| Product Name | Anhydrous Lactose |
| CAS | 63-42-3 |
| Molecular Formula | C12H22O11 |
| Appearance | White crystalline powder |
Anhydrous Lactose is a naturally occurring simple carbohydrate, or sugar, found only in the milk of mammals. For this reason, it is also commonly referred to as "milk sugar." All commercial lactose is obtained from the milk of cows as a by-product of the dairy industry. Chemically, lactose is the disaccharide of the simple sugars D-galactose and D-glucose (Figure 1). In other words, the lactose molecule comprises one molecule of D-galactose chemically linked to one molecule of D-glucose. Lactose exists in two isomeric forms, known as alpha and beta (designated a-lactose and b-lactose).
Mainly used for: as the powdery food pigment adsorption dispersant, reduce the pigment concentration, easy to use and reduce discoloration during storage. Advantage of the characteristics of easy compression forming and low water imbibition, a tablet excipients, etc. Use lactose caramelization low temperature (163 ºC. The hydrolysis of sucrose into glucose 154.5 ºC, lactose is only 129.5 ºC), the characteristics of for some special baked goods, can be obtained under low baking temperature deep yellow to caramel color. Other have prevent crystallization, to reduce the sweetness, prevent caking and enhance aroma, and so on. Used for baby food, sweets and margarine, etc.
