Preparation of solution blow spinning nanofibers and its application in the food field: a review

Abstract

Solution blow spinning is a technology that uses high-pressure gas to prepare spinning solution into nanofibers. It has the advantages of high production efficiency and easy operation, and the prepared nanofibers have a large specific surface area, high porosity, and flexible surface functionalization. Therefore, solution blow spinning has received more and more attention in the food field. This paper first introduces the principle of solution blow spinning, the influence of spinning liquid properties, process parameters, and environmental factors on the spinning process. Secondly, it introduces the materials and ways of applying solution blow-spun nanofibers in the food field, such as bacteriostatic food packaging, slow-release food packaging, and intelligent sensors. Finally, the application of solution blow spinning technology in food is summarized and prospected. This paper provides a reference for further research and application of solution blow spinning in the food field at a later stage.
