Zùsto is a new and unique high-quality sugar substitute. Use it to replace sugar on a 1:1 basis. Food products that are prepared with Zùsto deliver 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. However, Zùsto has less than 100 kcal per 100 g. That is one quarter the amount in sugar.

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

Anyone who wants to avoid products with added sugars, in particular people with diabetes or who are aiming to lose weight, can incorporate Zùsto into their diet. This is because Zùsto has a low glycaemic 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 glycaemic index indicates how fast carbohydrates are converted into glucose from the intestinal tract and absorbed into the blood.

We work with taste and the taste experience: ‘gustus’ in Latin and ’gusto’ in Esperanto. We have also been working on the ‘sweet’ taste for many years.

‘Zùsto’ combines 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. Five letters. Two syllables. Easy to remember. Commercially powerful. A name with a history and a future.

The main difference is that although Zùsto delivers the same taste and structure in the prepared product as sugar would, it’s much lower in calories.

Use it in almost any recipe that calls for sugar.

Absolutely. Zùsto replaces sugar at a 1:1 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, it’s perfect for that, too. Prepare the crème brûlée according to the classic recipe, sprinkle each dish with a thin layer of Zùsto and either caramelize it with a torch or place the dishes under a hot grill.

It’s 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.

Avoid lumps by gradually stirring the Zùsto into the butter. If you’d rather not take any risks, first mix the right amount of Zùsto with another ingredient, such as flour, then add the butter.

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


Zùsto is a source of healthy fibre. It has a low glycaemic index, it’s low in calories, and it’s 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 (from 1 year). Do make sure that they’re consuming enough calories and that their main diet consists of a healthy variety of foods.

No, Zùsto is completely gluten-free. It’s suitable for people who are on a gluten-free diet.

Fibres, including fibres from corn and chicory, are the main components of Zùsto. They provide the sweet taste and structure. They are also a source of nutrition for the good bacteria in your digestive tract.


Bernard Proot, from the DelRey bakery 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 at the time – the only sugar substitutes available 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 fully convinced 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 or no added sugar, without sacrificing taste and structure.

Anyone can work with Zùsto, even people who cook as a hobby. Just remember to use and store Zùsto correctly, as you would any other product.
