Abstract

The invention relates to a method for preparing selenium-enriched healthy tea with high tea polyphenol and theanine. The method comprises the following steps: dissolving tea polyphenol, theanine and polysaccharide selenate in water at 80-100 DEG C to prepare a solution; dipping the raw tea in the prepared solution to obtain the functional crude tea product; and dehydrating, rolling and vacuum-drying the functional crude tea product to obtain the functional finished tea product or dehydrating and vacuum-drying the functional crude tea product to obtain the functional finished dry tea product. The method has the following beneficial effects: the content of tea polyphenol in the tea can be increased by nearly 90-130%, the content of theanine can be increased by 50-150%, the content of polysaccharide selenate (namely organic selenium) can be increased by 70-200%, the weight percentage of caffeine in the functional tea can be reduced below 0.5% and the functional tea still has the style of the traditional fixation tea.

Description

technical field [0001] The invention relates to the technical field of tea deep processing, in particular to a preparation method of high tea polyphenols, high theanine and selenium-enriched health care tea. Background technique [0002] Tea polyphenols account for 15% to 35% of the dry matter of tea. It is one of the main components of tea with health care functions. It has excellent antioxidant activity and significant ability to scavenge free radicals. It has significant effects on diseases and other aspects, and also has detoxification and anti-radiation effects, which can effectively prevent radioactive substances from invading bone marrow. It is also one of the main components that form the color and aroma of tea. [0003] Theanine is a unique free amino acid in tea, which accounts for 1% to 2% of the dry matter of tea. Theanine has the functions of inhibiting the excitement caused by caffeine, relieving nervous tension, delaying exercise fatigue, improving memory, a...
