Effects of drying on the nutrient content and physico-chemical and sensory characteristics of the edible kelp Saccharina latissima
Stévant, Pierrick Francois Denis; Indergård, Erlend; Ólafsdóttir, Aðalheiður; Marfaing, Hélène; Larssen, Wenche Merete Emblem; Fleurence, Joël; Roleda, Michael; Rustad, Turid; Slizyte, Rasa; Nordtvedt, Tom Ståle (Journal article; Peer reviewed, 2018-03-23)The effects of convective air-drying at 25, 40, and 70 °C and freeze-drying on the quality of the edible kelp Saccharina latissima to be used for food were investigated. Based on the analysis of the carbohydrate and amino ... -
Enrichment of the protein content of the macroalgae Saccharina latissima and Palmaria palmata
Aasen, Inga Marie; Sandbakken, Ingrid Schafroth; Toldnes, Bendik; Roleda, Michael; Slizyte, Rasa (Peer reviewed; Journal article, 2022)The large brown seaweeds (kelps) are potential sources of protein for animal feed. They have lower protein contents than most red and green algae, but due to potential for large-scale production, they may represent a ... -
In vitro evaluation of utilisable crude protein and methane production for a diet in which grass silage was replaced by different levels and fractions of extracted seaweed proteins
Ramin, Mohammad; Franco, Marcia; Roleda, Michael; Aasen, Inga Marie; Hetta, Mårten; Steinshamn, Håvard (Peer reviewed; Journal article, 2019)Utilisable crude protein (uCP), methane (CH4) production and other fermentation parameters were analysed in vitro for a diet in which grass silage was replaced by different levels of seaweed protein fractions prepared from ... -
Iodine content in bulk biomass of wild-harvested and cultivated edible seaweeds: Inherent variations determine species-specific daily allowable consumption
Roleda, Michael; Skjermo, Jorunn; Marfaing, Hélène; Jonsdottir, Rosa; Rebours, Celine; Gietl, Anna; Stengel, Dagmar; Nitschke, Udo (Journal article; Peer reviewed, 2018-07-18)This study represents a large-scale investigation into iodine contents in three commercially important and edible seaweed species from the North Atlantic: the brown algae Saccharina latissima and Alaria esculenta, and the ... -
Variations in polyphenol and heavy metal contents of wild-harvested and cultivated seaweed bulk biomass: Health risk assessment and implication for food applications
Roleda, Michael; Marfaing, Hélène; Desnica, Natasa; Jónsdóttir, Rósa; Skjermo, Jorunn; Rebours, Celine; Nitschke, Udo (Journal article; Peer reviewed, 2018-07-27)Seaweeds are increasingly used in European cuisines due to their nutritional value. Many algal constituents, such as polyphenols, are important antioxidants and thus considered beneficial to humans. However, many seaweed ...
