The origin of ester compounds in dry fermented sausages has been
mainly attributed to CNS together with the production of branched
aldehydes and methyl ketones (Montel et al., 1998). CNS produces
aroma compounds form branched chain amino acids generating
branched aldehydes that can be converted to ester compounds
imparting fruity notes as well as, through the beta-oxidation pathways
CNS producesmethyl ketones. However, other microorganisms, such as
lactic acid bacteria, yeast andmoulds, have been suggested as contributors
to ester compounds (Tjener and Stanhke, 2007) and, therefore,
further research on yeast ability to produce ester compounds during
dry fermented sausage manufacturing is essential to understand their
role in flavour development.
