| 中文摘要: |
| 研究了玉米胚芽水分含量对其油脂品质的影响。通过调整玉米胚芽中水分含量，提取其中油脂，研究玉米胚芽水分含量变化对其油脂脂肪酸组成、理化指标、主要有益微量伴随物的影响。结果表明：玉米胚芽水分含量变化对其油脂脂肪酸组成和甾醇含量基本没有影响，但随着玉米胚芽水分含量提高，其油脂酸值、过氧化值、色泽都会升高，生育酚含量下降，并且α-生育酚和γ-生育酚含量变化与玉米胚芽油色泽红值具有良好的相关性。 |
| 英文摘要: |
| The effects of moisture content of corn germ on its oil quality were studied. By adjusting the moisture content of corn germ and extracting its oil, the effects of moisture content of corn germ on fatty acid composition, physicochemical properties and microcomponent of the oil extracted from corn germ were researched. The results showed that the change of moisture content of corn germ had no effect on the fatty acid composition and the sterol content of its oil. However, with the increase of the moisture content of corn germ, the acid value, peroxide value and color of its oil increased, the tocopherol content decreased, and 慣-tocopherol and 款-tocopherol contents had good correlation with the color red value of corn germ oil. |
