Standard Milk Composition

Standard milk contains:

Correct Answer: 4.5% Fat & 8.5% SNF

According to the Prevention of Food Adulteration Act (PFA-1976), Standard milk must contain a minimum of 4.5% Fat and 8.5% SNF (Solid-Not-Fat).

Milk Fat Standards (PFA-1976)

• Skim milk: 0.5% fat
• Double toned milk: 1.5% fat
• Toned milk / Sheep / Goat / Recombined: 3.0% fat
• Cow milk: 3.5% fat
• Standard milk: 4.5% fat
• Buffalo milk: 5.0% fat

SNF Standards (PFA-1976)

• Buffalo / Sheep / Goat / Double toned milk: 9.0% SNF
• Skim milk: 8.7% SNF
• Cow / Toned / Standard / Recombined milk: 8.5% SNF

Standard milk is essentially a mix blended to meet these legal minimums, serving as the baseline market milk grade in India.

Why Other Options Are Wrong

• 5% Fat & 8.5% SNF — that's the standard for Buffalo milk fat, not standard milk.
• 3% Fat & 9% SNF — matches Toned milk fat with Buffalo/Sheep SNF; incorrect combination.
• 5% Fat & 8.7% SNF — no recognized milk category matches this combination.
