Example Embodiment

[0027] Example 1

[0028] A method for fermenting buckwheat leaf enzyme includes the following steps:

[0029] (1) Choose unfolded buckwheat leaves with bright green color and high natural enzyme content as the main raw material for fermentation.

[0030] (2) Wash twice with pure water, and finally soak with 0.9% NaCl solution, sterilize at low temperature, then drain, and put it into a container that has been cleaned with pure water, about 30% of the volume, and add 5 to the total liquid volume. % Of raw honey is used as fermentation stock for later use.

[0031] (3) Prepare LB medium, activate the original preserved strain, and culture the fermentation broth obtained for about 48 hours for use;

[0032] (4) According to the inoculation ratio of 5%, nectar bacteria, Lactobacillus casei and Lactobacillus plantarum were respectively taken into the fermentation stock solution, and the fermentation was carried out for 7 days, pH value 7.0, temperature 25°C.

[0033] (5) Carry out coarse fi...

Abstract

The invention provides a method for preparing an enzyme beverage from polygonum perfoliatum leaves. The method includes the steps that the polygonum perfoliatum leaves are used as a main fermentation raw material, raw honey and natural springwater provided by the Wuxi hundred-year Shangshui drinks limited company are added, nectar source bacterium, lactobacillus casei and lactobacillus plantarum strains are adopted as fermenting strains, fermenting bacterium liquid is added into a fermentation system, wherein the volume of the fermenting bacterium liquid accounts for 1-5% of the volume of a fermenting stock solution, and fermentation is carried out for about 10 d at the temperature of 25 DEG C-35 DEG C and the pH value of 5.0-8.0 to prepare the polygonum perfoliatum leaf enzyme healthcare beverage. Fermentation of the beverage is complete, various enzymes, vitamins, amino acid and microelement are fully released, and the beverage has the unique flavor of the polygonum perfoliatum leaves, is rich in nutrition and tasty and belongs to the technical field of bioengineering by the adoption of a traditional fermentation technology.

Description

technical field [0001] The invention relates to a production method of leaf enzymes, in particular to a fermentation method of fresh buckwheat leaf enzyme health drinks, and belongs to the technical field of bioengineering. Background technique [0002] The word "enzyme" comes from a Japanese name for enzyme (enzyme), and later the initial biologically active products obtained through microbial fermentation are collectively referred to as enzymes. However, because many manufacturers only focus on fruits, especially adding different fruits, and do not pay attention to the use of fermenting microorganisms and other functional materials, the development and application of enzyme products are affected by their side effects and poor functionality. Although some people think that fruit enzymes claim to have the three major functions of detoxification, beauty, and nourishing qi and blood; they also believe that all health maintenance methods serve qi and blood, and qi and blood com...
