Amorphophallus campanulatus (Roxb.) or elephant foot yam has been reported to possess antioxidant, antibacterial, antifungal, hepatoprotective and cytotoxic activities. The corm contains glucose, galactose, mannose, calcium oxalate, rhamnose and xylose. This research aimed to study the optimal condition of konjac noodle production and determine the calcium oxalate containing konjac noodle. Two hundred gram of Amorphophallus campanulatus (Roxb.) were boiled and milled. The milled A. campanulatus were mixed with water until homogeneous. Limewater were added into the homogenized A. campanulatus and made a flat plate. Konjac noodle were obtained by cutting the A. campanulatus flat plate and boiled for 30 minute. Boiled konjac noodle were soaked in water for 2 hours. Calcium oxalate content, color measurement (L*-a*-b*) and preference test / acceptance tests were evaluated.
