Quadro generale del corso

There are several chemical and physiological factors that can modulate taste sensation and perception. Sour is a basic taste that can be perceived as pleasant but can become highly unpleasant depending on intensity and absence of other tastes. It is important to understand the distinction between the concepts of ‘acidity’ and ‘sourness’ (or perceived acidity). Bitter can be considered the most complex taste quality, based on both the wide variety of bitter tastants and on the large number of genes encoding bitter receptors. The course will discuss, based on scientific evidence, the presence of sour- and bitter-tasting compounds in coffee as well as individual variability in sour and bitter perception.
