Abstract

The invention provides lotus leaf dark tea and a producing method thereof. The dark tea mainly comprises the following components in parts by weight: 5-15 parts of a lotus leaf extract, and 85-95 parts of dark tea. The two components are matched according to a specific proportion and mutually cooperated, the lotus leaf dark tea component has effects for adjusting body metabolism, accelerating lipid metabolism, enhancing stomach function, and promoting digestion, and long term drinking of the product has good fat-reducing efficacy. The lotus leaf extract is added into the fermented dark tea, so that in the respect of mouthfeel, the product has heavy and thick, and mellow tastes of the dark tea, and light delicate fragrance of lotus leaves.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a lotus leaf dark tea and a preparation method thereof. Background technique [0002] Traditional teas include black tea, green tea, white tea, yellow tea, and dark tea, each with its own characteristics and efficacy. With the development of the times, new teas emerge in endlessly with various names, such as grapefruit black tea, chrysanthemum Pu'er tea, lotus leaf black tea and so on. Lotus leaf dark tea is one of them, and the current production method of lotus leaf extract in lotus leaf dark tea is: use dried and crushed lotus leaves as raw materials, use cellulase pretreatment, dilute hydrochloric acid extraction, ultrasonic assisted extraction 1. Combine the extracts, alkalinize and adjust the PH value, concentrate and evaporate water to the extract with specific gravity D=1.15, let cool, stir with 10 times the amount of chloroform, let stand, separate layers, continue to extr...
