text: As other have said, plasma in dried form is a straw or amber colour.\n\nIt does NOT exist as flakes. The proteins and salts in plasma ensure that it dries as a crystalline solid. In terms of everyday objects it looks more like brown sugar than anything else.\n\n\nYou have probably seen dry plasma. If you have ever had a graze or carpet burns you will probably have noticed amber coloured crystals forming a crust at the edge of the wound. That is \nessentially dried plasma escaping from the damaged capillaries.
