酶的分类 1961年国际生化协会酶命名委员会根据酶所催化的反 应类型将酶分为六大类，即氧化还原酶类、转移酶类、水 解酶类、裂解酶类、异构酶类和合成酶类，分别用1、2、 3、4、5、6的编号来表示，再根据底物中被作用的基团或 键的特点将每一大类分为若干个亚类，每个亚类可再分若 干个亚-亚类，仍用1、2、3、……编号。故每一个酶的分 类编号由用“．”隔开的四个数字组成

Like all other foods of plant or animal origin, milk contains several indigenous enzymes which are constituents of the milk as secreted. The principal constituents of milk (lactose, lipids and proteins) can be modified by exogenous enzymes, added to induce specific changes. Exogenous en- zymes may also be used to analyse for certain constituents in milk. In addition, milk and most dairy products

The water content of dairy products ranges from around 2.5 to 94%(w/w) (Table 7.1) and is the principal component by weight in most dairy products, including milk, cream, ice-cream, yogurt and most cheeses. The moisture content of foods (or more correctly their water activity, section 7.3), together with temperature and pH, are of great importance to food technology. As described in section 7.8 water plays an extremely important

Vitamins are organic chemicals required by the body in trace amounts but which cannot be synthesized by the body. The vitamins required for growth and maintenance of health differ between species; compounds regarded as vitamins for one species may be synthesized at adequate rates by other species. For example, only primates and the guinea-pig require ascorbic acid (vitamin C; section 6.4) from their diet; other species possess the enzyme gluconolactone oxidase which is necessary for the synthesis of vitamin C from D-glucose or D-galactose
