As a result of the optimization, lycopene, ascorbic acid, total phenolic content and DPPH were determined as 28.74 mg/100 mL, 4.34 mg/100 mL, 122.2 mg GAE/L and 54.26%, respectively. When compared to the fresh red watermelon juice samples applied ultrasound with control samples, it was found that lycopene, total phenolic content and DPPH values increase and ascorbic acid content decreased.en10.55507/gopzfd.1138189info:eu-repo/semantics/openAccessBioactive componentsFresh Red Watermelon JuiceResponse Surface MethodologyUltrasoundArticle3921131191124373
