微波无溶剂萃取蝶豆花净油及其在卷烟中的应用

Microwave solventless extraction of absolute oil from Cleitoria Ternatea L.flower and its application in cigarette

为开发新的烟用天然植物香料产品,采用微波无溶剂萃取法制备了蝶豆花净油,优化了提取工艺,运用气相色谱-质谱法(GC-MS)分析了净油中的挥发性成分,并进行了卷烟加香试验和感官评价.结果表明:微波无溶剂萃取法提取蝶豆花净油的最佳工艺是萃取时间1 h,萃取温度140℃,微波功率600 W;净油中鉴定出的主要成分有59种,主要以十五烷、十六烷、十七烷、十八烷、十九烷、二十烷、姥鲛烷等烷烃和棕榈酸乙酯、亚油酸乙酯、亚麻酸乙酯、硬脂酸乙酯等酯类为主,其他含量较高的还有植酮、2-乙酰基呋喃、吡啶、2,3,5-三甲基吡嗪等酮类和杂环类化合物,均是构成卷烟香味的重要物质;蝶豆花净油可用于卷烟加香,可以增加卷烟香气量、提升香气质、明显增加清香特征和甜感、改善舒适感、显著提升卷烟抽吸品质,具有烟用高级天然香原料的潜质.

In order to develop a new natural plant flavor product for cigarettes,the absolute oil of Cleitoria Ternatea L.flower was prepared by microwave solventless extraction and the extraction process was optimized.The volatile components in volatile oil were analyzed by GC-MS.Flavors developed were tested on cigarettes and sensory evaluation of cigarette were carried out.The results showed that the optimum conditions of microwave solventless extraction were as follows:extraction time 1 h,extraction temperature 140℃,microwave power 600 W.There are 59 main components identified in the oil.It is mainly composed of pentadecane,hexadecane,heptadecane,octadecane,octadecane,eicosane,pristane and Ethyl Palmitate,ethyl linoleate,ethyl linolenic acid ester,ethyl stearate,etc.Other high-content components such as phytonone,2-acetyl-furan,pyridine,2,3,5-trimethylpyrazine and heterocyclic compounds are important components of cigarette aroma.Cleitoria Ternatea L.flower absolute oil can be used for cigarette top flavoring,to increase the volumn and quality of cigarette aroma,give the characteristic of fragrance and sweetness,improve the smooth feeling and the quality of cigarette smoking.
