Description

The preparation method of fermentation Folium Mori tea
Technical field
The present invention relates to processing field of tea leaves, be specifically related to the preparation method of a kind of Folium Mori tea of fermenting.
Background technology
Folium Mori are the dried leaves of moraceae plants Mulberry, are the conventional food of silkworm, have another name called a Mulberry, Jing Sang, Fructus Mori tree, yellow wood leaf Deng.It is cold in nature, sweet in the mouth, hardship, has effect of dispelling wind and heat pathogens, clearing away lung-heat and moistening for dryness, liver heat removing and eyesight improving, can treat anemopyretic cold, lung-heat type cough, Dizziness headache, conjunctival congestion is dim-sighted waits disease.
Along with the raising of people's living standard, tea-drinking is had higher requirement by people.Therefore Folium Mori tea has wide Market prospect.But, the dark brownish green taste of pure Folium Mori is dense, it is impossible to the people by frequent drinks green tea is accepted.In the way of natural fermentation The Folium Mori fermentation liquor color blackout produced, beany flavor weight, organoleptic quality is the best, and contain inside the Folium Mori tea after having fermented is thin Bacterium is more.
Summary of the invention
In view of this, it is an object of the present invention to provide the preparation method of a kind of Folium Mori tea of fermenting.The Folium Mori tea that the method prepares Organoleptic quality is good, and the Folium Mori tea interior detail bacterial content after having fermented is low.
To achieve these goals, technical scheme is as follows:
The preparation method of fermentation Folium Mori tea, comprises the following steps:
A. pretreatment: pluck Folium Mori when 5-8 in the morning and be soaked in water 15-18min clean, be placed in steamer and steam blue or green 25- 30s, then spreads and is cooled to room temperature;
B. knead: the Folium Mori through pretreatment are kneaded;
C. fermentation: carrying out aerobic fermentation in the Folium Mori through kneading are placed in fermenting cellar, fermentation time is 5-6h;
D. it is dried: step C gained fermentation afterproduct is dried.
Further, during spreading described in step A, thickness is 1.5-1.8cm.
Further, the degree kneaded described in step B is rolled twig rate >=85%, cell-damaging rate 48%-55%.
Further, described in step C, sweat microorganism used therefor is mixed by the raw material of following mass parts: acetobacter 4-7 part, cellulase 4-8 part, Aspergillus flavus 3-5 and Trichoderma spp. 2-4 part.
Further, described in step C, sweat microorganism used therefor is mixed by the raw material of following mass parts: acetobacter 5.4 parts, cellulase 6.3 parts, 4.5 parts of Aspergillus flavus and Trichoderma spp. 2.8 parts.
Further, the consumption of sweat microorganism described in step C is the 0.15%-through the Quality of Mulberry Leaves kneaded 0.18%.
Further, in sweat described in step C, basal fermentation liquid temp is 35-36 DEG C, control fermenting cellar temperature 28 DEG C- 30 DEG C, relative humidity 72%-78%, pressure inside the tank 0.018-0.023MPa of fermenting, it is passed through amount of oxygen 780-800m3/h.Described Basal fermentation liquid is the mixture that mix homogeneously not yet carries out fermenting.
Further, the degree dried described in step D is water content 4.5%-5.1%.
The invention has the beneficial effects as follows:
The Folium Mori tea granule tight knot of the present invention, intense excess syndrome, uniform, color profit, fragrant high, soup color glow, tender even glow at the bottom of leaf, fermentation Folium Mori tea interior detail bacterial content after completing is low.
