Abstract

The influence of different fractions of pineapple juice (amino acid (AA), sugar, sugar + organic acid (OA), and OA alone) on corrosion of tin-plate was assessed at regular intervals during storage at 37 degree C for up to 12 months. The anionic fraction consisting of OA was found responsible for corrosion of tin-plate. OA also accelerated corrosion in the presence of sugar. Corrosion was negligible with sugar alone or the AA fraction. Results indicated that pineapple products can be safely packaged in tin-plate with Sn coating of 22.4 g/m-2.
