Abstract
Fruit of 'Climax' rabbiteye blueberries (Vaccinium ashei Reade) were i rradiated by a linear accelerator at 0, 0.25, 0.5, 0.75, 1.0, and 1.25 kGy and evaluated for various quality attributes after storage for 1, 3, 7, or 14 days at 1C plus 2 days at 15C, respectively. Weight loss increased during storage and averaged 4.2% after the final inspection and was not affected by irradiation dosage. About 5% of total berries were decayed after 14 days at 1C, about 6% after the final inspection at 15C, but decay was not affected by the level of irradiation. Electr olyte leakage, skin color, total soluble solids, acidity, and pH were also not affected by irradiation dosage. There was a significant decli ne in berry firmness, flavor, and texture as dosage increased. Berries treated at 1.0 kGy or above were softer and had lower flavor and text ure preference scores than berries treated at lower dosages or nontrea ted berries.
