[0030] c. Enzymatic hydrolysis

[0031] Add amylase to the sterile solution obtained in step b until the mass fraction of amylase is 3%, enzymatically hydrolyze at 70°C for 10 hours, then add glucoamylase until the mass fraction of glucoamylase is 3%, and the enzyme is at 60°C. Dissolve for 8 hours; then increase the temperature to 90°C for 90 minutes, and then cool to 32°C to obtain an enzymatic hydrolysis solution; where amylase is a mixture of a-amylase and b-amylase at a mass ratio of 1:1

[0032] d. Fermentat...

Embodiment 2

[0035] The specific steps of the preparation method of Pueraria lobata wine are as follows:

[0036] a. Pretreatment

[0037] Take fresh kudzu root, wash, cut into pieces, add water equivalent to 4 times the weight of kudzu root, and homogenize to obtain kudzu root homogenate;

[0038] b. Sterilization

[0039] Sterilize the kudzu root homogenate obtained in step a at a temperature of 100°C for 60 minutes, then cool to 55°C, and adjust the pH to 5.5 to obtain a sterile solution;

[0040] c. Enzymatic hydrolysis

[0041] Add amylase to the sterile solution obtained in step b until the mass fraction of amylase is 1%, enzymatically hydrolyze at 60°C for 18 hours, then add 1% glucoamylase, and hydrolyze 10 at a temperature of 55°C. Hours; then raise the temperature to 100°C for 40 minutes, and then cool to 30°C to obtain an enzymatic hydrolysate; wherein amylase is a mixture of a-amylase and b-amylase at a mass ratio of 3:1;

[0042] d. Fermentation

[0043] The enzymatic hydrolysate obtained...

Embodiment 3

Abstract

The invention discloses a preparation method of Radix Puerariae wine. The preparation method comprises the following steps: collecting fresh Radix Puerariae, cleaning, cutting into pieces, adding water, and performing homogenate to obtain a Radix Puerariae homogenate liquid; sterilizing the Radix Puerariae homogenate liquid at 70-110 DEG C for 5-120 minutes, cooling to 50-65 DEG C, and regulatingthe pH value to 5-7 to obtain a sterilized solution; adding amylase into the sterilized solution until the mass percentage of the amylase is 0.01-5, performing enzymolysis at 50-90 DEG C for 0.5-24 hours, adding glucoamylase until the mass percentage of the glucoamylase is 0.01-5, and performing enzymolysis at 50-70 DEG C for 4-12 hours; then increasing the temperature to 70-110 DEG C, holding the temperature for 20-150 minutes, and cooling to 20-60 DEG C to obtain an enzymolysis solution; and finally adding saccharomyces cerevisiae into the enzymolysis solution until the mass percentage of the saccharomyces cerevisiae is 0.01-0.05, fermenting at 24-40 DEG C for 5-10 days, and filtering to obtain the Radix Puerariae wine. The preparation method is simple; and the prepared Radix Puerariae wine is high in Puerarin content and has an alcohol degree of 15-35, and can be applied to adjuvant therapy for diseases such as hypertension, angina pectoris, coronary heart disease, hyperlipidemia and the like.

Description

technical field [0001] The invention relates to the field of food, in particular to a preparation method of kudzu root wine and kudzu root wine prepared by the preparation method. Background technique [0002] Pueraria ( Radix Puerariae ) is the root of Pueraria mirifica, a perennial vine of the leguminous family. It is cool in nature, sweet and pungent in taste, and is a dual-purpose resource for medicine and food identified by the Ministry of Health. Pueraria lobata is rich in starch, puerarin, puerarin-7-xyloside, daidzein, daidzein, arachidic acid and other substances, and has the reputation of "Asian ginseng". Modern medical research has found that puerarin can lower blood pressure, lower blood lipids, lower blood sugar, dilate blood vessels, increase blood flow in the brain and coronary arteries, and has significant adjuvant therapeutic effects on hypertension, angina pectoris and coronary heart disease. At present, there are many technologies for puerarin processing...
