Pure lactose powder is a reducing disaccharide naturally found in mammalian milk. It appears as a white to off-white crystalline powder or granules, with a slightly sweet taste (approximately 30% as sweet as sucrose). It is readily soluble in water but slightly soluble in ethanol. In infant formula, lactose is the main carbohydrate in breast milk, used to mimic its sugar composition. In pharmaceuticals, lactose is a preferred excipient as a filler and diluent due to its good flowability and compressibility. In the food industry, lactose serves as a low-sweetness carrier and flavor enhancer in Western-style sausages, sauces, instant soup mixes, and spice premixes, improving color and extending shelf life. Furthermore, lactose can be further derived into functional components such as lactitol and lactobionic acid.

YTBIO supplies pure lactose powder with a purity of over 99%, customizable particle size, suitable for various applications including infant formula, solid beverages, compressed candies, and veterinary excipients. Small-sample testing and flexible MOQ are supported.

Product Details 

Solubility

The solubility of lactose is lower than that of sucrose, and the solubility of α-type and β-type lactose is also different. After putting lactose into water, part of the lactose dissolves in water, and the solubility when it reaches saturation is the solubility of α-lactose in water, also known as the initial solubility. The initial solubility of lactose is low and is less affected by water temperature. When the above saturated solution is shaken or stirred, lactose can still be dissolved, and finally reaches the saturation point, which is the final solubility of lactose. So the ultimate solubility of lactose refers to the equilibrium solubility of α-lactose and β-lactose at a certain temperature. The solubility of lactose increases with the increase of temperature and is greatly affected by temperature.

Pure Lactose powder is a source of energy for the human body just like other sugars. 1/4 of the total calories in milk comes from lactose.
In addition to providing energy for the human body, lactose also has a different physiological meaning from other sugars. Lactose is not digested and absorbed in the human stomach, and can go directly to the intestinal tract. In the human intestine, lactose is easily decomposed into glucose and galactose by lactase for absorption. Galactose is a component of glycolipids that constitute the brain and nervous tissue, and is very important to the intellectual development of infants. It can promote the production of galactocerebrosides and mucopolysaccharides. Lactose can promote the production of certain lactic acid bacteria in the human intestine, inhibit the growth of spoilage bacteria, and help the peristalsis of the intestine. Since the production of lactic acid is beneficial to the absorption of calcium and other substances, and can prevent the occurrence of rickets, lactose is often fortified in baby food.

heat supply
The main function of lactose is to provide heat energy for the human body. Children and adults need a lot of heat energy for growth and development, metabolism, tissue synthesis, maintenance of normal body temperature, physical exercise, and labor.

Adjust and protect the stomach
The development of human brain cells and the soundness of the entire nervous system require a large amount of lactose. Another important function of lactose is to promote the growth of lactic acid bacteria in the intestine. Lactic acid is produced under the action of lactic acid, which can regulate and protect the intestines and stomach. It can inhibit the poisoning caused by toxins produced by abnormal fermentation in the intestines, and can also inhibit the reproduction of harmful bacteria in the intestines.

Promote calcium absorption
Another function of lactose is to promote the body's absorption of calcium in the process of calcium metabolism. The sweetness in milk comes from lactose, but lactose is less sweet than other sugars. Lactose forms organic acid after the action of lactase in the intestinal tract, which reduces the pH value of the intestinal tract. Under the action of acid, it can promote the absorption of calcium, iron, zinc and other nutrients. In addition, a portion of glucose formed after the decomposition of lactose also promotes calcium absorption.

promote growth and development
At the same time, lactose can also maintain the water balance in children, provide galactose related to the composition of the brain and vital organs, and is also necessary for the storage of starch. Galactose is particularly important for children's brain development, it can promote the production of cerebrosides and mucopolysaccharides.

Improve constipation

After the incompletely decomposed lactose enters the large intestine, the intestinal flora, especially lactic acid bacteria and Bifidobacteria, will ferment the lactose to produce lactic acid and other substances. Lactic acid irritates the intestinal wall, increasing bowel movements. Therefore, to a certain extent, it has the effect of adjusting the intestinal tract and preventing the baby from being constipated and getting angry.

Provides energy, aids neurodevelopment

Lactose is a disaccharide that is broken down in the body into a portion of glucose and a portion of galactose, which are then utilized by the body. Among them, glucose can provide heat for the body, which is very important for infant growth and development, metabolism, tissue synthesis, etc.; galactose is the main energy to promote the development of the baby's brain and nervous system.

The taste is good, the baby likes it more

The taste is slightly sweet, and it can also make the milk flavor of formula milk powder more mellow. Other sugars such as sucrose (white granulated sugar), corn syrup, and maltodextrin are sweeter, which can easily cause adverse symptoms such as sweetness, partial eclipse, obesity, and dental caries in infants and young children.

Digestion and absorption

Lactose is the only disaccharide present in milk in the form of a monomer molecule, which is formed by the linkage of glucose and galactose through 1,4-glycosidic bonds, and is produced by the action of lactose synthase in the mammary gland. The most abundant content in human milk is about 7.2g/l00mL. Lactose is mainly digested and absorbed in the jejunum and ileum, where it is hydrolyzed into glucose and galactose by lactase secreted by the brush border of the epithelial cells of the small intestine, and then absorbed through the active transport of cells. Glucose mainly provides energy for the body, while galactose is bound to ceramide by glycosidic bonds to form galactocerebroside, which participates in the development of the brain. Infancy is a critical period for neurodevelopment, therefore, lactose is essential for the development of the nervous system in infancy.

I. Food Industry

Dairy Products and Infant Foods
As a natural carbohydrate in milk (approximately 4.5%-5.0%), lactose is a key ingredient in infant formula, used to mimic the sugar content of breast milk, aiding in calcium absorption and the growth of beneficial gut bacteria. In fermented dairy products such as yogurt and cheese, lactose provides a fermentation substrate for lactic acid bacteria and participates in flavor and texture formation.

Baking and Confectionery
Lactose has a low caramelization temperature (approximately 129.5℃), allowing it to form an ideal golden color in baked goods such as bread and biscuits at lower temperatures. In confectionery, lactose inhibits sucrose crystallization, maintaining a smooth and delicate texture.

Other Foods
In sports drinks, lactose is hydrolyzed into glucose and galactose, providing sustained energy as a slow-release carbohydrate. Adding small amounts to condiments such as soy sauce and salad dressing can adjust flavor.

II. Pharmaceuticals

Due to its stable chemical properties and good compressibility, lactose is an important excipient in the pharmaceutical field. It is widely used as a filler in solid dosage forms such as tablets and capsules, increasing the volume and weight of the tablets. Simultaneously, lactose improves the flowability of drug powders, helping tablets disintegrate rapidly in the body, promoting drug release and absorption. Its slightly sweet taste also makes it a common flavoring agent.

III. Other Applications

Daily Chemical Industry: Used in daily necessities such as facial cleansers, face creams, shampoos, and toothpaste.

Feed Industry: Used as a nutritional additive in pet food, animal feed, and aquatic feed.

Health Supplement Industry: Used as a raw material for prebiotics to promote gut health.
