Embodiment 1

[0041] Take peanut shells, peanut stems and peanut roots that are mold-free and moth-free, clean them with running water, and dry them in a blast drying box at 80°C. The dried raw materials are crushed with a plant crusher, and the crushed material is finely ground by a food processor , The finely ground product is passed through a 50-mesh sieve, and the under-sieve is collected as peanut powder for extracting dietary fiber; the peanut powder obtained is added to the citric acid extractant with a mass percentage of 3%, in an ultrasonic extractor, the ultrasonic frequency is 25kHz, Ultrasonic power 210W and ultrasonic temperature 70℃ for 60min, vacuum filtration treatment, retain the filtrate, and the filter residue is subjected to two ultrasound and vacuum filtration treatments under the same conditions, and the filtrate is vacuum rotary evaporated in a 60℃ water bath three times to obtain the first concentration The first concentrated solution is used as the extract of water-so...

Embodiment 2

[0043] Take peanut shells, peanut stems and peanut roots that are mold-free and insect-free and clean with running water and dried in a blast drying box at 80°C. The dried raw materials are crushed with a plant crusher, and the crushed material is finely ground by a food processor , The finely ground product is passed through a 50-mesh sieve, and the under-sieve is collected as peanut powder for extracting dietary fiber; the peanut powder obtained is added to the acetic acid extractant with a mass percentage of 1%, in an ultrasonic extractor, the ultrasonic frequency is 40kHz, ultrasonic Power 270W and ultrasonic temperature 80℃ for 90min, vacuum filtration treatment, retain the filtrate, the filter residue is then subjected to two ultrasonic and vacuum filtration treatments under the same conditions, and the three suction filtrates are combined and vacuum rotary evaporated in a 70℃ water bath to obtain concentrated solution 1. Concentrate 1 is used as the extract of water-solub...

Embodiment 3

[0045] Take peanut shells, peanut stems and peanut roots that are mold-free and insect-free and clean with running water and dried in a blast drying box at 80°C. The dried raw materials are crushed with a plant crusher, and the crushed material is finely ground by a food processor , The finely ground product is passed through a 50-mesh sieve, and the under-sieve is collected as peanut powder for extracting dietary fiber; the peanut powder obtained is added to the citric acid extractant with a mass percentage of 10%, in an ultrasonic extractor, the ultrasonic frequency is 45kHz, Treatment with ultrasonic power of 300W and ultrasonic temperature of 80℃ for 120min, vacuum filtration treatment, retain the filtrate, and the filter residue is subjected to two ultrasound and vacuum filtration treatments under the same conditions, and the three suction filtrates are combined and vacuum rotary evaporated in a 65℃ water bath to obtain concentrated solution 1 , Concentrate 1 is used as 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 hasthe 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 diabetesmellitus, 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 asfunctional 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 the 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. British nutrition expert Chuwell put forward the concept of "food fiber" in 1972, and in his two famous nutrition reports, pointed out that the incidence of modern civilization diseases is inversely proportional to the consumption of dietary fiber; eating high fiber content To a certain extent, his diet can prevent hyperlipidemia, hypertension, heart disease, diabetes, and obesity. These two iconic 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 nu...
