Preparation and slowly digestible properties of β-cyclodextrins (β-CDs)-modified starches

► β-CDs significantly increased the yield of slowly digestible starch (SDS). ► The optimum conditions for preparation of β-CDs-modified starches were obtained. ► β-CDs-modified starches showed intermediate predicted glycemic indexes (pGI). ► β-CDs-induced modification was one of promising techniques for preparing SDS.
