褪黑素在浆果采后保鲜中应用研究进展

The Role and Application of Melatonin in Berries

褪黑素是一种多效性分子,在生物体中具有广泛的细胞和生理作用。作为一种两亲性的信号分子,可以自由地穿过细胞膜,增加细胞对自由基的抵抗力并提升细胞膜的稳定性,提高果蔬在采后的抗逆性、抗氧化能力和抗菌性,以延长其采后寿命及货架采后品质。本文概述了褪黑素对不同浆果自由基清除、延缓衰老、提升抗氧化性、抗胁迫能力方面的作用,并对其应用前景进行展望。

In organisms,melatonin plays a variety of cellular and physiological roles.As an amphiphilic signaling molecule,it can cross cell membranes freely,increasing the resistance of cells to free radicals and improving cell membrane stability,improve the stress resistance,antioxidant ability and antibacterial ability of fruits and vegetables in postharvest,so as to extend their postharvest life and shelf postharvest quality.In this paper,the effects of melatonin on free radical scavenging,delaying senescence,improving antioxidant and stress resistance of different berries were summarized,and its application prospects were prospected.
