چکیده

در این تحقیق، اثر ترکیب دو سطح کتیرا (15 و 30 %) بر فیلم کیتوزان 2% مورد مطالعه قرار گرفت و خصوصیات فیلم تولیدی بررسی شد. نتایج آزمون‌ها، بهترین خصوصیات را در غلظت 30% کتیرا در ترکیب با پلیمر کیتوزان به اثبات رسانید. درصد رطوبت و حلالیت فیلم با افزودن کتیرا به کیتوزان افزایش معنی‌داری نداشت (05/0<p). میزان نفوذپذیری به بخار آب در فیلم شاهد (کیتوزان) و فیلم کامپوزیت اختلاف معنی‌داری با یکدیگر داشتند (05/0>p)، کم‌ترین میزان در کامپوزیت 15% مشاهده شد که 53/1 (10-10 g/ms Pa) بود. مقاومت کششی فیلم کیتوزان با افزودن کتیرا تغییر معنی‌داری نداشت (05/0<p) ولی کم‌ترین مقاومت کششی در کامپوزیت 15% مشاهده شد. درصد افزایش طول با افزودن کتیرا کاهش یافت. افزودن کتیرا به فیلم کیتوزان تغییر معنی‌داری (05/0<p) در شفافیت آن ایجاد نکرد، اما از درجه شفافیت کاسته شد. به‌طوری‌که کم‌ترین شفافیت در کامپوزیت 30% مشاهده گردید. نتایج تحقیق حاضر نشان میدهد که افزودن کتیرا به کیتوزان باعث بهبود ویژگی‌های فیزیکی و مکانیکی این پلیمر در حالت فیلم و افزایش کارایی جهت بسته بندی ماهی گردد.

چکیده [English]

In this research, the combination of two levels of tragacanth gum (15 and 30%) on chitosan film 2 % were studied and produced film characteristics checked out. The results are proved the best properties in tragacanth 30% in combination with chitosan. Moisture and solubility was not significantly increased by adding tragacanth to chitosan (p>0.05). There was a significant difference between water vapor permeability of chitosan (control) and composite (p-1 s-1 p-1. Tensile strength of chitosan did not change significantly with the addition of tragacanth (p>0.05) but the lowest tensile strength showed in the composite 15%. Elongation percentage was reduced by addition of tragacanth. Add tragacanth to chitosan did not cause significant changes in its transparency (p>0.05) but the degree of transparency was reduced, so that the lowest transparency was observed in the composite 30%. The results of the present study demonstrated that the addition of tragacanth into the chitosan improve the physical and mechanical properties of this polymer in the film and increase its efficiency for fish packaging.
