ignificant amounts of rest raw materials are generated

throughout the value chain of seafood processing. Although

effort has been made on development of technology to utilize

these raw materials, there are still huge amount that goes to

waste. These include fractions with potential as e.g. food, feed

and pharmaceuticals and are generally rich in functional proteins,

lipids and carbohydrates. As an example; if whitefish fillet is

the main product, as much as 50% of the biomass in the catch

is regarded as rest raw materials or waste. Also filleting of fatty

species such as pelagic fish and salmonoids generate valuable

cut-offs and viscera. So, while the marine fatty acids are in short

supply worldwide, significant lipid-rich fractions goes to waste

throughout the value chain when producing seafood. Upgrading

this biomass for the growing world population and aquaculture is

a key area in the circular economy and optimal utilization of the

global marine resources. Several factors play a role in the circular

economy and gaining the total picture of reducing foodwaste. I will

primarily focus my talk on the biotechnology aspects of utilization

and demonstrate how these complex raw materials changes

fast due to its high susceptibility to biochemical degradations.

Biotechnological processes might trigger the potential of higher

utilization of the biomass. I will visualize technology from raw

materials into bioactive components such as protein and peptide

component, lipid and lipid components and also carbohydrate

rich components for example from utilization of macro algae.

Furthermore, I will include the sensory aspects of the rest raw

materials as marine ingredients, documented health effects and

demonstrate analytical techniques to understand the value of the

products.
