Abstract

Objective: Extraction of Curcuma mangga (C. mangga) using supercritical carbon dioxide (SC-CO₂) was investigated to provide information about the optimum extraction condition.

Methods: A Taguchi method with L₉ orthogonal array design was used to determine the optimum extraction conditions. Effects of extraction pressure, temperature, CO₂flow rate and dynamic extraction time on C. mangga oil yield were investigated at levels ranging between 150-350 bar, 40-60 °C, 10-20 g/min and 120-240 min, respectively.

Results: The highest C. mangga oil yield (5.223%) from SC-CO₂extraction was obtained at a pressure of 350 bar, temperature of 60 °C, CO₂flow rate of 20 g/min and dynamic extraction time of 240 min. The experimental C. mangga oil yield at optimum condition was in a good agreement with the values predicted by computational process using Taguchi method. Based on S/N ratio calculation, the most influencing parameters in maximizing C. mangga oil yield is extraction temperature, followed by extraction pressure, dynamic extraction time and CO₂flow rate.

Conclusion: In this study, Taguchi method was successfully applied to optimize SC-CO₂ extraction of C. mangga. Taguchi method was able to simplify the experimental procedure of SC-CO₂extraction.
