Technological Study on Tobaccos of Basmi Group Variety Grown in Different Regions of Bulgaria

Abstract

The quantities of the origins that are being produced, the varieties of traditionally wellknown high quality, respectively, for the time being cannot meet the demands of the tobacco processing companies and of the large international cigarette manufacturers, who purchase these tobaccos. Improvement of zoning and variety restructuring may lead to the achievement of certain enlargement of the origins. Thus, it will increase the opportunities to provide stable quantities of similar quality tobaccos, of which uniform export batches are prepared. This study aims at making a technological assessment of the quality indicators of varieties of Krumovgrad origin, grown in certain regions in Bulgaria and comparing them to those grown in the traditional regions or the so-called "typical" tobaccos of such subgroup. The comparison of tobacco quality was made on the basis of the assessment of the technological indicators: physical indicators; chemical composition of tobacco and tobacco smoke; "image" taking; organoleptic assessment. It was established keeping of the general character in the expression of the quality of the different varieties of Krumovgrad subgroup variety, grown in the studied regions and as a matter of fact, their assessment didn't demonstrate any significant differences. The influence of the genetic factor (variety) is clearly expressed with the varieties of the origin, i.e. it proved to be adaptive to the new conditions.

Complex evaluation of the quality of introduced and local varieties of Virginia flue-cured tobacco in Bulgaria

“…The assessment and interpretation of the detected differences between the numerical values of the chemical indices of the varieties (nicotine, reducing sugars, total nitrogen, ash, smoke nicotine, and tar), as well as the value range for defining the respective chemical index level (low, medium, high), were according to the criteria specified previously [21,22]. Thus, the samples within a series were considered different if the deviation between the respective values was within or above the range cited.…”

“…The coefficients of importance (relative weight) of those indices were defined in advance by the expert panel. The final rating of the varieties was obtained by calculating the individual values of a "quality index" and the total score of quality indices; the lower index score indicated higher rating, and respectively, better quality [6,21,22].…”
