Embodiment Construction

[0015] Specific description is given below by the following examples:

[0016] A kind of preparation method of kudzu root isoflavone powder of the present invention comprises:

[0017] (1) Take kudzu root as raw material, after drying and crushing, add 70% ethanol, the solid-liquid ratio (g / mL) of kudzu root to 70% ethanol is 1:30~1:10. Then cellulase and protease were added for enzymolysis, wherein the mass ratio of cellulase and protease was 1:3-1:1, the enzymolysis temperature was 55-65°C, the enzymolysis time was 50-65 min, and the pH of the system was 6. The total amount of cellulase and protease is 2-4% of the kudzu root ethanol solution by mass volume ratio. Then concentrated under reduced pressure and freeze-dried to obtain kudzu root isoflavones.

[0018] (2) Mixing the Pueraria isoflavones prepared in step (1) with β-cyclodextrin and soybean lecithin, the mass ratio of Pueraria isoflavones, β-cyclodextrin and soybean lecithin mixture is 3-6:1, Wherein, the mass ra...

Abstract

The invention discloses a preparation method of kudzu root isoflavone powder. The preparation method of the kudzu root isoflavone powder includes: using kudzu roots as raw materials, drying, smashing, adding ethanol, then adding cellulose and protease to perform enzymolysis, decompressing and concentrating, and freezing and drying to obtain kudzu root isoflavone; mixing the kudzu root isoflavone, beta-cyclodextrin and soybean lecithin, adding water to make 1000mL kudzu root isoflavone emulsion, and performing ultrasonic processing for 20 minutes; atomizing the kudzu root isoflavone emulsion which is processed by ultrasonic into liquid drops through a spray gun, freezing and curing rapidly after the liquid drops are contacted with compressed nitrogen, placing cured samples in a vacuum freeze drying apparatus to be dried, and obtaining the kudzu root isoflavone powder. The kudzu root powder manufactured by the method fills the blank that no kudzu root powder exists on the domestic market, enzyme treatment is matched with digestion so as to extract flavonoid materials effectively, processing steps are reduced, efficiency is improved, kudzu root flavone can be kept maximally by using a spray freeze drying technique, and products with high economic value and health care value can be obtained.

Description

technical field [0001] The invention relates to the field of production and processing of food health products, in particular to a preparation method of kudzu root isoflavone powder. Background technique [0002] Pueraria lobata is the hypertrophic tuber of Pueraria genus Fabaceae, which contains a variety of flavonoids and is the main active ingredient in Pueraria lobata. Modern medical research shows that the flavonoids in kudzu root can relieve spasm and relieve pain, enhance blood flow in the brain and coronary arteries, improve blood circulation in the heart and brain, reduce blood sugar and blood lipids, enhance myocardial contractility, prevent nervous headaches, resist oxidation and enhance the body's immune system. Immunity etc. [0003] Existing powder preparations often use spray drying, but spray drying is a high-temperature process, especially for kudzu flavonoids, which are easy to destroy the active ingredients, and are not conducive to long-term storage. C...
