Problems solved by technology

Now the processing technology of black tea is more traditional, such as application number CN201611228578.8 "A Method for Making Black Tea", application number CN201610329158.2 "A Method for Making Black Tea", application number 201611012185.3 "A Method for Making Black Tea" "Fafa", etc., the beneficial ingredients of black tea produced: such as free amino acids, carotene, vitamin A, caffeine, water-soluble total sugars, flavonoids, tea polyphenols, theaflavins, thearubigins, theabrownins, catechins The tea element and so on did not improve
Therefore, the color, aroma, taste and nutritional value of black tea are difficult to meet the needs of consumers.

Abstract

The invention belongs to the technical field of tea beverages, and particularly relates to a making method of black tea. The making method comprises the following steps of performing sorting, performing withering, performing rolling, performing fermentation, and performing drying. Through special withering treatment, the breakage rate of cells of tea leaves is increased, so that more substances in mesophyll cells during fermentation can be oxidized, accumulation of beneficial components is facilitated, and beneficial components such as water extractions, amino acids, caffeine, flavone, soluble sugar, theaflavin, thearubigins, theabrownin and catechin are all increased, the nutrient value of the black tea is increased, and the mouth feel of the black tea is improved. The black tea prepared by the method disclosed by the invention is red bright in soup color, pure in fragrance, and sweet and pure in taste and has fragrance of flowers.

Description

technical field [0001] The invention belongs to the field of tea beverages, in particular to a method for making black tea. Background technique [0002] As the earliest country in the world to process and drink black tea, my country has recorded records on black tea processing as early as the early Ming Dynasty, such as "blue paste black tea" and "crispy sign black tea" and other records about black tea production are recorded in Liu Ji's " In the book "Multiple Energy and Despicable Things". In recent years, black tea can effectively balance the intestinal flora (Xu Jingyi, Cui Xiudan, Chen Changhui, etc. Research on the antibacterial effect of six major teas on some intestinal pathogenic bacteria[J]. Food Industry Science and Technology, 2013, 34(16): 140-142.), lipid-lowering, anti-oxidation, and anti-cancer effects are gradually becoming clear. With the enhancement of people's awareness of health care, black tea is favored by more and more consumers for its unique quali...
