The cryoprotective effects of hydrogenated linear oligosaccharides on the denaturation of walleye pollack-surimi proteins stored in a frozen state at -30°C were studied by measuring the total activity of myofibrillar Ca-ATPase and evaluations of the gelling properties of surimi.
It was found that the cryoprotective effects of hydrogenated linear oligosaccharides (DPn 2.7 and MWn 462) were similar to those of sucrose and D-sorbitol without any deteriorative influences on the properties of surimi or kamaboko. It was also discussed that the cryopro-tective effects of polyols on the fish muscle proteins were correlated to the amount of un-freezable water in surimi.
