A Study Based on BIS Standard IS9845:1998 for Assessing the Migration of Bisphenol A from Food Contact Plastics

Abstract Plastics are extensively utilized in the food packaging industry, where they come into direct contact with food products. During processing or storage, the influence of physical factors may cause these plastics to release chemicals into food. This study applied the testing conditions outlined in the Bureau of Indian Standards (BIS) method IS9845:1998 to evaluate the migration of bisphenol A (BPA), an endocrine-disrupting chemical, from plastic containers intended for food contact. We selected three types of polymers for analysis: polycarbonate (PC), polyethylene terephthalate (PET), and polypropylene (PP). The investigation involved the use of five different food simulants under a variety of temperature and storage duration conditions. The BPA that migrated into the simulants was extracted via solid phase extraction (SPE) and analysed using a reverse-phase high-performance liquid chromatography (HPLC) system. Data analysis and interpretation were performed using the SPSS and R software packages. The results suggest that aqueous food substances, regardless of their acidity, are more susceptible to BPA contamination when in contact with PC containers subjected to elevated temperatures and/or extended storage periods.
