Data are mean ± standard deviations, n = 3. Values in the same column with different letters are significantly different (p < 0.05); NS, PDA 0 h, PDA 5 h, PDA 10 h, PDA 15 h, PDA 20 h, and PDA 25 h indicate native starch and pullulanase debranching in different treatment times (h) combined with autoclaving starch.
