Low Dose Irradiation Influence on Yield and Quality of Fruit Juice

Granny Smith apples, Valencia oranges, and Pearlette grapes grown in Queensland, Australia were irradiated at 0, 75, 300 and 600 Gy. Following irradiation, juice was extracted and analysed for quality and compositional changes. Irradiation treatment significantly (p 0.05) affect yield of orange juice (OJ). Acceptability significantly (p<0.05) decreased in OJ after 600 Gy treatment. Other changes in quality and composition were minimal. Juice from irradiated apples and oranges stored at 5°C for 8 wk showed similar results.
