Polyphenols and important analytic criteria applied to specify the quality of malt.Peer-reviewed article

H. VRTĚLOVÁ, A. DOLEŽALOVÁ

At present much attention is being paid by research workers to the study of polyphenols. Various barley varieties have different concentration of polyphenols, which is not determined only by inherent properties of the variety in question but depends also on many other factors as e.g. soil composition, climatic conditions, growing methods etc. Within certain limits their amount in malt can be controlled by malting technology. Analytic determination of polyphenols is rather difficult. The working group of EBC, formed to study turbidity problems, have chosen from a number of proposed methods one which is both simple and provides reproducible results. It is essentially the Jerumanis-Clerck method which has been appropriately modified and improved.
