Method for preparing dietary fibers from wastes and byproducts generated in tangerine processing

Abstract

The invention relates to a method for preparing dietary fibers from wastes and byproducts generated in tangerine processing, and belongs to the technical field of production methods for dietary fibers. The method comprises the following steps of: 1) pretreating the wastes and the byproducts generated in tangerine processing; 2) pretreating tangerine fruit peels; 3) performing enzymolysis; 4) squeezing and filtering; 5) drying and crushing; 6) extruding, modifying and activating; and 7) performing superfine grinding at low temperature. The method is simple, convenient to operate, low in production cost and stable in quality of products and is suitable for industrial production, and the water retention property and expansibility of the tangerine dietary fibers are superior to those of the ordinary dietary fiber products; by adding natural fruit and vegetable ferment powder and five-cereal ferment powder which have special nutrients, dietary fibers from wastes and byproducts generated in tangerine processing have the effects of improving the immunity of a human body, activating cells, promoting metabolism and the like, and can be used as a replenisher of the dietary fibers, functional foods and the like, so that the economic value of tangerines is improved, and the comprehensive utilization of tangerine resources is realized.

Description

technical field

[0001] The invention belongs to the technical field of dietary fiber production methods, and in particular relates to a method for preparing dietary fiber by using citrus processing waste and by-products. Background technique

[0002] Dietary fiber is mainly polysaccharides and lignin that cannot be digested and absorbed by the human body, and is called the "seventh largest nutrient". Studies have shown that dietary fiber has very important physiological functions for human health. Dietary fiber can be divided into soluble dietary fiber (Soluble dietary fiber, SDF) and insoluble dietary fiber (Insoluble dietary fiber, IDF) according to its water solubility. SDF has the functions of lowering human serum cholesterol, preventing gallstones, diabetes, hypertension and heart disease, etc. effect; while IDF has a good effect on preventing obesity, constipation, and intestinal cancer.
