Problems solved by technology

[0008] Based on the above five polydextrose production process patents, their common shortcomings are: complicated process, incomplete or excessive polymerization, low product purity, poor color, etc., and are not suitable for large-scale industrial production
At present, some products in my country contain about 7% monosaccharides and disaccharides. The degree of polymerization of glucose is low, and the proportion that can be absorbed by the human body is relatively large, and the effect in promoting intestinal peristalsis is not obvious. Improvements in glucose production technology to improve the molecular weight distribution of polydextrose and minimize the content of available sugars

Abstract

The invention relates to a method for producing polyglucose, which comprises the following steps: (1) blending glucose, sorbitol and citric acid in a weight percent range of 80-90: 1-5: 9-15, then performing stirring reaction on the mixture for 3 to 8 hours in a reaction kettle at the temperature of between 150 and 200 DEG C under the negative pressure of between 0.02 to 0.06MPa, and performing polymerization reaction on the mixture to obtain a polymer; (2) adsorbing and decoloring the polymer; and (3) spray-drying the polymer to obtain a finished product of the polyglucose. The producing method solves the difficult problems of complex existing production process, incomplete polymerization reaction, low product purity, poor color and luster and the like, and has the advantages of rich raw material source, simple process, high purity of the finished product, adaptability for large-scale industrialized production and the like; and electric heating is adopted during processing, and the water vapor produced in the polymerization reaction is condensed and discharged, so the whole production process reflects the advantages of no waste gas emission, no pollution, little consumed energy, simple process and energy conservation.

Description

technical field [0001] The invention belongs to the field of food additives, and relates to food dietary cellulose, especially a production method of polydextrose. Background technique [0002] Dietary fiber is a nutrient that is not easy to be decomposed by digestive enzymes. It mainly comes from the cell walls of plants and sugars in natural foods. According to the degree of solubility in water, it can be divided into two basic types: water-soluble fiber (poly Glucose) and non-water-soluble fiber, water-soluble fiber is better than non-water-soluble dietary fiber in preventing and treating cardiovascular disease, diabetes, obesity, etc. And the fastest excretion of cholesterol, not only can help control the blood sugar and cholesterol in the blood beyond the optimal level, but also help diabetic patients reduce insulin and triglycerides, which has long attracted the attention of nutritionists, known as "" The seventh nutrient". [0003] Fiber food is known as "the oasis ...
