Almond oil extraction by supercritical CO 2 - ScienceDirect
Oil from crushed almond seeds was extracted with supercritical CO 2 at 350 bar and 40¡«C. Almond particles of three different mean sizes were tested. Extraction of the smaller particles was performed at two different solvent flow rates. Oil yields were obtained with asymptotic values at large extraction times that were close to the values

Supercritical fluid extraction of peach (Prunus persica) almond oil
The peach almond extraction results in an oil rich in oleic and linoleic acids, as well as in antioxidant compounds. Peach almond oil has important therapeutic properties and is nutritionally attractive due to the unsaturated fatty acid composition and high oleic acid content (55-77%) (Saadany et al., 2004, Calgaroto et al., 2005). Therefore
