A comprehensive review of gum-based electrospun nanofibers for food packaging: Preparation, developments, and potential applications.

Gums represent an intriguing group of biopolymers utilized in the food industry owing to their exceptional properties. These intricate carbohydrate biomolecules possess the capacity to form gels and mucilage structures by binding with water. Their stabilizing potential, heightened viscosity, emulsifying characteristics, broad compatibility, and cost-effectiveness render them a valuable resource in the realm of food packaging. Electrospun nanofibers (ENFs) derived from gums offer an amplified surface-to-volume ratio in comparison to bulk materials at the macroscopic level, resulting in increased porosity and enhanced mechanical properties. These attributes have the potential to enhance surface functionalities and diversify their range of applications. Despite the limited availability of gum types for the synthesis of ENFs, extensive research has been dedicated to the advancement of gum-based ENFs and the exploration of their applications. This review paper delves into the influence of gum properties on solution spinnability and the prospective applications of gum-based ENFs in active and intelligent food packaging.
