Abstract

The invention relates to a method for modifying water-soluble dietary fibers of millet bran. The method for modifying water-soluble dietary fibers of millet bran comprises the following steps: 1, carrying out air blasting pretreatment on the millet bran; 2, modifying the air blasting pretreated millet bran through an ultrasonic-microwave synergism technology; and 3, preparing water-soluble dietaryfibers through an enzyme-gravimetric technology: transferring a reaction solution obtained in step 2 to a GDE enzyme culture digestor, carrying out enzymatic hydrolysis at a pH value of 4.0-6.0 at anenzymatic hydrolysis temperature of 60-95 DEG C for 20-30 min, transferring the reaction product of the enzymatic hydrolysis into a CSF6 filtering device, concentrating the obtained filtrate, and carrying out alcohol precipitation, centrifugation and freeze-drying to obtain millet bran water-soluble dietary fiber powder containing 10.3% of the water-soluble dietary fibers. The method greatly increases the content of the millet bran water-soluble dietary fibers to meet the requirements of high-quality dietary fibers, and effectively solves the problem of low utilization rate of the millet bran.

Description

1. Technical field

[0001] The invention relates to the technical field of grain processing, in particular to a method for modifying rice bran water-soluble dietary fiber. 2. Background technology

[0002] With the improvement of people's living standards in our country, great changes have taken place in everyone's diet structure. The intake of high-calorie foods such as animal fat and protein is too much, while the intake of coarse grains is getting less and less, resulting in more and more patients with various chronic diseases. . Some physiological effects of dietary fiber have been confirmed by scientific experiments, such as beneficial to gastrointestinal health, preventing obesity, reducing the incidence of cardiovascular disease and diabetes, etc. In order to prevent the occurrence of chronic diseases, the intake of dietary fiber should be appropriately increased. The reasonable intake recommended by the U.S. Food and Drug Administration (FDA) is 20-35g per day for a...
