Summary

In order to elucidate the deterioration and its control for the gel-forming ability of lizardfish, formaldehyde (FA) and tyrosine accumulated in the fillets packaged with air, nitrogen (N2) and oxygen were determined during storage at 5 °C. The amount of Tyr did not increase; however, that of FA increased, especially in the samples packed with N2 in the earlier periods of storage. It was presumed that an enzyme, trimethylamine N-oxide demethylase, in the fillets acts sufficiently under oxygen-deficient storage, and the FA produced is rapidly combined with fish protein, causing deterioration of the gel-forming ability, before protease of fillets act on the fish protein. These findings suggested that avoidance of oxygen deficiency during storage is effective in keeping the gel-forming ability of lizardfish.
