PROBLEM TO BE SOLVED: To provide a method for producing ATP-holding micronized fish having gel-formative ability and causing no cold denaturation for a long term by conducting no bleach with water, and using no additive such as a freeze denaturation-preventive agent to provide additive-free micronized fish or additive-free frozen micronized fish obtained by the method and to provide a paste produced from the micronized fish.SOLUTION: The method for producing micronized fish includes adding ATP aqueous solution (pH-7.0) while micronizing ATP-lost fish with a micronizing means. Another version of the method for producing ATP-holding micronized fish includes micronizing fish richly containing ATP in a short time.COPYRIGHT: (C)2010,JPO&INPIT【課題】水晒しを行なわず、冷凍変性防止剤等の添加物を一切使わず、ゲル化形成能が高く、長期間にわたり低温変性を生じない微細化魚肉を製造する方法、該方法によって得られた添加物を一切含まない微細化魚肉、又は冷凍微細化魚肉、又は該微細化魚肉から製造された練物を提供すること【解決手段】ATPの消失した魚肉を微細化手段で微細化しながらATP水溶液(pH-7.0)を添加する微細化魚肉の製造方法。ATP含量の高い魚肉を短時間で微細化することを特徴とするATPを保持した微細化魚肉の製造方法。【選択図】なし
