The project is in accordance with the project plan. Due to high research activities in 2020,there hase been somewhat less activity in 2021. In WP 3, the final products has been nutritionally characterised by chemical analyses. In WP 4, we have tested the pilot plant in the factory, and also performed shelf-life studies of the spray-dried peptide product.

Fishy odour and taste are the main obstacles for using hydrolysed marine peptides as a food ingredient in the human market. In this project we will, by an optimised novel process, produce odour and taste neutral hydrolysed marine peptides from salmon and pelagic raw materials, targeting the human ingredient market. First, in lab-scale studies we will screen for cost-effective proteases regarding protein yield in the enzymatic hydrolysis of marine raw materials. Based on the screening results we will select one or several protease(s), and in lab-scale studies further optimise the hydrolysing conditions by a multivariate design to maximise protein yield, but at the same time pay attention to avoid bitter taste in the hydrolysed marine peptides. Next, in lab-scale we will remove fishy odour and taste in the hydrolysed marine peptides, by a novel, patented enzymatic application. To achieve best possible results, we will utilise a multivariate design to optimise the novel enzyme's hydrolysing conditions. As a third step, in lab-scale we will optimise a filtration step, in which we produce fully soluble hydrolysates with a protein content > 90% on dry matter base, while retaining as much as possible of nutrients in the hydrolysates. Finally, the results from the lab-scale studies will be implemented in a novel pilot plant built at Biomega’s factory at Skaganeset. In addition to the novelty of producing odour and taste neutral hydrolysed marine peptides for the human market, one important aspect in the project is the valorisation of pelagic materials, making human grade ingredients from raw materials traditionally used in the fishmeal production and sold to the less value-added feed market. Thus, the project is set within a sustainability perspective, and complies with several of the United Nations Sustainability Development Goals.
