摘　　要：分别采用近红外光谱(NIRS)和气相色谱-质谱联用(GC-MS)法分析了3种不同类型烟用爆珠。收集了清甜型、蜜甜型和薄荷型3种类型烟用爆珠的不同批次共27个样品,采集其NIRS谱图,通过光谱数据分析结合簇类独立软模式法(Soft independent modeling of class analogy,SIMCA)对3种烟用爆珠样品建立了分类模型,采用线性判别分析法(Linear discriminant analysis,LDA)对同一类型不同批次的烟用爆珠进行质量一致性评价,同时采用GC-MS法对3种类型烟用爆珠内含物中挥发性及半挥发性成分进行了分析。结果表明,烟用爆珠香型不同,其内含物挥发性及半挥发性成分差别较大;NIRS技术可以有效判别不同颜色壁材的爆珠;建立的SIMCA模型可区分3种类型烟用爆珠,且清甜型、蜜甜型和薄荷型烟用爆珠不同批次样品的区分准确度均在90%以上,建立的LDA模型可很好地区分3种类型不同批次的烟用爆珠。Breakable capsule for cigarette filter was analyzed by near-infrared spectroscopy(NIRS)and gas chromatography-mass spectrometry(GC/MS),respectively.A total of twenty-seven different batches of three types of breakable capsules,including fresh sweet,honey sweet and peppermint,were investigated and their near-infrared spectra were collected.Classification model of three types of breakable capsule was established by the soft independent modeling of class analogy(SIMCA)with near-infrared spectra.Linear discriminant analysis(LDA)was used to evaluate the consistency of breakable capsule of the same type and different batches.Simultaneously,main volatile and semi-volatile components in the three types of breakable capsules were analyzed by GC/MS.The results showed that the main volatile and semi-volatile components of breakable capsules were different with different flavor types.NIRS could effectively identify the breakable capsule with different color wall materials.The established SIMCA model could successfully separate three types of breakable capsules,and the classifying accuracy of fresh sweet,honey sweet and peppermint breakable capsules was above 90%.At the same time,LDA models could separate different batches within each type of breakable capsule very well.NIRS was simple to operate and provided a novel,rapid,high-accuracy and nondestructive method for analysis of different types of breakable capsules.
