Fructooligosaccharide powder

What is fructooligosaccharide powder?

Fructooligosaccharides are also known as fructooligosaccharides or sucrose trisaccharide oligosaccharides. It uses sucrose as raw material and is converted and refined by modern bioengineering technology-fructosyltransferase. Naturally occurring and enzymatically produced fructooligosaccharides are almost always in linear form. As a non-reducing sugar, fructooligosaccharides are similar to sucrose in terms of viscosity, water activity, wettability, thermal stability under acidic conditions, and processing properties.

Fructooligosaccharides Powder have the dual qualities of exact health care functions and excellent food ingredients. It has excellent physiological functions such as low caloric value, no dental caries, promoting the proliferation of bifidobacteria, lowering blood sugar, improving blood lipids, and promoting the absorption of trace elements. In recent years, among many oligosaccharide foods, fructo-oligosaccharide powder has been recognized by international nutritionists as a "water-soluble dietary fiber with excellent indigestibility". It can regulate the microecological balance of human body in both directions and is a typical super bifid factor. It is favored by modern food production enterprises and consumers. Widely used in third generation health food.

Physicochemical properties of fructooligosaccharides

1. Sweetness and taste: The sweetness of fructooligosaccharides with a purity of 50-60% is about 60% of the mass fraction of sucrose, and the sweetness of fructooligosaccharides with a purity of 95% is only 30% of the mass fraction of sucrose, and the sweetness of sucrose is The taste is refreshing and pure without any aftertaste.

2. Caloric value: The caloric value of fructooligosaccharide measured in the body is only 1.5kcal/g, which is extremely low.

3. Viscosity: In the range of 0-70°C, the viscosity of fructooligosaccharides is similar to that of isomeric sugars, but it decreases as the temperature rises.

4. Water activity: The water activity of fructooligosaccharides is slightly higher than that of sucrose.

5. Moisturizing properties: The moisturizing properties of fructooligosaccharides are similar to those of sorbitol and maltose.

6. PH thermal stability: When the environmental pH value is neutral, fructooligosaccharides are very stable at 120°C, similar to sucrose; under acidic conditions (PH=3), after the temperature reaches 70°C, fructooligosaccharides are extremely stable. It is easy to connect to the branch office and the stability is obviously reduced.

7. Other processing characteristics: superior solubility, non-coloring, formability, alkali resistance, aging resistance, etc. It has good high temperature resistance, inhibition of starch aging, water retention and stability, but poor non-hygroscopicity.

What are the effects of fructooligosaccharides?

1. Regulate the balance of flora in the body and efficient bifidobacteria proliferation factor

Fructooligosaccharides are internationally recognized as a popular super-powerful bifidus factor. Experiments have shown that after the human body consumes a certain amount of fructo-oligosaccharide, the number of beneficial bacteria in the human body, Bifidobacterium, can multiply 10-100 times. At the same time, the organic acids produced such as acetic acid, lactic acid, propionic acid, butyric acid, etc. will increase the intestinal pH value. Reduce and inhibit the growth and reproduction of exogenous pathogenic bacteria and inherent putrefactive bacteria in the intestine, reduce the growth and accumulation of putrefactive substances in the intestine, improve the intestinal environment, promote intestinal peristalsis, and prevent constipation and diarrhea.

2 Reduce blood fat and cholesterol

Fructooligosaccharide is an excellent water-soluble dietary fiber. Through the action of intestinal bifidobacteria, FOS can be fermented to produce propionic acid, which hinders the synthesis of cholesterol, promotes the conversion of cholesterol into bile acids, increases bile acid excretion, and can effectively reduce The amounts of serum cholesterol, triglycerides, and free fatty acids have a good effect on improving a series of cardiovascular diseases such as hypertension and arteriosclerosis caused by high blood lipids.

3 Promote vitamin synthesis and improve immunity

Fructooligosaccharides can promote the natural formation of multiple vitamins and folic acid, produce a large amount of S-TGA immune proteins and other immune substances, effectively prevent bacteria from adhering to the host's intestinal mucosal tissue, and a large number of bifidobacteria can also produce intestinal immune cells. Strong stimulation increases the number of antibody cells, activates the activity of macrophages, and strengthens the human immune system.

4. Protect liver

After Bifidobacterium absorbs fructooligosaccharides, it rapidly proliferates and acts on spoilage bacteria such as Escherichia coli, Salmonella and Clostridium, reducing the production of toxic metabolites. At the same time, it quickly excretes toxic metabolites from the body, reducing the burden on the liver, and plays a It has the effect of protecting the liver, and the intake of fructooligosaccharides will not cause an increase in blood sugar levels and insulin.

5. Promote the absorption of minerals and the discharge of toxic wastes in the intestines

Fructooligosaccharide has the function of binding metal ions with dietary fiber. In the acidic environment of the large intestine, the solubility of minerals such as calcium, magnesium, and zinc increases, and their biological effectiveness is also improved. Fructo-oligosaccharides can maintain the moisture of the intestinal wall, increase the moisture and acidity of the intestinal cavity contents, and at the same time cultivate the intestinal wall of Bifidobacterium to form a bacterial film protective barrier, thus accelerating intestinal peristalsis and producing defecation reflex, which is beneficial to indole and nitroso in the intestine. Emission of carcinogenic toxic wastes such as amines.

6. Prevent obesity

Fructose and fructose in fructo-oligosaccharides are not hydrolyzed by enzymes in human saliva and small intestinal digestive enzymes, are difficult to digest and absorb internally, and have low caloric value. Therefore, intake of fructooligosaccharides will not cause obesity. 

Applications of fructooligosaccharides

Based on its good physical and chemical properties and physiological effects, fructooligosaccharides have been widely used in food, health products, feed and other industries.

1 Application in general food

Fructo-oligosaccharide has low caloric value, good thermal stability, and has the characteristics of inhibiting starch aging. Therefore, it can partially replace sucrose and be added to baked goods such as biscuits, breads, and moon cakes. Baked food added with fructooligosaccharides has a pure sweetness, good shape and color, and has the effect of promoting the proliferation of beneficial bacteria, which is both nutritious and healthy.

In addition, fructooligosaccharides also have excellent solubility, excipients and other properties, and can be used in the production of chewing gum, peanut gummies and other candies.

2 Application in health products and special medical foods

Based on the aforementioned physiological effects of fructo-oligosaccharide, it is used in a variety of health products. In the domestic market, there are many health care products using fructooligosaccharides as raw materials or excipients, such as Baolingbao prebiotics, Jinchantong compound prebiotics, Aliguo prebiotics, Perfect brand fructooligosaccharide sea buckthorn tea, Xiu Xiu Pharmaceutical Shuchang oral liquid, Duoweisheng brand iron zinc calcium amino acid fructooligosaccharide oral liquid, etc.
