Js. Elmore et Kr. Langley, NOVEL VESSEL FOR THE MEASUREMENT OF DYNAMIC FLAVOR RELEASE IN REAL-TIME FROM LIQUID FOODS, Journal of agricultural and food chemistry, 44(11), 1996, pp. 3560-3563
A glass vessel that will measure the dynamic flavor release of aroma v
olatiles from model liquid foods in real time has been built. The samp
le is maintained at 37 degrees C and stirred at constant torque. Volat
iles released into the headspace are continuously swept by a constant
carrier gas flow into a quadrupole mass spectrometer via a jet separat
or. The mass spectrometer is operated in the chemical ionization mode,
and single ion monitoring of the major ion associated with each volat
ile allows real time detection. The apparatus was used to measure the
effect of alcohol content on the dynamic flavor release of four volati
le compounds from four different water/ethanol mixtures.
