Pine needle shaped steam tea pomegranate green tea and preparation method thereof

Abstract

The invention provides a preparation method of pine needle shaped steam tea pomegranate green tea. The method mainly comprises the steps of pomegranate leaf withering, steam fixation, flabellation, drying performed in a shaking mode, twisting and drying. The temperature and humidity control withering mode, the steam fixation mode, and the primary, intermediate and shaping three-time heating twisting mode are adopted, compared with a traditional processing technology, the defects that due to unreasonable spreading, pomegranate leaf tea is bitter in taste, heavy in green grass odour, the penetrating power of dry-heat air is not strong in the process of dry-heat fixation, enzyme activity passivation is not thorough, the fixation effect is not uniform, burnt edges and blisters or red stalks and leaves or the like are likely to appear are overcome, and the defect that tea appearance is thick and strong or the short and broken rate is high due to a traditional rolling mode is overcome, so that the product quality characteristics are greatly improved, and the obtained green tea has the advantages that the dry tea is black green and glossy in color, the appearance is tight, thin, round and straight, the tea is similar to pine needles in shape, the liquor color is limpid and bright, the leaf bottom is light green, bright and uniform, the fragrance is clean and sweet or clean aroma or flowery fragrant, and the taste is mellow and not astringent.

Description

technical field [0001] The invention relates to the technical field of tea, in particular to a pine needle-shaped steamed pomegranate green tea and a preparation method thereof. Background technique [0002] Pomegranate (Punicagranatum L.) is a plant of the genus Pomegranate in the Pomegranate family. Its fruit, leaves, and flowers are not only important traditional Chinese medicines in the pharmacopoeias of the past dynasties, but also one of the important medicinal materials in Uyghur medicine, which has considerable application value.

Problems solved by technology

[0004] Chinese patent application ZL03150055.2 discloses a patent titled "a kind of pomegranate tea drink and its preparation method". -75°C) is too low to passivate the activity of enzymes in pomegranate leaves, especially the activity of polyphenol oxidase. Zhang Lihua et al. compared the content of polyphenols in pomegranate leaves and the fresh leaves of tea trees and the oxidation of polyphenols. Enzyme activity, the results show that the polyphenol content and enzyme activity of pomegranate fresh leaves are higher than that of tea tree fresh leaves. Therefore, a large part of the polyphenols in the green tea produced by the green tea processing method in patent ZL03150055.2 will Oxidized in the greening and subsequent processes, the health effects of pomegranate leaf tea such as anti-oxidation are reduced, and at the same time, chlorophyll is also lost due to enzymatic oxidative degradation

(2) In the patented pomegranate green tea method, cold kneading is adopted for kneading, and the viscous pectin content in pomegranate leaves is lower than that of fresh tea tree leaves. At the same time, pomegranate leaves are more brittle than fresh tea tree leaves of the same tenderness. The leaves are fragile and not easy to shape

Therefore, the pomegranate leaf tea made by cold kneading method will inevitably have thick and loose strands if the sliver rate is guaranteed; Effect
