The yellow tea loose tea of finished product is streak, and tealeaves only has outside the surface of 10% is exposed to, the surface of 90% is packed to as inner surface, and correspondingly, the dust on 90% tealeaves surface, worm's ovum, birds and beasts ight soil, agriculture is residual is wrapped in streak tealeaves.The present invention is when to raw tea material purified treatment, first that tealeaves humidification is saturated to absorbing water, and streak tealeaves is launched, makes the surface of tealeaves all become outer surface, thus for tealeaves surface contaminant stripping, remove and create conditions.
Heating using microwave is body heating, is heated inside and outside tealeaves simultaneously.Along with the applying of microwave, the moisture being absorbed into tealeaves inside during humidification is heated simultaneously and from inside to outside moves simultaneously, and the hydrone moving to tealeaves surface in a large number has then been actuated the pollutant stripping on tealeaves surface, come off.The degraded of agricultural chemicals is except utilizing except digestive enzyme degrades, also comprise thermal decomposition and volatilization, temperature is higher, thermal decomposition is more abundant, volatilization is then except temperature influence, the more important thing is that the reduction evaporation rate along with ambient pressure environment will be accelerated greatly, thus, vacuum environment and heating using microwave facilitate the degraded that tealeaves is surperficial and inner agriculture is residual greatly.Along with tealeaves Cell uptake microwave vibrations, heating, also promote pesticide molecule from the stripping tealeaves cell, the hydrone from inside to outside moved then achieves the product after by residual for agriculture molecule and degraded thereof from the inner transport to tealeaves surface of tealeaves, discharge simultaneously.Selection by winnowing, screening operation achieve the final removing to the pollutant come off from tealeaves surface.
Pesticide degradable enzyme is scientific research personnel is the Pesticide Residue solved on agricultural product and the biologic product developed specially, this kind of preparation comprise Beijing Schengenbiya Bioengineering Technology Co., Ltd. release than sub-pesticide degradable enzyme (being called for short than sub-enzyme), the Ma Dier pesticide degradable enzyme (being called for short Ma Dier enzyme) that Beijing ZTNH Enzyme Preparation Co., Ltd. releases, the pesticide degradable enzyme (in abbreviation section's enzyme) that Liaoning Zhongke Biological Engineering Co., Ltd. releases, the green core pesticide degradable enzyme (being called for short green core enzyme) that Beijing Jianong New Trading Development Co., Ltd. releases, etc.For than sub-enzyme, this digestive enzyme is organic phosphorus degrading enzyme, to pesticide molecule efficient degradation, and can not only can not cause secondary pollution to environment.
Previously, once someone utilized than sub-enzyme to purify tealeaves, or spray is shone on the fresh leaves of tea plant not yet plucked, or the green tea fresh leaves plucked for purifying object, especially the latter, adopt the long-time pesticide molecule soaking fresh interlobar part of degrading, outside, these purification styles not only production efficiency are low, lower than the utilization rate of sub-enzyme, and there will be similar " rain cyanines " phenomenon.Long-term tea making facts have proved, fresh leaf moisture content is too high, easily burntly when killing cyanines becomes, the tea product made, puckery and thin, and water colour is muddy.If fresh leaf, in purification run or handling process, makes fresh leaf be subject to some damages.This damage is that injured or broken or pressurized occur sultry, usually can play irrational fermentation before making, makes the dried-up or red stain of fresh leaf, is namely commonly referred to as " dead leaf ", affects tea-making quality very large.Make yellow tea, strictly should control fresh leaf by its technological requirement and gradually carry out " micro-fermentation " effect, if fresh leaf damaged, further process is with regard to difficulty very.Be event, wish to get the tea finished product that quality is good, the process of fresh leaf is needed very careful, exhaust one's ability, avoid " rain cyanines " phenomenon and " dead leaf " to produce.
The finished product loose tea of aqueous solvent to drying containing digestive enzyme is adopted to purify, because fresh leaf wax coat is destroyed, dry tea water imbibition increases, digestive enzyme can arrive each corner and the tealeaves inside on tealeaves surface fast, and under vacuum conditions, can not only discharge the gas of tealeaves adsorption, further accelerated solvent water soaking tealeaves, digestive enzyme obtains and fully, accurately utilizes.Therefore, with directly carry out compared with purified treatment to fresh tea leaf, the inventive method both avoided " rain cyanines " and fresh leaf damages the negative effect brought, in turn ensure that the production efficiency that tealeaves purifies, ensure that making full use of of digestive enzyme, and ensure that effective degraded of the inside and outside residual pesticide molecule of tealeaves.
Finished product loose tea has formed distinctive organoleptic quality, after dry tea absorbs water again, if run into suitable temperature again under aerobic state, further biological oxidation (being commonly called as " fermentation ") will occur in tealeaves, and changes the existing fragrance of the yellow tea of finished product, flavour.Therefore, in order to reduce this impact as far as possible, during humidification of the present invention, 1. controlling the addition of pure water, avoiding adding dilutional hyponatremia and causing tea juice to run off; 2. control tealeaves temperature, avoid or reduce tealeaves water suction its inside rear as far as possible the biochemical reactions such as non-enzymatic oxidation, microbial growth occur.Tealeaves to be humidified is placed in vacuum environment, and in vacuum environment, spray pure water or utilize atomization pure water to infiltrate, first vacuumizing and exhausting, rear infiltration, the effect that vacuumizes again can be produced, not only be conducive to the gas of discharging tealeaves absorption, and enable water immerse tealeaves inside fast, more easily infiltrate whole tealeaves, shorten humidification periods, reduce the biochemical reaction in tealeaves.In vacuum environment, humidification is with standing, reduces the oxygen content in environment, can suppress the further generation of the various biological oxidations of aerobic participation in tealeaves, is to keep the original quality of tealeaves to create necessary condition.
By the finished product loose tea humidification again of drying, the fragrance of tealeaves, flavour can be weakened.After tealeaves being carried out to selection by winnowing, screening, increase baking step, and impact in the temperature raising in short-term of curing process special secondary school door and arrange 60-80 DEG C, can excite tea aroma, strengthening tea flavour, makes the fragrance of tealeaves, flavour returns to the state before purification, even stronger.And after tealeaves moisture content≤8%, even if under the short time high temperature of 80 DEG C, also can not there is undesirable biochemical reaction and affect the quality of tealeaves in tealeaves inside.
