Emissions of small straight-chain aldehydes, such as hexanal, pentanal, heptanal, octanal, and nonanal, generally exceeded emissions of other compounds and accounted for more than 50 percent of total VOC emissions.
Authentic standards of linalool, (E)-linalool oxide A (furanoid), (Z)-linalool oxide B (furanoid), (E)-linalool oxide C (pyranoid), geraniol, citral, [beta]-myrcene, D-limonene, [beta]-ocimene, nerol, nerolidol, [beta]-ionone, geranyl acetone, naphthalene, (Z)-3-hexen-1-ol, eugenol, nonanal, benzyl alcohol, benzene acetaldehyde, methyl salicylate, (Z)-3-hexenol acetate, 3-octen-1-ol, indole, and ethyl decanoate were purchased from Sigma-Aldrich (Shanghai, China).
Moreover, some aliphatic aldehydes, especially some short-chain aliphatic aldehydes ([C.sub.5]-[C.sub.9]), were also reported in sheep meat; these aldehydes are as follows: hexanal (fruity, fatty, and green), heptanal (nutty, oily, and fruity), octanal (fruity, floral, and fatty), nonanal (oily, fatty), and 2-octenal (fruity) [17].
They also verified that the volatile compounds linalool and nonanal, both reported in our samples, have been characterized as aroma-active compounds, which may contribute to floral or fruity odors in green tea infusions.
Summary: Fact.MR has announced the addition of the "Nonanal Market ": Global Industry Analysis and Opportunity Assessment "2018 to 2028" report to their offering.
The minor compounds, accounting for 0.01% to 8.5% of the total volatile compounds, included propanal, butanal, 3-methyl butanal, pentanal, heptanal, benzaldehyde, octanal, nonanal, butane, carbon disulfide, 2-butene, n-pentane, hexane, heptane, octane, ethylacetate, 2-butanone, 2,3-butanedione, 3-hydroxy-2-butanone, 2-heptanone, 2,3-octanedione, dimethyl sulfide, ethanol, isopropyl alcohol, 1-pentanol, and 1,3,5-cycloheptatriene.
200 [micro]g/[m.sup.3]) and nonanal (<50 [micro]g/[m.sup.3]) as other aldehydes identified in this gaseous fraction.
To date, nonanal has been mainly produced from a petrochemical (Octene).
The important compounds affecting the flavor of fermented jerky included DL-Glutamic Acid, Phenylethyl Alcohol, 1-Octen-3-ol, Nonanal, Pentanal, 3-Methyl-Butanal, and 2-Pentyl-Furan.
The researchers precisely determined the nature and concentrations of these compounds, and found heptanal, octanal and nonanal, which are known as aldehydes in chemistry, to be emitted at higher levels by children with malaria.
