Pre-processing of raw materials (WP2) will investigate methods for stabilisation and separation of rest raw materials (RRMs) at slaughterhouses prior to further processing. The pre-processing of RRMs will be performed at a fish processing factory and will demonstrate the possibility to stabilise the RRMs to establish future business cases.

The challenge
Rest raw materials (RRMs) have limited shelf-life due to high rate of biochemical reaction and microbial activity. The value chain of the most types of RRMs is limited to fish oil extraction, fishmeal and biogas. The reason for this is absence of business cases and system solutions for efficient pre-treatment of RRMs at fish processing factories and slaughterhouses.
Work package objectives
- Develop sustainable and safe fractioning strategy of RRMs for production of food-grade products
- Determine methods and design efficient process of RRMs stabilization by chilling and freezing
- Determine optimal parameters of hydrolysation process and oil separation for selected types of RRMs. Develop stabilization of FHP using evaporation and freeze-concentration methods.

Work package lead
