Development of a reliable UHPLC-MS/MS method for simultaneous determination of zearalenone and zearalenone-14-glucoside in various feed products
in water as the loading solution, 50% methanol in water as the washing solvent, and 5 ml of methanol as the elution solvent yielded the optimal purification efficiencies. The established method was ...
Occurrence of (suspected) genotoxic flavoring substances in Belgian alcohol-free beers.
solvent-assisted flavor evaporation (SAFE) technique coupled to GC- MS (SIM) was developed and validated. Focus was put on authorized flavoring substances requiring specific attention due to a genotoxic concern ...
Occurrence of (suspected) genotoxic flavoring substances in Belgian alcohol-free beers
a wide range of compounds in various types of food and drinks. In order to improve the monitoring of flavoring substances, a versatile and accurate analytical method using the solvent-assisted flavor ...
Study of the possible migration risks of food contact materials for children under 3 years
and DCM-n-hexane (1:1) were the most efficient extraction solvents. Consequently, there was opted for the nonchlorinated solvents and EtOAc-n-hexane (1:1) was selected for the application to real ...
