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:
Process NMR Analytical Data on Edible Oils
 
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:
Processed C NMR Data
 
1H NMR data is shown below:
Processed H NMR Data
 
The following correlations were obtained from the 13C NMR data.
