抄録

The demand of poultry meats, especially broiler, should be increased toward 21st century as one of the most promising protein resources. The production of broiler is accompanied with large amounts of waste feathers. We have focused attention on the extraction of proteins from waste feathers and a simple extraction process has been developed. The extracted protein liquid indicates a strong foamability, which should be useful as a raw light material to be mixed with a solid raw material to produce a low density material. The foaming characteristics have been experimentally evaluated and ferric sulphate has been confirmed to reinforce and stabilise generated protein foams. The optimal additions of ferric sulphate and the protein liquid have also been decided by observing the drainage rate of liquid from generated foam films. To demonstrate the capability of protein foams to produce low density materials bubble cement and bubble mortar have been evaluated in terms of the mouldability, bubble dispersibility and compressive strength. The mouldability and the homogeneous dispersion of bubbles in a moulded material have been guaranteed even when the bubble volume fraction exceeds 0.5. We regard this demonstration as a convincing evidence of the capability of protein foams as a light raw material to be mixed with a solid raw material in producing a low density material with high performances in heat, sound and water protection.
