Abstract

The invention provides a novel aged golden-flower dark green tea processing technic, comprising the steps of taking aged tea of various tea leaves as raw material, carrying out humidification and germicidal treatment, adding Fuzhuan tea golden-flower fungus power to the obtained tea base, and then fermenting and cultivating, and drying after fermenting, thus obtaining the aged golden-flower dark green tea finished product. The novel aged golden-flower dark green tea processing technic provided by the invention, which is an import innovation of tea process technology, takes various aged teas as the raw material, fuses the key process of Fuzhuan tea, 'fungus growing', to reprocess, and obtains the aged golden-flower dark green tea through fermenting and drying; the obtained aged golden-flower dark green tea has the advantages that golden-flower is full, fungus potpourri is thick, taste is mellow and smooth, liquor color is bright, and the Fu tea quality flavor is obvious. The processing technic not only inherits part flavour characteristics of primary tea, simultaneously, the unique fungus potpourri caused by microbe fermenting is fused, a large variety of dark green tea products can be produced according to different raw material; meanwhile, aged tea and 'golden-flower' fungus are combined organically, the effective components of tea are converted through microbes, bioavailability is improved, and health care efficacy of tea is enhanced.

Description

technical field [0001] The invention belongs to the technical field of tea solid fermentation, and in particular relates to an aged tea golden flower dark tea and a processing technology thereof. Background technique [0002] Aged tea refers to various teas that have been collected and processed in the same year but not consumed in time and stored for a certain period of time, such as green tea, yellow tea, and oolong tea. With the increase of storage time, some acids, esters, alcohols, amino acids, vitamins and other effective functional components in tea are oxidized or condensed under the action of light, heat, water and gas, forming other water-insoluble Or volatile compounds change its fresh color, aroma and taste, and the original typical quality and flavor characteristics no longer exist. In daily life, tea leaves often lose their original tea properties due to improper storage, making consumers unwilling to drink them. Over time, new teas become old teas with low dr...
