Fructooligosaccharides
Fructooligosaccharides, as a unique health food, have significant effects on improving gastrointestinal function, reducing blood lipids, regulating body balance, and enhancing immunity. Therefore, they are widely used in the food industry such as health food, beverages, dairy products, and candies, with a wide range of application prospects. The so-called oligosaccharides refer to the general term for sugars connected by glycosidic bonds of 2-10 monosaccharides. Fructooligosaccharides (FOS) are a very important class of oligosaccharides, which are excellent water-soluble dietary fibers and widely present in nature. Plants or fruits such as potatoes, onions, garlic, wheat, bananas, etc. have a higher content. 02
The physicochemical properties of oligofructose
2.1 Sweetness and Taste Quality: The sweetness of oligofructose with a purity of 50-60% is about 60% of the mass fraction of sucrose, while oligofructose with a purity of 95% is only 30% of the mass fraction of sucrose. Moreover, sucrose has a refreshing sweet taste, a pure taste, and no aftertaste. 2.2 Calorific value: The calorific value of oligofructose measured in vivo is only 1.5 kcal/g, which is extremely low in calories. 2.3 Viscosity: Within the range of 0-70 ℃, the viscosity of oligofructose is similar to that of isomers, but decreases with increasing temperature. 2.4 Water activity: The water activity of oligofructose is slightly higher than that of sucrose. 2.5 Moisturizing properties: The moisturizing properties of oligofructose are similar to those of sorbitol and maltose. 2.6 pH value thermal stability: When the environmental pH value is neutral, oligofructose is still very stable at 120 ℃, similar to sucrose; Under acidic conditions (pH=3), after reaching a temperature of 70 ℃, oligofructose is highly prone to partial grafting and its stability is significantly reduced. 2.7 Other processing characteristics: solubility, non coloring, shaping, alkali resistance, aging resistance, etc. High temperature resistance, inhibition of starch aging, water retention and stability are all good, but non hygroscopicity is poor.

The physiological functions of oligofructose
Due to the unique physicochemical properties of oligofructose, it has superior physiological functions. Through years of in-depth research by scholars and experts from various countries on oligofructose, as well as extensive experiments on animals and humans, it has been confirmed that oligofructose has significant effects on improving intestinal function, preventing and treating constipation and diarrhea, reducing blood lipids, and enhancing human immunity. 3.1 Regulating the balance of the body's microbiota and promoting the proliferation of bifidobacteria with high efficiency Fructooligosaccharides are internationally recognized as a popular super bifid factor. Experiments have shown that after consuming a certain amount of oligofructose, the beneficial bacterial group Bifidobacterium can proliferate 10-100 times in the human body. At the same time, the organic acids produced, such as acetic acid, lactic acid, propionic acid, butyric acid, etc., reduce the pH value in the intestine, inhibit the growth and reproduction of exogenous pathogenic bacteria and intrinsic spoilage bacteria in the intestine, reduce the growth and accumulation of spoilage substances in the intestine, improve the intestinal environment, promote intestinal peristalsis, and prevent constipation and diarrhea. 3.2 Lowering blood lipids and cholesterol Fructooligosaccharides are an excellent water-soluble dietary fiber. Through the action of intestinal bifidobacteria, FOS can ferment to produce propionic acid, hinder cholesterol synthesis, promote cholesterol to bile acid conversion, increase bile acid excretion, and effectively reduce the amount of serum cholesterol, triglycerides, and free fatty acids. It has a good improvement effect on a series of cardiovascular diseases such as hypertension and arteriosclerosis caused by high blood lipids. 3.3 Promoting the synthesis of vitamins and enhancing immunity Fructooligosaccharides can promote the natural formation of various vitamins and folate, produce a large amount of immune substances such as S-TGA immune proteins, effectively prevent bacteria from adhering to the host's intestinal mucosal tissue. A large amount of bifidobacteria can also strongly stimulate intestinal immune cells, increase the number of antibody cells, activate macrophage activity, and strengthen the human immune system. 3.4 Protecting the liver After absorbing oligofructose, Bifidobacterium rapidly proliferates and acts on spoilage bacteria such as Escherichia coli, Salmonella, and Clostridium, reducing the generation of toxic metabolites. At the same time, it quickly excretes toxic metabolites from the body, reducing the burden on the liver and protecting it. Moreover, the intake of oligofructose does not cause an increase in blood sugar and insulin levels. 3.5 Promoting the absorption of minerals and the elimination of toxic waste in the intestine Fructooligosaccharides have the function of combining dietary fiber with metal ions. In the acidic environment of the large intestine, the solubility of minerals such as calcium, magnesium, and zinc increases, and their bioavailability is also improved. Fructooligosaccharides can maintain the moisture of the intestinal wall, increase the moisture and acidity of the intestinal contents, and cultivate bifidobacterium intestinal wall to form a bacterial membrane protective barrier, thereby accelerating intestinal peristalsis and producing defecation reflex, which is conducive to the elimination of carcinogenic toxic waste such as indole and nitrosamines in the intestine. 3.6 Preventing Obesity Fructooligosaccharides, such as Fructosan and Fructotetrasaccharides, are not hydrolyzed by enzymes in human saliva and digestive enzymes in the small intestine, making them difficult to digest and absorb internally. Additionally, their calorific value is low. Therefore, consuming Fructooligosaccharides does not cause obesity.

