Wahoo can be deodorized with cooking wine and vinegar.

Because the fishy odor mainly comes from weakly polar organic substances such as trimethylamine, which is soluble in ethanol. Therefore, marinating with cooking wine can remove part of the fishy flavor. In addition, trimethylamine is an alkaline substance and can also be cooked with vinegar.

It should be noted that the cooking should be done with the cooking wine first and the vinegar later. The wine has high permeability and can penetrate into the interior of the raw materials, and when heated and volatilized, it can remove the fishy taste of the fish and improve the fresh taste. After the vinegar because the vinegar in the heat can emit a kind of aroma, if put in too early, the flavor may be evaporated, making the deodorization effect is not obvious.

The reason why Spanish mackerel smells fishy:

The fishy smell of Spanish mackerel comes from a very complex class of compounds, including volatile alkaline nitrogenous substances, volatile sulfides, carbonyl compounds, and so on.

Saltwater fish contain a lot of fresh-smelling oxidized trimethylamine, which is easily reduced to trimethylamine by microorganisms and enzymes after the fish dies.

Trimethylamine is completely different from oxidized trimethylamine, which not only makes the fish lose its fresh taste, but also becomes fishy. Oxidative rancidity of fats in the body of the fish also produces carbonyl compounds such as propionaldehyde, butyraldehyde, and glutaraldehyde, which have a fishy odor. But "fishy bone" does not exist, "bone blood" is coagulated blood, should be washed away.

The main component of the black film is natural melanin, which is not directly related to the fishy flavor. Wash off the mucus on the surface of the fish helps to remove the fishy, but at the same time will also wash away part of the fresh flavor material. It is not reasonable to wash the fish with hot water at 80 degrees Celsius, and it can be washed with water at room temperature.
