Migration of plasticisers from the gaskets of lids into oily
The migration of plasticisers from PVC-gaskets on lids of glass jars is high and exceeds regulatory limits in many cases where the packed food contains much oil. Data on the migration of plasticisers from 109 samples (81 of which contained PVC gaskets) are presented.
Migration of plasticizers from PVC gaskets of lids for glass
Migration of plasticizers from PVC gaskets of lids for glass jars into oily foods: Amount of gasket material in food contact, proportion of plasticizer migrating into food and compliance testing by simulation - ScienceDirect Trends in Food Science & Technology Volume 17, Issue 3, March 2006, Pages 105-112 Review
Migration of plasticizers from the gaskets of lids into oily
The migration from the gaskets of lids into products in glass jars has a long history of non-compliances. In 1998, Hammarling et al. [ 1] showed that the migration of epoxidized soy bean oil (ESBO) from the gaskets into infant foods sometimes exceeded the tolerable daily intake (TDI) of 1 mg/kg body weight (bw) [ 2 ].
Specific migration of plasticisers coming from closure
The technological presence of plasticisers in PVC used for lid seals against glass rims with gaskets is certainly a significant food safety issue which has progressively gained relevance recently. PVC degradation with corresponding HCl generation in situ may cause further undesired formation of other derivatives.
Determination of polyadipates migrating from lid gaskets
Polyadipate plasticizers can be present in the polyvinylchloride (PVC) gaskets used to seal the lids of glass jars. As the gaskets can come into direct contact with the foodstuffs inside the jar, the potential exists for polyadipate migration into the food.
- Do plasticizers migrate from PVC gaskets to oily food jars?
- The background of usually high migration of plasticizers from PVC gaskets into oily foods packed in glass jars was investigated. On average, 17 mg gasket material containing 25–45% plasticizer was in direct food contact per centimeter circumference of the jar rim, ranging from 7 to 33 mg/cm (90 samples).
- Do PVC gaskets affect plasticizer migration?
- This suggests that migration may rather strongly depend on properties of PVC gaskets. The reduction of the amount of gasket material in food contact is likely to decrease the migration of plasticizers into the packed food without introducing a new additive or other, perhaps unknown compounds, i.e. it lends itself for an immediate improvement.
- Did plasticisers originate from migration of the gasket?
- In order to validate that the plasticisers in the food originated from migration of the gasket, the composition of the gasket was determined with a fourth method ( Biedermann-Brem et al., 2005 ).
- Does non-PVC sealing plastic affect consumer exposure to plasticisers?
- Data on the migration of plasticisers from 109 samples (81 of which contained PVC gaskets) are presented. The availability of non-PVC sealing plastic has most probably had a positive impact on the exposure of consumers to plasticisers.
- Do plasticisers migrate into food from 2022?
- The publication of the data is particularly pertinent due to EFSA’s call for data on the migration of plasticisers into food from 2022 ( EFSA, 2022 ). 2. Methods In total 109 samples of food in glass jars were taken from the Swiss market.
- How much plasticizer is in food contact?
- On average, 17 mg gasket material containing 25–45% plasticizer was in direct food contact per centimeter circumference of the jar rim, ranging from 7 to 33 mg/cm (90 samples). Photographs taken through a microscope suggest that the amount of gasket material in food contact could often be reduced.
