Embodiment Construction

[0042] The technical solutions of the present invention will be described in detail below through specific examples.

[0043] A production method of polydextrose with high purity and high degree of polymerization, the method of the invention, produces polydextrose with a molecular weight of 700-20000.

[0044] Including ingredients, polymerization, end reaction, decolorization, membrane separation, ion exchange, concentration, spray drying steps, the specific production steps are as follows:

[0045](1) Ingredients: Accurately weigh glucose, sorbitol, and citric acid, the weight ratio of glucose: sorbitol: citric acid is 150:18:1, and put them into the reaction kettle;

[0046] (2) Polymerization: Add the prepared materials into the reaction kettle, start stirring first and then feed, the stirring speed is 10r / min, start the vacuum pump, the vacuum degree is ≥-0.095MPa, and the temperature rises to 180-200°C. The polymerization process depends on the motor current. The transm...

Abstract

The invention belongs to the technical field of glucose production and particularly relates to a high-purity and high-polymerization-degree glucose production method. The method comprises the steps of material mixing, polymerization, reaction ending, decoloration, membrane separation, ion exchange, concentration and spray drying. By the aid of the method, the production program is simplified greatly, material are not in contact with the outside, secondary pollution and cross pollution of human factors to finished products are prevented or reduced, the product quality is good, and the production cost is low.

Description

technical field [0001] The invention belongs to the technical field of polydextrose production, in particular to a production method of polydextrose with high purity and high degree of polymerization. Background technique [0002] Polydextrose, alias: polydextrin, dextran (Polydextrose), is a polycondensate of D-glucose with random bonds, mainly combined with 1,6-glucosidic bonds. Appearance: white to similar white powder or granule, easily soluble in water, solubility 70%, pH of 10% aqueous solution is 2.5-7.0, no special smell. Polydextrose is used in low-calorie foods, which can partially or completely replace sugar and fat. While reducing food energy, it can maintain the original flavor and texture of food, so that it can arouse consumers' interest and bring exciting results. Satisfying palate enjoyment. [0003] Polydextrose has comprehensive health functions that general insoluble fibers do not have: [0004] Regulating blood lipids: Water-soluble dietary fiber can ...
