Rapid NMR fat analyzer
The ORACLE Rapid NMR Fat Analyzer enables fast and accurate fat analysis in food, dairy, and animal feed samples. Using advanced time-domain nuclear magnetic resonance (TD-NMR) technology, the system provides reference chemistry accuracy without the need for method development, matrix-specific calibrations, or solvents.
The ORACLE delivers fat analysis results in approximately 30 seconds and can analyze samples with fat contents ranging from 0.02% to 100.00%. It’s also possible to combine the system with the SMART 6 Analyzer for combined moisture/solids and fat analysis in less than five minutes.
How does the ORACLE achieve rapid and accurate fat analysis?
The ORACLE uses specialized TD-NMR technology based on the Carr-Purcell-Meiboom-Gill (CPMG) pulse sequence described in ISO 16756 and IDF 259. This technique enables the system to detect the proton signal from fat molecules while separating it from signals generated by other components, including proteins, carbohydrates, and ash.
By isolating the fat signal, the ORACLE can provide direct total fat measurement without requiring sample-specific calibration methods. This makes universal fat analysis possible across different sample matrices and compositions.
The technology provides reference extraction method accuracy without the need for traditional solvent-based extraction procedures such as Mojonnier, Weibull-Berntrop, and Rose-Gottlieb methods.
Simple workflow without method development
Unlike alternative rapid fat analysis techniques that may require extensive calibration development, the ORACLE does not require method development before analysis. The system is suitable to analyze different food sample types directly, reducing variability caused by different sample matrices and user-to-user differences.
Operation is straightforward: the user places the sample in the system and starts the analysis. The ORACLE then determines the fat content and provides an accurate and precise result in approximately 30 seconds.
For laboratories requiring higher throughput, the ORACLE can be paired with a robot for unattended analysis of up to 100 samples per batch.
Validation and standards
The ORACLE technology meets ISO 16756 and IDF 259 requirements and has been validated through various AOAC methods, including:
- AOAC Official Method 2008.06: Moisture and Fat in Meats.
- AOAC PVM 1:2004: Moisture/Solids and Fat in Dairy Products.
Results from ORACLE analysis have shown a high correlation with certified reference material (CRM) results across a wide range of sample types and fat concentrations.
What is ISO 16756?
ISO 16756 is an international standard that provides guidance on determining the total fat content in milk and milk-based products. It utilizes low-resolution nuclear magnetic resonance (NMR) spectroscopy with the Carr-Purcell-Meiboom-Gill (CPMG) pulse sequence to optimize the specific response of fat molecules.
This standard is applicable to a wide range of dairy products, including milk, cream, yogurt, ice cream, processed dairy, cheese, and dairy powders. It can analyze any milk and milk-based products, regardless of their source (species or region). The method is suitable for dry samples (with moisture content ≤ 10%) and liquid or wet samples that have been pre-dried to remove all appreciable water. Additionally, the application is not limited by sample viscosity, color, or particle size. View the standard here.
Combined moisture, solids, and fat analysis with SMART 6
The ORACLE can be combined with the SMART 6 Moisture & Solids Analyzer to measure moisture/solids and fat within a single workflow.
The SMART 6 uses dual-frequency energy to analyze moisture and solids in wet or dry products in approximately three minutes. It includes a pre-programmed library of optimized drying methods for use with the ORACLE. Together, the SMART 6 and ORACLE provide moisture/solids and fat results in less than five minutes.
Applications
You can use the ORACLE for fat analysis in a wide range of food, dairy, and animal feed products, including:
Meat and fish: beef, chicken, cod, duck, lam, pork, salmon, turkey, venison
Dairy products: butter, cheese, cream (heavy), egg whites, formula (infant), ice cream mix, milk, sour cream, yoghurt
Processed foods:Â chips, crackers, coffee creamer, cookies, dog food, dough, dressings, mayonnaise, noodles, nutritional drinks
Powders:Â cheese, coffee creamer, dairy, formula (infant), gravy, milk, non-dairy, wheat flour, whey
“We have been using the ORACLE and SMART 6 over the last year to measure fat, solids and moisture content with great success and ease.”
