Modelling and Optimization of Processing Factors of Pumpkin Seeds Oil Extraction under Uniaxial Loading

In the present study, a Box–Behnken design of response surface methodology (RSM) was employed to optimize processing factors (force: 100, 150, and 200 kN; speed: 3, 5, 7 mm/min; temperature: 40, 60, 80 °C) for extracting pumpkin seeds oil under uniaxial compression. The generated 15 experiments including twelve combinations three replicates at center point. responses: yield (%), expression efficiency energy (J) were calculated, regression models determined statistically analyzed validated. optimum combination: kN, 4 mm/min °C predicted 20.48%, 60.90%, 848.04 J. relaxation time 12 min increased 64.53%. lower point force be 57.32 kN estimating maximum output. tangent curve generalized Maxwell adequately (R2 = 0.996) described compression processes extraction. Peroxide value with temperatures. study provides detailed information useful different bulk oilseeds loading optimizing mechanical pressing in large-scale production.
