How to preserve seafood at lowest cost?

Since ancient times, the nutritional value of seafood and its benefits to humans have made it popular among people all over the world. At the same time, how to transport it to ensure its nutritionality has also received everyone’s attention. Commonly used preservation methods:

  1. Dry transportation. It cools the water to a temperature that suspends the life of the fish and shrimp, then transports it to the destination, then puts the fish and shrimp into the water and they wake up again. However, this technology is only suitable for some seafood, and the preservation time is only 48h.
  2. Water transport. Regularly observe and spray seawater during transportation.
  3. Canvas barrel transport. It can be transported by train, car, carriage or boat. On the way, water is used to supplement the oxygen. The water quality of the water must be treated in advance to avoid accidents. The general journey can be up to 6 days. If you inflate or oxygenate the barrel frequently, the journey will be longer. This method is safe, but the cost of equipment is slightly higher.
  4. Plastic bag packaging and transportation. The freshness of the product cannot be guaranteed, especially when it is hot in summer.
  5. Use ices for free transport. The most economical mode of transportation at present. They can be frozen at same time as they are caught on the board, till transported, sold on the market.

So, will frozen fish be better than fresh fish? Research is different from what you think!

The Norwegian study found that the nutritional value of frozen fish is not different from that of fresh fish. However, the current fishing can only be used for two to three days, and the frozen packaged fish can keep the nutrients for half a year, and the price is also higher. Being close to the people is a better choice.

According to the Daily Mail, Norwegian research firm SINTEF found that frozen fish can provide even better nutritional value than current fishing, as long as there are a few simple principles, and there is no need to worry about bacteria or parasites. Hazard, but the price is relatively low.

SINTEF conducted experiments on different ways of storing fish. It was found that the freshly caught fish was immediately frozen on the fishing boat and maintained at a stable low temperature, which was the best freezing method. According to SINTEF, after such an immediate freezing treatment, the fish’s taste, taste and nutritional value can be maintained for up to ten days after thawing.

That is to say, if the fish can be frozen at the same time as they are caught on the boat, they can effectively extend their shelf life and allow the fish to have fresh fish in the ten days after the freezing of the frozen food. The same taste and nutrition.

A spokesperson for SINTEF said, “I hope that these findings can change people’s perceptions of frozen fish. They are sometimes better than fresh fish.” Therefore, if you buy from a merchant with a good freezing process, save for two months of freezing. The fish will not be worse than the fish that just came ashore yesterday.
