An overview of mechanisms for geperation of flavor compounds during sausage fermentation is shown in Figure 10.2. Despite the differences in the process technology and the fermentation microflora, it may be assumed that the generation of flavor during fermentation of dry cured ham is governed by the same principles.
Data are available from aroma extract dilution analysis showing the identification of those volatile compounds that have a significant impact on sausage flavor. The sign most important odor compounds in French, Italian, and Spanish salami are those originating from added spices, i.e., sulfur compounds (e.g., diallylsulfide) originating from garlic, and eugenol from nutmeg. Products of lipid oxidation, fatty acids, as well as fermentation volatiles such as acetic acid, diacetyl, and phenylethanol, further contribute to overall flavor. The comparison of flavor volatiles and sensory attributes of sausages of various origins reveals that a high level of fatty acids negative affects the sausage aroma.
