StableSea - Bærekraftig Tarestabilisering gjennom Alternative Konserveringsmetoder

Offentlig prosjektsammendrag

StableSea addresses raw material stability in seaweed biorefinery. While the conventional seaweed industry relies on direct processing of fresh raw material, preservation with formaldehyde or processing previously dried raw material (energy intensive). The primary objective of this project is to develop and validate sustainable, formaldehyde-free preservation techniques, using innovative combinations of mild organic acids, natural antimicrobials and physical treatments, to inhibit microbial/enzymatic degradation while preserving chemical properties of high-value compounds like alginates and fucoidan. SEC-MALS, viscometry, HPLC, microbial count and NMR will be used to evaluate preservation methods. Additionally, a novel Infrared/Raman spectroscopy method for cost-effective process and quality control will be developed, providing a fast and non-destructive alternative to HPLC and NMR (e.g. alginate M/G ratio), generating novel protocols for efficient and sustainable seaweed biorefinery.
