In fact, the color of shrimp skin is only white and light red. Are you surprised to see this? Obviously I mentioned other colors above. Why is there only light red here? In fact, the yellow shrimp skin comes from the white shrimp skin. White shrimp skin contains less astaxanthin, which is mostly produced in Bohai Sea area and tastes slightly salty. If left for a long time, it will gradually turn pale yellow.

The same is true of deep purple shrimp skin, which is made of light red shrimp skin and slowly changes color, with little change in essence. The content of astaxanthin in light red shrimp skin is high, mostly in the East China Sea. So when selling shrimp skins, we can easily tell their freshness by color.

Second: Different nutrition.

The white shrimp skin will be relatively small. Although its astaxanthin content is low, its calcium content is high. If you are a friend who wants to supplement calcium, you must choose white shrimp skin. Similarly, the light red shrimp skin has a high content of astaxanthin, so it tastes better than the white shrimp skin. If you want to choose dumpling stuffing, light red shrimp skin will be your best choice.

Shrimp skin tastes delicious and has high nutritional value, but different colors of shrimp skin have different nutritional components, and different freshness presents different colors.
