Abstract

The invention relates to a new green tea processing method. The new green tea processing method comprises the following steps: selecting fresh violet tea leaves which are complete in bud leaves, are uniform and consonant in sizes, are not crushed into pieces and are free from diseases and insects as processed objects; performing vacuum blanching treatment on the picked tea leaves for 1 minute at the temperature of 60-65 DEG C; putting the tea leaves after heat treatment in a clean dry bamboo strip disk until the moderate moisture content of the tea leaves is 70-72%, controlling the indoor temperature to be 18-22 DEG C so that the leaves are not mutually adhered, and unceasingly turning the tea leaves in the process of drying the tea leaves so as to avoid the phenomenon that the tea leaves are accumulated together to be fermented; putting the dried tea leaves into refrigeration equipment, and performing refrigeration under the temperature of -2 DEG C for 20-30 minutes; placing the refrigerated tea leaves into a low-temperature cold air drying machine, wherein the temperature of cold air is 5-10 DEG C, and when the moisture content of the treated tea leaves achieves 15-20%, taking out the treated tea leaves; packaging the tea leaves which are dried at the low temperature under vacuum environment, charging nitrogen gas for keeping the tea leaves fresh, performing sterilization at the temperature of 121 DEG C for 20-25 minutes, and putting finished products in a refrigerating chamber for storage.

Description

A kind of Green Tea Processing new method
Technical field
The present invention relates to tea making technology field, be specifically related to a kind of Green Tea Processing new method.
Background technology
Drinking tea is the tea culture of Chinese tradition, and tealeaves has all multi items such as black tea, green tea, oolong tea, jasmine tea at present, and due to the difference on raw material and processing method, its grade has very large difference.Green tea belongs to azymous local tea variety, and its Tea Polyphenols degree of oxidation is zero or close to zero.Although green tea natural shape, simple and elegant fresh refreshing, dark liking by some crowds.The frying mode of centuries tealeaves be all by completing, kneading, the technique such as oven dry carries out, mode of operation depends on the experience of frying tea master worker, the bad unification of quality, and original local flavor also scatters and disappears in each processing step.
Summary of the invention
It is simple, good in economic efficiency that technical problem to be solved by this invention is to provide a kind of method, is applicable to the Green Tea Processing new method of batch production.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of Green Tea Processing new method, it is characterized in that, processing step is as follows:
1) select bud-leaf complete, size uniformity, does not freshly crush, and the fresh picking leaves of anosis worm leaf, purple leaf, as processing object, puts into clear water or cleaning solution cleans up, and it is stand-by to drain the water;
2) to step 1) in pluck tealeaves carry out vacuum blanching process, vacuum blanching temperature at 60-65 DEG C, vacuum blanching process 1 minute; Temperature is too high easily to be cooked by scalding tealeaves, does not too lowly reach blanching object;
Traditional tealeaves mainly adopts the mode of completing to carry out preliminary treatment, affects tea color, also easily causes damage to tealeaves; The present invention adopts and heat-treats under vacuum conditions, reduces tealeaves surface-active, can not variable color after making it contact with air;
3) by step 2) in tealeaves after heat treatment be placed in clean, dry thin bamboo strip dish, thickness 2-3 centimetre, generally spread 2-4 hour, wait for that moisture is appropriateness when 70-72%, indoor temperature controls at 18-22 DEG C, make mutual adhesion between blade, constantly stir in dry process, avoid being deposited in cause together tealeaves produce fermentation phenomenon;
4) by step 3) in dry after tealeaves put into freezing equipment, carry out freezing at the temperature of-2 DEG C, cooling time is 20-30 minute; Object guarantees the freshness of tealeaves, reduces the evaporation of active ingredient and the oxidation of blade, nutriment of remaining valid to greatest extent;
5) by step 4) in freezing after tealeaves be placed in low-temperature cold wind drying machine, cold wind temperature 5-10 DEG C, process and take out when tealeaves divides and reaches 15-20%;
Employing low-temperature cold wind is dry, and can prevent tealeaves surface oxidation from producing free radical and bad flavor largely, it is to allow tealeaves have good mouthfeel and local flavor when drinking that the moisture of tealeaves controls in this scope of 15-20%;
6) by step 5) in tealeaves after low temperature drying pack under vacuum conditions, and inflated with nitrogen is fresh-keeping, then through 121 DEG C of sterilizing 20-25 minute, enters freezer storage.
Above-mentioned cleaning solution is made up of the component of following parts by weight: mountain spring water 100 parts, modified corn starch 5 parts, garlic juice 2 parts, ginger juice 2 parts, the xylitol aqueous solution 2 parts, soda ash 5 parts, honeysuckle flower water extract 2 parts, citric acid 0.5 part, salt 0.1 part, white wine 0.5 part, vitamin C 0.05 part, soybean protein isolate 1 part; Sterilization, sterilization can be played for cleaning tealeaves, going deimpurity object.
The invention has the beneficial effects as follows: the inventive method is simple, practical, according to the tealeaves that this technique makes, bright-colored, retain the original local flavor of tealeaves, reduce the stimulation to human intestines and stomach after drinking simultaneously, improve tealeaves total quality, improve the market competitiveness, to the continuing of Tea Production, stablize, develop in a healthy way significant.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the present invention further.
