Researchers added tiny chitosan nanoparticles made from mushrooms and marine sources to palm oil used in cooking and frying. They found that mushroom-based chitosan nanoparticles improved the oil’s ability to conduct heat better than marine-sourced alternatives. This enhancement could make cooking faster and more efficient while reducing harmful compounds formed during high-temperature cooking. The oil treated with chitosan nanoparticles maintains good quality and remains safe for food use.
