دراسة تاثير التخزين الطبيعي و التخمير الاصطناعي في التركيب الكيميائي للاوراق الخام في اصناف التبغ برلي ـ فرجينيا ـ بصما ـ بريليب المصنعة محليا

This research was aimed to study the effect of natural storage of tobacco, or natural fermentation on the chemical composition related to quality of leaves. It also studies the effect of artificial fermentation under controlled temperature and relative humidity on that composition. These changes were continued during 3 years in warehouses of General Company of Tobacco in Lattakia, Kordaha, and Aleppo. The results showed improvement in quality of stored tobacco for 2 years, associated with starch conversion to sugar, increase in sugar, reduction in proteins, loss of nicotine. However, a reduction in quality occurred after 30 months of storage. Finally, the artificial fermentation was not effective enough for improving tobacco quality.
