This paper introduced the theoretical and productive achievement in natural pigment, including the development of supercritical fluid extraction (SCFE). Then the application of SCFE in natural pigment was mainly described .The type of pigment was firstly taken into consideration, in order to explore the feasibility of SCFE extracting different kind of pigment. The related extracting theory and experimental research were summarized in the following content. In the end, the article explored the weakness of SC...
