摘　　要：[目的]获得高出油率且原有生物活性物质最大限度保留的沙棘油,开发出新型天然烟用添加剂。[方法]以沙棘果为原料,采用CO2超临界萃取工艺,在单因素试验的基础上结合正交试验法研究萃取压力、萃取温度、萃取时间、CO2流量、分离压力等因素对出油率的影响,并对沙棘果油进行卷烟加香试验探讨。[结果]通过正交试验确定最佳工艺条件:萃取压力选择为26 MPa、萃取温度47℃、萃取时间4 h、CO2流速7 kg/h、分离压力6.0 MPa,在此工艺条件下沙棘油萃取率为5.82%。CO2超临界萃取工艺得到的沙棘油从酸价、碘价、皂化价、过氧化值等8项检测值符合国家标准,此提取工艺不会影响沙棘籽油的品质。卷烟加香试验结果表明,卷烟叶组中加入沙棘油后,能与烟香协调,提高香气质,增加香气丰富性,同时,还能减轻刺激性,去除杂气和改善余味。[结论]研究可为沙棘果油的萃取提供理论依据,并为卷烟增香保润工作提供参考。[Objective] To obtain sea buckthorn fruit oil with high yield and maximum retention of original biological active substances,develop a new type natural tobacco additive. [Method] With sea buckthorn fruit as raw material,using supercritical CO2 extraction technology,on the basis of single factor orthogonal test,effects of extraction pressure,temperature,time,CO2 flow rate,separation pressure on oil yield were studied,cigarette aroma improvement test was discussed. [Result] The best process condition is determined by orthogonal test： extraction pressure 26 MPa,extraction temperature 47 ℃,extraction time 4 h,CO2 flow rate 7 kg / h,separation pressure 6. 0 MPa,under this condition,sea buckthorn oil extraction rate was 5. 82%. The seabuckthorn oil acid value,iodine value,saponification value,peroxide value and so on eight values conform to the national standard,this extraction process does not affect the quality of sea buckthorn seed oil. Experimental results show that flavored cigarettes,tobacco leaf group after the addition of sea buckthorn oil,with the incense smoke coordination,improve aroma richness,increase the aroma,but also can reduce the irritation,eliminate noise and improve air aftertaste. [Conclusion]The study can provide theoretical basis for extraction of sea buckthom fruit oil,also provide reference for improving aroma richness.
