According to the seafood professionals, crabs are one of the most notorious ingredients and easy to preserve. Dead crabs can still keep their flavors and freshness if you know the right way to do, even if they are dead 3 hours ago.

However, this won’t work if the crabs were caught about 10 hours ago. The quality can’t be saved anymore, even if you use the frozen technique to remove the bacteria and strengthen the quality of the meat inside the crabs. When being frozen at low temperature, it is quite difficult to find out the quality of the same type of seafood. We don’t know whether they are freshly caught or were stored for a couple of days. Therefore, the simplest solution is using the point of a chopstick to poke the belly of the animal so that we can partly find out the freshness of them. However, the accuracy of this way is not proved to be excellently right in most of the time.

Seafood specialists warn that frozen seafood brings along some kinds of dangerous bacteria such as Coliforms, E. Coli… Dead seafood provides favorable conditions for them to develop and multiply quickly.

So as to reserve the quality of seafood such as crabs and shrimps in 3 hours after being caught, we can use some preliminary treatments and then put them into the cold chamber for about 2 hours. This method helps the food to stay dry and cool so as to prevent the activities of harming bacteria in normal environment.

Before using the seafood for cooking, defrost them naturally by using warm towel and wait for the food to restore to its basic state. Normally the temperature of the refrigerator is -4 to 4 degrees. Never use the microwave to defrost the seafood because it can immediately lose the nutritions inside the meat and the elastic quality of the meat.
