Full utilization of proteins from Lumpfish
The aim of the project was to develop new protein products from raw materials generated during the processing of grayling eggs. In this way, the aim was to extract even more value from the raw material by producing valuable protein products from grayling. The project examined the development of three products, 1) isolated protein for surimi, 2) dried protein as an additive and 3) hydrolyzed protein as an additive and / or dietary supplement. Protein isolates from grayling meat were difficult to isolate, but the results of bioactivity measurements of products from hydrolyzed proteins are promising for further research.
The aim of the project was to develop new products from lump fish to increase the yield and value of the catch. In the project the aim was to develop three types of products: 1) isolated proteins for surimi, 2) dry proteins as additives and 3) hydrolysed proteins as additives and / or food supplements. The project revealed that protein isolation from lump fish is difficult but hydrolyzed proteins showed promising bioactive properties.
