To establish a standard method for determing solid fat content, the NMR method was tested at six laboratories and the results were examined for collaboration.
Two types of instruments, pulse NMR and wide-line NMR were used.
Standard deviation in results at six laboratories was less than 1.5 for the step wise method, but more than 1.5 for the rapid method. The standard deviation in results at a single laboratory was much less than either of these cases.
No significant difference could be observed in the values obtained using both instruments.
Solid fat content values measured for a mixture of fully hydrogenated rapeseed and rapeseed oil agreed well with the percentage of solid by weight.
