In this study, the effect of different extraction methods on the quality properties of hibiscus extracts was investigated. Therefore, thermal extraction (40 and 75 ºC) and thermosonication (0.031 W/mL, 40 and 75 ºC) applications were performed. In the samples taken at 1st, 5th, 15th, 30th, 60th and 120th minutes during the extraction, an increase in °Brix and anthocyanin content was determined depending on the temperature and time, while pH did not show a significant difference. The samples were then extracted up to 1.1 °Brix. In these samples, anthocyanin content was determined between 149.7-156.2 mg/L, while delphinidin-3-sambubioside and cyanidin-3-sambubioside were determined between 112.1-120.5 and 52.35-55.26 mg/L, respectively. Sucrose was determined as the highest amount of sugar while malic acid was found between 811.2-932.4 mg/L. When the effects of extractions on the quality characteristics were evaluated, it was determined that there was no statistically significant difference between the applications except turbidity values.
