The results showed that coatings reduced weight loss, the changes of firmness,soluble solids content and total acidity of coated plums were less than the uncoated plums during storage at room temperature. Andextending plums storage life from 3 to 7 days. Compared with the different composite coatings on plum quality, the effect of maizestarch- chitosan coating was better than the cassava one, and the potato starch- chitosan one was the best.
