Step 1: Understanding the Concept:
The Food Safety and Standards Authority of India (FSSAI) sets legal standards for different categories of liquid milk to prevent adulteration and ensure consistent nutritional quality.
Detailed Explanation:
Milk is classified into several commercial grades based on its milk fat and Solids-Not-Fat (SNF) percentages.
Double toned milk is a low-fat milk variant prepared by mixing whole milk, skim milk, or reconstituted skim milk powder with water.
According to FSSAI regulations:
- Double Toned Milk: Must contain a minimum of \(1.5\%\) milk fat and a minimum of \(9.0\%\) Solids-Not-Fat (SNF).
This standard is designed to provide a low-calorie option while maintaining a high protein and mineral content (SNF).
Let us compare this with other common categories to avoid confusion:
- Toned Milk: Minimum of \(3.0\%\) milk fat and \(8.5\%\) SNF.
- Standardized Milk: Minimum of \(4.5\%\) milk fat and \(8.5\%\) SNF.
- Full Cream Milk: Minimum of \(6.0\%\) milk fat and \(9.0\%\) SNF.
The values \(1.5\%\) fat and \(9.0\%\) SNF align with the legal definition of double toned milk.
Step 2: Final Answer:
The correct fat and SNF standard for double toned milk is 1.5% & 9.0%.
