Zùsto is a new and unique high-quality sugar substitute, which can replace sugar on a 1/1 basis. Food products that are prepared with Zùsto produce the same sensation in the mouth, the same aromas and the same crunch. Not only that, but the taste experience is comparable to that of sugar.

Zùsto is a new, unique combination of various ingredients that are made from natural raw materials, including polydextrose, plant-based fiber from corn and soluble fiber from chicory, supplemented with sweeteners such as isomalt, erythritol, sucralose or steviol glycosides.

Zùsto has less than 100 kcal per 100 g. That is four times less than sugar. Zùsto also has a low glycemic index (GI) (less than 22; table sugar/sucrose has a GI of 70, glucose/dextrose/fructose a GI of 100) and contains no digestible carbohydrates. The glycemic index indicates how fast carbohydrates are converted into glucose from the intestinal tract and absorbed into the blood.

Anyone who wants to avoid products with added sugars, in particular diabetics and people who want to lose weight, can incorporate Zùsto into their diet.

We work with taste, the taste experience. With “gustus” (Latin) or “gusto” (Esperanto). Also with the English “gusto”, which means something like “individual, refined taste”. We have also been working on the “sweet” taste for many years.

“Zusto” merges the “z” from the Dutch “zoet” [sweet] with the word “gusto”. To promote brand recognition and memorability, we added an accent to the “u”: Zùsto. Short and to the point. 5 letters, 2 syllables. Easy to remember. Commercially strong A name with a history and a future.

The main difference is that Zùsto keeps the taste and the structure of the prepared product the same as if you had used sugar. It’s much lower in calories as well.

For the simple reason that the use of steviol glycosides (stevia is the name of the plant) in sugar substitutes has not been approved for all applications in Europe.

A Zùsto variant with steviol glycosides is available for certain industrial applications, however.

Zùsto can be used in almost all cases where the recipe calls for sugar.

Absolutely. Zùsto replaces sugar at a 1-to-1 ratio, so you don’t need to make any adjustments to your recipes. If your recipe says 100 grams of sugar, just substitute 100 grams of Zùsto. It’s as simple as that!

Yes, you can. Just replace the sugar in the original recipe with an equal amount of Zùsto, or even a little less. Do you want to make a classic white meringue? Use Zùsto and the result will be as tasty, crispy and creamy white as when you use sugar. For optimal results we do recommend baking the meringue at a slightly lower temperature and letting it dry longer.

Yes, it is perfect for that, too. Prepare the crème brûlée according to the classic recipe, sprinkle each dish with a thin layer of Zùsto and caramelize it with a torch or briefly place the dishes under a hot grill.

That is an excellent idea. Using Zùsto instead of sugar actually results in fuller, firmer, more stable whipped cream.

On the contrary, Zùsto enhances both the taste and the smell of the fruit.

You can avoid lumps by gradually stirring the Zùsto into the butter. If you’d rather not take any risks, a better way to do it is to first mix the right amount of Zùsto with another ingredient, such as flour. Then you can add the butter without any problems.

You can also mix the Zùsto with the eggs first. That way the Zùsto is dissolved right from the start.


Zùsto is a source of healthy fiber. It has a low glycemic index and is low in calories, and it is easy to incorporate into your diet if you want to avoid or reduce added sugars.

Zùsto can be incorporated into the diet of people who want to avoid products with added sugars, either because they have diabetes or because they want to lose weight.

No, you don’t have to, but eating less sugar is a good start. All scientists agree: we eat too much sugar, which has resulted in a dramatic increase in diseases of affluence such as obesity, diabetes and cardiovascular disease. Zùsto is ideal if you want to avoid products with added sugars.

Zùsto can be used by anyone, including children. Do make sure that they are consuming enough calories and that their main diet consists of a healthy variety of foods.

No, Zùsto is completely gluten-free and is therefore suitable for people who are on a gluten-free diet.

Fiber, including fiber from corn and chicory, are the main components of Zùsto. They provide the sweet taste and structure, and they are a source of food for good bacteria.


Bernard Proot from bakery DelRey in Antwerp was regularly asked by customers whether he had any products without added sugars. Since this was a niche market for which no satisfactory solution existed yet – existing products with sugar substitutes had too many drawbacks, especially with regard to taste and structure – Bernard Proot started looking for other options. Zùsto’s claims appealed to him, and he started experimenting extensively. He was completely persuaded by the results.

Because there is no need to adjust existing recipes: Zùsto replaces sugar on a 1/1 basis. It also enables him to meet the needs of customers who want to reduce their sugar intake, by offering products that contain little to no added sugar without sacrificing taste and structure.

Yes, Zùsto is now available for consumers. Anyone can work with Zùsto, even people who cook as a hobby, provided they use and store the product correctly, just like any other product.
