“…and homogenization time was 30 s using a high-performance homogenizer (IKA Ultra-Turrax T-25 Digital Homogenizer) as showed in Figure-2 (Pratap-Singh et.al., 2021). The resulting nano-emulsion batches from both groups were transparent, monophasic, homogenous, stable liquid mixtures (Alhamdany et.2021;(Donsì et al, 2011;Zhang et al, 2021))…”

Background. The volatile oil present in star anise (Illicium verum) exhibits efficacy against various health issues such as bronchitis, colds, flu, indigestion, facial paralysis, and intestinal cramps. This study aimed to formulate and assess the nano-emulsion of star anise volatile oil. Method. Star anise volatile oil was extracted from its fruits using the Clevenger apparatus and subsequently purified. The extraction process involved dissolving the extracted oil in dichloromethane, and solvent recycling was performed using a rotavapor. Nano-emulsions were developed through homogenization (8 batches) and ultra-sonication methods (8 batches) with varying surfactant (Tween-80) and co-surfactant (PEG-200, PEG-300) ratios. Characterization involved refractive index, pH, Fourier transform infrared spectroscopy, particle size distribution, zeta potential, drug content, drug release, release kinetics, and stability studies (25°C/60% RH at 1, 2, 3, 4, and 5 weeks). Results. The smallest droplet sizes were observed in batches NE-HH (646.1±71.54 nm) and NE-HS (694±195.48 nm), with the least zeta potential values of -10.4 mV (NE-FH batch) and -5.2 mV (NE-HS batches). The highest drug release percentages were recorded in NE-EH (31.411±1.26%) and NE-ES (34.004±1.74%) batches. Both NE-EH and NE-ES followed the Peppas Korsmeyer model, and the release mechanism was identified as Fickian Diffusion (Higuchi Matrix). Conclusion. The study concludes that nano-emulsions of star anise volatile oil can be successfully prepared using homogenization and ultrasonication methods, demonstrating good stability and prolonged drug release.

“…The 6 mm probe was selected as it is appropriate for processing 10 mL of emulsion samples according to manufacturer's instruction. The sonication time (5s) was selected based on preliminary experiments and a previous study [8] so that 5 s is sufficient to form a homogeneous emulsion and the formed emulsion is not disrupted under prolonged sonication.…”

“…Therefore, the US treatment was employed to reduce the particle size ultrasonication and high pressure microfluidisation. Zhang, Luo [8] showed that the aggregated emulsion stabilised with MPC 70 can be formed by ultrasonication when the oil volume fraction ≥ 35%. In another study of formation of emulsions by ultrasonication, Li, Martin [2] demonstrated that stable aggregated emulsion gels can be formed by using various food and non-food particles such as bovine micellar casein and graphene oxide.…”

“…Due to an inferior aqueous solubility and large particle size of the QPI, various pretreatments such as high pressure homogenisation [8] or ultrasonication [17] were applied to reduce the particle size of QPI prior to the emulsification. Previous studies have demonstrated that the pH values exerted significant impacts on physicochemical properties and microstructural characteristics of protein stabilised emulsions [21,22].…”

Ultrasonication (20 kHz, 19.9 W/10 mL sample) was used to form O/W emulsions stabilised by quinoa protein isolate (QPI) particles at 3 wt%. Effects of pH (3, 5, 7, 9) and oil volume fractions (20%, 40%, and 60%) on rheological properties and microstructural characteristics of emulsions were investigated. All emulsions show viscoelastic behaviours and form a network structure comprising aggregated oil droplets and QPI particles. Emulsions stabilised by QPI at pH 5 showed largest droplet sizes and lowest gel strength due to extensive aggregation of proteins around the isoelectric point (pI ~ 4.5). The gel strength (G´(1 Hz)) were enhanced when the oil volume fraction increased and reached ~ 1100–1350 Pa at 60% oil volume fraction at different pH. This could be attributed to a tighter packing of oil droplets at 60% oil. Confocal laser scanning microscopy (CLSM) and transmission electron microscopy (TEM) revealed that interdroplets bridging and voids filling of QPI particles between oil droplets are critical in formation of aggregated emulsions network. Emulsions stabilised by QPI at pH 7 and 9 possessed thinner interfacial layers compared to those at pH 3 and 5. Finally, this study shows a potential of using ultrasonication to prepare gel-like emulsions stabilised by QPI, broadening applications of quinoa proteins in making dairy substitutes with semi-solid textural characteristics.

“…Oil-in-water emulsions stabilized by milk protein concentrate (MPC70) were investigated by Zhang et al [9] using skim milk with a varied amount of oil volume fraction to highlight dairy emulsions with tailored textures. They noticed high viscosity pseudoplastic material formation at ≥ 35% oil concentration and ≥ 3 s sonication times.…”

Formation by high power ultrasound of aggregated emulsions stabilised with milk protein concentrate (MPC70)

Abstract: Highlights Emulsions up to 65% oil and stabilised by 5% MPC70 were made by sonication (US) Under certain oil concentrations (≥35%) and US energies the emulsions gelled. Behaviour was explained by the bridging of the oil droplets by the MPC70 particles.
