摘要
以玉米淀粉为对象,研究了超高压微射流对玉米淀粉的机械力化学效应,同时探究了机械力化学效应对玉米淀粉糊化性质的影响。结果表明,在超高压微射流的机械力作用下,淀粉颗粒被破碎成无数个不规则的小颗粒,淀粉粒度减小,且随着压力的增加,破碎程度增大。同时经过超高压微射流的机械力化学效应作用后,玉米淀粉的布拉本德粘度减小,且随着压力的增大,减小幅度增大。但超高压微射流对玉米淀粉的热粘度和冷粘度稳定性影响不大。
The mechno-chemical effects of high pressure microfluidization on corn starch and its effects on gelatinization properties of corn starch were researched. The results showed that the corn starch granules fell to pieces after HPM treatment, the granularity reduced and the brabender viscosity reduced. With the pressure of HPM increasing,the effects became more obvious. But the hot viscosity stability and cold viscosity stability of corn starch didn＇t be effected by HPM treatment.
