Among them, it is widely used in ice cream, dairy products, bread, beverage and other industries. When used in various foods, it usually gives the product technological advantages or health advantages with the characteristics of low energy, high fibre and adjusting intestinal function.
 
1）Low energy: Its molecular structure is very complex and is difficult to degrade. The calorific value of it is only 1 kcal/g, its about 1/4 of general carbohydrates.
 
2）Regulation of intestinal tract: It can promote gastrointestinal peristalsis, effectively proliferate intestinal beneficial bacteria, regulate intestinal flora distribution, improve defecation function, reduce intestinal absorption of glucose, and produce short-chain fatty acids by fermentation in the large intestine.
 
3）Control weight : It can suppress appetite, reduce food intaking, and remove excess fat and energy from the body. In addition, dietary fiber can also limit the absorption of fat in the digestive tract, promote lipid excretion and prevent obesity.
 
4）Regulating blood sugar and lowering cholesterol: It can improve the sensitivity of peripheral tissues to insulin, inhibit secrete insulin and hinder the development of insulin.
 
5）With the increase of the concentration of dietary fiber, the absorption of calcium and iron in intestine tends to increase. TAILIJIE dietary fiber is non-cariogenic because it is not fermented by microorganisms in the mouth.
 
3.The application of TAILIJIE dietary fiber in ice cream
 
In ice cream products, it can replace sugar and fat, and can effectively improve the texture and taste of the product, make the fragrance easy to release; As a soluble dietary fiber, it can improve intestinal health, can make people feel full and so, its easy to control weight.

Formulation2	40	58.51	34.5	1850	344.57	34.7

 
2）Antifreeze effect: TAILIJIE dietary fiber can reduce the freezing point of food and obtain the ideal hardness. Studies have shown that the addition of polydextrose has a certain impact on the expansion rate and melting resistance of ice cream. At the same time, it has a certain low-temperature protection effect to protect products from the destructive physical effects of freezing.
 
3）Moisturizing effect: dietary fiber can improve the anti-aging property of the product to a certain extent and play a moisturizing role.
 
4. Market prospect of dietary fiber ice cream
 
As a kind of healthy food ingredient, Tailijie dietary fiber `s market has a very prominent space for development. Dietary fiber products will also have a broad consumer market, and the demand for dietary fiber as a functional ice cream raw material will also increase greatly.
