“…Similar behavior was noted by Kim et al [19], who studied the influence of three different concentrations of soybean oil in hexane during degumming by UF, using polyimide membranes with an MWCO of 20 kDa. The point at which the membrane separation process changes from the pressurecontrolled stage to the mass transfer-controlled stage is known as the critical pressure, which is considered as the suitable TMP for ideal membrane separation [20].…”

Deoiling of soy lecithin through ultrafiltration (UF) using an inorganic ceramic membrane was examined in a favorable solvent medium (hexane). Phospholipid (PL) reverse micelles with an average particle size of 9.8 nm were prepared in a 1:3 soy lecithin/hexane system (m/m) with 9% water added at a temperature of 25°C. Consequently, an inorganic ceramic membrane with a pore size of 5 nm was selected. UF was employed in continuous diafiltration mode at transmembrane pressure (TMP) of 0.25 MPa, and a final deoiled lecithin product with a high acetone insoluble (AI) content of 96.32% was obtained at a yield of around 84%.

“…Iwama [6] reported the degumming of oil-hexane miscella with a commercial tubular ultrafiltration (UF) membrane. Pagliero et al [7] evaluated the efficiency of membrane technology for degumming crude soybean oil-hexane miscella by use of a commercial polyamide membrane and a laboratory-made PVDF-based membrane. Raman et al [8] described a process for solvent recovery and partial solvent (methanol) deacidification from miscella by use of different commercial membranes.…”

Vegetable oil extraction, as performed today by the oilseed-crushing industry, usually involves solvent extraction with commercial hexane. After this step, the vegetable oil-hexane mixture (miscella) must be treated to separate its components by distillation. If solvent-resistant membranes with good permeation properties can be obtained, membrane separation may replace, or be used in combination with, conventional evaporation. Two tailormade flat composite membranes, poly(vinylidene fluoride) (PVDF-Si and PVDF-CA) and a commercially available composite membrane (MPF-50), were used to separate a crude sunflower oil-hexane mixture. The effects of temperature, cross-flow velocity (v), transmembrane pressure (Dp), and feed oil concentration (C f ) on membrane selectivity and permeation flux were determined. The PVDF-Si membrane achieved the best results, being stable in commercial hexane and having promising permselectivity properties for separation of vegetable oil-hexane miscella. Improved separation performance was obtained at C f = 25%, Dp = 7.8 bar, T = 30°C, and v = 0.8 m s -1 ; a limiting permeate flux of 12 Lm -2 h -1 and 46.2% oil retention were achieved. Low membrane fouling was observed under all the experimental conditions studied.

“…While the basics of the degumming process have been largely unchanged for several years, new membrane separation systems have been gaining recent attention (11). Past problems of plugging may be solved by new filter media, miscella filtration, or evolution of selfcleaning designs.…”

In the early days of oilseed production, functions were often far removed, and actions taken by one operation were done for optimization of its own performance with little consideration on impacts made on subsequent processes. Within the last few years, the emphasis has changed from stand‐alone operations toward the integrated manufacturing facility, producing a more complete range of value‐added products from the raw seed to the dinner table. During this transition, operations have become more dependent on each other, as the individual functions involved must now consider the impact of their actions on the total process. At the same time, the scope of knowledge each operation must have of other functions has expanded, and it is important that at least a basic understanding of the “big picture” be available to the decision maker. The purpose of this Chapter is to provide an overview of the typical processes and interrelations associated with a total integrated facility.
