Flavour is usually the result of the presence, within
complex matrices, of many volatile and nonvolatile components
possessing diverse chemical and physicochemical
properties. Whereas the nonvolatile compounds contribute
mainly to the taste, the volatile ones influence
both taste and aroma. A vast array of compounds may
be responsible for the aroma of the food products, such
as alcohols, aldehydes, esters, dicarbonyls, short to medium-
chain free fatty acids, methyl ketones, lactones, phenolic
compounds and sulphur compounds (1,2).
