Description
[technical field]
The present invention relates to Tea Processing technical field, the processing method being specifically related to a kind of leaf of Camellia nitidissima Chi.
[background technology]
JINHUA Camellia Theaceae, flower is golden yellow, has high ornamental value and medical value.Leaf be processed to tea or
Person's beverage, has high nutritive value and medical value.Camellia nitidissima Chi contains 400 multiple nutrients materials and has no side effect, right
Diabetes and complication thereof are had unique magical effect, have cancer-resisting by blood sugar lowering, lowering blood pressure and blood fat, cholesterol reducing
Effect.
The Major Nutrient material of tea is present in intracellular, and the cell wall of cell surface layer and cell membrane are by these nutrient substance bags
It is trapped among intracellular, to ensure the normal metabolic activity of cell.Tea Processing mainly by destroying cell surface layer structure, makes cell
Interior material flows out and is attached on Folium Camelliae sinensis, is easier to be dissolved in water when brewing tea, thus improves the concentration of millet paste.
The mouthfeel of millet paste is had a significant impact by tea Processing method, and in order to improve the quality of Folium Camelliae sinensis, people explore different
Processing method.Traditional tea processing is main, and by kneading destruction cell wall, the method is low to the destruction efficiency comparison of cell wall, and
The course of processing expends muscle power, and it is bigger to millet paste taste-affect that difference kneads mode；Also cellulase and pectase degraded are utilized
The method of cell wall, however it is necessary that Acidity of Aikalinity and the temperature etc. controlling reaction condition, and reacts slow.
High voltage pulse electric field processing can effectively destroy membrane structure, improves cell permeability, and its principle is that cell exists
Can regard an electrolyte in electric field as, under high voltage electric field effect, cell membrane is breakdown, produces the destruction of unrepairable, has
Sterilization, the effect of inhibitory enzyme activity, be widely used in the processed of biomaterial.
[summary of the invention]
It is an object of the invention to: for the problem of above-mentioned existence, it is provided that a kind of Camellia nitidissima Chi processing method, the present invention is at tea
Leaf processing early stage utilizes high-pressure pulse electric that Folium Camelliae sinensis carries out pretreatment, changes membrane passage, improves Folium Camelliae sinensis intracellular
Substance release ability, when being beneficial to knead, tea juice is fully extruded and is attached to Folium Camelliae sinensis surface, reach quick-drying purpose simultaneously；To tea
Leaf surface sprays light salt brine, has certain sterilization, inhibitory enzyme Fermentation, can slow down Folium Camelliae sinensis and add during processed
The oxidation of tea polyphenols during work, its tea flavour of the Folium Camelliae sinensis of preparation is mellow and has promoting the production of body fluid to quench thirst effect.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of processing method of Camellia nitidissima Chi, its step includes:
(1) pluck: pluck Camellia nitidissima Chi tender leaf；
(2) cleaning is dried: is immersed in water after 10-20 minute by fresh tender leaf, rinses 2 times, uniformly divides on bamboo is sieved
Dry；
(3) pretreatment: Folium Camelliae sinensis is placed in high-pressure pulse electric and adjusts electric pulse field parameter Folium Camelliae sinensis is carried out pretreatment, described
Electric pulse field parameter includes: electric field intensity 10-60KV/cm, frequency 10-100Hz, pulse width 1-50 μ s；
(4) saline is sprayed: uniformly spray saline on Folium Camelliae sinensis surface；
(5) complete: Folium Camelliae sinensis is evenly laid out on pallet, complete in the baking oven of 200-230 DEG C 15-30 minute；
(6) knead: Folium Camelliae sinensis is placed on pallet, rub back and forth in 60-80 DEG C of baking oven and grab sth. made by twisting and make Folium Camelliae sinensis be wound into bar, tea juice
Fully overflowing and be attached to Folium Camelliae sinensis surface, its moisture content is 15-20%；
(7) baking: by evenly laid out for Folium Camelliae sinensis on pallet, puts in baking oven and toasts, and baking temperature is 100-120 DEG C, dries
The roasting time is 1-2 hour.
Preferably, described electric pulse field parameter includes: electric field intensity 20-40KV/cm, frequency 50-80Hz, pulse width 1-10 μ
s。
In described pretreatment, every kilogram of Folium Camelliae sinensis is repeated high voltage pulse electric field processing 2-5 time, it is ensured that cell membrane is the most broken
Bad.
Described sprinkling saline treatment is that every kilogram of Folium Camelliae sinensis sprays saline 150-200 gram；Described saline be sodium chloride with go from
The mixed solution of sub-water, its concentration is 0.3-0.5%；Saline has the effect of sterilization, inhibitory enzyme activity, can slow down Folium Camelliae sinensis and add
The oxidation of tea polyphenols during work.
After the described process that completes, water loss rate of tea leaves is 30-40%, it is ensured that Folium Camelliae sinensis fully softens, and is beneficial to knead and avoids simultaneously
Folium Camelliae sinensis occurs fracture to affect outward appearance.
Preferably, described baking temperature is 100-110 DEG C, and baking time is 1-1.5 hour, has toasted rear Folium Camelliae sinensis aqueous
Rate is less than 6%, is the Camellia nitidissima Chi finished product of the present invention.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: in the present invention, owing to adding
Work early stage utilizes high-pressure pulse electric that Folium Camelliae sinensis carries out pretreatment, changes membrane passage, and when being beneficial to knead, tea juice is filled
Point extrusion is attached to Folium Camelliae sinensis surface, improve the dry rate of Folium Camelliae sinensis simultaneously；Folium Camelliae sinensis is sprayed light salt brine, saline and high-voltage pulse electric
Processing all has the effect of sterilization, inhibitory enzyme activity, can slow down the oxidation of tea polyphenols, the Folium Camelliae sinensis of preparation during Tea Processing
Remaining the primary colors of Folium Camelliae sinensis to greatest extent, its tea flavour is mellow and has the effect of promoting the production of body fluid to quench thirst.
