微生物胺氧化酶研究进展

Advance in amine oxidase from microorganisms

胺氧化酶是一类有特殊生物功能的蛋白质,它能将生物胺降解为乙醛、氨、过氧化氢,从而可以减缓生物胺在食品中的危害。该文主要针对微生物所产的胺氧化酶的分类进行综述,根据辅助因子的不同将其分为含铜胺氧化酶和含黄素胺氧化酶,并从食品质量安全角度出发介绍了胺氧化酶在食品领域中的应用,最后展望了微生物胺氧化酶研究的前景。对微生物胺氧化酶种类的了解提供了依据,并对胺氧化酶在食品工业中应用提供了借鉴。

Amine oxidase is a protein which has special biological function. It can be degraded into acetaldehyde, ammonia and hydrogen peroxide, as for decreasing the harm ofbiogenic amines in food. The classification of amine oxidases produced by microorganisms were reviewed, according to the different cofactor, it can be divided into copper-containing amine oxidases and flavin-containing amine oxidase. Finally, from food quality and safety point of view, the application of amine oxidase in food field was introduced and the prospect of studying in microbial amine oxidase was made. A basis for understanding the classification of microbial amine oxidase, and reference for the application of amine oxidase in food industry were provided.
