Analysis of phthalate plasticizer migration from PVDC
The MD results showed that high interaction energy and fractional free volume in PVDC/DEHP/food simulant systems accelerated the migration of DEHP. These fundamental studies would provide significant insights into the migration of environmental contaminants.
Migration from plastic packaging into meat - ScienceDirect
Currently, the majority of tests to identify migrating packaging components to food are carried out using food simulants. These are needed because of the difficulty of analyzing the wide range of food matrices and also the actual conditions or stress during storage ( Sanches Silva et al., 2007 ).
Migration of nonylphenol and plasticizers from polyvinyl
The migration levels in hot foods or foods that were heated in a microwave oven were not so high (2.4-17%), which were almost similar levels to those after storing at 5°C for 24 hr. The estimated daily intakes from this study were 35 μg/person/day (0.70 μg/kg bw/day) of NP and 1050 μg/person/day (21 μg/kg bw/day) of DINA.
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
Plasticizer Migration: Ensuring Safety in Food Packaging
New plasticizer technologies allow formulators to achieve performance requirements while meeting best practices for food safety and migration By William Arendt, Marianne M. Conner, Emily McBride Food safety concern has extended to migration of materials from packaging, such as additives from ink, coatings and adhesives into the food. Figure 1.
- 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.
- 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 ).
- Do plasticizers migrate better than SML?
- Migration performance of conventional and new plasticizers were investigated. Distinct migration was due to different interactions between the plasticizers. Correlation between migration and tensile properties of the films was done. Most of commercial samples showed migration lower than SML established.
- 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 ).
- Does plasticizer affect the migration of additives?
- The results confirm that the presence of plasticizer in the plastics enhances swelling, and thus the migration of additives. The plasticizer content is in strong correlation with migration rate for all additives, except for PLA-Irgafos 168 samples.
