Decoding the Codes on Your Food Pack
Those three-digit numbers you see on food labels are part of the International Numbering System (INS) for Food Additives. Developed by the global Codex Alimentarius Commission, this system provides a standardised way to identify food additives worldwide.
In India, the Food Safety and Standards Authority of India (FSSAI) mandates their use. Think of an INS number as a unique ID for a substance. Its purpose isn't to be scary or secretive; it’s to provide a uniform name for an additive that works across different languages and regions. For instance, 'INS 330' is simply citric acid, used to regulate acidity, while 'INS 211' is sodium benzoate, a preservative. Each code is usually listed with its function, such as 'Acidity Regulator (INS 330)' or 'Preservative (INS 211)'. This tells you what the additive does—whether it preserves, colours, thickens, or enhances flavour—but it doesn't tell you anything about its concentration.
Why the Code Itself Doesn't Show Quantity
An INS number is purely an identifier, much like a PAN card number identifies a taxpayer but doesn't reveal their income. The actual amount of any given additive used in a product is governed by separate regulations set by FSSAI. These regulations specify the Maximum Permitted Level (MPL) for each additive in different food categories. For example, the MPL for a preservative in a sauce might be different from its limit in a baked good. Regulators set these limits based on the Acceptable Daily Intake (ADI), ensuring that even with regular consumption, the amount ingested stays well within safe levels. Manufacturers must also follow Good Manufacturing Practice (GMP), which requires them to use the lowest possible level of an additive needed to achieve the desired technical effect, like keeping a product fresh or ensuring a consistent texture. So, while the code identifies the 'what', the 'how much' is controlled behind the scenes by a framework of safety standards.
The Real Story Is in the Ingredient List
If you want to understand the composition of a product, the most powerful tool at your disposal is the ingredient list. In India, as in most parts of the world, ingredients must be listed in descending order by weight. The first ingredient listed is the most prominent one in the product, while the last is present in the smallest amount. This single rule is incredibly revealing. If a packet of 'multigrain' biscuits lists 'refined wheat flour' (maida) as its first ingredient, you know it's primarily a maida biscuit, regardless of the marketing claims on the front. Additives, like those with INS codes, almost always appear at the very end of the list. This tells you that they make up a very small fraction of the product's total weight, which is consistent with their role as functional ingredients used in small, regulated quantities.
How to Be a Smarter Shopper
Instead of getting fixated on the codes, a better approach is to look at the food label holistically. First, scan the top three ingredients; this will tell you what the product is truly made of. If sugar (or its many aliases like glucose syrup, fructose, or maltodextrin), refined flour, or palm oil are at the top, you can make a more informed decision about its nutritional value. Next, look at the nutritional information panel, paying attention to the 'per 100g' column for a fair comparison between products. This gives you a clear picture of the total sugar, fat, and sodium content. The INS codes are just one small part of the story. Recognising that they identify function, not quantity, and that the ingredient list reveals the product's main components, empowers you to see past the marketing on the front of the box and understand what you are actually eating.
