anyone thinking that denatured albumen gives a negative result on a protein test, think again. even fully denatured protein went a nice purple when i tested it
if you put it through filter paper it takes ages, and theres several problems:
1 - the filter paper absorbs the solution
2 - there is some water left over from the solution that the albumen has precipitated out of
i can see using a centrifuge might work, remember you get a change in volume when the albumen precipitates out, and there is still the issue of the water remaining from the albumen solution
i still think that a visual method is the easiest and most accurate!!
