This invention relates to a method for production on an industrial scale of the branched fructooligosaccharide indicated by the general structural formula below using microorganisms or an enzyme produced by microorganisms which belong to the genus Aspergillus, ##STR1## wherein in the formula above, m=0-10, n=0-8 and m+n=3-10.

Production method of branched fructooligosaccharides

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

Process for producing starch sugar which comprises contacting liquefied starch with amylase immobilized onto porous chitosan. Immobilized debranching enzyme can be used in combination with the amylase. The debranching enzyme is immobilized onto a specific support.
