How to buy chilled seafood?

1) Salmon. Choose a darker salmon because it is a deep-sea fish, and the darker the color, the darker the growing position, and the more tender the meat.

2) Yellow croaker. When consumers buy yellow croaker, they can touch the fish maw with their hands, and if it does not fade, it is genuine. In addition, choose a yellow croaker with a natural yellow color and a shiny color, if the color is whitish, it means that it is not fresh.

3) Squid. Press the membrane on the squid, the membrane of the fresh squid is firm and elastic, and you can also pull the head of the squid, the head of the fresh squid is tightly connected to the body and is not easy to tear off. This method can also be used to determine the freshness of cuttlefish.

4) Jellyfish. Choose jellyfish with thick heads and meat. When buying jellyfish, you should choose fan-shaped whole pieces, not broken ones. Jellyfish are usually used cold, because there is a lot of salt on the surface, so they should be soaked in cold water at least 3 times before cutting, each time about 10 minutes.

5) Frozen shrimp. Mature shrimp with a full body should be selected. The color of the shrimp should be light red, and white shrimp should not be chosen. The shrimp are white, indicating that they have been left for too long or that chemicals have been added to their preparation.

1. When buying frozen marine fish, you should pay attention to the eyes, maw and scales of the fish. Frozen sea fish with clear and bright eyes, intact belly, and intact scales are relatively fresh. Eyes of stale frozen marine fish tend to become cloudy and collapse due to too long of stock or air drying, and the fish belly will also be damaged due to the deterioration of the fish body.

2. When buying saury and yellow croaker, you should also pay attention to the color of the fish body, and the saury should be silvery-white, and the yellow-white yellow croaker with a yellow-white body is fresher. If you can see the gills of frozen sea fish, you can also identify their freshness, such as black or whitish gills, or excessively bright red, they may not be fresh, and the gills of fresh frozen sea fish should be naturally dark red.

3. Fresh hairtail is silver-gray and shiny, but some hairtail fish have a layer of yellow substance attached to the silver-white luster. When buying hairtail, try not to buy yellowish hairtail.

4. Green shrimp: transparent cyan is fresher. For frozen green shrimp, the shrimp body and shrimp are transparent and green, which is relatively fresh, while the non-fresh ones are mostly manifested as the color of the shrimp head is black and the shrimp neck is easy to break and disjoint.

Some wild frozen shrimp should be transparent and pale pink in color, but if the color is too pink, it is likely that the pigment has been added. In addition, the shrimp are too obese and are likely to be soaked in the potion.

5. Sea crab: the limbs must be complete. When buying crabs, you should choose individuals with intact limbs, and light crabs with frozen crab shell meat fullness of less than 80%, tough and dry meat, and broken shells are all defective products.
