Abstract :

This study investigates the effect of the various process conditions such as temperature, extraction duration, particle size and solute/solvent ratio on the seed oil solvent extractions using ethanol, n-hexane and methanol/chloroform (50:50) as solvents from wild mango (Irvingia gabonensis). A 54 factorial design was employed to obtain oil yield ranged from 42.15 - 71.49%. The result showed an optimum yield of 70.78 after degumming at particle size of 400µm, temperature of 60ºC for duration of 8hrs and solute/solvent ratio of 1:5. The n-hexane gave the highest yield, followed by ethanol and lowest by methanol/chloroform blend. The physicochemical quality of the extracted oil shows that the oil could be applied in various domestic and industrial uses such as soap, biofuel, surface coating as well as candles and bio- lubricants without competing with its original food application.
