Impact on chemical profile in apple juice and cider made from unripe, ripe and senescent dessert varieties

The chemical profile of juices and ciders prepared with three varieties of dessert apples (Gala, Lis Gala and Fuji Suprema) at three different ripening stages (unripe, ripe and senescent) were established. Sixty-five analytical parameters were determined and the data processed using two-way ANOVA and principal component analysis (PCA). The phenolic content and antioxidant capacity in the juices were different between the cultivars. However, after fermentation phenol content reduced (15%) only in the unripe ciders. The juices prepared with unripe fruit contained 55% less volatile compounds than the juices from ripe and senescent fruit, while the cider made with senescent apples contained 24-52% more volatile (Lis Gala and Gala, respectively) than the cider from unripe apples. Variety, ripening stage and their interaction showed significant effect (p < 0.05) for most of the variables analysed. PCA analysis was used to classify juices and ciders in relationship with the variables analysed. Variety had a higher impact than ripening stage. The choice of variety and the knowledge of the cultivar composition, which increase or decrease along the maturation, allows at the producer to establish the sensory quality of the apple juice.
