Can you tell me how to extract chitin from crab shells?
You have to grind up the shells and remove the calcium, perhaps using ACV (apple cider vinegar). I remember an old trick where you could place a whole egg (shell and all) in a glass milk bottle by soaking the egg in vinegar to soften the shell. Egg shells also use chitin. But see the source for details. Good luck.
