Embodiment Construction

[0009] Crush and sieve 1000 grams of corn husks, add 3 times the volume of water, heat and cook for 15 minutes to soften, then add liquefied amylase at a rate of 35 enzyme activity units per gram of corn husks, and adjust the pH value to 6 , keep stirring under the condition of 70°C for 2 hours, remove the contained starch, then add protease at the ratio of 14 enzyme activity units per gram of corn bran, keep stirring under the condition of pH value of 7.5 and temperature of 45°C For 2 hours, remove the contained protein to obtain about 550 grams of corn bran from which starch and protein have been removed. Under the condition that the pH value is 4.8 and the temperature is 50°C, add 20 enzyme activity units per gram of corn bran respectively Add xylanase and cellulase produced by mold, stir and enzymolyze for 2 hours to obtain soluble cellulose with a molecular weight of 110,000 and soluble xylan with a molecular weight of 28,000, both soluble dietary fiber liquid, after ultra...

Abstract

The invention discloses a making method of soluble cereal dietary fibers. The method comprises the following steps: mixing various cereal seed coats, crushing, adding water, heating for boiling to soften the various cereal seed coats, adding liquefied amylase, stirring, removing starch contained in the seed coats, adding protease, carrying out heat insulation stirring, removing proteins contained in the seed coats, adding xylanase and cellulase generated by moulds, carrying out enzymatic hydrolysis, and hydrolyzing cellulose and xylan in the cereal seed coats to form soluble cellulose and xylan in order to obtain the soluble dietary fibers. The proportion of soluble components in the dietary fibers is increased through a bioengineering technology in order to improve the physiologic functions of the dietary fibers to human body.

Description

Technical field: [0001] The invention relates to a processing method in the field of cereal food, in particular to a preparation method of soluble cereal dietary fiber. technical background: [0002] Dietary Fiber (DF for short) refers to the general term for high molecular polysaccharides that are difficult to be digested by enzymes in the human body. Dietary fiber has important physiological functions for the human body, including: 1. It has a strong water absorption function, has the effect of preventing intestinal diseases and weight loss; 2. has the function of absorbing organic matter and preventing cardiovascular diseases; 3. It has the function of binding and exchanging cations, and can reduce blood lipids; 4. It can change the physical characteristics of the microbial community composition in the intestinal system. Although dietary fiber cannot be decomposed and absorbed by human digestive enzymes, it is a nutrient that maintains human health and cannot be replaced...
