Research on enzymatic hydrolysis to ethanol's protect non-crystal granular corn starch by α-amylase

TIAN Jing-fu, ZHANG Ben-shan, WANG Bin (College of Food Engineering and Biotechnology, South China University of Technology, Guangzhou 510640)  
Non-crystal granular corn starch is a special starch modality, possessing granule quality but not crystalline. Through granule surface of analysis on non-crystal granular corn starch, interior crystalline configuration of granule is demolished and disappeared, granule surface happens magnitude transformation, takes on reticulate configuration, exists obvious detonation hole. Using non-crystal granular corn starch as stuff, carries out hydrolysis through α-amylase in condition of 30 ℃. Comparing with corn starch in the same condition, reaction activeness is enhanced infinitly. The factors effect DE value such as quantity of amylase, temperature, time, was studied. activity and it's hydrolysis rate of hordein were highier in both of internal malting barley. So the internal barley has potential to make high-quailty malt.
