The kelp Saccharina latissima is characterised by high iodine concentrations. This can lead to adverse health effects if consumed in excess and represents a market barrier for cultivated kelp as food. Other potentially toxic elements (PTEs), including arsenic, cadmium, lead, and mercury, may also be present, and their concentrations should be minimised to ensure safety compliance. Therefore, efficient processing methods for PT...

Seaweeds must be stabilised shortly after harvesting to avoid rapid deterioration. To handle large amounts harvested during a short period, freezing and frozen storage until utilisation or further processing is one of the methods used industrially. The aim of this study was to assess the effects of different freezing and thawing procedures on Alaria esculenta by analysis of the chemical composition of the seaweed and the drip...
