Comparison of the direct and indirect wide‐line nuclear magnetic resonance methods for determining solid fat content

Abstract

Abstract A direct method of measuring the solid fat content by wide‐line nuclear magnetic resonance (NMR) was compared with the conventional indirect wide‐line NMR procedure. The direct method is based on the use of variable gate widths available on the Newport Analyser Mk IIIA. The results obtained for four different fats using the direct method did not differ significantly from those of the indirect method. As the direct method required additional measurements, was somewhat more complex theoretically and gave more variable results because of the weaker signal obtained at the wide gate, no real advantage could be found for its use.
