糖代谢调控杨梅果实采后抗氧化活性机制研究进展

杨梅果实中天然抗氧化物质对人类健康的作用日益受到人们的重视, 抗氧化活性的大小已成为衡量果实采后品质的一个重要指标, 维持和提高果实采后抗氧化能力已成为果实采后贮运保鲜研究中的热点。糖代谢是果实采后主要的生理活动之一, 与果实采后花色苷和酚类物质的代谢存在密切的联系。本文简要介绍了杨梅果实的抗氧化特性, 重点综述了糖代谢调控果实采后抗氧化活性机制的研究进展, 提出了糖代谢调控杨梅果实采后花色苷和酚类物质合成代谢机制的研究展望。

Progress on carbohydrate metabolism regulating antioxidant capacity of postharvest Chinese bayberry fruit

There are accumulated data indicating that the natural antioxidant compounds from Chinese bayberry fruits have biological properties which can enhance human health. Since antioxidant capacity is becoming an important quality parameter for postharvest fruit, it is focusing on maintaining and improvement of antioxidant activity in fruit during postharvest storage. Carbohydrate metabolism is one of the most important physiological activities of postharvest fruit, and is also closely related to the biosynthesis and metabolism of anthocyanin and phenolic. This paper introduced the antioxidant properties of postharvest Chinese bayberry fruit, and focused on the research progress of carbohydrate metabolism regulating antioxidant capacity in postharvest Chinese bayberry fruit. Moreover, this paper also indicated the future research highlights to the specific mechanism of carbohydrate metabolism in the biosynthesis and metabolism of anthocyanin and phenolic in bayberry fruit.
