DETERMINING THE AUTHENTICITY OF VANILLA EXTRACTS
Journal of Food Science, 1977ABSTRACT The total and free amino acids of authentic vanilla extracts of Madagascar, Tahiti, Comores, Mexican and Java beans were determined by GLC. Ten samples of single strength Madagascar vanilla extracts gave free amino acids with a mean value, standard deviation and coefficient of variation of 73.3 ppm, 19.88 ppm, and 27.12 ...

Supercritical carbon dioxide extraction of vanilla
The Journal of Supercritical Fluids, 1991Oleoresin 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

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

Coumarin in vanilla extracts: Its detection and significance
Economic Botany, 1987Coumarin was a component of some commercial vanilla preparations until banned in the United States by the Food and Drug Administration in 1954 because of evidence of hepatotoxicity in animals. However, in the present investigation coumarin was detected by capillary column gas chromatography/mass spectrometry in Mexican vanilla extracts commercially ...
