Why does the fish stinks?
December 17, 2009 | In: Weird facts
Fish smells bad due to substance trimethylamine, a volatile compound that is formed after the death of fish, when the proteolytic bacteria (which demolishes the structures of protein) of Achromobacter genus, Pseudo-monas, Micrococcus and Bacillus, and Alteromonas putrefaciens, begin to colonize the meat.
The process continues and after the edibility period of the fish, in this way explaining the increased odor.After a while the smell stabilizes.
Measurement of trimethylamine level is the most common test to determine if a fish is fresh or not.
In other words, the bad smell of the fish is needed to determine its quality.
