Optimization of Microwave-assisted Extraction Technology of Moringa oleifera Seed Oil and Analysis of Its lipid Composition
摘要
Abstract
In order to optimize the microwave-assisted extraction technology and analyze the nutritional value of Moringa oleifera seed oil,the microwave-assisted extraction process and the compositions of lipids and fatty acids (determined by FT-IR,NMR and GC-MS) of Moringa oleifera seed oil were studied in this paper.The experimental results indicated that the optimal extraction process of Moringa oleifera seed oil were as follows:dichloromethane-methanol (3∶ 2,v/v) as solvent,liquid-solid ratio 7 mL·g-1,extracting time 10 min,and extracting temperature 70℃.Under the optimized conditions,the extraction yield was up to 38.43%.The predominant component of Moringa oleifera seed oil was triacylglycerol,and the main fatty acids were oleic acid (C18∶ 1n-9,75.77%),behenic acid (C22∶ 0,6.74%),palmitic acid (C16∶ 0,6.04%) and linoleic acid (C18∶ 2n-6,5.30%).Moringa oleifera seed oil was classified as a high-oleic acid oil species,which suggested that Moringa oleifera seed oil had high nutritional value and considerable potential for lipid exploitation.This research provided theoretical basis for microwave extraction,nutritional evaluation and development of Moringa oleifera seed oil.关键词
