Abstract

The invention discloses a preparation technique for liquorice root black tea. The preparation technique comprises the following steps of fresh leaf picking, withering, two-step-method rolling, fermenting and microwave drying; dried tea and liquorice root extracting solution mixing through ultrasonic spraying, primary spraying, spread airing, drying, secondary spraying, drying, spread airing and drying, wherein during primary spraying, 50-70 ml of liquorice root extracting solution is used per gram of tea, during secondary spraying, 30-50 ml of liquorice root extracting solution is used for per gram of tea, and the temperature is kept within the range from 35 DEG C to 40 DEG C during spraying. After the prepared liquorice root black tea is brewed tea flavor is sweet, aftertaste is long, and the liquorice root black tea has the effects of enriching the blood, nourishing the stomach, clearing away heat and toxic materials, expelling phlegm to arrest coughing and treating stomach duct and abdomen.

Description

technical field [0001] The invention relates to the field of tea production, in particular to a production process of licorice black tea. Background technique [0002] Black tea is made from the new shoots and leaves of tea trees suitable for making this product, and is refined through typical processes such as withering, rolling, fermentation, and drying. Because of its dry tea color and the brewed tea soup is mainly red, it is named black tea. During the processing of black tea, a chemical reaction centered on the oxidation of tea polyphenols occurred, and the chemical components in the fresh leaves changed greatly. The tea polyphenols were reduced by more than 90%, and new components such as theaflavins and thearubigins were produced. . Aroma substances increased from more than 50 kinds in fresh leaves to more than 300 kinds, including caffeine. Catechin and theaflavins form a delicious complex, thus forming the quality characteristics of black tea, red soup, red leave...
