At present, tablet 1-MCP and liquid 1-MCP both domestic and external have preferable fresh-keeping effect, but there are still using not
The problems such as convenient, not easy to operate and unstable.1-MCP tablets need airtight condition and closed stifling 6- during practicing
12 hours, complex operation, it is not easy extensive quick storage；Liquid 1-MCP is in normal temperature condition stability inferior difference, it is necessary to be store in low temperature
Hide the stability that just can guarantee that 1-MCP.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of preservation and freshness applied to fruits and vegetables, easy to use, effect
Fruit is stable and is more easy to 1- methyl cyclopropene tin foils of popularization and application and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is：A kind of 1- methyl cyclopropenes tin foil, including original
Ply of paper and the fresh-keeping layer coated on body paper layer surface；The original paper layer mixes the system of copying by bamboo pulp and hardwood pulp, and original paper layer is determined
Measure as 120-150g/m2；The fresh-keeping layer includes 1- methyl cyclopropenes inclusion complex, polyethylene glycol PUR, water absorbing agent, dispersant
And sustained release agent, the quantification of 15-40g/m of fresh-keeping layer2。
When 1- methyl cyclopropene tin foils are added in the carton or container of fruit or vegetables, steam caused by fruits and vegetables breathing
The fresh-keeping paper and coating slow control release 1- methyl cyclopropenes (1-MCP) into container can be induced with carbon dioxide, and 1-MCP is
Ethylene blocking agent, fruits and vegetables can be suppressed and produce ethene, delay fruits and vegetables ripe, and then extend shelf life and the storage of packaged fruits and vegetables
Phase.But before no filling fruits and vegetables, the water deficient in air is to cause 1-MCP release, the tin foil fresh-keeping function
It will not be activated.
The invention also discloses a kind of preparation method of above-mentioned 1- methyl cyclopropenes tin foil, comprise the following steps：
1) preparation of 1- methyl cyclopropenes inclusion complex：1- methylcyclopropene gas is passed through to 5-15% modification amylose
