¹⁾ Enzymatic reaction was carried out at 40°C for different time intervals with 40 U/mL of amylase activity, and initial starch concentration was 5% (w/v).

²⁾ A, α-amylase; B, β-amylase; and G, glucoamylase.

³⁾ The D_c/D_g means that the ratio of surface pore to whole granule diameters of porous corn starch granules.

⁴⁾ Means of four replicates. The values with different letters of superscript (a-d) are significantly different at p<0.05.

⁵⁾ nd, not determined.
