What Is Stachyose?
What is stachyose?
Stachyose is a saccharide formed by combining two α-galactoses with 1,6-glycosidic bonds on the glucose side of sucrose. The molecular formula is C24H42O21. 22%, refreshing taste and no peculiar smell. Soluble in water, insoluble in ether, ethanol and other organic solvents.
Stachyose has good thermal stability and will not decompose at a high temperature of 100°C, but its thermal stability decreases under acid conditions, so it can be used in foods that require autoclaving. The storage stability in an acidic environment is related to temperature, and it is quite stable when the temperature is lower than 20 °C. The moisture retention and hygroscopicity are lower than that of sucrose but higher than that of high fructose syrup, and the osmotic pressure is close to that of sucrose. Above 80°C, stachyose has coloring properties and can be added to baked goods to give the food an attractive burnt yellow color

Natural sources of stachyose: Stachyose is a substance that exists in nature, and it is contained in the vegetables we often eat and Chinese medicinal materials for treating diseases. Cordyceps ginseng has the highest content and has the longest history of consumption.
Benefit:
1.Regulating the balance of intestinal flora
Stachyose can improve gastrointestinal function through its dual functions (as soluble dietary fiber and bifidobacterium proliferation), and can effectively improve symptoms such as constipation, diarrhea and colitis.
2. Promoting the absorbtion of mineral element and metabolism of lead
Thunb has an excellent laxative effect, which can greatly reduce the retention time of food residue in the intestine and reduce the chance of lead being absorbed in the intestine.
3. Relieving constipation
Bifidobacterium fermentum produces a large amount of short-chain fatty acids, which can stimulate intestinal peristalsis and increase fecal moisture.
4. Regulating immune function
It has the structure of Gal- -1, 6-gal. Studies abroad have confirmed that this kind of -Gal structure is involved in biological processes such as immunity, adsorption between pathogens and cells on the basis of the molecular mechanism of group receptor sympathetic response, so that it has the functions of preventing pathogen infection, neutralizing toxins and regulating the immune system.
Application areas:
1. It can be added to liquid food, such as lactic acid beverage, vinegar beverage, beer and other beverages, to develop new functional food, and the addition amount is small, the effect is remarkable, and the flavor of the original food will not be damaged.
2. It has active factors, which can adsorb toxic substances and pathogenic bacteria in the gastrointestinal tract, improve the body's disease resistance and enhance immunity, so it can be widely used in medicine.
3. When added to baked goods, it can keep moisture and change the rheological properties of dough.
4. Stachyose is not hydrolyzed by digestive enzymes, and its metabolism is independent of insulin, which can meet the needs of special populations such as diabetes, obesity and hyperlipidemia.
5. Stachyose can promote the absorption of calcium and magnesium by the human body, and can be used as an ideal raw material for the development of food for pregnant women and the elderly.
