In order to investigate the content of formaldehyde in fish-paste products, the determination of trace amounts of formaldehyde was studied. After the sample was steam-distilled to 1 l 2,4-dinitrophenylhydrazone derived from formaldehyde was determined by gas chromatography. The recovery of the overall performance of this method was 80.0% for the fortification to kamaboko. The detection limit was 0.05 ppm of formaldehyde. The present method was successfully applied to the analysis of a trace amount of formaldehyde in commercial fish-paste products. The formaldehyde concentrations in tempura, kamaboko and chikuwa were 1.6-9.4 ppm, 1.6-3.6 ppm and 1.1-3.8 ppm, respectively. The sample having the highest concentration, 9.4 ppm, included a fragmentary cuttlefish.
