Summary: | This study had as aims the extraction, purification and characterization of moringa oil
for everyday applications with backing scientific. The average oil yield was of 23.92%,
using the techniques: mechanical pressing (11.36%) and by with hexane extraction (35.48%).
The oil extracted by pressing was analysed for gas chromatography, revealing a profile of
21.5% of saturated fatty acids and 78.5% of unsaturated fatty acids, having the oleic acid
as the major component. The mixed crude oil was refined in four steps: degumming,
neutralization, washing and drying. The crude and refined oils were characterised through
their acidity index (8.8; 20.5 and 0.2 mgKOH g-1), peroxide index (3.3; 5.4 meqO2 kg-1 and not detected), water
content (876.6; 632.0 and 630.2 mg kg-1), turbidity (64.1; 12.6 and 2.1 NTU), specific mass
(909.5; 907.2 and 907.0 kg m3), kinematic viscosity (43.6; 39.1 and 41.7
mm2
s-1), high power
calorific (39.7; 40. and 39.4 MJ kg-1) and calorific value lower (36.9; 36.9; 37.1 MJ
kg-1), and ash
content (0.05; 0.05 and 0.007%), respectively. The results show that moringa is a viable
and sustainable plant in the use of its oil as raw material for several industries,
especially in the food, cosmetic, pharmaceutical and biodiesel industry. |
