Problems solved by technology

Secondly, due to the presence of a large amount of starch in kudzu root, the beverage product is prone to turbidity or precipitation, which affects the sensory quality of the product
Finally, in the production process, due to improper processing conditions, the dissolution rate of flavonoids is low or destroyed, reducing the nutritional value of the product
The above problems have always been the technical problems that have plagued kudzu root beverage production enterprises, and are also the technical bottlenecks that limit the development of kudzu root beverages.

Abstract

The invention discloses sugar-free radix puerariae clear juice drink and a production method thereof. The production method is characterized by comprising the following steps: by taking fresh radix puerariae without removing peel and fibrous roots as a raw material, cleaning, crushing, performing enzymolysis, centrifuging, performing heat treatment, performing secondary enzymolysis, performing refined filtration, blending, sterilizing, filling, sealing, pouring into a bottle, sterilizing, cooling, trapping labels, spraying the codes, boxing, and thus forming the clarified radix puerariae drink with characteristics and flavor of radix puerariae and acid flavor and delicious taste. According to the method, large-scale industrial production can be realized, and the produced radix puerariae drink is clarified and transparent, is rich in content of flavone compounds, is stored, circulated and sold at normal temperature and has long quality guarantee period.

Description

Technical field: [0001] The invention relates to a sugar-free kudzu root clear juice drink and a production method thereof, belonging to the technical field of food production. Background technique [0002] Pueraria lobata is a resource for both medicine and food. Radix Puerariae, cool in nature, sweet and pungent in taste, has the effects of relieving muscle, reducing fever and promoting body fluid. Pueraria lobata is rich in nutrients. In addition to containing about 20% starch, Pueraria lobata is also rich in calcium, zinc, iron, copper, selenium, phosphorus, potassium and more than 10 kinds of trace elements necessary for the human body, various amino acids and vitamins. In addition, kudzu root also contains flavonoids, such as puerarin isoflavones and puerarin, among which puerarin is a unique flavonoid contained in kudzu root. The presence of flavonoids makes kudzu root reduce myocardial oxygen consumption, increase coronary and cerebrovascular blood flow, relieve an...
