Fermented deastringent coptis flower tea and preparation method thereof

Abstract

The invention discloses a fermented astringency-removed lysimachia davurica tea and a preparation method thereof. The fermented astringency-removed lysimachia davurica tea is composed of lysimachia davurica, cellulase, sodium chloride and lactic acid bacteria in certain proportion, and prepared through the steps of (1) picking lysimachia davurica in the flower bud period, washing the lysimachia davurica by using clear water, loosely spreading the lysimachia davurica in a bamboo steamer, putting the bamboo steamer in a steam cooker, timing under the condition of steam pressure, and spreading the lysimachia davurica for cooling; (2) in parts by the weight of the lysimachia davurica, adding the cellulase and carrying out enzymolysis; (3) taking the lysimachia davurica subjected to enzymolysis in the step (2), adding the sodium chloride in parts by the weight of the lysimachia davurica, fully and uniformly stirring, adding the lactic acid bacteria in parts by weight, uniformly stirring again, placing into an airtight container and carrying out oxygen isolated fermentation; and (4) after the fermentation is completed, drying, sterilizing and packing so as to obtain the lysimachia davurica tea. The astringency of the lysimachia davurica tea is obviously decreased, the lysimachia davurica tea is strong in reconstitution properties, flower-scented, and mellow in taste, and retains the original flower fragrance of lysimachia davurica, thereby improving the organoleptic quality and flavor of the lysimachia davurica tea.
