WANG Yu-juan;LI Xiao-lei;FU Jing-chao;LI Dan;Key laboratory of Agriproducts Processing Technology at Jilin Provincial Universities, Changchun University;  
The digestibility and retrogradation of pullulanase-hydrolyzed cassava starch were investigated. The results showed that ready digestible starch and slowly digestible starch content of modifi ed starch, with the addition of enzyme at 120 U/g starch, reduced to 25.45% and 31.32%, respectively(P0.05), and the resistant starch content increased from 16.20% to 43.22%(P0.05) compared with those of controls. The gelatinized enthalpy of cassava starch with the treatment of pullulanase changed from 8.75 J/g to 2.77 J/g(P0.05) after the storage at 4 ℃ for 21 d. Pullulanase-hydrolyzed cassava starch had lower digestibility and retrogradation.
