TURBIDIMETRIC METHOD FOR MILK FAT DETERMINATION

For a dispersion of uniform particles, the maximum turbidity obtained when varying the wavelength may be used as a criterion for the volumetric content of the dispersed phase. It had been argued that this principle could be used for estimating the fat content of milk. In trials on unaltered milks from individual cows this method proved fairly accurate, but changes in the fat dispersion were found to have a pronounced influence on the results. Therefore, the method cannot be recommended as a fat test.
