Abstract
The present invention provides a composition for absorbing ethylene and other unsaturated compounds. The composition comprises electron-deficient dienes or trienes incorporated in an ethylene-permeable substrate. In a preferred form the composition comprises tetrazine dicarboxyoctyl ester in an ethylene-permeable, hydrophobic polymeric substrate. In a preferred form the composition is cast as a thin film suitable for wrapping and/or packaging. The present invention also provides a method of retarding the ripening or senescence of fruit and other plant material comprising confining the fruit or plant material in an ambient atmosphere subject to the ethylene-absorbing action of a composition comprising an electron-deficient diene or triene incorporated in an ethylene-permeable substrate.
Claims16
A composition for absorbing gaseous unsaturated compounds comprising a tetrazine having electron withdrawing substituent incorporated in an ethylene permeable substrate such that upon exposure to ethylene, the said tetrazine reacts with ethylene rapidly and irreversibly.
A packaging material for retarding the ripening or senescence of fruit or other plant material comprising an ethylene permeable substrate wherein a composition for absorbing gaseous unsaturated compounds comprising tetrazine having an electron withdrawing substituent is incorporated therein;
- such that upon exposure to ethylene, the tetrazine reacts with ethylene rapidly and irreversibly.
