Abstract
|
|
|
Gracilaria verrucosa and Gelidium amattsii collected from Wando, Yeosoo and Namhae districts Gracilaria sp. imported from Manila, and Ecklonia cava from Cheju island were investigated to raise the extraction yield of agar or alginic acid. The results are summarized as follows.
In agar extraction from domestic seaweeds, Gelidium sp. showed 8-10% yield increase by gamma-irradiation whereas Gracilaria sp. exhibited no effect. In Manila seaweed, gamma-irradiation (1.5 Mrad) caused 25-30% increase in agar extraction and the properties of agar sample by these methods were acceptable. In alginic acid extraction from Ecklonia sp., gamma-irradiation (0.3 Mrad) showed 6% yield increase.
