Minced meat from Walleye pollack was soaked in 3M NaCl for various time intervals within 1 day, so that NaCl concentration of the minced meat was varied among 0.9-2.1M. When the cured meat was subjected to dehydration at 30°C, the internal temperature of it was found to remain at 23°C during early 2 hours of dehydration process. Accordingly, changes in myosin heavy chains of the cured meat were compared between the processes of dehydration at 30°C and of heat treatment at 23°C. During both processes, myosin heavy chains of the meat, except the raw meat containing 0.14M NaCl and the 24h-cured meat containing high (2.1M) concentration of NaCl, decreased with concomitant formation of cross-linked myosin heavy chains. It was also shown that such changes in myosin heavy chains of the cured meat induced by dehydration at 30°C proceeded rather slowly as compared with the changes by mere beating at 23°C.
