Problems solved by technology

[0003] There are pesticide residue removal products on the market, and the working environment must be carried out in a liquid (liquid phase). However, dry tea leaves with excessive pesticide residues are not allowed to remove pesticide residues in the liquid phase, because the tea leaves will be leached out immediately when soaked in water. The composition of tea leaves is turned into tea water, and then dried into dry tea. Tea leaves can only be tea dregs, so it is not feasible to remove pesticide residues in a liquid phase environment

[0019] A method for preparing green tea capable of removing pesticides in tea leaves, comprising the following steps:

[0020] a. Cleaning of fresh leaves: the fresh leaves picked are added to edible detergent with purified water and cleaned, spread out after cleaning and placed in a cool place, and dry the leaf surface moisture;

[0021] b. In addition to pesticides: using super oxygen gas to remove pesticide residues in tea leaves will quickly oxidize, decompose, and degrade pesticide residues; the time is 65min, the amount of superoxide is 1000mg / h, and the volume is 2m 3 ; and then transport oxygen through the oxygen generator to remove the peculiar smell of superoxide, and continue to oxidize the pesticide residues on the surface of the dry tea leaves; finally, irradiate the tea leaves with ultraviolet light, which can make bacteria and viruses lose their replication function and decompose some pesticides under the action of ultraviolet rays residual;

Abstract

The invention relates to a green tea preparation method capable of removing pesticides from tea leaves. The method comprises steps as follows: a, cleaning of fresh leaves; b, removal of the pesticides; c, fixation; d, fermentation; e, spreading for cooling; f, roasting; g, aroma increasing; h, high-temperature steaming; I, cooling and roasting: the tea leaves subjected to treatment in the step h are shaped or subjected to bulk packaging, then transferred to a cooling house for roasting at the temperature controlled to range from 18 DEG C to 28 DEG C, roasted and cooled for 20-25 days, then subjected to quality inspection and put into storage. The method has the beneficial effects as follows: multiple tedious toxin removal methods for tea trees, tea gardens and the like can be omitted, the dry tea pesticide residues can be removed successfully, tea completely reaches the tea leave export standard after being tested by a quick test meter for tea leave pesticide residues, the method has a reduction effect, the peculiar smell of dry tea leaves can be removed, a lot of labor is omitted for commercial application, the effect and the efficiency are significant, and the method is applicable to green tea, black tea, white tea, oolong tea and the like.

Description

technical field [0001] The invention relates to a green tea preparation method capable of removing pesticides in tea leaves. Background technique [0002] Tea is an edible beverage that people drink daily, if there are excessive pesticide residues in the tea. It will seriously affect people's physical and mental health and cause immeasurable harm to the human body. Therefore, it is of great significance to remove pesticide residues in tea. [0003] There are pesticide residue removal products on the market, and the working environment must be carried out in a liquid (liquid phase). However, dry tea leaves with excessive pesticide residues are not allowed to remove pesticide residues in the liquid phase, because the tea leaves will be leached out immediately when soaked in water. The ingredients of tea leaves are turned into tea water, and then dried into dry tea leaves can only be tea dregs, so it is not feasible to remove pesticide residues in a liquid phase environment. ...
