Résumé

The relations between the juiciness and firmness of apples stored under various conditions were investigated taking into consideration the effect of harvest date. After removing apples from the store, they were subjected to additional storage in a cold room or at room temperature for various periods to diversify their degree of ripeness. Fruits were then sorted according to increasing firmness and divided into 12 classes. Juiciness of fruits based on instrumental measurement and sensory appraisal was then determined. For all investigated cultivars the juiciness of stored apples was positively correlated with fruit firmness; however, some maxima in juice release during pressing for very firm fruits were noticed. During the sensory assessment, as in instrumental measurement, the juiciness intensity sensation generally enhanced with increasing fruit firmness, although at a higher fruit firmness a tendency towards lowering the juiciness rating intensity sensation was observed.
