Physical activities are associated with increased production of reactive oxygen species. The production of reactive oxygen species is dependent of the intensity, duration and type of activity. Although the physiological amounts of reactive oxygen species are necessary to regulate cell reactions, their excessive production can cause numerous damages to the structure and function of cells and wea...
European eel proteins hydrolysates (EPHs) were produced from A. anguilla muscle protein and isolate using Purafect®, goby crude proteases B. invictae proteases. EPHs had high contents displayed diverse molecular mass distributions. Muscle (MPHs) (PIHs) obtained both by Purafect® the highest antibacterial activity. PIHs emulsifying stability. MPHs higher chelating effects. ability to prevent ble...
