Study of Zinc Content in Biofortified Tomato

Abstract

The aim of this work is to study the content of zinc in tomato biofortified vegetables (peppers, eggplant, and tomatoes). Objectives of the study are: to determine the content of zinc in tomato vegetables during cultivation of which agronomic biofortification was applied using environmentally safe organic fertilizer of new generation – “Riverm”; to compare zinc content in biofortified vegetables with the content of zinc in samples of vegetables grown by standard conditions. This paper uses laboratory (physical) methods; definition of zinc content in vegetables was performed with the use of voltampermetric analyzer. The research results give us the right to conclude that the use of fertilizer "Riverm" during cultivation of sweet pepper, eggplant and tomatoes helps them to be enriched by zinc. Biofortified vegetables contain 6,60-8,59 % of zinc more than control samples. Grown vegetables become a readily available source of zinc for humans and contribute to overcoming the "hidden hunger" caused by deficiency of this essential micronutrient in food.
