Q. Which of the following are used as natural food colorants?
  1. Curcumin
  2. Anthocyanins
  3. Chlorophyll
  4. Neotame
Select the correct option from the codes given below:

Answer: Only 1, 2 & 3
Notes: Curcumin (from turmeric), anthocyanins (found in berries and other colored fruits), and chlorophyll (from green plants) are all natural food colorants. Neotame, however, is a high-intensity artificial sweetener and is not used as a food colorant. Thus, only options 1, 2, and 3 are correct as natural food colorants.
