Improved product quality and raw material utilization 

Fish is a highly nutritional raw material, and how it is processed affects quality and market value to a high degree. Our solutions let you maximize fish by-product utilization and product value.  

  • Enhance product quality with our closed processing systems. Minimal oxidation and moisture result in extended shelf-life.  
  • Increase the purity of your fish oil while preserving antioxidants and vitamins and minimizing oxidation and levels of free fatty acids (FFA). 
  • Increase fish oil yield with our proprietary high-efficiency decanter and separator solutions. 
  • Process your raw material in fully hygienic, food-grade solutions for protein and oil extraction. 
  • Produce low-fat, highly nutritional, food-grade fish flavours and proteins for the growing food and pet-food market. 
  • Maximize fish by-products and waste utilization by extracting high-value protein isolates and peptides through hydrolysation of fish processing by-products. 
  • Improve both quality and yield in surimi production, and start using alternative species, such as sardines, as raw material.
