Extracting endocrine disrupting compounds from infant formula using supercritical carbon dioxide

The extraction of the endocrine disrupting compounds (EDC) di-(2-ethylhexyl) phthalate (DEHP), 4-nonylphenol (4-NP) and bisphenol A (BPA) from infant formula using supercritical carbon dioxide (scCO2) was successfully achieved. These compounds are regarded as the most frequent EDCs in food. The highest extraction in a spiked sample (2 μg/g added of each compound) was 1.8 ± 0.20, 0.5 ± 0.08 and 0.6 ± 0.08 μg/g for DEHP, 4-NP and BPA,...
