| Abstract: | Low viscosity Starch Sodium Octenylsuccinate is a good microcapsules wall material. The technical conditions of preparing it by the means of two enzyme was studied in this article. When esterify starch slurry was 20% and α-D-glucan glucanohydrolase’s dosage was 6 SKBU/g, the dosage of α-D-glucoside glucohydrolase is the most important factor affecting the capabilities of it, next the operation time of α-D-glucoside glucohydrolase, last the heat preservation time of α-D-glucan glucanohydrolase. The best technical condition was: α-D-glucan glucanohydrolase’s operation time 4 minutes, α-D-glucoside glucohydrolase’s dosage 0.2 GAU/g and operation time 2.5 hours. Under this condition, the DE value of it was 30 and the fluidity of it was 80. |
