Selenium-enriched orange peel probiotics product

Abstract

The invention provides a preparation process of a selenium-enriched orange peel probiotics product. The preparation process comprises the specific steps of adding soybean meal cakes into orange peelsfor crushing, adding flour, adding water, adding a saccharifying enzyme to carry out saccharification for 3-5 hours, then adding sodium selenite and zinc oxide powder, inoculating baker yeast after high-temperature sterilization, carrying out aerobic fermentation, and carrying out centrifugalization to obtain a supernate and a precipitate; adding water into the precipitate, then adding neutral protease and calcium chloride, thermally insulating at 30-40 DEG C for 2-4 hours, then adding crushed mulberry powder, stirring the mixture for 30-60 minutes, and filtering the mixture to obtain a filtrate I and pomace I, adding all supernate after high-temperature sterilization of the pomace I, and carrying out aerobic fermentation at 25-30 DEG C for 24-48 hours, and filtering the mixture to obtaina filtrate II; and after high-temperature sterilization of fresh milk, adding lactic acid bacteria and bifidobacteria for fermentation for 24-48 hours, mixing and stirring the mixture with the filtrate I at 10-15 DEG C for 3-6 hours, then adding the filtrate II, and uniformly mixing the mixture and storing the mixture at 0-5 DEG C.

Description

Problems solved by technology

[0012] At present, mulberry products are simply added to various dairy products or extracted with functional pigments, or directly used as raw materials for fermentation to produce various beverage products, which will cause a large amount of water-soluble pigments to be oxidized and destroyed during the growth of microbial fermentation. The main function of mulberry Excessive loss of active ingredients and other problems, the purpose of the present invention is to solve the deficiencies and defects of the prior art, and provide a method for preparing a probiotic product with high utilization rate and rich nutrition
