The main volatiles responsible for the clustering included organic acids such as propanoic, butanoic, and heptanoic acids; alcohols such as linalool, benzeneethanol, 2,3-butanediol, cyclohexanol, 2-heptanol, 2-octanol, and 3-octen-1-ol; aldehydes and ketones such as 1-phenyl ethenone, 2-undecanone, and butanal; esters like 2-pentanol acetate, hydrocarbons such as nonacosane and 1,3 cyclohexadiene, among others (Figure 2).
There was statistically significant difference between the concentrations of alcohols after extraction, including 1-propanol, isobutyl alcohol, Isoamyl alcohol, 3-hexen-1-ol, 2,3-butanediol, alphaterpineol, phenylethyl alcohol, and 3-ethyl-1-butanol, which could be related to the higher availability of relative amino acids in pulpy juice [24].
