Nanoemulsions in food: market demand

Nanoemulsions are known to induce thermodynamically stable, less viscous, transparent, and isotropic dispersions made up by stabilising water and oil phase using emulsifiers. Emulsions with particle size of 5–100 nm are classified as nanoemulsions. These nanoemulsions have found applications in various industries such as food, agriculture, pharmaceutical, environment, and oil recovery. The applications of nanoemulsion in various food products have generated a huge market demand, which has been estimated to grow rapidly with consumer preference. The applications of nanoemulsions in various food industries is discussed in this review, emphasising on market demand and commercial application.
