In the present work, optimization of quality parameters was performed for maximum recovery of turmeric oil from the dried rhizome of turmeric (Curcuma longa L.) using microwave assisted extracted technology.  Petroleum ether and Hexane solvents were used for extraction of essential oil at two different input parameters of microwave i.e.,  microwave power (200, 250, 300, 350 and 400 watt) and extraction time (10, 15, 20, 25 and 30 min). Resulted response were estimated by the ANOVA using central composite rotable design (CCRD) of response surface methodology (RSM) and the polynomial equation of the second order response surface were modelled using multiple regression analysis. The quality of extracted oil was evaluated based on quality parameters. Maximum yield of 4.97 % of oil was recovered with the chemical properties value of acid, iodine and saponification were 4.5%, 39.37% and 14.86 % respectively using Hexane solvent at microwave power of 300-watt and 20 minutes of extraction time. Determination coefficients (R2) were equal to 90% or higher for individual responses stated that the developed models were well fitted to the experimental results.

Keywords    Turmeric oil, Microwave power, Extraction time,  Acid value, Iodine value, Saponification value.
