How do you tell whether salmon is new or not?

The first option: buy a whole salmon

1. First check whether the skin and scales are complete and shiny. Intact, with bright silver fish scales, translucent and shiny.

2. Look at the fish eyes. The fish eyes should be clear and not turbid.

3. Open the gills and see that fresh salmon is bright red in color and has red mucus on the gills. The structure is clear and not confusing, and the taste is a light ocean smell rather than a fishy smell.

4. Fresh salmon should be elastic when pressed with your fingers. Salmon that does not return to its original shape immediately after being pressed is a sign of staleness.

5. It is best to choose chilled salmon that arrives at the market on the same day, because repeated thawing and refreezing will affect the taste of the fish.

The second type: buy processed salmon

In Chinese supermarkets, most of what we buy is processed and has been cut into sections or pieces for sale. , which facilitates processing and storage. For this kind:

1. Look at the color first. Fresh salmon pieces are orange-red. If the color is white or dark, and the color is uneven, it means it is not fresh.

2. Fresh salmon meat will be elastic to the touch and will slowly recover when pressed. Stale salmon will not be elastic to the touch and will not return to its original shape immediately.

3. The surface of salmon meat should be moist, not dry. Moisture content is an important indicator of the freshness of salmon.

4. If you see brown spots on the edge or surface of the fish, you must not buy it. This is not fresh.

5. Look at the color of the meat. If it is fresh, you can see an obvious fat line. If the salmon is stale, the fat line will become lighter or even absent.

6. Cut it with a knife and check whether the edge is smooth and whether there is any fishy smell.
