Physical and physicochemical indexes in tomato fruits

Abstract

With the aim of selecting the best cultivars for industrialization purposes, to obtain tomato (Licopersicon esculentum, Mill), paste and purée, some characteristics of varieties produced in the South of the Minas Gerais State were determined, during three different periods. On the ripened fruits, the following determinations were made: weight, main diameters, pulp yields, purée yields, pH, titrable acidity, total and soluble solids and moisture content. Among the cultivars under study the following were selected: Chico Grande, Chico III, M128, M129, Rossol and H1706, taking into account their higher productivity and the best climatic adaptability. It was concluded that there was no major significance among cultivars from the chemical of physicochemical point of view and cultivars Rossol and H1706 were the most appropriate for industrial purposes, considering their higher purée yields.
