Effect of electron beam irradiation on quality indicators of peanut butter over a storage period

► Peanut butter was exposed to a range of electron beam doses. ► Quality indicators were monitored over a 14-day storage period. ► Colour, spreadability, peroxide values, and TBARS were monitored. ► SDS-PAGE, fatty acid and amino acid profile were measured as a function of dose. ► Electron beam irradiation caused significant changes in peanut butter.
