  • Low field nuclear magnetic resonance has gradually become the mainstream method for measuring solid fat content, which is an important index to qualify cocoa butter, margarine and other oils because it is simple, rapid and solvent free. However, Low field nuclear magnetic resonance direct method is a relative method, which requires the instrument to be calibrated using a glycerol trioleate/glycerol tristearate mixture. In this paper, the development and the principle of Low field NMR are introduced, the traceability and the stability of the glycerol trioleate/glycerol tristearate solid fat content reference material are studied, the measurement in different temperature are compared and the determination of the value was confirmed.
