Consequently, the hydrolysis of macromolecules, coupled with the metabolism of the corresponding hydrolytic products during fermentation (de Reu et al., 1997; Handoyo & Morita, 2006), inevitably led to changes in the biochemical composition of food substrates. Furthermore, volatile metabolites such as fusel alcohols and carbonyl compounds that are characteristic of R. oligosporus, were also generated in-situ (Feng, Larsen, & Schnurer, 2007).
With its strong lipolytic and proteolytic activity, it is believed that R. oligosporus could be a suitable strain to modulate the aroma precursor composition in green coffee beans.
