Tea/sweet potato stem tip fermented formula oolong tea

Abstract

The tea / sweet potato stem tip fermented formula oolong 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 oolong tea is sequentially prepared by the following steps: withering, shaking, pan-frying, twisting and drying. The formula oolong tea overcomes the defect that the astringency of the oolong tea can be severe when the tea and sweet potato stem tip are mixed to prepare the oolong tea in the industry. The oolong tea provided by the invention completely has no astringency. When being drunk for a long time, the oolong tea has obviously higher effects on regulating hyperlipemia, cholesterol and hyperglycemia than the existing oolong tea which is drunk independently. The manufacturing method of the formula oolong 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. When being drunk for a long time, the formula oolong tea has obviously higher effects on helping gastrointestinal digestion, improving the appetite, promoting urination and eliminating edema than the existing oolong tea which is drunk independently.
