| 中文摘要: |
| 采用顶空-固相微萃取-气相色谱-质谱联用（HS-SPME-GC-MS）的方法分析了柠檬果肉中的挥发性风
味物质，并优化条件。对河源产尤力克、广州产里斯本、广州产尤力克柠檬进行比较，建立了采用顶空-气相色谱-质
谱（HS-GC-MS）直接测定柠檬果肉中D-柠檬烯含量的方法。结果表明，50/30 滋m DVB/CAR/PDMS 萃取头的吸附效
果最好，D-柠檬烯是柠檬果肉中挥发性风味物质的主体。广州产里斯本柠檬的挥发性风味物质种类最多，且含量较
高。测定D-柠檬烯含量时，采用25 mL 顶空瓶，50益平衡30 min，选取7 个不同的柠檬果肉质量，可得到线性良好的
标准曲线，因此采用真实果实制作标准曲线的方法是可行的。用该标准曲线对3 种柠檬中D-柠檬烯的含量进行测
定，发现广州产里斯本中D-柠檬烯含量最高。 |
| 英文摘要: |
| Headspace-solid phase micro-extraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) was
employed for analyzing volatile flavor substances (VFS) in lemon pulp, and the condition was optimized. Heyuan Eureka,
Guangzhou Eureka and Guangzhou Lisbon were compared. And D-lemonene directly determining method in lemon pulp by
HS-GC-MS was also established. The probe with 50/30 m DVB/CAR/PDMS showed the best adsorption results. Dlemonene
was the main compound in the volatile flavor substances. Guangzhou Lisbon had the most sorts of volatile flavor
substances with higher content. When we determined D-lemonene, 25 mL headspace bottle was employed with keeping
50益for 30 min and 7 levels of mass of lemon pulp were selected for establishing the standard curve, which had good
linearity. Thereby, it was possible to make standard curve by real fruits. Guangzhou Eureka had the highest D-lemonene
concentration in three different sorts of lemons by the standard curve above. |
