Abstract

The invention discloses a method for producing black potato starch by utilizing biological degeneration and relates to a method for processing modified starch. The technical problem that a method for producing the black potato starch by adopting a biological degeneration process does not exist at present is solved. The method comprises the specific steps: (1) preparing raw materials, namely removing stone, soil, wood and grass sundries, cleaning and shredding; (2) adding an enzyme preparation, namely spraying an amylase agent on the materials; (3) performing poikilothermic treatment, namely performing the poikilothermic treatment between normal temperature and 15 DEG C below zero; and (4) performing conventional processing, namely grinding, extracting, concentrating, removing sand, refining, dehydrating, drying, packaging finished products and performing other conventional processing links after the color of the materials is completely black. According to the black potato starch produced by adopting the biological degeneration process, the varieties of starch are increased, the starch quality is improved, and the application range of potato processing is widened.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and relates to a processing method of modified starch, in particular to a processing technology for producing potato black starch by utilizing biological modification. Background technique [0002] Potato starch has high viscosity and good water absorption, so it occupies a considerable proportion in food industry applications. With the development of the modern food industry, it is difficult for the simple raw potato starch to meet the requirements of many varieties, and it is helpful for the modified starch to meet the stringent requirements for food raw materials. [0003] Biomodified starch is the use of biological denaturation to change the natural characteristics of starch, making it more suitable for specific food requirements. This kind of starch that has been reprocessed on the basis of the conventional starch production process to change the starch properties is...
