The Use of the Brabender Semi-Automatic Moisture Tester for the Determination of Total Solids in Milk^1,2

Dairy Industry Section, Iowa Agricultural Experiment Station, Ames

ABSTRACT

A check of the use of the Brabender tester for determination of total solids in milk indicated that the optima among the conditions studied were: A 10-g. sample weight, 110° C. drying temperature, and 3.0 hr. drying time.

The values for total solids obtained by this method were significantly lower than those by the A.O.A.C. procedure (mean A.O.A.C.-mean Brabender= 0.19%).

The variations among the replicate determinations of the same sample of milk were least by the Brabender, greatest by the A.O.A.C. and intermediate by the Mojonnier method.

There was no significant difference between the mean determinations by the Mojonnier and A.O.A.C. procedures.
