“…Yang et al (2013) also observed that tinier droplets can be produced at higher concentrations of Tween 80 (HLB 15.0). Also, Van der Graaf et al (2005) reported that high concentration of emulsifier can improve the emulsion stability. Therefore, it is indicated in the present study that 10% concentration of PSML can be sufficiently effective to produce W/D/W nanoemulsion of red ginseng extract.…”

The aim of this study was to optimize conditions for producing water-in-oil-in-water (W/D/W) nanoemulsion and spray-dried nanocapsule of red ginseng extract. Based on emulsion stability and average particle size analysis, optimum conditions to produce W/D/W nanoemulsion were: ratio of core to coating material, 3:7; primary emulsifier, 10% polyglycerol polyricinoleate; ratio of W/D phase to coating material, 1.5:8.5; secondary emulsifier, 10% polyoxyethylene sorbitan monolaurate; solvent, 20% ethyl acetate; secondary coating material, 10% maltodextrin (MD). Under these optimized conditions, particle size of spray-dried nanocapsules coated with MD of red ginseng ranged from 100 nm to 500 nm, based on response surface methodology with the highest yield (up to 99.7%). Results of the present study can be used to further optimize conditions to produce W/D/W nanoemulsion and spray-dried nanocapsule of red ginseng extract.

“…43,[50][51][52][53][54][55] Unlike single emulsions, whose stability can be inferred from changes in their droplet size distribution alone, the stability of double emulsions is additionally characterized by the amount of inner droplet phase retained within the outer droplet phase, i.e., the encapsulation efficiency. 53 Most studies of encapsulation efficiency have been in W/O/W emulsions, where efficiency is typically measured either by encapsulating a water-soluble molecular probe (e.g.…”

Multiple emulsions have received great interest due to their ability to be used as templates for the production of multi-compartment particles for a variety of applications.However, scaling these complex droplets to nanoscale dimensions has been a challenge due to limitations on their fabrication methods. Here, we report the development of oil-in-water-in-oil (O1/W/O2) double nanoemulsions via a two-step high-energy method, and their use as templates for complex nanogels comprised of inner oil droplets encapsulated within a hydrogel matrix.Using a combination of characterization methods, we determine how the properties of the nanogels are controlled by the size, stability, internal morphology, and chemical composition of the nanoemulsion templates from which they are formed. This allows for identification of 2 compositional and emulsification parameters that can be used to optimize the size and oil encapsulation efficiency of the nanogels. Our templating method produces oil-laden nanogels with high oil encapsulation efficiencies and average diameters of 200-300 nm. In addition, we demonstrate the versatility of the system by varying the types of inner oil, the hydrogel chemistry, the amount of inner oil, and the hydrogel network crosslink density. These non-toxic oil-laden nanogels have potential applications in food, pharmaceutical, and cosmetic formulations.

“…Another interesting novel approach in membrane emulsification is the formation of drops through fragmentation of the dispersed phase in the lumen of hollow fibre membranes due to permeation of pure continuous phase through the membrane [6]. The main application areas of membrane emulsification are production of double emulsions [4][5][7][8], creation of drops for biphasic enzymatic reactions [9], and production of solid microparticles [10], such as solid lipid microcapsules [11], polymeric microspheres [12], silica particles [13], and gel microbeads [14].…”
