Galacto-oligosaccharide
Galacto-oligosaccharide (Galactooligosaccharides, GOS) is a kind of natural property of functional oligosaccharides, and its molecular structure is typically galactose, or glucose molecules connected to the 1 ~ 7 Gal, the Gal-(Gal) n-Glc/Gal (n **6).In nature, animals, the re are trace amounts of milk GOS, and were more content in breast milk, infant Bifidobacterium flora in the body to establish a large extent dependent on the GOS ingredient in breast milk.
Galacto-oligosaccharide is the only 8 can be a great human intestinal bacteria for their use.
Galacto-oligosaccharide prospects
Galacto-oligosaccharide as a new functional food in China will have broad market prospects.This is the China Fermentation Industry Association, China Association of Production and Application of Food Additives and Cote (China) Co., Ltd., Japan, co-sponsored the "galacto-oligosaccharide Conference" was informed.Currently, oligosaccharides, or a new industry in China, can reach thousands of tons production scale, only Isomaltooligosaccharide wheat sugar and oligofructose, galacto-oligosaccharide has yet to scale.
It is reported that Japan is the world's most developed country in oligosaccharides, including galacto-oligosaccharide production ranks second in the world.In recent years, the structure of the Japanese diet has undergone major changes, the traditional rice gradually being replaced by beef and dairy.With that, all kinds of "modern" diseases such as diabetes, high blood pressure patients gradually increased.In addition, Japan has entered the aging society, the elderly focus on physical health.Therefore, the community requires the development of functional foods increasingly strong voice.The Government of Japan has become more importance to this work, the early *0s from the food division of the health food, and calls upon all universities, research institutes and other research and development units.China is similar to the situation with Japan, the traditional "eat" the structure is slowly changing, meat, dairy class consumption gradually increase in the relative reduction of grain foods.And the social phenomenon of aging have begun to appear.Hypertension, diabetes, various oral and digestive system diseases gradually increased.Community development functional food, health food requirements are increasing.

Galacto-oligosaccharide has a strong acid resistance, heat resistance, not because of the high-temperature sterilization process and human gastric acid by the decomposition of the characteristics of its original due, and fructose not have these features.Galacto-oligosaccharide can be lactic acid bacteria and bifidobacteria rod rod A B bacteria while taking advantage of.FOS FOS and other oligosaccharides may only be used lactic acid bacteria A rod, bar B strains of bifidobacteria was not significant
