[0004] CN106954690A discloses a method for preparing floral-flavored white tea, which includes the following steps: withering fresh leaves by sunlight, light shaking, indoor micro-scale control of withering, vibration wave greening, high-temperature initial drying, rolling while hot, drying, picking and re-picking The flower-flavored white tea is prepared by fire. The shape of the flower-flavored white tea prepared by the invention is slightly shrunken and the leaves are half-rolled. Complete and translucent, although it shortens the withering time of white tea and has a floral fragrance, the white tea it produces is bitter and tastes bad

Abstract

The invention discloses a preparation method of Xinyang white tea, comprising the following steps: (1) picking fresh leaves (2) withering for the first time (3) shaking green for the first time (4) withering for the second time (5) rolling for the first time (6) Shaking green for the second time (7) Kneading for the second time (8) Drying for the first time (9) Picking and picking (10) Drying for the second time. The preparation method of the present invention prolongs the withering time, so that the content of tea leaves undergoes sufficient physical and chemical changes. By shaking the green leaves twice, the edge cells of fresh leaves are properly destroyed, and the aroma and taste of the tea leaves are improved. The transformation of aroma precursors forms a unique aroma. The first shaking of the green tea can increase the activity of tea enzymes, which is conducive to the hydrolysis and conversion of soluble substances such as amino acids and sugars, and increases the freshness of tea leaves, making the tea taste better. The second shaking green promotes the transformation of aroma substances and further enhances the aroma.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a preparation method of Xinyang white tea. Background technique [0002] White tea is white according to the appearance of the finished tea, hence the name white tea. Tea polyphenols in white tea are natural antioxidants, which can improve immunity and protect the cardiovascular system. White tea contains active enzymes necessary for the human body, which can promote fat catabolism, effectively control insulin secretion, decompose excess sugar in the blood in the body, and promote blood sugar balance. In addition, people who often drink white tea in summer rarely suffer from heat stroke. This is because White tea contains a variety of amino acids, which have the effects of reducing fever, dispelling heat, and detoxifying. [0003] The traditional production process of white tea is relatively simple. The picked fresh leaves are thinly spread on a bamboo mat an...
