INS Numbers Decoded: The Additive Codes on Indian Food Labels You Should Actually Know

First — what even is an INS number?

Think of INS numbers as nicknames for chemicals.

Instead of printing "Monosodium Glutamate" on every packet of Maggi masala, brands just write "INS 621." Instead of "Sodium Benzoate," they write "INS 211." It's shorter, it fits on the label, and — let's be honest — most people won't Google it.

INS stands for International Numbering System. It's a global list of approved food additives maintained by a food standards body called Codex Alimentarius. India's food regulator FSSAI follows this same system.

Not all additives are bad. Some are completely boring and harmless. But a few are worth knowing — especially if they're in something you eat every day.

Let's go through them, one by one, in plain English.

The ones you can completely ignore

INS 330 — Citric Acid

This is lemon sourness in a powder. That's it. It's found naturally in every lime and amla you've ever eaten, and the commercial version is chemically identical. It's used in biscuits, juices, and jams to add tang and act as a mild preservative.

Completely harmless. Move on.

INS 500 — Sodium Bicarbonate

Baking soda. The exact same thing your maa adds to idli batter. Used to make biscuits and cakes rise. Safe since the beginning of cooking.

Nothing to see here.

The ones worth knowing about

INS 621 — MSG (Monosodium Glutamate)

You know this one — it's the white powder in Maggi's tastemaker, in every packet of Uncle Chips, and in most fast food seasoning.

MSG has had a terrible reputation in India for decades — blamed for headaches, thirst, and general "Chinese food bad" mythology. But large-scale research has not found a consistent link between MSG and health problems at normal food quantities. The original studies that created its bad reputation were genuinely flawed.

So MSG isn't the villain it's been made out to be.

But here's the real issue with INS 621: it's a flavour enhancer. It makes food taste dramatically more intense and delicious than it naturally would. Which is why you can't stop eating those chips. Which is why instant noodles taste better than they have any right to. Your palate is being trained to find normal, unenhanced food boring by comparison.

That's the actual problem with MSG — not a headache, but a slowly recalibrated sense of what tastes good.

INS 471 — Emulsifier (Mono and Diglycerides of Fatty Acids)

Found in: almost every packaged bread, biscuit, ice cream, and snack bar in India.

INS 471 is what makes packaged bread impossibly soft for two weeks without going stale. It mixes oil and water together so products have a smooth, uniform texture. It's what gives processed food that distinctive "too perfect" consistency that home-cooked food never has.

Generally considered safe. But here's the catch — INS 471 can be derived from either plant or animal fats, and the label won't tell you which. If you're vegetarian or vegan, this matters, and there's currently no way to know from the packaging alone.

The ones to actively watch out for

INS 211 — Sodium Benzoate

This is a preservative used heavily in soft drinks, packaged fruit juices, sauces, and pickles. By itself, it's not the biggest concern.

The problem starts when INS 211 meets Vitamin C (INS 300) in the same product.

When sodium benzoate and Vitamin C combine — which happens inside the bottle, sitting on a shelf — they can form a compound called benzene. Benzene is classified as a known human carcinogen by international health bodies.

Now pick up a "Vitamin C enriched" fruit drink or a "healthy" juice carton. Check if it contains both INS 211 and INS 300 (or ascorbic acid). You'll find both on the same label more often than you'd expect.

This is worth checking — especially for drinks your children have regularly.

INS 110 — Sunset Yellow

INS 110 is a synthetic yellow-orange dye. It's responsible for the vivid colour in many flavoured drinks, instant soups, orange-flavoured sweets, and snack seasonings. That colour that makes food look more exciting and flavourful than it is? Often INS 110.

Several European countries now require products containing INS 110 to carry a warning: "may have an adverse effect on activity and attention in children." The UK asked manufacturers to voluntarily remove it. Many did.

India has no such requirement. INS 110 remains widely used.

If you have young children and you're buying brightly coloured packaged snacks or drinks, check for INS 110, INS 102, and INS 122. They're the artificial colour trio most linked to hyperactivity concerns in kids.

The one rule that makes all of this easier

You don't need to memorise every INS code. You just need one rule:

The more INS numbers on a label, the more processed the product.

A snack with INS 211, INS 110, INS 621, and INS 471 is not just carrying four additives — it's telling you that it needed four chemical interventions to taste good, look appealing, and stay on a shelf. Real food doesn't need that much help.

An ingredient list with no INS codes at all — like dates, peanuts, oats, dark chocolate, almonds, honey — isn't cleaner by accident. It's cleaner because nothing in it needed to be fixed, preserved, coloured, or enhanced.

That's the simplest version of clean label eating. Fewer numbers. More food.

Monkey Bar snacks have zero INS codes. Because ingredients you can actually name don't need a number.
