Is rush testing available?
Sample are extracted by homogenization with acidic methanol. Separate aliquots of the extracted samples are diluted with 0.025 M KCl, pH 1.0 buffer or 0.4 M Sodium Acetate, pH 4.5 buffer. Absorbances are read at 520 and 700 nm to determine the anthocyanin concentration (in solution) in cyaniding-3-glucoside equivalents.
C3GE = Cyanidin-3-glucoside Equivalents
