Mutagene activity of standards of some newsynthesized food flavours is studied: a flavour “Chocolate” showed strong gentoxic activity, which appeared in toxicness of megascopic in 10 times day’s dose, increase of level of chromosomal aberation under the action of other doses and decline of mitotical index; flavour “Prunes” induced appearance of chromosomal mutations at the action of possible day’s dose and dose megascopic in 10 times, increases of relative duration of profase. Among chromosomal aberations the chromosomal are educed and chromatid fragments, dicentric chromosomes. Under act of flavours “Mint” and “Vermouth” of chromosomal aberrations and changes in relation to a mitotical index are not showed.
