Abstract

Chemical composition as the basic material component of tobacco leaves manifests itself both in their external appearance and in the smoking properties. Knowing the chemical composition of tobacco is of particular importance because leaves harvested at different stages of maturity have different chemical compositions.
When assessing the quality of tobacco based on its chemical composition, the balance of the components may play a more crucial role than their individual content.
Taking into consideration the prior knowledge, an experiment with tobacco type Prilep P 66 9 was conducted at the experimental field of the Scientific Tobacco Institute - Prilep, following a standard methodology.
Three variants were included in the trial - oriental tobacco harvested during technological maturity, before technological maturity (green state), as well as tobacco leaves harvested after technological maturity (overripe state). The aim of this study was to perceive the quality of tobacco depending on the time of harvest.
Considering the great importance for the tobacco quality, we decided to analyze the following important chemical properties: nicotine, nitrogen and total nitrogen, proteins, soluble sugars, mineral substances and Schmuck's number.
The ratio between soluble sugars and proteins is used as an objective indicator of tobacco quality.
Keywords: oriental tobacco, Prilep 66 9 type, chemical properties, maturity.
