The oil samples used for this work were obtained from sunflower seeds. The seeds was prepared, dried, dehulled, conditioned and flaked. The oil was extracted by solvent extraction. The oil sample was investigated for their physico-chemical parameters which were specific gravity, refractive index, colour, flash, fire smoke, soft and turbidity points. There values were 0.923± 0.016, 1.475±0.002, 18.00 units,339.00±2.20 o C, 342±1.20 o C, 235.00±1.75 o C, 42.00±1.108.00±0.20, 42.00±1.10, respectively. Other were free fatty acid, acid value, saponification value, peroxide value iodine value and yield, the values were 1.40±0.007%, 3.09±0.24%,197.43±0.42mgKOH/goil,12.6±2.20Meq0 2/ kg, 131.60±0.71WIJ, 41.3±2.12% respectively. The qualitative determination of the fatty acid composition was carried out by methylation and application of Gas chromatography. The percentage yield which was 41.3% makes it a good source of oil. The free fatty acid (1.40%), peroxide (12.6meg KOH goil/), confirm that the oil can be processed into edible vegetable oil. The high level of unsaturated fatty acids (linoleic and oleic acids) and low level of saturated fatty acids(Myristic, palmitic and stearic acids) makes the oil a liquid oil. Finally, the oil, if refined and consumed, it will be a good source of essential fatty acid needed in the body.
The seed and pulp of Cola millenii were assessed with respect to their nutritional compositions and anti-nutrient factors. Also, the inhibitory activities were equally investigated. The result of the nutritional compositions of seed and pulp were in the range value; protein (4.10 to 5.76 g/100kg), crude fibre (2.22 to 2.83 g/100kg), crude fat (30.03 to 43.00 g/100kg), ash content (2.76 to 3.15 g/100kg), moisture content (6.90 to 9.80g/100g) and carbohydrate (10.46 to 13.79g/100kg). The result for mineral compositions showed that the seed and pulp contained the range value; calcium (168.73 to 394.78mg/100g), magnesium (459.47 to 610.29mg/100g), iron (446.56 to 1901.75mg/100g), zinc (310.26 to 481.53 mg/100g), manganese (100.02 to 555.32 mg/100g), sodium (140.99 to 187.15 mg/100g), potassium (356.47 to 417.72 mg/100g), and copper (7.80 to 9.90 mg/100g). The anti-nutrient factors detected in the seed and pulp was tannin, phytate and oxalate. The level of these anti nutrients were however low and might not pose any health hazard when compared to anti nutrients of 10-60mg/g in diet.The antimicrobial activities indicate that, the seed and pulp inhibits some species of bacteria. The result of the assessment implies that the seed and pulp can be used as a supplement because essential nutrients needed in the body were moderately present. Finally, the nutritional composition compares favourably with some common fruits.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
