DANTAS, Sílvia Tondella et al. Stability of canned tomato sauce in tinplate cans with a reduced tin layer. Braz. J. Food Technol. [online]. 2012, vol.15, n.2, pp. 110-117. Epub Apr 24, 2012. ISSN 1981-6723. http://dx.doi.org/10.1590/S1981-67232012005000001.
The performance of three piece welded cans produced in tinplate with an internal tin layer of 2.0 g.m-2, containing 340 g of tomato sauce, was assessed by means of a storage test carried out for 24 months at 35 °C. The concentrations of tin, iron and chromium in the product, the vacuum/pressure condition and the headspace gas composition were periodically determined, as well as the internal visual appearance of the pack, allowing to conclude that such packaging was a viable option for 18 months of storage of the product from ambient temperature up to 35 °C.
