Combined fiber with high water absorption expansibility and high water binding force and preparation method of combined fiber

Abstract

The invention discloses a combined fiber with high water absorption expansibility and high water binding force and a preparation method of the combined fiber, and relates to the field of food or feedformulas. The combined fiber comprises the following components in percentage by weight: 40-60% of konjac flour, 25-35% of carboxymethyl cellulose, and 15-25% of xanthan gum polysaccharide. The preparation method of the combined fiber comprises the following steps: respectively crushing the konjac flour, the carboxymethyl cellulose and the xanthan gum polysaccharide in a crusher, carrying out sieving with an 80-mesh sieve to respectively obtain powder A, powder B and powder C, and uniformly mixing the obtained powder A, powder B and powder C to obtain the combined fiber. The combined fiber cansupplement daily ration fibers with insufficient intake in human and animal foods and daily ration, especially soluble daily ration fiber components with high water absorption expansibility, high water binding force and fermentability, the water absorption expansibility and the water binding force of the raw materials are improved through synergistic interaction, the satiety of human and animalsare improved, therefore, the ingestion behaviors of people and animals are regulated and controlled, and the energy intake of people and animals is regulated.

Description

technical field [0001] The invention relates to the field of food or feed formula, in particular to a composite fiber with strong water-absorbing expansibility and high water-binding capacity and a preparation method thereof. Background technique [0002] Dietary fiber refers to the fiber that cannot be digested in the small intestine of humans and animals and partially or completely reaches the large intestine to be fermented by intestinal microorganisms. According to the source of dietary fiber, it can be divided into dietary fiber of plant origin, synthetic and animal, microbial and fungal origin. According to the chemical composition of dietary fiber, it can be divided into non-starch polysaccharides, resistant oligosaccharides and resistant starch. Depending on how dietary fiber is obtained, it can also be classified as natural or synthetic. [0003] The physicochemical properties of dietary fiber are closely related to its physiological function in the gastrointestin...

AI Technical Summary

Problems solved by technology

The dietary fiber products currently on the market are mainly dietary fibers with poor hydration properties, which have problems such as poor water absorption and swelling and low water binding capacity, and cannot effectively provide satiety and satiety after ingestion, thus It affects the use effect, so improving the water absorption expansion and water binding of dietary fiber will help the use effect of dietary fiber in human food, health products and diet therapy, pet and animal husbandry feed
