Preparation technology of kidney bean dreg dietary fibers

Abstract

The invention discloses a preparation technology of kidney bean dreg dietary fibers. Kidney bean dregs serve as main raw materials of the kidney bean dreg dietary fibers, and final products are obtained through raw material pretreatment, alkali treatment, washing, enzyme hydrolysis, enzyme deactivation, washing, dynamic high pressure micro-jetting treatment, spray drying and ultra-micro pulverizing. The preparation technology of the kidney bean dreg dietary fibers comprises the steps of raw material pretreatment, alkali treatment, washing, enzyme hydrolysis, enzyme deactivation, washing, dynamic high pressure micro-jetting treatment, spray drying and ultra-micro pulverizing. The dietary fibers prepared by using the preparation technology are high in solubility, are in a milk white color, are fine and smooth in taste, can serve as directly-eaten dietary therapy type dietary fiber products and can further serve as food additives or dietary fiber enhancers to be added in foods such as yoghourt and bread.
