定色后期稳温点对烟叶常规化学成分和致香物质的影响

以普洱市景东县烟区烟叶为研究对象,通过对不同部位最佳采收成熟度烟叶定色阶段后期稳温点的研究,分析了定色后期不同稳温处理与烟叶化学成分、致香物质的关系,结果表明:变黄期采用“低温慢变黄”处理,上部成熟烟叶54℃稳温16h、中部成熟烟叶稳温8h、下部适熟烟叶稳温16h的烟叶常规化学成分含量在较适宜范围,糖碱比、氮碱比较为适宜,钾氯比均大于4,接近或符合优质烟叶的特征;烟叶致香物质总量及各类中性致香物质总量明显高于其他处理,由此表明通过优化烟叶烘烤工艺能使各部位烟叶品质向有利的方向转化。...

The author studied the keeping of constant temperature at the later color -fixing stage of different parts of tobacco leaves with the best maturity collected from Jingdong county , Pu’ er city, and analyzed the relationship between the baking technolo-gies at the later color-fixing stage and the chemical compositions and aroma components of flue -cured tobacco leaves .The results showed that adopting “gradual yellowing at low temperature” baking treatment ( keeping 54℃constant temperature for 16 h for up-per leaves with complete maturity , 8 h for middle leaves with comp
