Micellar electrokinetic chromatography as a screening method for the analysis of vanilla flavourings and vanilla extracts

Journal of Chromatography A, 1996
As a general example of the potential use of micellar elektrokinetic chromatography (MEKC) in food analysis, a rapid method for the determination of vanillin and related compounds and possible synthetic additives to vanilla flavourings by MEKC is described as a screening method for quality control.

Comparative Analysis of Volatiles in Traditionally Cured Bourbon and Ugandan Vanilla Bean (Vanilla planifolia) Extracts

Journal of Agricultural and Food Chemistry, 2012
Traditionally cured vanilla beans ( Vanilla planifolia ) from Madagascar and Uganda were extracted with organic solvents, and the volatiles were separated from the nonvolatile fraction using the solvent assisted flavor evaporation (SAFE) technique. Concentrated vanilla bean extracts were analyzed using GC-MS and GC-O. Two hundred and forty-six volatile

Supercritical carbon dioxide extraction of vanilla

The Journal of Supercritical Fluids, 1991
Oleoresin was extracted from vanilla beans with 2–62 g CO2/g dried bean at 306–309 K and 10–13 MPa. Effects of extraction time (5 to 1540 h), water-soaking of beans, and cryogrinding of beans on oleoresin yield and composition were determined. Vanillin yields up to 95% were attained. Extraction rate was first-order with respect to unextracted oleoresin
