Monitoring of tin and aluminum release from food packaging to packaged food

abstract

English

Tinplate cans and aluminum cans have several advantages over other food packaging material including light weight, compact packaging, low oxygen permeability etc. According to the available literature, up to 20 bilion tin cans and 60 bilion of aluminum cans are produced in Europe each year. As a result of the use of these cans for food and beverage packaging, it is obvious that some tin and aluminum will dissolve into the food content. Long-term consumption of food containing higher concentration of tin and aluminum may adversely affect central nervous system, kidney, liver and the overall human health [1,2]. In this study tin and aluminum concentration in canned food and beverage was monitored using ICP-OES technique. In total 40 fruit samples, 28 energy drink samples and 22 bier samples in cans were analyzed and the results are presented. This study clearly showed that there is a need to pay attention to the issue of the interaction of the can with a packaged food, since increased concentrations of tin and aluminum in analyzed food samples were measured.
