Abstract
| - Volatile compounds in Fuji apples harvested at two different maturities were measured at harvestand after 5 and 7 months of cold storage (1 °C) in four different atmospheres. When the sampleswere characterized by both chromatographic measurements of volatiles and responses of an electronicnose, the analyses showed a clear separation between fruits from different storage conditions (anormal cold atmosphere and three controlled atmospheres). During poststorage, the apples wereleft to ripen for 1, 5, and 10 days at 20 °C before analytical measurements were done involvingheadspace-gas chromatography methods and electronic nose type quartz crystal microbalances.Electronic nose responses registered by seven different sensors were used to classify the applesusing principal component analysis. It was possible to identify the samples from different storageperiods, days of shelf life, and harvest dates, but it was not possible to differentiate the fruitscorresponding to different cold storage atmospheres.
