Nanoemulsion-based Food Preservation Solution

As a new type of food carrier, nanoemulsion has attracted extensive attention in food preservation. Aprofood deeply explores the field of food nanomaterials and is committed to providing global customers with comprehensive food preservation solutions based on nanoemulsion.

What are Nanoemulsions?

Nanoemulsions are colloidal dispersions of two incompatible liquids, typically oil and water in food applications, where one liquid is dispersed in the other in the form of fine droplets. Usually, the average droplet diameter of nanoemulsions is less than 200 nm (d<200 nm). The formulation of kinetically stable nanoemulsions requires at least three components: oil, water, and emulsifier. In the food industry, nanoemulsions often contain various other functional ingredients, such as colors, flavors, preservatives, nutrients, etc., depending on their intended use.

Application of Nanoemulsions in Food

Nanoemulsions can provide many benefits by wrapping bioactive compounds, such as essential fatty acids, vitamins, polypeptides, antioxidants, minerals and probiotics, covering them with protective wall materials, preventing the evaporation, chemical reaction or migration of active ingredients in food, providing controlled delivery, and maintaining their stability during processing and storage. Especially in recent years, the use of nanoemulsion as a carrier of antibacterial and antioxidant components in food preservation has received extensive research and attention.
