## 3 Results and Discussion
### Can Coatings Analysis via GC after a Solvent Extraction  
GC-MS was used to tentatively identify semi-volatile compounds that could potentially migrate from polymeric coatings. A GC-MS method that covered a wide mass range (from 35 to 500 \(m/z\)) with a suitable gradient of temperatures was used. Samples were injected in splitless mode. Results obtained are shown in Table 3. Only compounds with appropriate direct matching factors (SI) and reverse search matching (RSI) are identified in Table 3. In general, values of 900 or greater are considered an excellent match, 800-900 a good match, and 700-800 a fair match. For those compounds whose identification was not achievable, the most abundant \(m/z\) is specified. \begin{table}

Table 3: Compounds identified via GC-MS analysis after extraction with MeOH as a solvent. Volatile compounds coming from the beverage were detected. Thus, different esters (e.g., benzoic acid methyl ester, lauric acid methyl ester, etc.) were identified. Esters were reported by [PERSON] et al. [26] in alcoholic distilled beverages, which contribute to the greatest proportion of the total aroma. The analysis was performed using dichloromethane as an extraction solvent and the compounds were separated on a CP-Wax 52 CB (50 m \(\times\) 0.25 mm i.d., 0.2 \(\mu\)m film thickness, Chrompack). Ledene, a sesquiterpene hydrocarbon, has also been found in natural products [27]. \(\alpha\)-Methyl-8-oxo-2-phenyl-1,3-dioxolane-2-heptametitrile has been reported as a precursor of thymol and a carvacrol and eugenol intermediary [28]. Moreover, flavorings authorized in the EU [20], such as \(\alpha\)-terpineol and dodecalactone, were identified in different samples. These substances belong to Class III and Class II, according to Cramer rules, respectively. With respect to compounds coming from the packaging materials, several plasticizers, including phthalates (e.g., diethyl phthalate, butyl octyl phthalate), were identified in almost all samples. Chemicals of phthalate esters (PAEs) can act as endocrine disruptors and lead to adverse effects on organisms even in a low concentration [29]. They can also induce various etiological diseases of humans, such as disorders of the male reproductive tract, breast and testicular cancers, and dysfunction of the neuroendocrine system [30]. Isobenzofuran-1,3-dione, also called phthalate anhydride, was identified in samples BC02, BC05, BC07, and BC10. The most important derivatives of this compound
