Problems solved by technology

Now the processing technology of black tea is relatively traditional, and the beneficial components of black tea produced: such as free amino acids, carotene, vitamin A, caffeine, water-soluble total sugar, flavonoids, tea polyphenols, theaflavins, thearubigins, Theabrownin, catechin, etc. did not increase
Therefore black tea soup color, aroma, taste and nutritional value are difficult to meet the needs of consumers.

Abstract

The invention belongs to the technical field of tea drinks and in particular relates to a processing method of black tea. The processing method of the black tea comprises the following steps: sorting, withering, carrying out freeze drying, mixing, rolling, fermenting and drying. The processing method of the black tea has the beneficial effects that the prepared black tea adopts a special processing technology, so that mesophyll cells of tea leaves are ruptured in a relatively mild state, various enzymes in cytoplasm and ingredients in solution 1 are fully contacted, all kinds of biochemical reactions in foliar cells are promoted, synthesis of aroma substances is promoted, aroma of the processed black tea is greatly improved, flowery flavor is strong, tea soup is bright red, taste is sweet and mellow, the highest amino acid content in the tea soup can reach up to 3.25%, theaflavin content can reach up to 0.30%, and aqueous extract content can reach up to 40.14%.

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...
