Automated Analysis of Total Polyphenols in Beer. R. B. Roy, Technicon Industrial Systems, Tarrytown, NY 10591. J. Am. Soc. Brew. Chem. 44:0171, 1986.

Total polyphenols in several beer samples were determined using automated procedures, and the results obtained were compared with the ASBC method for total polyphenols. The automated method provided slightly lower polyphenol readings; however, the correlation coefficient between the two methods was 0.988. The automated method required minimal instrument set-up, standardization, and sample preparation, and used stable reagents. The automated procedure can analyze up to 40 samples per hour.
