“…The raw moringa seed meal had fat content of 35.27±0.35 which is lower than the value (42%) reported by Ogunsina et al (2011) and higher than 30.36-35.20% observed by Anwar et al (2006) for moringa seed meal. The fat content was also higher than the values reported for other oil seeds such as melon seeds (17.36-25.06%) by Ebuchi et al (2006), and 24.8 and 30.0% for Citrillus lanatus and C. colocynth species respectively (Mabalaha et al, 2007). These variations could be attributed to the different processing methods employed or the type of oil extraction process applied (Compaore, 2011).…”

The present study aims to evaluate the effect of different processing methods on the nutrient and anti-nutrient profiles of Moringa oleifera seed before and after oil extraction. Four processing methods involving toasting at 10, 20 and 30mins, boiling at 30, 60 and 90mins, soaking at 8, 16 and 24 hours and combination of boiling (30, 60 and 90 minutes) and soaking for 72 hours were employed. The results showed that the three toasting treatments significantly increased the crude protein content while revealing a significant (p<0.05) increase in the crude protein (55.05±0.17) and ash (6.01±0.10) contents of the processed seed meal and significantly (p<0.05) lower fat (9.39±0.11), moisture (1.50±0.07) and crude fibre (3.93±0.05) contents after oil extraction. The anti-nutritional factors detected in the raw moringa seeds were (Oxalate, saponins, alkaloids, phytic acid, tannin, cyanide and phytate) with the following contents; 0.86±0.13, 1.50±0.06, 2.32±0.06, 269.84±1.62, 1.21±0.14, 0.56±0.04 and 69.82±0.86, respectively. Combination of boiling and soaking treatments (B30mins/S72hrs, B60mins/S72 hrs, B90mins/S72hrs) significantly (p<0.05) reduced the anti-nutritional factors. Processing, B60mins/S72hrs and B90mins/S72hrs were able to reduce all the anti-nutritional factors to acceptable levels with the exception of phytic acid which remained significantly (p<0.05) higher. All the toasting treatments significantly increased the crude protein content while boiling and soaking did not. However, displacement of oil after extraction greatly enhanced the crude protein level of the treated (B90mins/S72hrs) seed. It could be concluded that this processing method coupled with oil extraction could effectively improve on the crude protein content of the seed.

“…The method of AOAC, (1990) were adopted in the determination of the moisture and fat contents of the meal samples while the method described in AOAC, (1998) were adopted in the determination of crude fiber and protein contents of the meal samples [5,4]. The method of Ebuehi, et al, (2006) was adopted in the fatty acid analysis and the method described by Miller and Bender, (1955) was adopted in amino acid analysis respectively [15,33].…”

50% of world hungry people live in the third world countries with the worrisome implication among children under age five as a result of malnutrition. This situation persists because cheaper available sources of quality and quantity protein and energy low-cost foods (leaf vegetables and agricultural waste) and simple technologies are not exploited. Result of% yield and mass loss showed loss in mass in the study with Method 3 (with Tsamiya as coagulant) having the least value. The results of chemical composition showed energy content; WRE had the highest value (363.19 Kcal) and least value in KKB (309.63 Kcal). Protein content; YIE had the highest value (33g) and least value in AXT (21g) while carbohydrate content WRE and KKB had the highest value (51.6g) and least value in AXT (44.91g/100g). Result of amino acid profile showed eighteen amino acids (which were higher in quantity than their respective RDA values) of which ten were essential amino acids. The first limiting and second limiting amino acids were methionine and isoleucine respectively. The results of the blood analysis showed albumin value ranged from 3.6 -3.8 (g/dL), Hematocrit parameters (ASA, ALA and creatinine) and all showed no significant difference (p>0.05) between the diets and the control. Cholesterol values were within the normal range (<150 mg/dL). Result of food intake showed that the rats fed the control had the highest value (327 g) and least value in YIE (276g). PER of all the diet were higher than 2.7. Weight gained were between 38-44 g; EFU (34% -48%), NPR (3.2 -4.5) and TD (82% -95%) and showed no significant difference with the control diet. The result of the functional properties showed BD was highest in sample AXT (12.5) and least in sample YIE (6.61), WAC was highest in sample AXT (12.5) and least in sample YIE (6.61), OAC was highest in sample AXT (12.5) and least in sample YIE (6.61), MD was highest in sample WRE (89.65) and least in sample KKB (85.07), EC was highest in sample KKB (9.115) and least in sample WRE (3.25), FS was highest in sample AXT (28.27) and least in sample WRE (20.75) and PS was highest in sample KKB (23.96) and least in sample WRE (20.64). This study showed that the concentrates can support growth and development especially in infants.

“…Groundnut, also known as peanut (Arachis hypogea), is a leguminous food crop that belongs to the family leguminosae. It is an annual crop in the tropical and subtropical regions from which edible oil and protein rich by-products are obtained (Ebuehi et al, 2006). Groundnut oil is extracted from groundnut paste at household and semi-cottage levels using a manual or motor driven screw or hydraulic press to squeeze out the oil water emulsion.…”

“…Groundnut oil is extracted from groundnut paste at household and semi-cottage levels using a manual or motor driven screw or hydraulic press to squeeze out the oil water emulsion. The oil is boiled to remove the water and used as cooking oil, for production of margarine, shortening for pastries and bread processing, production of soaps, cosmetics, paints, lubricants, emulsion and for insecticides (Ebuehi et al, 2006). It is also useful as ointment base for fat soluble drugs.…”

Melon (Citrullus vulgaris), groundnut (Arachis hypogea) and shea butter (Vitellaria paradoxa) seeds have been established as major sources of edible oils, but scientific data is scanty on their minerals, heavy metals and anti-nutrient contents. Manually extracted vegetable oils from melon, groundnut and shea butter were analyzed in triplicates for some minerals (sodium, potassium, magnesium and calcium), heavy metals (copper, iron, lead and zinc) and anti-nutrients (tannin, saponin, oxalate and gossypol) using Buck Scientific Atomic Absorption Spectrophotometer Model 210 VGP standard procedures. Data were analyzed by ANOVA and results expressed as means and standard deviation accepted at p≤0.05. Sodium (40.50 to 41.10 mg/100g), potassium (702.00 to 704.36 mg/100g); magnesium (3.51 mg/100g) and calcium (2.56 mg/100g) were in the oils and they did not differ from one another at p≤0.05. The heavy metals in the oils were not significantly different from each other. They ranged from 0.0002 to 0.0004 mg/kg for lead (Pb); 0.00 to 0.0002 mg/kg for copper (Cu); 0.0005 to 0.0006 mg/kg for iron (Fe) and 0.0012 to 0.0015 mg/kg for zinc (Zn). Anti-nutrient, tannin from melon differed significantly from those of groundnut and shea butter oils at p≤0.05. Melon oil had the least saponin (0.05 mg/100g) and the three oils had the same oxalate content (0.33 mg/100g). Their gossypol content differed significantly from one another. Shea butter and groundnut oil had the lowest (0.44 µg/100g) and highest (1.07µg/100g) gossypol contents respectively. The evaluated heavy metals in all the tested oils were lower than the maximum permissible values by FAO/WHO. Further studies on phytates content and other heavy metals such as cadmium, arsenic and mercury are recommended before the oils are certified safe for human consumption.
