“…Campbell and Glatz [3] suggested that the unextracted oil in soybeans was trapped in the disrupted cellular matrix due to its large droplet size, while sodium dodecyl sulfate (SDS) could facilitate the breakup of large oil droplets by lowering the interfacial tension (IFT) and making the oil extraction possible. SDS was also applied for the extraction of canola oil, and the highest total oil yield was 80 % [11]. In addition to the use of conventional surfactant, a recently developed new class of surfactants known as extended-surfactants was also reported for the AEP oil extraction process [12].…”

To destabilize the emulsion formed during aqueous extraction processing (AEP) of peanuts, Tween and Span series surfactants (Tween 20, Tween 80, Span 20, and Span 80) were used alone or in combination to break the emulsion. Results indicate that only Tween surfactants had a pronounced demulsifying effect that was dependent on Tween concentration and system pH. When 1.2 wt% Tween 20 aqueous solution was used for oil extraction at pH 10.0, the highest free oil yield was achieved at 76.1 %, which was similar to the oil recovery of using proteases as a destabilization agent. The results obtained using a model emulsion system containing peanut oil and Tween 20/peanut protein isolates (PPI) showed that when Tween 20 and PPI coexisted in extraction medium at pH 10.0, the dynamic interfacial tension and droplet size distribution curves were very similar to those when Tween 20 was used alone, suggesting that Tween 20 dominated at the interface, instead of PPI. Destabilization of the model emulsions relied on three important factors: inclusion of Tween 20 at the initial mixing stage, high pH, and a gentle mixing speed. A synergistic destabilization mechanism of using Tween 20 at high pH during AEP was proposed. The discovery of Tween 20 as an effective demulsifier significantly contributes to the development of AEP of oilseeds.

“…The optimum extraction of the canola was also supported with the optimum extraction time needed which was 30 mins and above. This was due to the phenomenon of stable decrement of IFT readings observed after 30 mins of canola extraction from the previous study (Tuntiwiwattanapun et al, 2013). The IFT value is very important in promoting oil extraction whereby lower IFT value with low CMC will enhance oil liberation mechanism while using less surfactant, which is safer for the consumer as this, may avoid irritation and toxicity.…”

Passion fruit (Passiflora edulis) has a distinctive aroma and flavour and is widely commercialized as fruit juice. A high amount of seeds waste is produced during the juice production. The seeds contain high amounts of oil which can be extracted by hexane or pressing. However, hexane is a hazardous chemical, while pressing generally results in low yield of oil. In this study, surfactant-assisted aqueous extraction (SAAE) was explored to extract the oil at room temperature (25˚C) from the seeds by combining Tween 20 and Span 20 food-grade surfactants. It was determined that Hydrophilic-Lipophilic Balance (HLB 14 to 16) resulted in the lowest interfacial tension (IFT) between the oil and the surfactant solution. The extraction yield was found to correlate well with the interfacial tension whereby reduction in IFT causes an increase in the extraction yield. The highest extraction (80%) was found at 1% surfactant concentration which is at the critical micelle concentration (CMC) of the surfactant solution. The optimum parameter for extraction was 1:19 solid-liquid ratio, 15 mins extraction at 25°C. SAAE with food-grade surfactant can be a simple and viable technique to extract the waste passion fruit seed at low temperature, short time and low surfactant usage. The oil was found to contain phenols (26.3 mg GAE/g), squalene (0.65 mg/g), β-sitosterol (0.58 mg/g) and vitamin E (0.1 mg/ g). The main free fatty acids present were linoleic (65.72%), oleic (17.9%) and palmitic (11.41%).

“…Surfactants have been applied in aqueous extraction processing to improve vegetable oil recovery. Sodium dodecyl sulfate was used to improve recovery of soybean oil (Campbell and Glatz, 2009) and canola oil (Tuntiwiwattanapun et al, 2013) by extracting the oil trapped in disrupted cellular matrix. The extendedsurfactants, which is a recently developed new class of surfactants that works by significantly reducing the interfacial tension, extracted 93-95% of total oil from the insufficiently ground peanut and canola seeds (Do and Sabatini, 2010).…”

Distillers corn oil (DCO) is a valuable co-product of dry-grind corn ethanol process. It can be used for biofuel production and in animal feed. DCO can be present in different forms in the fermentation matrix, including oil adhering to solid surfaces such as cell wall and protein matrix, and oil contained in unbroken cells, which is difficult to partition to thin stillage by decanting. Effects of using surfactant (Tween® 80) and enzymes during fermentation on DCO partition to thin stillage and DCO recovery from the condensed corn distillers with solubles (CCDS) were investigated. There was more than 8 ∼ 10% DCO adhered to wet cake solids in whole stillage produced by conventional procedure, and this part of DCO was moved to thin stillage when 500 ppm of Tween® 80 was used during fermentation. Enzymes reduced the particle size of wet cake solids and released more DCO from wet cake to thin stillage. However, the use of protease reduced oil recovery (4.0% versus 7.9% and 17.9%, protease versus control and non-starch polysaccharide hydrolyzing enzymes) by producing partially hydrolyzed protein, which may have acted as emulsifier. Moreover, a synergistic effect between the use of enzymes and Tween® 80 was found on DCO partition in thin stillage and its recovery from CCDS
