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.
