Abstract

Background: This study introduces a phase-transfer headspace strategy to establish an efficient and innovative method for quantifying potassium bromate in flour. The method involves detecting carbon dioxide produced from the gas-producing reaction of potassium bromate in flour with oxalate. The carbon dioxide produced is quantitatively analyzed using gas chromatography (GC) in a sealed vial.

Results: The study showed that the new technique was very precise (relative standard deviation ≤3.18%) and accurate (relative differences ≤5.37%) for potassium bromate quantification, with low detection limits (limit of detection = 1.83 mg kg^-1) and good recovery rates (98.07% to 102.37%).

Conclusion: The proposed phase-transfer headspace strategy offers a fast and simple method for the regular estimation of potassium bromate in flour, providing a valuable tool to ensure the safety and effectiveness of flour-related products. It can be implemented in a wide variety of contexts from manufacturing to quality control. © 2025 Society of Chemical Industry.

期刊介绍： The Journal of the Science of Food and Agriculture publishes peer-reviewed original research, reviews, mini-reviews, perspectives and spotlights in these areas, with particular emphasis on interdisciplinary studies at the agriculture/ food interface. Published for SCI by John Wiley & Sons Ltd. SCI (Society of Chemical Industry) is a unique international forum where science meets business on independent, impartial ground. Anyone can join and current Members include consumers, business people, environmentalists, industrialists, farmers, and researchers. The Society offers a chance to share information between sectors as diverse as food and agriculture, pharmaceuticals, biotechnology, materials, chemicals, environmental science and safety. As well as organising educational events, SCI awards a number of prestigious honours and scholarships each year, publishes peer-reviewed journals, and provides Members with news from their sectors in the respected magazine, Chemistry & Industry . Originally established in London in 1881 and in New York in 1894, SCI is a registered charity with Members in over 70 countries.
