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.


Applications of NMR to Food Science

Nuclear magnetic resonance (NMR) spectroscopy is one of the most common investigative techniques used by both chemists and biochemists to identify molecular structures as well as to study the progress of chemical reactions. Magnetic resonance imaging (MRI), another type of NMR technology, has extensively been used in medical radiology to obtain soft tissue images for diagnostic purposes in medicine. Food scientists have also explored the use of both NMR and MRI and continue to develop a wide range of applications for food NMR analyzer and food processing. This review begins with a brief introduction to NMR and then focuses on current diverse NMR applications in food research and manufacturing.

Topics covered include chemical compositional analysis and structural identification of functional components in foods, determination of composition and formulation of packaging materials, detection of food authentication, optimization of food processing parameters, and inspection of microbiological, physical and chemical quality of foods. This review also emphasizes the pros and cons of specific NMR application in the analysis of representative foods such as wine, cheese, fruits, vegetables, meat, fish, beverages (i.e. tomato juice and pulp, green tea, coffee) and edible oils, as well as discussing both the challenges and future opportunities in NMR applications in food science.

This report reviews the literature on the applications of NMR to food science from 1995 until March 2001. In order to be able to keep the number of references to manageable proportions, the number of papers referred to has been limited to those applications where NMR plays a major role in the experimental programme. Applications where NMR is simply used as a routine structural tool have been left out. Following an introductory section, the report covers water in foods, biopolymers, analysis and authentication, complex systems, and new methods for food analysis.
