Sample:
First variant
If you've entered for milk analyzer basic freezing point -0.520°C
(according article 5.9 of the EU Milk Hygiene Directive 92/46/ЕЕС),
measured freezing point –0.540°C, using the above pointed formula you'll
receive –3,8%. Because it is not possible the added water to be negative
value, the milk analyzer indicates 0% added water. The reason for this is
the tolerance in the basic freezing point, reasons for which are described
below.
If in the same milk we add 3,8% water, and the basic freezing point
is the same, the milk analyzer will measure freezing point –0.520°C, and
will indicate again 0% added water.
Second variant
If you've entered for the device basic freezing point –0.540°C,
measured freezing point –0.540°C, the milk analyzer will indicate 0%.
When you add 3,8% water, the device will indicate 3,8%-added water.
From the above mentioned follows that it is very important to enter correct
basic freezing point in the device.
The device's results for added water may give information about
doubt of added water in the milk and the exact value of this added water
may be determined after a "cowshed sample" is taken and the result for
the freezing point, measured by the milk analyzer of the "cowshed sample"
is entered as basic freezing point in the formula for calculation of added
water.
Then the result from this formula will give us the absolute value of the
added water for the corresponding milk supplier.
