Other studies have tried to show the effect of yeast enzymatic content
on the sensory properties of dry cured products. For this purpose,
yeast extracts from D. hansenii were added to the formulation of dry
fermented sausages alone or in combination with extracts from other
microorganisms (Lactobacillus sake) (Bolumar et al., 2006). The study
showed an improvement in the sensory quality of dry fermented sausages
that was related to the slight effect of amino acid generation and
an enhanced production of VOCs derived from amino acids (branched
alcohols and acids) and microbial fermentation (ester compounds).
Additional studies performed by inoculating D. hansenii yeasts in real
dry fermented sausages (Table 4) showed the activity of the reported
enzymes, such as a high myofibrillar degradation and generation of
free amino acids in inoculated dry sausages (Durá et al., 2004a). Also,
a high lipolytic activity was confirmed by a high generation of free
fatty acids in different inoculated dry fermented sausages (Corral
et al., 2015; Patrignani et al., 2007).
