Abstract

This study aimed to evaluate the effect of adding sweet star fruit (Averrhoa carambola L.) juice on the physicochemical and sensory properties of cow’s milk yoghurt. A Completely Randomized Design was applied with five treatment levels (0%, 2%, 4%, 6%, and 8% juice addition) and four replications. Parameters assessed included fat content, moisture, vitamin C, total acidity, pH, viscosity, and organoleptic attributes (color, aroma, texture, taste, and overall preference). The data were analyzed using ANOVA, Least Significant Difference (LSD) test, and Kruskal-Wallis test at a 95% confidence level. Results indicated that sweet star fruit juice significantly increased vitamin C content and influenced total acidity, taste, and preference (P<0.05), while having no significant effect (P>0.05) on fat content, moisture, pH, viscosity, or texture. The 6% juice addition yielded the most preferred yoghurt based on sensory evaluation. These findings suggest that incorporating sweet star fruit juice can enhance the nutritional and sensory qualities of cow’s milk yoghurt, offering a novel functional dairy product.
