Introduction

Ethylene oxide (EO) is sometimes used as a fumigant on food products to control pests and insects during storage and transportation. However, residue of EO might remain in the products, raising concerns about the potential health risks associated with it. Therefore, it is essential to monitor and analyze ethylene oxide levels in food product to ensure compliance with safety regulations and protect consumer health. In this study, both ethylene oxide (EO) and 2-chloroethanol (2-CE) in rice were analyzed. 2-CE, a potential byproduct of EO fumigation, is also a compound of interest due to its toxicity and potential health implications. By utilising dynamic headspace and GC-MS/MS, precise and sensitive detection of both EO and 2-CE residues in rice samples can be achieved. The limit of quantitation is 5 ng/g with area %RSD (n=5) for EO and 2-CE at 5.6 % and 4.9 %, respectively. The spike recovery study at concentrations of 10 ng/g, 25 ng/g and 100 ng/g yielded recoveries within 70 %-130 %. This comprehensive analytical approach enables accurate quantification and identification of these compounds, significantly contributing to the overall safety and quality assurance of the food supply chain.
