Under the National Iodine Deficiency Disorders Control Programme, iodised salt in India must contain a minimum of how many parts per million (ppm) of iodine at the production level?
- A 15 ppm
- B 20 ppm
- C 30 ppm ✓
- D 50 ppm
Correct answer: C. 30 ppm
Explanation
Indian standards under the Prevention of Food Adulteration Act require iodised salt to contain not less than 30 ppm of iodine at the manufacturing or production level. The higher value at production accounts for losses of iodine during transport, storage and cooking, so that salt reaching the consumer still contains at least 15 ppm. The 15 ppm figure applies at the household level, not at production.
