STUDIES ON GELIDIELLA ACEROSA AGAR REFINEMENT

This is the first time in using Gelidiella acerosa as the main material for the agar industry in China. Gelidiella acerosa is abundant in colloid, up to 40%. The crucial point in raising its output is acid treatment. In neutral water, the ratio of acid is 0.5-0.8%ml/ kg. The ratio of dry to wet Gelidiella acerosa is 1 : 3.5. The water used to made up the acid solution is 20 times that of the dry material, while that used to extract agar is 35-40 times that of the dry material.
