Organic acids (octanoic acid
and hexanoic acid) were extracted using Gas Chromatography Solid Phase Microextraction (GC-SPME).
The heat maps in Figure 2A, for example, visualize trajectories for different treatment concentrations of octanoic acid
. The rows in each heat map (from bottom to top) correspond to discrete snapshots of the system perturbation at successive time points (0, 1, 24, and 72 hr), and the columns in each heat map show the system state based on 10 HCI end points.
Among other compounds, octanoic acid
decreased with delayed harvest, decanal was only present in FC/T1 (2012), and benzaldehyde was only present in T2 wines both years.
Nonanoic acid and octanoic acid
were considered to be inactive.
For instance, the rosy, orangy smell of octanol contrasts sharply with the rancid, sweaty odor of octanoic acid
, although the molecules differ only in a side chain of atoms.
The compound was found to be 8-[2(cis-pent-2[prime]-enyl)-3-oxo-ciscyclopent-4-enyl] octanoic acid
. Characterization of the compound was done by TLC, GC-MS, and NMR.
