FTIR spectra of beef fat and lard are difficult to be differentiated,
however, due to the capability of FTIR spectra as fingerprint tools,
both spectra revealed bit differences in peak/shoulder intensities and
the exact wave numbers at which the maximum absorbance was observed
for each fat and oil, due to the different nature and composition
of the both lard and beef fat, especially at wave number regions of 3007
(a), 1117 (l) and 1098 cm−1 (m)
