In this study, we characterized the chemical properties of golden berries, which contain various functional substances and bioactive components, to develop a yogurt dressing using golden berry juice. The total polyphenol content of golden berry was 35.29 mg GAE/g, the total flavonoid content was 28.93 mg QE/g, and the DPPH radical scavenging activity was 94.81%. The chromaticity of yogurt dressing with golden berry juice decreased in L value and increased in a and b values with growing amounts of golden berry juice (p<0.001); viscosity decreased significantly with increasing amounts of golden berry juice (p<0.001). Electronic tongue analysis showed that sourness, umami taste, and saltiness increased upon increasing the quantity of golden berry juice, while sweetness and bitterness increased with less golden berry juice. PCA analysis determined that PC1 and PC2 accounted for 63.45% and 35.29% of the variance, respectively. Furthermore, the addition of golden berry juice impacted the analysis of taste patterns. Sensory evaluation showed that color, flavor, sweetness, sourness, bitterness, and overall acceptability were highest in the 30% golden berry juice group. As a result, it was confirmed that adding golden berry juice is suitable for developing yogurt dressings that can improve health functions and palatability.
