Sterilisation process by means of heat treatment for preserving the ink of coleoid cephalopod molluscs

Abstract

A sterilization process by means of heat treatment to preserve the ink of coleoid cephalopod molluscs includes the steps of homogenizing and first heat treating (1) the ink in a reactor for pasteurising treatment in which a temperature of at least 70° C. is attained for over 10 minutes; and cooling (2) the homogenized ink in a tank set to a temperature of below 30° C. and retaining the ink in the tank to lower its temperature. The process also includes the steps of continuing by filling, turning, blowing and marking (3) the expiry dates; and second heat treating (4) the ink in an autoclave in which a heat treatment is performed to achieve a sterilization temperature greater than or equal to 110° C. for a predetermined time based upon the quantity to be canned.
