Description / Abstract:
This International Standard gives guidelines for the
quantitative compositional analysis of milk and liquid milk
products, such as raw milk, processed milk, cream and whey, by
measurement of the absorption of mid-infrared radiation.
Additional built-in instrument features, such as a conductivity
sensor, can improve the performance in the determination of
compositional parameters and allow for the estimation of other
parameters.
The guidelines specified are applicable to the analysis of cow's
milk. The guidelines are also applicable to the analysis of milk of
other species (goat, ewe, buffalo, etc.) and derived liquid milk
products, provided adequate calibrations are generated for each
application and adequate control procedures are in place.
The application is limited to lower viscosity products that can
be pumped through the flow system of the analyser and to analytes
that do not result in optical saturation at the specific
wavelengths being utilized.
