Table 4: \(Cont.\)Most of the substances identified are food flavorings authorized in EU. For example, \(\alpha\)-terpinene, benzaldehyde, 1-hexanol-2-ethyl, limonene, nonanal, carvone, ethyl-decanoate, and 2-azepanone, among others. Limonene provides a pleasant lemon scent; it is a common compound found in natural products such as resins of plants and in consumer goods such as fruit juices and juices beverages. Additionally, it is used as a raw material to manufacture cardboard or paper [37; 38]. In the case of nonanal, it has also been detected in several materials, e.g., paper, polyethylene and polypropylene. It is characterized by a strong odor.
