Abstract
The yield and quality of agar extracted from γ-irnidialcd Gelidiella acerosa were evaluated. Increasing radiation dose resulted in increasing agar yield. A radiation dose of 15 kGy caused a yield increase of 130%; however, the quality of agar was adversely affected as shown by the decrease in gel strength. Chemical analyses indicated that irradiation decreased the 3,6-anhydrogalactose content of agar, whereas, the sulfate level did not vary significantly. A comparison between boiling and pressure-cooking as methods of agar extraction showed that the latter increased agar yield, but lowered quality.
