What is Maltodextrin? Why Clean-Label Brands Are Moving Away From It

What Exactly is Maltodextrin?

Maltodextrin is a polysaccharide — a carbohydrate — produced by partial hydrolysis of starch. The starch source is typically corn (maize), wheat, or tapioca, and the hydrolysis is carried out using water and enzymes or acids. The result is a white or off-white powder that is mildly sweet, almost flavorless, and highly water-soluble.

From a nutritional standpoint, maltodextrin is a rapidly digestible carbohydrate. It has a very high glycaemic index (GI) — typically between 85 and 110, higher than table sugar (which sits at around 65). This means it raises blood glucose levels quickly, making it a poor choice for consumers managing blood sugar, following low-GI diets, or seeking genuinely nutritious food.

Despite these characteristics — or perhaps because of its blandness and versatility — maltodextrin has found its way into an enormous range of processed food products, often without consumers realising just how much is present or why it was added.

Why is Maltodextrin Added to Food Powders?

There are three primary reasons maltodextrin ends up in food powders, and all three are related to manufacturing convenience rather than nutritional benefit.

• Carrier agent for spray-drying: This is the most significant reason in the context of dehydrated food ingredients. When liquid extracts are spray-dried into powder form, the resulting fine particles are extremely hygroscopic — they absorb atmospheric moisture and clump together instantly. Maltodextrin encapsulates these particles, prevents clumping, and allows the powder to flow freely. Without it, spray-dried powders simply cannot be processed, packed, or used.
• Bulking agent and cost reducer: Maltodextrin is cheap to produce and has a neutral flavour profile. Adding 30–50% maltodextrin to an expensive vegetable extract significantly reduces the cost per kilogram of the final powder. From a manufacturer's margin perspective, it's attractive — but it dilutes the quality and value of the ingredient for the buyer downstream.
• Flow improvement and anti-caking: Even in non-spray-dried products, maltodextrin is sometimes added as an anti-caking agent to improve the flowability of powders during high-speed production line dosing and filling. However, for naturally dehydrated whole vegetable powders, this is rarely necessary when moisture is properly controlled.

How Much Maltodextrin is in Spray-Dried Powders?

The amount varies depending on the product and manufacturer, but industry-standard spray-dried food powders typically contain between 20% and 60% maltodextrin by total weight. In some cases — particularly for high-value or highly concentrated extracts like turmeric oleoresin or concentrated fruit juices — the maltodextrin content can be even higher.

To illustrate the scale of this: a kilogram of "tomato powder" sourced from a spray-drying facility may contain only 400–600 grams of actual tomato solids. The remaining 400–600 grams is maltodextrin. The same is true of onion powder, garlic powder, spinach powder, and most other vegetable powders produced via spray-drying.

This dilution has a direct impact on colour strength, flavour intensity, aroma, and the nutritional profile of the ingredient — all of which affect the performance of your finished product.

Health and Label Concerns

Maltodextrin raises several concerns that are increasingly important to food manufacturers, retailers, and end consumers:

• High glycaemic index: With a GI of 85–110, maltodextrin spikes blood sugar faster than glucose. For products marketed to diabetic consumers, those following low-GI diets, or products in the health and wellness space, this is a direct contradiction of the product's positioning.
• Nutritional dilution: The vegetable or fruit content — the actual source of vitamins, minerals, antioxidants, and phytonutrients — is reduced proportionally. You are paying for active ingredient but receiving a mixture that is largely inert filler.
• Allergen considerations: Maltodextrin derived from wheat contains traces of gluten. While regulatory thresholds in many markets technically classify wheat-derived maltodextrin as gluten-free (as processing removes most protein), this remains a grey area for consumers with wheat sensitivity or coeliac disease.
• Consumer and retailer scrutiny: Sophisticated consumers — and the retailers catering to them — are increasingly reading ingredient lists. The presence of maltodextrin in a product labelled "natural" or "clean" undermines brand credibility and can attract negative attention on social media and in retail buyer reviews.

What Maltodextrin-Free Looks Like on a Label

The difference is visible immediately when you compare ingredient declarations side by side. A naturally dehydrated onion powder from Atlas AgroFood has a single-line ingredient declaration:

This is not a cosmetic difference. It is a fundamental quality difference that affects your product's label, its nutritional profile, and your brand's credibility with increasingly informed consumers and retail buyers.

How Atlas AgroFood Avoids Maltodextrin

Atlas AgroFood uses hot-air dehydration exclusively — not spray-drying. We start with whole, fresh produce sourced directly from farms in India. The produce is cleaned, prepared, and passed through temperature-controlled dehydration equipment that removes moisture without the need for any carrier agent.

Because we dehydrate the whole vegetable or fruit rather than a liquid extract, the dried product retains its physical structure, fibre content, and natural dry matter. There is no technical need for maltodextrin, and we do not use it. Every product we supply — from onion powder to moringa powder — has a single-ingredient declaration. You can read more about our commitment to additive-free processing on our Clean Label page.

How to Verify a Supplier is Maltodextrin-Free

When evaluating dehydrated ingredient suppliers, here are the specific checks you should carry out before placing a bulk order:

• Request the full ingredient declaration: The declaration should list only the vegetable or fruit, with no additives. If maltodextrin, anti-caking agents, or carrier agents appear, ask for an explanation.
• Ask for a Certificate of Analysis (COA): A COA should specify the product's composition. If it does not clearly state "100% [ingredient]" or equivalent, push for clarification.
• Ask about the processing method: Ask directly: "Do you use spray-drying?" and "Is any carrier agent added during processing?" A transparent supplier will answer clearly.
• Request a sample and check solubility: Spray-dried powders with maltodextrin dissolve very quickly in water and leave little residue. Naturally dehydrated powders may take slightly longer to disperse and often leave some fine fibre residue — this is normal and expected.
• Check the colour and aroma: Pure naturally dehydrated powders tend to have more intense, authentic colour and aroma than their spray-dried equivalents, because they are not diluted with maltodextrin.
