Migration Of Harmful Substances From Oven Roasting Bags
In recent years, extensive research has been conducted on the migration of chemicals from PET containers, including oven roasting bags, into food and water. A review of 91 studies published in 2022 reported that around 150 food contact chemicals have been identified to migrate from PET bottles into consumables.
Among the chemicals found to migrate are known carcinogens such as antimony, as well as various endocrine-disrupting phthalates and bisphenol A (BPA). These substances have been shown to have adverse health effects, including potential cancer risks and disturbances to hormonal balance.
The migration of these harmful substances is influenced by multiple factors, including temperature and the fat content in the food being cooked or stored in PET plastic. Research has shown that the higher the fat content, the more plastic chemicals tend to migrate into the food. This finding emphasizes the importance of considering the composition of the food being cooked in plastic oven bags.
