外文摘要：To explore the adsorption behaviour of high pressure carbon dioxide (HPCD) in protein, shrimp surimi was made into a cylinder, a radial adsorption prototype was established, and the adsorption mass of HPCD in shrimp surimi was measured using a adsorption instrument with a magnetic suspension balance. The adsorption mass measured directly by the instrument was the excess adsorption mass of CO2 in shrimp surimi and not the actual adsorption mass. The excess adsorption mass was corrected to the absolute adsorption mass. The absolute adsorption mass more accurately represented the CO2 adsorption capacity of shrimp surimi. Under isothermal conditions, the absolute specific adsorption increased and reached a maximum near the critical point (7.38 MPa) of CO2 and gradually decreased and stabilised with the increase in pressure. Under isobaric conditions, the absolute specific adsorption decreased with increasing temperature. Maximal absolute specific adsorption ranged from 46.99 to 99.49 cm3/g at 35-60 degrees C.
