The raw materials Pteridium aquilinum starch was extracted by using a traditional wet-milling process. The effects of sugar on processing properties of Pteridium aquilinum starch were studied. Sugar enhanced pasting temperature. Glucose and sucrose raised viscosity and transmittance. Sugar improved freeze-thaw stability and sediment stability,with a lower percentage of supernatant, Pastes retrograded during 72h storage, Sugar reduced retrogradation tendency and it was more apparent when sugar density reached 20%. Sugar including glucose and ...
