Physico‐Chemical Characterization of Moringa concanensis Seeds and Seed Oil

Abstract

The present work reports the characterization and comparison of Moringa concanensis seed oil from Tharparkar (a drought hit area), Pakistan. The hexaneextracted oil content of M. concanensis seeds ranged from 37.56 to 40.06% (average 38.82%). Protein, fiber, moisture and ash contents were found to be 30.07, 6.00, 5.88 and 9.00%, respectively. The extracted oil exhibited an iodine value of 67.00; a refractive index (40°C) of 1.4648; its density (24°C) was 0.8660 mg mL -1 ; the saponification value (mg of KOH g -1 of oil) was 179.00; unsaponifiable matter 0.78%; color (1 in. cell) 1.90R + 19.00Y; and acidity (% as oleic acid) 0.34%. Tocopherols (a, c, and d) in the oil accounted for 72.11, 9.26 and 33.87 mg kg -1 , respectively. Specific extinctions at 232 and 270 nm were 3.17 and 0.65, respectively. The peroxide and p-anisidine values of the oil were found to be 1.75 and 1.84 meq kg -1 , respectively. The induction periods (Rancimat, 20 L h -1 , 120°C) of the crude oil was 10.81 h and reduced to 8.90 h after degumming. The M. concanensis oil was found to contain high levels of oleic acid (up to 68.00%) followed by palmitic, stearic, behenic, and arachidic acids up to levels of 11.04, 3.58, 3.44 and 7.09%, respectively. The results of the present analytical study, compared with those for other Moringa species and different vegetable oils, showed M. concanensis to be a potentially valuable nonconventional seed crop for high quality oil.

Actual and Potential Applications of Moringa stenopetala, Underutilized Indigenous Vegetable of Southern Ethiopia: A Review

“…M. stenopetala seeds have an average moisture content (on DM basis) of 6.1 g/100 g (Table 3). This value is comparable to the corresponding values reported (5.70 g/100 g) for Moringa oleifera seeds (Anwar and Bhanger, 2003) and M. concanensis seeds (5.88 g/100 g) (Manzoor et al, 2007).…”

Physico-chemical characteristics of seed oils extracted from different apricot (<i>Prunus armeniaca</i> L.) varieties from Pakistan

“…High oleic-linoleic oils are of much interest because of their superior stability and nutritional importance. Linoleic acid is recognized as one of the most important polyunsaturated fatty acids in human food because of its preventive effects for distinct heart vascular diseases (Nicolosi et al, 2004, Manzoor et al, 2007. It is widely accepted that dietary fat rich in unsaturated fatty acids prevents cardiovascular, inflammatory, atherosclerosis, autoimmune disorders, and diabetes (Ramadan et al, 2006).…”

Evaluation of canola seeds of different cultivars with special emphasis on the quantification of erucic acid and glucosinolates

“…The specific extinctions at 232 and 272 nm, which are important indicators of oxidative deterioration of oils (McGinely, 1991;Manzoor et al, 2007), ranged from 2.17-3.16 and 0.44-0.91, respectively (Table 3). There are no previously reported data on these canola cultivars to compare the results of peroxide value and conjugated diene and triene contents with our findings reported here.…”
