Abstract
Sea buckthorn is used as pharmaceutical product as well as nutritional supplement, especially for its antioxidative potential. As we noticed in our previous work that the electron beam irradiation could be a suitable mean to ensure the microbiological safety of sea buckthorn, in this work we have proposed to investigate the ionizing radiation influence on the sea buckthorn antioxidant characteristics. Consequently, the sea buckthorn samples have been treated by electron beams with doses up to 40 kGy and the antioxidant activity and compounds have been evaluated in comparison to the control sample after irradiation and storage at room temperature during 3 months. The study revealed that the irradiation of sea buckthorn lead to the reduction of antioxidant potential with the increase of the dose both immediately after treatment and after storage time.
