ABSTRACT
Conclusions:
The modified spot plate test gives consistent results and isa relatively simple test to perform with only the minimum ofequipment necessary.
The centrifuge test gives a high degreeof accuracy and replicability.It requires more equipment andtime to perform than the modifiedspot plate test but the necessaryequipment is readily availablein a dairy testing laboratory.
From the standpoint of accuracy, the subcommittee believesthatthe centrifuge test is the better test to use; however,froma practical viewpoint, the subcommittee feels that themodifiedspot plate technique can be used for most routine testingbecauseof its simplicity and because its degree of accuracyis fairlygood.
