Problems solved by technology

[0007] Because both oolong tea and sweet potato leaves have an excessively astringent taste, there is a prejudice in the tea industry that the two cannot be mixed to make tea. It will be thicker, which will further affect the quality of oolong tea and affect the drinking habits of some people who are afraid of astringency

Embodiment 1

[0041] The semi-fermented formula oolong tea with potato tips for tea is composed of tea leaves and sweet potato tips, the amount of the tea leaves is 8.5 parts by weight, the amount of sweet potato tips is 1.5 parts by weight, the total is 10 parts by weight; each part is 1000 grams.

[0042] The described formula oolong tea is prepared in sequence as follows: (1) Withering: Dissipate part of the water in the tea leaves and sweet potato tips through withering, so that the water content in the tea leaves and sweet potato tips is 12-15%, and improve leaf toughness;

[0043] (2) Greening: the withered tea leaves are placed in a green shaker and shaken, the leaves collide with each other and scratch the edge cells of the leaves, thereby promoting enzymatic oxidation. After shaking, the leaves change from soft to hard, and then stand for a while , The oxidation is relatively slowed down, so that the water in the petiole veins slowly diffuses to the leaves. At this time, the fresh leaves...

Embodiment 2

[0048] The semi-fermented formula oolong tea with potato tips for tea is composed of tea leaves and sweet potato tips, the amount of the tea leaves is 5 parts by weight, the amount of sweet potato tips is 5 parts by weight, the total is 10 parts by weight; each part is 1000 grams.

[0049] The preparation method is the same as in Example 1.

Embodiment 3

[0051] The semi-fermented formula oolong tea with potato tip for tea is composed of tea leaves and sweet potato tips, the amount of the tea leaves is 6 parts by weight, the amount of sweet potato tips is 4 parts by weight, the total is 10 parts by weight; each part is 1000 grams.

[0052] The preparation method is the same as in Example 1.

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.

Description

Technical field [0001] The invention relates to the field of tea preparation methods, more specifically it is a formula oolong tea prepared by combined semi-fermentation of tea leaves and potato tips. Background technique [0002] In my country, tea is generally divided into six types: (1) Green tea is a tea made without fermentation. It is named because its leaves and soup are green. (2) Black tea is a tea made through full fermentation. It is named because its leaves and soup are red. (3) Scented tea is one of the finished green teas. The fragrant flowers are scented in the tea embryo. (4) Oolong tea (a kind of green tea) is a semi-fermented tea, which is characterized by green leaves at the center and red edges, commonly known as green leaves with red borders. It has the mellowness of black tea, and it has a stronger astringency than ordinary black tea; it has the refreshing taste of green tea, its aroma is strong and lasting, and it leaves after drinking. (5) White tea ...
