“…Reverse micelles spontaneously form nanoscale aggregates and are thermodynamically stable. When used as a drug carrier, reverse micelles can enhance drug stability and bioavailability . Reverse micelles offer tunable degradation behavior for sustained drug delivery due to their liquid‐crystal structure, which retards drug dissolution .…”

Reverse micelles have good thermodynamic stability, small particle size, good self‐assembly performance, and controlled drug release versus other microparticle transdermal drug delivery systems. Here, a reverse micelles solution and a gel system formed by self‐assembly of insulin aqueous solution/lecithin/isopropyl myristate (IPM) were used for transdermal delivery of insulin. The size, size distribution, morphology and rheology of the reverse micelles were characterized with dynamic light scattering (DLS), small angle x‐ray scattering (SAXS), differential scanning calorimetry (DSC), viscosity measurement, and freeze fracture transmission electron microscopy (FF‐TEM). The findings suggested that lecithin/isopropyl myristate self‐assembled reverse micelles were spherical with uniform particle sizes (< 100 nm). The water in the reverse micelle was in the form of bound water, and the diameter of the water pool was about 4 nm. The reverse micelle solution and gel appeared as a pseudo‐plastic fluid. The gel was thixotropic, which benefits transdermal delivery.

“…Reverse micelle technology is based on microemulsion at surfactant concentration above the critical micelle concentration, which attracts much attention in food industry (Hong et al 2015). Reverse micelles are nanometer sized aggregates by forming the surfactants in a non-polar solvents mixed with water (Leser and Luisi 1989).…”

“…Reverse micelles are nanometer sized aggregates by forming the surfactants in a non-polar solvents mixed with water (Leser and Luisi 1989). The core part in the reverse micelles is water microdomain, which is surrounded by organic phase (Hong et al 2015). Some water-soluble compounds can be dissolved in the inner aqueous phase, such proteins and other biomolecules (Hong et al 2015;Zhou et al 2012).…”

Some water-soluble compounds can be dissolved in the inner aqueous phase, such proteins and other biomolecules (Hong et al 2015;Zhou et al 2012). The large-scale separations of proteins/or other biomolecules in reverse micelles had been preferred as a attractive approach because of its various advantages, including enormous interfacial area, thermodynamically stable and optically transparent, lower cost, ease of scale up and simple control of the reaction variables et al (Hong et al 2015;Sereti et al 2014).…”

“…The solution containing the proteins would be subsequently recovered from reverse micelles into a fresh aqueous solution during backward extraction (Leser and Luisi 1989). A number of investigations have indicated that many factors could affect the extraction yield of water soluble molecules in reverse micelles, such as nature and concentration of target proteins, pH and ionic strength et al (Hong et al 2015;Juang et al 2012). Recently, soybean proteins obtained through AOT reverse micelles was reported, which resulted in a reasonable advantage in the aspect of bioconversion efficiency (Chen et al 2014).…”

The work attempted to study on separating the a 0 , a and b subunits of 7S globulin from soybean proteins by reverse micelles. The effects of six single factors (W 0 , time, temperature, pH, surfactant concentration and salt solution species) on three subunit partitioning were discussed. The main influence factors (time, temperature and surfactant concentration) were optimized by the response surface test (Box-Behnken design, three factor three level) in order to optimize the forward extracting three subunits of 7S globulin. It was observed that the independent factor had substantial effect on the forward extraction yield of three subunits of 7S globulin. The statistical analysis showed that the reverse micelles could significantly affect the forward extraction efficiency of protein subunits. The highest forward extraction efficiency of a 0 , a and b subunits achieved 78.21, 63.65 and 61.34%, respectively. The proposed method also showed that the forward extraction efficiency of subunits with larger molecular weight was higher than low molecular weight.

Protein extraction from soybeans is a vital part of the soy industry. Traditionally, the extraction of soy protein has been done by alkaline extraction and isoelectric precipitation. With the advancement of technology, more extraction techniques have been developed, and are superior to this traditional method. In this review, the composition and classification of soy protein are summarized. Next, the current emerging technologies for soy protein extraction are highlighted. Three extraction technologies, namely reverse micellar, enzyme‐assisted and membrane ultrafiltration, are reviewed in detail. Finally, the research prospects and trends of soy protein extraction technology are also summarized.
