γ-氨基丁酸的生物合成及其在食品中的应用

Biological Function of γ-amino Butyric Acid and Its Application in the Food Industry

γ-氨基丁酸(GABA)是一种具有生物活性的非蛋白质氨基酸,因其生理功能强大及对代谢的积极影响而被广泛研究。其中最重要的是降压作用,已在动物和人体干预试验中得到验证。乳酸菌(LAB)是γ-氨基丁酸(GABA)的主要生产者,发酵食品中富含GABA。本文主要阐述了GABA的生物合成及其在食品中的应用。

Gamma-aminobutyric acid（ GABA） is a non-protein amino acid,considered a potent bioactive compound. GABA has been widely studied because of its numerous physiological functions and positive effects on many metabolic disorders. One the most important of these is the hypotensive effect that has been demonstrated in animals and in human intervention trials. Lactic acid bacteria（ LAB） are the main GABA-producers and therefore there are a wide range of GABA-enriched fermented food products. The application of GABA in food industry is introduced as well,and the paper forecasts the application of GABA in food industry.
