橄榄油的脂肪伴随物及其功能特性Fat concomitants of olive oil and their functional characteristics

Abstract

橄榄油的营养成分丰富，含有大量的不饱和脂肪酸，且油酸含量高，同时富含一些独特的脂肪伴随物。为促进橄榄油的开发利用，介绍了橄榄油的分类、物理特性及脂肪酸组成，对橄榄油中的脂肪伴随物及其功能特性进行了综述。橄榄油中含角鲨烯、橄榄苦苷、羟基酪醇、α-生育酚、β-谷甾醇、环阿屯醇等功能活性成分，这些功能活性成分赋予了橄榄油的独特风味和保护皮肤、预防心脑血管疾病、促进骨骼生长发育、抗肿瘤、防辐射、预防糖尿病等保健功效。 Olive oil is rich in nutrients, including a large amount of unsaturated fatty acids, high oleic acid content, as well as some unique fat concomitants. In order to promote the development and utilization of olive oil, the classification, physical properties and fatty acid composition of olive oil were introduced, and the fat concomitants in olive oil and their functional characteristics were reviewed. Olive oil contains squalene, oleuropein, hydroxytyrosol, α-tocopherol, β-sitosterol, cycloartenol and other functional active components. These functional active components endow olive oil with unique flavor and health functional characteristics such as skin protection, prevention of cardiovascular and cerebrovascular diseases, promotion of bone growth and development, anti-tumor, radiation protection, and prevention of diabetes.
