PROBLEM TO BE SOLVED: To provide a method for producing an oyster meat extract containing a large amount of antioxidant having high antioxidative activity by selecting a portion of an oyster meat extract containing a large amount of antioxidant having high antioxidative activity, and adopting an extraction method by which the large amount of antioxidant having high antioxidative activity can be obtained, thereby attaining efficient extraction of a large amount of useful oyster meat extract containing the antioxidant having extremely high antioxidative activity, to produce the oyster meat extract containing the large amount of antioxidant having high antioxidative activity.SOLUTION: The method includes storing oyster meat 3 in an extraction container 2 containing an aqueous solution 1, extracting the oyster meat extract from the oyster meat 3 to produce a liquid extract, pouring the produced liquid 7 into a centrifugal separator, and rotating the centrifugal separator at a centrifugal acceleration so as to separate and take out the antioxidant with high antioxidative activity, thus acquiring the oyster meat extract containing the large amount of antioxidant having high antioxidative activity after separation.COPYRIGHT: (C)2013,JPO&INPIT【課題】高い抗酸化力を有する抗酸化物質を多く含有するカキ肉エキス抽出物の部分を選択すると共に、高い抗酸化力を有する抗酸化物質を多く含有できる抽出法を採用し、もって極めて高い抗酸化力を持った抗酸化物質を含有する有益なカキ肉抽出物を効率よくしかも多量に抽出でき、高い抗酸化力を持つ抗酸化物質を多量に含有したカキ肉エキスを製造できる高抗酸化力を有する抗酸化物質多含有のカキ肉エキス製造方法を提供する。【解決手段】水溶液1が貯留された抽出容器2内にカキ肉3を収納し、カキ肉3からカキ肉エキスを抽出して抽出液を生成し、生成後の液7を遠心分離機に注入すると共に、高抗酸化力の抗酸化物質が分離して取りさせる遠心加速度で回転させて分離し、分離後に高抗酸化力を有する抗酸化物質を多含有させたカキ肉エキスを取得する。【選択図】図1
