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).
The SCFA (acetic, propionic, isobutyric, butyric, isovaleric, valeric, and caproic acids) and one MCFA (medium chain fatty acid, heptanoic acid) in the intestinal content (caecum, proximal and distal colon) were analysed using a GLC method [34].
Pentaenoic and heptanoic acid (Sigma Chemical Co., Aberdeen, UK) were used as internal standards during fatty acid analysis.
