PROXIMATE ANALYSIS, MINERALS, AND ANTI-NUTRITIONAL FACTORS OF MORINGA OLEIFERA LEAVES
Journal Title: Annals. Food Science and Technology - Year 2016, Vol 17, Issue 1
Abstract
Moringa oleifera is a multipurpose plant which is exploited as food and for various medicinal purposes. Despite its nutritional benefits, reports on its nutritional and anti-nutritional components needs updating due to the effects of climate, processing techniques like drying, differences in soil, age of plant, and the differences in the methods of analysis. M. oleifera leaves (FHI 109897) were analysed for proximate composition, minerals and anti-nutritional factors. The nutritional components and the anti-nutritional factors were analysed according to standard methods. The results obtained for proximate analysis were crude protein (15.04±0.18%), crude fat (3.91±0.04%), crude fibre (17.27±0.02%), ash (9.85±0.02%), moisture (7.10±0.02%) and gross energy (3.52±0.01%). Mineral analysis revealed that potassium was 0.93±0.002%, calcium (0.34±0.03%), sodium (0.19±0.003%), magnesium (0.58±0.001%) and phosphorus was 0.38±0.014%. Copper was 4.93±0.03mg/kg, zinc (52.3±0.01mg/kg), iron (191.3±.0.02mg/kg) and selenium was 0.01±.001mg/kg. The anti-nutritional factors analysed were phytate (1.58±0.02%), oxalate (0.87±0.02%), saponin (0.45±0.01%), tannin (0.05±0.01%), alkaloids (1.08±0.02%), flavonoids (0.004±0.001%), cyanogenic glycoside (0.19±0.001%), phenol (0.12±0.001%), trypsin inhibitor (2.77±0.03mg/g), haemagglutinin (15.81±0.04HU/mg) and chymotrypsin inhibitor (6.32±0.04CU/mg). The study concluded that Moringa oleifera is a plant with many nutritional potentials that could be exploited for the benefit of humans and animals. The study recommends the need for more nutritional evaluation of M. oleifera leaves (FHI 109897) using current methodologies.
