Abstract

Quality changes of three strawberry cultivars ('Camarosa', 'Cavendish' and 'Chandler') packed with perforated plastic boxes during the cold storage (0 degreesC and 90-95% relative humidity) were investigated. Weight loss of strawberries increased as a function of storage time. Strawberry fruits were firmer in cold-air storage than at harvest. Colorimeter values (L*, a*, b*, C* and h) of strawberries stored 10 days decreased in comparison to initial values in all cultivars. Titratable acidity and vitamin C (ascorbic acid) contents of fruits decreased during the storage time. While the total soluble solid content of 'Cavendish' decreased, an increase was observed in 'Chandler'. Citric acid content showed an increase depending on storage time, whereas malic acid contents fluctuated during the storage period and decreased in all cultivars at the end of storage time. The postharvest life based on sensory evaluation was 10 days for 'Camarosa', 'Cavendish' and 'Chandler' fruits stored in cold air.
