摘要
采用固相微萃取-气相色谱-质谱法(SPME-GC-MS)分析海南万宁地区咖啡豆和澄迈地区咖啡豆中挥发性化学组分,通过谱库检索、保留指数对化合物定性,比较两种咖啡豆之间差异。实验结果表明:万宁地区咖啡检出化合物种类91种,澄迈地区咖啡检出106种化合物,有66种相同的化合物,相同组分为75.52%。相同化合物中万宁地区咖啡占总含量的89.86%,澄迈地区咖啡占总含量的85.70%。
Chemical component of Hainan green coffee beans was analyzed with solid phase microextraction-gas chromatography- mass spectrometry, and the discrepancy between two green coffee heans was differentiated through the spectrum database re-trieval and retention index of compound characterization. The experimental results show that: the chemical composition of Warming coffee beans and Chengmai coffee beans is basically the same. The quantity of analyzed compound in Wanning area cof-fee is 91, and in Chengmai area coffee is 106, the quantity of the same compound is 66, and the percent of the same component is 75.52%. The same compounds accounted for 89.86% of the total content of Wanning area coffee, and accounted for 85.70% of the total content of Chengraai area coffee.
