Appearance properties white crystalline or crystalline powder. It is sweet, about 70% as sweet as sucrose. Odorless or slightly characteristic odor. Relative density d4201.525(water content). It has reducibility and dextrotropism. There are α-type and β-type isomers. Alpha-lactose can be broken down into glucose and galactose by acids and lactase enzymes. It can be converted into lactic acid by lactic acid bacteria, but cannot be utilized by yeast.

In the water crystallization precipitation, is C12 H22O11.H2O monohydrate, such as heating at 120℃, can become anhydrous substance. Anhydrous melting point 201 ~ 202℃, 1g soluble in 5ml water or 2.6ml hot water, slightly soluble in ethanol, insoluble in ether.
β-lactose precipitates in hot water above 93℃, and its solubility is different from that of α-lactose. 1g is dissolved in 2.2ml water or 1.1ml hot water. Melting point 252℃, rotation [α]D20+53.6°. It can be hydrolyzed to glucose and galactose in 2% sulfuric acid emulsion.
Only exists in animal milk, human milk contains about 7%(5%-8%), cow milk contains about 4.5%(4%-5%). At body temperature, the mixture is balanced by a ratio of two alpha-types to three β-types. The common lactose commodity is α-type.
