Comparison of the Sensory Properties of Geographically Indicated Konya Reyhan Sherbet Developed with Alternative Sweeteners
This study aims to examine consumer preferences when natural sweeteners (stevia, mulberry molasses, carob molasses, and pine molasses) are used instead of white sugar in the traditional recipe of Konya Reyhan Sherbet, which has been registered with a geographical indication by TÜRKPATENT. The study seeks both to contribute to the preservation of local products and to highlight their functional properties. In this research, the sensory analysis method, one of the experimental techniques, was employed, and 69 consumers evaluated the products based on color, aroma, taste, flavor, and overall acceptability through a detailed hedonic test. The data obtained from participants were statistically analyzed, and to increase reliability, Friedman and Wilcoxon tests were applied. The findings revealed that the control group, R51, received the highest scores across all criteria, showing that the traditional formulation is still strongly preferred. However, among the alternative products, the sherbet coded R36 with stevia stood out particularly in terms of taste, flavor, and overall acceptability, ranking second. The sherbets containing pine molasses (R85) and mulberry molasses (R92) received moderate appreciation, remaining behind R36. The sample coded R70 with carob molasses obtained the lowest scores in all criteria and was inadequate in meeting consumer expectations. As a result, the stevia-based Reyhan sherbet emerged as a strong alternative to the traditional product, while R92 with mulberry molasses and R85 with pine molasses could also serve as potential alternatives if further developed. Overall, the study emphasizes the role of natural sweeteners in developing local and functional products and provides detailed, guiding findings regarding the industrial applicability of innovative alternatives such as stevia in traditional foods.
