Abstract
The invention discloses the methods for increasing by one layer of preservative film on packaging material and articles.Using cyclopropylene as active constituent, with encapsulation agent or adsorbent, by the cyclopropylene of encapsulating or absorption, in the ratio of 1%-10%, it is added in the high molecular material that can be dissolved in dehydrated alcohol or organic solvent, stirs evenly and liquid is made, direct spraying or brushing is on packaging material and articles, one layer of preservative film is formed, makes packaging material and articles that there is fresh-keeping function.Present invention process is simply scientific, the gas of 1-MCP and does not suffer a loss.The Perserving materials are more stable in dry conditions, can save the long period.When encountering humid air, 1-MCP, which will be slow, to be released, fresh-keeping to the progress of fruits and vegetables flowers, and effect is reliable, using convenient.
Description
Technical field
The present invention relates to fruits and vegetables flower freshness packaging material fields.
Background technique
China is fruit and vegetable big producer, and more than 800,000,000 ten thousand tons of annual output, China's fruits output and area are sure to occupy always the world
First place, but China's preserving fruit and vegetable utilizing technology of storage and transport it is backward, caused by rot the proportion of goods damageds it is higher, fruit reaches 30%, and vegetables reach
30%-40% causes huge economic loss.And the proportion of goods damageds of developed country are then less than 7%.It is protected after fruits and vegetables harvesting in addition to improving
Except fresh storing technology, the transportation and packaging of fruits and vegetables also shows particularly significant, and especially fresh-keeping packaging more shows its importance.
1- methyl cyclopropene (1-MCP) can be used for the fresh-keeping of fruits and vegetables flowers, can delay fruit maturation, aging well, very
Hardness, the brittleness of product are kept well, are kept color, flavor, fragrance and nutritional ingredient, can be effectively kept the disease-resistant of plant
Property, mitigate and physiological disease is rotted and mitigated caused by microorganism, and moisture evaporation can be reduced, prevent from wilting.Use 1- methyl ring
The fresh-keeping product of propylene, freshness date can greatly extend.But 1- methyl cyclopropene is very active gas, highly volatile dissipates
It loses, especially in wet environment, 1- methylcyclopropene gas is easier to scatter and disappear.
It keeps fresh to extend the shelf-life of fruits and vegetables flowers product, inhibits the generation of plant endogenous ethylene as far as possible simultaneously
Prevent it from playing a role.1- methyl cyclopropene (1-MCP) is then best inhibitor.It was developed both at home and abroad around 1-MCP in recent years
Many fruits and vegetables flower freshness packaging materials and articles.Have plenty of 1-MCP thermoplastic into coating, the mixture containing 1-MCP
It is clipped in tunic, or 1-MCP is combined in adhesive layer with dry method, these preparation processes are more complicated.1-MCP is extremely
Active gas can make gas cause greater loss especially with thermoplastic processes.
Summary of the invention
The object of the present invention is to provide a kind of on packaging material and articles increases by the method for one layer of preservative film, can make to pack
Material and articles have fresh-keeping function.Preparation process of the present invention is simply scientific, can save the long period, moist empty when encountering
Gas, 1-MCP, which will be slow, to be released, fresh-keeping to the progress of fruits and vegetables flowers, and effect is reliable, using convenient.
The technical scheme is that increase the method for one layer of preservative film on packaging material and articles, it is characterized in that with
Cyclopropylene is added the cyclopropylene of encapsulating or absorption in the ratio of 1%-10% with encapsulation agent or adsorbent as active constituent
It is added in the high molecular material that can be dissolved in dehydrated alcohol or organic solvent, stirs evenly and liquid is made, direct spraying or brushing exist
On packaging material and articles, one layer of preservative film is formed, makes packaging material and articles that there is fresh-keeping function.
Wherein encapsulation agent includes: alpha-cyclodextrin, beta-cyclodextrin, gamma-cyclodextrin, mixing cyclodextrin and α-, β-, γ-ring
Dextrin derivative and Cucurbituril.
Wherein adsorbent includes: starch, dextrin, cellulose, silica gel, aluminium oxide, activated carbon, polyacrylamide, zeolite point
Son sieve, carbon molecular sieve and other organic and inorganic adsorbents.
The high molecular material of dehydrated alcohol or organic solvent can be wherein dissolved in, comprising: Lauxite, phenolic resin, shellac,
Rosin, alcohol-soluble nylon, hydroxypropyl cellulose, cellulose acetate, ethyl cellulose.
Wherein cyclopropylene is: 1- methyl cyclopropene, 1- pentyl-cyclopropene, 1- Octylcyclopropene.
Its packaging material includes: the low-density and density polyethylene film with high, polypropylene screen, polyvinyl chloride of plastic products class
Film and its polybag；Packing case, packing box made of paper product, wrapping paper, label, card, wrapping paper, filter paper, blotting paper, watt
Stupefied paper, paper washer, various numb paper, cotton paper, non-woven fabrics and other paper products.
This simple process science, the gas of 1-MCP and does not suffer a loss.The Perserving materials are relatively more steady in dry conditions
It is fixed, it can save the long period.When encountering humid air, 1-MCP, which will be slow, to be released, and fruits and vegetables flowers are carried out with fresh-keeping, effect
Fruit is reliable, using convenient.
According to our test, in the high molecular material described in this patent, encountering humid air can slowly release 1-MCP
Deflation body.Its rate of release are as follows: shellac > rosin > phenolic resin=Lauxite > alcohol soluble nylon > hydroxypropyl cellulose.