The application of oligofructose
Based on the excellent physicochemical properties and physiological effects of oligofructose, it has been widely used in industries such as food, health products, and feed. 4.1 Application in ordinary food Fructooligosaccharides have low calorific value, good thermal stability, and have properties such as inhibiting starch aging. Therefore, they can partially replace sucrose and be added to baked foods such as cookies, bread, and mooncakes. Baked foods with added oligofructose have a pure sweet taste, good shape and color, and have the effect of promoting the proliferation of beneficial bacteria, which is both nutritious and healthy. In addition, oligofructose also has excellent solubility and shaping properties, which can be used in the production of candies such as chewing gum and peanut gummies. 4.2 Application in health products and special medical foods Based on the physiological effects of oligofructose mentioned above, it has been applied in various health products. In the domestic market, there are many health products that use oligofructose as raw materials or excipients, such as Baolingbao prebiotics, Jintongtong composite prebiotics, Aliguo prebiotics, Perfect brand oligofructose seabuckthorn tea, Shuchang oral liquid from Xiuyao Pharmaceutical, and Duoweisheng brand iron zinc calcium amino acid oligofructose oral liquid. According to data from the State Food and Drug Administration, there are 213 health foods mainly made from oligofructose, including 36 that improve gastrointestinal function, 75 that enhance immunity, and 5 that regulate blood lipids. 4.3 Application in Dairy and Beverages 4.3.1 Application in milk powder Fructooligosaccharides are more suitable for adding to infant formula and middle-aged and elderly formula production. Infants, young children, and middle-aged and elderly people have poor digestive function and are prone to calcium deficiency. Fructooligosaccharides not only have the proliferation effect of bifidobacteria, but also have the effects of lowering blood lipids, lowering blood sugar, and promoting the absorption of mineral elements. The appropriate amount of oligofructose in infant formula should be between 3% and 5%. At present, many enterprises such as Yili, Terracotta Warriors, Shengyuan, and Jinyang have added low fructose milk powder. 4.3.2 Application in Fermented Yogurt Adding oligofructose to fermented dairy products can serve as a nutritional source for live bacteria, enhance their activity, and extend their shelf life. Yogurt is one of the fastest-growing brands in dairy products, and in recent years, bifidous factor health yogurt with added oligosaccharides such as oligofructose has become popular. The amount of oligofructose added to yogurt is approximately 6%. 4.3.3 Application in Flavored Milk Beverages Adding oligofructose to flavored milk drinks can greatly enhance their nutritional and health benefits. The addition amount of oligofructose in flavored milk drinks is 6% -8%. Application of 4.3.4 in Lactic Acid Bacteria Beverages Active bacterial beverages contain a certain amount of beneficial bacteria, which will decrease significantly after digestion by the human body. The nutritional and health benefits of non active bacterial beverages are extremely limited. Adding oligofructose can improve the nutritional function of dairy beverages, and the amount of oligofructose added to lactobacillus beverages is about 6%. Fructooligosaccharides have various superior physiological functions and are a new type of sugar source that integrates nutrition, health care, and therapeutic effects. They have been widely used in the domestic and foreign dairy industry, such as being added to dairy products such as milk powder, yogurt, and pure milk. Domestic products with added oligofructose include: Oushichao Jinjiazhi infant formula milk powder produced by Mengniu Company, Jinzhuang multi-dimensional high calcium and high zinc milk powder for students, Yili Company's super Jinzhuang infant formula milk powder, Beiguan infant formula milk powder, Junlebao Dairy's Junlebao infant formula milk powder, etc.
