Abstract: This invention relates to inducible release vehicle comprised of crosslinked carbohydrates or proteins and an active ingredient. The release is induced by an external stimulus, e.g. an enzyme such as amylase. Such a vehicle can particularly be used in applications for preventing microbial decay or combating microbial infections. Other uses are for oral applications such as providing antdaries or flavoring compounds and for pharmaceutical and/or nutraceutical applications.

Abstract: This invention relates to an antimicrobial substance in a covering which can be decomposed by microorganisms, e.g. of carbohydrates and/or proteins. This can particularly be used in an active package for preventing microbial decay of the packaged goods. For this purpose, such a covering is provided in or on the packaging material, causing the antimicrobial substance to be released only at the location where and the moment when there is microbial activity. Such a package is very suitable for packaging perishable foods.
