以普通玉米为原材料，采用不同温度蒸汽直热处理的方法，对其理化特性进行研究。结果表明，随着蒸汽直热温度的升高玉米淀粉粒径减小，色泽逐渐变浅，粘度增加，直链淀粉含量增加，沉淀率也随着蒸汽直热温度的升高而降低，因此蒸汽直热处理能够减小玉米浆分子颗粒的大小并有效的增加玉米浆的稳定性和悬浮性。
Different methods of heat treatment steam temperature jet cooking on the normal corn product''s physic-chemical properties were investigated. The results indicated that the average size and the rate of precipitation of the corn steep liquor decreased as the steam jet cooking temperature rose , while the viscosity and amylase content of liquor increased, and the liquor color became light gradually. As a result, the steam jet cooking can reduce the particle size of corn steep liquor and effectively increase in the stability and suspension of corn steep liquor.
