Nanofiber-based Food Preservation Solution

Nanofiber-based Food Preservation Solution

Nanofibers have a small diameter and high surface area, which can release active agents in time and prevent bacteria from entering, so they have received extensive attention in the field of food preservation. Aprofood has deeply explored the field of food nanomaterials, and is committed to providing global customers with comprehensive food preservation solutions based on nanofiber.

Overview of Nanofibers

Nanofiber is a kind of linear material with a certain aspect ratio, whose diameter is nanometer and length is large. Its large surface area endows it with a unique function of "activity". Nanofibers can be used to produce active packaging with antibacterial effect, and can be endowed with certain slow release function. In edible coatings, nanofibers can be embedded in bioactive materials, such as plant extracts, antioxidants, antibacterial agents, etc.

Nanofibers can be arranged in two forms: a) aligned, b) random. Compared with the form of random distribution, the aligned form shows better physical and chemical properties. In edible coatings, alignment is advantageous because cells and nanofibers are aligned in each other's direction, and this structure directly leads to the formation of targeted extracellular matrix.

Applications of Nanofibers in Food Preservation

Food Packaging

Food Packaging

Nanofiber material packaging stands out for its large specific surface area, high porosity, anti-bacterial and anti-oxidation properties and degradability. It can develop anti-bacterial packaging, anti-oxidation packaging and high temperature and humidity resistant packaging.

Food Packaging

Food Filters

In order to improve the taste of liquid food, such as fruit juice and beer, and extend their storage time, suspended solids, bacteria, pectin and crude protein that may cause their deterioration must be removed. Nanofiber membrane is a material suitable for filtering fine particles.
