Research Concerning the Evolution of Heavy Metals Content in the Fresh and Metal Can Preserved Vegetables (Tomatoes)

Abstract

The research was carried out with the following purpose:-to determine the level of heavy metal accumulation in the tissues of certain vegetable species taken from polluted industrial areas and the degree to which their content is modified during technological processing operations;-to study the possibilities in which fresh vegetable species with a high content of heavy metals (an exceed of LMA) can be used in the canning industry, in conditions assuring full safety for consumers. Research findings have revealed that tomato juice content of heavy metals is significantly lower compared to that of fresh tomatoes (especially in the case of lead and cadmium).
