摘要

Chafiar is a typical fruit of arid and semiarid regions of South America, commonly used to produce sweet honey-like syrup called "arrope" from its pulp. During the arrope production, the chafiar almonds that contain elevated amount of oil are disposed as a residue. Thus, the aim of this study was to extract the chafiar almond oil by supercritical fluid extraction evaluating the effect of temperature (40 and 60 degrees C) and pressure (20, 30 and 40 MPa) on the extraction yield and oil composition. The best condition to recover the chafiar almond oil was 60 degrees C and 40 MPa which yielded 40 +/- 1% of oil. At this condition was possible to recover the highest amounts of monounsaturated and polyunsaturated fatty acids, 363 +/- 4 and 468 +/- 13 mg/g of oil, respectively. The physicochemical characteristics of the chafiar almond oil are in accordance with the standards for edible oils. (C) 2020 Elsevier B.V. All rights reserved.
