Zùsto is a patented and unique high quality sugar substitute, that can replace sugar 1:1. Dishes prepared with Zùsto have the same mouthfeel, aromas and crunch. On top of that, the taste experience is comparable to that of sugar.

Zùsto contains less than 100 kcal per 100 g. That’s four times less than sugar. Zùsto has a low glycemic index (GI) and contains no digestible carbohydrates. The glycemic index indicates how fast carbohydrates are converted into glucose and absorbed in the bloodstream.

Everyone who wants to avoid products with added sugars, especially diabetics and people trying to lose weight, can incorporate Zùsto in their diet.

Given that taste experience is essential to our product, we took note from Latin (gustus) and Esperanto (gusto), and “gusto” is associated with enthusiasm and satisfaction – something you’ll definitely experience when using it!

Because sweet is our trademark, we replaced the “g” with a “z” (from the Dutch word for sweet, ‘zoet’), and subsequently, in the spur of the moment, added an accent to the “u”. Short and to the point. 5 letters, 2 syllables. Easy to remember. A name with a history and a future.

Most other sugar substitutes are based on one or two sweeteners. Outside of the sweetness, they provide no health contribution whatsoever and you usually can’t replace sugar at a 1:1 ratio. You have to adjust your recipe and many results aren’t satisfactory in the least. Zùsto contains many healthy and prebiotic fibers, something most people have a deficiency of, and can replace sugar 1:1 while maintaining the same taste!

Zùsto is a unique and healthy combination of prebiotic and plant-based fibers (among which polydextrose, fibers from chicory and corn) and sweeteners (erythritol, isomalt and sucralose).

Zùsto can almost always be used where the recipe requires sugar to be used.

Absolutely. Zùsto replaces sugar at a 1:1 ratio, so there is no need to adjust your recipes. If your recipe requires 100 grams of sugar, just replace it with 100 grams of Zùsto. Piece of cake!

It’s an excellent idea. Using Zùsto instead of sugar actually results in a fuller, firmer and more stable whipped cream.

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

Zùsto is a high-fiber product and therefore doesn’t mix too well with melted butter, which results in lumps. We advise you to mix Zùsto with another dry ingredient (such as flour, cornstarch, cocoa powder,…) or eggs. Afterwards you can add the other ingredients such as butter. Want to mix Zùsto with butter right away? Make sure the butter is at room temperature: take it out of the fridge a few hours in advance, mingle it with a food processor while slowly – spoon-wise – adding Zùsto to avoid the formation of lumps.


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

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

No – that’s not necessary, although eating less sugar is a good start. 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 (aged 1 and up). Ensure that they consume sufficient calories and that their main diet consists of a healthy variety of nutrients.

No, Zùsto is completely gluten-free and therefore suited for people adhering to a gluten-free diet.

Zùsto combines different dietary fibers as polydextrose and fibers from chicory and corn. The different fibers each have a different prebiotic effect and are quite easy to digest by our body. These fibers also provide structure in the dishes they’re used in.

Like other sugar substitutes, Zùsto also contains the natural sweetener erythritol. Zusto, due its unique composition however, contains about 4 to 5 times less erythritol, compared to other sugar substitutes!

Zùsto consists of a meticulously selected blend of healthy dietary fibers. The mix is formulated to technically function like sugar, and to enhance and combine the health benefits of fibers. The main components – almost 70% –  of Zùsto are therefore fibers and not sweeteners. As a result, erythritol is only used in a very limited amount to add additional sweetening power to the blend. Consequently, Zùsto contains much less erythritol, on average about 4 to 5 times less compared to other sugar substitutes.

The selection, combination and proportions of the ingredients used, make Zùsto the tastiest, healthiest and most versatile sugar substitute!

Bernard Proot, of the DelRey bakery in Antwerp, was repeatedly asked by clients whether he had any products without added sugars. Because it was a niche market for which no satisfactory solution existed – available products with sugar substitutes had too many drawbacks, especially regarding taste and structure – Bernard Proot explored other options. Zùsto’s claims appealed to him, and he started experimenting extensively. He was completely convinced by the results.

Because existing recipes do not need to be adjusted: Zùsto replaced sugar on a 1:1 basis. It also enables him to meet customers’ needs who want to reduce their sugar intake, by offering products that contain little or no added sugar, without compromising on taste and structure.

Yes, Zùsto is now available to consumers as well. Anyone can work with Zùsto, even amateur chefs, as long as they use and store the product correctly, as they would do with any other product.
