Sliced strawberries (cvs. 'Pajaro' and 'G-3') and partially ripe pears (cv. 'Barlett') were dipped in various solutions (citric acid, ascorbic acid, and/or calcium chloride) and stored in air or in controlled atmospheres (CA) for 7 days at 2.5°C followed by one day at 20°C. Fruit slices respired at a higher rate than whole foods at both temperatures. CA storage suppressed respiration and ethylene production rates of sliced fruit. Firmness of strawberry and pear slices was mantained at storage in air + 12% and in a 0.5 % O2 atmosphere, respectively, or by dipping in 1% calcium chloride. These treatments also resulted in lighter colored pears slices than the air control treatment.
