Texture Engineering in Protein Products: How Maltodextrin, Creamers and Stabilizers Actually Shape Mouthfeel
When people talk about protein products, they usually talk about protein percentage, flavor names or sweeteners. Texture is mentioned last — if at all. And yet, texture is often the reason a product quietly disappears from someone’s routine.
Texture is not something that “happens”.
It is something that is built.
In protein systems, texture is the sum of how water is structured, how solids hydrate, how fat (or its substitutes) lubricate the mouth, and how stable that perception remains from the first sip to the last — and from the first week to the last month of shelf life.

Protein alone rarely creates a comfortable texture.
High-protein liquids, especially those based on isolates, tend to feel thin, drying and sometimes astringent. This is not a flaw of processing; it is a direct consequence of protein purity. The more protein you concentrate, the less structural “support” remains in the system.
Texture engineering exists to restore that missing structure.

Maltodextrin is usually the first misunderstood tool in this layer.
On paper, it is “just a carbohydrate”. In reality, in protein products it behaves as a structural filler. Low-DE maltodextrins — typically in the DE 5 to 12 range — are used not for sweetness, but for body. At relatively modest inclusion levels, often somewhere between three and ten percent of the total formula, maltodextrin increases the total dissolved solids enough to change how the liquid feels.
The drink becomes less watery, less sharp, more cohesive. Drying sensations are reduced. Flavor transitions feel smoother. The product stops feeling like protein dissolved in water and starts feeling like a beverage.
Push maltodextrin too far, however, and the system becomes heavy, dull and nutritionally unbalanced. Texture improves, but perception suffers. This is why maltodextrin works only when it supports protein — not when it replaces it.

Creamers address a different problem.
Where maltodextrin builds body, creamers build lubrication.
Fat — even in very small amounts — changes how the tongue interprets texture. A fat contribution of one to three percent in the finished powder is often enough to dramatically reduce chalkiness, soften mouthfeel and make aftertaste fade more naturally.
In dairy-based systems, milk-derived creamers integrate easily. Their fat composition and emulsification behavior align naturally with whey and milk proteins. They tend to feel “right” almost immediately, provided oxidation and labeling constraints are respected.
Non-dairy creamers are more complex. They are not just fats, but systems: oil, carrier (often maltodextrin), and emulsifiers locked together during spray drying. Their behavior depends heavily on particle size, surface treatment and how they interact with the protein matrix.
When chosen well, non-dairy creamers can deliver smooth, neutral mouthfeel even in vegan systems. When chosen poorly, they create waxy sensations, delayed flavor release or unstable texture that changes during storage. Two creamers can look identical on a spec sheet and behave completely differently in a protein drink.
This is why creamers are never “drop-in ingredients”. They must be tested inside the full system.

Sensory stabilizers come last — and ideally, they are never noticed.
These are used at very low levels, often below half a percent, not to thicken the product but to control how texture behaves over time. They prevent the drink from feeling thin after a few seconds, reduce separation perception, and help the mouthfeel stay consistent regardless of how aggressively or lazily the consumer mixes the product.
Their role is not to impress.
It is to prevent irritation.
If someone can feel a stabilizer working, the formulation has already gone too far.

What matters is that none of these tools work in isolation.
- Maltodextrin without fat feels flat.
- Fat without body feels greasy.
- Stabilizers without a stable protein matrix feel artificial.
Texture engineering is not about adding ingredients. It is about balancing forces.
Every improvement narrows tolerance somewhere else. Better mouthfeel may reduce solubility. Added fat may suppress aroma. Stabilizers may affect flowability. This is why experienced manufacturers aim for the minimum effective correction, not the maximum possible smoothness.
Daily protein products do not need luxury.
They need effortlessness.

At BF-ESSE, texture is engineered late, not early.
We first make sure the protein system itself behaves correctly. Only then do we introduce maltodextrins, creamers or stabilizers — and always in the smallest ranges that remove discomfort without creating dependency.
This discipline is what allows protein products to survive real-world use, not just lab testing.

Texture is not decoration.
It is structure perceived by the human body.
When texture is right, people don’t talk about it.
They just keep drinking.
And in protein products, that is the only success metric that matters.
