Foods in which alpha-cyclodextrin is to be used:
Alpha-cyclodextrin may be used for increasing the,diejai!y fiber content of solid,
semiliquid
and liquid foods alike. Because of its ability to form complexes with certain organic
molecules, alpha-cyclodextrin may also -fulfill certain food-technological functions, e.g. as
a flavor adjuvant; .il coloring adjunct; or a carrier, stabilizer, or solubilizer of certain
vitamins (zkr,et inol acetate, vitamins K1 and C, riboflavin, and p-carotene) and fatty
acids.

Use Level Food Category
A few percents in most products, eg. 5% in breads, rolls, cakes, biking mixes etc.

Method of Manufacture of alpha-cyclodextrin
Alpha-cyclodextrins are formed by the action of cyclodextringlycosyltransferases
(CGTase) on starch. CGTases are amylolytic enzymes which are produced naturally by
different strains of Bacilli and other species of bacteria. Cyclodextrins are isolated from
the enzymatic reaction mixture either by the “solvent process,” in which a suitable organic
substance is added to form an insoluble complex with the cyclodextrins, or the “non-
solvent process.
