Soluble dietary fiber literally means cellulose that can be dissolved in water. Today, let's talk about FOS in detail, one of the water-soluble dietary fibers.

What is FOS? Fructose-oligosaccharide (FOS) is a water-soluble dietary fiber and one of the most representative prebiotics recognized by the scientific community. It acts on the front segment of the colon (ascending colon) and is preferentially fermented by bifidobacterium and effectively promotes the proliferation of bifidobacterium.

 

Fructose-oligosaccharides (FOS) have two sources. One is derived from chicory in Europe, and the other is mainly derived from sucrose in Asia. However, there are also some FOS from chicory in China at present.

 

What is the function of FOS?

 

1, Low calorific value. Fructose-oligosaccharides cannot be directly digested and absorbed by the human body, but only be absorbed and used by intestinal bacteria, so its calorific value is low, and will not lead to obesity, then indirectly has the function in weight loss. It's also a good sweetener for diabetics.

 

2, As it is not used by oral bacteria (streptococcus mutans), it has anti-caries effects.

 

3, Fructose-oligosaccharides can selectively proliferate the beneficial bacteria such as Bifidobacteria and lactobacillus in the intestinal tract, make the beneficial bacteria as dominant in the intestinal tract, inhibit the growth of harmful bacteria, reduce the toxic substances (such as endotoxin, ammonia, etc.). It has protective effect on intestinal mucosa cells and liver, so as to prevent the occurrence of pathological bowel cancer and enhance the body immunity.

 

4, Reduce the content of cholesterol and triglyceride in serum.

 

5, Promotes the absorption of nutrients, especially calcium.

 

6, Prevent diarrhea and constipation.

 

Application of Fructose-oligosaccharides (FOS)

 

1, Fructose-oligosaccharides (FOS) are not easy to be absorbed by the human body, the calorie value is very low, will not lead to obesity, can produce diet food, low calorie food; Fructose-oligosaccharides have low sweetness and are popular for producing sugar-free or low-sugar foods.

 

2, Fructose-oligosaccharides (FOS) are used in lactic acid bacteria drinks to solve the problem of lactose tolerance, increase the content of water-soluble absorbable calcium, and make dairy products more digestible and absorbed.
