What is INS 100?

INS 100 is curcumin, the bright yellow-orange pigment from turmeric (Curcuma longa). On packs it is used as a natural food colour, often where brands want to avoid synthetic dyes.

Why brands add it

Brands use it because it gives a warm yellow shade that suits Indian palettes, is recognised as natural by consumers, and works across dairy, savoury, and bakery products. It is one of the few colours on Indian packs that comes from a familiar kitchen ingredient.

Where you'll find it

INS 100 commonly shows up on Indian packets in these categories:

  • flavoured milk and lassi
  • ghee and butter
  • ice creams and kulfi
  • savoury snacks and namkeen
  • instant noodles seasoning
  • ready-to-eat curries
  • biscuits and bakery

Veg or non-veg? - Vegan

Curcumin is extracted from turmeric rhizomes by solvent extraction. No animal product is used in its manufacture.
