This study investigates the underlying extraction kinetics and thermodynamic principles driving the process, building on earlier research that enhanced thermosonication (TS) settings to boost the bioactive components of Sohshang () fruit juice. Responses were assessed over a temperature range of 30 °C to 50 °C after the ideal thermosonicated sohshang fruit juice (TSSJ) processing parameters (50% amplitude, 40 °C, and 60 minutes) were determined using the integrated ANN-GA model. The study uses kinetic modeling to determine the best mathematical fit by analyzing the release patterns of functional components like ascorbic acid (AA), total phenolic content (TPC), total flavonoid content (TFC), and antioxidant activity (AOA).
