20]) and authentic compounds including acetaldehyde, trans-2-decenal, 2-methylpropanal, 2-methylbutanal, 3-methylbutanal, pentanal, hexanal, heptanal, (E), 2-heptenal, 2-methylthiazole, benzaldehyde, octanal, benzeneacetaldehyde, nonanal, decanal, (E,E), 2,4-decadienal, ethanol, 1-propanol, 2-furanmethanol, 1-hexanol, 1-octen-3-ol, fufural, tetradecanal, 1-octanol, acetone, 2-propanone, 2,3-butanedione, 2-butanone, 2-heptanone, 3-octanone, dimethyldisulfide, pyrazine, methylpyrazine, 2,3-dimethylpyrazine etc.
The beef sample showed 1-hexanol and 1-octen-3-ol and 2-furanmethanol which commonly appear in cooked beef at medium concentrations (Elmore et al.
To achieve this, the DOWANOL [TM] PnBGE and DOWANOL DPnP GE co-solvents present in the initial microemulsion were replaced with 1-butanol and 1-hexanol, which have lower boiling points, faster evaporation rates, and lower solubility in acrylic polymers.
A mixture of 1-butanol and 1-hexanol was used as a co-solvent blend, and the ratio between the two was varied across each level of surfactant to assess the effect of hydrophobicity on formation of stable microemulsions.
The alkyl esters synthesis was evaluated as function of type of solvents used (n-hexane or t-butanol), type of alcohol used (methanol, 1-butanol, 1-hexanol, 1-octanol or ethane-1,2-diol (ethylene glycol), temperature (30, 40 and 50 [degrees]C), alcohol/RO molar ratio (1:4, unless specified otherwise) and in respect to stepwise addition of alcohol (single addition or two or three consecutive additions at different times), (Bernardes et al.
Five different chain length alcohols were used: methanol, 1-butanol, 1-hexanol, 1-octanol and ethylene glycol (Fig.
The researchers used inverse gas chromatography to assess five compounds: 1-hexanol
, hexanal, (E)-2 hexenal, hexanone and hexane.
Those two molecules, 1-hexanol
and 2,3-butanedione, were quite a surprise, Ray says.
Other compounds that were not detectable in the exhaled breath by EXOM-HRGC-O but by ADA or AEDA, respectively, were ethyl lactate, diethyl succinate, 1-hexanol
, 3-methylthio 1-propanol, 2-phenylethanol, vanillin, as well as the furanone compounds 4-hydroxy-2,5-dimethyl-3(2H)-furanone, 3-hydroxy-4,5-dimethyl-2(5H)-furanone, 2-ethyl 3,5-dimethylpyrazine, 2-acetylpyridine, and 4-methoxy-2-methylphenol.
