Fungal volatiles as indicators of food and feeds spoilage.

A review with 58 references.  Volatile sesquiterpenes can be used for taconomic classification and species identification in Penicillium, as well as to indicate mycotoxin formation in Fusarium and Aspergillus.  Developmets in sensor technology have led to the construction of  “electronic noses” (volatile compound mappers).  Exposuer of different nonspecific sensors to volatile compounds produces characteristic electrical signals.  These are collected by a computer and processed by multivariate statistical methods or in an arificial neural network. Such systems can grade cereal grain with regard to presence of moulds as efficiently as sensory panels evaluating grain odour.  Volatile compound mapping can also be used to predict levels of ergosterol and fungal colony forming units in grain.  Further developments should make it possible to detect individual fungal species as well as the degree of mycotocin contamination of food and animal feeds.
