ResumoIn the determination of aldehyde values of slightly oxidized butterfat samples by Schibsted's method, the colour of the butterfat prevents accurate matching with the colour standard. Interference by butterfat colour is eliminated, and more accurate results are obtained if the colour is measured in a photoelectric colorimeter at a wavelength of 510 m µ . A small constant correction for the absorption by butterfat at this wave-length may be made.
