The objective of this study was to determine the influence of irradiation-induced physiological responses on quality parameters in ‘Fuji’ apples. Apples were treated at 377 and 1148 Gy, stored for 7 days at 1 °C to mimic ground transportation to Mexico and another 7 days at ambient temperature to simulate retail and consumer storage conditions. Irradiation suppressed ethylene production, especially in the 1148 Gy treated apples, which was consistent with lower activities of 1-aminocyclopropane-1-carboxylate oxidase (ACO). A dose-dependent increase in respiration rate corresponded with decreases in titratable acidity (TA) and organic acids. Higher electrolyte leakage in apples irradiated at the …
