PHYSICOCHEMICAL PROPERTIES OF MORINGA OLEIFERA LAM. SEED OIL OF THE INDIGENOUS‐CULTIVAR OF BANGLADESH

Abstract

Moringa oleifera Lam. seed oil of the indigenous-cultivar of Bangladesh was extracted using n-hexane (H), light petroleum ether (LPE) (bp 40-60C) and chloroform/methanol (50:50, v/v) mixture (CM). The oil content ranged from 37.50 (H) to 40.20% (CM). The moisture, protein, ash and crude fiber contents of seed residues, and the density, refractive index, color, acidity, saponification value, iodine value, unsaponifiable matter content, oxidative state, sterols, tocopherols and fatty acid composition of the extracted oil were determined. The oil contained a high amount of oleic acid (C 18:1 ) of up to 74.41% and a high ratio of monounsaturated to saturated fatty acids with moderate oxidative stability. The results of the present study were compared with those reported in literature for different regional habitats and species variants. PRACTICAL APPLICATIONSA high-oleic oil with a good potential for edible and industrial use can be produced from Moringa oleifera Lam. (M. oleifera) oilseeds of the indigenous cultivar of Bangladesh. Thus, mature seeds of M. oleifera can be considered as an alternative source of vegetable oil in Bangladesh provided that it is cultivated on a large scale.3 Corresponding

Effect of extraction methods on physicochemical, nutritional, antinutritional, antioxidant and antimicrobial activity of Moringa (Moringa oleifera Lam.) seed kernel oil

“…This might be due to higher temperature of 85 o C applied in soxhlet extraction that lowered the specific gravity thereby the color of the oil. These values are in agreement with the earlier findings of Rahman et al (2012); Orhevba et al (2013). The color intensity of the vegetable oils depends mainly on the presence of pigments such as chlorophyll, which is effectively removed during the degumming, refining and bleaching process.…”

Evaluating coagulant activity of locally available <i>Syzygium cumini</i>, <i>Artocarpus heterophyllus</i> and <i>Moringa oleifera</i> for treatment of community drinking water, Uganda

“…Results for protein, ash, dry matter and fibre revealed characteristics similar to those reported by other authors (Akinmutimi, 2006;Kalibbala 2007;Ndyomugyenyi, 2008;Pritchard et al, 2009;Rahman et al, 2009;Sodamade et al, 2013;Olagbemide and Alikwe, 2014). The study of coagulant activity on Moringa (Moringa oleifera), Java plum (Syzygium cumini) and Jackfruit (Artocarpus heterophyllus) revealed promising level of turbidity removal from dirty water that is comparable to previous studies on Moringa and other plant seeds (Kalibbala 2007;Amagloh and Benang, 2009;Preston et al, 2010;Ali et al, 2010;Wilson and Andrews, 2011;Nand et al, 2012;Sanchez-Martin et al, 2012;Kabore et al, 2015).…”

The versatility of the Moringa oleifera oil in sustainable applications

“…It is important to highlight that the presence of small quantities of residual solvent can influence in the lowest viscosity result when compared to the one of pressing and also by the fact that the solvent removes soluble components in it (Pereira, 2015). Tsaknis et al, (1999), Lalas and Tsaknis (2002) and Rahman et al, (2009), using the extraction oil by hexane of the moringa seeds, obtained results varying from 45 to 57 mm 2 s −1 (at 40 • C), within the vegetable oil's expectations according to Singh and Singh (2010), which found 27.2 mm 2 /s for the linseed oil and 53.6 mm 2 s −1 for the crambe oil, including 32.6 mm 2 s −1 for the soybean oil, all measured at 38…”
