Food Additives & Contaminants:: "The dissolution of iron and tin from tinplate cans filled with tomato pure (pH 4.34) and dioctyl sebacate oil (DOS), essential onion oil (EOO) or potassium nitrate was studied using atomic absorption spectroscopy (AAS), while nitrate was determined using high-performance liquid chromatography (HPLC). The maximum values found in cans were up to 284 mg kg-1 for tin and 513 mg kg-1 for iron at elevated storage temperature. Results indicated that the addition of EOO to tomato pure prevents the corrosion process in the case of tin, where concentrations were lowered from 223 to 28 mg kg-1 for cans with DOS oil and EOO at 20'C, respectively (inhibition rate of 87%)
