Tea/sweet potato stem tip formula green tea

Abstract

The invention relates to a tea / sweet potato stem tip formula green tea is is characterized by comprising 3-8.5 parts by weight of tea and 1.5-7 parts by weight of sweet potato stem tip, totally 10 parts by weight. The formula green tea is sequentially prepared by the following steps: (1) water removal: evaporating out part of water in the tea and sweet potato stem tip by high temperature until the leaves become soft, thereby creating conditions for twisting and shaping, wherein the water content in the tea and sweet potato stem tip is kept at 12-15%; (2) twisting: kneading the leaves by using an exogenic action to lighten the leaves, and rolling into strips to reduce the volume, thereby facilitating infusion; and (3) drying: evaporating out water, and reshaping. The formula green tea overcomes the defect that the astringency of the green tea can be severe when the tea and sweet potato stem tip are mixed to prepare the green tea in the industry. When being drunk for a long time, the green tea has obviously higher effects on regulating hyperlipemia, cholesterol and hyperglycemia than the existing green tea which is drunk independently. The manufacturing method of the formula green tea is simple, is low in cost and can easily implement large-scale production. The labor cost for picking tea in the prior art is high, so the cost for making tea is enhanced, and the price is higher; and however, the sweet potato stem tip is easier to pick than tea, so the cost price is lower.
