Common sow thistle tea making method capable of removing harmful matter

Abstract

The invention relates to a common sow thistle tea making method capable of removing harmful matter. The common sow thistle tea making method comprises the following steps of 1, fresh leaf washing, 2, pesticide removal, 3, fixation, 4, fermentation, 5, spread cooling, 6, baking, 7, aroma increase, 8, high-temperature steaming and 9, cooling and baking. After common sow thistle leaves subjected to the step 8 are subjected to forming or bulk packaging, the common sow thistle leaves enter a cooling room to be baked, the temperature is controlled to range from 18 DEG C to 28 DEG C, baking and cooling are carried out for 20-25 days, and then quality testing and warehousing are carried out. The common sow thistle tea making method has the advantages that many tedious toxin removal methods for tea trees, tea gardens and the like can be omitted, the pesticide residues of dry tea can be successfully removed, and after detection of a tea pesticide residue tachymeter, the tea exporting standard is completely met; a reducing function is further achieved, the foreign taste of the dry tea can be removed, commercial application is achieved, much labor force is saved, the effect and efficiency are remarkable, and the method is suitable for green tea, black tea, white tea, oolong and the like.

Description

technical field [0001] The invention relates to a preparation method of chicory tea which can remove harmful substances. 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.

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
