A method of making beta-limit dextrin containing starch products is disclosed. The method comprises first treating fully or partially gelatinized starch with beta-amylase until a DE of 5-30 is reached, thereafter completely gelatinizing the resulting product as far as necessary and treating the resulting solution with alpha-amylase for a short period of time so that, as a result of the treatment with alpha-amylase, the DE of the starch hydrolysate is increased by no more than 3 units.

Method of making and applying beta-limit dextrin containing starch

A process for producing cyclodextrin from starch in which an aqueous solun of starch is subjected to the action of an active cyclodextrin glycosyltransferase and the reaction mixture containing cyclodextrin, starch degradation products and active enzyme is continuously subjected to an ultrafiltration process to effect passage of the formed cyclodextrin through the membrane, while retaining substantially all of the other starch degradation products and active enzyme, thus permitting more cyclodextrin to be formed in the retentate, which will then pass the membrane, collecting the aqueous solution of cyclodextrin and recovering the cyclodextrin.
