土壤质地对皖南烤后烟叶中性香气成分含量及焦甜香风格的影响

Effect of soil texture on neutral aroma components content and burned sugar aroma style in flue-cured tobacco leaves in South Anhui province

取皖南3种不同质地土壤生产的烤后烟叶样品进行中性香气物质和常规化学成分含量测定,并进行单料烟感官评吸鉴定,结果表明,砂壤土各部位烟叶的类胡萝卜素降解产物、糖类氧化产物含量、中部叶的西柏烷类降解产物茄酮含量、下部叶的苯丙氨酸裂解产物含量水平相对较高。常规化学成分中总糖含量和烟碱含量均较高,糖碱比适宜,评吸认为其感官质量优良,焦甜香突出;水稻土下部和中部叶类胡萝卜素降解产物含量、中部叶茄酮含量偏低,而上部叶苯丙氨酸降解产物和类胡萝卜素降解产物较高,总糖含量较低,上部叶烟碱和总氮含量偏高,糖碱比偏低,焦甜香不显著,上部叶虽香气量大,但劲头偏大;粉砂土一般表现为上部烟叶类胡萝卜素降解产物含量偏低,总糖含量较高,但含氮化合物含量偏低,糖碱比偏高,评吸认为焦甜香弱,烟叶香气量偏小。

Tobacco leaves from 3 typical tobacco soils textures in south Anhui province were selected to investigate the differences in the content of aroma components and regular compounds in flue-cured tobacco and in the sensory evaluation on aroma quality.Results showed that on alluvial sandy soil,tobacco had high levels of carotenoid catabolites and sugar catabolites for all stalk positions,high levels of solanone for middile leaves,and high levels of phenylalanine catabolites for lower leaves.Both sugar and nicot...
