Step 1: Understanding the Concept:
Food safety regulations mandate nutritional labeling on prepackaged foods, but grant exemptions to specific categories that provide negligible nutritional value or serve non-nutritive roles.
Step 2: Detailed Explanation:
Under FSSAI (Labelling and Display) Regulations, several products are exempted from displaying a nutrition facts panel because they do not contribute significant calories or macronutrients:
- Table top sweeteners (A): Primarily composed of intense sweeteners with negligible caloric value.
- Salt and salt substitutes (B): Mineral products containing sodium chloride with no macronutrients.
- Chewing gum (C): Non-nutritive confectionery designed to be chewed rather than swallowed.
- Coffee and chicory mixtures (D), plain tea, and whole spices: Products consumed for flavor or aroma with negligible nutritional contributions.
Therefore, all four options (A, B, C, and D) are exempted from mandatory nutritional labeling.
Step 3: Final Answer:
All of the listed options are exempted from mandatory nutritional labeling, corresponding to Option C.
