At 0.08 to 0.80% levels of K2Cr2O7 the milk fat content determined with a Milko-Tester Automatic was not measurably affected by up to 3 days storage at 21-27 degrees C. Official methods recommend 0.21%. A depression of <0.05% in the fat % is detectable by the Milko-Tester Automatic after 3 days of sample storage. Deviations of >0.05% between duplicates, and fat % depressions of >0.1% occurred on and after the 5th day. Storage results on days 7 and 12 were still more unsatisfactory.
