One of the negative trends in current nutrition is an increased consumption of refined foods with a low content of useful nutrients and antioxidants and an abundance of oxidation accelerators. Fruit paste and jelly have a relatively low energy value, compared to other confectionery products. Along with this fact, they also have gel- ling agents and fruit raw materials in their composition, which can classify them as diet food. This paper presents a comprehensive approach to developing a technology for producing fruit jelly with an improved carbohydrate profile. For that, we used viburnum and orange puree, a valuable natural plant material, as a source of carbohydrates, and fructose, as a sugar substitute. The qualimetric model created from the tasting data was used to select the optimal proportions of the main ingredients, viburnum and orange puree, as 25:75 and 75:25. The comparative assessment of antioxidant capacity (AOC) showed that the sample with the 75:25 ratio of viburnum to orange puree had an AOC of 22.33 μmol TEq/g. It was twice as high as AOC of the 25:75 ratio sample. With a glycaemic index of 29.2, this fruit jelly can be recommended as a diet food with preventative properties.
