Embodiment 1

[0041] A preparation method for regulating the walnut protein peptide-selenium chelate of intestinal flora, comprising the following steps:

[0042] (1) After the walnut kernels are degreased by hydraulic cold pressing, the obtained walnut meal is crushed and passed through a 60-mesh sieve to obtain walnut meal powder, and then added to the walnut meal powder according to the ratio of material to liquid 1:3 Distilled water, after stirring evenly, add oil-degrading bacteria with 3% weight of walnut meal according to the weight percentage, after stirring evenly, place the first ultrasonic treatment at a frequency of 150W and a temperature of 28°C for 50min, and the first ultrasonic treatment ends The first fermentation treatment was carried out at 28°C for 6 hours to obtain the first fermentation material; wherein, the oil-degrading bacteria were composite bacteria composed of Pseudomonas aeruginosa, Bacillus amyloliquefaciens and Candida crassa species, the weight ratio of Pseu...

Abstract

The invention belongs to the technical field of food processing, and particularly relates to a preparation method of a walnut protein peptide-selenium chelate for regulating intestinal flora. The method comprises the following steps: (1) degreasing walnut kernels, and carrying out primary fermentation by using grease degrading bacteria to obtain a first fermentation material; (2) adding sucrose, serratia aromatica and zymomonas mobilis into the first fermentation material according to a certain ratio, and carrying out secondary fermentation to obtain a second fermentation material containing prebiotics; (3) carrying out enzymolysis on the second fermentation material by using a compound enzyme to obtain protein peptide; (4) adding selenium-enriched yeast into the obtained protein peptide to carry out selenium chelating treatment; and (5) carrying out pre-freezing, vacuum freeze-drying, packaging and sterilization on a selenium chelating material obtained in the step (4). In the invention, a selenium element can be provided for a human body, and a grease content is further reduced in a preparation process so that an extraction rate and purity of protein and a conversion rate of protein polypeptide are correspondingly improved, and an effect of regulating intestinal flora is also achieved.

Description

【Technical field】 [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of walnut protein peptide-selenium chelate for regulating intestinal flora. 【Background technique】 [0002] Walnut is one of the four major dried fruits in the world. Walnut is unattractive in appearance, but its nutritional value and medicinal value are very high. "Compendium of Materia Medica" records that walnut is warm in nature, sweet in taste, non-toxic, and has the functions of invigorating the stomach, nourishing blood, moistening the lungs, Rejuvenation and other effects. Modern scientific analysis shows that walnut kernel is rich in protein, various amino acids, trace elements, vitamins, etc., and is a rare and strong tonic. The main deep processing method of walnut is the production of walnut oil, which mainly adopts pressing method, which will produce a large amount of by-products—walnut meal, which is currently mainly used ...
