Plastic packaging materials (PPMs) play a crucial role in protecting and maintaining the quality of food. However, additives and chemical reactions during the manufacturing process can result in the production of endocrine-disrupting chemicals (EDCs), which may migrate into food and pose risks to food safety. Therefore, chemical risk assessment and regulatory control are important measures to reduce human exposure to these harmful substances.
Plastic packaging materials (PPMs) protect food from contamination, maintain quality, and ease transportation and distribution. Additives included during the manufacturing and processing of PPMs improve flexibility, durability, barrier properties, and sometimes aid the processing itself. During processing, these additives, even the monomers used to produce the plastics, can produce side products or breakdown products as a result of degradation and various chemical reactions. These starting substances and reaction products include 2,2-bis(4-hydroxyphenyl)propane (bisphenol A), phthalates/phthalic acid esters, alkylphenols, and bis(2-ethylhexyl) adipate, which are considered endocrine-disrupting chemicals (EDCs) that may interfere with the human endocrine system and produce adverse reproductive, neurological, developmental, and immune effects. When in contact with food, EDCs can migrate into food if conditions are appropriate, thereby possibly jeopardizing food safety. Chemical risk assessment and regulatory control were developed to reduce human exposure to harmful migrated EDCs. This article gives an overview of the migration of EDCs from PPMs and control measures to reduce the risk of adverse impacts on human health.
