Abstract
Fired tea are vacuum packed in aluminized bag of polyethylene or nylon. Vacuum packing can prevent tea from absorbing moisture and becoming oxidized. No nitrogen and other inert gas inflation can reduce cost. The aluminized polyethylene or nylon bag can isolate heat and sun and prevent tea from changing color. The packing method has one guarantee period as long as 12 months at 30 deg.c.
Description
The present invention is a kind of packing method that is used for tealeaves, especially for the packing method that improves the tea fresh keeping degree.
Mostly present packaging of tea is to carry out selling after the packing with plastic bag or kraft paper bag after product tea ground carries out fresh blade frying processing.But deposit after a period of time because the effect of moisture and oxygen, tealeaves oxidation and flavescence gradually, its freshness reduces.
In the existing patent application; a kind of packaging of tea; number of patent application 91103805.1; be in packaging bag, to improve the tea fresh keeping ability with the method that vacuumizes and add the unreactable gas of nitrogen and so on; but the method is manufactured with multilayer materials; not only require the quality height of packaging of tea; and owing to adopt big packaging bag; in case in the time of will using tealeaves; residue tealeaves still will be oxidized and reduce freshness. Chinese invention patent application " a kind of packing method of tealeaves "; number of patent application is 97109151.X, in open day on December 30th, 1998, is characterized in dozens of small package bag tealeaves is put into big packaging bag; extracting vacuum and sealing are carried out in big packaging bag; tealeaves in the small package bag is under the protection of two-layer vacuum, thereby can prevents humidity and oxidation, make the tea fresh keeping in each small package bag.Its shortcoming is that it adopts the common plastics packaging bag, and when temperature is in more than 30 ℃, after after a while, the easy flavescence of tealeaves can not be played heat insulation, sun-proof effect, and fresh-keeping effect is relatively poor, and owing to adopt the double-deck mode that vacuumizes, the tea packaging cost increases.
The purpose of this invention is to provide a kind of tealeaves freshness, sun-proof, antifade, vacuum tea packing method with aluminized bag that cost is low of keeping in a long time.
The object of the present invention is achieved like this: a kind of vacuum tea packing method with aluminized bag, tealeaves after the frying processing is divided in the packaging bag, the packaging bag extracting vacuum is sealed, packaging bag is an aluminizing packaging bag, packaging bag pressure is 8-10 barometric pressure, and bag material adopts 0.6-0.8ppm polyethylene or nylon.
Because the present invention adopts the mode vacuumize, can prevent the tealeaves moisture absorption and oxidation, improve the freshness of tealeaves, and wherein do not charge into unreactable gas such as nitrogen, cost is lower.Because aluminium plating polyethylene or nylon bag pack are adopted in packaging bag, play heat insulation, sun-proof effect, make the constant color of tealeaves.Because this packing can adopt large and small multiple manner of packing, has economical and practical characteristics.This manner of packing not only technology is simple, and cost of manufacture is low, and moistureproof, anti-oxidation, sun-proof performance is good, and under air tight and 30 ℃ temperature, storage period is 12 months, and the tea fresh keeping phase is long.
Below in conjunction with embodiment the present invention is further described.
Dried tea is processed in tealeaves harvesting before clear and bright, was installed with 0.6ppm polyethylene or nylon film aluminizing packaging bag in 24 hours, with the encapsulation of vacuum automatic-packaging, the packaging bag internal pressure is a 8-10 barometric pressure.Tealeaves can make fragrance, mass dryness fraction, shape invariance by vacuum-packed, reaches fresh-keeping effect, and aluminizing mainly is anti-solar radiation, and heat-insulation and heat-preservation makes tealeaves color in 12 months constant, keeps Normal juice source flavor.
By test, this packing method listing is when the 6-12 month sells then, and every kilogram of tealeaves price can improve 7.5 yuans, has improved economic benefit greatly.
