Abstract

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.

辣木油在可持续应用中的多功能性

本研究的目的是提取、纯化和表征辣木油，为日常应用提供科学依据。采用机械压榨法(11.36%)和正己烷萃取法(35.48%)的平均出油率为23.92%。采用气相色谱法对压榨后的油进行分析，发现其饱和脂肪酸含量为21.5%，不饱和脂肪酸含量为78.5%，其中油酸为主要成分。混合原油经过脱胶、中和、洗涤、干燥四步精制。原油和成品油通过酸度指数(8.8;20.5和0.2 mgKOH g-1)，过氧化指数(3.3;5.4 meqO2 kg-1，未检测)，含水量(876.6;632.0和630.2 mg kg-1)，浊度(64.1;12.6和2.1 NTU)，比质量(909.5;907.2和907.0 kg m3)，运动粘度(43.6;39.1和41.7 mm2 s-1)，高功率发热量(39.7;40. 39.4 MJ kg-1)，热值较低(36.9;36.9;37.1 MJ kg-1)，灰分含量(0.05;分别为0.05和0.007%)。结果表明，辣木油在食品、化妆品、制药和生物柴油等工业中是一种可行的、可持续的原料。

期刊介绍： OCL-Oilseeds and fats, Crops and Lipids is a peer-reviewed full Open-Access scientific journal devoted to fats, lipids and oil- and protein-crops. OCL covers the entire sector. The research papers and reviews published address a range of topical matters in agronomy, plant biology, biochemistry, analytical chemistry, lipid chemistry, as well as transversal research themes such as nutrition, the health-quality-food safety nexus, innovation and industrial processes, the environment and sustainable development, economics and social development. A particular feature of OCL is the inclusion of special thematic sections focusing on a topical subject among the Journal''s core domains. Invited contributors to these thematic sections are chosen with care in order to ensure the expression of a genuine cross-section of interests and expertise.
