7/2/2015 There was a question that keep bugging me. Why after a prawn is cooked it will turn bright orange red color. Today, I finally looked for an answer on the internet. Lobsters, crabs, prawns have exoskeletons. Exoskeleton is an outer hard structure such as shell that provides protection for an organism. The exoskeleton is blue-green or grayish color. It contains a pigment called “astaxanthin”. This pigment is bright orange red in color. When the prawn is raw, astaxanthin is hidden because they are covered by protein chain. However the protein is not stable. Once it is cooked, the protein will be uncoiled under the heat and the protein coating will be destroyed. Thus Astaxanthin will be exposed and changes the color of the prawn to bright orange red.

Lobsters, crabs, prawns Crustaceans have exoskeletons. Exoskeleton which is an outer hard structure such as the shell that to provides protection for an organism. The exoskeleton It is blue-green or grayish in color. However, it contains a pigment called “astaxanthin”. This pigment which is this bright orangey red in color.

When the prawn is raw, Before cooking, the astaxanthin is hidden because as they are covered by a protein chain. However the protein which is not stable in high temperatures. Heat Once it is cooked, the protein will be uncoil under the heat it and the protein coating will ultimately be destroyed. Thus The color of the Astaxanthin is then exposed which we see in the cooked crustacean. will be exposed and changes the color of the prawn to bright orange red.
