The present research aimed to evaluate changes in quality attributes of a new late ripening cultivar during cold storage. Fruit from 'Farbaly' (Carmingo®) were harvested at commercial maturity stage and stored in air at 1°C with 95% RH. Weight loss, respiration (O(2) uptake and CO(2) production) and ethylene production rates, peel colour, fruit firmness, concentration of total phenolics, flavonoids and carotenoids, total antioxidant capacity, β-carotene, β-cryptoxanthin, γ-carotene and of the acids ascorbic, malic and citric were determined at 20°C after 0, 13 and 19 d storage. Total soluble solids, titratable acidity and pH were determined only at harvest, while sensory evaluation was carried out on day 19. Results showed that weight loss reached 8% at the end of the experiment. During storage, increases in ethylene production and decreases in firmness were the major changes observed. Respiration rates, β-carotene concentration and ho colour parameter decreased, with ho changes indicating a slight blushing development, total flavonoids increased slightly, while minor and non-consistent changes in total carotenoids occurred. Neither decay nor disorders were observed. Panelists rated the fruit as apricots of large size, firm and with good colour and taste. Conclusively, 'Farbaly' is a promising apricot cultivar with good quality traits and high storability potential.
