Geographic Origin

Food and beverage producers, in response to increasing food fraud, are seeking to verify the geographic origin of raw materials and finished products.

For example, the quality and price of wine is partly determined by the source of the grapes used to produce it, and the traceability of the wine origin is important for brand protection. Elemental profiling using our ICP-MS systems and related statistical software correlates the levels of trace metals in wines to the soil , which can be used to differentiate their geographical origin.

Similar analyses conducted on other high level goods, such as olive oils, may confirm their geographic origin.

Adulteration

Adulteration has been around for thousands of years, however the 2007 melamine crisis in China was the first widely reported incidence of animals and babies falling ill en masse. To help protect consumers around the globe, we are arming food companies and processors with the tools to detect and prevent this threat.

For example:

  • Adulterant screen software on our FT-IR and FT- NIR systems enables you to perform – in one minute or less -- pass/ fail screening for adulterants, with no sample preparation and minimal scientific background required.
  • Our milk powder analyzer applies advanced algorithms to screen for both known and unknown adulterants. It also performs the same fast nutritional parameter measurements routinely used for protein, moisture and fat.
  • Our GC/MS solution measures melamine down to regulated limits as defined by multiple international regulatory bodies.

These are just a few examples of the innovative technologies offered by PerkinElmer that help researchers to identify intentional ingredient substitutions in food products to protect the world’s supply chain.

    Augmenting Standard Methods of Measuring Airborne PM2.5 Using IR Imaging

    The use of IR imaging expands the measurement possibilities by giving information about the individual types of materials present in the collected particles. The information from the IR imaging experiment is not only qualitative (i.e. identification of the particulates), but can also be calibrated to give quantitative information on the components present. The IR imaging measurement will take only five minutes, whereas Ion Chromatography requires solvent extraction of the particulates and would take around 20-25 minutes per sample

    A novel method (TG-IR) for the rapid determination of Total Petroleum Hydrocarbons (TPH) in soil

    A gas chromatographic analysis of the extract can provide even greater sensitivity and more detailed compositional information, but further increases the time required for the analysis. Thermogravimetric analysis coupled to infrared spectroscopy (TG-IR) can provide detailed information about the amount and nature of the pollution, while requiring no sample preparation at all. This application note illustrates the kind of data that can be obtained with a modern TG-IR system.

    Biodiesel Concentration Measurements Using Attenuated Total Reflectance (ATR)

    Biodiesel fuels are often blended compositions of diesel fuel and esterified soybean oils, rapeseed oils, or other potential vegetable oils as well as fats. The physical and combustion properties of these biofuels have allowed them to achieve similar performance to diesel fuel. However, there are several characteristics that are of concern. These differences, especially the cetane reduction, require that adequate control of the biofuel concentration be implemented.

    Discrimination of Herbal Lifestyle Products Using AssureID SIMCA and COMPARE Algorithms

    Herbal lifestyle products are widely used as alternatives to medicines around the world, with as many as 80% of people using them as a primary source of healthcare in developing countries. These treatments are commonly regarded by scientific papers, and on some occasions the media, as being inferior to orthodox treatment. This is due to the variation between herbal formulations which will not be present in so called ‘single-chemical’ drugs. The reasons for the aforementioned variation involve several factors including storage, environmental conditions, handling and unintentional or intentional contamination (adulteration).

    Cavity-enhanced Absorption Spectroscopy for Trace Gas Detection with Frontier

    Cavity-enhanced absorption spectroscopy (CEAS) has similarities with the better known cavity ringdown technique (CRDS) which measures the signal decay as a laser pulse emerges through one of the mirrors after successive reflections. By measuring the increase in the rate of decay caused by an absorbing species, CRDS can measure ppb concentrations of small molecules. The ringdown technique has typically been applied to small molecules where the wavelength of a NIR laser source can be tuned across very narrow individual lines of the spectra. In contrast this report describes CEAS using a broadband source applied to larger molecules where the spectra are broader.

    Determination of Benzene in Gasoline by ASTM D6277 with Spectrum Two

    IR spectroscopy is an ideal method for quantifying benzene at the concentration levels required, and there are several standard methods for this measurement, all of which utilize the distinctive C–H out-of-plane deformation band at around 673 cm-1. While this band is characteristic of benzene, toluene and xylenes have some weak absorption at this frequency that can interfere with the results if high concentrations are present.

    Diamond ATR and Calibration Transfer for Biodiesel-Blend Analysis by ASTM D7371

    Biodiesel is seldom used neat (B100), typically being blended with fossil diesel at ratios from 5% v/v (B5) to 30% v/v (B30). Verifying the FAME content of diesel-fuel blends is an important aspect of quality control and auditing of blending and distribution operations. Because FAME has a strong infrared absorption at 1745 cm-1 due to the ester carbonyl group, infrared spectroscopy is an excellent technique for this analysis, and there are EN and ASTM® standard test methods describing the procedure

    A Comparison of Standard Test Methods for Determining FAME in Diesel by Infrared Spectroscopy

    As the importance of sustainable energy production increases, so too does the global commitment to using fuels from renewable biological sources. Biodiesel is one such renewable fuel. Consisting of fatty acids of methyl esters (FAME), it is produced from plant crops by transesterification – a reaction in which natural triglycerides are cleaved and reacted with methanol, producing glycerol and FAME. Rapeseed, soy, sunflower, palm and jatropha are just part of the range of feedstocks used globally in the production of biodiesel.
