Abstract. Astaxanthin (3,3'-dihydroxy-β, β-carotene-4,4'-dione) is the main carotenoid pigment found in aquatic animals, and has been used in food, cosmetic and medical application due to its high antioxidant activity. In this study, a new method using high pressure processing (HPP) to extract astaxanthin from shrimp (Litopenaeus vannamei) discards (shrimp shell and shrimp head) at ambient temperature was studied. The effects of hydrostatic pressure (0.1~600 MPa)，Liquid-to-solid ratio (10 to 50 mL/g), and pressure holding time (0~20 min) on the yield of astaxanthin were investigated by quadratic rotation-orthogonal composite experimental design. The quadratic effects of pressure, pressure holding time and Liquid-to-solid ratio were significant (p < 0.01, p < 0.05, p < 0.05 respectively). The optimal condition was as follow: pressure was 210 MPa, liquid-to-solid ratio was 32 mL per 1g, pressure holding time was 10 min, and the maximum yield of astaxanthin was 89.12 μg/g. Comparing to the conventional extraction method, HPP shows dominant advantages with higher yield and shorter extraction time. The use of HPP to extract astaxanthin from shrimp discards is a potential alternative to conventional methods.
