First, it is best to rinse the shrimps with clear water before soaking them, which can make them cleaner and more hygienic. Remember to use warm water when soaking shrimp in warm water. Too high water temperature will destroy the tissue of shrimp meat, and too low water temperature will take a long time and have poor effect. Add a little edible salt to the prepared warm water. After the edible salt is completely dissolved, soak the dried shrimps in warm water 10- 15 minutes.

Second, how to distinguish the quality of shrimp skin?

The first step is to identify the freshness of shrimp before buying it. The fake shrimp looks chubby and transparent, and its color is milky white. It feels elastic when touched by hand, but it has no shrimp flavor at all. The real shrimp is light gray in color, soft and elastic, full of touch and rich in shrimp flavor.

Second, the price is also a criterion for considering good or bad. When buying shrimp, don't blindly pursue cheap prices. Cheap products are not necessarily good. The price of vacuum-packed shrimp in the market ranges from tens to hundreds of yuan. Imported shrimp is more expensive than domestic shrimp!

Third, the nutritional value of shrimp skin.

There are two kinds of shrimps, and fresh shrimps are not easy to preserve, so people often like to buy some shrimps and put them at home, and eat them whenever they want. Shrimp is soft and easy to digest after soaking, which is a delicious food in Xian Yi and Xian Yi. So what nutrition does shrimp have?

1. Shrimp skin is rich in magnesium, which plays an important role in regulating heart activity and protecting cardiovascular system. It can reduce the cholesterol content in blood, prevent arteriosclerosis, dilate coronary artery, and help to prevent hypertension and myocardial infarction.

Second, the protein content of shrimp is high. Every 100g of shrimp contains protein 10.40g, which is several times or even dozens of times that of milk, eggs and fish.

Thirdly, shrimp contains a very effective antioxidant, namely astaxanthin, which can not only resist aging, but also eliminate jet lag.
