Abstract
In order to compare fish actomyosin(AM) with animal AM from the standpoint of oxidative denaturation, AM solutions were prepared from the muscles of carp and rabbit and stored at 4°C. The relationships between the oxidation of SH and lipid and the concomitant changes in solubility and ATPase activity were investigated. The results were as follows.<br> 1)In rabbit AM, there wax little change in the SH and SS contents for about 14days and only a slight decrease in the ATPase activity. In carp AM, there was a dramatic decrease in ATPase activity and the SH content decreased while that of SS increased. However, these changes were suppressed by storage in nitrogen gas.<br> 2)Oxidation of lipids occurred after about 10 days in carp but was delayed in rabbit.<br> 3)Even for carp, the amount of salt-insoluble AM was only 4% after storage for 16 days. During this period, the salt-soluble fraction increased in SS content while the ATPase activity was reduced by half.<br> From these results, it wax conjectured that carp AM is more susceptible to oxidation than rabbit AM, and that oxidation is associated with the decrease of ATPase activity in carp AM stored at 4°C.
