Multifunctional slowly digestible starch and preparation method and application thereof

Abstract

The present invention belongs to the field of non-chemical modification and deep processing of starch, and specifically discloses multi-functional slowly digestible starch and a preparation method and an application thereof. The specific steps of the preparation method are as follows: the starch is prepared into starch milk at a starch content of 10-40% and the starch milk is heated at 70-95 DEG C for 30-60 min; fatty acids are added at a mass percentage of 5-25% of starch dry bases, the temperature is kept at 50-60 DEG C, and a stirring is conducted for 20-60 min; and then fat-soluble phenols at a mass percentage of 5-20% of the starch dry bases is added, the materials are stirred continuously for 10-40 minutes, after the stirring, the mixture is slowly cooled to a room temperature, the cooled mixture is washed with ethanol, the washed mixture is dried, the dried mixture is pulverized, and the pulverized mixture is sieved to obtain the multifunctional slowly digestible starch. The multifunctional slowly digestive starch has the slow digestion function, can effectively remove free radicals in body, and synergistically treats or prevents incidences of diabetes, obesity and other chronic diseases.

Description

technical field

[0001] The invention belongs to the field of non-chemical modification and deep processing of starch, and specifically relates to a multifunctional slow-digesting starch and its preparation method and application. In particular, it involves functional products compounded with starch, fatty acids, and fat-soluble phenolic substances, which are used as food additives, health products, and functional foods for the prevention of chronic diseases. Background technique

[0002] In recent years, with the change of people's rhythm of life and the improvement of the provincial capital, the incidence of chronic diseases such as obesity and diabetes is increasing year by year. According to the statistics of the World Health Organization, there are currently more than 150 million diabetic patients, and there are about 50 million in my country, of which type 2 diabetic patients account for 97%. Type 2 diabetes mellitus is a chronic syndrome characterized by disordered su...
