摘要: 茶氨酸是绿茶中特有的一种氨基酸。50年代首次从茶叶中提取、精制出茶氨酸,并确定了它的化学结构,此后许多学者对其进行了大量的研究工作。包括在体内的吸收与代谢,检测方法,生理功能及在食品中的应用研究。茶氨酸主要作为食品添加剂,用于几乎所有食品中,除了改善食品风味外,还有多种保健功能,如降血压、抗疲劳,并对临床癌症患者的化疗有益。本文对茶氨酸的国内外最新研究进展进行了综述。

Abstract: Theanine is a peculiar amino acid in green tea.It was firstly extracted and refined from tea in 1950’s and its chemical structure was also determined at the same time.Since then many researchers have done a lot of studies on it,including its absorption and metabolism in vivo,detective method,biologicl effects and application to foods.Theanine could be in almost every kind of food,mainly as a food additive.It not only improves the food flavour,but also has health functions,such as reducing blood pressure,relieving fatigue and benefiting clinical chemotherapy.In this paper we summarized the latest research of theanine at home and abroad.
