Antioxidant Effect of Vitamins in Olive Oil Emulsion

In this study water-in-extra olive oil emulsions were enriched with vitamins Water-in oil emulsions are heterogeneous systems able to solubilize both hydrophilic and hydrophobic compounds Thus hydrophilic vitamin C and lipophilic vitamin E were loaded separately or together in emulsion A suitable emulsion composition was selected after considering different surfactant (mono and

Emulsion Types

In an oil-in-water emulsion the continuous phase is the water and the dispersed phase is the oil while in a water-in-oil emulsion the oil is the continuous phase Counterintuitively the type of emulsion does not depend on the actual amounts of oil and water present in an emulsion For example vinaigrettes are oil-in-water emulsions even though there is more oil in a vinaigrette than water

EFFECTS OF FUNCTIONAL GROUP OF NON

An emulsion is defined as a system consisting of two or more liquid immiscible phases which the droplets of one of the liquid phase are dispersed in another immiscible liquid phase There are two types of simple emulsion which are oil in water (o/w) emulsion and water-in-oil (w/o) emulsion The oil in water emulsion consists of oil droplets
