Perestrelo, Rosa published the artcileUntargeted fingerprinting of cider volatiles from different geographical regions by HS-SPME/GC-MS, COA of Formula: C4H10OS, the main research area is untargeted fingerprinting cider volatile headspace solid phase microextraction.
The volat. fingerprint of ciders produced in different geog. regions from Madeira Island was established using headspace solid phase microextraction combined with gas chromatog. mass spectrometry (HS-SPME/GC-MS) in order to explore the effects of geog. region on the volatile pattern ciders in addition to identify potential mol. geog. markers. A total of 107 volatile organic compounds (VOCs) belonging to different chem. families were identified from which 50 VOCs are common to all ciders analyzed. Significant differences in the relative content of VOCs from ciders of different geog. regions were observed The potential of the identified VOCs for ciders discrimination according to region was assessed through chemometric tools, such as principal components anal. (PCA) and partial least squares-discriminant anal. (PLS-DA). The PCA showed significant differences among ciders from different island geog. regions. Fifteen VOCs responsible for ciders discrimination were identified by PLS-DA. Fifteen VOCs, namely five terpenoids, four alcs., three acids and three esters, present variable importance in projection (VIP) values higher than one. Our findings provide relevant information related to volatile signature of ciders produced in Madeira Island, which may be a useful tool to cider-making process contributing to improve the quality of the final product. In addition, the geog. discrimination recognizes the unique and distinctive characteristics that will allow in the future to protect the quality and typicity of products originating in certain geog. regions.
