Problems solved by technology

[0007] In the preparation of maltose syrup, there are mainly the following deficiencies: the DE value is high after starch liquefaction, the existence of glucose in the syrup will affect the quality of the product, such as not conducive to the formation of crystals, the viscosity of the syrup is reduced, etc.; Incompleteness will lead to high content of oligosaccharides with DP≥3
[0008] At the same time, the maltose syrup is viscous, which brings great inconvenience to the storage and transportation of the product. The 98% high-purity maltose prepared by the existing technology needs 85% maltose syrup. After adsorption, ion exchange, membrane separation, Multiple refinements such as crystallization, complex process, high production cost, and limited use (mainly used for injections for patients with diabetes and hypertension in medical treatment)

Abstract

The production process of high purity malt sugar products, including malt sugar syrup, malt sugar alcohol and solid malt sugar, includes the following steps: adding high temperature alpha-amylase into starch milk, spray liquefication, cooling, adding beta-amylase, pullulan enzyme and maltotriose hydrolase for synergetic hydrolysis, and adding medium temperature amylase to saccharify to obtain malt sugar syrup, which may be further processed to obtain other products. The present invention has simple technological process and low production cost, and expands the use of malt sugar syrup.

Description

Technical field [0001] The present invention relates to starch and starch sugar production technology, and more specifically to a method for producing maltose products including high-purity maltose syrup, maltitol and solid maltose. Background technique [0002] High-purity maltose syrup is widely used as a nutritious sweetener and filling agent in the food industry such as high-grade candies, health drinks, oral liquids, malted milk extract, cakes, beverages, etc.; maltose is not easily decomposed by tooth decay bacteria to produce acid and can Prevent the occurrence of dental caries; in the pharmaceutical industry, various Chinese patent medicines and cough syrups can be prepared to moisturize the lungs, treat abdominal pain, and cough. [0003] High-purity maltose syrup can be used to produce maltitol after hydrogenation, and it can also be used to produce pure maltose. High-purity maltitol has anti-caries activity and can be used as a low-calorie functional sweetener, fat sub...
