The solubility curves for ethyl acetate are shown in Figures 18-20, and are representative of methyl acetate, methylbutanoate, ethyl proprionate, isopropyl acetate, butyl acetate, isoamyl acetate, ethyl-2-methylproprionate and butanoic acid. These esters were unique in that the solubility potentials for PPS and PET increase with increasing blend concentration as shown in Figure 18.
Small chain fatty acids such as propanoic and butanoic acids were produced from day 2 whereas big chain fatty acids like heptanoic and hexanoic acids were produced from day 5 in all cacao cultivars.
Trimethylamine (a fishy odor), 2-methylpropanal (a malty, dark chocolate odor), 3-methylbutanal (a malty, dark chocolate odor), acetic acid (a sour odor), propanoic acid (a cheesy odor), 2-methylpropanoic acid (a cheesy odor), butanoic acid (a cheesy odor), 3-methylbutanoic acid (cheesy, sweaty odors) and methional (a cooked potato odor) had the highest odor activity values--greater than 100.
aegypti showed potential larvicidal property which might be due to the presence of various phytochemical constituents such as propanoic acid, butanoic acid, benzene acetic acid, 4-(1,1-dimethylethyl)-methyl ester, phthalic acid, hexadecanoic acid, 1,2-benzendicarboxylic acid and 9-octadecenamide which may cause degeneration of the pupal alterations in the respiratory system of mosquito larvae, and reproductive system (28-29, 31).

For example, there are differences in the concentration of aromatic compounds, such as ethyl propanoate ('fruity'), 2-methyl butyl acetate ('banana'), hexyl acetate ('lolly') and 3-methyl butanoic acid ('cheesy').
Examples are butanoic acid and phenyl acetic acid (previously identified in palm wine samples by means of ADA as well as AEDA), acetic acid, methyl propanoic acid, pentanoic acid, and 3-methylpentanoic acid (previously identified by AEDA only).

PC1 also separated the wine from the nonextracted wine without pectase, based on alcohols (butanol and 3-methylthiopropanol), acids (isobutyric and butanoic acid), and esters (ethyl 3-hydroxybutyrate and butyrolactone).
