Puerarin extractive technique and kudzuvine root beverage process

Abstract

The invention provides a technology for extracting puerarin and a process for making kudzu root beverage. The technology for extracting puerarin adopts an ultrasonic multistage advection contact process to carry out extraction, wherein the contact process is as follows: the second stage and the third stage of a three-stage advection contact process for extracting kudzu root adopt ultrasonic wave to assist the extraction; the process for making kudzu root beverage comprises material selection, pretreatment and precooking; during extraction, the ultrasonic multistage advection contact process is adopted to extract kudzu root; finally, the extract is made into kudzu root beverage after centrifugation. The extracting technology is scientific and reasonable and has short extraction time, good effect and strong operability; when the technology is adopted to make kudzu root beverage, the process of the technology has low requirement on equipment and is easy to control along with strong operability, less energy consumption and low production cost; therefore, the technology is suitable for the large-scale production of kudzu root beverage; moreover, manufactured kudzu root beverage has abundant nutrition, convenient eating and delicious and various tastes; therefore, the technology has tremendous economic benefit.

Description

Technical field [0001] The invention belongs to the field of beverage processing, and more specifically relates to a puerarin extraction technology and a pueraria beverage technology. Background technique [0002] Radix Puerariae (Radix Puerariae) is the root of the leguminous plant Pueraria lobata, rich in isoflavone components puerarin, puerarin xyloside, daidzein, daidzein and β-sitosterol, arachidic acid, and contains a lot of starch, its medicine The use value and edible value are extremely high. It is cool in nature, sweet and pungent in taste, enters the lungs, stomach, and spleen meridian, lightly elevates and disperses, has the effects of relieving muscles and reducing fever, promoting body fluid and quenching thirst. It is known as "Asian Ginseng". Pueraria lobata has relatively large output in Hunan, Guangdong, Fujian, Yunnan, Guizhou, Sichuan, Anhui and other provinces and can be used for development and utilization. The traditional use of Pueraria lobata root is gene...

AI Technical Summary

Problems solved by technology

The traditional utilization of puerarin is generally direct food or medicinal use, and its beneficial components such as puerarin cannot be effectively utilized, and it is inconvenient to eat, and the taste is single; and now the extraction methods of puerarin are generally water decoction, alcohol extraction, microwave Auxiliary extraction, etc., but these technologies have the disadvantages of limited extraction efficiency, incomplete extraction, etc., and the effect is not ideal when applied to the kudzu root beverage processing
