Abstract

Evaluation of the shelf life of fresh vegetables is very important and there is a need for rapid non-destructive methods for the determination of freshness and spoilage during their commercial life. For this purpose an electronic nose was evaluated to determine its usefulness in measuring the shelflife of fresh cut vegetables. Volatile changes in samples of "cicorino" and shredded carrots packaged with cling films were analysed by an electronicnose equipped with 10 MOSFET and 5 MOS sensors. Microbial spoilage and colour evolution were also evaluated. A pattern recognition software program was used to evaluate the sensor signals. The response of 5 sensor signals was used to classify the degree of freshness of both vegetables. The first principal component of PCA was correlated to the microbial population in the samples and to their colour index, showing that the electronic nose is a suitable tool to study the storage life of these products.
