Abstract

The invention discloses processing technology of Liupao tea. The technology is characterized in that in a pretreatment process of tea, a ZnO / TiO2 composite nanometer photocatalysis material and an ultraviolet light lamp are matched in order to carry out treatment for tea, and residual pesticides in the tea are degraded; a degrading microorganism agent is added into a piling process, biological enzyme produced from Aspergillus fumigatus, bacillus subtilis and Escherichia coli further degrades residual pesticides which are not degraded in tea; an ultraviolet ray dryer is used for drying in a drying process in order to kill bacteria, fungi and other microorganisms in tea, and provide a processing environment without competitors for subsequent pile fermentation and aging, and at the same time, ultraviolet ray further degrades residual pesticides. The processing technology of Liupao tea can be used for removing residual pesticides, and at the same time the Liupao tea also has 'aroma, heavy flavor, aging, and mellow flavor' with high quality.

Description

technical field [0001] The invention relates to the technical field of tea preparation, in particular to a Liubao tea processing technology. Background technique [0002] Liubao tea is a warm tea, which has the functions of relieving heat and dampness, improving eyesight and clearing heart, helping digestion, etc., and has high nutritional and health value. If there are pesticide residues in tea, it will seriously affect the quality and taste of tea, and even cause serious harm to the human body. Therefore, removing pesticide residues in tea is a major problem in tea production and processing. [0003] The more common pesticide residues detected in tea are mainly organophosphorus pesticides, such as dimethoate, trichlorfon, dichlorvos, demeton, parathion, etc.; organochlorine pesticides, such as lindane, 7054, toxaphene, Chlordane, etc.; carbamate pesticides, such as pirimicarb, carbofuran, carbaryl, propoxur, cartap, etc.; pyrethroid pesticides, such as cypermethrin (Mebac...
