Characterization of the Key Odorants in Light Aroma Type Chinese Liquor by Gas Chromatography" Olfactometry
, Quantitative Measurements, Aroma Recombination, and Omission Studies.
The headspace vial was then sampled for GC separation with MS and olfactometry
The dynamic olfactometry
is a method where a panel of human assessors evaluates the concentration of odour in a series of standardized presentations of a gas sample.
Care must be taken to prevent odor fatigue of the human olfactometry
system, which is when a person no longer detects an odor after an intense odor experience or a long period of exposure to odorous air.
Thus, in dynamic-dilution olfactometry
there is a mixture of air flows, as opposed to air volumes.
was performed using the Sniffin' Sticks test set.
An effective approach to identifying compounds that cause odor quality defects combines conventional gas chromatograph and mass spectroscopy (GC-MS) methods with olfactometry
and multidimensional GC separation techniques.
A more accepted method for odor assessment is olfactometry
, which has been established as American Standards of Testing and Measurements (ASTM) methods E1432-91 and E679-91 (ASTM 1997a, 1997b, respectively).
The objectives of this study were to characterize volatile compounds and to determine aroma impact compounds in various fish sauces using gas chromatography coupled with an ion trap mass selective detector (GC-MSD) and a solid phase microextraction-OSME-gas chromatography olfactometry
(SPME-OSME-GCO) technique that was coupled with dilution methods.
Perfumes, polymers, processed foods, and manure - an unusual montage to say the least, unless you are an olfactometry
Chapters in part one look at the principles of sensory evaluation and how these can be applied to alcoholic beverages, covering topics such as shelf life evaluation and gas chromatography - olfactometry
Coverage progresses from an overview of flavor and fragrance materials to sample preparation, analysis of raw materials and finished products, gas chromatography and olfactometry
, multivariate techniques, and electronic nose technology and applications.
