Storage of shrimps: firstly, clean the shrimps with clear water, put them into metal utensils, inject cold water, freeze them in the freezer, take them out after freezing, leave them at room temperature for a period of time, pour out the frozen shrimps, then put them into fresh-keeping bags and store them in the freezer.

Generally, seafood can be stored in the refrigerator for a long time, but cooked shrimp food can not be stored in the refrigerator for too long, which will affect the taste. At the same time, it must be sealed before it can be put into the refrigerator, otherwise it will make the refrigerator full of odor.

Common methods to distinguish whether big lobster is fresh;

1, body bending

Fresh shrimp has a complete head and tail and is closely connected with the body. Shrimp body is quite hard, with certain elasticity and curvature. However, the head and body, shell and meat of aged shrimp are loosely connected, and the head and tail are easy to fall off or separate, which can not maintain its original curvature.

Step 2 dry the body surface

Fresh shrimp looks clean and feels dry. However, when the shrimp body is about to deteriorate, the granular cells secreting mucus in the lower layer of crustaceans disintegrate, and a large amount of mucus penetrates into the body surface, which feels greasy. If the shrimp shell sticks to your hands, it means that the shrimp has gone bad.

3. Bright colors

Different species of shrimp have slightly different colors. Fresh shrimps, rock shrimps and grass shrimps are blue, shrimps caught in the sea are pink, and bamboo shrimps and new shrimps with knife forehead are black and white with a slight pink color. If the shrimp has black hair, it is stale shrimp, and the whole shrimp is dark and not bright, which means it has gone bad.
