Extract

The average freezing point of milk from dairy cows is -543m°H. A lower freezing point depression (FPD) is equated with extraneous water having been added to the milk. The validity of the test relies on the basic assumption that the natural variation in the freezing point of milk is small. Milk with a FPD of -530m°H is legally acceptable in the UK. However, average milk ex-farm has a FPD of -545m°H, encouraging those seeking higher milk quality to suggest a more stringent legal minimum. This experiment investigated the effects of feeding on FPD.
