摘要: 采用正交试验和单因素试验相结合的方法对保加利亚玫瑰精油提取工艺进行了研究,得出的最佳工艺参数为:液料比4:1、蒸馏时间4h、蒸馏速度200mL/h(为每小时蒸出蒸馏器容积10%的馏出液)、装料量为蒸馏器的75%。蒸馏时间为最主要影响因素,其次是蒸馏速度,最后是液料比;玫瑰花的粉碎状况和蒸馏时馏出液是否回流对出油率无显著影响;玫瑰花的部位不同,其精油含量亦不相同,应采用全花蒸馏的方法生产精油;盐水质量分数2.5%可显著提高出油率。

Abstract: Factors influencing the yield of essential oil from the rose flowers are studied both by orthogonal and single factor’s analysis experiments. The processing technology for the production of essential oil is put forward. It has been found that the optimized technological parameters are: proportion of water to flowers 4:1; distilling time 4 h; distilling rate 10% of the volume of distilling vessel per hour;amount of flowers loaded 75% of the volume of distilling vessel;brine concentration 2.5% to which significantly increased the yield of rose oil. The order of the influencing significance of the parameters tested is: distilling time>distilling rate>ratio of flowers to water. To produce rose water, the ratio of distillate to water added is 2:1, distilling time 1 h.
