Blue Crab Turns Red Crab – Science 22

Fish, shrimp and crawfish are our favorite items when we buy seafood in the market. They mainly harvest from our state waters.

At least two kinds of crabs are sold in our areas, blue crabs (Callinectes sapidus) and Dungeness (Metacarcinus sp). The Dungeness crab has been posted previously:

I believe you know that all crab and lobster will turn red when cooked by boiling or steaming it.

The question then: Why?

Image 3- Crab turns red when we cook it.

As you might know, the process of crab, prawn, lobster or crustaceans turns red when cooked:

- first, heat due to grilling or boiling will destroy protein called crustacyanin.
- second, releasing of astaxanthin
- finally, shell turns red (bright red).

Many people love to consume crustaceans, but few people don’t like them because of many reasons.

Some of my friends have allergic if they eat crustaceans.

How about you? Do you like to eat lobster, crab or shrimp?

  2. Si me gustan todos los crustraceos pero no los consumo con frecuencia.
    Siento decirlo pero es así, me ha resultado muy complicado y he perdido mucho tiempo con un tema corto y fácil, como consecuencia de la inserción de tres anuncios. Saludos cordiales y que tengas mucho éxito con tus inserciones de anuncios. Todo mi respeto para quien tiene que buscar alguna forma de ganarse la vida.

  6. It is interesting how crustaceans change color when cooked. I never ate seafood so I have no idea what it tastes like. It has always creeped me out how a whole animal is on a plate and a person mutilates, then eats it.
