FUNCTION
1. As an absorbent dispersant for powder food pigment, it can reduce the pigment concentration, facilitate the use and reduce the discoloration during storage.
2. Using the characteristics of easy compression forming and low water absorption, it is used as an excipient.
3. The caramelization temperature of lactose was low (sucrose 163ºC).Glucose 154.5ºC, lactose only 129.5ºC), for some special baked foods, at lower baking temperatures to obtain a deeper yellow to caramel color.
4. Other has prevents the crystallization, reduces the sweetness,
APPLICATION
Lactose widely used in making baby food, candy, margarine, etc., it can also be used as medium, chromatogram absorbent and excipient, etc
Lactose is commonly used in baby food. It is also widely used in beverages, western sausages, sauces, instant foods, spice blends and meat products in the food industry to supplement low sweetness, enhance aroma, prolong sales period and increase product value.
Lactose other derivatives, such as heteroemulsified sugars, can also be made for the processing of different foods and are often used as tablets.
