Abstract

"PROCESSO DE TRATAMENTO DE TABACO PARA REDUZIR O TEOR DE NITROSAMINA, E PRODUTOS PRODUZIDOS POR MEIO DESTE". Na presente invenção são descritos processos de redução do teor e prevenção da formação de nitrosaminas carciogênicas em plantas com folhas grandes colhidas, tais como,tabaco e maconha. Os processos são direcionados para sujeitar a planta à radiação de freq³ência em microondas ou mais altas, em tempos apropriados de ciclo de cura. Com tabaco, produtos adequados para consumo humano, tais como cigarros, charutos etc, podem ser produzidos,de acordo com a presente invenção, possuindo teores de nitrosaminas específicas,do tabaco em um par com tabaco verde recém-cortado. Em modalidades preferidas, os produtos de tabaco resultantes são secados, as folhas amarelo-douradas possuindo quase quantidades insignificantes de conhecidos carcinógenos NNN e NNK quando comparado com o tabaco convencionalmente curado."TOBACCO TREATMENT PROCESS TO REDUCE THE NITROSAMINE CONTENT, AND PRODUCTS PRODUCED THROUGH THIS". In the present invention there are described processes for reducing the content and preventing the formation of carciogenic nitrosamines in plants with large harvested leaves, such as tobacco and marijuana. The processes are aimed at subjecting the plant to microwave or higher frequency radiation, at appropriate curing cycle times. With tobacco, products suitable for human consumption, such as cigarettes, cigars, etc., can be produced, according to the present invention, having specific nitrosamine levels, of the tobacco in a pair with freshly cut green tobacco. In preferred embodiments, the resulting tobacco products are dried, the golden-yellow leaves having almost negligible amounts of known NNN and NNK carcinogens when compared to conventionally cured tobacco.
