Mercury content in tuna can be reduced with new packaging solution
Fish is a high-quality source of protein, containing omega-3 fatty acids and many other beneficial nutrients. However, the accumulation of toxic mercury also makes fish consumption a concern, of which tuna is particularly susceptible. Researchers have now come up with a novel approach to packaging canned tuna infused in the water-based solution of amino acid cysteine. It was shown to remove up to 35 percent of the accumulated mercury in canned tuna, significantly reducing human exposure to mercury via food.
