摘要

酸茶作为一种厌氧发酵茶,具有独特的微生物群落和多种抗氧化活性物质。乳酸菌和酵母是酸茶发酵的优势菌群,不仅能够产生多种有机酸来提高酸茶抗氧化能力和风味品质,其自身也具有抗氧化性。大量的有机酸积累能够形成酸性发酵环境,从而减少表没食子儿茶素没食子酸酯(epigallocatechin gallate,EGCG)的水解和保持多酚含量的稳定。厌氧发酵还能够促进酸茶没食子酸的高含量积累和新型抗氧化成分的生成。该文综述了近年来酸茶厌氧发酵和抗氧化成分相关研究,为进一步研究酸茶抗氧化成分提供参考。

Abstract

Pickled tea is an anaerobically fermented tea with a distinct microbial community and numerous antioxidant substances. The primary substances generated during pickled tea fermentation are yeasts and lactic acid bacteria (LAB), which improve the antioxidant capacity and flavor of pickled tea by producing various organic acids. Yeasts and LABs also provide their own antioxidative properties. Organic acids create acidic fermentation conditions, thereby reducing the hydrolysis of EGCG and maintaining stable polyphenol levels. Moreover, anaerobic fermentation promotes high levels of gallic acid accumulation and the synthesis of novel antioxidant components. This article summarizes recent research into anaerobic fermentation and the antioxidant components of pickled tea and provides a reference for further investigations into the antioxidant substances in pickled tea.
