Purine, taurine, cholesterol and antioxidants in pressurized squid were analyzed.
Pressurization and storage did not affect the taurine, EPA, DHA, Mn and Cu levels.
Pressurization at 600 MPa caused the maximum loss of cholesterol, purines and Fe.
At 600 MPa, Vitamin B2, DPPH, reducing power and TBARS values were minimally reduced.
Cholesterol, reducing power, or VA showed no obvious differences at 200 and 400 MPa.
