Study on Relationship between the Main Nitrogen Compounds and Sensory Quality in Flue-cured Tobacco Leaves

The objective of this paper is to study the effect of nitrogen compounds substances on the sensory quality of tobacco leaves. The effect of the main nitrogen compounds on tobacco sensory quality in flue-cured tobacco leaves were reviewed in the paper. The main nitrogen compounds of upper flue-cured tobacco leaves from main planting zones china in 2011-2014 were analyzed.The negative impact of the higher total nitrogen content on the sensory quality of tobacco was greater than the higher nicotine content.Reducing the non-nicotine nitrogen of content is one of the ways to improve the usability of the upper flue-cured tobacco.
