Abstract

Effect of organic acids, mango peel, colloidal corrosion inhibitors and lacquering of cans on uptake of Sn by canned mango nectar (MN) was investigated, using MN of 15 degree Brix and 0.3% acidity. After storage of cans of MN for 1 yr at 25-28 degree C or 37 degree C, Sn contents were 200 and 510 ppm respectively. Corresponding values for other fruit juices were: pineapple, 180 and 320 ppm; orange, 153 and 295 ppm; and tomato, 148 and 270 ppm. Addition of 0.2% solutions of sodium alginate, carboxymethyl cellulose or gelatin reduced uptake of Sn, but agar-agar, glycine and citrus pectin were ineffective. Addition of mango peel had no effect on dissolution of Sn. Packaging of MN in lacquered or partially lacquered cans reduced Sn uptake, but imparted a lacquer off-flavour. In a model expt.
