فیلم زیستتخریب پذیر برپایه موسیالژ گل پنیرک اصالح شده با شیرین بیان و نانو ذرات سولفات مس: بررسی خواص فیزیکوشیمیایی.

The aim of this study. The production of film was from the mucilage of the Paneerak flower modified with licorice (0, 3, 6%) and copper sulfate nanoparticles (0, 2, 4%). It was used to study the properties of thickness, humidity, solubility, permeability to water vapor, color and mechanical properties of the films. The results show that with the increase of licorice and copper sulfate nanoparticles, the thickness of the film increases. Humidity, water vapor permeability and solubility of the film decrease with the increase of copper sulfate nanoparticles and increase with the increase of licorice. Also, with the increase of licorice concentration, the color indices a* increased and the brightness of the layers decreased significantly. The results of the mechanical test showed that with the increase of licorice and copper sulfate nanoparticles, the tensile strength decreased and with the increase of copper sulfate nanoparticles, the elongation at the breaking point increased significantly. Final conclusion: Addition of licorice root and copper sulfate nanoparticles to edible films based on the mucilage of paneerak flower improved the thickness and increased length at the breaking point of the films, and also weakened the tensile strength, humidity, permeability to water vapor and brightness.
