The reaction o f oxyamylose with o-phenylenediamine (OPD) in alkaline media produces quinoxalines which can be followed by polarographic method and the dialdehyde content can easily be determined polarographically. The lower limit of the determination of dialdehyde content may be 0.01 in the ratio o
