Organoleptic Characteristics of Flavor Materials
Perfumer & Flavorist, 28, 103-103 (2003)
Determination of low phosphate concentrations in seawater by an isobutyl acetate extraction procedure.
Limnology and Oceanography, 18(3), 499-500 (1973)
American Industrial Hygiene Association journal, 51(6), 319-325 (1990-06-01)
A previously developed theoretical model was applied to investigate contaminant breakthrough on charcoal sampling tubes. Associated with the model are two important theoretical parameters. These parameters are k' (a rate constant) and tau (the time required for 50% contaminant breakthrough).
Metabolic engineering, 27, 20-28 (2014-12-03)
Medium-chain esters such as isobutyl acetate (IBAc) and isoamyl acetate (IAAc) are high-volume solvents, flavors and fragrances. In this work, we engineered synthetic metabolic pathways in Escherichia coli for the total biosynthesis of IBAc and IAAc directly from glucose. Our
Fermentation esters-formation and retention as affected by fermentation temperature.
American Journal of Enology and Viticulture, 30(4), 301-305 (1979)
International journal of food microbiology, 207, 40-48 (2015-05-24)
The aim of this work was to study ester formation and the aromatic impact of Torulaspora delbrueckii when used in association with Saccharomyces cerevisiae during the alcoholic fermentation of must. In order to evaluate the influence of the inoculation procedure
Food chemistry, 194, 196-200 (2015-10-17)
Our study focused on variations in wine aroma perception and molecular composition during tasting over a period of 30min. In parallel, dynamic analytical and sensory methods were applied to study changes in the wines' molecular and aromatic evolution. Dynamic sensory
Organoleptic threshold values of some alcohols and esters in beer.
Journal of the Institute of Brewing, 78(1), 33-36 (1972)
Molecules (Basel, Switzerland), 20(6), 10980-11016 (2015-06-18)
Developed from crosses between Vitis vinifera and North American Vitis species, interspecific hybrid grape varieties are becoming economically significant in northern areas, where they are now extensively grown for wine production. However, the varietal differences between interspecific hybrids are not
Talanta, 174, 428-435 (2017-07-26)
A vortex-assisted liquid-liquid-liquid microextraction method followed by high performance liquid chromatography-diode array detection for the determination of fourteen phenolic acids (cinnamic, m-coumaric, chlorogenic, syringic, ferulic, o-coumaric, p-coumaric, vanillic, p-hydroxybenzoic, caffeic, 2, 4-dihydroxybenzoic, sinapic, gentisic and gallic acids) in honey, iced
Drug testing and analysis, 7(3), 241-246 (2014-10-11)
South American 'crack' cocaine, produced directly from coca leaf, can be distinguished from US domestically produced crack on the basis of occluded solvent profiles. In addition, analysis of domestically produced crack indicates the solvents that were used for cocaine hydrochloride
Reproductive toxicology (Elmsford, N.Y.), 22(4), 791-796 (2006-09-19)
Occupational exposure and sniffing of toluene-based organic solvents is an important public health problem. In this study, we have investigated the effects of paint thinner inhalation on testosterone synthesis and secretion in the male rat. A control group inhaled normal
Applied microbiology and biotechnology, 87(5), 1665-1673 (2010-05-13)
We investigated the influence of the fermenter size on alcoholic fermentation. Experiments were carried out at pilot scale, in 100-L fermenters, and at laboratory scale, in stirred and static 1-L fermenters. Two musts, Grenache blanc and Sauvignon, were fermented with
Talanta, 123, 32-38 (2014-04-15)
A dynamic headspace sorptive extraction (DHS) combined with thermal desorption (TD) and coupled with gas chromatography-mass spectrometry (GC/MS) was developed for the determination of 11 esters which contribute to the fruity aroma in sweet wines. A full factorial (4 factors
Journal of chromatography. A, 1066(1-2), 225-230 (2005-03-30)
A solid-phase microextraction (SPME)-GC-MS method for three esters and the corresponding alcohols was tested for responses in accuracy, within-run precision (repeatability), and between-run precision (reproducibility) due to individual operators, individual analysis days, and differing analyte concentrations. At 5 ppm (v/v)
Electrophoresis, 11(8), 655-657 (1990-08-01)
Serum proteins of rats, exposed to methoxyethylacetate and a combination of methoxyethylacetate and isobutylacetate, were analyzed by horizontal high resolution two-dimensional gel electrophoresis with immobilized pH gradients in the first dimension. A total of 410 polypeptides were detected with either
Food chemistry, 187, 44-52 (2015-05-16)
Aroma extract dilution analysis (AEDA) is widely used for the screening of aroma-active compounds in gas chromatography-olfactometry (GC-O). In this study, three aroma dilution methods, (I) using different test sample volumes, (II) diluting samples, and (III) adjusting the GC injector
Applied microbiology and biotechnology, 99(5), 2291-2304 (2014-11-22)
Volatile compounds produced by yeast during fermentation greatly influence the organoleptic qualities of wine. We developed a model to predict the combined effects of initial nitrogen and phytosterol content and fermentation temperature on the production of volatile compounds. We used
Acta oto-laryngologica, 96(5-6), 495-500 (1983-11-01)
Industrial workers more and more frequently seek medical advice for nasal and sinus symptoms that they attribute to occupational exposure. The present study comprised 10 paint-sprayers exposed to solvents (primarily toluene and isobutylacetate) and dust. The working environment was checked
