It is necessary to cure tobacco after harvesting and before it can be consumed. Curing tobacco has always been a process necessary to prepare the leaf for consumption because, in its raw, freshly picked state, the green tobacco leaf is too wet to ignite and be smoked. In recent times, traditional curing barns in the United States are falling into disuse, as the trend toward using prefabricated metal curing boxes has become more and more prevalent. Temporary curing boxes are often found on location at tobacco farms.

Souza Cruz ensures to integrated producers the purchase of all tobacco produced. The acquisition process, however, involves a series of steps, involving mainly the determination of the amount of tobacco delivered to the company. Then, the burden is weighted and passes to classification, which is made in sensory manner. The agricultural technician responsible for the analysis assesses what was the position of the leaf - the value grows with the amount of nicotine - its color and maturity. The classification is then reported to the producer who follows the entire process. The amount to be paid by the bale is defined by a table previously disclosed. Producers are guaranteed to have their production purchased by Souza Cruz, but are not obligated to do so. After classification and confirmation of tobacco purchase, the bales are identified and sent to storage. At this stage, a robot developed by Souza Cruz in partnership with technology providers uses a reader to automatically recognize and organize each tobacco class. After separation, lots of bales are transported to a refrigerated warehouse.

Above all, do not believe that when the tobacco is harvested, the leaves are out of danger; the tobacco leaf stays a potential substrate for micro-organisms. Indeed many lesions may occur during their curing and storage and cause huge losses. The origins of these lesions may be related to the development of micro-organisms , the impact of agricultural mistakes made during cultivation or poor management of curing or storage of tobacco. When harvested, the tobacco leaves are mostly mature but still more or less green. Once they start to yellow, they are much more vulnerable and form an ideal natural substrate for many micro-organisms, especially bacteria and fungi. Among them, some of the pathogens attacking the plants during cultivation are observed but there are also others which occur on the surface of different organs of tobacco and partly form its phylloflora. Note that tobacco leaves may be polluted or contaminated in the field, from the soil or during air-curing in contaminated barns, from workers during harvesting and sorting or in the warehouse during storage.
Tobacco is the core component of our products. The three tobacco types are Virginia, burley and oriental. Other cigarette types include those made from dark or air-cured tobaccos , oriental-tobacco cigarettes , and kreteks, which contain cloves and are popular in Indonesia. Learn more about the art of blending by watching this video:. Tobacco begins its lifecycle as a seed sown in a specially constructed seedbed. Tobacco is harvested either leaf by leaf, in the case of Virginia and oriental tobaccos, or by the whole plant, in the case of burley. The next stage, curing, plays a major role in defining the leaf's final quality and character. Each tobacco type is cured differently: air-curing for burley, flue-curing for Virginia, and sun-curing for oriental.
Only low amounts of immunoreacting protein of smaller size could be detected in transgenic tobacco leaves indicating that the patatin protein is fairly stable in this heterologous environment. The size of the protein as well as the size of the RNA detected in transgenic tobacco leaves using a patatin-specific probe indicates that the patatin RNA was accurately processed in both leaf and stem tissue of tobacco.
It is widely accepted that seed storage proteins accumulate only in cells which have entered the cell expansion phase and do not continue to divide. Here we present data indicating that the accumulation of storage globulins in tobacco begins already during early embryogenesis in a period of sustained mitotic activity.

The flue-cured marketing season runs from August through December during which time approximately one billion pounds of tobacco arc sold. The tobacco marketing pattern in the United States creates a peak sales period lasting about six weeks during September and October, during which processors must purchase at a rate considerably in excess of their processing capacities in order to meet raw material requirements. In recent years, increasing purchases, combined with a shorter selling season and a reduction in suitable redrying facilities brought about by the increased use of threshing, have intensified this problem. Effects Of Storage: Tobacco as purchased can be stored for only a short period of time.
