Many products on the market contain large amounts of sugar, which is an important contributor to overweightness and obesity. The purpose of the research was the sensory analysis of four samples of apple nectars and eight samples of blueberry yoghurt with focus on assessment of sweetness. Using sensory analysis, we assessed the intensity of sweetness and sourness of the samples. Additionally, liking was assessed on the 9-point scale. Samples were evaluated by a panel of 30 students enrolled in Biotechnical Faculty in Ljubljana. We checked the nutritional values and found out that the declared sugar content in apple nectar samples ranged between 5.4 and 10.3 g/100 g of the product. The assessed intensity of sweetness did not greatly differ among apple nectar samples. In terms of liking, the sample that was assessed as the sweetest, obtained the highest hedonic score, even though the assessors reported lower ideal sweetness. The declared sugar content in blueberry flavored yogurt ranged from 3.8 up to 14 g/100 g of product. Blueberry yoghurt sample without added sugar, were assigned the lowest sweetness score in sensory analysis. Regarding assessment of liking, the sample with average assessed scores of sensory properties that were similar to average scores of the ideal sensory properties was the most liked. Additional research included the general anchor questionnaire on yoghurt and fruit beverages, which was filled by 246 consumers. We concluded that consumers prefer less sweet products, but still sweet enough, that it doesn't affect liking of the product itself. Fruit beverage consumption among the questioned is low. The vast majority of the questioned can't tell the difference between fruit juice and fruit nectar, which can result in a less healthy choice. Furthermore, we concluded, that consumers often consume yoghurt. When buying yogurt, they look for yoghurt with a low sugar content.
