CA 2393718

The present invention provides a method for preserving the activity of a polyene fungicide in an aqueous solution comprising providing the said aqueous solution with a chelating agent and/or an anti-oxidation agent, wherein the said chelating agent and the said anti-oxidation agent are the same agent or are different agents. Preferably, the aqueous solution further comprises a polymer. Preferably, the aqueous solution comprises a latex. The invention allows the selection of a wider range of polymer compositions for the preparation of a polymer emulsion comprising a polyene fungicide, wherein the activity of the said fungicide is at least in part stable and wherein the said emulsion is suited for the production of food coatings.

L'invention concerne un procédé pour maintenir l'activité d'un polyène fongicide dans une solution aqueuse. Ce procédé consiste à introduire un agent chélateur et/ou un agent antioxydant, identiques ou différents, dans ladite solution aqueuse. De préférence, cette solution aqueuse contient en outre un polymère et un latex. L'invention permet de sélectionner une large gamme de compositions polymères pour la préparation d'une émulsion polymère contenant un polyène fongicide, l'activité de ce dernier étant au moins en partie stable. Cette émulsion sert à la production d'enrobages alimentaires.
