Problems solved by technology

[0003] In recent years, with the wide application of maltose syrup, a lot of research has been done on the production process of maltose syrup in China, but most of them have the following problems: (1) The content of maltose syrup is difficult to break through 85%, and it is easy to crystallize during transportation and storage; (2) The saccharification time of the existing process is long, and the risk of bacterial contamination in the later stage of saccharification increases; (3) There is no spray-drying method for maltose powder products with a maltose content > 70%
The above problems limit the popularization and use of maltose

Abstract

The invention discloses a preparation method of maltose powder with maltose content higher than 90%. The preparation method includes the steps: (1) liquefying starch to obtain starch emulsion; (2) saccharifying the emulsion obtained in the step (1) to obtain maltose syrup with the maltose content higher than 90%; (3) drying and milling the maltose syrup obtained in the step (2). Drying and millinginclude agglomerated spray drying and fluidized bed cooling. The preparation method solves the problems of long production cycle, complicated process and low yield of a crystallization process, and further solves the problems of tower sticking, tower pasting and low output of a traditional spray drying production mode.

Description

technical field [0001] The application belongs to the technical field of maltose powder preparation, and relates to a method for preparing maltose powder with a maltose content (on a dry basis) > 90%, in particular to the preparation of maltose syrup from starch milk, which is prepared by agglomeration spray drying and fluidized bed cooling method of maltose powder. Background technique [0002] Maltose has low and mild sweetness and strong palatability. It has excellent characteristics in anti-browning, anti-sand return, moisture retention, thermal stability, and low osmotic pressure in the intestine. Currently, most maltose products are liquid, and the content is low Relatively low (maltose content < 60%), special customers require maltose products with a maltose content > 85%, the liquid is easy to crystallize, and it is difficult to store, transport and use. Maltose products with a maltose content > 90% are easier Crystallized, more unsuitable for liquid syr...
