What is Maltodextrin?

REPEAT GUD·The Label Files·No. 01·6 min read
Ingredient Investigation

You've probably never heard of maltodextrin. But chances are, you've eaten it today.

It's the cheapest trick in packaged food.

Maltodextrin is starch that's been chopped into tiny pieces in a factory. Your body absorbs it instantly , so it can spike your blood sugar faster than actual sugar. And because of a labelling technicality, it doesn't get counted as sugar at all. That's how a pack says sugar-free and still spikes you.

Not because you weren't paying attention. Because it was designed not to be noticed.

Here's how it gets in.

Making a sauce thick is genuinely hard. Ask anyone who has tried to get their grandmother's imli chutney to that perfect, spoon-coating consistency at home. Twenty minutes on a slow flame, and it's still either watery or a brick.

A FACTORY DOES NOT HAVE TWENTY MINUTES.

So it reaches for a powder instead. No taste. No smell. No colour. Costs almost nothing and turns anything thick and creamy in about four seconds flat.

That powder is maltodextrin.

Once you know the name, you'll start seeing it everywhere. Ketchup. Protein bars. Low-fat yoghurt. Instant soup. Masala mixes. Some infant formula.

It annoys us. Not because it's poison it isn't. But because it is the easiest way in the world to make cheap food feel expensive, and almost nobody eating it knows it's there.

Full disclosure before we go any further: we make sauces for a living. We have never used maltodextrin in any of them which is exactly how we know how much easier our lives would be if we did.

I.So what actually is it?

Forget the chemistry. Here's the whole thing.

Starch in a potato, in rice is a long, coiled rope. When you eat it, your body has to walk along that rope snipping it into pieces before it can use any of it. That takes time. Which is good. Slow release, steady energy, no 4pm collapse.

Maltodextrin is that same rope. Already snipped. Before it ever reaches your mouth.

Your body has nothing left to do. It just absorbs it.

The industry term for this is "partial hydrolysis." The honest term is pre-digested.

And here's where it gets useful for them: because the leftover chains are technically long-ish, maltodextrin gets classified as a complex carbohydrate. Complex! Sounds wholesome. Sounds like brown rice and good decisions.

YOUR BODY CANNOT READ.

II.Hang on. Faster than sugar?

Yes. Sorry.

Quick definition, and this is the only slightly technical bit in the whole piece. Glycemic Index is a scoreboard for how fast a food pushes your blood sugar up. Pure glucose is the benchmark at 100. Higher number, sharper spike, harder crash.

Table sugar ~65
Pure glucose 100
Maltodextrin 85–136

Sources disagree on the exact figure: Healthline says 110, MedicineNet says 106–136, MDVIP says 95–136. They disagree on the number. Nobody disagrees on the direction.

So a powder sold as a neutral, boring, invisible thickener can hit your bloodstream harder than a spoonful of cheeni. Welcome to the Complex Carbohydrate™ loophole. Perfectly legal. Perfectly useless to you.

Now the part that catches everyone. On a nutrition panel, maltodextrin is counted under total carbohydrate , not under sugars. Its chains are just long enough to dodge the definition.

Which is how a product can print 0g sugar on the front, in a nice rounded font, next to a small green leaf, and still spike you like glucose.

Nobody is lying. The rules simply allow it.

"Sugar-free" does not mean "spike-free."

Print it on your fridge

III.Then why is it in everything?

Because it solves boring, expensive problems. Cheaply. That's genuinely the whole answer.

  • It thickens instantly. No slow flame, no time, no skill required.
  • It adds weight for pennies. Pull the fat or sugar out of a recipe and it goes thin and hollow. This puts the body back.
  • It stops powders clumping. Masala mixes, drink powders, protein tubs.
  • It survives a warehouse. Months on a shelf, no change in colour or taste.
  • It carries flavours and colours. Spreads the strong stuff around evenly.

There is exactly one honest use for it: sports nutrition. A runner at kilometre 30 genuinely wants a fast carb hit, and maltodextrin delivers one. That's real. That's fine.

YOU, EATING A "HEALTHY" BAR AT YOUR DESK AT 4PM, ARE NOT THAT RUNNER.

IV.Okay, but is it actually bad for you?

We're going to be careful here, because scaremongering is just dishonesty with better marketing.

Maltodextrin is legally permitted in food, in India and everywhere else. Regulators consider it safe at normal levels. It is not going to hurt you.

But "legally safe" and "good for you" are two completely different sentences. Sand is also legally safe. We don't put it in ketchup.

