    Gas analysis & monitoring systems for food traceability

    Recognition of raw materials: The analysis of stable isotopes is very important especially in studies of authenticity of the food. It, on the basis of different isotopic ratio, allows to recognize molecules, present in foods, having the same chemical structure but coming from different raw materials or processed by different processes, for example for biological synthesis or industrial.

  • Reduced Fat Interference with Analysis of Pesticides in Avocados

    QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) is a very popular method for the extraction and cleanup of fruit and vegetable samples for pesticide residue analysis.2-4 The extraction step uses acetonitrile and a salting out effect (with MgSO4). Cleanup is then accomplished using dispersive SPE (dSPE) followed by a centrifuge step prior to analysis. This application shows the clean-up and analysis using Supel™ QuE Z-Sep+ QuEChERS and an SLB®-5ms GC column.

  • Analysis of Pesticides in Beef Kidney

    The suitability of the new cleanup sorbent, Supel QuE Z-Sep+, has been successfully demonstrated for cleanup of beef kidney matrix. It was found to effectively reduce background without significantly reducing recovery of lipophilic pesticides such as organochlorines and some pyrethroids. GC-MS full-scan data indicated Z-Sep+ was found to provide better cleanup in the form of reduced background than PSA/C18, and less interference in the GC-MS/SIM analysis of the target pesticides themselves.

    Determination of heavy metals in food

    This analytical procedure is intended for measuring the content of the elements (cadmium, lead, arsenic, tin, chromium and mercury) in the samples of food products by atomic absorption spectrometry with electrothermal atomization using an “MGA-915M” Graphite Furnace AA Spectrometer.

    The method is based on measuring resonance radiation absorption that occurs when the radiation passes through a layer of atomic vapor in the electrically heated graphite furnace of the “MGA-915M” AA spectrometer. The concentration of the elements is determined from the integrated analytical signal and is calculated using a preset calibration graph. The samples of food products are digested prior to analysis in accordance with standard methods.

  • Increased Pigment Removal with Analysis of Pesticides in Oranges

    An application was developed to demonstrate increased pigment removal for the analysis of pesticides, using Supel™ QuE Z-Sep/C18 QuEChERS and an Ascentis® Express C18 HPLC Column. The improved cleanup can decrease column and instrument fouling, leading to extended LC column lifetime and reduced instrument downtime.

  • Analysis of Methylimidazoles in Caramel Colored Carbonated Beverages

    Caramel colorings are used as additives in a broad range of food and beverage products to impart a desired color, but have no nutritional or preservative function. Recently, the potential hazard to humans of ammonia- and ammonia-sulfite-process caramel colorings was raised, because they contain the by-product 4-methylimidazole, which is a potential carcinogen.1 The methylimidazole compounds are difficult to analyze due to their polar nature and low molecular weight. Traditional reversed phase techniques are unsuccessful in retaining these small polar compounds. Therefore, most HPLC methods utilize ion-exchange resins for analysis. Another common method involves GC analysis after the analytes first undergo a derivatization step. The purpose of the work shown in this article was to develop a simple and fast analytical method to determine the levels of 2-methylimidazole and 4-methylimidazole in caramel colored carbonated beverages.

  • A New GC-MS Method for Mycotoxin Analysis Using 13C-marked Mycotoxin Derivatives

    Andreas Breidbach [1] and Wolfgang Brodacz [2,3,4] developed a new GC-MS method using fully 13C isotopelabelled analogues of T-2 toxin and HT-2 toxin that allows for the detection of these toxins at concentrations as low as 2–5 ppb.

    Determination of D- and L-isomers of tartaric and malic acids in wines, wine materials, and food additive

    Naturally occurred is predominantly L-form of tartaric acid whereas its D-form and the relevant racemic mixture can be artificially synthesized. Generally, artificial acidification of wine with tartaric acid is allowed by OIV, but only pure L-form must be used for this purpose. Thus the analysis of tartaric acid isomers either in food additives or directly in wine can be an important parameter in clarifying any deviations in wine production. Analysis of isomers of malic acid is also within the necessary oenological procedures stated in OIV recommendations. LUMEX INSTRUMENTS offers the present method which allows determination of L- and D-forms of tartaric and malic acids in wine, wine materials, and special food additives by capillary electrophoresis method.
