Abstract

The invention provides a preparation method of a pueraria drink. The preparation method of the pueraria drink comprises the following steps of: S1, sieving after cleaning and crushing pueraria, so that pueraria powder is obtained; S2, putting the pueraria powder in ethanol and water mixed solution, performing heating extraction, filtering, concentrating filtrate, and retaining filter residues; S3,extracting the filter residues by using a supercritical fluid extraction technology, so that pueraria extraction oil is obtained; S4, pumping the pueraria concentrated extraction solution and the pueraria extraction oil into an allocation tank, adding steviosin, a food emulsifying agent and a food thickening stabilizer, and adding water for production to supply the volume; and S5, homogenizing and degassing, filling through a vacuum filling machine, performing cover sealing, sterilizing, disinfecting, packaging to form a finished product after cooling, and storing at 4 DEG C. The product in the invention satisfies nutritional requirements of people, and simultaneously, has a health care effect; the product is abundant in nutrition and rich in health care function factors; the original flavour of pueraria is completely retained; the pueraria drink is suitable for people of all classes; and the market prospect of the product is wide.

Description

technical field [0001] The invention relates to the technical field of beverages, in particular to a kudzu root beverage and a preparation method thereof. Background technique [0002] Pueraria lobata, a leguminous plant, is a kind of commonly eaten vegetable in some provinces and regions in southern China. It tastes sweet and cool, and is often used for making soup. It is a plant with the same origin as medicine and food. Its main component is starch, and it also contains about 12% flavonoids, including more than 10 kinds of daidzein, daidzein, puerarin, etc., and contains carrotin, amino acids, coumarins, etc., which can be used as drug application. Li Shizhen, a famous medical scientist in the Ming Dynasty, conducted systematic research on Pueraria lobata, and believed that the stems, leaves, flowers, fruits and roots of Pueraria lobata can be used as medicine. He recorded in "Compendium of Materia Medica": "Ge, sweet, pungent, flat, non-toxic, and mainly cures: quenchi...
