Solid Fat Content NMR Measurement

Solid Fat Content is the percentage of solids in fat at specified temperatures. Solid Fat Content (SFC) is an important characteristic that can influence appearance, flavor release, melt rate, shelf life and stability of fat based food products. In the chocolate industry it is desirable to manufacture products with the ideal Solid Fat Content that will allow for chocolate to remain solid at room temperature, but still give consumers that “melt in your mouth” experience. Knowing various characteristics of your product from solid fat content allows you to direct your manufacturing processes in a way that achieves the highest quality products.

The measurement of solid fat content (SFC) within the baking, confectionary and margarine industries is crucial as fats are a key component in many processed foodstuffs produced within these industries. Fats are complex ingredients which play a key role in nutrition and consumer appeal of products. Measurement of solid fat content (SFC) is the industry standard approach to understanding the melting behaviour of edible oils and fats. The reason this is so important is that the melting profile of fats is one of the parameters which must be carefully controlled to ensure consistent products.

Solid Fat Content (SFC) determination is of prime importance for food processing and development.
Raw materials like fat compositions or blends need to be characterized and controlled according to their melting profiles. The SFC determination by time domain (TD) NMR analysis is the internationally recognized standard method. In a close partnership with the oil & fat industry spanning more than 4 decades we has developed its dedicated SFC Analyzer. All types of SFC methods are supported by the PQ001,including direct/indirect and parallel/serial methods.
The TD-NMR analysis provides a quick, non-destructive and solvent-free measurement. We also offers a fully automated solution including tempering procedures,NMR analyzer measurement, and determination of the SFC value plus presentation of the melting curve.
Solid Fat Content analysis is important for food manufacturers that produce fat based food products. Dynalene provides reliable solid fat content analysis with a quick turnaround time. With our top of the line DSC, Dynalene has the ability to test your fat based foods.


NMR Solid Fat Content Analyzer

The determination of solid fat content (SFC) by NMR analysis is recognized by the international standards. Niumag has been dedicated to research and develop NMR PQ001 SFC Analyzer which offers the determination of SFC values and presentation of the melting curve with non-destructive, fast and accurate measurements.

Solid Fat Content (SFC) is generally accepted analysis of fats and oils in the food industry. The traditional extraction methods for SFC determination are slow, irreproducible and require additional chemicals. Direct measurements of SFC by NMR (nuclear magnetic resonance) provides quick and accurate determination of SFC value. NMR as method of fats and oils analysis is included in the following international standards:

  • AOCS Cd 16b-93 revised in 2000 (in USA)
  • ISO 8292 (in Europe)

Solid Fat Content determination by benchtop NMR is based on direct ratio measuring between the solid and liquid parts of the sample.


The PQ001 SFC NMR Analyzer was launched in 2008. After years of upgrading, PQ001 has many advantages such as small size, high precision, good repeatability, good stability and excellent cost/benefit performance. Based on these advantages, PQ001 has been widely used in the determination of Solid Fat Content.
