Parameters influencing the migration of trace metals in uncoated fruit cans

Résumé

The migration of eight trace elements (Fe, Sn, Cr, Cd, Pb, Ni, Cu, and Zn) was monitored for fruits canned in uncoated tinplate cans under different storage conditions until the shelf life. The levels of most of these elements significantly increased with storage time and were also affected by storage temperature. Particularly, storage at 40°C (simulating sunlight exposure of the cans) caused important release of Sn and Fe so that canned foods did not comply with regulation. Can denting accelerated the migration of several metals, especially Fe and Sn. Moreover, Fe and Sn levels drastically increased in fruits kept in open cans stored in the fridge for a few days. Small pieces of fruits contained higher level of metals than larger ones, and the side seam coating reduced the migration of trace elements.
