The determination of authenticity is an increasingly important issue for food quality and safety. The use of an electronic nose based on ultra-fast gas chromatography technique ensures rapid analysis of the volatile compounds from food products. Due to the fact that this technique enables chemical profiling of agricultural products, it can be an effective tool for authentication when combined with chemometrics. In this article presented is a methodology for classifying NFC (Not From Concentrate) juices. Samples tested were: pure orange juice, pure apple juice, as well as mixtures of these juices with known percentage of base juices. Classification of juice samples was carried out using chemometric method - Principal Component Analysis (PCA). The ultra-fast GC technique coupled with chemometrics allowed to distinguish juice samples containing only 0.5% of impurities. Developed methology is a promising analytical method for the ensurance of quality and authenticity of juices.
