Emulsions, such as creams, dressings and desserts, are an important part of the food industry and our daily lives. However, the food industry rarely explores non-aqueous systems such as oil-in-oil (O/O) emulsions due to the difficulty of finding suitable emulsifiers with hydrophobic nature and the few edible compounds available. Different from typical oil-in-water (O/W) and water-in-oil (W/O), O/O emulsions with little or no water can be utilized for the development of food products where water is not desired, such as encapsulation of water-insoluble bioactive and functional foods. The biggest challenge of this research is to achieve stability of non-aqueous emulsions. To achieve this objective, alternative solutions, such as using an electric field, have been proposed. The advantage of using oils instead of water is the low conductivity of oils, making them suitable and safe for treatment using electricity. This feature allows the use of solid particles as stabilizers, for what are often described as Pickering emulsions. This opens up possibilities for a new trend in food-grade emulsions, such as green-label products. Moringa is perhaps the most nutritious tree in the world, for it contains numerous nutrients and antioxidants in its oil and leaves. In a non-aqueous emulsion, it is possible to combine moringa and other oils to produce a new range of green-label products with desired and healthy properties. In this research, faster emulsification was achieved using an electric field. The multiple effects of electrohydrodynamics (EHD) on a non-aqueous droplet provided valuable insights into the application of food-grade non-aqueous emulsions.
