Abstract

The invention relates to the technical field of preparation of dietary fibers, in particular to a method for preparing dietary fibers by means of peanut shells. The method for preparing the dietary fibers by means of the peanut shells specifically comprises the steps that with the peanut shells used as raw materials, smashing is conducted, fermentation is conducted twice, enzymolysis is conducted, residue-liquid separation is conducted, centrifugal separation of filter liquor is conducted, filtrating concentration is conducted, freeze drying is conducted, and then water-soluble dietary fibers are obtained; filter residues are decolored, filtered, washed, vacuum-dried and smashed, so that insoluble dietary fibers are obtained. The method for preparing the dietary fibers by means of the peanut shells is simple, and the purity and the yield of the obtained dietary fibers are high.

Description

technical field [0001] The invention relates to the technical field of dietary fiber preparation, in particular to a method for preparing dietary fiber using peanut shells. Background technique [0002] The term dietary fiber did not appear in nutrition before 1970. According to the definition of "GBZ 21922-2008 Basic Terms of Food Nutrients", dietary fiber refers to the polymers of naturally occurring, extracted or synthetic carbohydrates in plants. , whose degree of polymerization DP≥3, cannot be digested and absorbed by the small intestine of the human body, and has health significance for the human body. Including cellulose, hemicellulose, pectin, inulin and other dietary fiber monomer components. Dietary fiber is essential to a healthy diet. Fiber plays an important role in maintaining a healthy digestive system. Adequate fiber intake can also prevent cardiovascular disease, cancer, diabetes, and other diseases. Specifically, according to research, dietary fiber With ...
