The lactose is named for being the disaccharide in mammal milk. Its molecular structure is condensed by single molecule glucose and single molecule galactose. It is sweet in taste and takes about 4% in cow's milk and 5% to 7% in human milk. In industrial manufacture, it is extracted from whey and used to make infant food, candy and man-made milk, etc. It is usually used as flavoring agent medically. The lactose is 4-O-β -D-pyran galactosyl-D-glucose-monohydrate.
As one of the most important nutrient substances for children's growth and development, lactose is significant for the mental development of youngsters, and especially indispensable for newly born infants. In nature, lactose only exists in mammal milk and can't be found in vegetalitas foods.Lactose is peculiar to mammals, milk sugar, hence the name. Also is a kind of disaccharides, as a member a molecule of glucose and galactose condensation, larger molecules. The average content of 4.6 to 4.7% in the milk lactose after lactose digestion form glucose and galactose, provide nutrition for human beings, to provide energy.
Lactose is galactose beta 1, 4 glycosidic bond with glucose reducing disaccharide, called pyran 4 - o - beta - d galactose - d - pyran glucose, reduction based on glucose units.There are two kinds of isomers, lactose alpha and beta lactose lactose.
The role of lactose:
1. The fermented milk is necessary, provide the carbon source.Under the action of lactic acid bacteria, lactose into galactose and glucose.
2. Provide nutrition, provide energy for mankind.Galactose have important effects on mammalian neural development.Lactose is conducive to the absorption of calcium.Lack of lactase can lead to lactose intolerance.
3. The dairy products has an important influence on the organization.Condensed milk, lactose crystallization effect on the condensed milk taste.The solubility of the milk powder.
4. Has important effect on dairy products color, flavor.Browning reaction.After fermentation flavor formation.
Lactose is to promote the role of calcium absorption:
In the intestinal tract is not easy to break down lactose, can be in intestinal stranded for a long time.Through the enzyme lactase lactose forms after organic acid, can reduce the intestinal PH, under the action of acid, can promote the absorption of calcium ions.In addition, there are also lactose forms after the decomposition of glucose to promote calcium absorption.
Lactose is the intestinal function:
Enzymes in the small intestine is not lactose lactose will be moved to the large intestine, microbial life in the large intestine may use lactose, which is the lactic acid bacteria, the bacteria most compared with German bacteria will lactose into lactic acid, acetic acid, decrease intestinal PH value, these organic acid can stimulate the intestinal peristalsis, so have the whole bowel function, can prevent the baby constipation.
What is lactose to add the in milk powder of function ?
1. Some baby due to premature low lactose can cause intestinal enzyme activity, so that they can't normal nursing, and by the lactose down into galactose can promote the brain and the generation of mucopolysaccharide, thereby promoting the infant baby's mental development;In addition, the lack of lactase that babies causes symptoms such as diarrhea, abdominal pain, which leads to the infant baby sickly, affect growth, resistance to diseases and immunity also fell.
World famous nutrition experts AKobayashi waiting for eight months baby as the object, the lactose in food and lactose enzymes was studied in normal infants of intestinal absorption of calcium and magnesium, it is found that, in the baby drink milk lactose, reduced intestinal absorption of two elements, drink contains lactose enzymes dairy infant will rise.Calcium and magnesium absorption is bad, will cause the baby prone to allergic reactions.Aiming at this situation, can not develop new baby infant milk powder, make the quality of the baby milk powder in China has a big enhancement.
2. Lactose's main function is to supply the body with heat, adults and children's growth, metabolism, synthesis of the organization, to maintain normal body temperature and physical exercise, labor work requires a lot of heat energy, especially the children to digest sugar decomposition using than adults, lactose is children body organs, nerves, limbs, muscle development and activities such as power.
Another important role is to promote pediatric the reproductive growth of lactic acid bacteria in the gut, lactose in intestinal lactobacillus and streptococcus, a variety of enzymes and some microbes generated under the action of lactic acid, lactic acid is adjusted for pediatric gastrointestinal protection, it can inhibit intestinal toxins poisoning caused by the situation of the abnormal fermentation, also can inhibit intestinal harmful bacteria breeding.
Another function of lactose is in the process of calcium metabolism can not promote children's absorption of calcium.Sweetness is derived from lactose in the milk, but some low lactose and other sugars than sweetness so will not result in a pediatric partial eclipse.
Lactose also can keep moisture balance in children, provide related to brain and vital organs of galactose, and storage of starch is also necessary.Galactose is especially important for children's brain development, it can promote the brain glycosides lipid and mucopolysaccharide.If lack of lactose can cause children's weight, fatigue, weight loss, growth and development is slow, and even children to consume the body fat, protein, this protein deficiency may occur.
Lactose main functions:
Lactose main function body heat supply children's development, metabolism, organize and maintain body temperature and heat special requirement for physical exercise, fatigue work sugar solution lactose digestion and absorption utilization are better than strong internal organs, nerves, limbs, muscle development and force, etc Another important role to promote intestinal lactobacillus breeding increased intestinal lactobacillus and streptococcus lactose, enzymes and some small things lactic acid lactate gastrointestinal protection can inhibit intestinal different fermentation to produce toxins build poison phenomenon inhibit intestinal bacteria breeding Another role calcium metabolism process for calcium absorption milk lactose sweetness comes from low lactose lactose than its sugar sweetness made partial eclipse With lactose can keep balance of body water with vital organs compose closed galactose and starch storage necessary galactose is especially important to children's brain development can promote cerebral fat class without sticky sugar lactose causes children's weight, fatigue, weight loss, slow development, and even child can consume the body fat, protein protein deficiency.
