“…The importance of increasing temperature in non-ionic surfactant is similar to the addition of electrolyte in anionic surfactant which has been proven to cause significant reduction in IFT between some vegetable oils and water in previous literatures [2,3]. Observation of the phase behaviour of CPO/Tween 80 solution at increasing temperature and different concentration of Tween 80 was conducted to investigate the existence of a phase inversion temperature (PIT).…”

“…From preliminary observation, the IFT reached equilibrium within 30 minutes to an hour. Therefore, the measurements were taken within this period [3]. All measurements for IFTs involving CPO were maintained at 60°C to prevent crystallisation [9].…”

“…The surfactant reduces the high interfacial tension (IFT), the surface energy exerted by intermolecular interactions, between two immiscible phases of oil and water [2]. An efficient aqueous surfactant extraction system usually has the ability to reduce the IFT value to an ultralow level (10 -3 mN/m) [3]. Previous researches have shown that ultralow value of IFT contributed to significantly high extraction efficiency and free oil recovery [2,3].…”

“…Extended surfactant, a special surfactant with unique structure of having groups of intermediate polarity in between hydrophilic and lipophilic group of the surfactant, acts like a linker or a bridge that will provide stronger interaction between the hydrophobic group of the surfactant and the hydrophobic oil as well as between hydrophilic group of surfactant and water. This strong interaction will contribute to IFT reduction to the ultralow level [2,3]. However, the health and safety aspects of extended surfactant in food processing application is uncertain.…”

Abstract. Surfactant-assisted aqueous extraction has been proposed as a "green" alternative to hexane extraction for the recovery of oil from plant matters. An efficient aqueous surfactant extraction system usually use an extended type of ionic surfactant with the ability to produce Winsor type III microemulsion, reducing the interfacial tension (IFT) between plant oil and surfactant solution to an ultralow level (10 -3 mN/m). However, the safe used of this surfactant in food processing is uncertain leading to non-food application of the recovered oil. In the present study, the potential of Tween 80, a commercial food-grade non-ionic surfactant, was evaluated in the recovery of residual oil from palm-pressed mesocarp. The emulsion produced between Tween 80 and crude palm oil (CPO) was characterised in terms of IFT, droplet size, viscosity and phase inversion temperature (PIT). The effect of surfactant concentration, electrolyte (NaCl) and temperature were studied to determine whether a Winsor Type III microemulsion can be produced. Results shows that although these parameters were able to reduce the IFT to very low values, Winsor type III microemulsion was not produced with this single surfactant. Emulsion of CPO and Tween 80 solution did not produce a PIT even after heating to 100°C indicating that middle phase emulsion was not able to be formed with increasing temperature. The highest percentage of oil extraction (38.84%) was obtained at the concentration above the critical micelle concentration (CMC) of Tween 80 and CPO, which was at 0.5 wt% Tween 80 with 6% NaCl, and temperature of 60°C. At this concentration, the IFT value is 0.253 mN/m with a droplet size of 4183.8 nm, and a viscosity of 7.38 cp.

An ethanol-assisted aqueous enzymatic extraction was performed for peony seed oil (content of 30%). This method included cooking pretreatment, pectinase hydrolysis, and aqueous ethanol extraction, and the corresponding variables in each step were investigated. The changes in viscosity and dextrose equivalent values of the reaction medium as a function of changing enzymatic hydrolysis time were compared to the oil yield. The microstructures of peony seeds were analyzed using confocal laser scanning microscopy to understand the process of oil release as a result of cooking and grinding. The highest oil yield of 92.06% was obtained when peony seeds were cooked in deionized water with a solid-liquid ratio of 1:5 (w/v) at 110 C for 1 hour, ground to 31.29 μm particle size, treated with 0.15% (w/w) pectinase (temperature 50 C, pH 4.5, time 1 hour), and then extracted with 30% (v/v) aqueous ethanol (temperature 60 C, pH 9.0, time 1 hour). After processing with pectinase followed by ethanol extraction, the residual oil content in water and sediment phase decreased to 5% and 3%, respectively. The quality of the oil obtained by ethanol-assisted aqueous enzymatic extraction was good, complying with the Chinese standard.Deshelled peony seeds were added to deionized water or 0.05 M citric acid solution at a solid-liquid ratio of 1:5 596 J Am Oil Chem Soc J Am Oil Chem Soc (2019) 96: 595-606 Fig. 6 Trends of viscosity and DE value during the pectinase hydrolysis.
