Profiling of oligosaccharides and polysaccharides in alcoholic beverages using single quadrupole LC-MS

Simultaneous analysis of oligosaccharides and polysaccharides was achieved using a single quadrupole LC-MS. Up to 36-mer polysaccharides (average molecular weight 5855.09) were detected in beer as the trivalent ion (m/z 1949.63). As the results of principal component analysis and relative comparison, profiling of oligosaccharides and polysaccharides in six types of alcoholic and non-alcoholic beer was successfully performed.
