When buying prawns, if you see these signs, avoid them immediately. Even if it’s cheap, don’t buy it!

To buy delicious and fresh prawns, you need to have a tip but not everyone knows it.

1. Notice the heads and tails of prawns

When buying prawns, if you pay close attention, you will see that some prawns have black heads and tails. The enzyme reaction is the reason why prawns turn black. This often occurs when prawns are exposed to high temperatures, lack of oxygen or some other causes. Therefore, if you see the prawns’ head and tail turn black, it means that the prawn has been left for a long time and shows signs of spoilage, it is best to avoid it.
