Encapsulation stability of duplex emulsions prepared with SPG cross-flow membrane, SPG rotating membrane and rotor-stator techniques—A comparison

SPG rotating membrane technique for production of food grade emulsions

“…The limited number of publications on this subject mostly focuses on the stainless steel rotating membranes, which were used in the production of simple (and mostly coarse, Aryanti et al, 2006;Yuan et al, 2009) O/W emulsions, where rotational velocity, trans-membrane pressure, width of the gap, membrane pore geometry and emulsion composition were considered in relation to the microstructure of the emulsion. We have recently reported (Pawlik and Norton, 2012), that duplex W 1 /O/W 2 emulsions produced with the SPG rotating membrane have higher encapsulation properties than duplex emulsions made with the SPG cross-flow membrane. It has also been suggested (Charcosset, 2009), that amongst membrane techniques, the rotating membrane offers the advantage of increased disperse phase fluxes, which can be otherwise achieved by using an asymmetric membrane (Kukizaki and Goto, 2007).…”

Recent advances in the production of controllable multiple emulsions using microfabricated devices

“…3c), tubular vertical membrane moves within a static continuous phase periodically clockwise and counter-clockwise (Silva et al, 2015) or upward and downward (Holdich et al, 2010) with frequencies from 10 to 90 Hz and amplitudes from 0.1 to 7 mm to generate shear on the membrane surface. In rotating (spinning) ME systems, a tubular membrane rotates within a static continuous phase at the speeds ranging from 100-1500 rpm in laboratory systems (Pawlik et al, 2012;Yuan et al, 2009;Vladisavljević et al, 2006a;Aryanti et al, 2006) to 6000-10000 rpm in commercial MEGATRON ® devices (Graber et al, 2010).…”

High-pressure Homogenizer Design

“…In addition to DME with static SPG membrane, where shear stress is controlled by fluid flow over the membrane surface, dynamic SPG membrane systems have been investigated, where shear is controlled by rotating the membrane within a static continuous phase (Pawlik and Norton, 2012;. Rotating membrane systems can be operated batchwise or continuously.…”
