    I need a color-changing paper test (similar to a litmus test) for testing sugar-alcohol. Something small in size, like a small strip of paper. When breath containing 0.17g any of these sugar alcohols (Xylitol, Mannitol, Sorbitol, Glycerol, Erythritol) is blown on strip of paper, it should change color.
