Extraction of oil from Moringa oleifera kernels using supercritical carbon dioxide with ethanol for pretreatment: Optimization of the extraction process

Extraction and Characterization of Oil from <i>Moringa oleifera</i> Using Supercritical CO<sub>2</sub> and Traditional Solvents

“…Figure 6 presents the content of the main fatty acids (expressed as percentage of total fatty-acids in the oil) measured by GC/MS, for solvent extraction and Sc-CO 2 and compares it with data of Nguyen et al [4]. It is observed that oleic acid, palmitic acid, and stearic acid are the main fatty acids present.…”

“…Nguyen et al [4] report yields higher of 30% for a cell of 500 cm 3 with a flow rate of CO 2 of 0.5 m 3 /h or 0.45 kg/h (7.5 g/min) working seven hours. These yields are much higher than those reported in Figure 4 of maximum 2% for 30 minutes.…”

“…Solvent extraction has been reported by Mani et al [2] using n-hexane, petroleum ether and acetone. Experimental Soxhlet extraction using n-hexane and ethanol, and also supercritical extraction with CO 2 on Moringa seeds have been reported by Nguyen et al [4]. Extraction of essential oil components using supercritical fluids has received much attention in the past years because it presents an alternative to solvent extraction or steam distillation.…”

Estudo Do Processo De Extração Do Óleo De Moringa Oleifera Lam Utilizando Ultrassom

“…Abdulkarim et al em 2005 realizou ensaios utilizando uma extração enzimática utilizando a enzima Neutrase 0.8L da Novozyme numa concentração de 2% obtendo um teor de óleo de 22,6%. Estudos mais recentes têm relatado a extração do óleo utilizando tecnologia supercrítica empregando o CO 2 obtendo um teor de óleo de 37,84 (Nguyen et al, 2011). No entanto, não há estudos na literatura que relatam a extração do óleo empregando o ultrassom, dessa maneira, o objetivo deste trabalho foi avaliar a extração do óleo da semente de Moringa utilizando o ultrassom e verificar a influência dos parâmetros tempo de extração e volume de solvente, no teor de óleo obtido e nas propriedades físico-químicas do mesmo, comparando o processo de extração utilizando prensa hidráulica.…”

Agrobacterium tumefaciens-mediated transformation of drumstick (Moringa oleifera Lam.)

“…Drumstick is considered a fast-growing and drought-tolerant tropical perennial tree with a long history of traditional medicine and culinary uses [3][4][5]. It may also become an important species for biofuel production [6,7] and has been used in a variety of industrial materials [8,9]. Despite its importance, limited breeding and selection efforts to improve drumstick have been reported, and a limited number of cultivars have been released [2].…”
