Abstract

The invention belongs to the technical field of tea and particularly discloses a preparation method of frosted mulberry leaf black tea. The preparation method comprises the steps of: 1) collection of raw materials: cleaning and soaking picked frosted mulberry leaves and cutting the frosted mulberry leaves into strips; 2) withering: spreading the frosted mulberry leaf strips in a room for 3-4 h with constant temperature and humidity; 3) rolling; 4) fumigation: fumigating the frosted mulberry leaf strips with a fumigation solution; 5) fermentation: mixing and fermenting the frosted mulberry leaf strips with a fermentation liquid; and 6) drying. The preparation method is easy to carry out. The frosted mulberry leaf black tea has high sensory acceptability, is high in content of effective components, and has good nutritional and health-care functions.

Description

【Technical field】 [0001] The invention relates to the technical field of tea, in particular to a preparation method of frost mulberry black tea. 【Background technique】 [0002] Mulberry is a deciduous perennial woody plant of the Moraceae family. my country is the earliest country in the world to cultivate mulberry trees, with a history of more than 4,000 years.
