The shelf-life of fresh-cut apples is limited because of their high water loss, deterioration rate, and surface browning. In this research, the effects of ultrasonic, ultrasonic+carboxymethyl cellulose (CMC) 1% coatings, ultrasonic +ascorbic acid (AA) 2%, and combination of ultrasonic +AA 2% and CMC 1% on fresh-cut apples were studied. Physicochemical, antioxidant properties, and microbial stability of ready to eat treated fresh-cut apple was investigated during storage at 4 °C for 12 days. Results showed that the treated fresh-cut had less changes of L*, esh rmness, soluble solid content, and titratable acidity than that of untreated. Vitamin C, total phenol, total avonoid, antioxidant capacity, and superoxide dismutase activity were greater in treated freshcut apple than that of untreated ones. Ultrasonic application mostly declined polyphenol oxidase and peroxidase activity changes. The combined treatment of ultrasonic +AA 2% + CMC 1% had the greatest impact on reducing microbial load among the treatments. These results revealed that the simultaneous application of ultrasonic and AA followed by CMC coating might have the potential to be used in minimally processed industry.
