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.
Résumé
Cette étude avait comme objectif l’extraction, la purification et la caractérisation de l’huile de moringa pour des applications quotidiennes. Le rendement moyen de l’huile était de 23,92 %, en utilisant les techniques suivantes : pressage mécanique (11,36 %) et extraction à l’hexane (35,48 %). L’huile extraite par pressage a été analysée par chromatographie en phase gazeuse, révélant un profil de 21,5 % d’acides gras saturés et 78,5 % d’acides gras insaturés, l’acide oléique étant le composant principal. L’huile brute mixte (mélange des huiles extraites par pression et solvant, proportion 1:4) a été raffinée en quatre étapes : dégommage, neutralisation, lavage et de séchage. Les huiles brutes (pressage ou solvant) et l’huile raffinée ont été caractérisées par leur indice d’acidité (8,8; 20,5 et 0,2 mgKOH g-1), leur indice de peroxyde (3,3; 5,4 meqO2 kg-1 et non détectée), leur teneur en eau (876,6; 632,0 et 630,2 mg kg-1), leur turbidité (64,1; 12,6 et 2,1 NTU), leur masse spécifique (909,5; 907,2 et 907,0 kg m-3), leur viscosité cinématique (43,6; 39,1 et 41,7 mm2 s-1), leur pouvoir calorifique supérieur (39,7; 40,0 et 39,4 MJ kg-1) et inférieur (36,9; 36,9; 37,1 MJ kg-1), et leur teneur en cendres (0,05; 0,05 et 0,007 Les résultats montrent que moringa est une plante viable et durable dans l’utilisation de son huile comme matière première pour plusieurs industries, en particulier dans l’industrie alimentaire, cosmétique, pharmaceutique et le biodiesel.
