Abstract : The TSS, starch, sugars, total carotenoid pigments and pH were positively correlated, while moisture, acidity, ascorbic acid and tannins were negatively correlated, with fruit specific gravity at the time of harvest. During transport (48 h) and storage (10°C for up to 32 days), a rise (higher with higher specific gravity) followed by a decline was observed in TSS, reducing and total sugars and total carotenoid pigments. The content of non-reducing sugars, after attaining a peak, remained more or less constant, while the starch content declined during storage. On the other hand, moisture, acidity, ascorbic acid and tannins decreased continuously, while there was a steady rise in physiological weight loss and pH of the fruits. Fruits with specific gravity > 1.00 were better in quality than the not-fully-mature fruits.