What it actually does, honestly:

  • Spikes, then drops you. That's the afternoon slump, and the snack you want one hour after eating.
  • Delivers calories with nothing attached. Same 4 calories per gram as sugar. Zero fibre, zero vitamins, zero minerals.
  • May bother your gut bacteria. A 2012 study in PLOS ONE found it helped certain unhelpful bacteria cling to the gut lining, and later NIH-listed research looked at its effect on the gut's protective mucus layer. Honest caveat: most of that work is petri dishes and mice, not people. Worth flagging. Not worth panicking about.

IT ISN'T A VILLAIN. IT'S A FREELOADER.

Shows up at the party, contributes nothing, takes up space, leaves before the dishes.

V.How to catch it in ten seconds

FSSAI already requires every packaged food in India to print its full ingredient list. The information is on the pack. Most of us have simply never turned it around.

  1. TURN THE PACK OVER.

    The front is advertising. The back is regulated. Only one of those has rules.
  2. SKIP THE ADJECTIVES.

    Natural, light, diet, wholesome, clean. These words mean almost nothing. Go straight to the ingredient list.
  3. CHECK ITS POSITION IN THE LIST.

    Ingredients are listed by weight, heaviest first. Top three or four means there's a lot of it and you're paying for filler at food prices.
  4. LOOK FOR THE COUSINS.

    Cornstarch, modified starch, liquid glucose, glucose syrup, dextrose, corn syrup solids. Same trick, different costume.

This piece is general education, not medical advice. If you're managing diabetes or insulin resistance, talk to your doctor or a registered dietitian about your own diet — ICMR's dietary guidelines are a decent starting point too.

VI.Fine. And what about you lot?

Entirely fair question. You've just read a sauce company explaining what's wrong with sauce.

So here's our label. Imli & Date Sauce, every single ingredient in it:

Ingredients — all eight of them
  1. Dates
  2. Imli (Tamarind)
  3. Water
  4. Organic Jaggery Powder
  5. Himalayan Pink Salt
  6. Ginger Paste
  7. Natural Spices & Condiments
  8. Fruit Pectin

Number eight is the entire point. Fruit pectin is the stuff that makes jam set. It comes from fruit. It is what was quietly holding your grandmother's chutney together the whole time, and she never had to buy it. Also in the ketchup: no cornstarch either. That one's on the pack.

That's our thickener. Nothing in that bottle is doing a job that dates and tamarind can't do on their own.

And here's the other half of the label , the half most brands would rather not print. The list of things we decided to leave out:

Not in the bottle
  • Maltodextrin
  • Cornstarch / corn flour
  • Refined sugar
  • Sodium benzoate
  • MSG
  • GMOs
  • Palm or soy oil
  • Artificial preservatives

Every batch goes to an NABL-certified lab before it goes anywhere near you.

It costs us more. It takes longer. And our bottle doesn't have that suspicious mirror-shine the big ones do.

WE'RE COMPLETELY FINE WITH THAT.

VII.The verdict

Next time you're in a shop, turn the pack around. Find the maltodextrin. Then decide whether you actually want to pay for it.

Because if it's sitting in the top three ingredients, you're not really buying food. You're buying filler with a good font.

GOOD FOOD SHOULDN'T NEED A MAGIC POWDER. IT SHOULD JUST BE GOOD FOOD.

FAQQuick answers

What is maltodextrin?
A white, tasteless powder made by chopping starch from corn, rice, wheat or potato into much smaller pieces in a factory. It's added to food as a cheap thickener, filler and bulking agent.
Is maltodextrin bad for you?
It's legally permitted and it isn't poisonous. But it has no fibre, vitamins or minerals, and your body absorbs it instantly, so it can raise blood sugar faster than table sugar. Treat it as a filler to limit, not an ingredient to look for.
What's the GI of maltodextrin?
Published figures run from about 85 to 136 depending on how it's made. Table sugar sits near 65 and pure glucose is 100 — so it can spike you faster than sugar itself.
What is maltodextrin used for in food?
Thickening sauces, adding cheap bulk to low-fat and sugar-free products, stopping powders clumping, extending shelf life, carrying flavours and colours, and as a fast carb in sports drinks.
Why does a "sugar-free" product still spike me?
Because maltodextrin is counted under total carbohydrate on the panel, not under sugars — its molecular chains are just long enough to dodge the definition. So a pack can honestly print 0g sugar while behaving like glucose in your body.
Do REPEAT GUD sauces contain maltodextrin?
No. No maltodextrin and no cornstarch. Thickness comes from fruit pectin, dates and slow cooking, sweetness from organic jaggery. Every batch is NABL lab-tested. You can read the full story here.

Made the slow way, since we couldn't find anyone else doing it

Thick because of dates, tamarind and time. Not because of a lab powder.

Onion-and-garlic-free house? There's a Jain Ketchup. Or just see everything we make.
