environmental and health concerns associated with the use ofhazardous solvents such as n-hexane, as well as economic considerations regarding energy consumption and waste production,have led to a resurgence of interest in mechanical pressing as a solemeans to the continuous extraction of vegetable oil. Next to this,there is a niche, high-value market for natural vegetable oils thathave not been in contact with any solvents or chemicals, particularly for the food and cosmetics industry. Twin-screw extrusionpresents an innovative technology with increasing applications inthe polymer industry, the cereal industry, the pet food industry andthe paper industry. Even though it is currently not yet applied in theoilseed processing industry, it may present a promising techniquefor sustainable vegetable oil extraction. Therefore, it has beenincreasingly applied to achieve efficient oil extraction from variousoilseeds (Dufaure et al., 1999b; Evon et al., 2013; Isobe et al., 1992;Kartika et al., 2006, 2010; Li et al., 2007; Uitterhaegen et al., 2015)and even from the whole sunflower plant (Evon et al. 2010a, 2016).This review aims to provide a clear and concise overview of recentresearch focusing on twin-screw extrusion technology as a meansfor vegetable oil extraction. Particular focus will lie on the technological advancements that have been made and the researchchallenges that are encountered during the design and optimization of novel oil extraction processes. This comprises the recoveryof vegetable oil through thermomechanical extrusion-pressing, aswell as through extrusion processes applying green solventassisted extraction techniques. It will be restricted to twin-screwextrusion, as hydraulic pressing, as well as single-screw extrusion-pressing, have been extensively described elsewhere(Lanoiselle! and Bouvier, 1994; Savoire et al., 2013).
