Studies of changes in carbohydrate and mineral constituents during growth and development of pineapple var. Kew revealed that starch, total, non reducing and reducing sugars concentration increased upto 165 days of growth. Within the developmental period, the fruit crossed three distinct discrete physical stages viz., premature (0 to 120 days), mature (120 to 150 early and 150 to 165 late), ripe (at 165 days). At fully ripe stage, the concentration of biochemical constituents were: Starch (3.51 per cent), Total sugar (8.76 per cent), Non-reducing sugar (1.53 per cent), Reducing sugar (7.15 per cent), Dry matter (10.60 per cent), Ash (0.41 per cent), Nitrogen (57.2 mg/100 g), Phosphorus (1.48 mg/100 g), Potassium (220 mg/100 g), Calcium (53 mg/100 g), Magnesium (64 mg/100 g) and Iron (0.7 mg/100 g).
