| Outline of Final Research Achievements |
We identified the compound responsible for the odor of yellowtail meat and investigated the changes in their compounds during storage to be able to eat the good quality of fish for everyone. Quality preservation techniques for raw fish meat such as nitrogen substituted packaging method et al. were also developed. The dark muscle largely involved in the odor of yellowtail meat before and after storage compared to the other parts of muscles. Important components of its odor were several compounds such as 2,3-butanedione as well as unknown compounds which had low a threshold value. The strongest odor was also an unknown compound (Kovats index: 1387) which had fishy and plastic characteristic. Incease in high molecular unknown compounds, which was unpleasant, was responsible for the odor change of yellowtail meat during storage. On the other hand, nitrogen substituted packaging depressed the browning and the lipid oxidation as well as the odor change of yellowtail meat.
