Fish processing enzymes

Fish processing generates valuable byproducts that are high in protein and lipids, such as viscera, skin, tails, heads and frames

 The disposal of these nutrient-rich byproducts can often increase costs. By using enzymes to valorize byproducts, processors can potentially obtain additional revenue from nutritional supplements, ingredients for pet food, biodiesels, fertilizers, agricultural products, animal and fish feeds.
Many processors do not capture the full value of these byproducts. This may be due to inefficient secondary processing and over-reliance on mechanical, heat or chemical methods. Enzymes can enhance the quality and value of fish processing byproducts, optimizing time, energy and resources while also increasing revenue.

Key benefits

  • Increase yield
  • Improve extraction
  • Convert by-products into valuable ingredients
