Study of shelf-life of lacquered cans packed with tomato purée
The aim of this paper is to present shelf-life of lacquer cans with two different groups of lacquer coatings and different plates for body and ends. The tested samples, packed with tomato puree, sterilized and stored at temperature of 20 °C and 36 °C were opened at pre-arranged time periods. The informations about protective abilities and corrosion resistance of samples, we were characterized measuring content of head-space gas by gas chromatography (GC), tin and iron release in products by atomic absorption spectrophotometry (AAS) and visual inspection of can internal surface. The results indicated that lacquer coating with good continuity and uniformity has a greatest influence on shelf-life on caning products. This conclusion was conformed with tin and iron concentration and hydrogen contents. From a practical point of view, all types of tested containers were found to be well proctective and could be use for commercial applications.
