These results were in agreement with the production of volatile
compounds from different yeast strains (D. hansenii) isolated from
traditional dry sausages and inoculated in a culture media containing
an alcohol and acid compound for ester production (Cano-García et al.,
2013). Although not all yeast strains showed the ability to produce volatile
compounds, seven yeasts showed a different ability to produce
ethyl and methyl esters, sulphur, alcohols, aldehydes and ketones.
Even though the production of the ester and sulphur compounds
seemed to be a strain trait, no correspondencewas foundwith theirmolecular
profiles. The confirmation of the aroma potential of these isolated yeasts was further studied in a meat model resembling dry
fermented sausage conditions (Cano-García et al., 2014a). In this
sausage model, three D. hansenii yeasts displayed a characteristic
aroma potential to produce ester and sulphur compounds in contrast
to the other isolated yeasts. But once again, the authors did not find a
correspondence between the aroma profile and the molecular patterns
of the different yeasts.
