Eugenol nanoemulsions were prepared using gum arabic and lecithin as natural emulsifiers.
Ethanol was proved to be an effective co-surfactant to reduce droplet size of nanoemulsion.
The preparation method and physicochemical properties of eugenol nanoemulsions were comprehensively characterized.
Nanoemulsions showed similar antimicrobial activity compared to free eugenol.
Nano-size ultrafine powder of nanoemulsions produced by Nano Spray Drying technology exhibited better morphological properties and redispersibility than Freeze Drying technology.
