title = "Central composite rotatable design for investigation of microwave-assisted extraction of ginger (Zingiber officinale)",
abstract = "Microwave-assisted extraction technique was employed to extract essential oil from ginger. The optimal condition for microwave assisted extraction of ginger were determined by resposnse surface methodology. A central composite rotatable design was applied to evaluate the effects of three independent variables. The variables is were microwave power 400 - 800W as X1, feed solvent ratio of 0.33 -0.467 as X2 and feed size 1?cm, 0.25?cm and less than 0.2?cm as X3. The correlation analysis of mathematical modelling indicated that quadratic polynomial could be employed to optimize microwave assisted extraction of ginger. The optimal conditions to obtain highest yield of essential oil were: microwave power 597,163?W: feed solvent ratio and size of feed less than 0.2?cm.",
