Avaliação sensorial e reológica de diferentes cultivares de abacaxi

Abstract

Pineapple is a fruit very appreciated for its flavor, juiciness and texture. However, the susceptibility of commercial cultivars to the fungus, which causes fusarium, has limited the expansion of pineapple culture. Thus, genetic improvement programs are developing new cultivars in order to overcome this difficulty plant. Therefore, the aim of this study was to comparatively evaluate the acceptability and rheology of new pineapple cultivars ‘Imperial’, ‘Vitoria’, ‘IAC Fantástico’ and ‘Gomo de mel’, with traditional varieties already known producer and consumer: ‘Pérola’ and ‘Smooth Cayenne’. For this, acceptance test and rheological analyzes (texture profile, stress relaxation and uniaxial compression) of these cultivars were conducted and the results were evaluated by means test, internal preference map, principal component analysis and Pearson correlation. The results of this work allow us to infer that the new cultivars under study presented sensory and rheological differences in relation to the most planted and commercialized ones, being that, among the new cultivars, Vitória presented greater commercialization potential due to its greater acceptability, including in relation to Pérola and Smooth Cayenne cultivars. The Imperial cultivar, on the other hand, has little commercial viability for fresh consumption, since it presented greater hardness and rigidity, being more resistant to chewing, negatively influencing its acceptability. The cultivars IAC Fantástico and Gomo de mel had intermediate characteristics between the Vitória and Imperial cultivars.
