titratable acidity (TA). Similarly, Fernandez-Trujillo et al. (1999) found that malate concentrations were 22% lower in 20 kPa CO 2 - stored than in air-stored fruit of seven strawberry cultivars, but the level of citric acid was unaffected by the CO 2

Instruments, Medfield, MA). Total titratable acidity (TTA) was analyzed by an automatic titrimeter (no. 9-313-10, Fisher titrimeter; Fisher, Pittsburgh); each sample supernatant (6 g) diluted in 50 mL of distilled water was titrated with 0.1 n NaOH to an
