[0014] The preparation method of sugarcane dietary fiber of the present invention specifically comprises the following steps:

[0015] A. Pre-treatment: After drying and crushing the sugarcane by-products remaining from sugarcane processing, add distilled water to cook at 110-120°C for 30-40 minutes, then concentrate, dry and crush the raw materials, then slowly spray and add water while stirring, and add water to the raw materials containing Adjust the water volume to 100-150%, then stop stirring and take out the raw material, seal it for 5-30 minutes, then put the raw material into the steam explosion device, raise it to 0.8-1.0Mpa in 1-4 minutes, keep the pressure for 50-80s, and release the pressure instantly , take out the raw material and add NaOH solution with a mass percentage concentration of 2.5-3, extract at a power of 160-200W for 25-30min to obtain an extract, then centrifuge the extract at 5500-6000r / min for 3-4min and then filter, and take the filter residue as a...

Abstract

The invention discloses a preparation method of sugarcane dietary fibers. The preparation method comprises the following steps of pretreatment, preparation of a semi-finished product, purification andpost-treatment. The invention also discloses the sugarcane dietary fibers prepared by the preparation method of the sugarcane dietary fibers. According to the method provided by the invention, duringpretreatment, a mode with combination of high-temperature cooking treatment, steam explosion treatment and ultrasonic treatment on raw materials is adopted, structural organizations of the raw materials can be effectively destroyed, and inclusions of the raw materials are fully exposed; by combining with impurity removal treatment, non-dietary fiber components in the raw materials are further lowered, and the raw materials after pretreatment are beneficial to strengthening the enzymolysis effect of cellulase or a compound enzyme of the cellulase and hemicellulase and also enables enzymolysisto be more full, so that the purity of a finished product is improved, and the palatability of the finished product can be effectively improved; and the finished product is purified after enzymolysis,the purity is further improved, and the finished product has the advantage of high purity. The sugarcane dietary fibers provided by the invention also have the advantages of small fiber particle sizes, strong water-holding capacity and strong swelling capacity.

Description

technical field [0001] The invention belongs to the technical field of dietary fiber preparation, and in particular relates to a preparation method of sugarcane dietary fiber and the sugarcane 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,...
