摘要
为了研究膜分离技术对罗汉果浸膏的精制效果和不同精制组分的差异性,采用50nm陶瓷膜,100kDa有机膜对罗汉果浸膏进行了分级分离,将罗汉果浸膏分成M1、M2、M3、M4四个组分,采用气相色谱-质谱法(GC/MS)分析了各组分的挥发性成分并进行了主成分分析,且进行了卷烟加香试验。结果表明:①感官评吸结果表明,在4个组分中,M3组分的加香效果最佳。②从4个组分中共检测出43种成分,其中,从M3组分中检出24种成分,总量为2585.41μg/g,其中的金合欢醇、顺-β-金合欢烯可赋予卷烟花香、青香和木香香韵。③主成分分析结果显示,M3组分与M1、M2、M4有显著差异,M2和M4组分的香味成分无显著差异,M3组分的主要成分有二十六烷、二十三烷、α-法尼烯、(E,E)-3,7,11-三甲基-2,6,10-十二碳三烯醛、S-(Z)-3,7,11-三甲基-1,6,10-十二烷三烯-3-醇、二十一烷、油酸酰胺等。④粒相物挥发性成分分析结果表明,M3组分可降低卷烟烟气粒相物中苯系化合物的释放量,对卷烟的安全性有积极作用。
In order to investigate the refining effect and difference of different refining components of natural flavor from Siraitia grosvenorii by membrane separation technology, a Siraitia grosvenorii extract was prepared with a 50 nm ceramic membrane and a 100 kDa organic membrane. The Siraitia grosvenorii extract was divided into four fractions, labelled as M1, M2, M3, and M4. The volatile components in each fraction were analyzed by GC-MS and followed by principal component analysis. In addition cigarette flavoring test was conducted. The results showed that: 1) Sensory evaluation indicated that M3 was the best flavoring fraction. 2) There were 43 components detected in the four fractions, in which 24 components were detected in M3 fraction with the total material amount of 2 585.41 μ g/g. Among the flavoring components, farnesol and cis-β-farnesene could provide floral, green and woody aroma to cigarette. 3) Principal component analysis suggested that M3 significantly differed from M1, M2 and M4, however there was no significant difference between the flavor components of M2 and M4. The main components in M3 were hexacosane, tricosane,α-farnesene,(E,E)-3,7, 11-trimethyl-2,6,10-dodecatrienal, S-(Z)-3,7,11-trimethyl-1,6,10-dodecatrien-3-ol, heneicosane, oleic amide, etc. 4) The volatile component analysis of particulate matters showed that M3 could also reduce the release of alkanes and benzene-based substances (regardless of the type or content) in particulate matters of cigarette smoke and might have a positive impact on reducing some toxicants.
