葡萄果渣发酵烟用香料的制备及挥发性成分分析

以葡萄果渣为原料,经过生物发酵后制备烟用香料。采用同时蒸馏萃取装置收集挥发性成分并用气相色谱-质谱仪对该香料挥发性成分进行了分析和鉴定,经毛细管色谱分离出40种组分,确认了其中35种成分,并用面积归一化法测定了各种成分的峰面积,主要成分为:苯乙醇(31.84%)、油酸乙酯(8.30%)、丙二醇(6.91%)、十六酸(5.15%)、十六酸乙酯(4.20%)、2-羟基丙酸乙酯(4.06%)、9-十六碳烯酸(3.98%)、E-11-十六碳烯酸乙基酯(3.41%)、硬脂酸乙酯(2.87%)、亚油酸乙酯(2.57%)、丁内酯(1.40%)、2,3-丁二醇(1.21%)、丁二酸二乙酯(1.16%)、9-十八碳烯酸乙酯(1.13%)、琥珀酸单乙酯(0.98%)等。将该香料进行了卷烟添加实验,结果表明,该香原料能降低余味、柔和烟香,使烟气质量明显改善。

Preparation of Grape Pomace as Cigarette Flavor by Biological Fermentation and the Analysis of Volatile Composition

The perfume for cigarette flavor was obtained from grape oomace by biological fermentation.The volatile components were collectedby using the simultaneous distillation and extraction equipment(SDE).They were indentified by the capillary GC-MS method.40 peaks were isolated and 35 compounds were identified.The relative contents of the total peak area were determined by the area normalization method.The main volatile compositions were:Phenylethyl Alcohol(31.84%),Ethyl Oleate(8.30%),Propylene Glycol(6.91%),n-He...
