“…A sharp decline in flow was observed during the first few minutes, followed by a decrease in drop rate and a tendency to stabilize; this was similar to the flow behavior observed by Pagliero et al (2007). This behavior can be attributed to the retention of the phospholipid agglomerates in the membrane pores, and the high wax content present in the rice bran oil (5.3 to 6.2%), which may lead to an increase in the deposited layer on the membrane surface and result in clogged pores (Orthoefer, 2005;Pagliero et al, 2007).…”

SUMMARY:Membrane technology has been gaining momentum in industrial processes, especially in food technology. It is believed to simplify processes, reduce energy consumption, and eliminate pollutants. The objective was to study the performance of polyvinylidene fluoride (PVDF) and polyethersulfone (PES) polymeric membranes in the degumming of the miscella of crude rice bran oil by using a bench-scale tangential filtration module. In addition, oil miscella filtration techniques using hexane and anhydrous ethyl alcohol solvents were compared. All membranes showed the retention of phospholipids and high flow rates. However, the best performance was observed using the 50-kDa PVDF membrane in miscella hexane solvent, with a 95.5% retention of the phosphorus concentration (by a factor of 1.4), resulting in a permeate with 29 mg·kg −1 of phosphorus and an average flow rate of 48.1 L·m −2 ·h −1 . This technology can be used as a low-pollution, economical alternative for the de-gumming of crude rice bran oil, being effective in the removal of hydratable and non-hydratable phospholipids, resulting in oils with a low phosphorus content.

La tecnología de membrana ha ido ganando impulso en los procesos industriales, especialmente en tecnología de los alimentos. Se piensa que simplifica los procesos, reduce el consumo de energía, y elimina contaminantes. El objetivo fué estudiar el rendimiento de las membranas poliméricas de fluoruro de polivinilo (PVDF) y poliéter-sulfona (PES) en el desgomado de miscelas de aceite de salvado de arroz crudo, mediante el uso de un módulo de filtración de escalado tangencial. Además, se compararon las técnicas de filtración de miscelas de aceite, utilizando como disolventes hexano y alcohol etílico anhidro. Todas las membranas mostraron retención de los fosfolípidos y altas tasas de flujo. Sin embargo, se observó un mejor rendimiento usando la membrana de PVDF de 50-kDa con hexano como disolvente, con una retención del 95,5% de la concentración de fósforo (por un factor de 1,4), dando como resultado un permeado con 29 mg·kg −1 de fósforo y un promedio tasa de 48,1 L·m de fluido. Esta tecnología se puede considerar como de baja contaminación y una alternativa económica para el desgomado de aceite de salvado de arroz crudo, siendo eficaz en la eliminación de los fosfolípidos hidratables y no hidratables, resultando unos aceites con un bajo contenido en fósforo.

“…Water and acid degumming are two main methods which were applied by the oil industries (Ribeiro et al, 2008). Pagliero et al (2007) used membrane separation as an alternative process for oil degumming. They mentioned that membrane separation is a potential process compared to conventional degumming processes (Pagliero et al, 2007).…”

“…Since phospholipids are amphoteric molecules, they form reverse micelles in the medium with a molar mass above 20 kDa and molecular size from 20 to 200 nm (Koseoglu, 2002;Ribeiro et al, 2008). Ultrafiltration can thus be used to separate them from the oil-hexane mixture (Pagliero et al, 2007).…”

“…Recent research on the application of membrane technology to vegetable oils has mainly targeted desolventization (Koseoglu, Lawhon, & Lusas, 1990;Kwiatkowski & Cheryan, 2005;Ribeiro, Moura, Gonçalves, Petrus, & Viotto, 2006); deacidification (Kale, Katikaneni, & Cheryan, 1999;Manjula & Subramanian, 2006;Zwijnenberg, Krosse, Ebert, Peinemann, & Cuperus, 1999); degumming (García, Álvarez, Riera, Álvarez, & Coca, 2006;Kim, Kim, Lee, & Tak, 2002;Koris & Marki, 2006;Marenchino, Pagliero, & Mattea, 2006;Moura, Gonçalves, Petrus, & Viotto, 2005;Pagliero, Mattea, Ochoa, & Marchese, 2007;Subrahmanyam, Rao, Balasubrahmanyam, & Bhowmick, 2006); the synthesis and purification of structured lipids (Moura, Gonçalves, Sarmento, & Petrus, 2007;Moura, Ribeiro, Grimaldi, & Gonçalves, 2007;Xu, Balchen, Jonsson, & Adler-Nissen, 2000); the separation of compounds present in trace amounts in the oil such as antioxidants, and the removal of pigments.…”
