Abstract
Beer foam polypeptides have been separated into five groups based on t heir relative hydrophobicity. Foam stability increases with increasing hydrophobicity of the polypeptide groups. The most hydrophobic polype ptide group contains a large proportion of Coomassie blue-binding poly peptides. Analysis by SDS-PAGE reveals that each polypeptide group is composed of several differently-sized polypeptides. Further purificati on by anion-exchange chromatography results in five fractions, each of which has a different polypeptide profile on SDS-polyacrylamide gels.
