A layer of silver white material on the surface of hairtail is often mistaken for the scales of hairtail, and it is said that it has a strong smell, so it is always washed off by all means before cooking.

Chen Peiyi, director of the Capital Nutrition and Health Food Society, said that in fact, the silvery white substance is not scales, but a kind of fat without fishy smell, which has certain nutritional value. It contains unsaturated fatty acids, lecithin and 6- thioguanine. The silver scales of hairtail can also play a role in making hairtail not easy to break when cooking.

Therefore, when washing hairtail, you should not "scale". Silver scales are afraid of heat and will melt in water at 75℃, so the water temperature should not be too high when cleaning hairtail, and the surface of fish should not be scraped excessively to prevent the loss of silver grease.

However, this silvery white fat is easy to be oxidized and turn yellow after being exposed to air for a long time, and it has a certain "spicy taste". When this happens, it is time to "scale" when washing.
