Determination of dietary fiber contents in some Korean foods was attempted by Englyst´s gas chromatographic and colorimetric methods which measure the nonstarch polysaccharide (NSP) contents. NSP values, except seaweeds, by gas chromatography (x) and colorimetry (y) were very closely correlated (y=1.01x-0.52, r=0.997, n=9). NSP values by gas chromatography were lower than total dietary fiber (TDF) values by AOAC method. By adding lignin to NSP values, relation between the two methods was improved. But, TDF values (y) by adding lignin to NSP values and TDF values (x) by AOAC method were related as y=0.68x-0.64 and r=0.903(n=12), which was not closely related.
