| Abstract | abstract Pervaporation experiments with PERVAP TM 4060 membrane have been performed to study its ability toconcentrate some aroma compounds identified in the brown crab boiling juice from a model diluteaqueous solution. The effect of feed concentration, pervaporation temperature and permeate pressureon the pervaporation performance of the membrane has been analyzed. The results obtained withPERVAP TM 4060 membrane were compared with experiments performed in a previous work with aPOMS/PEI membrane. Membrane material seems to be a key factor in the permeate aroma profile. Thepresence of non-volatile compounds, such as sodium chloride, in brown crab boiling juice slightlyimproves pervaporation performance in the concentration range studied in this work. Batch pervapora-tion experiments prove that the flavor loss percentage during long operation time is high, especially forthe most volatile compounds. Additionally, it has been shown that pervaporation can be significantlyimproved by modifying the permeant circuit by means of two stage condensation step.& 2012 Elsevier B.V. All rights reserved. |
