| 中文摘要: |
| 研究了精炼工艺对椰子油品质的影响。分析了毛椰油、碱炼油、脱色油、脱臭油的理化指标、脂肪酸、甘油酯组成和脂肪伴随物（甾醇、生育酚、多酚）的变化情况。结果表明：精炼工艺使椰子油的酸值、过氧化值显著降低，脂肪酸和甘油酯组成无显著变化；总甾醇、总生育酚和多酚含量显著降低，损失率分别为63.77%、68.03%、71.20%。综上表明，精炼能够显著影响油脂品质，需注重油脂适度加工技术的应用。 |
| 英文摘要: |
| The effect of refining process on the quality of coconut oil was investigated. The changes of the physicochemical indexes, fatty acid composition, glycerides composition and fat accompaniment (sterol, tocopherol and polyphenol) of crude coconut oil, deacidified oil, bleached oil and deodorized oil were analyzed. The results showed that the acid value and peroxide value of coconut oil significantly decreased in the refining process, but there was no significant change in fatty acid composition and glycerides composition. The contents of total sterol, total tocopherol and polyphenol significantly decreased, and the loss rates were 6377%, 68.03% and 71.20%, respectively. These results showed that refining process could significantly influence oil quality, which indicated the necessarity of moderate processing in oil industry. |
