Oils and fats are recognized as essential nutrients of our daily diet and contribute significantly to the regulation of different body functions. Numerous parameters are used to assess their quality. Dedicated spectroscopy solutions enable a rapid analysis of edible oils and fats.
Edible oil producers and food processors are seeking fast and non-destructive way to analyze fats and oils for process and quality control purposes. Different parameters are used to assess the quality of edible fats and oils, including iodine value (IV), free fatty acids (FFA), trans fatty acids (TFA), anisidine value (AV), and various other parameters
Rapid quality control for edible oils can be achieved by FT-NIR solutions. The analysis is quick, cost-effective and safe to use, even for untrained staff, since no sample preparation is required. The oil is simply filled into an 8mm glass vial and measured in the sample compartment of the spectrometer.
X-ray fluorescence (XRF) enables fast and nondestructive elemental analysis of process indicators such as phosphorus and chlorine in edible oils. Bruker’s Elemental Analyzer portfolio includes high-throughput lab-based ED-XRF and WD-XRF, point-and-shoot handheld XRF, micro-XRF, and ultra-trace analysis TXRF spectrometers. Energy-dispersive spectrometers with polarized X-ray optics are particularly suitable for the analysis of trace level elemental concentrations in oil and similar (light) matrices.
Solid Fat Content (SFC) determination is a recognized international standard method of prime importance for food processing and development. The SFC determination is used to measure the melting profile of fat composition, ensuring proper performance of several final products, such as margarine and cocoa butter.
Rancidity of edible oil is a major problem in food related industries. It occurs during storage and is caused by free radical oxidation of unsaturated fatty acids, resulting in foul odors and tastes in the final product. Bruker’s compact, yet fully automated electron spin resonance (ESR) system was specifically designed for measuring free radical oxidation and shelf life in food products. It will determine oxidative resistance in as little as 30 minutes measuring the free radicals instead of end products.
The portable Counter Top XRF (CTX) is small, light-weight, safety-interlocked, and battery operated. At 7 kilograms in weight, the self-contained CTX is truly portable, and has a small footprint of only 14 cm in width. Up to 48 elements analyzed per calibration.
The Scion 6000 Series HPLC aims for confidence in results through outstanding life-time performance. A robust design maximizes uptime and productivity levels whilst minimizes cost of operation.
Stylish, smart, and functional, featuring intuitive touch screen technology, the new RX-i series makes navigation and selection a breeze. The RX-i series come with newly added functions, such as USB flash drive and self-diagnosis capability.
The PRM series measures the Refractive Index, Brix, concentration/water content, mixing ratio, etc. of various solutions with high accuracy.
Whether for the industrial researcher, quality control, or academic institutions, the microESR allows users to detect the concentration and composition of free radicals with a simple software interface and easy-to-follow workflows.
