Description

Preparation process of partridge tea and tea beverage Technical Field The invention relates to a tea beverage preparation process, in particular to a partridge tea preparation process and a tea beverage containing the partridge tea. Background Partridge tea is a very distinctive tea beverage plant and medicinal plant in Hainan. According to the research on chemical components of partridge tea, 15 polyphenol compounds and 1 alkaloid are separated from 50% ethanol extract of partridge tea, and the effect of clearing heat and detoxicating the partridge tea is not derived from caffeine, but other chemical components contained in the partridge tea. In addition to the basic effects of promoting digestion and removing greasiness, clearing heat and eliminating dampness, promoting the production of body fluid and quenching thirst, the pharmacological activity of the tea alcohol extract is summarized in modern pharmacological researches and is roughly summarized into antibacterial, antiviral, antifatigue, antioxidant and the like. Gynostemma pentaphylla, cucurbitaceae, gynostemma herb climbing plant, thin and weak stem, branches, longitudinal edges and grooves, no hair or short soft hair, and Japanese called Ganchuan tea. The research shows that the gynostemma pentaphylla has various bioactive substances, contains rich gynostemma pentaphylla polysaccharide, flavonoid, saponin, trace elements and the like, contains 14 amino acid components, wherein 6 amino acids are essential amino acids of a human body. The gynostemma pentaphylla has various biological activities, such as regulating the immunity of the organism, resisting oxidation, reducing blood fat, protecting cardiovascular and the like. Semen Scaphii Lychnophori is mature seed of plant of Pinaceae, and has remarkable effects in lowering blood pressure, moistening throat and eliminating phlegm, and is a traditional Chinese medicinal material used as both medicine and food. Modern scientific researches show that the seed coats of boat-fruited sterculia seed contain polysaccharide components such as galactose and pentose, active components such as boat-fruited sterculia seed extract, tannins, phenolic acid and amino acid, and trace elements such as calcium and magnesium, and have various biological activities. Disclosure of Invention Although partridge tea has a long drinking history in Hainan region, the conventional simple processing technology is still reserved in the aspect of processing the partridge tea at present, and large-scale and industrialized production is not formed, so that the application and popularization of the partridge tea are limited to a certain extent. In addition, the tea leaves obtained by the processing method of the tea at the present stage are difficult to maintain the content of active ingredients such as flavone and tea polyphenol, and meanwhile, the taste and the storage stability of the obtained tea beverage are ensured. Therefore, the processing technology of the partridge tea is studied deeply, and the nutrition activity, the taste, the stability and the like of the obtained partridge tea are the technical problems to be solved in the field.
