Fructooligosaccharides not only have the physical and chemical properties of general functional oligosaccharides, but also have the most remarkable physiological characteristics that they can obviously increase the proportion of microbial populations in the intestine. Fructooligosaccharides are the activation and proliferation factors of bifidobacteria in the intestine, which can reduce and inhibit the production of spoilage substances in the intestine, inhibit the growth of harmful bacteria and adjust the balance in the intestine. Can promote the absorption and utilization of trace elements iron and calcium, and prevent osteoporosis; It can reduce liver toxin, produce anticancer organic acids in intestine, and has obvious anticancer effect; And the taste is pure, sweet and delicious, with a fat-like fragrance and a refreshing and greasy feeling. In recent years, fructooligosaccharides are popular in Japan, Europe, the United States and other health care products markets.
The syrup is colorless or yellowish transparent viscous liquid, with the fragrance of fructooligosaccharides, soft and refreshing sweetness, no peculiar smell and no foreign impurities.
Sugar powder is white or yellowish amorphous powder (particles are white or yellowish amorphous particles), with soft and refreshing sweetness, fructooligosaccharide fragrance, no odor and no foreign impurities.
Six major effects
1. has a low calorific value, because fructooligosaccharides can not be directly digested and absorbed by human body, but can only be absorbed and utilized by intestinal bacteria, so its calorific value is low, which will not lead to obesity, and indirectly has the effect of losing weight. It is also a good sweetener for diabetics.
2. Because it can't be used by oral bacteria (referring to the mutant Streptococcus nigricans), it has the function of preventing dental caries.
3. Proliferation of intestinal beneficial bacteria. Fructooligosaccharides can selectively proliferate beneficial bacteria such as Bifidobacterium and Lactobacillus in the intestine, make beneficial bacteria dominant in the intestine, inhibit the growth of harmful bacteria and reduce the formation of toxic substances (such as endotoxin and ammonia). ), and protect intestinal mucosal cells and liver, thereby preventing the occurrence of pathological intestinal cancer and enhancing the body's immunity.
4. It can reduce the content of cholesterol and triglyceride in serum.
5. Promote the absorption of nutrients, especially calcium. Intake of fructooligosaccharides can improve the body's absorption of calcium ions, which has attracted more and more attention, and some human clinical experiments have been carried out one after another. For teenagers, inulin rich in fructooligosaccharides has been proved to have a positive effect on bone health, which can strengthen calcium absorption and increase bone density. For postmenopausal women, inulin rich in fructooligosaccharides has been proved to increase mineral absorption and improve bone health. Another clinical study shows that supplementing inulin rich in fructooligosaccharides can improve the mineral absorption of menopausal women and affect their bone renewal markers.
6. Prevention and treatment of diarrhea and constipation.

Main applications
1, fructooligosaccharide is not easily absorbed by human body, and its calorific value is very low, which will not lead to obesity, and can be used to produce diet food and low-calorie food; Fructooligosaccharides have low sweetness and can produce sugar-free or low-sugar foods, which are deeply loved by people.
2. Fructooligosaccharides have good physiological functions, and the produced functional health food can lower blood pressure, strengthen intestine and help digestion, and improve gastrointestinal function.
3. Fructooligosaccharides can obviously inhibit starch retrogradation, which is very prominent when used in food. Biscuits and baked goods produced with fructooligosaccharides are beautiful in color, soft and delicious, uniform in texture and good in preservation, which can greatly extend the shelf life.
4. Using the water-soluble dietary fiber characteristics of fructooligosaccharides, a new functional health wine can be developed, which is easy to digest and absorb, nourishes nutrition, enhances physical endurance, and is obviously beneficial to human health.
5. Fructooligosaccharides are still very stable at the low temperature of 25 ~ 5 degrees Celsius, and can be used in cold foods such as ice cream.
6. Fructooligosaccharides applied to milk powder are very effective in detoxifying and clearing intestines and regulating microecological balance in two directions.
7. Using fructooligosaccharides in lactic acid bacteria drinks can solve the problem of lactose tolerance, increase the content of water-soluble absorbable calcium, and make dairy products easier to digest and absorb.
8. Fructooligosaccharide is used as a prebiotic in animal feed production, which only kills harmful bacteria, not beneficial bacteria, and is safe and non-toxic to animals.
9. Adding fructooligosaccharides to cosmetics can inhibit the growth of harmful bacteria on the surface of facial skin, effectively slow down pigmentation, dilute and eliminate pigmentation, and have a good effect on skin health care.
L0。 Fructooligosaccharides can be used in combination with local specialty plants (such as Gynostemma pentaphyllum and aloe). ) R&D and production of internationally popular third-generation health care products.
1 1. Oligosaccharides have anti-tumor and immune functions: Many reports show that Bifidobacterium has anti-cancer effects. This may be due to the stimulation of immune system by Bifidobacterium cells, cell secretions and cell wall components.
Application of Fructooligosaccharides in Food
Fructooligosaccharide has been widely used in food, health care products and other industries at home and abroad because of its superior physiological function and physical and chemical characteristics, and is known as a new healthy sugar source integrating nutrition, health care and curative effect in 2 1 century.
(1) Application in dairy products The most extensive application of fructooligosaccharides in food is in dairy products. Adding fructooligosaccharides to fermented dairy products can provide nutritional sources for probiotics such as Bifidobacterium in products, enhance the quantity and function of live probiotics, and prolong the shelf life; Adding fructooligosaccharides to non-fermented dairy products (raw milk, milk powder, etc.). ) it can also solve the problem that middle-aged and elderly people and children are prone to get angry and constipation when supplementing nutrition. Fructooligosaccharides are more stable than sucrose under acidic conditions and can proliferate bifidobacteria, so they are widely used in acidic foods such as yogurt and lactic acid bacteria drinks to replace part of sucrose.
(2) Application in cereal food Adding fructooligosaccharides to cereal products can improve product quality and prolong product shelf life. For example, adding fructooligosaccharides to baked goods can improve the color and brittleness of the products, which is beneficial to puffing. If sucrose is used as the sugar source, the color of the product will become darker if it is not treated properly, and the coloring effect of fructooligosaccharides is better than that of sucrose. Maillard reaction of fructooligosaccharides endows baked food with good flavor and attractive color. In addition, adding proper amount of fructooligosaccharides to bread can produce moisturizing effect, delay starch aging, prevent food from hardening, make it soft and delicious, and extend the shelf life.
(3) Application of Fructooligosaccharide in Candy and Beverage As a unique functional sweetener with low sugar, low calorific value and indigestion, adding it to sweet food and beverage can improve the taste of the product and reduce the calorific value of the food. In fact, fructooligosaccharides can replace some sucrose to produce various sweets, such as candy, jelly, chocolate and so on. It can not only keep a certain sweetness, but also prevent dental caries, especially suitable for children. Adding fructooligosaccharides to fruit-flavored drinks and tea drinks can make the taste of products softer and fresher.
