In modern dairy technology, milk is almost always subjected to a heat treatment; typical examples are: Thermization e.g.65°℃×15s Pasteurization LTLT (low temperature, long time) 63C 30 min HTST(high temperature, short time) 15s Forewarming(for sterilization)

The salts of milk are mainly the phosphates, citrates, chlorides, sulphates, carbonates and bicarbonates of sodium, potassium, calcium and mag- nesium. Approximately 20 other elements are found in milk in trace amounts, including copper, iron, silicon, zinc and iodine. Strictly speaking

Normal bovine milk contains about 3. 5% protein. The conce changes significantly during lactation, especially during the first ft post-partum(Figure 4. 1); the greatest change occurs in the whey fraction(Figure 4.2). The natural function of milk proteins is to supply

The stability, or instability, of the milk fat emulsion is very significant with respect to many physical and chemical characteristics of milk and dairy products. The stability of the emulsion depends strongly on the integrity of
