Abstract

The objective of this study was to evaluate the physico-chemical and rheological characteristics of two tomato varieties, Vimeiro and Runner, grown in Algarve and West of Portugal, during the harvest season. The samples were submitted to analysis of weight, caliber, moisture, total soluble solids, total titratable acidity, lycopene, color and hardness. Significant differences were observed for all parameters when considering the factors producer X variety X region. For lycopene and hardness no differences notorious between varied and regions were observed. The principal components analysis identified 3 clusters. Regarding to cluster 1, Vimeiro variety produced in West of Portugal, higher weight, higher caliber and a more intense and red color were found. In the cluster 2, Runner variety produced in West of Portugal, samples shows a moisture content significantly higher. Cluster 3, Runner variety produced in Algarve, is strongly marked by the coordinate H°. The standard deviations associated with the color coordinate a * were accentuated in the two regions, but more representative in the Algarve, revealing some heterogeneity of the fruits. It is concluded that the tomato produced in the West presents differentiating characteristics, especially with respect to the superior weight and caliber.
