Abstract

The method according to the International Dairy Federation. IDF Standard 26 A: 1993 corresponding to AOAC is currently the reference method for the determination of the water content in milk powder.

It is well introduced and generally accepted.

The method is based on drying of a test portion to constant mass under given conditions. Constant mass is defined in the standard procedure as '.......if the difference in mass between two successful weightings does not exceed 0.5mg'. A following note states additionally: " drying will usually be complete after the first two hours." However, constant mass is a major problem of this method as it is hardly ever achieved. The results are dependent on the relative air humidity in the laboratory and are therefore of poor reproducibility. For this reason a collaborative study on the determination of the water content in milk powder was performed in order to compare the results of alternative methods with those of the IDF method. od.
