Preparation and Characterization of Sunflower Oil-Based Emulsion Containing Vitamin E

Abstract

Vitamin E is known as antioxidant which inhibit the propagation of free radicals in preventing the various diseases associated with presence of free radicals. The stability of vitamin E has effects in lowering the bioactivity, and as Vitamin E is easily oxidized, it gives a negative impact on its efficacy. Sunflower oil contains oleic acid and linoleic acid which are associated with health benefits and can be used as the oil phase for the emulsion system to enhance the delivery of Vitamin E. However, emulsion is an unstable system as the liquids are immiscible and able to agglomerate. Thus, the present study was proposed to prepare and characterize a stable sunflower oil-based emulsion containing vitamin E.
