Abstract: Feasibility on inclusion complex of saponification product of Haematococcus pluvialis with β-cyclodextrin was studied with astaxanthin content as the quality evaluation criteria. As the results,inclusion rate reached 90% at optimized conditions, and the content of astaxanthin in the saponification of H.pluvialis have no significant change. The stability of astaxanthin reach the requirements as medicine and health food raw materials in the accelerative experiment of stability at 50℃, 75% relative humidity. The results showed that this method is feasible.

Key words: Haematococcus pluvialis, astaxanthin, saponification, β-cyclodextrin, inclusion rate, stability
