Description

Technical Field

[0001] The invention relates to the technical field of corn starch processing equipment, in particular to a pretreatment screening device for preparing multi-benefit raw corn starch. Background Art

[0002] The main carbohydrate intake by the human body on a daily basis is starch, which provides 40-60% of the energy for daily activities. According to the speed of digestion in the body, starch is divided into fast-digestible starch (RDS), slowly-digestible starch (SDS) and resistant starch (RS). RS cannot be digested and absorbed by the small intestine. After entering the large intestine, it will change the structure and composition of the intestinal flora and produce components such as short-chain fatty acids that are beneficial to the human body. And then promote human health. On the other hand, existing research defines prebiotics as substances that can change the structure of intestinal flora, provide energy for intestinal flora, and produce metabolites that are beneficial to the body. It includes resistant starch, polysaccharides, polyphenols, phenolic acids and many other ingredients.
