Abstract :
During 2011 and 2012, on the experienced field of Scientific Tobacco Institute in Prilep experimental plots were set with oriental tobacco type Prilep (variety P-66),type Jaka (variety Jk-125/3) and type Basma (variety Basma-82). Nicotiana tabacum L. which is the subject of biochemical - technological analysis is an important crop spread widely in the world. The research results indicate negative correlation of the fermentation processes and the proportion of carbohydrates, which contributes the decrease of tobacco quality. Increased hydrolysis due to prolonged fermentation causes significant reduction in the catalase activity. Nevertheless, the concentration of H2O2 converted into non-toxic products (H2O and oxygen) is depended upon the duration and the conditions of the fermentation processes. Proteins and nitrogen in fermented material increased over prolonged fermentation. This study confirms that prolonged period of fermentation of tobacco raw reduces the quality of oriental tobacco.
