Beer is a complex mixture of various types of macromolecules including proteins and polysaccharides. There is an increasing demand for in-depth and accurate analysis of the macromolecules in beer. Macromolecules in beer are derived as a result of brewing that involves various modifications of proteins and polysaccharides of barley seeds. It is known that properties of proteinaceous molecules are related to the mechanism of formation and foam stability. Presence of some proteinaceous molecules results in a formation of haze. The presence of polysaccharides with high molar mass tends to increase viscosity and turbidity of beer. In this study, three types of beer were prepared using the mashing process. The capability of FlFFF coupledd online with multiangle light scattering (FlFFF-MALS) for determination of molar mass distributioni and quantitative analysis of macromolecules in beers were investigated. Also the beer components were identified by enzymatic treatment. The results reveal that FlFFF-MALS may become a useful tool for monitoring of the change in the macromolecular composition of beer during the mashing processes.
