“…Taking into account the presence of interfering matrix components of coffee (Sadowska-Rociek et al 2015) PSA and SAX sorbent were chosen to test the clean-up of the extracts. Other filter agents and sorbents, such as Celite (diatomaceous earth) and florisil, used in previously published studies (Rétho and Blanchard 2005;Racamonde et al 2011), were also tested in our experiment.…”

A new simplified QuEChERS method, with the use of PSA sorbent and without the addition of magnesium sulphate, was established for the determination of 3-monochloropropane-1,2-diol (3-MCPD) in coffee and coffee substitutes. The final extracts were derivatised with phenylboronic acid and analysed by gas chromatography-mass spectrometry. The recoveries were in the ranges of 90.5-107 % for all coffee types. The calculated limit of detection was 2.5 lg kg -1 and the linearity within the range of 2-200 ng mL -1 . In real samples the highest level of 3-MCPD was detected in soluble coffee surrogates (average 135.6 lg kg -1 ), especially in those prepared from roasted spelt or barley, where they reached even up to 398.1 lg kg -1 . The contents of 3-MCPD in natural instant and ground coffee samples were much lower with the average of 16.6 and 14.1 lg kg -1 , respectively. Any impact of factors such as manufacturer or coffee origin was not observed.

“…The PAHs in food are mainly determined with use of high performance liquid chromatography with fluorescence detection or gas chromatography-mass spectrometry (Sadowska-Rociek et al 2015). The methods of liquid chromatography are more often used in food analysis due to the lower cost of equipment and lower cost of routine determination of the PAHs limited by law regulation.…”

Method Validation and Determination of Polycyclic Aromatic Hydrocarbons in Vegetable Oils by HPLC-FLD

The aim of this work was to determine the level of contamination of different groups of vegetable oils available on the Polish market with polycyclic aromatic hydrocarbons, i.e. benzo(a)pyrene and sum of benzo(a)pyrene, benz(a)anthracene, benzo(b)fluoranthene and chrysene, the content of which in foodstuffs is limited by Commission Regulation (EU) 2015/1125 of 10 July 2015. The research materials were refined rapeseed oils, sunflower oils, olive pomace oil, rapeseed oils with olive oil and unrefined soybean and coconut oils. The research methods included process of saponification of the vegetable oils, extraction of the polycyclic aromatic hydrocarbons fraction, clean-up by use a column packed with aluminum oxide and elution by petroleum ether, and then quantitative and qualitative determination of by high performance liquid chromatography with fluorescence detection method. Values of limit of detection and limit of quantification obtained during validation of the method were 0.18 and 0.25 μg/kg, respectively, and were significantly lower than the respective maximum values given in Commission Regulation (EU) 836/2011. The highest polyaromatic hydrocarbons content was found in unrefined coconut and soybean oils. The benzo(a)pyrene content and sum of benzo(a)pyrene, benz(a)anthracene, benzo(b)fluoranthene and chrysene in all the tested sample did not exceed the maximum levels given in Commission Regulation (EU) 2015/1125.

“…Additionally, coffee drinks that were brewed with PAH-contaminated green coffee beans might contain PAHs as well (Houessou et al 2008). Nevertheless, for coffee and coffee substitutes, no maximum levels of PAHs have been established by the European Union (EU) Commission (Sadowska-Rociek et al 2015).…”

The monitoring of food contaminants is of interests to both food regulatory bodies and the consumers. This literature review covers polycyclic aromatic hydrocarbons (PAHs) with regard to their background, sources of exposures, and occurrence in food and environment as well as health hazards. Furthermore, analytical methods focusing on the analysis of PAHs in tea, coffee, milk, and alcoholic samples for the last 16 years are presented. Numerous experimental methods have been developed aiming to obtain better limits of detections (LODs) and percent recoveries as well as to reduce solvent consumption and laborious work. These include information such as the selected PAHs analyzed, food matrix of PAHs, methods of extraction, cleanup procedure, LOD, limits of quantitation (LOQ), and percent recovery. For the analysis of tea, coffee, milk, and alcoholic samples, a majority of the research papers focused on the 16 US Environmental Protection Agency PAHs, while PAH4, PAH8, and methylated PAHs were also of interests. Extraction methods range from the classic Soxhlet extraction and liquid–liquid extraction to newer methods such as QuEChERS, dispersive solid-phase microextraction, and magnetic solid-phase extraction. The cleanup methods involved mainly the use of column chromatography and SPE filled with either silica or Florisil adsorbents. Gas chromatography and liquid chromatography coupled with mass spectrometry or fluorescence detectors are the main analytical instruments used. A majority of the selected combined methods used are able to achieve LODs and percent recoveries in the ranges of 0.01–5 ug/kg and 70–110%, respectively, for the analysis of tea, coffee, milk, and alcoholic samples.
