What is the average specific gravity of normal whole milk at 16 °C?(a) 0.903(b) 1.032(c) 1.582(d) 2.032I have been asked this question by my college professor while I was bunking the class.The doubt is from Milk Reception in section Collection and Reception of Milk of Dairy Engineering

Answer»

The correct ANSWER is (b) 1.032

Explanation: The SPECIFIC GRAVITY of milk MEASURED at 15^oC or 20^oC is normally 1.028 – 1,033 kg/litre. The specific gravity depends on the protein and fat content. The specific gravity of fat is 0.93, solids-non-fat, 1.6 and water 1.0 kg/litre.
