20.500.12556/DKUM-27310 Presence of nonylphenols in plastic films and their migration into food simulants Nonylphenols (NP) possess estrogenic activities and may cause increased risk of cancerous and reproductive abnormalities in several living organisms. Despite their harmful nature, NPs are used as additives in food packaging material, especially plastic, which is the main food contact material in today's packaging landscape. According to the fact that food packaging is one of the major potential food contaminant sources regarding NPs, there is a need for more information on identifying and quantifying of these chemicals when migrating into food. Seventeen plastic films for food packaging were analyzed for the presence of NPs; nine of them were plastic films for deep freeze food packaging. We determined and quantified NPs by Gas Chromatography-Mass Spectrometry (GC-MS) using the internal standard method. All plastic films for deep freeze food packaging contained NPs within a concentration range from 11.9 to 43.7 mg/kg. We also studied the migration of NPs from three of the plastic films for deep freeze food packaging into food simulants. The migration of NPs from these plastic films into 95% ethanol and 10% ethanol was higher than the amount migrating into distilled water or 3% acetic acid. Nonilfenole (NP) uvrščamo med motilce delovanja endokrinega hormonskega sistema. Zaradi posnemanja delovanja naravnih hormonov lahko povzročijo povečano tveganje nastanka raka in reproduktivne nepravilnosti v živih organizmih. Kljub neugodnim lastnostim, se kot dodatki uporabljajo v embalažah za živila, predvsem v plastičnih folijah. Embalaža za živila je lahko eden izmed glavnih izvorov NP v živilih. Zato so podatki o vsebnosti NP v embalaži in predvsem podatki o prehajanju NP v hrano zelo pomembni. Prisotnost NP smo preverili v sedemnajstih plastičnih folijah, ki se uporabljajo za embalažo živil. Devet izmed vzorcev je bilo plastičnih folij, ki se uporabljajo za hranjenje globoko zamrznjene hrane. Vsebnost NP smo določili s plinsko kromatografijo v povezavi z masno spektrometrijo (GC-MS) z metodo internega standarda. V vseh preiskovanih folijah, ki se uporabljajo za embalažo zamrznjene hrane smo zaznali NP v koncentracijskem območju od 11,9 mg/kg do 43,7 mg/kg folije. Z migracijskimi poskusi smo preverili prehod NP iz treh plastičnih folij v modelne raztopine. V modelni vodni raztopini z 95 % in 10 % etanola je migrirala večja količina NP kakor v samo destilirano vodo ali v modelno vodno raztopino z 3 % ocetne kisline. nonulphenols migration plastic films nonilfenol migracije embalaža za hrano true false true Angleški jezik Slovenski jezik Znanstveno delo 2012-06-01 10:27:45 2012-06-01 10:27:45 2022-04-15 13:42:01 2021-04-11 03:25:15 2011 0 0 str. 127-133 št. 1 Letn. 58 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1318-0207 66 14086149 14880790 1318-0207 URN:SI:UM:DK:YA9DBMRP Acta_Chimica_Slovenica_2011_Alfirevic_et_al._Presence_of_nonylphenols_in_plastic_films_and_their_migration_into_food_simulants.pdf Acta_Chimica_Slovenica_2011_Alfirevic_et_al._Presence_of_nonylphenols_in_plastic_films_and_their_migration_into_food_simulants.pdf 1 8FFFE6895B65D367B946534CB10A6C99 21becc70c89c043aa79f9b28a97e199791f4c5181b21c352b5306bec3e0afd43 43a9faa5-7c07-11eb-bb7a-00155d0001ca 20.500.12556/dkum/cc7b9490-526c-4194-af27-3d88a1293827 https://dk.um.si/Dokument.php?lang=slv&id=115915 http://acta-arhiv.chem-soc.si/58/58-1-127.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=115914 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
