HMTThe optimum conditions for forming high concentrations ofSDS fraction in waxy potato starch formed by HMT were previ-ously reported (Lee et al., 2012). The original moisture contentof the waxy potato starch used was measured 12.7% accordingto the AACC 44-15A procedure (American Association of CerealChemists, 2000). The moisture content of the waxy potato starchwas increased to 25.7% by adding the appropriate amount of dis-tilled water. The starch sample was mixed thoroughly with thewater in a glass container, sealed and left overnight at ambienttemperature to equilibrate the moisture content. The heat treat-ment was performed in a forced air oven at 120◦C for 5 h 20 min.Then, the container was opened and the sample was air-dried touniform moisture content (∼10%).
