Abstract

Изобретение касается способов снижения содержания и предотвращения образования канцерогенных нитрозоаминов в собранных листьях растений, таких как табак. Эти способы предусматривают обработку растений микроволновым излучением и/или высокочастотным излучением в подходящие фазы стадии сушки. Что касается табака, то изделия, пригодные для потребления человеком, такие как сигареты, сигары и т.п., могут быть изготовлены в соответствии с настоящим изобретением с получением того же низкого содержания специфичных для табака нитрозоаминов, как и у свежесобранного зеленого табака. В предпочтительных вариантах получаемые табачные продукты представляют собой высушенные золотисто-желтые листья, характеризующиеся практически полным отсутствием известных канцерогенов NNN и NNK по сравнению с табаком традиционной сушки.Международная заявка была опубликована вместе с отчетом о международном поиске.The invention relates to ways to reduce the content and prevent the formation of carcinogenic nitrosamines in the collected leaves of plants, such as tobacco. These methods involve treating the plants with microwave radiation and / or high-frequency radiation in suitable phases of the drying stage. As for tobacco, products suitable for human consumption, such as cigarettes, cigars, and the like, can be made in accordance with the present invention to obtain the same low content of tobacco-specific nitrosamines as in freshly harvested green tobacco. In preferred embodiments, the obtained tobacco products are dried golden-yellow leaves, characterized by the almost complete absence of the known carcinogens NNN and NNK compared to traditional drying tobacco. The international application was published along with an international search report.
