Response: Yield (%) Actual factor: C: pH = 1,49 Response: Yield (%) Actual factor: B: Power= 1335 Response: Yield (%) Actual factor: A: Time = 3,67 (C) (A) (B) Yield (%) B: Power (W) A: Time (min) Yield (%) Yield (%) C: pH A: Time (min) C: pH B: Power (W) Response surface plots for pectin • Extraction time is a key variable influencing yield • Plots reveal additional interactions – lower pH can improve yield if extraction time is short • Significance of the interaction between time and power
