摘要：
FLAVORING OILS WITH REDUCED SULFUR CONTENT AND ITS USE IN ORAL TREATMENT COMPOSITIONS. The present invention relates to flavoring oils which include the flavors of mint, fruit and spices which are specially processed to eliminate low molecular weight sulfur compounds, particularly dimethyl sulfoxide (DMSO), which has been considered the main precursor. of unpleasant odor species such as dimethyl sulfide and methyl mercaptan. These unpleasant odor species are produced via flavoring oxidation-reduction reactions and other components of the composition. The preferred method of processing is aqueous rinsing, which has the advantages of being simple, inexpensive and easy to implement, while importantly avoiding desirable process problems and subjecting flavoring oils to extreme conditions that may destroy other components and result in undesirable changes in taste and odor characteristics. Other processing methods for selective removal of unwanted components include (1) distillation for removal of low boiling polar components, (2) filtration by selective adsorption of sulfur compounds, (3) countercurrent extraction and (4) column chromatography. Processing methods may optionally be followed by reengineering to read the desired components that may have been removed or altered during processing. Specially processed flavoring oils are particularly useful for oral care compositions comprising chemically reducing components, such as stannous ions, which react with sulfur-containing compounds to produce unpleasant odor products.ËLEOS FLAVORIZANTES COM CONTéUDO DE ENXOFRE REDUZIDO E SEU USO EM COMPOSIçõES PARA TRATAMENTO BUCAL.
