A new research recently published in the scientific journal Food Bioscience includes the THz time-domain spectroscopy results of the bovine bone powder. The optical properties were measured in THz range for adult cows’ femur and tibia bones from the same breed and in the age range from 93 to 120 months. The spectral data were analyzed using principal component analysis and agglomerative hierarchical clustering techniques.
Results of the study showed that the anatomy of the bones was more significant rather than the age. Interestingly, refractive index increased with age of the cattle and was
higher for femur bone if comped to tibia bone.
The work was accomplished in collaboration with Pontificia Universidad Católica de Chile, Millennium Institute for Research in Optics (Chile) and INRAE – Centre Clermont-Auvergne-Rhône-Alpes (France)
