Abstract
The invention relates to an air-controlled freshness protection bag for storing young garlic shoots and the application thereof. The freshness protection bag with a thickness of 30-60 micrometers is made of a polyethylene film or a polyvinyl chloride film, and the specification is that bag width is 50-80 centimeters, and bag length is 100-130 centimeters. The film has 1-30 tiny pores with a pore diameter of 0.01-1.0 millimeters. 15-30 kilograms of the young garlic shoots can be contained in the freshness protection bag, the tying of the bag is sealed, under the environment of -1.5-0 DEG C, the young garlic shoots can be kept fresh for more than 10 months, and good moss rate is more than 90%. During storage, the bag needs no opening for air or is opened less than 5 times. The pores with suitable pore diameter and amount are arranged on the polyethylene or polyvinyl chloride freshness protection bag, and accordingly, bag opening times can be reduced, bag-manufacturing cost can also be reduced, and the air-controlled freshness protection bag is of obvious advantage.
Description
Technical field
The invention belongs to the food preservative technology field, particularly a kind of garlic stems storage is with air-adjustable fresh-keeping bag and application thereof.
Technical background
Garlic stems is China's bulk vegetable, and yearly output is at 5～1,000,000,000 kilograms.Garlic stems is anti-storage vegetables, adopts suitable storage practice, can preserve more than 10 months.The garlic stems freshness protection package that uses at present is many to be made by polyvinyl chloride film, thickness 40～50 μ m.But the garlic stems freshness protection package Air permenbility that uses at present is on the low side, makes oxygen concentration too low (or gas concentration lwevel is too high) in freshness protection package.Thereby need frequently to open the bag venting in storage, and expend a large amount of manpowers, increase the cost of storage.In order to improve the permeability to air of garlic stems freshness protection package, people have offered silicon window (silicon window area 60～100 ㎝ on common garlic stems freshness protection package
2), obtained good effect, also be used widely on market at present.But offering the silicon window on each garlic stems freshness protection package increases the cost of garlic stems freshness protection package greatly.
Offer small pore and also can improve permeability to air on the garlic stems freshness protection package, have the effect similar to offering the silicon window.But the diameter of pore and quantity are the keys that affects the garlic stems storage effect.Too small or the quantity of hole diameter very little, permeability to air is inadequate, can not get the effect of preservation and freshness; The aperture is excessive or hole number is too much, and permeability to air is too high, also can not get the effect of preservation and freshness.Offer small pore on the garlic stems freshness protection package, and control aperture and hole number well, can make to keep suitable gas composition in the garlic stems freshness protection package, can obtain good fresh-keeping effect, reduce simultaneously the cost of storage.
Summary of the invention
The purpose of this invention is to provide a kind of garlic stems storage air-adjustable fresh-keeping bag and controlled atmosphere application engineering thereof.
For achieving the above object, the present invention is by the following technical solutions:
Air-adjustable fresh-keeping bag is used in a kind of garlic stems storage, and it is characterized in that: adopting preservative film is polyethylene or polyvinyl chloride film, thickness 30-60 μ m, bag width 50～80cm, length 100～130cm.The small pore of preparation on film, air vent aperture 0.01～1.0mm, 1～30 of pore quantity.
Adopt described garlic stems air-conditioning preservative film, be used for the controlled atmosphere of garlic stems, it is characterized in that: 15～30 kilograms of the in-built garlic stems of freshness protection package, fill sub-tying sealing, be placed under-1.5～0 ℃ of environment, duration of storage need not opened the bag venting or open bag below 5 times.Adopt the method that garlic stems was preserved more than 10 months, garlic stems tongue footpath is full, lovely luster, and excellent flavor, good tongue rate is more than 90%.
Compared with prior art, this method has clear superiority on the spontaneous controlled-atmosphere preservation of garlic stems.Existing garlic stems spontaneous controlled-atmosphere preservation film is mainly polyvinyl chloride film, thickness 40～50 μ m.Need frequently open bag venting (preserved 300 days, and opened bag more than 25 times) in storage, expend a large amount of manpowers.Adopt silicon window bag, can greatly reduce out a bag number of times, but the silicon window bag cost of manufacture is higher.Offer aperture, pore that hole number is suitable on polyvinylchloride or polyethylene freshness protection package, both can reduce out a bag number of times, also can reduce the bag cost, have clear superiority.
The specific embodiment
A kind of garlic stems storage air-adjustable fresh-keeping bag and application thereof comprise following content:
The spontaneous controlled-atmosphere preservation method of garlic stems, freshness protection package used is made by polyethylene or polyvinyl chloride film, film thickness 30-60 μ m, the sack specification is: bag width 50～80cm, length 100～130cm.Small pore is arranged, air vent aperture 0.01～1.0mm, 1～30 of pore quantity on film.15～30 kilograms of the in-built garlic stems of freshness protection package fill sub-tying sealing, are placed under-1.5～0 ℃ of environment, and duration of storage need not opened the bag venting or open bag below 5 times.Adopt the method storage garlic stems more than 10 months, good tongue rate is more than 90%.
Embodiment 1
Adopt polyethylene foil as preservative film, film thickness 50 μ m make the freshness protection package of 70 ㎝ * 120 ㎝, the small pore of preparation aperture 0.2 ㎜ on preservative film, 14 of hole number.With this freshness protection package packing 25kg garlic stems, tightened sack and be placed in the freezer of-0.8 ± 0.3 ℃ storage 300 days.Do not open the bag venting in storage.For comparing storage effect, adopt silicon window bag to do contrast, silicon window bag is placed in same freezer, manages by same mode.Preserve after 300 days, the equal tongue of the garlic stems of two kinds of packings footpath is full, and the tongue bud does not expand, and tongue is slightly normal.But the garlic stems tongue footpath in the micropore bag is more bud green, and micropore bag cost is lower than silicon window bag.
Embodiment 2
Adopt polyvinyl chloride film as preservative film, film thickness 45 μ m make the freshness protection package of 60 ㎝ * 115 ㎝, the small pore of preparation aperture 0.15 ㎜ on preservative film, 26 of hole number.With this freshness protection package packing 20kg garlic stems, tightened sack and be placed in the freezer of-0.8 ± 0.3 ℃ storage 300 days.Open bag venting 4 times in storage.For comparing storage effect, adopt common polyvinylchloride bag to do contrast.Two kinds of packaging bags are placed in same freezer, manage by same mode.Preserve after 300 days, the equal tongue of the garlic stems of two kinds of packings footpath is full, and the tongue bud does not expand, and tongue is slightly normal.But common bag is opened bag venting 32 times in storage, the cost of storage is higher than the micropore bag.
Embodiment 3
