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.

This study was carried out to investigate the quality characteristics and antioxidant activity of yogurt dressing prepared with different amounts (0, 5, 10, 15, and 20%) of black currant (Ribes nigrum L) extract. All samples were evaluated for chemical composition, pH, viscosity, sugar content, color, organic acid content and antioxidant activity. Our findings revealed that with increasing amounts of black currant extract in yogurt dressing, the moisture, crude protein and crude lipid contents decreased. The pH and viscosity gradually decreased, whereas the sugar increased with increase in black currant extract. Further, the lightness (L) value decreased, while the redness (a) and yellowness (b) values increased with increase in added black currant extract. Among the organic acids, the contents of citric acid, malic acid, succinic acid and acetic acid increased, while that of tartaric acid and lactic acid decreased with increasing levels of added black currant extract. The total polyphenol and total anthocyanin contents were 5.90-245.97 mg/100 g and 0.62-190.09 mg/100 g, respectively. In addition, the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2’-azino-bis(3-thylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activities significantly increased with increase in added black currant extract.
