text: what is the colour of human dried plasma, and is the dried plasma a powder or flakes?   as other have said, plasma in dried form is a straw or amber colour.  it 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.   you 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  essentially dried plasma escaping from the damaged capillaries.
