Abstract: The effects of mainly processing operations such as color protection,harding,seasoning,frying on the quality of fried purple sweet potato were investigated by single factor,and the processing operations were optimized by orthogonal and uniform test designed methods in this study. The results showed that the optimal process conditions are using citric acid 0.6% and 0.3% VC in the color protection,0.4% CaCl2 for 20 min in the harding,immersing in 8% sucrose solution for 15 min and frying at 180℃ for 20s.

Key words: purple sweet potato, fried purple sweet potato, color protection, harding, seasoning
