Starch when being heated. Cause a change in the inside of the starch granule (molecular) starch granule) (A) due to the heat destruction of hydrogen bonding in molecules of the Star starch in starch granule. Polymer line of amylose (amylose) and amylopectin.Compact in the starch granule is relaxed, and combined with the surrounding water. resulted in the change of style appearance, starch granule swelling. And viscosity of starch increased continuously in the temperature range of about 60-70.The characteristics of water flour to thicken (starch) paste). Viscosity will increase until the point of starch grain swell and peak viscosity maximum (maximum) visicosity) (point of B), then the starch granule is broken to the top.There will be retrogradation up slowly, and increased when the time will be long on crystalline new
