The preparation process of octenyl succinic anhydride modified potato starch in a pilot scale was designed. The conditions of process were optimized by comparing the structures and properties of the pilot production products and laboratory products. The optimum parameters were screened as starch latex at 40 %, amount of OSA was 5 %, pH7.5~8.0, stirring rate at 200 r·min~(-1), crossing temperature at 30 ℃ and crossing time for 4 h, under this condition, the substitution degree of prepared OSA-starches was 0.018 62.
