What is Edible, Strong, and Low‐hygroscopic Bacterial Cellulose Derived from Biosynthesis and Physical Modification for Food Packaging about?

## Abstract ## Background The pervasive presence of plastic packaging has led to significant environmental contamination due to excessive reliance on petrochemicals and the inherent non‐biodegradability of these materials. Bacterial cellulose (BC) films present a viable alternative for food packaging applications, owing to their environmentally friendly synthesis process, non‐toxic nature, robust mechanical strength, and biodegradability. However, the high hygroscopicity of such bio‐based materials has limited their widespread adoption, as it results in diminished strength and barrier properties. In this study, a novel approach for creating edible, transparent, robust, and high‐barrier BC‐based composite packaging was proposed through biosynthesis with the incorporation of soy protein isolate and the physical interpenetration of calcium alginate‐polyethylene glycol as a composite coating. ## Results The finding demonstrated that the synthesized bio‐based composite material exhibits stability in water, high optical transparency, complete oil resistance, and full degradability within 1 to 2 months. Furthermore, the composite material displayed enhanced mechanical properties in both d
