Popis: The article focuses on the issue of melanoidin quantification and its influence on the color characteristics of brewing products. It is shown that the reaction conditions (100±2)°C, the processing time of 2 hours and a certain list of sugars and amino acids typical for brewing products are adequate to obtain linear dependencies for estimating the beer melanoidin content at 300 and 420 nm. The data on the total content of melanoidins in light beer in the range of 3.83-51.4 mg/dm3, and in dark beer – 6.82-145.94 mg/dm3 at the specified wavelengths are given. The authors found that the dependence between the color and the total beer melanoidin content is characterized by a correlation coefficient R = 0.624, which indicates the influence of other organic compounds of beer on the color intensity.
