装烟密度对抚州烤后烟叶品质的影响

Effect of Loading Density on the Quality of Flue-cured Tobacco Leaves in Fuzhou

为探究密集烘烤在江西省抚州市烟区较为适宜的装烟密度,以当地主栽品种云烟87的中部叶为试验材料,比较50、55、60、65 kg/m^(3)4种装烟密度下的烤后烟叶外观质量、物理特性、常规化学成分、中性致香物质、感官质量等指标。结果表明,装烟密度对烤后烟叶品质影响较大;在60 kg/m^(3)装烟密度下烤后烟叶的整体品质最高,化学成分最为协调;50 kg/m^(3)装烟密度下,烤后烟叶的整体品质最差,但其总糖、还原糖、烟碱、总氮和类胡萝卜素类降解产物含量最高;65 kg/m^(3)装烟密度下,烤后烟叶的苯丙氨酸类降解产物、棕色化反应产物和新植二烯含量最高。

In order to explore the more suitable tobacco loading density for intensive baking in Fuzhou tobacco district,Jiangxi Province,using the middle leaf of the local cultivar Yunyan 87 as the experimental material,the appearance quality,physical characteristics,conventional chemical components,neutral aroma substances and sensory quality of flue-cured tobacco under four loading densities of 50,55,60 and 65 kg/m^(3) were compared.The results show that,the loading density has a great influence on the quality of flue-cured tobacco leaves;When the loading density is 60 kg/m^(3),the overall quality of flue-cured tobacco leaves is the highest and the chemical composition is the most coordinated;When the loading density was 50 kg/m^(3),the overall quality of flue-cured tobacco was the worst,but the contents of total sugar,reducing sugar,nicotine,total nitrogen and carotenoid degradation products were the highest;Under the loading density of 65 kg/m^(3),the contents of phenylalanine degradation products,browning reaction products and neophytodiene in flue-cured tobacco were the highest.
