Zhang, Hong published the artcileMigration testing of metallized polypropylene films treated with ionizing radiation, Category: esters-buliding-blocks, the publication is Food Packaging and Shelf Life (2022), 100799, database is CAplus.
An UHPLC-QTOF/MS method was employed to identify chems. migrating from metalized polypropylene (met PP) films. The migration test was conducted by converting met PP films into pouches filled with 95% ethanol as a fatty food simulant and treating the pouch samples with gamma and electron beam irradiation at a dose of 10 kGy. A temperature of 22°C and a duration time of 21 days were used for the migration test. Over 10 chems. were identified, 3 of them were intentionally added substances (IAS), while the rest were considered as non-intentionally added substances (NIAS) including radiolysis products (RPs) derived from antioxidants. Based on the identification results, 5 chems. (3 hindered phenolic compounds, 1 phosphate compound and 1 phosphonate compound) were selected and their migration behaviors were evaluated under the effect of irradiation It was found that irradiation treatment significantly reduced the migration level of all substances. The extent of decrease was dependent on their stability under irradiation The phosphate/phosphonate compounds recorded higher stability resulting in less decrease (3-25%) in migration level. The hindered phenolic compounds were susceptible to irradiation and a large drop (45-88%) of migration level was observed Potential risks of met PP films were evaluated by comparing the migration levels of selected chems. with their migration limits either listed in Regulation (EU) Number 10/2011 or established with Cramer classification. The results showed that the migration level of the phosphonate compound was above the recommended migration limit, which may present a safety concern.
