Clean Label products stopped being a niche a long time ago—consumers now expect short ingredient lists that don’t include E-numbers.
Pregelatinized starches and flours (Clean Label) are functional ingredients that enable the production of foods that continue to meet expectations in terms of product stability, texture, mouthfeel, and labeling.
Functionality Without E-Numbers
Pregelatinized starches and flours (Clean Label) are native products that have been "modified" through physical and mechanical processes.
To stabilize them, the products may undergo heat treatment, pressure, and/or separation processes. This enhances process stability, freeze-thaw stability, and acid stability of Clean Label starches. They are available as stabilized food starches, instant starches, and pregelatinized flours.
Advances in stabilization methods have led to continuous improvements in product stability, so that today, Clean Label products can replace modified starches in many applications.
Instant starches and precooked flours are partially gelatinized through the application of steam, then dried by drum drying, extrusion, or spray drying.
Depending on the drying method used, the starches and flours may require an additional milling step.
Hot pregelatinization gives starches and flours the ability to absorb and retain large amounts of water—even at low processing temperatures.
Both the pregelatinization method and particle size significantly influence water-holding capacity as well as the rate of dispersion and dissolution.
In simple terms, the following properties stand out:
- Smaller particles absorb water more quickly and create smoother surfaces.
- Larger particles or flakes disperse more slowly but create fewer hydrostatic effects and are more easily incorporated without forming lumps.
- They develop viscosity more slowly and reach a lower final viscosity.
- Products obtained through drum drying generate viscosity quickly and reach high levels.
- Spray drying is a gentler process that better preserves the original starch structure. As a result, many of these starches show a slight increase in viscosity when moderately heated. In contrast, products dried via drum or extrusion tend to maintain stable viscosity or even decrease under the same conditions.
Apart from stabilization, the fundamental properties of Clean Label starches remain comparable to those of native starches; you can find a summary here.
Due to their mild "modification," these starches and flours do not need to be declared as modified. Instant starches are most commonly declared as "starch," and pregelatinized flour as "flour" or "pregelatinized flour." As with all other products, if the raw material contains allergens, the allergen source must be clearly indicated.
Versatile Applications of Clean Label Texturizers
In the food industry, these ingredients are used in a wide variety of applications and serve multiple technological functions such as thickening, stabilizing, and gelling.
Thanks to their high water-holding capacity, they help maintain food freshness and significantly contribute to product integrity.
Baking
They increase dough volume and make it easier to handle by enhancing its elasticity. Adding pregelatinized flours allows more water to be incorporated into the dough, which helps extend the bread’s shelf life.
In gluten-free bakery products in particular, there is often a lack of structure during shaping and in the early stages of baking due to the absence of the gluten network—this is where precooked flours can be especially helpful.
Instant starches, such as wheat starch, are often used to adjust the viscosity of doughs in shelf-stable bakery products and pastries. Starches help compensate for fluctuations in flour quality (e.g., low gluten quality).
Plant-Based Dairy Alternatives
Plant-based dairy alternatives lack the milk proteins responsible for forming a light gel and creamy texture. Clean Label tapioca starches not only provide desirable textural effects, but also offer high resistance to demanding processes and retrogradation, enabling them to withstand the harsh production conditions and extended refrigerated storage of yogurt alternatives.
Thanks to organic-quality Clean Label tapioca starches, it is possible to produce yogurt alternatives with not only a clean and appealing label, but also a focus on sustainability.
Soups and Sauces
Depending on the desired consistency, required heat stability, acid resistance, or whether the starch needs to gelatinize in cold conditions, there is a wide variety of products to choose from. For example, UHT-treated sauces like mayonnaise require highly functional thickeners—preferably cold-swelling—with a long, smooth texture.
Instant starches based on tapioca or potato may be suitable ingredients, depending on the preferred botanical source. For dehydrated sauces and soups prepared by the consumer, corn or potato starches provide quick hydration and a creamy mouthfeel.
Wheat starches, with their strong white opacity, are ideal for whitening and can partially replace cream, milk, or other whitening agents.
Coarser pregelatinized wheat flours are ideal for improved mixability and for preventing lump formation. They are less hygroscopic and therefore easier to hydrate.
Fruit Fillings
Fruit fillings must retain their properties even when refrigerated or frozen, and under acidic pH conditions. Pregelatinized tapioca starches give fruit fillings a smooth, glossy surface with high transparency, without the risk of syneresis or delayed thickening.
Starches also play an important role in dessert and pastry creams, where they provide a rich and creamy mouthfeel. In addition, they ensure bake stability and help the creamy mass maintain its shape. This means cakes and baked goods can be filled and decorated creatively.
Depending on whether the creams are prepared cold or hot, baked and/or frozen, there is a range of potato, tapioca, or waxy corn starches to choose from.
Savory Snacks
In directly expanded snacks, pregelatinized potato-based starches achieve the desired expansion and firmness. In contrast, pregelatinized wheat starches are particularly well-suited for baked snacks, resulting in a pronounced crispy texture.
Depending on the type of snack and the production process, blends of hot- and cold-swelling starches are used. For coated nuts, for example, typical formulations include 50–85% native starches and 15–50% cold-swelling starches. The choice of starches depends on the desired texture, the processing method, and the ingredients used.
Meat Alternatives
Meat alternatives are expected to match their animal-based counterparts in every aspect of taste and texture. In the past, this was achieved using numerous additives, often resulting in long ingredient lists filled with E-numbers.
This is where Clean Label starches come in—they help create a meat-like texture while keeping the ingredient list simple and consumer-friendly.
Potato starches, with their high gelatinization capacity, provide a juicy mouthfeel and, when combined with fibers, deliver the product stability needed to withstand demanding processing conditions and freeze-thaw cycles.
