摘      要：Apple fruits have components of therapeutic *** components,to a great extent,decline or decompose during post-harvest that negatively affect fruit *** fruit-filming has proved useful in maintaining these *** study aims,therefore,at enhancing Chitosan coating-film performance by mixing with some olive wastes extracts of leaf and pomace *** fruits were sprayed with six different coating formulas including chitosan-water wax coating,in addition to the uncoated ***,the total phenolic,flavonoids,antioxidants,pigments,weight loss,decay area,and microstructure were *** bioactive substances drastically changed in uncoated rather than coated ***,weight loss and decay area significantly increased in uncoated ***,the addition of olive leaf extract to chitosan coating films meaningfully reduced the gradual decline in total phenolic,flavonoids and *** pomace extract recorded the lowest influencing on anthocyanins during storage at 4±1
C for 35 ***,both olive leaf and pomace extracts enhanced the coating distribution,due to no pores were observed in the fruits’***,incorporation of olive leaf extracts with 2%into chitosan coating solution was the best formula comparable with the ***,olive wastes extracts,incorporated into chitosan fruit coatings;relatively improve the nutritional quality of apple fruits during post-harvest.
