Consistent storage temperature of 2-5C for fresh-cut produce is difficult to maintain throughout distribution. This study determined the effects of temperature changes on the sensory quality of fresh-cut cantaloupe. Cantaloupe was processed, packaged and stored for 7 days. Samples were maintained at 4 and 10C (controls) or transferred from 4 to 10C after 24 or 48 h. Descriptive sensory analysis was used to evaluate aroma, flavor and texture after days 2, 5 and 7 of storage. Respiration and weight loss were monitored. Aroma and flavor were affected by temperature treatments. Texture was affected a little by temperature changes. Fruity/melon aroma and flavor, citrus aroma and sweet aromatic flavor were negatively affected by temperature changes compared to control treatments. Musty and rancid/painty flavors and bitter increased due to temperature changes. Respiration and moisture loss were affected more by storage at 10C than temperature change. Temperature increases during storage of fresh-cut fruit decreases product quality. Practical Applications: Ideally, fresh-cut cantaloupe should be stored at 2-5C until consumption. In the real world, this does not always happen. The purpose of this manuscript is to determine the effect on sensory quality when the storage temperature is increased slightly after 24 or 48 h after processing. Slight changes in storage temperature result in sensory quality problems that were not observed at constant storage temperatures of 4 or even 10C.
