玫瑰天竺葵油的超临界流体萃取学院工程技术学院专业食品科学与工程姓名刘晓旭学号 09105046Production of rose geranium oil using supercritical fluid extraction生产的玫瑰天竺葵油的超临界流体萃取AbstractThe present work aims to apply the supercritical fluid extraction (SFE) with carbon dioxideas a clean technology to extract the natural essential oil from a Portuguese-grown rose geranium (Pelargonium sp.). Geranium oil is an important ingredient in perfumery as middle note and is a natural resource with potential to be explored in Portugal, 摘要:这个工作的目的是申请把超临界流体萃取二氧化碳作为一项清洁技术来提取葡萄牙生长的天然挥发油。
天竺葵精油作为中调香油的一个重要组成成分,是一个在葡萄牙探索的潜在的自然资源,since this plant is well adapted to our climate and soil. A new SFE equipment was designed and constructed and it was used for the extraction of geranium. The obtained extracts were characterised by GC/MS and their organoleptic quality (colour and odour) was evaluated and compared with the materials obtained by the traditional techniques—hydrodistillation and organic solvent extraction.因为这种植物可以很好的适应我们的气候和土壤。
一个新的超临界流体萃取设备被设计和建造的,它被用来提取天竺葵。
得到的提取物用GC/MS和它们的感官器官(颜色和气味)评估和用传统技术,水蒸馏,有机溶剂得到的材料作比较。
The best extraction conditions were: extraction time of 15–30 min, temperature of 40 ◦C, pressure of 90–100 bar, cut fresh plant and dynamic mode. The SFE yields varied between 0.019 and 0.22%. The CO2 geranium extract had a superior organoleptic quality, with very fresh natural floral–fruity character and a pale yellow colour, most suitable for the use in perfumery。
最好的提取条件是:提取时间是15—30分钟,温度为40◦C,压力温度为90—100巴,切新鲜的植物和动态模式。
这中间变化的超临界流体萃取的产量为0.019—0.22%。
老鹳草提取物的CO2有优越的感官质量,有新鲜的天然花香,果香和淡黄色的颜色,最适合用于香水。

Effect of operating parameters3.2 操作参数的影响In this work, the influence of the operating conditions on the extraction yield, chemical composition and organoleptic quality was considered. The extraction parameters herein studied were:time of extraction, pressure, temperature, plant pre-treatment and operating mode (static/dynamic).在这个作品中,影响的操作条件对提取率、化学成分和感官的特性都考虑在内。
提取的参数在这里是:提取时间,压力,温度,植物预处理和操作模式(动态)。
To analyze the influence of parameters on the composition of the SFE extracts, four groups of key fragrant components representative of the main types of components were considered: F1—the most volatile fraction, constituted by rose oxide and isomenthone.对超临界流体萃取物的合成物的参数影响进行分析,4组关键的芳香合成物代表的主要类型被考虑在内:F1-最易挥发性馏分,由玫瑰氧化物和异薄荷酮组成。
F2—the characteristic fraction,constituted by guaia-6,9-diene and citronellyl formate (two components characteristic of geranium oil).F2-特有的馏分,由guaia-6 citronellyl,9-diene甲酸(两部分组成,天竺葵精油)的特点。
F3—the rose scented fraction, composed of citronellol and geraniol (rhodinol fraction).F3—玫瑰的芳香馏分,由香茅醇和香叶醇组成(玫瑰醇馏分)F4—the low volatility fraction, with geranyl tiglate and phenylethyl tiglate.All the fractions were compared with the essential oil composition.F4-低挥发性馏分,有香叶基和巴豆酸苯乙酯,所有的部分与精油的合成物相比较。
3.2.1. Extraction time effect3.2.1 提取时间的影响The SFE yield and composition was not significantly affected by the extraction time, as can be seen in Table 4. It is note worthy that for very long extraction time (180 min) the amount of linalool was higher, as can be seen in Table 4, which indicates that there was a degradation of geraniol intolinalool, due to the long heating and exposure to water vapour, as was explained by Guerere et al. [13].超临界流体萃取的产量和合成物不会被提取时间明显的影响,只可以在4表中看出。
它有价值的表明了非常长的提取时间(180分钟)沉香醇的数量越高,可以在表4中看出,这表明香叶醇退化成沉香醇,是因为长时间的热量和曝光成水蒸气,这被Guerere等人解释。
3.2.2. Pressure effect3.2.2 压力的影响The SFE yield was significantly influenced by the extraction pressure, as can be seen in Table 4. In fact, increasing the extraction pressure from 80 to 160 bar, the yield increased more than 10 times. The higher CO2 density at high pressures increases its solvent power and therefore more substances were extracted.抽取压力对超临界流体萃取的产量产生显著地影响,可以在表4中看出。
实际上把提取压力从80巴提高到160巴,产量就被提高多于10倍。
在高压力下提高溶解力CO2密度越高,因此越多的物质就会被提取出来。
The study of pressure effect on composition is shown in Fig.4.The most volatile fraction (F1) increased with pressure, while the rose fraction (F3) and the low volatility fraction (F4) amount decreased, more significantly for F4. Consideringthe characteristic fraction (F2), citronellyl formate followed the increasing trend shown by fraction F1, while guaia-6,9-diene did not change significantly. These results show that only for the more volatile components, the increase of the soluble amount with the increasing pressure was significant.压力对合成物的影响的研究在4图中显示。
