What is generally considered the negative freezing point of milk in degrees Celsius?

The negative freezing point of milk is generally around -0.517 degrees Celsius. This value is important as it reflects the composition of milk and its constituents, primarily water, lactose, and other solutes. In milk, the presence of these components lowers the freezing point compared to pure water, which freezes at 0 degrees Celsius. The freezing point depression is a critical factor in assessing milk quality; deviations from this expected value may indicate adulteration or other quality concerns.

Understanding the freezing point of milk is essential for dairy producers and quality control professionals, as it can be an indicator of the milk's freshness and safety. Knowing that the negative freezing point is not a positive value helps maintain proper quality assurance practices in the dairy industry.
