Abstract

The objective of this research was to investigate the optimal condition of lipid extraction from Khai-Nam (Wolffia sp.) by ultrasound-assisted extraction (UAE) using response surface methodology (RSM) with Box-Behnken design (BBD). The factors in this work including solid to solvent ratio (0.1:10-1:10 g/mL), extraction time (10-30 min) and sonication power (78-130 Watt). The experimental results showed that these three factors affected yield of lipid extraction. The optimum conditions for lipid extraction were solid to solvent ratio of 0.1:10 g/mL, extraction time of 30 min and sonication power of 130 Watt, which resulted in lipid yield of 9.78%. After the experiments performed under these conditions, the maximum lipid yield was found 9.54 ± 0.31%, which is similar to the prediction value. Therefore, it can be concluded that the regression model obtained from the experimental data could be applied for accurate prediction of the lipid yield obtained by UAE.
