Investigation of the use of produced nanofibers from polymeric compounds by electrospinning for food coating

The use of bioactive materials in food packaging materials is improving today with the development of technology and demand and consumer awareness. The use of bioactive compounds such as antioxidants and antimicrobial compounds in active packaging preserves the natural properties of food products. These bioactive compounds can be incorporated into the polymers as coatings and protecting nutrients by various methods. Electrohydrodynamic processes namely electrospinning is novel technology which can produce nanofibers and microfibers in dried form in one step process. It is a suitable process for encapsulation of bioactive compounds such as phenolics compounds, antioxidants and probiotics. Additionally, electrospinning process is an easy method and inexpensive. Nanofibers have high porosity and specific surface area, also increase shelf life and preserve food quality through encapsulated bioactive materials. Various polymers are used in coatings and edible films, which mostly comprising two classes of proteins and polysaccharides (biopolymers). Considering the advantages of this method, it is possible to use a variety of biopolymers to encapsulate a wide range of nutritional and bioactive compounds in the food and packaging industry to enhance the protection and quality of food products. Hence, this study because of the importance of the edible compounds and biopolymers used in the coatings, films and packaging in the quality and shelf life of the foodstuffs is investigated.
