چکیده

رزین‌های اپوکسی بر پایه بیسفنول آ(BPA) کاربرد گسترده‌ای در مواد در تماس با مواد غذایی مانند پوشش‌های قوطی فلزی دارد. اثرات سوء بیسفنول آ برای مصرف کننده، صنعت بسته بندی مواد غذایی را به سمت ارتقاء ایمنی به طور مداوم سوق داده است. در این مطالعه ، پوشش اپوکسی تولید شده با نانوذرات به منظور شناسایی مهاجرت بیسفنول آ دی گلیسیدیل اتر (BADGE) تحت آزمون مهاجرت قرار می‌گیرد. مهاجرت BADGE از نانوکامپوزیت اپوکسی/ دی اکسید تیتانیوم/ اکسید آلومینیوم به مشابه‌های غذایی 10 درصد اتانول (حجمی-حجمی) ، 20 درصد اتانول (حجمی-حجمی)، 95 درصد اتانول (حجمی-حجمی) و 3 درصد اسید استیک (وزنی-حجمی) مشابه شرایط پر شدن (60 دقیقه در دمای 60 و 121 درجه سلسیوس) و شرایط نگهداری (10 روز در دمای 40 درجه سلسیوس) مطالعه شد. کروماتوگرافی مایع با کارایی بالا (HPLC) برای تعیین سطح مهاجرت بیسفنول آ دی گلیسیدیل اتر از نانوکامپوزیت به مشابه‌های غذایی استفاده شد. نتایج حاصل از این بررسی نشان داد که سطح مهاجرت بیسفنول آ دی گلیسیدیل اتر از نانوکامپوزیت اپوکسی/ دی اکسید تیتانیوم/ اکسید آلومینیوم به مشابه‌های غذایی در شرایط مشابه پرکردن و نگهداری از محدوده مجاز تعیین شده کمتر بود.

چکیده [English]

Bisphenol A (BPA)-based epoxy resins are widely used in food contact materials such as metal can coatings. The adverse effects of bisphenol A on the consumer have led the food packaging industry to continually improve safety. In this study, epoxy coatings manufactured with nanoparticles are subjected to migration testing in order to identify bisphenol A diglycidyl ether (BADGE) migration from the coatings. Migration of BADGE from epoxy/TiO2/Al2O3 nanocomposite into ethanol 10% (v/v), ethanol 20% (v/v), ethanol 95% (v/v), and acetic acid 3% (w/v) food simulants was studied at conditions of contact filling (60 min at 60 and 121°C) and storage condition (10 days at 40 °C). High-performance liquid chromatography (HPLC) was developed to determine the level of bisphenol A diglycidyl ether (BADGE) that migrated from the nanocomposite to the food simulants. The results indicated the levels of BADGE migrating from epoxy/TiO2/Al2O3 nanocomposite to the food simulants under the conditions of contact filling and storage did not exceed the specific migration limits.
