title: Analysis of sensory and physicochemical data on commercial tomato purée with pattern recognition techniques.
abstract: The correlations between analytical parameters and some typical sensory attributes of commercial tomato purée (8-14 degrees Brix) were studied. In order to ensure the widest possible variance multivariate analyses was used. A model was obtained that could describe the different contribution of the analytical variables to the sensory attributes examined. Cluster analysis revealed the existence of two distinct sub-groups; traditional by tomato purée and organically produced tomato purée.
