Natural Antimicrobials from Cloudberry ( Rubus chamaemorus ) Seeds by Sanding and Hydrothermal Extraction
We have developed an organic solvent-free process to enrich natural antimicrobials from the important Nordic Rubus berry species, especially from cloudberry. The process utilizes industrial berry byproducts as raw-material, and it is based on seed sanding technology and water-based extraction. The e...
