as a true human engineer..my duty is to help you know what you never knew and to make sure you make that mark that others find difficult in this world.with that in mind i have decided to come up with a standard real samples of final year projects from various programs in the universityto enable you come out as a graduate with the best project:here is one of such just to let you know that there are more instock,all you need is send your request and you will be attended to. sample NO 1:EXTRACTION AND CHARACTERIZATION OF MORINGA SEED OIL

ABSTRACT

The effect of time, source of seeds and different solvents on the characteristics and oil yield of Moringa oleifera seeds was investigated. The Moringa oleifera seed samples was divided into two batches tagged ‘Seeds from the North’ and ‘Seeds from the South’ were dehulled, cleaned, dried and crushed into finely coarse powder. The oil extraction was done using soxhlet extraction method using Hexane, Isopropyl alcohol and Petroleum Ether as solvent between 2-12 hours and the oil extracted characterized using standard methods. The results showed a percentage oil yield of44.94%, 36.39%, and 49.38% for seeds from the North and 34.71%, 28.43%, 37.57% for seeds from the South for Hexane, Isopropyl alcohol and Petroleum Ether respectively.

The specific gravityfor the extracted oil are 0.9, 0.91, 0.91, 0.9, 0.91,0.92 and the refractive index is 1.4599, 1.4579, 1.4555, 1.4522, 1.4556 and1.4543nDfor hexane north and south sample, isopropyl alcohol north and south and petroleum ether north and sample respectively. Saponification (mg/KOH/mol) and iodine (g/100) values are 216.76, 228.55, 260.32, 228.39, 228.22 and 201.88 and 83.754, 78.678, 91.368, 85.532, 86.023 and 85.028respectively. The acid (mg/KOH/g) and peroxide (m/mol/kg) values are 8.98, 7.58, 7.21, 7.01, 8.61 and 8.12 and 2.10, 0.60, 0.86, 0.72, 2.08 and 1.06 respectively.

It can be concluded that the oil yield is increases with increase in time, varies with geographical location and type of solvent used. Petroleum Ether had the highest amount of oil yield followed by hexane then Isopropyl alcohol.The properties evaluated indicate the long shelf life, resistance to rancidity and edibility of Moringa seed oil
