Abstract
In a method for the production of an agent for modifying a smoke-flavor, ambroxide is contacted with a microbial culture to effect a transformation of at least a proportion of the ambroxide to a product comprising at least one oxygenated derivative of ambroxide. The said product may comprise at least one of the compounds A, B and C, each as defined in the specification. The respective Compound, (particularly Compound A), may be extracted from said product for incorporation with a smoking material. Thus a smoke-flavor modifying agent produced by the aforesaid method for incorporation with, or included in, a smoking material or smoking article may comprise at least one compound of the aforesaid group. The loading level of the said agent may be within a range of 0.1 to 100 parts per million or, suitably, of 0.5 to 10 parts per million, of the said smoking material.
