Abstract
The present invention relates to a preservation agent for pure natural tea and a preservation method thereof. Wild plants rich in polyhydric compounds and wild plants rich in compounds with multiple units of crystallization water are mixed and made into granules according to a certain proportion, and then the preservation agent is obtained. The preservation agent is subpackaged with ventilation materials, and the preservation agent and tea leaves are loaded into light-tight and air-tight packaging bags of compound films, sealed and stored; the preservation agent has the advantages of no toxicity, no foreign taste, simple technology and low cost, no special devices are needed, and the shelf life can be more than 1 year.
Description
The present invention relates to a kind of is the pure natural tea antistaling agent and the tea fresh keeping method thereof of feedstock production with the wild plant.
China is Tea Production and consumption big country, spring tea accounts for the overwhelming majority of tealeaves gross output, yet the not anti-storage of tealeaves, quality deterioration very easily takes place, make the progressively good color quality of its forfeiture of tealeaves, produce painful ageing flavor, and along with the resting period is of a specified duration more, this bad realization resembles serious more.The principal element that causes the bad change of tea leaf quality is the humidity of storage environment, airborne oxygen, light and temperature.The existing deepfreeze of tealeaves storage fresh-keeping, bleed fill nitrogen, vacuum packaging, with methods such as oxygen scavenging chemical and chemical hygroscopic agent, be the measure of taking at the factor that causes the bad change of tealeaves aspect separately, and need Special Equipment to make cost too high, or use chemical substance and difficultly accepted by the consumer, there are not a kind of desirable tealeaves storage fresh-keeping technical measures up to now.
The objective of the invention is to overcome the deficiency of prior art measure, provide that a kind of with low cost, method is simple, good refreshing effect, the tea antistaling agent of the nontoxic free from extraneous odour of pure natural and supporting preservation method thereof.
Content of the present invention is to be raw material with several wild plants, is mixed with antistaling agent by a certain percentage through pulverizing, and fully wraps into venting bags after the drying and puts into airtight, lighttight packaging bag sealing with tealeaves and store.
The present invention is achieved in that (1) is raw materials used for being rich in Diospyros, Castanea and the oak plant of compound of polyhydroxy and multi-crystallization water, utilize compound to lose the hygroscopicity behind the crystallization water and the easily oxidizable of polyol, reach the purpose of moisture absorption deoxygenation; (2) leaf of above-mentioned 1～2 kind of plant is pulverized, with the hot water leaching of about 50 ℃ of 5～10 times of amounts, two plants are got its shell and the oven dry of oak skin, are crushed to 20 orders in addition, mix in the ratio that respectively accounts for 15%～75%, soak with extract; (3) 180～200 ℃ of dryings of mixture after the immersion are made a type antistaling agent, are distributed into pouch with ventilative paper bag; (4) tealeaves to be stored airtight, the lighttight composite film packaging bag of packing into adds 2% packed antistaling agent sealing, In Shade storage.
The invention has the advantages that:
1. antistaling agent is an All Pure Nature wild plant feedstock production, does not introduce any chemicals in the production overall process, meets the organic food production requirement.
2. do not influence growth and development of plants after the used plant material collection, do not destroy ecological environment, meet environmental protection requirement.
3. antistaling agent has moisture absorption deoxygenation dual-use function, does not contain any toxic substance, and nontoxic free from extraneous odour does not have a negative impact to tea leaf quality because of tealeaves has strong suction-operated, the fresh-keeping effect ideal, and the shelf-life can reach more than 1 year.
4. raw material extensively are easy to get, and production technology is simple, and the production and the preservation process of antistaling agent need not special installation, and be with low cost, and family, enterprise all can use.
Claims (2)
1. pure natural tea antistaling agent, it is characterized in that leaf, shell and the oak skin of Diospyros, Castanea and oak plant with the compound that is rich in polyhydroxy and multi-crystallization water is raw material, the shell of pulverizing and oak skin mix in 15%～75% ratio and soak afterwards with the persimmon leaf extract that drying forms.
2. with the supporting tealeaves method for storing and refreshing of claim 1, it is characterized in that sealing storage with airtight, lighttight composite film packaging bag in the lump with treating fresh-keeping tealeaves after the antistaling agent that claim 1 is prepared is used ventilative paper bag packing.
