Freshness of seafood:

Shellfish are more delicate than fish, for this reason you have to take special care when buying them. It must be in a reliable, specialized place with suitable cooling equipment and qualified personnel, which guarantees the quality of the product.

To check the quality of seafood, we need to know that:

They can be purchased live, refrigerated or frozen depending on their class.

The most advisable are the frozen ones due to the guarantee that the cold chain has not been interrupted and they have been protected from dust and excessive manipulation. The best are the bulk packs i.e. in small packets of 1-2 pounds.

Its smell must be mild to seawater, never penetrating odor to ammonia.

Vivid Color, non-opaque glossy.

Shell live molluscs must have it closed or ajar not opened because this means they are dead. The frozen, unopened ajar. After cooking, it must be opened, if it is closed, discard it because it is damaged.

All shellfish can be cooked to be consumed in different preparations, whether breaded, poached or sautéed in butter or in the desired fatty medium.

When you go to buy frozen seafood you should consider: 

  • Observe the expiration or expiration date of the product. Choose the most distant fulfillment. That the date is not clogged or retreaded is to say that it is not altered.
  • Must Observe that the gasket and the labels are in perfect condition, not broken or in bad condition.
  • Check that they are well frozen and that the package does not have frost, because there you see that they have already been partially thawed.
  • Seafood must be bought at the end of the market, so that the “cold chain” of the product is not interrupted. And when you get to your final destination, you immediately freeze.
  • Do not leave a lot of time exposed to heat inside the car, or outside the freezer (because it shortens its lifespan), maximum 30 minutes not to interrupt “the cold chain”, which prevents the proliferation of bacteria that cause disease.

If possible, it must be transported in a thermal bag and away from polluting products such as cleaners, automotive oils or petrol as it absorbs these smells.

Also when you arrive at your destination, place them immediately in the refrigerator or freezer.
