Determination of Bisphenol A in Foods Using GC/MS

摘要

An alaytical method using GC/MS was developed for bisphenol A (BPA) in foods and BPA was determined in canned foods and fresh foods such as vegetables, fruit and meat. BPA was extracted with acetone from the samples and the extract was concentrated at under 40℃ in vacuo to afford an aqueous solution, which was washed with hexane after alkalization and extracted with 50/100 diethyl ether-hexane after acidification.
