Embodiment Construction

[0014] Tea is a traditional drink in our country. Although there are different drinking methods in different eras, they all use blisters to extract active ingredients from water. The contents of various ingredients in different teas are not the same, but the types are basically the same. With the improvement of modern analysis techniques, people have discovered a variety of compounds from tea extracts, among which the main active ingredients are a variety of organic compounds including tea polyphenols and phosphorus, potassium, sulfur, magnesium A variety of trace elements, etc.

[0015] Tea polyphenols have a variety of physiological activities, especially anti-oxidation, which can scavenge free radicals, thereby regulating the cardiovascular system and anti-radiation. Medicines and health products containing tea polyphenols have gained more and more attention.

[0016] The extraction of tea polyphenols generally involves the extraction of fresh tea leaves and the extractio...

Abstract

The invention discloses a method for processing a tea polyphenol extracting raw material. The method comprises the steps of picking, spreading for airing to remove surface moisture of tea leaves, performing fixation by use of microwave, carrying out quick freezing and unfreezing a plurality of times in a circulating manner, crushing, extracting and the like. The method for processing the tea polyphenol extracting raw material has the advantages that tea leaf cells are completely crushed, soluble materials in the tea leaves can be dissolved in extract liquid well, and therefore, the tea polyphenol yield of the raw material per unit can be increased.

Description

technical field [0001] The invention belongs to the field of post-treatment of tea leaves, and in particular relates to a method for processing tea polyphenols extraction raw materials. Background technique [0002] This invention belongs to the project research results of the national 863 project tea garden intelligent key technology and equipment development (2012AA10A508), and the project executors are Wang Jinhe, Zhu Zhongding and Chen Peng. [0003] Tea polyphenols have been widely used in health care products, medicine and other fields. The extraction of tea polyphenols currently has a variety of methods such as solvent method, precipitation method, and supercritical fluid extraction. These methods are all based on the principle of leaching and then separating the tea polyphenols contained in tea leaves. The current prior art all pay attention to the extraction rate of tea polyphenols from the extract, but few people pay attention to the residual rate in tea raw mater...
