Abstract

The invention relates to the field of food processing, and in particular relates to a method for processing apple-flavored low-coffeine black tea and an apple-flavored low-coffeine black tea product. The method comprises the following steps of grading fresh tea leaves according to a black tea requirement, and withering the tea leaves under a certain humidity and temperature condition; spraying an apple extract solution to the fresh tea leaves and rolling; performing fermentation on the rolled leaves; washing the fermented leaves with hot water; centrifugally dewatering the leaves; shaping the dewatered leaves; drying the tea leaves. According to the method disclosed by the invention, coffeine in the tea leaves can be effectively removed, the coffeine content of a tea raw material is reduced, and the apple flavor can be realized; therefore, the tea has the fruit flavor just like beverage and can meet more market requirements.
