Abstract
|
|
|
|
This paper proposes an analytical method for determining amounts of polycyclic aromatic hydrocarbons (PAHs;benzo[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, dibenzo[a,h]anthracene, benzo[g,h,i]perylene) in coffees beans. Soxhlet extraction and liquid/liquid extraction were tested for the quantification of seven PAHs.Soxhlet extraction was followed by cyclohexane extraction and used a silica cartridge. Liquid/liquid extraction was followedby n-hexane extraction and utilized a florisil cartridge. The extracts were analyzed by HPLC-fluorescence detection (FLD)with a Supelcosil LC-PAH column. The PAH recoveries ranged from 78.68 to 96.28% for the liquid/liquid extraction, andfrom 67.47 to 84.60% for the Soxhlet extraction.
