Abstract

The invention discloses a preparation method of a starch-based zinc-rich nutrition enhancer. The method comprises: preparing starch raw materials into starch milk with a mass percent concentration of 5%-12%, adjusting the pH to 4.5-6.5, stirring in an enclosed container at 95-99 DEG C for gelatinization; cooling, adding debranching enzyme, stirring at 45-65 DEG C for reaction; adjusting the pH to 5.5-7.0, adding alpha-amylase, stirring at 45-110 DEG C for reaction, adjusting the pH to 2.5-3.0, performing enzyme deactivation to obtain an amylase solution; adjusting the temperature to 50-80 DEG C, adding a zinc salt solution, adjusting the pH to 5.0-8.0, stirring for reaction; adjusting the pH to 4.5, cooling to room temperature, performing refrigeration in a refrigerator; and performing acid pickling, washing, drying, and crushing to obtain the product. The product of the invention is rich in zinc trace element, can be used as a food additive to be added into food and health-care food, and has very good improvement effect on nutrition deficiency diseases caused by lack of zinc.

Description

technical field [0001] The invention relates to a production method of modified starch, in particular to a method for preparing a starch-based zinc-rich nutritional enhancer by combining biotechnology and chemical methods. Background technique [0002] Zinc is one of the important trace elements necessary for the human body and animals, and its content is second only to zinc in the trace elements contained in the human body. As early as more than 100 years ago, human beings have known the influence of zinc on life activities, but it was not until the 1960s that they knew that zinc is also an essential nutrient for the human body, thus creating a new era of research on the biological function of zinc . Zinc has important biological functions for the human body, such as promoting growth and development, maintaining normal sense of taste, smell, vision, participating in regulating the immune function of the body, and accelerating the regeneration of wounded tissues. Zinc is a...
