In this study, the areca taro was treated by high energy electron beam with irradiation dose of 0.1,0.3,0.5,0.7, and 1.0 kGy. The effects of different irradiation doses on areca taro storage and antioxidant enzymes were studied. The results showed that low-dose electron beam irradiation could significantly reduce the decay rate of areca taro and better control the germination, and had little effect on the hardness, color and sensory quality. Meanwhile, they could maintain the activities of peroxidase, glutathione reductase and catalase. Among them, 0.1~0.5 kGy could be used as a suitable dose for irradiation storage of areca taro.
