Lesson 3 Amino acids
Para.1 Amino acids are produced using a range of technologies including direct fermentation, biotransformation of precursors using cells or enzymes, extraction of protein hydrolysates and chemical synthesis. They have a variety of uses as nutrients and flavours in the food and feed industries.
1. a range of fruit-flavoured toppings (蛋糕上的各种果味配料) 2. Control of a range of food related microorganisms by a multi-
parameter preservation system (利用多参数保藏系统控制一系列食品相关微生物)
译文 氨基酸的生产有很多种方法,包括直接发酵法、利用
细胞或酶对前体进行转化、蛋白质水解物提取法和化学合 成法。在食品和饲料工业中,氨基酸具有诸如作为营养素 和调味剂的多种用途。

Lesson 3 Amino acids
Para.2 While fermentation or biotransformation processes have been developed for production of all amino acids except glycine, L-cysteine and L-cystine, not all of these processes are commercially viable. Lasparagine, L-leucine, L-tyrosine, L-cysteine, and Lcystine are produced by purification of protein hydrolysates.
