摘要:Carbonyl compounds from foods products obtained by fermentation confer them fragrance and aroma and even more, the identity and concentration of carbonyl compounds characterize the capacity of the raw material to be transformed. The highest carbonyl compounds are formed during specific processes of fermentation; they confer characteristic sensorial features to the aliment. It is given careful consideration to those lower carbonyl compounds which are the result of transformation or union of acetyl fragments generated in the process of fermentation; the simplest co mpounds from this category are acetaldehyde and diacetyl
