Amylose content and the average degree of polymerization (DP) are important factors in the formation of resistant starch (RS). Based on corn starches,sweet potato starches, pea starch,mung bean starch,the method of pullulanase in con-junction with termostable α-amylase was used to produce resistant starch and to change the amylose content and degree of polymerization. The relationship of DP,Amylose content and the yield of RS was analysised. It illustrated that the yield of RS and amylose content were positively correlated. The average degree of polymeri...
