| dc.description.abstract | Home-Made And Industrially Produced Niger Seed Oils Were Characterized By Florescence Spectrometer In Order To Analyze The Impact Of Industrial Process On The Physical And Chemical Properties Of The Oil. Fluorescence Spectra Were Collected In The Visible Range Of Spectrum Using Cary Eclipse Luminescence Spectrometer. Excitation Wave Length Was Varied From 350nm?��?380 Nm With An Incremental Step Of 10 Nm And The Slit Width Was Kept At 5nm. Spectral Analysis Was Done Using Origin 8 Software. Experimental Results Indicated That The Major Component In Oil Samples (Home-Made, Unrefined And Refined Industrially Produced) Were Vitamin E, Poly Unsaturated Fatty Acid And Chlorophyll. The Emission Spectra Recorded In The Range Of Band Between 400 Nm - 500nm Are Related To Poly Unsaturated Fatty Acids, Emission Spectra Recorded In The Range Of Band Between 500nm-550nm With Peak Around 548nm Is Related To Vitamins E And The Band Of Emission Wave Length Between 650nm - 725nm Is Related To Chlorophyll. It Was Also Observed That Refined Oil Had Very Small Vitamin E Peak. This Could Be Associated With The Heating Process Of Refining, As Vitamin E Is Heat Unstable. Moreover, Th | en_US |
