Inhibition of bacterial quorum sensing by vanilla extract [PDF]

Letters in Applied Microbiology, 2006
The purpose of this study was to search for a novel quorum sensing inhibitor and analyse its inhibitory activity.Quorum sensing inhibition was monitored using the Tn-5 mutant, Chromobacterium violaceum CV026. Vanilla beans (Vanilla planifolia Andrews) were extracted using 75% (v/v) aqueous methanol and added to C. violaceum CV026 cultures.

DETERMINING THE AUTHENTICITY OF VANILLA EXTRACTS

Journal of Food Science, 1977
ABSTRACT 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, 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

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

The Determination of Vanillin in a Vanilla Extract: An Analytical Undergraduate Experiment

Journal of Chemical Education, 2005
Vanillin is an interesting compound, often used in educational chemistry. It can be synthesized from the plant extract eugenol and can be used for the preparation of diverse products. Less attention is paid, however, to the determination of vanillin, although it can be analyzed in a rather simple way.
