Effect of high-pressure treatment and transglutaminase on the gel-forming ability of salt-ground myofibrillar proteins from carp

Abstract

With the aim of utilizing a fresh water fish (carp) as a raw material for fish-paste products, the characteristics of gelation of myofibrillar proteins from carp by high-pressure treatment were compared with those of a marine fish (lizard fish) by heating. The effect of food additives containing transglutaminase on gel-forming ability was also examined. The breaking strength of high-pressure-induced gel was much lower than that of heat-induced gel from the salted carp meat, and that of high-pressure-induced gel from the salted meat of lizard fish. The gel-forming ability of salt-ground myofibrillar proteins by high-pressure treatment was high in the order Mf
