Abstract
Cyclodextrin compositions including one or more radiation polymerizable monomers and a cyclodextrin inclusion complex, the cyclodextrin inclusion complex including a cyclodextrin compound and an olefinic inhibitor of an ethylene generation in produce, are coated onto packaging materials and cured. Treated containers and treated package inserts having the cured cyclodextrin compositions are useful in packaging of respiring plant materials.
Claims9
A cyclodextrin composition comprising one or more radiation polymerizable monomers, a photoinitiator and a cyclodextrin inclusion complex, the cyclodextrin inclusion complex comprising a cyclodextrin compound and an olefinic inhibitor of an ethylene generation in produce, the olefinic inhibitor comprising a compound having the structure
- wherein each of R1, R2 are independently hydrogen or a C1-16 hydrocarbyl group and R3 and R4 are independently hydrogen or a C1-16 hydrocarbyl group with the proviso that at least one of R1 or R2 is methyl.
A method of making a cured cyclodextrin composition, the method comprising
- a. forming a cyclodextrin composition comprising one or more radiation polymerizable monomers, a photoinitiator and about 0.05 wt % to 10 wt % of a cyclodextrin inclusion complex based on the weight of the cyclodextrin composition, the cyclodextrin inclusion complex comprising cyclodextrin and an olefinic inhibitor of an ethylene generation in produce, the olefinic inhibitor comprising a compound having the structure
- wherein each of R1, R2 are independently hydrogen or a C1-16 hydrocarbyl group and R3 and R4 are independently hydrogen or a C1-16 hydrocarbyl group with the proviso that at least one of R1 or R2 is methyl;
- b. disposing the cyclodextrin composition onto at least a portion of one surface of a packaging material at a thickness of about 0.01 micron to 1 millimeter to form a coating;
- and
- c. exposing the coating to a source of radiation to form a cured cyclodextrin composition.
