Problems solved by technology

[0004] At present, when producing maltose powder in China, the content of maltose contained in it is not stable, which cannot meet the demand for maltose powder with high maltose content, and corn starch is often used as raw material for maltose processing in industry, and rice is also rich in starch. The early indica rice with poor edible quality has thin and thin grains, deep longitudinal grooves, no luster, light and rough taste, and is not suitable for daily consumption, resulting in serious storage pressure and burdening the national finance. Therefore, the present invention provides a kind of Method for preparing maltose sugar powder with high maltose content by using indica rice as raw material

Abstract

The invention relates to a preparation method of maltose powdered sugar with high maltose content. The method comprises the steps of pretreatment, acid enzyme liquefaction, impurity removal, saccharification and refining, indica rice with poor eating quality is used as a raw material to produce maltose, and fungus alpha-amylase, pullulanase and maltotriase are added during saccharification for synergistic effect; the saccharification reaction is performed for a period of time, dextranase is added for a hydrolysis reaction, and enzyme deactivation is performed to obtain saccharification liquid; by controlling the conditions such as a liquefied DE value and the addition amount of various enzymes, the production cost can be reduced while starch is catalyzed to be degraded to generate maltose, and better conditions are provided for maltose formation in the subsequent saccharification step; and the dextranase deeply catalyzes and hydrolyzes glucan into glucose or oligosaccharide, non-maltose parts are removed during refining, the purity of maltose is further improved, the filterability of maltose sugar products is improved, and the viscosity is reduced. The maltose sugar powder with the maltose content being 90% or above can be prepared through the method of the invention, and the application prospect in the sugar product field is considerable.

Description

technical field [0001] The invention relates to the technical field of production, in particular to a method for preparing maltose sugar powder with high maltose content. Background technique [0002] Maltose is a disaccharide composed of two glucose units linked by α-1,4 glycosidic bonds. Maltose is rich in nutrition, sweet and delicious, and has many functions such as detoxifying and beautifying, nourishing the spleen and Qi, moistening the lungs and relieving cough. [0003] Maltose powder is a product obtained by grinding maltose into powder. It has extremely rich nutritional value. It can not only provide energy for human metabolism, but also stabilize intestinal bacteria and promote the proliferation of bifidobacteria, thereby reducing the impact of toxic metabolites on the body. In addition, when maltose powder is added to other products, it also has the effects of making it difficult to agglomerate, volume expansion, instant dissolution, etc., and can be used in var...
