MCQ (Single Correct)

Lactometer reading is used to determine

Protein content in milk SNF % in milk Correct Fat % in Milk Viscosity of milk

Determination of Solids-Not-Fat (SNF) via Lactometer Reading:
Analytical Role:
Corrected Lactometer Reading (CLR) measures specific gravity. Combined with Gerber fat percentage, it calculates % SNF (Solids-Not-Fat) using Richmond's equation:

$$\%\text{SNF} = \frac{\text{CLR}}{4} + 0.25 \times \text{Fat} + 0.36$$

Vital rapid platform test for detecting illegal watering down or skimming of market milk supplies.
Conclusion: SNF % in milk (Option 2).

Correct option: (2) SNF % in milk
