Abstract

The elastic texture in pre-rigor fish muscle is valuable for the preparation of sliced raw fish. For the purpose of delaying the ATP degradation and the pH decrease in relation to the delay of rigor development in red sea-bream muscle during storage, spinal cord destruction was tried immediately after stabbing the medulla oblongata. In spinal cord destroyed fish muscle, the ATP level, the pH value, and the breaking strength were high at the initial stage of storage, and theirdecline was slow during storage at 3°C. The ultimate values of pH and breaking strength were high. In the case of spinal cord destroyed fish, the rigor index increment ceased temporarily and the index reached 100% at 12-19h behind the controls. The peak value of generated rigor tension was small. The high breakingstrength throughout storage was ascribed to less structure weakening of muscle because the generatedtension was small due to the delay of rigor development. The high breaking strength is also ascribed to less proteolytic breakdown of the pericellular connective tissue of fish muscle due to the relatively high pH condition.
