Abstract
【解決手段】絹蛋白から分取された繊維状フィブロインを、好ましくはアルカリ水溶液を含浸させた後、100〜150℃の過熱水蒸気に曝して強度劣化させた後、粉末状に粉砕することからなる絹フィブロイン粉末の製造方法とする。または、絹蛋白から分取された繊維状フィブロインを、100〜150℃の加圧雰囲気下で過酸化水素水溶液に接触させ、次いで脱過酸化水素処理および乾燥後に、粉末状に粉砕することからなる絹フィブロイン粉末の製造方法とする。さらにまた、絹蛋白から分取された繊維状フィブロインに過酸化水素水溶液を含浸して凍結し、次いで脱過酸化水素処理および乾燥処理した後、粉末状に粉砕することからなる絹フィブロイン粉末の製造方法とする。
