The effect of fermentation period on the accumulation of 55,600 dalton polypeptide was analyzed by SDS-polyacrylamide gel electrophoresis (SDS-PAGE) as a quality parameter of anchovy sauces. Also, proximate compositions, total nitrogen contents, amount of specfic pepited and isoelectric point(pI0 were investigated during fermentation periods. Total nitrogen contents significantly increased until 18 months. Polypeptide of 55,600 and 46,900 dalton on SDS-PAGE and pI 5.2, 5.6 and 6.0 on isoelectric focusing were identified in all the samples. Especially, the amount of 55,600 dalton had no important change during fermentation periods, and it had a high correlation with dilution degree of anchovy sauces diluted with water. The results could be suggest that the amonts of 55,600 dalton polypeptide will be index for quality estimation of commerical anchovy sauces.
