Determination of aflatoxins in olive oil by liquid chromatography–tandem mass spectrometry

Quantification of mycotoxins in vegetable oil by UPLC-MS/MS after magnetic solid-phase extraction

“…Several analytical methods have been developed for mycotoxin determination in vegetable oils, including HPLC fluorescence (Papachristou & Markaki 2004;Bao et al 2012;Gimenez et al 2013), GC-MS/MS (Qian et al 2015) and LC-MS/ MS (Cavaliere et al 2007;Gottschalk et al 2009). Methods based on GC usually require a tedious derivatisation step.…”

Aflatoxins: Contamination, Analysis and Control

“…The ionization sources employed based on atmospheric pressure ionization techniques such as electrospray ionization (ESI) or atmospheric pressure chemical ionization (APCI) has resulted in a range of new methods (Beltrán et al, 2011;Cavaliere et al, 2007;Kokkonen & Jestoi, 2009;Sulyok et al, 2007). The advantages of LC-MS techniques lie in the improved detection limits, the confirmation provided by mass spectral fragmentation and the ability to filter out by mass any impurities that interfere in spectrophotometric detectors.…”

“…Besides, ultrasonic extraction may be an efficient, safe and reliable alternative to homogenization and MSPD extractions. MSPD technique has been employed for aflatoxins' extraction in food samples (Cavaliere et al, 2007;Rubert et al, 2010;Sebastià et al, 2010). MSPD involves the homogenization of the sample together with a suitable sorbent (usually octadecylsilica) using a pestle and mortar.…”

Food Values, Spoilage Moulds and Aflatoxin Detection in Attieke (A Cassava Fermented Product)

“…The coupling of HPLC to mass spectrometry was also used for the detection technique at the excitation wavelength of 362 nm and the emission wavelength was 425 nm. The ionization sources employed was based on atmospheric pressure [21,22]. The sample was calculated by analyzing triplicates of six samples.…”
