Embodiment 1

[0041] Take peanut shells, peanut stalks and peanut roots that are free from mildew and rot, wash them with running water, and dry them in a blast drying oven at 80°C. The dried raw materials are crushed with a plant grinder, and the crushed materials are finely ground by a food processor. , the finely ground thing is passed through a 50-mesh sieve, and the under-sieve is collected as peanut powder for extracting dietary fiber; the gained peanut powder is added with a citric acid extractant with a mass percentage content of 3%. Ultrasonic power 210W and ultrasonic temperature 70 ℃ for 60 minutes, vacuum filtration treatment, retain the filtrate, the filter residue is subjected to ultrasonic and vacuum filtration treatment twice under the same conditions, and vacuum rotary evaporation of the filtrate three times in a 60 ℃ water bath to obtain the first concentration Liquid, the first concentrated solution is used as the extraction solution of water-soluble dietary fiber, and the...

Abstract

The invention belongs to the field of food processing, and relates to a peanut dietary fiber ultrasonic wave or microwave auxiliary extraction and purification method which comprises the following steps of: carrying out ultrasonic wave or microwave auxiliary extraction on the prepared peanut powder, and obtaining water-soluble dietary fiber by protein precipitation, membrane filtration concentration, column chromatography, absolute ethyl alcohol precipitation, centrifugation and drying; and after ultrasonic wave or microwave treatment, carrying out complex enzyme hydrolysis and decoloring refining on the peanut powder, and obtaining insoluble dietary fiber. The prepared water-soluble dietary fiber product has 50-90% of non-starch polysaccharide, and the insoluble dietary fiber product has the purity of 80-95%, so that the peanut dietary fiber has the physiological functions of preventing coronary heart disease, controlling and treating obesity, adjusting blood sugar, treating diabetes mellitus, regulating blood fat, preventing hypertension, adjusting the functions of intestines and stomach, preventing cancers, removing exogenous noxious substances and the like, and can be taken as functional food material or health food. The method can be used for obtaining the peanut dietary fiber with high content, purity and activity, and is suitable for industrialized production.

Description

technical field [0001] The invention belongs to the field of food processing, and relates to a method for assisting extraction and purification of peanut dietary fiber by using ultrasonic waves or microwaves. Background technique [0002] The term "dietary fiber" was proposed by British epidemiologist Phipsley in 1953. Trewell, a British nutritional expert, proposed the concept of "food fiber" in 1972, and pointed out in two famous nutrition reports that the incidence of modern civilization diseases is inversely proportional to the consumption of food fiber; A healthy diet can prevent hyperlipidemia, hypertension, heart disease, diabetes, obesity, etc. to a certain extent. These two landmark reports opened the prelude to human research on dietary fiber. Dietary fiber refers to the sum of plant cells, polysaccharides, lignin and other substances in food that cannot be digested and absorbed by human endogenous enzymes. This definition includes a large number of components in...
