Technology of using broken rice noodles to prepare anti-digestion powder and application of the powder

Abstract

The present invention provides a technology of using broken rice noodles to prepare anti-digestion powder and an application of the powder. The technology comprises the following steps: firstly, a rice noodle cutting machine is used to control the lengths of the broken rice noodles within 1-4 cm; then the broken rice noodles are placed into a mechanical crusher to be crushed, broken rice noodle powder is taken to be dispersed into a phosphate buffer solution, then the solution is preheated in a boiling water bath, the preheated solution is cooled, then alpha-amylase and glucoamylase are taken at a ratio of (1:3)-(3:1), the taken two enzymes are added into the solution, a catalytic reaction is conducted for 1-2 h, then, the solution is subjected to an enzyme deactivation at the boiling water bath, the treated solution is cooled, the cooled solution is centrifuged, the centrifuged solution is washed, and the washed solution is dried to obtain the anti-digestion powder, and the anti-digestion powder is subjected to an ultra-fine grinding to be 20-40 [mu]m in particle sizes. The technology solves the problem that in the production process of the rice noodles, the values of the broken rice noodles cannot be effectively used. The technology of using the broken rice noodles to prepare the anti-digestion powder and the application of the powder belong to the field of food processing.

Description

technical field [0001] The invention relates to a preparation process and application of an anti-digestion powder, belonging to the field of food processing. Background technique [0002] Resistant starch is a new concept that has emerged in recent years. In 1992, the World Food and Agriculture Organization defined it as "starch and its degradation products that are not absorbed in the small intestine of healthy people" based on expert advice. Recent studies have initially proved that resistant starch cannot be digested and absorbed by the small intestine and provide glucose. It can be fermented by physiological bacteria in the colon to produce short-chain fatty acids and gas, stimulating the growth of beneficial bacteria. Because of its physiological functions in regulating blood sugar, lowering blood lipids, reducing the incidence of colon cancer, and controlling body weight, resistant starch has become a hot spot in the research of food nutrition and health care functions...
