Question

In case of infant food, if the product other than infant milk substitute is claimed to have higher quality protein then the protein efficiency ratio (PER) which shall be:

• A. Minimum 0.8
• B. Minimum 2.5
• C. Maximum 1.0
• D. Minimum 1.5

Hint:

The value 2.5 is the standard reference point for high-quality proteins (like milk casein) in nutritional labeling and regulatory standards.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
The Protein Efficiency Ratio (PER) is a bioassay method that evaluates protein quality by measuring the weight gain of test subjects per gram of protein consumed.

Step 2: Detailed Explanation:
- Under the Food Safety and Standards (Foods for Infant Nutrition) Regulations, strict nutritional and quality standards are set for infant foods.
- If a manufacturer claims that their product contains high-quality protein, the protein must meet a specified standard.
- FSSAI regulations mandate that the Protein Efficiency Ratio (PER) of such high-quality protein claims must be a minimum of 2.5.
- A PER of 2.5 is the standard biological value of reference casein protein, ensuring the infant food provides high-quality essential amino acids for growth.

Step 3: Final Answer
The minimum Protein Efficiency Ratio required for high-quality protein claims in infant food is 2.5.
