Glycemic Response to Corn Starch Modified with Cyclodextrin Glycosyltransferase and its Relationship to Physical Properties

Dura, A., Yokoyama, W., Rosell, C. M.·2016·Plant Foods for Human Nutrition

Abstract

Corn starch was modified with cyclodextrin glycosyltransferase (CGTase) below the gelatinization temperature. The porous granules with or without CGTase hydrolysis products may be used as an alternative to modified corn starches in foods applications. The amount and type of hydrolysis products were determined, containing mainly β-cyclodextrin (CD), which will influence pasting behavior and glycemic response in mice. Irregular surface and small holes were observed by microscopic analysis and differences in pasting properties were observed in the presence of hydrolysis products. Postprandial blood glucose in mice fed gelatinized enzymatically modified starch peaked earlier than their ungelatinized counterparts. However, in ungelatinized enzymatically modified starches, the presence of β- CD may inhibit the orientation of amylases slowing hydrolysis, which may help to maintain lower blood glucose levels. Significant correlations were found between glycemic curves and viscosity pattern of starches.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Cyclodextrins have glycosidic bonds that salivary amylases can hydrolyze slowly due to thermodynamic parameters, and therefore have very low glycemic indexes and provide a longer time of glucose supply to the bloodstream.

    “Cyclodextrins have glycosidic bonds that salivary amylases are able to hydrolyze but they act slowly due to thermodynamic parameters [76]; therefore, cyclodextrins have very low glycemic indexes and provide a longer time of glucose supply to the bloodstream [77,78].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
