Food Quality Analysis Applications

  • Microbial testing for personal care products sector

    The Problem: Microorganisms. personalcareMicrobiological contamination is a threat to product quality and process integrity in the personal care products and life sciences manufacturing industries – the purity of raw materials including water is essential to ensure manufacturing compliance. Microorganisms may be introduced at several stages of the process; subsequently, manufacturers must put in place stringent Quality Assurance / Quality Control (QA/QC) programs to manage microbiological contamination.

  • Chromatography systems for food industries

    Food samples exhibit a challenge to analytical chemists to determine pesticide residues to meet food safety regulations in USA and EU. Therefore, more careful sample preparation is needed to successfully identify and quantify these compounds in food. Dikma offers SPE columns with different absorbent phases and QuEChERS method for sample pre-treament.

  • 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.

  • Independent particle characterization services for dietary supplements

    Concurrent with the U.S. Food and Drug Administration’s final rule establishing regulations to require current good manufacturing practices (cGMPs) for dietary supplements, PTL can offer cGMP services to all supplement manufacturers. PTL has sustained its FDA registration since 1994, which involves rigorous inspections by FDA every 2 years or sooner. According to the final rule, proper controls must be in place for dietary supplements to be produced in a consistent manner for identity, purity, strength, and composition. PTL’s particle characterization tests can be conducted following FDA regulations. Valuable testing such as particle size and shape, image analysis, B.E.T. surface area, pore volume and pore size can be analyzed under cGMP compliance. These analyses can give insight into absorption, strength, and composition of the material being processed.

  • 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.

  • Chlorine Dioxide Water Treatment for the Food Processing Industry

    CleanOxide Chlorine Dioxide can safely be used for washing fruit and vegetables, seafood, meat, mushrooms and many other foodstuffs. CleanOxide Chlorine Dioxide destroys bacteria including potentially harmful pathogens such as E.coli, as well as controlling fungi and fungal spores ensuring reduced risk for the consumer and increased shelf life for the produce. Residual chlorine dioxide left on the produce degrades rapidly leaving no harmful residues.

  • Fragrance Fingerprinting

    Hiden gas analysis systems provide for high sensitivity, wide dynamic range, real-time analysis of almost any gas & vapour. Hiden’s application specific gas analysis systems are tailored to meet the specific application requirements, & include a range of special sampling, vacuum pumping & vacuum accessories. Hot zone sampling accessories are included for evolved gas analysis from furnaces, and thermo gravimetric analysers, TGA, for example. Thermal analysis methods are vital for catalysis characterization. For thermal analysis including TPD/TPO/TPR, studies, Hiden gas analysis systems include enhanced pumping for hydrogen and special close coupled sampling to the TPD/TPO/TPR reactor for optimum thermal analysis response. In Biogas applications the simultaneous analysis of H2S, CO2, water vapour and CH4 in the PPM to 100% concentration range provides vital information for process development and process monitoring.
