Preparation method of black wolfberry composite ferment liquid

Abstract

The invention relates to a preparation method of black wolfberry composite ferment liquid. The preparation method comprises the following steps: (S1) selecting mature and normal-flavor black wolfberryand red dates, removing kernels from the red dates, cutting the red dates into blocks, cleaning, and airing for later use; (S2) soaking green tea into boiling water, and filtering, so as to obtain tea liquid; (S3) weighing 400 parts of the black wolfberry, 40-60 parts of the red dates and 10-20 parts of the tea liquid, adding honey, and uniformly mixing, so as to obtain a ferment raw material; (S4) adding water into the ferment raw material, and pulping, so as to obtain black wolfberry composite juice; (S5) injecting the black wolfberry composite juice into a utensil, carrying out high-pressure sterilization, and cooling; (S6) inoculating saccharomycetes under an aseptic condition, fermenting, so as to obtain a primary fermentation solution; (S7) inoculating primary fermentation solutionunder an aseptic condition, and carrying out secondary fermentation, so as to obtain a secondary fermentation solution; (S8) carrying out settling, extraction, filtration and pomace removal on the secondary fermentation solution, so as to obtain the composite ferment liquid. The preparation method has the advantages that the preparation process is simple, the immunity and disease resistance of a human body can be remarkably improved, and the composite ferment liquid has relatively strong oxidation resistance, rich nutrition and good taste.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and in particular relates to a preparation method of black wolfberry compound enzyme liquid. Background technique [0002] The research on "enzyme" began at the beginning of the 20th century. The word "enzyme" first originated in Japan, which means "enzyme", a biological catalyst, and later developed to Europe, America, and Taiwan. The product is also called "enzyme", which is a fermented product commonly sold and used in the market. Since it was introduced to the mainland in 2007, it has quickly become a hot spot in the market. [0003] Fermentation can not only improve some bad flavors of the fermentation substrate itself, but also produce some new active ingredients to enhance the health benefits of "enzyme" products. Enzyme products contain a variety of beneficial nutrients for the human body, including polyphenols (flavonoids, anthocyanins, catechins, phenolic acids, tannin...

Problems solved by technology

[0008] At present, in the prior art, it is recorded about the enzyme product with black wolfberry as a single raw material. The alcohol fermentation time of this technology is 3-9 days long, and a large amount of alcohol is produced, which is not suitable for daily drinking of drivers; the fermentation time of lactic acid bacteria is short, and the fermentation temperature is 30 -35°C, no more than 12 hours, less metabolites; fermentation using supernatant to inoculate and ferment, which will cause problems such as easy sedimentation and premature aging of the bacteria. In addition, the antioxidant capacity of this enzyme product is weak
