Problems solved by technology

However, the traditional diet in my country is mainly based on plant foods, and there is no lack of dietary fiber, so the research and development of dietary fiber is not enough.
It can be said that the research and development of dietary fiber in my country is still in its infancy, and no large-scale processing enterprises have been formed.

Embodiment 1

[0028] Take peanut shells, peanut stalks and peanut roots without 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 crusher, and the crushed materials are passed through a 50-mesh sieve, and the collected The following is used as peanut powder for extracting water-soluble dietary fiber; add 3 times (the mass ratio of peanut powder to acetone) acetone to the peanut powder, shake it in a constant temperature water bath at 30°C for 30 minutes, filter with suction, discard the filtrate, keep the filter residue 1, add 3 times (the mass of peanut powder to the volume ratio of ethanol) ethanol, oscillating treatment in a constant temperature water bath at 30°C for 30 minutes, suction filtration, discarding the filtrate, and retaining the filter residue 2; The mass percentage of protease is 0.2%, the mass percentage of α-amylase is 0.2%, the pH value of the mixed enzyme solution is 6.0, the mixed ...

Embodiment 2

[0030]Take peanut shells, peanut stalks and peanut roots without 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 crusher, and the crushed materials are passed through a 50-mesh sieve, and the collected The following was used as peanut powder for extracting water-soluble dietary fiber; peanut powder was added with 5 times (the mass ratio of peanut powder to acetone volume) acetone, oscillated in a constant temperature water bath at 50°C for 90 minutes, suction filtered, the filtrate was discarded, and the filter residue 1 was retained, and 5 times (the mass of peanut powder to the volume ratio of ethanol) ethanol, oscillating treatment in a constant temperature water bath at 50°C for 90 minutes, suction filtration, discarding the filtrate, and retaining the filter residue 2; The mass percentage of protease in the medium is 1.0%, the mass percentage of α-amylase is 1.0%, the pH value of th...

Embodiment 3

[0032] Take peanut shells, peanut stalks and peanut roots without 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 crusher, and the crushed materials are passed through a 50-mesh sieve, and the collected The following was used as peanut powder for extracting water-soluble dietary fiber; peanut powder was added with 4 times (the mass ratio of peanut powder to acetone volume) acetone, oscillated in a constant temperature water bath at 40°C for 60 minutes, suction filtered, the filtrate was discarded, and the filter residue 1 was retained. times (the mass of peanut powder to the volume ratio of ethanol) ethanol, shake in a constant temperature water bath at 40°C for 60 minutes, filter with suction, discard the filtrate, and keep the filter residue 2; The mass percentage of protease in the solution is 0.6%, the mass percentage of α-amylase is 0.6%, the pH value of the mixed enzyme solution is...

Abstract

The invention discloses a peanut water-soluble dietary fiber enzymatic extracting method which comprises the steps of: pretreating the prepared peanut powder by acetone, alcohol, protease and alpha-amylase, and hydrolyzing by using cellulose for three times; and concentrating hydrolysis liquid and then precipitating by absolute ethyl alcohol, centrifuging and drying to obtain the water-soluble dietary fiber. The product prepared by the invention contains 30-60% of non-starch polysaccharide, can reduce the content of low density lipoprotein (LDL) cholesterol in the blood, promotes the growth and the propagation of probiotics group in the intestinal tract, and can be taken as functional food for preventing and alleviating symptom as well as treating diseases such as cardiovascular diseases and the like in an auxiliary way. The method is low in production cost, high in fiber content and suitable for industrialized production.

Description

technical field [0001] The invention relates to an enzymatic extraction method of peanut water-soluble dietary fiber, which belongs to the field of food processing. Background technique [0002] 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 food such as cellulose, hemicellulose, lignin, pectin , modified cellulose, mucilage, oligosaccharides, pectin, and other small components such as wax, cutin, and cork. Although dietary fiber has no nutritional value, it can treat and prevent many diseases of modern civilization and is essential to the normal metabolism of the human body. Therefore, dietary fiber has been widely valued by experts from different fields, including medical scientists, nutritionists, dietitians, food scientists, biochemists, and scientific decision makers related to food regulations ...
