| Outline of Final Research Achievements |
For some polysaccharides retarding starch digestibility, their effects on in vivo glucose response of gelatinized potato starch were evaluated. One of water-soluble polysaccharides, which remarkably reduced the digestion of gelatinized potato starch, significantly reduced the postprandial blood glucose response in rats and dramatically increased the viscosity of gelatinized starch. These results imply that the increased viscosity contributes to reduction of starch hydrolysis and the blood glucose level in the initial stage of digestion by rats. In adding, the effects of food form and texture on starch digestibility were investigated for cooked rice, bread, and starch gels.
