Abstract: Ginger is usually by preserved salting,but in the processing,salt needs removing to between 3% and 5.5%. In this study,the immersion method was used to desalt and the desalination process was optimized by orthogonal test with contents of gingerol and salt as test indexes.The results showed that the best conditions of desalination technology are as follows: solid-liquid ratio 1:4,temperature 30℃,and soaking time 40 min.

Key words: ginger salt blank, gingerol, salt, desalination
