| 本研究以6种具有代表性的柚果实为原料，采用水蒸气蒸馏法提取了可用于制备加香特种纸的柚皮精油，并对其挥发性组分、关键香气物质及热裂解行为进行了系统分析。结果表明，柚皮精油中共鉴定出52种挥发性组分，其中单萜烯类物质含量最高（22.5%~92.8%）；精油处理卷烟的感官评价显示，梁平柚皮精油的果香与甜香最突出，相对气味活度值（ROAV）分析可确定圆柚酮（ROAV=100）与D-柠檬烯（ROAV=2.175）为梁平柚皮精油的关键香气物质；丰都红柚皮精油与龙安柚皮精油因氧化柠檬烯含量较高（7.4%~11.9%）且缺乏圆柚酮，导致香气品质不佳。此外，梁平柚皮精油热解更完全（残留率11.7%），并能释放来自圆柚酮的特征风味分子碎片；丰都红柚皮精油的热解残留率达65.7%。适宜的D-柠檬烯与圆柚酮比值（26.10）是构成梁平柚皮精油风味优异的关键。 |
| Abstract: |
| In this study， essential oils of pomelo peels suitable for the production of fragranced specialty paper were extracted by steam distillation from six representative pomelo varieties， and a systematic analysis was conducted on their volatile components， key aroma compounds， and pyrolysis behavior. The results showed that 52 volatile components of the essential oils of pomelo peels were identified， with monoterpenes being the most abundant (22.5%~92.8%). The sensory evaluation of essential oil processed cigarettes indicated that fruity and sweet aromas were most prominent of essential oil of Liangping pomelo peel. The relative odor activity value (ROAV) analysis identified that nootkatone (ROAV=100) and D-limonene (ROAV=2.175) were the key aroma compounds of essential oil of Liangping pomelo peel， whereas the essential oils of Fengdu red pomelo peel and Long’an pomelo peel showed poor aroma quality due to high levels of oxidized limonene (7.4%~11.9%) and the absence of nootkatone. In addition， the pyrolysis of essential oil of Liangping pomelo peel was more complete (residue rate of 11.7%) and released characteristic flavor compounds derived from nootkatone， while the pyrolysis residue rate of essential oil of Fengdu red pomelo peel reached 65.7%. The suitable ratio of D-limonene to nootkatone (26.10) was key to the superior flavor quality of essential oil of Liangping pomelo peel. |
