Determination of prior treatment of fish and fish products using microwavedielectric spectra

Microwave dielectric spectra of fish products [processed prawns (Pandalus b orealis), cod (Gadus morhua), haddock (Melanogrammus aeglefinus) and saithe (Pollachus virens)] were transformed using the statistical method of princ ipal component analysis. The principal components obtained were used as des criptors to construct discriminant functions for the separation of the samp les into groups, e.g. added water or no added water, polyphosphate or no po lyphosphate. The method was validated using internal cross-validation.
