چکیده

پنیر لیقوان از جمله معروف‌ترین پنیرهای ایرانی است که به دلیل روش‌های سنتی تولید همواره با مشکلات میکروبیولوژیکی فراوانی همراه است. در این پژوهش اثر بسته‌بندی با دو فیلم نانوکامپوزیت پلی‌اتیلن سبک حاوی نانوذرات نقره، اکسید مس و اکسید روی با درصدهای متفاوت بر افزایش عمر نگهداری پنیر در دمای C° 4 بررسی شد. آزمون‌های میکروبی پنیر بسته‌بندی شده در بسته‌های فوق‌الذکر بلافاصله پس از تولید، 7، 14، 21، 28 و 60 روز پس از تولید صورت گرفتند. نتایج نشان دادند که بعد از 60 روز نگهداری سرعت رشد کلی‌فرم و استافیلوکوکوس‌اورئوس در پنیر تازه، با استفاده از فیلم ترکیبی حاوی درصد‌های مساوی از نقره، اکسید مس و اکسید روی (نمونه شماره 1) نسبت به سایر فیلم‌ها به صورت معنی‌داری (05/0p<) کمتر است. در صورتی‌که تاثیری بر روند کلی تغییرات باکتری‌های اسیدلاکتیک نداشتند. نتایج آزمون مهاجرت نانوذرات فلزی از بسته‌‌های حاوی نانوذرات فلزی به مشابه ماده غذائی نیز با توجه به استانداردهای اتحادیه اروپا و اداره غذا و داروی آمریکا بر ایمن بودن استفاده از نانوکامپوزیت‌های حاوی نانوذرات فلزی دلالت داشتند. همچنین مدل‌سازی مهاجرت برای نانوذره نقره در مدت 12 ماه نیز صورت گرفت.

چکیده [English]

Lighvan cheese is one of the most popular Iranian cheeses that always faces to microbial problems due to traditional ways of production. In this study the effect of two types of low density polyethylene-nanocamposite films contains of Ag, CuO and ZnO nanoparticles with different percentage increasing the shelf-life of chesse in 4̊C was investigated. Microbial tests of the packed cheeses were done immediately after packaging (at day 0) and after 7, 14, 21, 28 and 60 days of storage. After 60 days storage, the growth rate of Coliforms and Staphylococcus aureus significantly decreased (p<0.05) as a result of application of nanocomposite package containing equal percentage of nanometals (sample 1) but it did not affect Lactic acid bacteria's growth. The results of migration tests of nano metal particels from packaging in to food simulant showed that nano composite contain metal nanoparticle is safe according to limitation set by FDA and EFSA. Also migration modeling for nano silver in 12 months have done.
