Dairy aroma compounds recovery by pervaporation

Pervaporative recovery of volatile aroma compounds from fruit juices

“…Since aroma concentrations in the feed solutions are low, membrane plasticization does not usually play an important role and, accordingly, the permeate flux of aroma components is generally a linear function of their concentration [124,129,137,143,146,148,152,153,[160][161][162]166,[179][180][181][182][183][184]186,187], in accordance with Eq. (9).…”

“…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]...…”

Concentration of dairy flavour compounds using pervaporation

“…In most cases, the feed solutions studied were simple model solutions containing up to only three components other than water, and the results varied widely depending on the membranes used and the compounds tested. For example, Baudot and Marin (1996) used pervaporation to concentrate methylthiobutanoate by a factor of up to 1205 and diacetyl by a factor of 15-20. Rajagopalan, Cheryan, and Matsuura (1994) also studied pervaporation of diacetyl from an aqueous solution, and achieved enrichment factors of around 35.…”

Efficient recovery of high‐purity aniline from aqueous solutions using pervaporation‐fractional condensation system

“…1,2 It is a continuous process with minimal energy consumption, and no need to regenerate the membrane and add an additional entrainer and thus no secondary contamination. 3,4 Nowadays, it is widely applied for the removal and recovery of trace amounts of organic compounds from aqueous streams such as separation of aromas and biofuels from fermentation broth.…”
