Biogenic amines in krill meal: Liquid chromatographic determination with post-column derivatization and fluorescence detection
Hovde, Gunnhild; Wang-Andersen, Jarle; Asbjørnsen, Bente (Research report, 2015)Biogenic amines are formed by microbial decarboxylation of amino acids and represent a considerable toxicological risk in some food products. This method is intended for quantification of histamine, cadaverine and putrescine ... -
Histamine in fish: Liquid chromatographic determination with post-column derivatization and fluorescence detection
Hovde, Gunnhild; Wang-Andersen, Jarle; Asbjørnsen, Bente (Research report, 2015)Histamine is formed by microbial decarboxylation of histidine. Histidine is an essential amino acid which is present in all fish and especially in fish tissues of Scomberiscida and Scombridae families, for example mackerel, ... -
Validation of a method for analysis of soluble phosphorus by use of alkaline extraction and spectrophotometric determination
Hovde, Gunnhild (Research report, 2013)The aim of this project is to validate Nofima BioLab’s method for analysis of soluble phosphorus. The definition of soluble phosphorus in this context is phosphorus that is not bound in bone material. Validating a method ... -
