Sugarcane honey (SCH) is a syrup produced on Madeira Island and recognized by its unique aroma, a complex attribute of quality with an important influence on the final consumer’s acceptance of the product, and determined by a complex mixture of a large number of volatile organic compounds (VOCs) generated during its traditional making process and storage. Therefore, the purpose of this study was to establish the volatile profile of genuine SCH produced by a regional certified producer for seven years and compare it with syrups from non-certified regional producers and with producers from different geog. regions (Spain, Egypt, Brazil and Australia), as a powerful strategy to define the volat. fingerprint of SCH. Different volatile profiles were recognized for all samples, with 166 VOCs being identified belonging to different chem. classes, including furans, ketones, carboxylic acids, aldehydes and alcs. Chemometric anal. allowed (i) the differentiation between all syrups, being more pronounced between SCH and other syrups; and (ii) the identification of 32 VOCs as potential markers for the traceability and authenticity of SCH on the global market. In the experiment, the researchers used many compounds, for example, Pyridin-4-ol (cas: 626-64-2Electric Literature of C5H5NO).
Pyridin-4-ol (cas: 626-64-2) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of −48.7 × 10−6 cm3·mol−1.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ·mol−1 in the liquid phase and 140.4 kJ·mol−1 in the gas phase. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Electric Literature of C5H5NO
