Abstract

"PROCESSO APERFEIçOADO PARA TRATAMENTO DE TABACO PARA REDUZIR TEOR DE NITROSAMINA, E PRODUTOS PRODUZIDOS DELE" Um processo de tratamento de tabaco para reduzir o teor de, ou evitar a formaçào de, nitrosaminas nocivas, que são encontradas normalmente no tabaco é descrito. O processo inclui a etapa de submeter pelo menos uma parte da planta, enquanto a parte não está curada e está em um estado suscetível a ter a proporção de nitrosaminas reduzida, ou a formação de nitrosaminas impedida, a um meio controlado capaz de proporcionar uma redução na proporção de nitrosaminas, ou impedir a formação de nitrosaminas, por um tempo suficiente para reduzir a proporção, ou evitar substancialmente a formação, de pelo menos uma nitrosamina, em que o meio controlado é proporcionado por controle de pelo menos um de umidade, velocidade de variação de temperatura, temperatura, fluxo de ar, nível de CO, nível de CO~ 2~ e disposição da planta de tabaco. Os produtos de tabaco e um aparelho para produzir esses produtos de tabaco também são descritos."IMPROVED PROCESS FOR TREATING TOBACCO TO REDUCE NITROSAMINE CONTENT, AND PRODUCTS PRODUCED FROM IT" A tobacco treatment process to reduce the content of, or prevent the formation of, harmful nitrosamines, which are normally found in tobacco, is described. The process includes the step of subjecting at least a part of the plant, while the part is not cured and is in a state susceptible to having the proportion of nitrosamines reduced, or the formation of nitrosamines prevented, to a controlled medium capable of providing a reduction in the proportion of nitrosamines, or prevent the formation of nitrosamines, long enough to reduce the proportion, or substantially prevent the formation, of at least one nitrosamine, in which the controlled medium is provided by controlling at least one humidity, speed of temperature variation, temperature, air flow, CO level, CO ~ 2 ~ level and tobacco plant layout. Tobacco products and an apparatus for producing such tobacco products are also described.
