Lactose Raw Materials Powder Lactose
Product Overview:
Lactose is a disaccharide naturally found in mammalian milk. It is secreted by the mammary glands of mammals and exists only in the animal kingdom. The molecular formula is C12H22O11. It is a disaccharide composed of glucose and galactose, which is formed by the dehydration of the hydroxyl group on the fourth carbon atom of glucose and the β-hemiacetal hydroxyl group on the first carbon atom of galactose to form a glycosidic bond.

Lactose Raw Materials Powder Lactose Details
Lactose Powder Usage and Synthesis.
Lactulose is made by converting lactose as raw material through alkali. The isomerization reaction is carried out by heating in sodium hydroxide solution, and borates are used to facilitate the isomerization reaction.
Under alkaline conditions, the glucose residues in the lactose molecule undergo isomerization reaction and are converted into fructose residues, which are then produced through ion exchange, decolorization, concentration and crystallization.
Due to the large consumption of alkali, lactulose is expensive and was previously used as a medicine. At present, the sugar has been produced by Morinaga Milk Industry in Japan and is mainly added to products such as cow's milk and milk powder. Lactulose that appears in heated dairy products is the product of isomerization of endogenous lactose.
In addition, enzymatic isomerization can also be used to produce lactulose; or 1:1 sucrose and lactose are used as raw materials and enzymatic conversion is used to produce lactulose.
Uses and functions of Lactose.
Nutritional sweetener; excipient; dispersant; flavoring agent; nutrient.
Mainly used as an adsorbent dispersant for powdered food pigments to reduce pigment concentration, facilitate use and reduce discoloration during storage. Taking advantage of its easy compression and low water absorption, it is used as an excipient for tableting. Taking advantage of the low caramelization temperature of lactose (sucrose 163℃.
Glucose 154.5℃, lactose only 129.5℃), for some special baked foods, a darker yellow to caramel color can be obtained at a lower baking temperature. Others
It has the functions of preventing crystallization, reducing sweetness, preventing adhesion and enhancing flavor. It is used in baby food, candy and margarine, etc.
Pharmacological effects of Lactose.
Product method of Bulk Lactose Powder.
It is obtained by heating or adding lime milk to whey (containing about 5% lactose) in milk, removing protein, concentrating, cooling, crystallizing and drying. The yield is about 60% to 70%.
