Why do shrimps turn black?

After the shrimp die, their internal organs are easily damaged during transportation and squeezing, so the shrimp heads and bodies will turn black after being cooked, or even before they are put into the pot.

In addition, when shrimps are caught, they are fed too much feed and sold on the same day. If the feed is not fully digested, the shrimps will turn black after cooking.

Generally speaking, shrimps will be cooked if boiled at high temperature for one or two minutes. If boiled for more than three minutes, the shrimp internal organs will easily rupture and the shrimps will easily turn black.

In addition, when citizens buy shrimps, they look lively and energetic, but after purchase, the shrimps are usually packed in shopping bags. At this time, the shrimps are in an oxygen-deficient state. When they are put into the pot after arriving home, the activity of many shrimps is already very low, and the shrimp heads are prone to turn black in this state.
