Fish is more delicious, tender and nutritious than cattle, sheep and pork. It is a good source of protein and minerals! Fish has high nutritional value. Fish is not only low in fat, only half as many calories as pork, but also high in sodium, which helps to maintain mineral balance. Then, since fish has so many benefits, why don't some people like it? In fact, the reason is very simple. Besides being allergic to fish, most people don't like to eat fish because of its fishy smell. Today, I will share with you some skills to remove fishy smell, so that everyone can eat fish with no fishy smell but fishy smell.

Why do fish smell like fish? To know how to remove fishy smell, we must first understand why fish smells fishy. The fishy smell of freshwater fish and marine fish comes from different sources. Freshwater fish mainly grow in rivers, lakes and ponds, where there are many microorganisms and algae. When freshwater fish breathe through gills and eat algae, they inhale actinomycetes. These actinomycetes attach to fish or enter the metabolism of fish, forming an earthy smell. In order to resist the osmotic pressure of seawater, the cells in marine fish are full of amines and amino acids, among which trimethylamine oxide is the main source of fishy smell. After the death of marine fish, tasteless trimethylamine oxide was reduced to trimethylamine by bacteria and enzymes, which had a strong fishy smell.

Tips for removing fishy smell: Now that we know the reason of fishy smell, here are some tips for removing fishy smell. Try to choose fresh marine fish. This seems to be nonsense, but it is not the case. The smell of marine fish is much smaller than that of freshwater fish. If you are afraid of the smell of fish, it is strongly recommended that you choose marine fish. Freshwater fish will still have a little taste no matter how deodorized. The other is to choose fresh fish, which will taste much less.

Many people know that cooking wine can remove fishy smell and enhance fragrance, but they don't know why it has this function, so the timing of cooking wine is wrong, or it was accidentally put in when cooking. Cooking wine can remove fishy smell because the raw materials of cooking wine are composed of rice wine, water and some additives. The ethanol in rice wine can volatilize with trimethylamine during cooking, thus taking away the fishy smell. Moreover, cooking wine also contains monosodium glutamate (the main component of monosodium glutamate), so it can play a role in enhancing freshness. Before cooking fish, spread cooking wine evenly on the fish before cooking. With the increase of temperature, ethanol volatilizes fishy substances, which can remove fishy smell and enhance fragrance.
