Polyphosphates such as sodium or potassium pyrophosphate, tripolyphosphate, hexa-metaphosphate and metaphosphate were effective in increasing agar extractability when they were added in the cooking process of Gelidium pacificum OKAMURA and alkali-treated Gracilaria verrucosa (HUDSON) PAPENFUSS, at 1×10-3M concentration levels. There was a tendency for the effect of polyphosphate on agar extraction to become greater with increasing degree of condensation of phosphate. The results were especially remarkable with alkali-treated Gracilaria. Monobasic salts of orthophosphate had some effect on extractability of agar from Gracilaria, but tribasic orthophosphates were ineffective with both Gelidium and Gracilaria.
