Shrimp how to de-fishy

Thawed shrimp can then begin to de-fish through some of the following methods.

1, remove the black fishy glands

Remove a black fishy gland on the back of the shrimp (probably the shrimp's stomach and intestines).

Fishy glands: fish body on each side of a white line, called "fishy glands", this mucus gland secretion out of the mucus, containing the oxidation of trimethylamine, "trimethylamine oxide" has a certain fresh taste (the fish meat of the freshness of the opposite), but when the fish is dead! However, when the fish dies, the "Trimethylamine Oxide" with fresh taste will be continuously "deoxygenated" and reduced to "Trimethylamine" spreading into the air. The fishy smell we smell is basically the odor of "trimethylamine". Some odors of the external environment, such as the earthy smell of the water is directly attached to the fishy line through small holes. Shrimp also have fishy glands on their bodies for the same reason as fish.

2, soaked in salt water

Shrimp in salt water for two hours can be very good to get rid of the earthy odor.

The principle of salt deodorization is mainly the use of the principle of saline precipitation, coupled with cold water using osmotic pressure. Salt precipitation of salts and the dilution effect of osmotic pressure of crystals is weakened under alkaline conditions and strengthened under acidic conditions.

3, cooking wine / white wine / fruit wine and other alcohol marinade

Wine is an organic solvent that can dissolve and volatilize the fishy substances. So we can sprinkle shrimp with cooking wine or white wine and other marinade for 20 minutes to fishy flavor. Because fish and shrimp fishy mostly trimethylamine, and wine contains alcohol, alcohol can well dissolve trimethylamine. Moreover, cooking at higher temperatures, alcohol, trimethylamine all easy to volatilize, so not a moment, the fishy flavor is removed.
