What is INS 330?

INS 330 is citric acid, the same sour-tang compound found naturally in lemons, oranges, and other citrus fruits. On packaged foods it is used to control acidity, sharpen flavour, or help keep the product fresh.

Why brands add it

Brands use it because a tiny amount adds tang to drinks and jams, helps preservation by lowering pH, and keeps the colour of cut fruit and tomato products from going dull. It is one of the most common acidulants on Indian packs.

Where you'll find it

INS 330 commonly shows up on Indian packets in these categories:

  • soft drinks
  • fruit juices and squash
  • jams and marmalades
  • ketchup and chutneys
  • instant noodles seasoning
  • sour candies and jellies
  • ice creams and kulfi

Veg or non-veg? - Vegan

Food-grade citric acid today is produced by fermenting sugar with the mould Aspergillus niger. No animal product is used in its manufacture.

FSSAI status and JECFA evaluation

FSSAI: Permitted by FSSAI for specified food categories with category-specific limits, including as an acidity regulator, sequestrant, and flavour enhancer under Schedule I of the FSS (Food Products Standards and Food Additives) Regulations 2011.

JECFA: Group ADI 'not specified' for citric acid and its calcium, potassium, sodium and ammonium salts (17th JECFA, 1973). 'Not specified' is JECFA's safest classification: it means total dietary intake at typical use levels is not considered a hazard.
