Like sucrose, sugar substitutes belong to the group of carbohydrates. From a legal point of view, they are sweeteners, classified as sugar alcohols (polyols) because of their chemical structure. One of their main characteristics is their sweet taste. Although they are somewhat less sweet than sucrose – between 40 and 80 % depending on the product – the taste profiles of some sugar substitutes are very similar to that of table sugar.
Their sweet taste in combination with a low energy content and low glycaemic index make polyols as a product group equally attractive to both consumers and industry.
