Compositions and Methods for Differential Release of 1-Methylcyclopropene

(canceled)

A method of disgorging 1-methylcyclopropene gas from an α-cyclodextrin clathrate thereof, the method comprising

• a. obtaining a particulate consisting of 85% or more by weight of a 1-methylcyclopropene clathrate of α-cyclodextrin and 0% to 15% by weight of α-cyclodextrin, the particulate having a mean particle size between 3 μm and 15 μm as determined by a volume-based method;
• and
• b. subjecting the particulate to disgorgement conditions of 1 atm pressure, 0° C. to 50° C., and 80% to 100% relative humidity.

A method of making a 1-methylcyclopropene clathrate of α-cyclodextrin particulate having a mean particle size between 3 μm and 15 μm, the method comprising

• a. obtaining a particulate product consisting of 85% or more by weight of a 1-methylcyclopropene clathrate of α-cyclodextrin and 0% to 15% by weight of α-cyclodextrin, the particulate having a mean particle size between 30 μm and 100 μm as determined by a volume-based method;
• b. comminuting the particulate product to form a comminuted particulate, and
• c. classifying the comminuted particulate to select a mean particle size between 3 μm and 15 μm.
