- Abstract
Each year a considerable number of peach cultivars are introduced to the market, with a wide degree of variation in fruit characteristics. Although these characteristics can be determined by physicochemical (PhC) analysis, sensory analysis is an important tool in determining how they are perceived by the consumer. The objective of this study was to evaluate the sensory acceptability, PhC parameters and their correlation in different peaches from San Pedro, Buenos Aires. A total of 320 consumers evaluated the sensory acceptability of different characteristics of whole and peeled peaches. The PhC parameters measured were: weight, soluble solids, titratable acidity, ratio, firmness, instrumental color and percentage of juice. The data were analyzed by analysis of variance, principal components and partial least squares. The cultivar that obtained the highest global acceptability was Elegant Lady. The percentages of juice, ratio, juiciness, color and sensory maturity were positively related to overall acceptability. Cultivars with greater firmness presented lower acceptability. Furthermore, this parameter had a high negative correlation with the percentage of juice and sensory juiciness. The cultivars with the greatest firmness presented the lowest percentage of juice and consumers gave them the lowest acceptability values. Despite the stipulated commercial weight standard, the consumer only punished those peaches whose weights were above it. The sensory analysis presented a useful approach to evaluate fruit quality and combining this tool with PhC analysis would contribute to the improvement and production of new cultivars.
