Sunlight‐Induced Lipid Oxidation and Degradation of Edible Oil Mediated by Hemoglobin: Implications for Food System Sustainability [PDF]
Food Sci NutrSunlight‐activated hemoglobin (Hb) functions as a robust natural biocatalyst that promotes the degradation of edible oils through a dual, synergistic pathway. Photo‐excitation of Hb triggers simultaneous energy transfer, generating singlet oxygen (1O2) and electron transfer, forming highly reactive ferryl (HbFe(IV)═O) species.
