Problems solved by technology

However, due to the fact that the bitter taste cannot be removed or alleviated, especially because of the short shelf life, it has not been commercialized, and industrial production is blank, and a large amount of Polygonum multiflorum stems and leaves are wasted in vain.
Existing people process it into vegetables for consumption, but its taste is not acceptable to all people, so the market is limited

Abstract

The invention relates to a preparation method of polygonum multiflorum black tea. The method comprises the steps of leaf picking and cleaning, spreading for cooling, withering, roasting, rolling, temperature-controlled fermenting, drying for shaping, screening and finishing, packaging and the like. According to the polygonum multiflorum black tea prepared through the method, polygonum multiflorum belongs to traditional Chinese medicine, tender stems and leaves of polygonum multiflorum are fully fermented and cured, and therefore the tender stems and leaves not only have the corresponding nutritive value of polygonum multiflorum and the mellower mouthfeel, but also are free of additives, toxic and side effects and dependency and capable of being easily accepted by people after being prepared into the tea; due to the fact that the stems and leaves of polygonum multiflorum are very thin, fragile and not easy to shape, the tender stems and leaves are softer and rich in elasticity by adopting the method through the processes of spreading for cooling, withering, roasting, rolling, temperature-controlled fermenting and drying for shaping, and therefore the product can be shaped completely; the medicine fishy smell can be removed through temperature-controlled drying, and therefore the mouthfeel and the tea can be better. According to the preparation method of the polygonum multiflorum black tea, the medicine-tea dual-purpose effects are achieved, and meanwhile the planting benefit of polygonum multiflorum is improved, so that the whole plant can be developed and utilized; accordingly, the economic value of polygonum multiflorum is greatly improved.
