Abstract The simultaneous analysis of aflatoxins B1, G1, B2, G2 and ochratoxin A in beer was carried out by ultra‐performance liquid chromatography/tandem mass spectrometry (UPLC/MS/MS). Mycotoxins were extracted, purified concentrated from the sample one step using a solid‐phase extraction (SPE) cartridge that contained polymeric sorbent. Optimization different parameters, such as type SPE sorbent, amount wash solvent pH sample, out. mobile phase consisted gradient methanol + water (0.1%...
Hydroxyalkanoyloxyalkanoates (HAA) are lipidic surfactants with a number of potential applications, but more remarkably, they the biosynthetic precursors rhamnolipids (RL), which preferred biosurfactants thanks to their excellent physicochemical properties, biological activities, and environmental biodegradability. Because natural highest producer RLs is pathogenic bacterium Pseudomonas aeruginosa, important efforts have been dedicated transfer production heterologous non-pathogenic...
A method for the analysis of ochratoxin (OTA) in green and roasted coffee has been developed. OTA was extracted from with 1% NaHCO(3), extract filtered purified by solid-phase cleanup using a polymeric column that exhibits reversed-phase anion-exchange functionalities. analyzed on narrow-bore C(18) HPLC acetonitrile/water (0.1% formic acid) (40:60) as mobile phase quantified fluorescence detector. The presence confirmed single-quadruple mass spectrometry an electrospray ionization source....
