  • Publication number: 20190177758
    Abstract: Disclosed is a method for modifying starch to slow down the digestion rate of modified starch. The present invention utilizes two-stage GBE treatment to convert the long straight-chain starch molecules into highly branched molecules with compact structures so as to decrease the digestion rate of the starch. During the two-stage treatment, granular starch was first treated with GBE, the treated starch was gelatinized in boiling water, and the gelatinized starch was treated with GBE for a second time, leading to an enhanced effect of GBE modification. Compared with the one-staged GBE modification, the two-stage GBE modification can further increase the content of slowly digestible starch in the modified starch and thus decrease the digestion rate of starch.
