Processing method of yellow loosestrife tea

Abstract

The invention discloses a processing method of yellow loosestrife tea. The processing method of the yellow loosestrife tea includes the steps of A, collecting flowers, removing impurities, spreading for cooling; B, fixing, namely placing the flowers which are spread and cooled in a drum-type continuous fixation machine for fixation for 3-5 minutes at 200-300 DEG C; C, primarily drying, namely primarily drying the flowers of yellow loosestrife in a drying machine at 50-60 DEG C for 3-5 minutes with 20%-35% water content controlled; D, deodorizing, namely placing the flowers of yellow loosestrife which are primarily dried in a steamer, and steaming the flowers with steam for 3-5 minutes; E, seasoning, namely making 0.1%-1% aqueous solution of stevioside, and evenly spraying the aqueous solution to the deodorized flowers of yellow loosestrife; F, redrying, namely placing the seasoned flowers of yellow loosestrife in the drying machine, drying the flowers with 50-60 DEG C hot air for 45-60 minutes, and discharging, packaging and sealing to obtain the finished product when water content is lower than 13%. The processing method is reasonable in design. The flowers of yellow loosestrife never cake and have few dregs during processing. Operation is simple, and equipment is simple. The processing method is easy to popularize and has evident social and economic benefits.

Description

technical field [0001] The invention relates to a processing method of tea, in particular to a processing method of coptis flower tea. Background technique [0002] Coptis chinensis is derived from the incompletely opened flowers of Coptis chinensis Franch. Coptidis scape 1-2, 20-30cm high, with round hammer-shaped cymes on the top, each inflorescence has 5-9 small flowers, the total capsule is usually 3, lanceolate, 3-5 pinnately parted, The base is wide, the bracteoles are round and slightly smaller, the sepals are 5 yellow-green and narrowly ovate, 9-13cm long, 2-3cm wide, the petals are small, linear-lanceolate, 5-7mm long, there is a honey groove in the center, stamens Most, outer stamens slightly shorter or nearly as long as petals, free carpels 8-12, with short stalks. Studies have shown that Coptis chinensis is rich in protein and mineral elements and alkaloid components similar to Coptis chinensis, and has the function of lowering blood sugar and blood fat.

Problems solved by technology

Since the moisture content of fresh Coptis chinensis is as high as 90%, it is easy to become "cake-like" and poor in color after being dried directly. At present, the sensory quality of Coptis chinensis generally suffers from poor sensory quality such as cake-like, burnt, slag, and poor color in the processing process. Shortcomings
