A method of rapid enzyme maturing of fish, particularly herring, with a suitable salt content for instant consumption, by which the fish is filleted, skinned, trimmed and made open to diffusion by deep-freezing, optionally by salting or vacuum treatment, before, during or after filleting. The fillets are exposed to a brine having a temperature below 10<o> C, preferably below 5<o> C, and having a salt content which will give a salt concentration of from 4 to 8%, preferably 6%, in the finished matured fillet product. The brine further contains from 0 to 8% of sugar, seasonings and other substances that can have an influence on the taste of the products. The enzymes needed for the maturing process are added in the form of viscera, particularly appendixes (Pylorus caecae) in a natural, preferably finely divided form, or in the form of commercially available water soluble proteolytic enzymes or enzyme preparations. When an optimal product quality is obtained, which occurs after a maturing period of from 1 to 5 days, the enzyme activity is disrupted by deep-freezing or chemical inactivation in a manner known per se. |
