The Effect of Amylase on the Phase Transition Properties of Starch Granules

HUANG Qiang,LI Lin,FU Xiong,HE Xiao-wei(Institute of Light Industry and Chemical Engineering,South China University of Technology,Guangzhou 510640,China)  
The phase transition properties of starch granules treated by Bacterial Amylase Novo(BAN),Gluco amylase(GA) and Fungal amylase(FA) were studied by differential scanning calorimetry(DSC) and Brabender viscograph.Results show that T0,Tp,Tc and enthalpy of enzyme treated starch(ETS) first increases and then slightly drops respectively with increasing degree of hydrolysis,while the enthalpy of BAN treated starch decreases and than raises with increasing degree of hydrolysis.It concludes that amorphous is mainly degraded by GA and FA treatment,while amorphous and crystalline is degraded by BAN.Investigated by Brabender viscograph,the peak viscosity of ETS paste took on downtrend.While the temperature of beginning gelatinization and peak viscosity took on uptrend.
