The water absorption capability of native canna starch was low at0.8 g/g starch, whereas that of swollen starches was significantlyincreased (4–5 times). Canna starch swollen at 68, 69, and 70 ◦C hadwater absorption capabilities of 3.6, 3.7, and 4.1 g/g starch, respectively. For the frozen-swollen starches, the absorption capacityincreased with increasing heating temperatures. The starches heated at68, 69, and 70 ◦C had water absorption capabilities of 2.8, 3.5, and 5.1g/g starch, respectively. The highest water absorption of starch swollenat 70 ◦C, followed by freezing, was likely due to its loose structure andthe highest level of retrogradation by highly dispersed amyloses. Thewater absorption capability of HMT canna starch was comparable to thatof native starch (0.8 g/g starch). The swollen HMT starches heated at
