The objective of the research was to analyze the possibility of application the chitosan in combination with other commonly used beer stabilizers. The following kinds of chitosan have been used during the analysis: low-viscous chitosan additionally powdered, water rinsed chitosan, activated with kalium pyrosulfite, Polyclar R, Stabifix Super and combinations of chitosan with Polyclare and Stabifix. The water rinsed chitosan has slightly decreased acidity of the beer, activated chitosan has not produced such a result. The use of chitosan in combination with limited dosages of Polyclar and Stabifix has given the stabilization effect similar to standard dosages of these mixtures. Adding of chitosan has not changed the composition of alkaline elements of beer. Application of chitosan in combination with traditionally used mixtures may reduce the costs of production of beer.
