The orange color of the gland comes from a pigment called astaxanthin, which is produced by the microorganisms that the crab consumes.
Where is the substance found in crabs?

Is the orange substance safe to eat?
The orange substance is safe to eat, but it is recommended to consume it in moderation. The substance can contain high levels of cholesterol and other contaminants, depending on the crab’s habitat and diet. People with shellfish allergies should also avoid consuming the orange substance.

Nutritional value of the orange substance
The orange substance is rich in vitamins, minerals, and healthy fats. It is a good source of vitamin B12, selenium, and omega-3 fatty acids. However, as mentioned earlier, it can also contain high levels of cholesterol and other contaminants, so it should be consumed in moderation.
