Aroma compounds are widely used as additives in many §products (food, pharmacy and cosmetics). Most §industries applied extraction and distillation to §recover aroma compounds from natural sources; §however, both suffer from disadvantages (product §contamination and energy consumption). Pervaporation §(PV), a membrane separation process, is considered §as a promising technique to overcome above §challenges. This book contains both experimental and §parametric studies dealing with the application of §PV for aroma compound recovery from aqueous §solutions using poly (ether-block-amide) (PEBA) §membranes. The effect of process conditions on PV §performance (permeation flux and selectivity) were §investigated. The solubility and diffusivity of the §aroma compounds in PEBA membrane were evaluated. A §modified PV process was studied parametrically. In §conclusion, PEBA membrane was found selective for §aroma-water separation, the molecular interactions §between permeant-permeant and permeant-membrane had §significant role affecting the mass transfer §behavior of permeant across the membrane, and the §modified PV process could improve the aroma compound §recovery.
