Resumo
Fungicides are the pesticides most widely used for tomato
cultivation, mainly dithiocarbamates. The objective of this
research was to study the efficiency of dithiocarbamate mancozeb
removal from table tomatoes, through rinsing processes. Analyses
of tomato acidity, brix, water activity, pH, and manganese content
were carried out. After rinsing tomatoes with drinking water and
solutions of vinegar (made from alcohol), sodium bicarbonate,
and dihidrated sodium dichloroisocyanurate, mancozeb levels
were assessed in skin and whole fruit, by quantifying the
manganese content present in the samples. It was observed
that the rinsing processes reduced significantly the amount of
residues in the tomatoes. The reduction of mancozeb was higher
in the skin, where it can be found in its highest concentration.
Treatments using drinking water and sodium bicarbonate solution
removed over 61% of the residues present in tomatoes skin.
