Chemometric Fat Analysis by 1H and 13C NMR
A series of Trans Fat standards was purchased from AOCS. The ability of 1H and 13C NMR to predict Trans Fat Content as well as Saturated, Poly-unsatured, and Mono-unsaturated Fat Content.
The data of the samples is presented in the table below:
PLS regression techniques were used to correlate 1H and 13C NMR spectral variations to the unsaturation level and type of unsaturation of the samples.
Processed 13C data is shown below:
1H NMR data is shown below:
The following correlations were obtained from the 13C NMR data.
