Abstract

Extraction of Allium sativum L. using Solvent-Free Microwave Extraction (SFME) without the addition of solvents in the process has been carried out. SFME is an alternative technique and method to produce essential oil and it has several advantages in terms of product quality. In this study, the essential oil was extracted from Allium sativum used extraction time from 10 to 90 min and microwave power in the range of 300-600 W. The result showed that SFME could produce the highest yield of 0.2636 g oil/100 g fresh garlic at 450 W and 90 min. In addition, the kinetic study of SFME model appears to be the best fit to explain with second-order than first-order model. It was proved by a good correlation between the experimental data and model achieved (R2>0.99) and (RMSE=0.0021). Based on the results obtained, second-order kinetic models could actually describe the kinetics model of extraction process from Allium sativum L. using SFME.
