A composition comprising:
- (a) a complex of 1-methylcyclopropene and a-cyclodextrin and
- (b) a polymer binder selected from the group consisting of polyvinylpyrrolidone and copolymers thereof, polyvinyl alcohol and copolymers thereof, polyvinyl acetate copolymers, and combinations thereof,
- wherein the ratio of polymer binder to complex on a weight to weight basis ranges from about 0.5:1 to about 3:1,
- wherein the polymer binder has a molecular weight ranging from about 5,000 to about 15,000, and
- wherein the composition is capable of releasing the 1-methylcyclopropene in the form of a gas when exposed to moisture, the composition having a release profile characterized in that when exposed at room temperature in a sealed vessel to conditions of 85% relative humidity, the composition releases substantially no 1-methylcyclopropene after a time period of at least 1 hour after exposure and thereafter continuously releases 1-methylcyclopropene for at least 5 hours after exposure.
