Embodiment 1

[0025] A tea compound extract is specifically prepared by the following method:

[0026] (1) According to the mass ratio of 6-10:1-3, take old-leaf tea leaves and tobacco leaves and place them in the withering tank respectively, and use hot air at 30-35 ° C to wither; the old-leaf tea leaves are withered to a moisture content of 60-70%; Wither until the water content is 30-40%; cool to room temperature after withering;

[0027] (2) Mix the withered and cooled old-leaf tea leaves and tobacco leaves, add starch with a mass of 0.5-1%, and mix to obtain a mixture A; 0.02w% of the composite bacterial solution A was mixed, and treated at 25-30 ° C for 6-8 hours to obtain a primary fermentation product;

[0028] (3) Put the primary fermented product into the kneading machine and gently knead it for 8-10 minutes, then add it to the ethanol solution for soaking for 3-5 minutes, take it out, use steam at 200-220°C for 20-30s, and then heat it at 50-60 drying at ℃ until the water conte...

Abstract

The invention belongs to the technical field of tea deep processing, in particular to a tea compound extract and its preparation and application. The tea compound extract is made by the following method: (1) place the old leaf tea and tobacco leaves in the withering tank to wither and cool; (2) mix the withered and cooled old leaf tea and tobacco leaves, add starch and lightly After kneading, add compound bacterial liquid A to process to obtain a primary fermented product; (3) lightly knead the primary fermented product again, add it to ethanol solution for soaking, remove it, and dry it after steam treatment to obtain a dried product; ( 4) Pulverize the dry matter, add trehalose lipid and compound bacterial solution B to treat, sterilize, and obtain a secondary fermentation product; (5) add 50% ethanol solution to the secondary fermentation product, stir and heat up to extract, filter, and Filter to obtain the extract; after concentration and drying, the tea compound extract is obtained. The tea compound extract prepared by the invention has the characteristics of high biological activity, strong stability and good antiseptic performance.

Description

technical field [0001] The invention belongs to the technical field of tea deep processing, in particular to a tea compound extract and application. Background technique [0002] Tea is the buds and leaves of Camellia sinensis L., which has unique nutritional value and health care functions. The medicinal effects of tea were recorded in detail in the "Shen Nong's Materia Medica" of the Eastern Han Dynasty and the "Compendium of Materia Medica" of the Ming Dynasty. Modern medical research shows that tea contains a variety of active ingredients such as tea polyphenols, tea polysaccharides, alkaloids, vitamins, minerals, trace elements, etc., of which tea polyphenols are one of the main components of tea with health care functions. Tea polyphenols have the functions of scavenging free radicals, anti-oxidation, anti-aging, anti-cancer, anti-radiation, lowering blood fat and cholesterol, anti-atherosclerosis and antibacterial. Among them, tea polyphenols have certain antibacteri...
