Oracle

Process and laboratory staff in the food industry are increasingly pressed for time. The fat content of ever more samples must be determined fast and accurately.

Until recently, there was no reliable method to determine the fat content in different foods in less than 30 seconds.

One method is to use potentially hazardous wet chemicals but the results are available only hours later. Then there are the so-called fast methods such as NIR, FT-IR or NMR. They enable faster fat determination in food but, in practice, tend to be cumbersome.

Their downsides range from complicated, sample-dependent calibration to questionable results when the sample matrix is not known.

The solution: Easier and safer fat determination

CEM has vastly improved the NMR method, resulting in Oracle, the ultrafast fat analyzer for the food industry.

Oracle allows you to determine the fat content within 30 seconds even in unknown samples and without time-consuming method development or cumbersome calibration. Fat determination using Oracle does not require hazardous chemicals, so you’ll work safer than with wet chemical reference methods.

Measuring fat content according to ISO 16756

As a total fat analysis, ISO 16756 for fat determination by calibration-free NMR has been approved as a working draft method for the testing of milk and dairy products. This method represents a significant step towards greener, more sustainable laboratory analysis, with the added benefit of being a simple, reproducible method without the need for matrix-specific calibrations. The Oracle thus represents a reliable alternative to the hazardous/environmentally harmful extraction methods currently used as reference analytical techniques.

The Oracle technology complies with ISO 16756 / IDF 259

The Carr-Purcell-Meiboom-Gill pulse sequence, as described in ISO 16756/IDF 259, is an advanced TD-NMR technique capable of inducing a measurable response from lipid molecules. The ORACLE system is the only commercially available fat analyzer that utilizes this technology and provides the accuracy of the reference extraction method in less than one minute without matrix-specific calibrations or solvents
