Milk is a dilute emulsion consisting of an oil/fat dispersed phase and an aqueous colloidal continuous phase. The physical properties of milk are similar to those of water but are modified by the presence of various solutes (proteins, lactose and salts) in the continuous phase and by the degree of dispersion of the emulsified and colloidal components

Cheese is a very varied group of dairy products, produced mainly in Europe, North and South America, Australia and New Zealand and to a lesser extent in North Africa and the Middle East, where it originated during the Agricultural Revolution, 6000-8000 years ago. Cheese production and con- 10A and 10B), is increasing in traditional

核酸存在于每一个活细胞中，是遗传信息的携带者和传递者。核酸由核苷酸所组成，核苷酸的组成物质为嘌呤、嘧啶、核酸及核糖(或脱氧核糖)

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

脂肪酸是高等动、植物的重要能源。脂肪在动物脂肪组织、细胞中可大量储存。植物的种子和果实中 常储有大量脂肪。脂肪酸对正常膳食的人约提供所需全部能量的 40％。对于饥饿或冬眠动物以及候鸟迁移 时，脂肪酸则更是主要的能量来源

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
