Seven different areas of salted fish were being used for investigating the volatile components by electronic nose technique. An e-nose technology was established through principal, linear discriminant analysis  and loadings analysis, and combined with sensory evaluation to analysis the quality of seven samples. The results showed that Qingdao-Shandong salty fish had the highest score of sensory evaluation. The principal component analysis  was more effective than linear discriminant analysis, and the content of total volatile base-nitrogen （TVB-N） plays an important role in distinguish salted fish.
