Abstract

This study was conducted to evaluate the genotoxcity of gamma-irradiated Undaria pinnadifida after harvest for enhancing the storage and microbial safety during drying process. The harvested seaweed was irradiated with the doses of 1 and 10 kGy. The genotoxicity was evaluated by Ames test (Salmonella typhimurium reversion assay) and SOS chromotest. The results from all samples were negative in the bacterial reversion assay with S. typhimurium TA98 and TA100. No mutagenicity was detected in the assay, at both with and without metabolic activation. The SOS chromotest also indicated that the gamma-irradiated U. pinnadifida did not show any mutagenicity. Therefore, this study indicated that gamma irradiation could be used for extending the shelf-life of U. pinnadifida.
