사과의 유통에서 내 외부 품질특성 및 외부 오염원으로부터의 안전성 확보를 위한 연구의 일환으로 사과에 감마선 조사를 실시하여 각각 와 에 저장하면서 사과의 생리화학적 및 물리적 품질특성을 살펴보았다. 연구 결과 영양 성분 및 기능성 성분의 손실이나 품질저하는 보존 온도에 의하여 결정되었고 감마선 조사에 의한 영향은 거의 나타나지 않았다. 또한 중량변화와 기계적 물성 특성 또한 감마선 조사에 의하여 영향을 받지 않았다. 색도와 관능특성은 상온 보관
The effects of gamma irradiation on the physiochemical and physical characteristics of apples were investigated during post-irradiation storage at . The contents of total and reducing sugars were analyzed and the results indicated that apples receiving 1 kGy of gamma irradiation did not show significant differences in sugar contents compared to non-irradiated controls. Important physiological characteristics were evaluated by measurement of total phenolic content and total flavonoid content, reducing power, and radical scavenging ability, and the results indicated that gamma irradiation at a dose of 1 kGy did not affect physiological activities. Changes in physical parameters such as weight loss, strength, cohesiveness and hardness, during post-irradiation storage, were temperature-dependent, whether the apples were irradiated or not The color and sensory acceptance of the apples were not affected by irradiation during cold storage. However, minor deterioration in color quality and sensory acceptance of irradiated apples was noted under ambient temperature storage. We conclude that gamma irradiation(1 kGy) does not affect apple nutritional content stability, functional properties, or physical characteristics, especially upon cold storage after radiation treatment.
