Novel cascade technology for optimal utilization of animal and marine by-products


Annually, large quantities of by-products are produced from the animal and marine food processing industry. Cod heads and mechanically deboned poultry residues are two of the most underutilized by-products in Norway. These by-products are complex materials consisting of components such as proteins, fats, minerals, and other nutrients of high nutritional value for a globally growing population. If successfully processed into refined and tailor-made products, there is a great economic potential for high-paying markets. The proteins alone has an estimated 25 to 65% increase in sale price if processed optimally, as compared to the raw material. In recent years, enzymatic protein hydrolysis (EPH) have gained significant attention as a mild and versatile processing technology of animal and marine by-products. However, currently this technology cannot be used to take full advantage of the multitude of components in the by-products. In this project, we will develop a novel cascade bioprocessing technology that will solve this challenge. The cascade will constitute a combination of several different processing steps, each one aimed at giving separate products with the highest possible yield and quality. To be able to achieve this goal, we will combine research from several different scientific disciplines, namely bioprocessing and enzyme stabilization technologies, computer simulation and modelling, spectroscopy and analytical chemistry. By adopting the cascade bioprocessing technology, potential products from the cascade bioprocess can be formulated into a multitude of refined high-quality products for high-paying markets. To our knowledge, there are currently no companies in the world using cascade bioprocessing to facilitate full utilization of marine and animal-based by-products. In the future, our industrial partners and the rest of the by-product processing industry will have the desired technological for total utilisation and optimal value-creation of by-products.
