| Abstract: |
| To explore the efficient extraction method of Moringa oleifera seed oil, Moringa oleifera seed crude oil was extracted by Soxhlet extraction method, ethanol-water method and aqueous enzyme method,respectively,and Moringa oleifera seed refined oil was prepared by degumming and deacidification process. The physicochemical indexes, chlorophyll and carotenoid contents and fatty acid composition of Moringa oleifera seed crude oil and refined oil were determined to analyze the effects of different extraction methods on the quality of Moringa oleifera seed crude oil and refined oil. The results showed that the color and transparency of the crude oil and refined oil were not significantly affected by the three extraction methods, and the ethanol-water method had some effect on the odor of the crude oil and refined oil. Among the three extraction methods, the acid value of the crude oil extracted by aqueous enzyme method, iodine value, moisture and volatile matter contents of the crude oil and refined oil extracted by aqueous enzyme method were the largest, the oxidation induction time was the longest, and the chlorophyll and carotenoid contents were the lowest. The fatty acid composition and relative content of Moringa oleifera seed oil were not significantly affected by the three extraction methods (p＞0.05). In conclusion, the quality of Moringa oleifera seed oil extracted by aqueous enzyme method is generally superior among the three extraction methods. |
