Validation of Universal Fat Analysis Method using Certified Reference Materials

Introduction

The ORACLE universal fat analyzer is a low-resolution, timedomain NMR instrument (TD-NMR). However, unlike other TD-NMR instruments that rely on free induction decay (FID) or spin echo pulse sequences, the ORACLE uses a proprietary train of pulses, which not only provides sufficient resolution to separate the fat signal from the signal of other components, but it also normalizes fat response, so that any fat molecule, regardless of source, results in a uniform signal. Because of these two properties, the ORACLE is able to accurately measure fat content in any food sample with no calibration or method development.

As part of the ORACLE validation process, nearly 40 different certified reference materials (CRMs) were gathered and analyzed on the ORACLE.
