New Method to Reduce Mercury Levels in Tuna Promises Safer Fish Consumption
In a groundbreaking study from Swedish University of Agricultural Sciences and Chalmers University of Technology, scientists have unveiled a promising method to reduce mercury levels in tuna by up to 35 percent, a breakthrough that could significantly enhance food safety. This new approach involves the incorporation of cysteine, a naturally occurring amino acid, into the packaging process of canned tuna.
Mercury contamination in fish has long been a concern, particularly for individuals such as pregnant women and young children, who are advised to limit their intake of high-mercury fish. This new method leverages the chemical affinity between mercury and cysteine. Cysteine is a natural candidate for capturing mercury, as shown by prior research where its strong binding properties were evident.
