Hollow fibre modules for orange juice aroma recovery using pervaporation

Pervaporative recovery of volatile aroma compounds from fruit juices

“…Although some studies have already been conducted with real solutions [53,130,132,140,141,152,158,168,171,172,175,188], most authors have chosen some aroma components and worked with a model feed solution, usually binary. The reasons for such trend lie in the intrinsic complexity of fruit juice aroma, comprising hundreds of different organic compounds, some of which at very low concentrations, as well as in the complexity of the mass-transfer mechanism itself when multicomponent mixtures are used.…”

“…As shown in Fig. 4, polydimethylsiloxane (PDMS) is by far the most used material in the available literature studies on aroma recovery by pervaporation [86,103,[125][126][127][128][129][130][131][132][133][134][135][137][138][139][140][141][142][143][144][145][146][149][150][151][152][153][154][155][158][159][160]162,163,167,168,[171][172][173][174][175][176][177][180][181][182][187][188]...…”

Study and optimization of aroma recovery from beer by pervaporation

“…Besides the high selectivity of membranes, the pervaporation process can be carried out at low temperatures, which is relevant for treating thermo-sensitive beer compounds [3][4][5][6]. On the other hand, pervaporation requires low energy consumption and no chemical additives; it accomplishes a physical separation, which is preferable compared to other kind of separations [5,6,10,12].…”

Recovery of strawberry aroma compounds by pervaporation

“…In addition, Shepherd, Habert, and Borges (2002) studied the use of poly (dimethyl siloxane) (PDMS) hollow fibers in orange juice aroma recovery. Peng and Liu (2003), evaluated separation factor of six constituent aroma compounds, representing some typical flavoring ingredients from blueberry juice with a PDMS membrane.…”
