Applying Nanoemulsions to the Food Sector

Nanoemulsions are a relatively new technology that has found significant use for delivering functional chemicals such as micronutrients, flavorings, bioactive molecules, and antimicrobial agents into food and beverage products. This article focuses on applying nanoemulsions for sustainable food processing and packaging in the food sector.

What is a Nanoemulsion?Nanoemulsions (NEs) are non-equilibrium dispersions of at least two immiscible liquids (oil and water) with droplet sizes of 10–100 nm that are kinetically stable. These nanoemulsions have revolutionized the pharmaceutical, healthcare, skincare and food businesses. They have several remarkable properties, including small droplet size, transparency, enhanced surface area, and reduced sensitivity to chemical and physical changes, making them ideal for food formulations.

Components for the Formation of NanoemulsionsCore-shell architecture may be used to describe nanoemulsions, and it is made up of three phases: an oil phase (lipophilic), an aqueous phase (amphiphilic), and a surfactant (emulsifier/stabilizer) in precise proportions.

The features of the phases and surfactants should be considered when making nanoemulsions. Surfactants must be carefully selected to achieve an ultra-low interfacial tension (
