Optimal extraction conditions were established by conducting extractions at varying temperatures and times using the optimal ethanol ratio. The optimal extraction conditions and concentrations are as follows: galangin (190 °C, 20 min); chrysin (190 °C, 10 min); total phenolic content (210 °C, 10 min); total flavonoid content (210 °C, 10 min). The highest antioxidant activities were observed at 210 °C for 15 min, and at 200 °C for 20 min. Compared to conventional methods, pilot-scale SSE minimizes ethanol usage, offering an eco-friendly and cost-effective alternative. Additionally, SSE enhances extraction efficiency while reducing processing time. These advantages contribute to industrial applications by promoting sustainable extraction practices and improving yield. Overall, SSE presents a promising method for propolis extraction, balancing efficiency and environmental benefits.SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s10068-025-02071-y.PMID:41766981 | PMC:PMC12946575 | DOI:10.1007/s10068-025-02071-y
