Differentiation between Normal and White Striped Turkey Breasts byVisible/Near Infrared Spectroscopy and Multivariate DataAnalysis

摘要

The appearance of white striations over breast meat is an emerging and growingproblem. The main purpose of this study was to employ the reflectance ofvisible-near infrared (VIS/NIR) spectroscopy to differentiate between normal andwhite striped turkey breasts. Accordingly, 34 turkey breast fillets wereselected representing a different level of white striping (WS) defects (normal,moderate and severe). The findings of VIS/NIR were analyzed by principalcomponent (PC1) analysis (PCA). It was found that the first PC1 for VIS, NIR andVIS/NIR region explained 98%, 97%, and 96% of the total variation, respectively.PCA showed high performance to differentiate normal meat from abnormal meat(moderate and severe WS). In conclusion, the results of this research showedthat VIS/NIR spectroscopy was satisfactory to differentiate normal from severeWS turkey fillets by using several quality traits.
