MALDI-TOF mass spectrometry detection of extra-virgin olive oil adulteration with hazelnut oil by analysis of phospholipids using an ionic liquid as matrix and extraction solvent

Rapid screening of mixed edible oils and gutter oils by matrix-assisted laser desorption/ionization mass spectrometry

“…Different edible oils have different nutritional values and market prices [1,2]. Counterfeit and adulteration of edible oils have been frequently reported [3,4]. More public concerns about the quality and safety of edible oils have been raised with the widespread use of gutter oils in recent years.…”

Advanced detection methods for traceability of origin and authenticity of olive oils

“…Phospholipids were used as a target for detection of EVOO adulteration with hazelnut oil. 27 A specic sample extraction towards phospholipids based on the Bligh-Dyer extraction procedure using the ionic liquid of TBA (tributylamine) and CHCA (a-cyano-4-hydroxycinnamic acid) was used in the MALDI-TOF MS determination. Aer specic extraction and enrichment of phospholipids combined the MS method, a 1% contamination level of HO was found in EVOO.…”
