SUMMARY— The method developed for total anthocyanin determination involves the measurement of the absorbance at 510 nm on samples diluted with pH 1.0 and 4.5 buffers. The pigment content is calculated in absolute quantities with the aid of extinction coefficients established for the cranberry anthocyanins dissolved in the buffers. An index of anthocyanin degradation, based on a new concept, could be calculated from the measurements obtained for the total anthocyanin determinations.
