Sampling methods for the study of volatile profile of PDO wine vinegars. A comparison using multivariate data analysis was written by Rios-Reina, Rocio;Morales, M. Lourdes;Garcia-Gonzalez, Diego L.;Amigo, Jose M.;Callejon, Raquel M..

High-quality wine vinegars have been registered in Spain under protected designation of origin (PDO): “Vinagre de Jerez”, “Vinagre de Condado de Huelva” and “Vinagre de Montilla-Moriles”. The raw material, production and aging processes determine their quality and their aromatic composition Vinegar volatile profile is usually analyzed by gas chromatog.-mass spectrometry (GC-MS), being necessary a previous extraction step. Thus, three different sampling methods (Headspace solid phase microextraction “HS-SPME”, Headspace stir bar sorptive extraction “HSSE” and Dynamic headspace extraction “DHS”) were studied for the anal. of the volatile composition of Spanish PDO wine vinegars. Multivariate curve resolution (MCR) was used to solve chromatog. problems, improving the results obtained. Principal component anal. (PCA) showed that not all the sampling methods were equally suitable for the characterization and differentiation between PDOs and categories, being HSSE the technique that made able the best vinegar characterization. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Application In Synthesis of Ethyl 3-ethoxypropanoate).
Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Application In Synthesis of Ethyl 3-ethoxypropanoate
