Abstract
This invention is related to controlled release formulations of volatile antimicrobial compounds against pathogens affecting meats, plants, or plant parts or dairy products. Provided are delivery systems in the form of coatings or films, where controlled release of their volatile components in vapor form is triggered by high relative humidity. The volatile component may include, for example volatile antimicrobial liquids including low molecular weight alcohols and/or aldehydes, 1-methylcyclopropene, and/or other volatile fungicides.

A method for preparing a humidity-activated material, the method comprising:
- (a) dispersing a volatile component in an aqueous solution comprising a binder component to give a mixture;
- (b) casting the mixture onto a packaging material;
- and
- (c) solidifying the mixture to generate a coating on the packaging material,
- wherein the mixture has a viscosity greater than 250 cPs.
A method for preparing a humidity-activated material, the method comprising:
- (a) dispersing a volatile component in an aqueous solution comprising a binder component to give a mixture;
- (b) casting the mixture onto a solid substrate;
- and
- (c) solidifying the mixture to generate a coating on the solid substrate,
- wherein the mixture has a viscosity greater than 250 cPs.
