Mahyaveh, the Iranian traditional fish sauce is a product with distinct flavor that is produced by
fermentation of small and underutilized fish species in the presence of high salt concentration. Fish
sauce is mainly used as food flavoring and seasoning in the southern provinces of Iran such as
Hormozgan and Fars. In this research, the process of Mahyaveh preparation from the Persian Gulf
anchovies was performed in the lab. Fish sauce was prepared by incubating mixtures of anchovies and
saturate brine in the pottery containers at 37 C during 54 days of fermentation. The total changes in
bacterial count and nitrogenous compounds were investigated in all of six stages of fermentation. The
results showed that the total nitrogenous compounds including formaldehyde nitrogen, amino acid
and volatile nitrogen increased sharply during the periods of fermentation but trimethylamine contents
dramatically reduced in the final stage after increasing moderately in the early stages of fermentation.
High Pearson correlation (r=0.8) between total bacterial count and trimethylamine confirmed the
existence of relationship between these variables in the process of fish sauce fermentation. The results
of SDS-PAGE pattern showed that the number and intensity of protein bands were reduced during
fermentation time.
