What is the freezing point of milk?(a) 0 °C(b) -0.55 °C(c) -1 °C(d) -1.55 °CThe question was posed to me in homework.This is a very interesting question from Milk Reception in chapter Collection and Reception of Milk of Dairy Engineering

Answer»

The CORRECT choice is (B) -0.55 °C

The explanation: MILK that has been watered down contains more water and less solutes, so its freezing point is closer to 0 °C. Most milk processors will conclude that milk has been watered down if the freezing point is anywhere above -0.55 °C.
