Evaluation of the Mitigating Capacity of Antioxidant Extracts on the Formation of Acrylamide and HMF in Starchy Food MatricesHeating starch-rich foods at high temperatures (100-250 °C) promotes the formation of Maillard reaction products (MRPs), which can generate both positive sensory attributes and harmful compounds, including neoformed contaminants (NFCs) such as acrylamide (AA) and hydroxymethylfurfural (HMF), which are associated with health risks.To mitigate the formation of these harmful compounds for human health, it is proposed to use natural antioxidants, especially polyphenols, from extracts of Chilean sources such as Durvillaea incurvata and Ugni molinae. The objective is to simultaneously reduce the formation of AA and HMF in starchy foods like potato chips and crackers, while preserving sensory attributes and improving antioxidant capacity.The project includes obtaining optimized extracts through ultrasound-assisted extraction (USAE) and evaluating their effectiveness in final products, aiming to develop sustainable and scalable strategies to enhance food safety without compromising quality.
