Changes of Corn Flour by Different Treatments
Abstract:
The properties of corn flour prepared by fermenting, wet-milling and extruding were investigated. The results showed that RVA parameters of the corn flours by fermenting compared with wet-milling decreased but enthalpies slightly increased. Extruded samples had no peak (RVA) and no differential scanning calorimetry (DSC) endotherm. In fermenting and wet milling starches a bimodal distribution of chain lengths( fractionⅠand Ⅱ) were found by gel permeation chromatography but extruded starches only one fraction.
