蛋白质氧化与腊肉品质调控

材料写作网    时间: 2020-02-03 12:15:17     阅读:


  摘 要:氧化反应贯穿于整个腊肉加工过程,适度氧化能促进风味物质的形成,但过度氧化会导致腊肉发生哈败。蛋白质是腊肉的主要成分,在加工与贮藏过程中会发生一系列氧化变化,包括产生氧化标志产物、小分子挥发性物质,发生物理结构改变等,从而对腊肉的风味产生重要影响,但其氧化进程和作用机制并不明确。本文对蛋白质氧化机制、蛋白质氧化对肉类品质的影响、蛋白质氧化控制、腊肉中蛋白质氧化研究现状进行综述,为进一步开展研究,揭示腊肉中蛋白质氧化演变规律,阐明蛋白氧化在腊肉品质形成与保持中的作用机制,实现腊肉加工中氧化的精准控制提供参考。

  Abstract: Oxidative reaction occurs throughout the entire production process of Chinese bacon, which at moderate levels can promote the formation of flavor substances, but contrarily excessive oxidation may cause rancidity of Chinese bacon. As one of the main components, meat protein may be involved in a series of oxidative reactions to produce oxidation markers, small volatile molecules and physical structure changes during processing and storage of Chinese bacon, so that playing an important role in the flavor. But the oxidation process and the action mechanism are not clear. In this paper, we review the mechanism, impact on meat quality and control of protein oxidation as well as the current situation of research on protein oxidation in Chinese bacon, with the aim of prov...
