From the results it can be concluded that WL, SG, RR and texture of sweet purple potatoes were increased while increasing concentration of sucrose and CaCl2 during the osmotic process, while moisture, aw, color, TPT, TAT and TAA level of purple sweet potatoes was decreased during the process when the concentrations of sucrose and CaCl2 were increased. The difference concentrations of sucrose and CaCl2 in the osmotic solutions was significantly affected the quality of purple sweet potatoes. The use of CaCl2 might increase the calcium content of purple sweet potato and preventing some diseases and as well as strongther the texture of potatoes against the destruction from the osmotic solution. The results proven that potatoes were treated by 50% sucrose solution with 2% CaCl2 is better on the purple sweet potato quality due to minimal lose of physio chemical characteristics as compared to a very low and a very high sucrose and CaCl2 concentrations.
