> INS 102, commonly known as Tartrazine, is a synthetic yellow food colour found in many packaged foods and drinks, including sweets, soft drinks, snacks, and flavoured yoghurts. This guide explains what Tartrazine is, why manufacturers use it, how to spot it on a food label, and what recognised food safety authorities such as JECFA, EFSA, FSSAI, and the FDA say about its safety, alongside possible side effects for sensitive individuals and how it compares with natural food colours.

If you have ever checked the ingredients list on a packet of sweets, a fizzy drink, or a flavoured yoghurt, you may have come across the term INS 102 or Tartrazine. It is one of the most widely used food colours in the world, yet many shoppers are not entirely sure what it is or whether it is something to worry about.

INS numbers are part of the International Numbering System for food additives, a global reference used to identify additives consistently across countries. INS 102 refers specifically to Tartrazine, a synthetic yellow colour added to many packaged foods and drinks.

In this guide, we will explain what Tartrazine actually is, why manufacturers use it, which foods commonly contain it, what food safety authorities say about its safety, and how you can spot it on a label. We will also look at how a tool like FactsScan can help you understand additives like this one when you are scanning products in the supermarket.
