11 Jan Frozen fish may be better than fresh one
Obviously, the ideal would be to enjoy a freshly caught fish, but it is not always possible. However, frozen fish is much better than most people think.
It is known that fresh fish is much more nutritious than frozen fish, because there are vitamins that are destroyed during freezing, which could lead us to think that frozen fish is bad, but nothing could be further from the truth.
The normal process is to the fish to be been frozen directly in the fishing boat, and that is why it conserves its nutrients to the maximum.
In Spain, 80% of the fish consumed is fresh, this statistic reveals strong consumers’ doubts when buying frozen fish.
Only 2 out of every 10 kilos of fish we eat is frozen. However, this inertia is not always justified. A priori, a specimen of fresh fish is not necessarily healthier than another frozen. If a specimen with a quality nutritional profile at the time of capture is immediately deep-frozen and maintains the cold chain in all its traceability, when defrosted will show almost the same qualities and health benefits as when it was fresh.
Frozen fish nutritional value
Most of fish nutritional properties can be maintained. When caught, any fish has specific nutritional properties. In the case of hake, for example, contains a high content of protein and vitamins of the B group, and if it is salmon or tuna, omega 3 fatty acids. That amount of unsaturated fats (the good ones), as well as their cardioprotective effect, will remain almost unchanged if the fish is deep-frozen quickly after being caught. If so, its nutritional properties will be almost the same when it reaches the consumer’s table thousands of miles away.
Frozen fish is safe
Freezing not only retains the nutritional properties of the fish and preserves them practically intact; it also prevents the growth and development of bacteria. Therefore, we get increased food safety by putting frozen fish ahead of fresh fish.
Anisakis is one of the best-known health risks associated with fish. This parasite, which lives in fish and can infect humans by causing nausea, vomiting and even intestinal occlusion, does not survive freezing, so eating frozen fish means peace of mind and greater safety.
This does not mean that eating fresh fish is dangerous. However, it is not as safe as frozen fish, since the low temperatures to which the latter is subjected rule out the possibility of the presence of anisakis.
Thanks to the effects of a good freeze, we can eat a healthy and safe fish at any time. However, if it is not thawed correctly, we will spoil this and other advantages of frozen fish. Just as conservation treatment is the responsibility of the fishing and distribution industry, thawing is the responsibility of each consumer. It is important to preserve and thaw the fish so that its nutritional values do not diminish and its taste and texture deteriorate as little as possible.
If your homer freezer has 4 stars, the fish will last for months at -18ºC. Although species such as cod, salmon or pollack, which are very delicate, should not spend more than a month in the freezer.
Now there are no longer reasons to give up fish in your diet. Frozen fish is cheaper than fresh fish, and as you can see it is totally safe. Besides, you already know how to defrost it without losing its properties. Remember that we should eat fish three or four times a week, including an oily fish.
