The desmutagenic substances consist of a fibrous constituent of food which was produced from corn fibers. These substances have a function of inactivating mutagens which occur in our daily life environment, for example, dinitropyrene, pyrolysate mutagens of food or the like. The process for producing these substances comprises the step of subjecting corn fibers to a treatment process to remove starch, protein and other digestable substances therefrom, the treatment process being an enzyme treatment, chemical treatment or physical treatment or a combination thereof.

Desmutagenic substances and their production process

Anti-mutagenic factor is fractionated from cabbage juice. The factor is a protein having an M. W. of about 48,000 when determined by the SDS-gel electrophoresis and shows characteristic adsorptions at 280 nm and 404 nm. The factor substantially inhibits the mutagenic activity of various mutagens such as pyrolysates of amino acids.
