“…AEP-SE derived oil exhibited higher antioxidant activity, which can be explained by its lower level of free fatty acid content and higher active compound content. These results are consistent with the data reported for aqueous system-extraction of sesame oil (Long et al, 2011;Ismail et al, 2010).…”

Aqueous extraction is a promising green alternative to hexane extraction. This study used a salt effect-aided aqueous extraction process (AEP-SE) for extracting Camellia oleifera seed oil (COSO) to improve oil extractability and avoid emulsification in the aqueous system. The highest oil extractability rate of 88.8% was obtained under 1.48 mol L^–1 sodium carbonate, a solution-to-flour ratio of 3.85, and 3.23h of extraction time with the quality of the aqueous system-extracted oil being similar to those of a commercial sample of COSO and hexane-extracted oil in terms of color, iodine value and saponifcation value, although its moisture content was higher. Furthermore, the free fatty acid content of the aqueous system-extracted oil was lower than that of the solvent-extracted oil. The values of the inibihitory concentration at 50% of oil obtained by AEP-SE and organic solvent extraction as measured by DPPH scavenging activity essay, were 2.27 mg/mL and 3.31 mg/mL. AEP-SE is therefore a promising environmentally friendly method for the large-scale preparation of COSO.

La extracción acuosa es una alternativa verde muy prometedora a la extracción con hexano. En este estudio se utilizó como ayuda en el proceso de extracción acuosa (AEP-SE) el efecto de una sal para la extracción de aceite de semilla de Camellia oleifera (COSO) para mejorar la extractabilidad y evitar la formación de emulsiones en el sistema acuoso. La mayor velocidad de extracción de aceite, 88,8%, se obtuvo con una concentración de carbonato de sodio de 1,48 mol L^–1, una relación de solución a la harina de 3,85, y 3.23h de tiempo de extracción, con una calidad del aceite extraído con el sistema acuoso similares a los de una muestra comercial de COSO extraida con hexano, en términos de índice de yodo, de color, y de índice de saponificación, aunque su contenido en humedad fue mayor. Además, el contenido de acidez libre del aceite extraido con el sistema acuoso fué menor que la del aceite extraído con disolvente. Los valores de la concentración inibihitoria al 50% del aceite obtenido por el AEP-SE y extracción con disolvente orgánico, medido por el ensayo de DPPH actividad de barrido, fueron 2,27 mg mL_–1 y 3,31 mg mL_–1. Por lo tanto, AEP-SE es un método favorable al medio ambiente, prometedor para la preparación a gran escala de COSO

Response surface methodology (RSM) was used to optimize ultrasound-assisted aqueous enzymatic extraction (UAAEE) conditions for perilla seed oil. Under the optimum conditions-which were a liquid-to-solid ratio of 4.4:1, a hydrolysis time of 2.66 h, a hydrolysis temperature of 50.87 °C and an ultrasound treatment time of 24.74 min-an oil yield of 31.34% was obtained. Comparisons of the physicochemical characteristics of oil obtained using UAAEE with those of oil obtained by solvent extraction (SE oil) and cold pressing extraction (CPE oil) revealed similar refractive indices and saponification values, but UAAEE oil had a higher iodine value and better stability against oxidation, with a low peroxide value. UAAEE oil contained higher levels of beneficial α-linolenic acid and phenolics than SE oil or CPE oil, and it also had superior efficiency in scavenging 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals.Keywords: perilla seed oil; ultrasound-assisted aqueous enzymatic extraction; physical and chemical characteristics; fatty acid composition; antioxidant activities.Practical Application: Based on its physical and chemical properties, perilla oil obtained using UAAEE would be suitable as high quality edible oil and could also have applications in the cosmetic and pharmaceutical industries.
