  • Delivery system for cyclopropenes
    Patent number: 6762153
    Abstract: The present invention relates to complexes formed from molecular encapsulation agents such as cyclodextrin, and cyclopropene and its derivatives such as methylcyclopropene, which are capable of inhibiting the ethylene response in plants. More specifically this invention relates to compositions of cyclopropenes and molecular encapsulation agents containing additives to improve the release of the cyclopropene when the composition is contacted with water.
    Type: Grant

  • Method and device for the generation of cyclopropene compounds
    Publication number: 20030220201
    Abstract: A device and method for generating cyclopropene gas comprising bubbling a gas through a vessel that contains water. A cyclopropene/cyclodextrin complex is added to the water to form an aqueous suspension. Cyclopropenes are used to inhibit the ethylene response in plants and plant products, such as fruits and vegetables. The device of the invention may treat small volume facilities as well as very large volume storage facilities, such as warehouses and the like. The bubbled gas rapidly and completely liberates the cyclopropene gas from its cyclodextrin carrier to provide a cost effective and efficient treatment against the ethylene response in plants.
