Lobsters and crabs have a pigment called astaxanthin in their shells, which has the ability to absorb blue light, making the shell appear red under certain conditions. When the lobster is alive, the pigment is safely stored inside a membrane hidden in the shell called the crustacyanin.
What colour are lobsters when they are alive?
When alive and living in the sea, lobsters are naturally a dark-blue/black colour. It is thought that natural selection led to this as it makes them harder to spot for predators.
Most lobsters are a mottled brown color, but sometimes you can see a strange orange or blue lobster. And then, when lobsters are cooked, they turn bright red.
What colour is a raw lobster?
Raw lobsters get their distinctive blue-purplish colour from a pigment called astaxanthin. The pigment molecules are pinkish-orange in their free, unbound form, but when they bind to a protein in the lobster’s shell, their shape and light-absorbing properties are distorted. As a result, they appear blue.
Into the pot When lobsters are heated to high temperatures ” whether they’re boiled, baked or grilled ” crustacyanin lets go of astaxanthin, allowing the pigment to untwist and show its true color. As the lobster is heated, the crustacyanin molecules lose their shape and reorganize in different ways, Cianci said.
Are red lobsters rare?
Around one in ten million lobsters are naturally red before cooking. Apparently these lobsters aren’t actually mutants. They are the same as blue and yellow lobsters, but they just have more red pigment.
Why do lobsters turn red?
Lobsters and crabs have a pigment called astaxanthin in their shells, which has the ability to absorb blue light, making the shell appear red under certain conditions. When the lobster is alive, the pigment is safely stored inside a membrane hidden in the shell called the crustacyanin.

Why do lobsters turn orange?
In lobsters, crab, and shrimp, however, a pigment called “astaxanthin” lies hidden, camouflaged by a protein covering. Astaxanthin is a member of the carotene family of pigments, which are responsible for coloring many of the yellow and orange (or “carotene”) fruits and vegetables.
What is the rarest color of lobster?

Why is my blue lobster turning red?
A relatively simple explanation for the color change emerged in a study published in 2002: Heat changes the shape of a protein called beta-crustacyanin in the shell, relaxing its bonds with the pigment astaxanthin. The freed pigment reflects wavelengths of light in the red spectrum.

What lobsters are red?
They get their shell color from a class of red and yellow pigments called astaxanthin. Without getting too scientific, when lobsters are cooked, the proteins that astaxanthin bind to are destroyed, changing the shell colors to a red pigment. That’s why so many people think Maine lobster is naturally red.
Are Rainbow lobsters real?

Answer: When many lobsters turn black during/after cooking, I tend to think that they were improperly cooked. When the internal temperature during cooking doesn’t reach a certain level, the enzyme ‘phenoloxidase’ can get activated, resulting in the deposition of melanin, or black pigment.
