| Summary: | Natural and biodegradable polymers are gaining prominence in the food packaging industry when compared with non-biodegradable petroleum-based materials. This transformation is assigned to their advantageous characteristics, encompassing a high protein content, substantial water absorption capacity, low surface tension, non-toxic nature, and broad availability. Persian gum (PG), is an exudate polysaccharide of Amygdalus Scoparia Spach which has recently attracted the attention of researchers thanks to its distinctive properties. This study is a comprehensive review of the current trends in PG-based edible films and coatings applied for food preservation. The findings of recent studies suggest excellent compatibility with other macromolecules, making them suitable for various food packaging and coating components. Herein, the recent techniques employed to develop the physical and functional properties of PG-based films are discussed, including modification of PG, incorporating plasticizers, blending with other biopolymers besides incorporation of nanoparticles, plant extracts, and essential oils. This review aims to clarify the physicochemical and structural characteristics of Persian gum as well as summarize results of recent studies concerning its applications as a novel hydrocolloid to be used in the composition of food packaging and coatings. |
