Gelling interactions of phycocolloids extracted from red algae with a galactomannan from locust bean and a glucomannan from konjac tuber

The synergistic interaction between three red algae extracts and the galactomannan from locust bean (Ceratonia siliqua L.) and the glucomannan from the konjac tuber (Amorphophallus konjac C. Koch (syn.A. rivieri Durien var. konjac (C. Kock) Engler)) has been characterized in terms of gel properties. The extract obtained fromEucheuma alvarezii Doty (E. cottonii of commerce) was highly synergistic with bothkonjac flour and locust bean gum.Furcellaria fastigiata (Huds.) Lamour andEucheuma gelatinae (Esper) extracts were only slightly synergistic with locust bean gum, but were found to be highly synergistic with konjac flour.
