Why are frozen shrimps so crispy and chewy?

Frozen shrimps are very crisp and chewy because the cells of fresh shrimps lose water after being frozen. The loss of water will change the protein structure of the shrimps, and the taste will change. It may also be because the shrimps themselves have been fermented with alkali, and the protein structure changes, causing the taste change.

During the process of alkali-soaking the shrimps, ice and alkali are added to a special mixer, and then it is rotated at high speed to allow the shrimps to absorb the ice water and alkali to achieve the requirements of fullness and elasticity.

If it is not excessive, it is harmless to the body. However, if it is abused, the texture and taste of the shrimp will deteriorate. When frying, the bottom of the pan will become sticky like water starch.

The shrimp meat contains a lot of protein and carbohydrates. The shrimp skin contains astaxanthin, calcium, phosphorus, potassium and other nutrients needed by the human body.

In fact, refrigeration is not easy to change the nutritional elements of shrimp. The most important function of refrigeration is that fresh-keeping and freezing can also slow down the dissolution rate of food by microorganisms.
