4. Conclusion
This study has shown the ability of DSC coupled with PCA in
discriminating LD adulteration even at low mixed dose of less than
0.5%. Therefore, the crystallisation and melting profiles provided
clear evidence on the cross-contamination caused in between
BF–LD and CF–LD. According to Saadi et al. (2012a) the cooling
curves are more interpretable, whereas the melting profiles ismore complex due to the TAGs melting kinetics and their transition
protocols. This study also followed similar trends, where cooling
thermograms provides better definition of different animal
profiles adulterated with LD.
