How to remove the fishy smell of Shrimp
Frozen shrimps are best thawed naturally
Most of the shrimps bought are frozen shrimps on the market. The smell of frozen shrimps is more serious. Remember, it's better to thaw naturally, don't put microwave oven heating, so carelessly overheat, shrimp become pink, half-cooked, how to fry is not delicious. If you want to thaw fast, you can wash it in cool water. Don't use warm water, let alone hot water. The meat on the surface of shrimps will be fragile, more fishy, and not crisp and tender.
How to Deodorize Shrimp
After thawing, shrimps can begin to deodorize in one of the following ways.
1. Remove the black fishy glands
Remove a black fishy gland (probably the stomach and intestine) from the back of the shrimp.
Fish gland: There is a white line on both sides of the fish body, called "fishy gland". The mucus secreted by this mucous gland contains trimethylamine oxide. Trimethylamine oxide has a certain delicious taste (contrary to the delicious fish), but when the fish dies, the delicious "trimethylamine oxide" will continue to "deoxygenate". Reduction into "trimethylamine" diffuses into the air, the smell we smell is basically "trimethylamine" odor. Some odors of the external environment, such as the earthy odor in water, are directly attached to the fishy line through small holes. Shrimp has fishy glands on its body, the same as fish.
2. Salt water immersion
Soak shrimps in salt water for two hours to remove the earthy smell.
The principle of deodorizing salt is mainly based on the principle of salting out, coupled with cold water using osmotic pressure. Salting out of salts and dilution of osmotic pressure of crystals weaken in alkaline condition and strengthen in acidic condition.
3. Pickling of Liquor/Liquor/Fruit Wine
Wine is an organic solvent, which can dissolve and volatilize odorous substances. So we can sprinkle shrimps with wine or liquor and marinate them for 20 minutes to remove the fishy smell. Because the fishy smell of fish and shrimp is mostly trimethylamine, and the wine contains alcohol, alcohol can dissolve trimethylamine well. Moreover, when cooking, the temperature is higher, alcohol and trimethylamine are easy to volatilize, so in a short time, the smell is removed.
4. Cinnamon stick
When boiling shrimp in boiling water, put a cinnamon stick in the water, which can eliminate the odor and will not affect the frightening taste.
Cinnamon bars are cinnamon bars, rolled into bars when they are dried in the sun. Most vegetable markets and seasoning stores have them.
5, vinegar
When cooking shrimps, adding vinegar can dissolve the fishy smell. Because the fishy smell of fish and shrimp belongs to amines, which are weak alkaline, while acetic acid and alkaline amines in vinegar can combine to form neutral salts, thus reducing the fishy smell.
6. Scallion, Ginger and Garlic
When cooking shrimps, add some onion, ginger and garlic, because they are rich in allicin (also known as allicin) and propylene sulfide, which can remove fishy smell and increase aroma.
7. Orange peel
Orange peel contains a large amount of vitamin C and essential oil. When making shrimp soup and other dishes, a little orange peel and pomelo peel (Qie Xiaokuai) can remove the fishy smell and the delicate smell of the peel.
