METHODS FOR REDUCING ONE OR MORE TOBACCO SPECIFIC NITROSAMINES IN TOBACCO MATERIAL.

摘要

There is described herein a method of reducing the amount of at least matrix-bound NNK in tobacco material comprising the steps of: (a) providing tobacco material comprising at least matrix-bound NNK; (b) optionally measuring the level of at least matrix-bound NNK in the tobacco material; (c) heating the tobacco material for at least about 30 seconds to a temperature of greater than about 110 degrees Celsius in the presence of a liquid or steam to release at least a portion of the matrix-bound NNK from the insoluble tobacco matrix of the tobacco material; (d) optionally measuring the level of at least matrix-bound NNK in the tobacco material following step (c); (e) optionally comparing the levels of matrix-bound NNK obtained in steps (b) and (d); and (f) identifying tobacco material in which at least matrix- bound NNK has been removed from the tobacco material.
