Abstract
A coating for harvested agricultural commodities which delays ripening and controls decay is described. The coating comprises a modified chitosan matrix containing a yeast antagonistic to postharvest pathogens. The modified chitosan may be carboxymethylchitosan or glycolchitosan. The combined fungicidal activities of the modified chitosan and the antagonistic yeast make this formulation an attractive preservative which is superior to existing coatings and ensures the even distribution of the antagonistic yeast over the surface of the harvested commodity, thus increasing its effectiveness.
