چکیده
هدف این پژوهش. تولید فیلم از موسیلاژ گل پنیرک اصلاح شده با شیرین‌بیان (0، 3، 6 %) (وزنی/ وزنی) و نانوذرات سولفات مس (0، 2، 4 %) (وزنی/ وزنی) بود. برای مطالعه خواص ضخامت، رطوبت، حلالیت، نفوذپذیری به بخار آب، رنگی و خواص مکانیکی فیلم‌ها مورد استفاده قرار گرفت. نتایج نشان می‌دهد که با افزایش شیرین‌بیان و نانوذرات سولفات مس، میزان ضخامت فیلم افزایش می‌یابد. رطوبت، نفوذپذیری بخار آب و حلالیت فیلم با افزایش نانوذرات سولفات مس کاهش و با افزایش شیرین‌بیان افزایش می‌یابد. همچنین با افزایش غلظت شیرین‌بیان، شاخص‌های رنگی a*، افزایش یافته و روشنایی لایه‌ها به‌طور معنی‌داری کاهش یافت. نتایج آزمایش مکانیکی نشان داد که با افزایش شیرین‌بیان و نانوذرات سولفات مس، مقاومت کششی کاهش و افزایش نانوذرات سولفات مس ازدیاد طول در نقطه شکست به طور چشمگیری افزایش یافت. نتیجه‌گیری نهایی: افزودن ریشه شیرین‌بیان و نانوذرات سولفات مس به فیلم‌های خوراکی بر پایه موسیلاژ گل پنیرک سبب بهبود ضخامت و ازدیاد طول در نقطه شکست فیلم‌ها، همچنین موجب تضعیف مقاومت کششی، رطوبت، نفوذپذیری به بخار آب و روشنایی گردید.

چکیده English

The aim of this research was to produce a film from the mucilage of Paneerak flower modified with Shirin-Bian and copper sulfate nanoparticles. 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 sodium chloride. Also, with an increase in the concentration of Shirin Bayan, the color indices a* increased and the brightness of the layers decreased significantly. The results of the mechanical test show that with the increase of sugar and copper sulfate nanoparticles, the tensile strength decreases and with the increase of copper sulfate nanoparticles, the elongation at the breaking point increases significantly.
