Abstract

Texturing by “Instant Controlled Pressure-Drop” (DIC) used as pretreatment technique in both solvent and pressing processes allowed getting higher yields and better kinetics with perfect preservation of quality of Camelina-sativa seed vegetal oil. Response Surface Methodology (RSM) was used and led to optimize DIC processing parameters of temperature (T) and time (t) at 158 ᵒC for 41 s. For both pressing and solvent, yields were 0.3153 and 0.4490 g oil/g db (dry basis), which were 38% and 22%, respectively higher than the yields issued from the crude Camelina seeds. In addition, the composition of vegetal oil issued from DIC-textured Camelina seeds was similar to the crude raw material oil, thus relating a good preservation of the quality.
