Studies on the Property of Starch Sodium Dodecenylsuccinate

The paste property of starch sodium dodecenylsuccinate and corn starch was studied with Haake rotoviscometer and Brabender viscometer. The result showed that the thickening ability of starch sodium dodecenylsuccinate was better than that of corn starch. The emulsion stability of starch sodium dodecenylsuccinate was invcstigatcd by the mcthod of wcighting, comparcd with that of gum arabic and corn starch. The result indicated that the emulsion stability of starch sodium dodecenylsuccinate was better than that of corn starch and equal to that of gum arabic. The starch sodium dodecenylsuccinate and dextrin adding gum arabic was sued as the wall material in microencapsulation examination by the method of spray drying. The result showed that the microencapsulation efficiency using starch sodium dodecenylsuccinate was better than that using dextrin adding gum arabic.
