摘要: 玉米全淀粉糊化后直接经β-淀粉酶水解制得β-极限糊精。对β-极限糊精的颗粒形态、不同影响因素下的黏度特性进行了研究。结果表明,β-极限糊精颗粒表面光滑,但形貌不规则;增大浓度、添加蔗糖,β-极限糊精的黏度升高,但添加氯化钠、酸、碱,β-极限糊精黏度降低。

Abstract: β-limit dextrin was produced by β-amylase enzymatic hydrolyzed on corn starch paste directly.Particle shape and viscosity characteristic of β-limit dextrin have been discussed.The results showed that the surface of β-limit dextrin particle is smooth,but its shape is irregular.Adding concentration of β-limit dextrin and adding cane sugar increase the viscosity of β-limit dextrin,while adding sodium chloride,acid and alkali decrease that.

Key words: viscosity; corn starch; &beta, -amylase; &beta, -limit dextrin;
