Cellulose Nanocrystals as 'Green' Emulsifiers Stabilized Crude Oil in Water Emulsions
This study examines the ability of CNC to stabilize crude o/w Pickering emulsions. The effects of concentration of CNC, ionic strength of the aqueous phase, volume fraction of crude oil to water, and the presence of divalent ions on the stability of crude o/w emulsions were examined. Emulsions …

Sensory Perception of Saltiness and Bitterness in Oil-in-Water Emulsions
… objective of this research was to evaluate saltiness and bitterness perception in oil-in-water emulsion systems. For that purpose, three experiments were performed: A sensory threshold study, a descriptive sensory and physical property evaluation, and a psychophysical assessment of taste …

T2 Characterization of Oil-In-Water Emulsions for NMR Sensor Applications
… essential aspect of healthcare with implications in chronic conditions such as renal disease and congestive heart failure. Current fluid status determination techniques lack quantitative methods and standards. Our research explores a point-of-care approach through a portable single-sided magnetic …

Effect of composition on empirical stability trends for oil-in-water emulsions
Relative stabilities of paraffin oil-in-water emulsions were determined empirically as a function of increasing ionic strength, surfactant type or concentration, droplet size, pH and calcium(II) concentration. Stabilities were measured by droplet size changes, planar interface oil droplet …

Fabrication of Electrospun Anti-fouling Membranes for Emulsified Oil-in-Water Separation
The separation of emulsified oils from water represents a significant challenge for water reclamation and clean-up, because such droplets remain suspended for long periods of time. Membrane technology offers a solution to such separations, but their major drawback is the requirement for frequent …

Evaluation of Xanthan/Enzymatically Modified Guar Gum Mixtures in Oil-in-Water Emulsions
<p>Oil-in-water emulsions have wide range of applications in food industry because of their structure-forming properties, and as delivery systems of polyunsaturated fatty acids into foods. The thermodynamic instability of oil and water, and high susceptibility of unsaturated fatty acids to …

The structure and kinetics of oil-in-water microemulsions stabilised by nonionic surfactants
… thesis is concerned with the behaviour of the single phase (10) alkane oil-in- water (01W) microemulsions stabilised by nonionic surfactants of the general structure H-(CH2)n(OCH2CH2)m-OH, abbreviated to CnEm. The aims were to attempt to characterise their behaviour in terms of the effect of the …

Metal oxide modified tubular ceramic membrane for the separation of oil-in-water emulsion.
Separating lower concentrations of oil-in-water (O/W) emulsion (< 250 mg/l) and smaller oil droplet size (< 20 μm) has been an industry challenge using conventional methods, including adsorption, electrocoagulation, flocculation, bioremediation, centrifugation, membranes, etc. This is mostly due to …

Preparation and Evaluation of Oil-in-Water Self-Nanoemulsifying Systems with Potential for Pulmonary Delivery
Self-Nanoemulsifying Drug Delivery Systems (SNEDDS) are mixtures of oil, surfactant and cosolvent/cosurfactant, which emulsify under conditions of gentle agitation. SNEDDS can drastically improve absorption of poorly water soluble drugs by keeping it in solubilized form at the site of absorption. …

Impact of ingredient interactions on the physico-chemical stability of milk protein-stabilised oil-in-water emulsions
Besides an oil phase and an aqueous phase, emulsions also contain an emulsifier (e.g. protein). In addition, most food emulsions contain other ingredients, which are intended to adjust the macroscopic appearance, rheology or gravitational stability. Thickeners are used to slow down creaming or …

Development of Hybrid Meat Products by Replacing Animal Fats with Faba bean Protein Isolate-Stabilized Canola Oil-In-Water Emulsion Gel
This thesis investigated the role of faba bean protein isolate-stabilized canola oil-in-water emulsion gel as a suitable animal fat replacer in meat products (pork bologna and beef burger). Emphasis was given to converting the viscous emulsion into a strong, self-supporting viscoelastic gel by …

Effects of Xanthan/Locust Bean Gum Mixtures on the Physicochemical Properties and Oxidative Stability of Whey Protein Stabilized Oil-In-Water Emulsions
<p>Scientific evidence shows that dietary intake of the omega-3 polyunsaturated fatty acids is beneficial to human health. Fish oil is a rich source of omega-3 fatty acids. However, fish oil with high levels of omega-3 PUFA is very susceptible to oxidative deterioration during storage. The …
