| 中文摘要: |
| 比较了不同提油方法所得光皮树果实油的理化性质及脂肪酸组成。结果表明：不同提油方法对光皮树果实油的折光指数、相对密度及脂肪酸组成和含量影响不显著；对皂化值、酸值、过氧化值、磷脂含量有显著影响。生物酶法所提光皮树果实油经精炼后色泽浅、透明澄清，折光指数、相对密度、不饱和脂肪酸含量较高，皂化值、过氧化值、磷脂含量较低，品质优于索氏抽提法、化学溶剂浸提法、压榨法和水剂法所得油。 |
| 英文摘要: |
| The physicochemical properties and fatty acid compositions of Cornus wilsoniana fruit oil extracted by different methods were studied. The results showed that different extraction methods had no significant effect on refractive index, relative density, fatty acid composition and content of Cornus wilsoniana fruit oil, but had remarkable effects on saponification value, acid value, peroxide value and phospholipids content of Cornus wilsoniana fruit oil. The refined Cornus wilsoniana fruit oil extracted by enzymatic method had light and transparent color, higher refractive index, relative density and unsaturated fatty acids content and lower saponification value, peroxide value and phospholipids content. Therefore, the quality of Cornus wilsoniana fruit oil extracted by enzymatic method was better than that extracted by methods of Soxhlet extraction, solvent extraction, pressing and water extraction. |
