| Resumo | |
Supercritical fluid (SFE) and pressurized liquid (PLE) extraction, two green and innovative techniques, were sequentially applied to obtain compounds from pequi almond, a by-product of a native Brazilian savanna fruit. SFE was carried out with carbon dioxide at 15-35 MPa and 40-60 degrees C. The SFE extracts were analyzed for global yield (4.23-45.09%), carotenoids (5.35-40.01 mu g/100 g dry almond (DA)), tocols (26.42-180.86 mu g/g oil), fatty acids (52.23-53.03% C18:1, 34.85-35.92% C16:0), oil thermal properties and triacylglycerols, which were mainly composed by oleic (O) and palmitic (P) acid (34.99-35.49% OOP, 31.67-31.77% POP). PLE was performed on the almond defatted by SFE (35 MPa, 40 degrees C), with 50-100% ethanol in water, 60-110 degrees C and 10 MPa. The PLE extracts exhibited global yield (8.44-34.01%), total reducing capacity (3.47-25.28 mg GAE/g DA), in which ellagic acid (4.04-6.73 mg/g DA) was identified, and antioxidant capacity by ORAC (30.91-48.47 mg TE/g DA) and FRAP (43.34-55.08 mg TE/g DA). Therefore, SFE and PLE extracts from pequi almond show significant nutritional and technological potential for its application in functional foods and other industrial products. The sequential SFE-PLE extraction is a sustainable strategy to recover a Brazilian local food by-product using clean solvents, thus meeting the principles of green chemistry and offering an alternative to local producers.
