Abstract

The invention discloses a white tea processing method, and belongs to the technical field of tea processing. The method comprises the following steps: picking fresh tea tree leaves characterized by a bud with a leaf and a bud with two leaves, uniformly spreading the fresh tee tree leaves on a withering tank, disposing at normal temperature to carry out withering, sending the withered leaves to an enzyme deactivating machine, deactivating enzymes, sending the obtained leaves to a microwave enzyme deactivating machine, deactivating enzymes, carrying out tea strip tidying fixing, carrying out drying and fragrance enhancement, screening the obtained tea leaves, and packaging the screened tea leaves to obtain a finished white tea product. Enzyme deactivating treatment of the withered leaves through using the common enzyme deactivating machine and enzyme deactivating treatment of the tea leaves through using microwaves, adopted in the enzyme deactivating step, make beneficial substances, such as tea polyphenol, in white tea, be converted and reserved, so the quality of the white tea is improved.
