Migration from plasticized films into foods. 5
A study of the migration of polymeric plasticizer from PVC film into olive oil indicated preferential migration of low molecular weight species. These oligomers which comprised 24% of the parent plasticizer contributed more than 90% of the plasticizer migration with the smallest oligomers migrating 90‐fold more readily than the bulk of the

Phthalate and novel plasticizer concentrations in food items
Background. Fast food consumption is associated with biomarkers of ortho-phthalates exposures. However, the chemical content of fast food is unknown; certain ortho-phthalates (i.e., di-n-butyl

Methods for determination of plasticizer migration
2 Test methods for plasticizer migration In general, plasticizer migration from PVC synthetic materials can proceed via three different mechanisms, namely volatilization, exudation or extraction, depending on the environment where the PVC coatings are located.
- Do plasticizers migrate into acidic foodstuffs?
- Thus, it has been demonstrated that a contact for prolonged time up to 40 °C did not promote the migration of plasticizers into acidic foodstuffs, but the migration of plasticizers to fatty foods can be high (75%–90% loss of plasticizers) and limit the use of PVC films as fatty food packaging. 1. Introduction
- Do plasticizers migrate into food simulants?
- In addition, commercial films have been evaluated as to plasticizers concentration and specific migration into food simulants. It was found that 25% of the samples comply with the specific migration limits for fatty foods contact while 50% might be used for contact with fatty foods with FRF 2–5.
- Does PVC film affect specific migration of plasticizers into aqueous acidic foods simulant?
- The samples of commercial PVC film displayed lower values of specific migration of plasticizers into aqueous acidic foods simulant than the quantification limit (LOQ) of the respective methods, even with concentration of approx. 40% in the formulation of the film ( Table 9 ).
- How much plasticizer migrates to the packed food?
- The quantity of plasticizer that migrates to the packed food depends on several factors such as the fat contents of the food, type and initial concentration of the plasticizer in the packaging material, storage time and temperature and the contact area ( Goulas, Salpea, & Kontominas, 2008 ).
- How does a PVC film plasticizer move to a food simulant?
- The diffusion of the PVC film plasticizer to food or to food simulants occurs in two steps: within the polymer – migration takes place via diffusion process, usually according to Fick's Second Law, and in food or food simulant – the transport mechanism of the migrant depends on the physical properties of this phase.
- Does Mercosur regulate the migration of phthalates from food packaging materials?
- Migration of phthalates, alkylphenols, bisphenol A and di (2-ethylhexyl) adipate from food packaging Plasticizers in Brazilian food-packaging materials acquired on the retail market Mercosur/GMC/Res. n. 32/10.
