Abstract

Coriander (Coriandrum sativum L.) is an annual crop belonging to the Apiaceae family and is commonly used as a condiment or a spice in the Mediterranean area. The seeds are characterized by their potential to provide both an essential and a vegetable oil. While the former fraction is traditionally obtained through hydrodistillation, the latter may be extracted by twin-screw extrusion. This further renders a press cake which could be valorized through its transformation into agromaterials. The main objectives of this study were to determine the chemical composition of hydrodistilled essential oil from coriander seeds cultivated in France and to evaluate VOC emission rates from two types of agromaterials generated from delipidated or non-delipidated coriander cake. The main components of the essential oil were linalool, g-terpinene, camphor and limonene. Enantiomeric distribution of linalool showed an enantiomeric excess of (S)-linalool (75.2%). VOC emissions of agromaterials were mainly due to the presence of essential oil in the press cake. Linalool was the most abundant compound with an emission rate of about 140 μg/m² h for the non-delipidated material. This value was lower than 2 μg/m² h for the delipidated material. Next to this, a substantial emission of the solvent used for lipid extraction was detected.
