| Abstract:
The aim of this study was to correlate physical or chemical measurements data with sensory attributes of fourteen apricot cultivars harvested in 2000. These cultivars were chosen according to their contrasted sweetness, acidity, texture and aroma. The fruits were described by sensory analysis (13 taste and texture attributes), chemical (9) and physical (2) parameters. The fourteen cultivars were harvested at a similar maturity stage according to commercial practices. Analysis and sensory assessment were carried out on equivalent fruits from homogeneous samples. A PCA analysis based on instrumental measurements with a projection of sensory attributes expressed large differences between the fourteen cultivars mostly on the sweetness/acidity ratio, the weight and the firmness. The relationship between analysed attributes and the projected ones expressed that sensory attributes such as sweetness, firmness were foreseeable by instrument measures, while taste, fibrousness, mealiness were not. Sensory analysis thus remains an indispensable tool. | |
