Abstract
|
|
|
|
A seaweed Ecklonia cava from Jeju island was irradiated with 0.1∼6 Mrad of gamma-rays and the yield and viscosity characteristics of alginates from it were examined. Irradiation below 1 Mrad dose brought about a 70% increase in the yield while higher doses caused slight decreases. Viscosity behavior of alginates below 0.5 Mrad dose was rot altered while the viscosity decreased markedly above 1 Mrad dose, likely due to the depolymerization.
