Protease enzymes can help you reduce waste and get more out of your animal co-products by breaking down proteins into smaller peptides and amino acids.


Add value to your final products

One of the major goals of the seafood-processing industry is to add value to final products, including the ready-to-eat or low preparation seafood products that are increasingly popular. In fish-fillet production, only a fraction of the available fish is used, and the rest is often discarded as low-value coproducts or used as animal feed. Instead these can be used to create a new higher value stream.  

Increase yield and save costs

The enzymatic process increases yield and develops higher-quality fish-derived products. This gentle but highly effective process reduces viscosity and thus saves on energy use. It reduces cleaning costs, since treated fish is less likely to stick to surfaces. 

Protease enzymes are also used in the preparation of surimi, a popular seafood ingredient made from fish flesh that has been deboned and minced. The proteolytic activity of microbial enzymes helps to remove excess fat and connective tissue, as well as solubilize myofibrillar proteins to improve gelation properties. 

Maximize the value of co-products

Maximize the value of co-products

With Novozymes enzymes, processors gain an efficient tool to maximize the value of seafood. Enzymes let you convert low value co-products into high-value protein-rich ingredients, including fish and seafood protein extracts (FPEs), natural flavors and flavor enhancers.

You can create good-quality flavored stocks, broths and bouillons, as well as a clean bone fraction suitable for gelatin processing. Any type of seafood can be used, including all types of fish, crab, lobster, clams, krill, shrimp, langoustine, and more.
