7.1 Abstract Tuna oil-in-water emulsions containing droplets stabilized by lecithin-chitosan membranes were produced using a two-stage process. Corn syrup solids were added to the emulsions and then the emulsions were spray dried, which produced a powder consisting of smooth spheroid powder microcapsules (diameter = 5-30 μm) containing small tuna oil droplets (diameter <1 μm) embedded within a ...

Self-diffusion NMR is used to investigate monodispersed oil in water emulsions and the subsequent gel formed by removing the water through evaporation. The radius of the oil droplets in the emulsions is measured using a number of diffusion methods based on the measurement of the mean squared displacement of the oil, water, and tracer molecules. The results are consistent with the known size of ...

In this study, blueberry essential oil as a core material was microencapsulated with Inulin and β-cyclodextrin at a ratio of 1:5 (core: wall). Oil in water nano-emulsions were prepared by ultrasonic liquid processors and then transformed to encapsulate powder in spray dryer. Dried powder was stored at 4 ˚C in refrigerator for determining moisture, encapsulation efficiency and morphology prop...

Materials manufacturing industries seek efficient, economic, and sustainable compounds for stabilizing dispersed systems such as emulsions. In this study, novel, abundant biobased hydrocolloids spruce galactoglucomannans (GGM) and birch glucuronoxylans (GX) were obtained from a forestry biorefining process and characterized as versatile stabilizers of rapeseed oil-in-water emulsions. For the fi...

Emulsification method is one of the popular methods for producing materials used inbiosensing, bioimaging and others, especially, drug delivery polymer systems in microsize andnanosize. The concrete techniques related to this are emulsification, self-emulsification,in a combination with solvent evaporation process, homogenization, or ultranosication. Thestructure emulsion formulation consists t...

The separation of oil from water in emulsions is a great environmental challenge, since oily wastewater is industrially produced. Here, we demonstrate a highly efficient method to separate oil from water in non-stabilized emulsions, using functionalized cellulose fiber networks. This is achieved by the modification of the wetting properties of the fibers, transforming them from oiland water-abs...

We report the preparation of highly transparent oil-in-water Pickering emulsions using contrast-matched organic nanoparticles. This is achieved via addition of judicious amounts of either sucrose or glycerol to an aqueous dispersion of poly(glycerol monomethacrylate)56-poly(2,2,2-trifluoroethyl methacrylate)500 [PGMA-PTFEMA] diblock copolymer nanoparticles prior to high shear homogenization wit...

The solubility of acid soluble soy protein (ASSP) is poor in the pH range of 4-7. ASSP-dextran conjugates were prepared through the Maillard reaction to increase the solubility and/or dispersibility of ASSP. By using the conjugates and ultrasonication emulsification, stable oil-in-water emulsions with submicrometer-sized droplets were obtained. The factors, such as ASSP conjugation degree, that...

To reveal the film formation mechanism of oil-in-water (O/W) emulsion, nanofilms of aqueous paraffin oil emulsion stabilized with the nonionic Tween 80 and Span 80 surfactants were measured in confinement between two solid surfaces, by the use of relative optical interference intensity (ROII) approach. In contrast to single-phase oil lubricant, the film formation of oil-in-water emulsions norma...
