A Practical Use Of Electronic Noses: Quality Estimation Of COD Fillet Bought Over The Counter

An electronic nose is described which has been used for quality estimations of cod fillet bought "fresh" over the counter. The electronic nose was trained to predict the age of initially fresh reference fillets. 'The trained electronic nose was then used to predict the age of now cod fillets, bought five days later. The predictions for these samples were within a certain interval [33.3 hours - 47.3 hours]. These values clearly show that the test material was considerably older when bought than the reference material.
