Abstract:: ... Tapioca starch was modified using branching enzyme (BE) isolated from Bacillus subtilis 168 and Bacillus stearothermophilus maltogenic amylase (BSMA), and their molecular fine structure and susceptibility to amylolytic enzymes were investigated. By BE treatment, the molecular weight decreased from 3.1 x 10⁸ to 1.7 x 10⁶, the number of shorter branch chains (DP 6-12) increased, the number of longer ...
