Postharvest Quality of Kiwifruit (Actinidia chinensis) after X-ray Irradiation Quarantine Treatment

The quality of two kiwifruit varieties [ Actinidia chinensis var. deliciosa , ‘Hayward’ (green-fleshed), and ‘Zesy002’ (gold-fleshed)] was determined after X-ray irradiation at doses suitable for disinfestation quarantine pests. Fruit were treated with 0, 200, 400, 600, or 800 Gy stored 14 days 2 °C. Irradiation did not affect soluble solids content, respiration rate, taste. Minimal softening occurred to 400 Gy. No visible radiation injury, scald, discoloration observed. treatment ≤800 would ensure visual, compositional, sensory while providing security.
