Galactinum - How to solve lactose intolerance
Author:
Abstract:
How to solve the problem of lactose intolerance high sub-level (Beijing aonite Dairy Trade Co., Ltd.) milk is an important dietary resource, containing a variety of essential nutrients for human health, at the same time, milk is the main food for newborn babies. The carbohydrate in milk is lactose, which is a disaccharide composed of galactose and glucose through β1,4 glycosidic bonds. Its content in milk is about 4.8...

Abstract:
lactose is a specific carbohydrate in milk and is the main source of energy in foods for infants and young children. Digestion and absorption of lactose play an important role in the normal growth and development of human beings. When the body is lack of lactase, lactose in milk can not be digested and absorbed in the small intestine, but directly into the large intestine, under the action of coliform flora, causing fermentation, hydrolysis and a series of symptoms such as abdominal distension, bowel sound, gas, or Diarrhea, etc., is called lactose intolerance. Lactose deficiency has been reported to be related to race, genetics, and geographical environment, and thus children in different countries have different ages at which lactose activity decreases or disappears. With the increasing awareness of the important role of dairy products in human nutrition and the gradual improvement of intake, the absorption and utilization of lactose will become an important research topic in the field of nutrition. The age at which lactase activity decreased or disappeared, lactose malabsorption, the incidence of lactose intolerance and the relationship with the incidence of milk intolerance in Chinese children were studied.

Galactinum - Introduction
Lactose is a disaccharide consisting of glucose and half Lactose. Here are some information about the nature, use, formulation and safety of Lactose:
Nature:
-Appearance: White crystalline powder
-Statement: Lactose is a sweet substance, but compared to glucose, its sweetness is weak
-Solubility: The solubility of Lactose in water is low, and the solubility increases with the increase of temperature
-Stability: Lactose is relatively stable in high temperature, acidic and alkaline environments
Use:
-Food industry: Lactose is a common food additive used in the manufacture of dairy products such as milk powder, dairy beverages, ice cream, chocolate, etc. It can increase the sweetness and taste of food, and is also used to increase the moisture retention and stability of food.
-Pharmaceutical industry: Lactose is often used as excipients and additives in the pharmaceutical process for the manufacture of tablets, granules, capsules, etc. It can function as a diluent, hygroscopic agent and rheological agent.
Preparation Method:
- Lactose is mainly obtained by Lactose separation and extraction process. The main methods are acid hydrolysis and enzymatic hydrolysis. Acidolysis uses an acid to hydrolyze Lactose, producing glucose and half Lactose. The enzymatic law uses Lactose enzymes to catalyze the hydrolysis of Lactose molecules.
Safety Information:
- Lactose is generally considered safe for most people, but a minority may be allergic or intolerant to Lactose. Lactose intolerance refers to a gastrointestinal reaction caused by the inability to completely digest Lactose in the body due to the lack of Lactose enzyme.
- Lactose can be absorbed and metabolized by the body, but excessive consumption of Lactose for a long time may cause symptoms such as indigestion and diarrhea.
-If you are allergic to Lactose or have a Lactose intolerance, you should avoid foods or medicines that contain Lactose.
