CA 2178627

The present invention relates to a method for quantitatively assessing the amount of any extraneous water contained in a milk sample, the method comprising the steps of (a) performing a determination of the infrared (IR) attenuation of the sample in at least one waveband, (b) quantitatively assessing the amount of any extraneous water in the sample on the basis of the determination (a) and predetermined regression coefficients derived from multivariate calibration with respect to the relationship between infrared attenuation in the at least one waveband and the amount of extraneous water. The invention furthermore relates to a similar method for determining the freezing point depression of the sample. In addition, the invention relates to a method for the establishment of a set of regression coefficients for use in an instrument which determines the amount of extraneous water or the freezing point depression of a milk sample.

L'invention concerne un procédé qui permet d'évaluer la quantité d'eau étrangère contenue dans un échantillon de lait. Ce procédé consiste à: a) déterminer l'atténuation de cet échantillon dans l'infrarouge, dans une longueur d'onde au moins; b) évaluer la quantité d'eau étrangère dans cet échantillon en fonction de la détermination précédente et de coefficients de régression prédéterminés dérivés d'un étalonnage à plusieurs variables concernant la relation entre l'atténuation infrarouge, dans cette bande au moins, et la quantité d'eau étrangère. L'invention concerne aussi un procédé similaire permettant de déterminer l'abaissement du point de congélation de cet échantillon. L'invention concerne enfin un procédé permettant d'établir une série de coefficients de régression utilisables avec un instrument qui détermine la quantité d'eau étrangère ou l'abaissement du point de congélation propre à un échantillon de lait.
