Hong Kong Legislative Proposals on Regulations of Edible Fats and Oils and Recycling of "Waste Cooking Oils" July 2015

Challenge of Testing "Gutter Oil"

“Gutter oil”, “Tainted oil” and “Substandard oil” are generic terms without scientific definition for the problem edible fats and oils. Currently , there is no universal testing standard internationally, but only by identifying harmful substances such as Benzo[a]pyrene as reference indicators. In other words, the “substandard oil” may be able to meet with individual harmful substances standards.


In 2015, Food Safety Research Center of the Hong Kong Polytechnic University published a rapid screening method using MALDI-MS to distinguish gutter oils. This method is able to identify the composition of a mixed oil, hence distinguish mislabel fats and oils within several minutes, mixing and mislabelling are the two common characteristics of "gutter oils".


While testing methods are being developed, edible fats and oils is safe guard by proper regulations, self-discipline, education and publicity.

Dr. Leung Ka Shing, Visiting Associate Professor of ABCT Dept., PolyU concluded in the public forum "Gutter Oil: Technical, Trade, Heath and Regulatory Perspectives" on 4th October, 2014 that establish traceability and control mechanism are the most important actions.
