Phthalate esters in coffee brew samples: Analytical method by GC-MS, profile, levels and sources

The present study was aimed to develop a procedure for the analysis of trace concentration of phthalate esters (PEA) in coffee brew stored in plastic cups. Phthalates are esters of phthalic acid, generally have high boiling points, lowvolatility are insoluble in water andpredominantly fat-soluble. Phthalates with higher molecular weights, such as bis(2-ethylhexyl) phthalate (DEHP) are largely used as additives and plasticizers in plastic material (PVC), while those with lower molecular weights are components of solvents, adhesive, wax, ink, pharmaceutical products, insecticide materials and cosmetic. Dimethyl phthalate and diethyl phthalate are present in plastics based on cellulose esters …
