Cleaning method for reducing pesticide residues on tea leaves, namely bacterial liquid cleaning method

Abstract

The invention discloses a cleaning method for reducing pesticide residues on tea leaves, namely a bacterial liquid cleaning method. The method comprises the following steps: (1) completely soaking fresh tea leaves in an acinetobacter calcoaceticus liquid (room temperature is 25 DEG C, bacterial liquid temperature is 30 DEG C) for 24-36h; (2) spreading the soaked tea leaves on drainable equipment,repeatedly conducting spray cleaning with clean water, and then placing the cleaned tea leaves in a spin-washing air drying device for drying, wherein the drying temperature is 25-30 DEG C; and (3) thinly spreading the dried tea leaves on a tea rack for airing, and carrying out subsequent processing on the aired tea leaves by a fixation process. The cleaning method of the invention can effectivelyremove the pesticide remaining on the tea leaves, and the method has less influence on the tea leaves, is high in clean class, and does not damage the active ingredients of the tea leaves, so that the quality of the prepared tea leaves is greatly improved.
