Embodiment 1

[0024] (1) After drying, pulverizing, adding water and cooking the citrus pomace, adding potassium permanganate with a concentration of 5% for decolorization, its weight ratio to the citrus pomace solution is 1:10, the pH value is 7, For 50min, the orange pomace solution becomes a colorless solution;

[0025] (2) When the citrus pomace solution in step (1) is cooled to 35-45° C., add compound enzyme, carry out enzymolysis and filter, the weight ratio of the compound enzyme and citrus pomace solution is 1:100, and the enzyme The solution reaction time is 3h, and the pH value is 4, wherein the weight ratio of various enzymes is neutral protease: lipase: cellulase: pectinase=1:1:4:2;

[0026] (3) adding hydrochloric acid with a concentration of 10% to the filtrate obtained in step (2), the weight ratio to the filtrate is 1:3, and stirring evenly at 40°C;

[0027] (4) Add NaOH with a concentration of 2% to the filter residue obtained in step (3), the weight ratio to the filter re...

Abstract

The invention provides a preparation method of hesperidium pomace dietary fiber. The preparation method comprises steps as follows: (1), hesperidium pomace is dried, smashed and cooked with water, andthen potassium permanganate is added for decoloration treatment; (2), when a hesperidium pomace solution obtained in step (1) is cooled to 35-45 DEG C, complex enzyme is added, and enzymolysis and filtering are performed in sequence; (3), hydrochloric acid is added to a filtrate obtained in step (2) and stirred uniformly; (4), NaOH is added to filter residues obtained in step (3) and stirred uniformly; (5), 95% ethanol is added to the filtrate treated with acid in step (3), and when precipitates are separated out, the precipitates are collected; (6), water-insoluble dietary fiber and water-soluble dietary fiber of the hesperidium pomace obtained in steps (4) and (5) are mixed, a mixture is subjected to vacuum drying, and the hesperidium pomace dietary fiber is obtained. According to the method, the hesperidium pomace is taken as the raw material, waste is changed into wealth, and the economic benefit is remarkable.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a preparation method of citrus pomace dietary fiber. Background technique [0002] Dietary fiber is an important non-nutrient. It is a kind of indigestible part of carbohydrates such as non-starch polysaccharides and oligosaccharides. It can neither be digested and absorbed by the human gastrointestinal tract, nor can it produce energy. However, in recent years, more and more studies have shown that the intake of dietary fiber is closely related to human health, and adequate intake of dietary fiber will reduce the risk of constipation, obesity, diabetes, cardiovascular disease and intestinal cancer. For example, dietary fiber can absorb a large amount of water in the intestinal tract, keep the stool soft, effectively activate the beneficial bacteria in the intestinal tract, promote the proliferation of beneficial bacteria, and create a healthy intestinal ecology, especi...
