The seasonal changes in the kamaboko-forming ability of horse mackerel caug
ht in large quantities by purse seiners between November 1998 and December
1999 offshore from Nagasaki were investigated to clarify the chemical chara
cteristics for utilization as raw materials for fish jelly products. The ka
maboko-forming ability of pastes, which were prepared from the meat with no
leaching (otoshimi) and with leaching in fresh water or alkaline salt wate
r, was low during and just after breeding from February to June. The paste
prepared in this season was characterized by difficult-setting and easy gel
weakning. Although meat pastes leached with alkaline salt water and fresh
water showed similar setting and disintegrating characteristics, the former
alleviated disintegration and enhanced the kamaboko-forming ability of the
meat paste when heated at 90 degreesC.
