What is the role of resistant dextrin in dietary fiber in canteen?
The function of resistant dextrin has the following aspects:

1, laxative effect

Resistant dextrin is different from standard starch, but more like resistant starch. It hydrolyzes in the upper part of digestive tract, the rest enters the large intestine, about three quarters slowly ferment in the large intestine, and finally is excreted, which has the function of moistening intestine and relaxing bowels.

2, inhibit the rise of blood sugar after meals.

Intake of resistant dextrin can cause hypoglycemia and blood insulin reaction. Therefore, as a carbohydrate that slowly releases energy, it can partially or completely replace other carbohydrates, such as sugar and starch, and can inhibit the increase of postprandial blood sugar.

3. The function of improving lipid metabolism

Resistant dextrin can not only increase the fiber content in food, but also help to delay the recurrence of hunger, which is also good for losing weight. ?

4. It can promote mineral absorption.

It can promote the absorption rate of calcium, magnesium, iron and zinc, and is beneficial to the absorption of nutrients in the body.

Resistant dextrin is made of starch, which is a low-calorie glucan, extracted and refined from the indigestible components of baked dextrin by industrial technology, and belongs to low-molecular-weight water-soluble dietary fiber. As a low-calorie soluble food raw material, it has broad development prospects in the food industry.

Resistant dextrin is white to light yellow powder, slightly sweet, with no other peculiar smell and good water solubility. 10% aqueous solution is transparent or light yellow, and its pH value is 4.0~6.0. The viscosity of resistant dextrin aqueous solution is very low, and the viscosity value changes slightly with the change of shear rate and temperature. Resistant dextrin has low heat, heat, acid and frost resistance.
