چکیده

تمایل مصرف­کنندگان به استفاده از بسته­بندی زیست تخریب­پذیر مواد غذایی به جای انواع مصنوعی متداول آن افزایش یافته است. پلیمرهای زیستی به تنهایی یا به­صورت کامپوزیت و فعال در ساخت بسته­بندی­های جدید مورد استفاده قرار می­گیرند. تحقیق حاضر با هدف بررسی خصوصیات فیزیکی، مکانیکی و ضدمیکروبی فیلم مرکب فعال با 5 تیمار شامل فیلم پلی­وینیل الکل (P) به تنهایی، فیلم دوسازه­ای پلی­وینیل الکل و کیتوزان (PC)، فیلم سه سازه­ای پلی­وینیل الکل و کیتوزان و مونت­موریلونیت (PCM)، فیلم سه سازه­ای همراه با سطوح 2 و 4 درصد عصاره آویشن شیرازی (PCM Av) در قالب یک طرح کاملاً تصادفی اجرا شد. نتایج نشان داد افزودن کیتوزان، نانورس و عصاره آویشن به ترکیب فیلم پایه پلی­وینیل الکل توانست موجب بهبود خصوصیات فیزیکی، مکانیکی و ضدمیکروبی فیلم مرکب شود. فیلم مرکب PCM حاوی 4 درصد عصاره آویشن شیرازی با کدورت بالاتر نسبت به سایر فیلم­ها، دارای بیشترین مقاومت کششی و مدول یانگ (به­ترتیب MPa 10/30 و 14/0 مگاپاسکال)، بیشترین قطر هاله عدم رشد علیه باکتری­های استافیلوکوکوس اورئوس و اشریشیا کلی (به ترتیب mm 15/24 و 00/18) و کمترین نفوذپذیری در برابر بخار آب (gmm/m2 h Pa 90/3) بودند. بنابراین این فیلم کامپوزیت سه­ سازه­ای فعال با دارا بودن ویژگی­های مطلوب فیزیکی، مکانیکی و ضدمیکروبی، قابلیت بکارگیری به­عنوان ماده بسته­بندی زیست­تخریب­پذیر در صنایع غذایی را دارد.

چکیده [English]

The using biodegradable food packaging instead of its common synthetic types has been increased. Bio-polymers are used in the fabrication of new packages alone or as composite and active ones. The present study aims to investigate the physical, mechanical and antimicrobial properties of the active composite film with 5 treatments including polyvinyl alcohol: PVA (P) film alone, PVA and chitosan (PC), PVA/ chitosan and montmorillonite (PCM), PCM with 2 and 4% levels of thyme extract ( PCMAv) was carried out in a completely randomized design. The results showed that the addition of chitosan, nano clay and thyme extract to the composition of the PVA-base film could improve the physical, mechanical and antimicrobial properties of the composite film. PCM triple composite film containing 4% thyme extract with higher opacity than other films, has the highest tensile strength and Young's modulus (30.10 MPa and 0.14 MPa, respectively), the largest inhibitory zone diameter against Staphylococcus aureus and Escherichia coli (24.15 mm and 18.00 mm, respectively) and the lowest water vapour permeability (3.90 gmm/m2 h Pa). Therefore, this three-component active composite film, having desirable physical, mechanical and antimicrobial properties, can be used as a biodegradable packaging material in the food industry.
