摘　　要：为了开发利用工业化生产中磨皮取油后的剩余橙皮,提高橙皮精油得率,以伏令夏橙为研究对象,采用水蒸气蒸馏法分别提取机器磨皮所得油水混合物及磨皮后剩余橙皮的精油,计算两者精油得率并比较成分差异,从橘红和橘白中提取的挥发油作为对照。结果显示,剩余的橙皮回收利用可使橙皮精油得率提高11.55%。GC—MS分析发现油水混合物和剩余橙皮提取的精油成分有较大不同。与油水混合物提取的精油相比,剩余皮精油中的酮类化合物、酯类化合物、醇类化合物和脂肪酸相对含量较高,而烃及其衍生物的相对含量较低。试验表明回收利用磨皮后的剩余橙皮可以提高橙皮精油产量,并具有浓郁的香气。To study on utilization of residual orange peel in industrial production and increase of essential oil yield from orange peel,essential oil from yellow juice and residual orange peel were extracted inCitrus sinensis var.Valencia using steam distillation after grinding peel.Then the yield of essential oil extracted from yellow juice and residual orange peel was measured and their compounds were compared,andessential oilextracted from tangerine peel and tangerine endocarp were used as control.The results shows that the essential oil yield from orange peel can be increased（11.55%）by recycling residual orange peel,and the compounds of essential oil were different from yellow juice and residual orange peel.Compared with essential oil extracted from oil-water mixture,relative content ofketonecompound,esterscompound,alcoholcompound andaliphatic acid in essential oil extracted from residual orange peel are higher,and relative content ofhydrocarbons and their derivatives are lower.The research shows that by recycling residual orange peel can improve the yield of essential oil,and the odor of essential oil is pleasant.
