In terms of taste, frozen fish is inevitably not as fresh as fresh fish. In order to better preserve the fish, it should be frozen at low temperature. Since the shelf life is long, it must be exchanged by other means. Therefore, the taste of frozen fish is not comparable to that of fresh fish, because in the process of freezing, due to low temperature, a series of changes have taken place in fish eggs, and the enzyme activity and gel type of protein have decreased, which is the reason for the decline in taste. Even so, frozen fish tastes quite good.

Second, nutrition.

At present, there is no technology to ensure that frozen fish will not lose nutrition at all during freezing. So there are still some differences in nutrition between frozen fish and fresh fish. But this difference is very small, almost negligible. In the process of freezing, some nutrients of fish will crystallize due to low temperature, and after thawing, this part of nutrients cannot completely return to the fish. This part of the lost nutrition is almost the same as that of fresh fish due to the influence of the environment in the process of buying and selling, so the nutritional value of frozen fish and fresh fish is not very different.

So you can buy frozen fish with confidence, without worrying about whether frozen fish has no nutritional value, because frozen fish has almost no difference in nutritional value except that it tastes worse than fresh fish. The Spring Festival is coming, so let's hurry to stock up the new year's goods.
