Embodiment 1

[0018] 100Kg of powdered kudzu root dry block (puerarin content 1.3%), steamed, fed according to the ratio of kudzu root raw material: distiller’s yeast: water 100:0.8:260, adjust PH6, when adding distiller’s yeast, the water temperature is controlled at 25-28°C, and the feed liquid is stirred Evenly sealed and fermented for 12 days, the wine was distilled to obtain 28 kg of 65-degree liquor.

[0019] Add 300kg of water to the residue after drinking, decoct and extract twice, and combine the extracts. Flow the extract through 120kg ADS-8 resin, the adsorption flow rate is controlled at 1.2-2.5BV / hr; wash with 3BV of water to remove impurities, and then elute puerarin with 3BV of 20% ethanol, the desorption flow rate is 1-1.5BV / hr. After recovering ethanol from the desorption solution, the residue was recrystallized with 80-90% glacial acetic acid to obtain 0.82 kg of crystalline puerarin, which was 97% as detected by HPLC. The dry weight of kudzu root residue is 61kg, which c...

Embodiment 2

[0021] Pueraria mirifica dry slices 100Kg (puerarin content 2.5%), steamed, feed according to Pueraria raw material: distiller’s yeast: water ratio of 100:1:260, adjust PH6, control water temperature at 25-28°C when adding distiller’s yeast, stir the feed liquid Evenly sealed and fermented for 15 days, the wine was distilled to obtain 20 kg of 65-degree liquor.

[0022] Add 300kg of water to the residue after drinking, decoct and extract twice, and combine the extracts. Flow the extract through 120kg AB-8 resin, the adsorption flow rate is controlled at 1.2-2.5BV / hr; after washing with 3BV of water to remove impurities, then elute puerarin with 3BV of 20% ethanol, the desorption flow rate is 1-1.5BV / hr. After recovering ethanol from the desorption solution, the residue was recrystallized with 80-90% glacial acetic acid to obtain 1.52 kg of crystalline puerarin, which was 97.2% as detected by HPLC. The dry weight of kudzu root residue is 67kg, which can be used in feed industr...

Abstract

The invention relates to the field of plant products application, in particular to a kudzuvine root comprehensive processing and utilization scheme. The scheme solves the problems in present kudzuvine root processing and utilization that products are concentrated on a single component such as starch or flavone, and the kudzuvine root resources can not be utilized well. The scheme breaks through a mindset in the present technical filed and comprises two steps that edible ethanol is prepared by adopting glycolysis starch, and then the kudzuvine root is extracted and prepared. Water serves as solvent in the process of extraction of the kudzuvine root, and a conventional method that 60% to 80% ethanol must be adopted so as to achieve the purpose of effective extraction caused by coexistence of starch is different from the kudzuvine root comprehensive processing and utilization scheme. Three products or raw materials are generated in the process of kudzuvine root extraction, the purpose of making full use of the kudzuvine root is achieved, and therefore the kudzuvine root comprehensive processing and utilization scheme is suitable for popularization and application.

Description

technical field [0001] The invention relates to the application field of plant products, and is a scheme for comprehensive processing and utilization of kudzu root. Background technique [0002] Pueraria is a perennial vine of the genus Pueraria genus of the leguminous family. It is divided into two types: Pueraria lobata and Pueraria lobata. It is widely distributed in my country. Pueraria is made from its hypertrophic fleshy roots. The roots of Pueraria lobata and Pueraria pueraria are collectively referred to as Pueraria lobata. It is a commonly used Chinese medicine for both medicine and food. Efficacy, used for the treatment of exogenous fever and headache, high blood pressure and neck pain, thirst, thirst, impermeable measles, hot dysentery, and diarrhea. Because kudzu root is rich in starch, isoflavones and calcium, selenium, iron, copper, phosphorus, potassium and more than ten kinds of trace elements necessary for human body, it is widely used in food, health food ...
