  • Patent number: 4780149
    Abstract: 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.
