In milk quality testing, which property describes the thickness or flow characteristics of milk?

Explanation:
Viscosity is the resistance of a liquid to flow, i.e., how thick or thin it is. In milk quality testing, measuring viscosity tells you how the milk behaves during pouring, pumping, and processing. Temperature reduces viscosity, while higher fat and solids can increase it, and processing like homogenization can subtly influence flow properties. A higher viscosity means milk pours more slowly and feels thicker; lower viscosity means it’s runnier. The other properties describe appearance, acidity (pH), or foam behavior, not how milk flows, so they don’t capture thickness or flow characteristics.
