Optimization of Oil Extraction and Characterization from Tamarindus Indica Linn Seed Oil

摘要

The oil yield, fatty acid composition and the physicochemical and quality characteristics of Tamarindus indica Linn seed oils obtained by solvent extraction were determined. Effect of various solvent and solvent combinations on the extraction of T. indica seed oil showed that ethanol as an alternative solvent to have better yield with 8%. Optimized process conditions were solid to ethanol ratio of 1:6w/v, under reflux for 6h and agitation speed 100rpm. Extracted oil analyzed by Gas Chromatography-Mass spectroscopy. T. indica oil was tested for its physical and chemical properties including percentage of fatty acid, kinematic viscosity, saponification value, unsaponifiable matter. The stability of T. indica oil during storage at room temperature and during heat treatment was studied. Result of the present research indicates that ethanol can be a better alternative to other solvents. Also indicate that the T. indica seed oil can be used as a potential alternative to nutritional food.
