不同长度梗丝挥发性化学物质含量的差异性分析
|
摘要
【目的】研究成品梗丝中不同长度梗丝挥发性化学物质的差异性,为探讨梗丝结构对卷烟质量稳定性的影响提供参考。【方法】利用烟丝振动分选筛对成品梗丝进行筛分,分别测定不同长度梗丝中的挥发性有机酸和挥发性致香物质。利用单因素方差分析研究不同长度梗丝中各单项挥发性化学物质含量的差异性。利用回归分析研究不同长度梗丝挥发性有机酸和挥发性致香物质总量的变化趋势。【结果】(1)对于同一等级烟叶的烟梗制成的梗丝,不同长度梗丝各单项挥发性化学物质含量均存在显著性差异(P<0.05)和规律性变化趋势。(2)梗丝长度由大到小,挥发性有机酸总量呈线性升高趋势,挥发性致香物质及两类挥发性化学物质总量呈逐渐升高的抛物线形变化趋势。【结论】不同长度梗丝的关键挥发性化学物质含量存在较大差异,提升梗丝在烟丝中的掺配均匀性对稳定卷烟品质具有重要意义。
[Purpose]Difference of volatile chemical compounds of different length cut stem were investigated in order to provide a reference for exploring the effect of cut stem structure on the stability of cigarette quality.[Method]Cut stems were screened using cut tobacco shaker separator. The volatile chemical compound contents of different length cut stem were determined. Single factor variance analysis and regression analysis were conducted.[Results](1) There was significant difference(P<0.05) and regular variation in content of each volatile chemical compound about different length cut stems.(2) With the decrease of cut stem length, the total content of volatile organic acids increased linearity, the total content of volatile aroma compounds and two kinds of volatile chemical compounds presented an increase trend of a parabola type.[Conclusion]There were significant differences in content of volatile chemical compounds about different length cut stems. Therefore, improving the blending uniformity of cut stem had great significance for stabilizing cigarette quality.
