Product Description

What Are Lactose Powder ?

Pure Lactose powder is a disaccharide naturally present in mammalian milk. Secreted by the mammary glands of mammals, it only exists in the animal kingdom. Molecular formula C12H22O11. It is a disaccharide composed of glucose and galactose, which is obtained by dehydrating the hydroxyl group on the fourth carbon atom of glucose and the β-hemiacetal hydroxyl group of the first carbon atom in galactose to form a glycosidic bond. Therefore, the reducing property of the aldehyde group contained on the glucose molecule is still maintained. There are α-type and β-type isomers. The α-lactose that crystallizes from the mother liquor below 93.5°C contains a molecule of crystal water, with a melting point of 202°C, a specific rotation of +88°, and a solubility of 7.4 grams. The β-lactose that crystallizes above 93.5°C has a melting point of 252°C, a specific rotation of +34°, a solubility of 55 grams, and no crystal water in the molecule. The hygroscopicity of α-type sugar is low, and it does not absorb external moisture in a high humidity environment, which is extremely important for controlling the activity of water in food.
In dehydrated milk and whey products, lactose often exists as amorphous crystals, has strong hygroscopicity, a solubility of 20 grams (at room temperature), and a sweetness of only 30% of sucrose. It is not suitable as a sweetener. It can only be used when the food is sweet or has a special flavor. The content of lactose in liquid whey is about 6.5%. After deesterification and clarification, it is concentrated at 55-60°C to make it solid, and the content can be increased to 55-65%. After cooling treatment, a large number of crystals can be obtained. Remove the mother liquor and wash the crystals to obtain slightly yellow edible lactose with a purity of 99.6%. If recrystallization is carried out, high-purity medical lactose can be obtained. Human milk and cow's milk contain 5-7% and 4% lactose, respectively. Lactose is often used in baby food, and it is also widely used in beverages, western-style sausages, sauces, instant foods, spice mixtures and meat products in the food industry to supplement low sweetness, enhance aroma, prolong sales period and increase product value. It can also be made into other derivatives (such as heteroemulsifying sugar) for processing different foods, and is also commonly used as a tablet preparation for tablets.

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.

What Are The Benefits?

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.

What Are The Application Directions?

Used to make baby food, candy, margarine, etc. It is used as a flavoring agent in medicine and can be extracted from whey.
α-Lactose hydrate is widely used in the production of pharmaceuticals, as fillers, glidants, disintegrants, lubricants and binders in solid preparations, and as excipients in lyophilized preparations. Lactose is recorded in the pharmacopoeias of many countries

Nutritive sweetener; excipient; dispersant; flavoring agent; nutritional agent. Mainly used:
As an adsorption and dispersing agent for powdered food coloring, it reduces the concentration of the coloring material, which is convenient to use and reduces discoloration during storage.
Utilizing the characteristics of easy compression molding and low water absorption, it can be used as excipients such as tablet compression.
Taking advantage of the low caramelization temperature of lactose (sucrose 163°C, glucose 154.5°C, lactose only 129.5°C), for some special baked foods, a deeper yellow to caramel color can be obtained at a lower baking temperature .
Others have the functions of preventing crystallization, reducing sweetness, preventing sticking and enhancing flavor.
Used in baby food, candy and margarine etc.
