A cryoscopy is used to test for what in milk?

• A. Fat content
• B. Added water
• C. Protein levels
• D. Microbial contamination

Answer: (B)

A cryoscopy is a technique utilized to determine the freezing point of a liquid, and this method is particularly useful in analyzing milk. The primary purpose of this test is to detect the presence of added water in milk. When water is added to milk, it alters the freezing point, causing it to be higher than the standard threshold established for pure milk. By measuring the freezing point, one can infer if water has been added, indicating potential dilution or contamination issues. Thus, the cryoscopy effectively helps ensure the quality and authenticity of milk by identifying any adulteration with water.
