the applications of L-theanine in food and medical fields were summarized,and future research directions for efficient theanine synthesis were proposed,aiming to provide a reference for the production and application of L-theanine.
