Classification of fresh Atlantic salmon (Salmo salar L.) fillets stored under different atmospheres by hyperspectral imaging

► Investigating spectroscopic changes in salmon stored under different atmospheres. ► Potential of hyperspectral imaging for classification of fillets by packaging. ► Spectral development during storage was dependent on packaging. ► Spectral variations at 606 and 636 nm essential for successful classification. ► Packaging-dependent spectral changes possibly related to the oxidation of haem.
