Can the oil used to fry fish still be used?

The oil used to fry fish can generally be used without causing any problems.

The oil used to fry fish may have some fishy smell and can generally be used for frying fish next time. If it can be used normally after removing the fishy smell, the fishy smell is mainly removed by using onions, because the oil used to fry fish contains trimethylamine, which is the main source of the fishy smell, and onions can play a volatile role and can also absorb the fishy smell in the fish oil. In addition, the oil used to fry fish must be stored correctly and must be used up as soon as possible, because used oil will accelerate the oxidation reaction. If it is not used up as soon as possible, it may cause the oil to deteriorate, which is not good for your health. At the same time, fried oil generally cannot be heated at high temperature again, because the fatty acids in the fried oil will be destroyed, and heating it again will cause the fatty acid destruction to worsen.

You must be careful when eating cooking oil. You cannot use only one type of cooking oil for a long time. You should also avoid using vegetable or animal cooking oils frequently. People with high blood lipids must control their intake when using cooking oil. We must develop good living habits or eating habits in our daily lives. We need to eat more vegetables or fruits, and we can also eat more meat or soy products.
