The effect of 50, 100 and 200 mg/100 g of ascorbic acid added to Badami mango nectar containing 20% pulp, 15 degree Brix and 0.3% acidity, on corrosion of tin plate during storage at 37 degree C for 12 months was studied. During cut out analysis ascorbic acid, Sn and furfural were determined. Sn content of mango nectar initially and after the addition of 50, 100, 200 mg/100 g ascorbic acid respectively was: initial, 38, 40, 39, 38; after 3 months, 75, 90, 122, 145; 6 months, 146, 169, 183, 229; 9 months, 262, 293, 320, 380; 12 months, 318, 363, 382, 496. Sn content and extent of corrosion therefore increased with increase in the concn. of ascorbic acid. With increase in extent of corrosion ascorbic acid content decreased significantly. Furfural increased with increase in concn. of ascorbic acid. Results indicate that ascorbic acid and its degradation product furfural, act as accelerators of corrosion when added to mango nectar.
