Abstract

The invention discloses a granulum starch with the functions of nutrition enrichment and fat simulation and a preparation method thereof. The preparation method comprises the following steps of: dispersing starch in acid solution to prepare starch milk, hydrolyzing by means of stirring in thermostatic waterbath, filtering and washing to obtain a filter cake a; adding water into the filter cake a to prepare starch milk, adjusting the PH value of the starch milk to be 8.0-9.0 with alkaline solution, adding ocentyl succinic, keeping the PH value of the reaction system to be 8.0-9.0, keeping the PH value of the reaction system to be invariable within 0.5h, adding divalent metal salt or trivalent metal salt to perform neutralization reaction, centrifuging, washing and drying to obtain a sample b; and dispersing the sample b in an alcohol-water medium, and ballmilling to obtain the granulum starch. The granulum starch has the characteristics of short ballmilling time, small granularity, even distribution of grain diameter, large specific surface area, a certain lyophobic emulsifying property and metallic element nutrition enrichment, and can be widely used for high value-added special meals food such as fat-replaced food, fat-simulated food and the like.

Description

technical field [0001] The invention belongs to the field of starch modification and its deep processing, and in particular relates to a small-grain starch with functions of nutrition strengthening and fat simulation and a preparation method thereof. Background technique [0002] Excessive intake of fat will endanger human health and increase the incidence of cancer. Fat is closely related to obesity, cardiovascular disease, diabetes and gallbladder disease. Therefore, many countries are very concerned about the intake of fat. Developed countries have widely used fat substitutes to replace part of the fat in food formulations. The so-called fat simulation refers to carbohydrates or proteins that can simulate the taste and texture of fat in food. Among them, starch-based simulated fat comes from a wide range of sources and has the most products. [0003] Small granular starch refers to a type of starch with a particle size of less than 10 μm, especially starch with a partic...
