Abstract

The invention discloses a processing method of instant black tea powder. The processing method comprises the following steps of crushing black tea leaves so as to obtain black tea powder, mixing the black tea powder with distilled water, sequentially performing mixing and enzymolysis on the mixture of the black tea powder and the distilled water, cellulases, papain, pectinase and tannase, and finally, performing aqueous extraction, reverse osmosis concentration and vacuum freeze drying so as to obtain instant black tea powder. According to the processing method disclosed by the invention, the black tea leaves are used as raw materials, an instant tea extraction process is improved, the fragrance of the instant tea can be improved, original taste of the tea leaves is reserved, and the preprared instant tea powder is high in instant performance, and pure in fragrance and taste, the fragrance and the taste of the prepared instant tea powder are similar with those of original tea, and the instant black tea powder has the soup color of the original tea. Precipitants are not generated, and the instant black tea powder can be directly drunk, and has important significance in the expansion and the development of markets of the instant tea.

Description

technical field [0001] The invention belongs to the technical field of instant tea processing, and in particular relates to a processing method of instant black tea powder. Background technique [0002] Instant tea, also known as soluble tea, crystallized tea, tea essence, etc., is made by deep processing of tea leaves. Specifically, it is a kind of instant and convenient tea beverage made by concentrating and drying the water-soluble substances of tea leaves. For a long time, traditional instant tea production has focused on changing the extraction process, or processing the extract after extraction to improve the quality of instant tea. The key to the quality of instant tea lies in the guarantee of the extracted raw materials. Poor raw materials can easily lead to deterioration of the quality of the extracted instant tea powder. Therefore, before the instant tea is extracted, the tea raw materials are processed first to improve the quality of the raw materials, which can ...
