Polychromatic fluorescent properties of acridine orange solutions were used to characterize wheat tissues and milled wheat products. A water solution of the dye can be used for multicolor staining of wheat tissues. Coloration varies with protein content.A saturated xylol (xylene) solution of the base forms a brilliant fluorescence with the lipid material of either the aleurone or the germ so it can be used to distinguish these two wheat tissues in milled products.
