This D. hansenii strain with aroma generation potential was further
applied to reformulated dry sausages, reduced in fat and salt, to determine
its ability to enhance the aroma (Corral et al., 2014b, 2015)
(Fig. 1). The results showed that the inoculated D. hansenii strain was
able to compensate the changes inwater activity produced by the reformulation
whilst it did not modify the hardness of reduced fat batches
nor the decrease in staphylococci growth observed in all reformulated
sausages. Moreover, different patterns of consumers were found
in terms of acceptability although the sensory characteristics were
affected (Corral et al., 2014b). In summary, D. hansenii inoculation resulted
in an improvement in consumer acceptability in terms of aroma
and taste although when both reductions were carried out together it
did not improve sausage acceptability. A deeper study of the biochemical
reasons for this increase in consumer preference was carried out by
Corral et al. (2015). This study confirmed the antioxidant effect of
D. hansenii together with an increase in lipolysis in the reformulated
sausages, which was in agreement with the reported lipolytic activity
observed for this yeast strain (Cano-García et al., 2014a)
