Abstract
Physicochemical and biochemical changes of minced flesh of lizardfish (Saurida micropectoralis) kept in air and vacuum during frozen storage at -20°C for 24 weeks were investigated. Formaldehyde and dimethylamine (DMA) contents increased with a concomitant decrease in trimethylamine oxide (TMAO) content as the storage time increased (P<0.05). Ca2+-ATPase activity decreased continuously with a coincidental decrease in the salt-soluble fraction. Disulfide bonds were increasingly formed throughout the storage (P<0.05). Nevertheless, surface hydrophobicity increased and reached a maximum at week 4 with a subsequent decrease up to the end of storage. In general, greater changes were observed in lizardfish mince kept under vacuum than in air. A marked increase in trimethylamine-N-oxide demethylase (TMAOase) activities was observed up to 6 weeks, followed by continuous decrease up to 24 weeks of storage. TMAOase activity, as well as formaldehyde formation, could be reduced to some extent with packaging containing oxygen. © 2004 Elsevier Ltd. All rights reserved.
