| description | Aim. Search of healthy and edible alternative oils from algae. Such oil provides many health benefits mainly because of docosahexaenoic acid (DHA) form of omega-3 fattyacids and some other micro nutrients in smaller amounts.
Methods. Soxhlet extraction method was used to extract the oil with n-hexane as the solvent. The proximate composition was determined by AOAC methods, while the mineral contents were determined by AAS. FTIR and UV-Visible spectra of the oil were run using Agilent- FTIR Spectrometer and UV-Visible Spectrophotometer respectively.
Results. The oil yield was very low (1.05%). The proximate composition reveals carbohydrate as the major nutrient in the residue (79.18%), others include lipid (8.03%), crude protein (5.00%), moisture (2.78%), crude fibre (3.01%) and ash (2.00%). The mineral composition reveals high amount of potassium (1602.5 mg/100g) and calcium (632.5 mg/100g) with low levels of phosphorous (14.9 mg/100g) and sodium (12.8 mg/100g). The FTIR spectrum of algae oil is similar to the normal vegetable oil. Stretching vibrations at 2922.2 cm-1 and 2855 cm-1 are attributed to methylene (-CH2--) and methyl (-CH3) groups while absorption bands at 1710 cm-1 and 1744 cm-1 showed carboxylic groups for algae oil and vegetable oil (control) which was attributed to C=O stretching vibrations (esters). The UV-Visible spectrum of algae oil showed two peaks at 408 nm and 660 nm for carotenoids and chlorophyll A respectively, which corroborate with previous studies.
Conclusions. We conclude that the oil and cake characterized from Spirogyra porticallis has great potential for medicinal and nutritional usage. |
