"After a long search for a better way to stop extreme bleeding, the U.S. Army has purchased more than 400,000 bandages made from chitosan, a polysaccharide extracted from the exoskeletons of Icelandic shrimp."Another cool thing about Chitosan: it's a carbohydrate, so people that are allergic to shrimp can use it, since the proteins are the culprit of a histamine reaction. link
dude - those shrimps look like the 'sakuraebi' that's used for okonomiyaki. I love them things. Good in yakimashi too. Shit....Now I'm hungry.
I remember that your fingers used to get all red and itchy when you shelled shrimp for tempura, which is a sign for an allergic reaction. Does this mean that you can't be exposed to chitosan products?
