Children have been eating cod, but recently, real and fake cod have been making a lot of noise. I don't know how to buy it. Who knows the difference between real cod and oily fish and how to distinguish between real and fake cod? urgent 1, look at the cross section: the color of the silver cod meat is white, and there is no particularly thick and obvious red line on the meat; Fish scales are very dense, as long as one piece is pressed. The big cross section is real cod, and the small cross section may be oily fish. This is because cod is bigger than oily fish. There will be a yellowish or reddish line in the middle of the oily fish, but the real cod does not.

2. Look at the color of meat and skin: the skin of cod is white or gray, with light color and delicate meat; The skin of oil fish is gray-black, dark and reticulate, and the meat is hard and rough. The meat of real cod is whiter than that of oily fish, which will be yellow after careful look.

3, look at the scales: silver cod scales are smaller, with small silver dots on the body, and the meat color is lighter. The scales of cod are very sharp and feel like needles. In order to reflect this "noble" feature of real cod, stores generally do not peel off their scales. However, the scales of oil fish do not have this feature.

4. Touch by hand: After thawing, the real cod will feel very smooth. After thawing, touching the skin of the fish, the silver cod has a smooth feel like a mucus film, while the oily fish is relatively rough; Generally speaking, when silver cod is sold, it is not scraped.

5, taste: Silver cod is a deep-sea fish, which melts in the mouth, and the meat is very delicate. It can be eaten raw with horseradish like salmon, with a unique fragrance and umami. The taste is like crab leg meat, which is more muscular; Oil-fried fish has a meat flavor after being cooked in oil, and it tastes very greasy. After being cooked, the meat quality is very thick and the taste is poor.
