Analysis of ethylene oxide and 2-chloroethanol in food

Shimadzu Corporation
20 Dec 2023

In this application note by Shimadzu, the focus is on ethylene oxide (EtO/EO), a known toxic compound with carcinogenic and mutagenic properties. Despite these concerns, EtO has been extensively used in the food industry for fumigation due to its effectiveness in eliminating microbiological contamination. However, the compound undergoes reactions within food matrices, producing toxic by-products. The EU has phased out EtO use in food fumigation due to its toxicological risks, and has proposed maximum residual limits (MRLs) for EtO and its metabolite 2-chloroethanol (2-CE) in various food commodities. Recent recalls of non-compliant food products in the EU emphasize the need for quantifying EtO and 2-CE residues.

With the increase in demand for EtO detection worldwide, there is an increased need for greater laboratory capacity and relevant analysis methods to ensure food safety. In this note, Shimadzu introduces an analysis of EtO with QuEChERS and the GCMS-TQ8050 NX, which is equipped with the AOC-20i and AOC-20s for automation capabilities to meet the requirement for higher throughput and faster turnaround times.

MicrobiologyMicrobiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments.

This can reveal information on protein or gene expression, single nucleotide polymorphism (SNP), copy number variation (CNV), epigenetics and patient health in clinical diagnostic tests. Discover a range of microarray scanners and prefabricated antibody, protein, RNA and DNA microarrays for your analysis or consider creating your own custom microarrays with a microarray printer. Find the best microarray products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Automated Liquid HandlingAutomated liquid handling equipment is used to mix, dilute and dispense allotted volumes of liquid into microplates and other vessels automatically. The robotic, liquid handling arms can dispense from single channel to 3456 multichannel as well as operate nanoliter dispensing, enabling high throughput of samples. Find the best automated liquid handlers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Epigenetic AnalysisEpigenetic analysis products are used to study heritable phenotype changes that do not alter the DNA sequence, such as DNA modifications affecting gene activity. Determine whether genes have been methylated with DNA methylation quantification kits or methylation microarrays. Assess epigenetic regulation with histone modification kits or ChIP-on-chip microarrays. Kits are also available for bisulfite conversion and amplification of your samples, as well as epigenomic library preparation kits for next-generation sequencing (NGS).

Understanding bacterial genetics, growth, and metabolism is essential for developing antibiotics, vaccines, and improving industrial processes. Browse our peer-reviewed product directory to find the best bacterial research tools, compare products, check reviews, and get pricing directly from manufacturers.MutationMutations are changes in the DNA sequence that can lead to diseases, including cancer and genetic disorders. Analyzing mutations is crucial in diagnostics, drug development, and personalized medicine. Explore mutation detection tools in our peer-reviewed product directory; compare products, check reviews, and get pricing directly from manufacturers.ToxicityToxicity is defined as the degree to which a substance can harm humans or animals. It is essential to study the toxicity of pharmaceutical products during the development process so that optimum dosage can be established for the administration of the drug.Carcinogens
