Nano emulsions, methods of forming the same and uses thereof

A method for preparing a stable oil-in-water nano emulsion comprising: (a) combining one or more emulsifiers with oil and water to form a pre-mix; (b) forming a coarse emulsion from the pre-mix of step (a); and (c) forming a nano emulsion from said coarse emulsion, where the emulsifier(s) have an HL...

Beschreibung
Zusammenfassung:	A method for preparing a stable oil-in-water nano emulsion comprising: (a) combining one or more emulsifiers with oil and water to form a pre-mix; (b) forming a coarse emulsion from the pre-mix of step (a); and (c) forming a nano emulsion from said coarse emulsion, where the emulsifier(s) have an HLB (hydrophilic-lipophilic balance) value of 3-16, and step (c) comprises the use of ultrasound. The emulsifier may be a lipid soluble emulsifier with an HLB value of 3-5, and is preferably lecithin. The emulsifier may be a water soluble emulsifier with an HLB value of 12-16, and is preferably Tween-40 (RTM). Preferably, the method comprises the use of both a lipid soluble emulsifier and a water soluble emulsifier. The oil is preferably a long chain omega-3 polyunsaturated fatty acid (LC3PUFA). Also claimed is the use of an LC3PUFA containing emulsion in food products, nutritional supplements, pharmaceutical products, and cosmetic and body care products. Also claimed is a high yield method for extraction of an oil phase from an oil-in-water nano emulsion comprising the step of subjecting the nano emulsion to desiccation.
