“…Furthermore, Azmir et al 37) pointed out that most of the active substances were thermally unstable, which inactivated easily at relatively high temperature of MP. The content of total phytosterols was higher than that determined by Prado et al 38) , while the squalene level was lower than the result of Alves et al 11) . These differences might be ascribed to the different cultivars, geographical regions and extract methods.…”

“…Nevertheless, this means has relatively low yields 9) . High yields can be achieved by applying supercritical fluid extraction (SFE) 11,12) , but the instrument required for this technology are relatively expensive, which is not economical. Aqueous enzymatic extraction (AEE) technology is a good alternative owing to its safety, protection for nutrients, and environmental protection.…”

In this study, the recovery of pecan nut kernel oil (PNKO) obtained by mechanical pressing (MP) was compared with that obtained by ultrasonic-assisted aqueous enzymatic extraction (UAAEE). At the same time, contents of substances with proven bioactivity, fatty acid compositions, physicochemical properties and antioxidant activities of PNKO were also assessed. Obviously, the oil yield obtained by UAAEE (71.32%) was higher than that obtained by MP (56.81%). Therefore, Plackett-Burman design (PBD), as well as Box-Behnken design (BBD), further optimized the UAAEE process, and the highest oil yield of 78.83% was acquired under the following conditions: incubation time of 2 h, the mixed enzyme (cell ulase+hemicellulase+pectinase+neutrase, w/w/w/w=1/1/1/1) concentration of 2.9%, liquid-solid ratio of 4 mL/g, pH of 4, particle size of 300 μm, ultrasonic time of 20 min, ultrasonic power of 432 W and reaction temperature of 53℃. The PNKO obtained by the two methods possessed similar fatty acid composition, but that obtained by UAAEE had comparatively low acid value and peroxide value. Moreover, rich content of total phenolics, squalene and phytosterols, as well as strong scavenging activities against DPPH and ABTS + free radicals, were also contained in the PNKO obtained by UAAEE. These results demonstrated that UAAEE was an efficient method to acquire pecan nut kernel oil with excellent quality and high recovery.

“…The application of PEF as a pretreatment to increase oil extraction from pecan nut kernels displayed higher OEY than the enzymatic pretreatment (65.2%) reported by Polmann et al (2019). Furthermore, the OEYTOTAL of PEFtreated kernels was comparable to OEY achieved in the extraction of pecan nut oil using pressurized CO2 and n-butane (65.3-70.5%) (Alves et al 2019;Scapinello et al 2017).…”

“…Phytosterols and tocopherols have also been identified as minor components of pecan nuts. As a result, pecan nut oil has been recognized as a specialty oil increasing its commercial value (Alves et al 2019;Cockerham et al 2012;Hernandez 2016).…”
