Abstract

The invention provides dendrocalamus latiflorus, gingko and Pu'er instant tea and a preparation method thereof. The preparation method comprises preparation of Pu'er tea soup, preparation of gingko extract, preparation dendrocalamus latiflorus extract, preparation of the dendrocalamus latiflorus, gingko and Pu'er instant tea, a step of sufficiently and uniformly mixing tea leaf concentrated extract and bamboo leaf or gingko leaf concentrated extract, and a step of carrying out beta-cyclodextrin clathration and spraying drying treatment on the extracted liquid. In view of a health function of the prepared dendrocalamus latiflorus, gingko and Pu'er instant tea, particles added with the bamboo leaf extract have the anti-oxidization and sterilization effects can be realized, particles added with the gingko leaf extract have the effects of appetizing and tonifying spleen, tonifying yin and nourishing blood and preventing and treating cardiovascular and cerebrovascular diseases; in view of appearance and mouth feel, particles added with the bamboo leaf extract have a relatively shallow color and slight faint scent; particles added with the gingko leaf extract have a slightly deep color and relatively slight aroma; and the dendrocalamus latiflorus, gingko and Pu'er instant tea is a novel health Pu'er tea beverage. The source of the raw materials is wide, the price is cheap, the extracting method is simple, the maneuverability is strong, the extraction efficiency is high, the mouth feel of the instant tea is light and the effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of natural product extraction. Specifically, it relates to a pure natural Pu'er instant tea powder prepared by taking Yunnan Pu'er tea as a raw material and adding extracts of ginkgo and hemp bamboo, and a preparation method thereof. Background technique: [0002] As we all know, Pu'er tea is a traditional famous tea in China, its main components are tea polyphenols, alkaloids, vitamins, amino acids, aromatic substances, etc. Various health benefits.
