虾类保藏过程中酚氧化酶酶促黑变作用机理及其抑制方法的研究进展

Research progress in melanosis mechanism of shrimp products induced by phenoloxiade and the use of anti-melanosis techniques during preservation

在虾类贮藏过程中,虾体的黑变严重影响了虾的感官品质,酚氧化酶是催化酪氨酸等色原物质转化为黑色素造成虾体黑变的主要因素。文章综述了国内外酚氧化酶的形成机制研究现状,重点叙述了虾类中酚氧化酶的特性及抑制虾类黑变方法的研究进展,为虾类贮藏保鲜技术的研发与改进提供参考。

Melanosis in shrimp reduces the customers＇ acceptability drastically,leading to the decreasing of market values and considerable financial loss,which is triggered by a kind of enzymes called phenoloxidase.Phenoloxidase oxidizes tyrosine to quinine leading to black high molecular weight pigment.Studies on the mechanisms of phenoloxidase activation system and phenoloxidase inhibitory methods domestically and abroad were reviewed,in order to provide information for further study and development in shrimp preservation techniques.
