Problems solved by technology

[0003] In the light industry, according to the DE value of maltodextrin, it is divided, that is, DE value ≤ 10, ≤ 15 and ≤ 20. The DE value of maltodextrin is determined by the amount of glucose it contains. Therefore, with With the increase of DE value, the degree of hydrolysis of maltodextrin also gradually increases; in order to adapt to different food additive requirements, the difference of DE value is gradually taken as the key research content, but for the production of maltodextrin with low DE value, the existing The process mainly has the following problems: backward equipment and technology, resulting in unstable quality, and large differences in solubility between batches; when the product quality is tested by vacuum suction filtration, the appearance has black spots, yellow spots, etc., and the solubility does not meet the quality requirements ; In addition, filamentous foreign matter often occurs in the product, which affects the quality of the product

Abstract

The invention provides a novel maltodextrin production process, which uses starch as raw materials. Through a liquidation work procedure, a saccharification work procedure, a deslagging and decoloringwork procedure, an ion exchange work procedure, an evaporation concentration work procedure and a spray drying work procedure, maltodextrin with a low DE value is obtained. The DE value of the maltodextrin product is 6 to 8, wherein in the liquidation work procedure, a processing process using three times of spraying, twice enzyme adding and three sections of maintenance is used for processing the starch. The maltodextrin production process has the advantages of practicability and high applicability. The maltodextrin with the low DE value (the DE value is 6 to 8) produced by the maltodextrinproduction process has the advantages that the product quality is stable; the appearance is uniform; no maltodextrin retrogradation occurs.

Description

technical field [0001] The invention relates to the technical field of maltodextrin production, in particular to a novel maltodextrin production process. Background technique [0002] Maltodextrin is a kind of starch derivative without free starch, and its DE value ranges from 5 to 20. Its preparation process is as follows: using high-quality starch as raw material, after being hydrolyzed by amylase, refined, concentrated, and spray-dried to form a powder Products, referred to as MD in English. Maltodextrin has high viscosity, strong thickening, good solubility, good instant solubility, good carrier, small fermentation, low moisture absorption, no peculiar smell, low sweetness, easy digestion and absorption by the human body, low heat, low Therefore, it has become one of the most ideal basic raw materials in the food industry, and has been more and more widely used in the paper industry, daily chemical industry, fine chemical industry, and pharmaceutical industry.
