Color changes in peanut butter resulting from electron beamand
gamma irradiationwere reported reported that
gamma irradiation in excess of 3 kGy decreased the L* value of peanut
butter. And reported that during electron beam
radiation color changes of peanut butter occurred. L, a, and b values of
microwave-treated samples were not significantly different from
those of non-treated samples (Table 2). L values decreased as microwave power increased from 0 (non-treated sample) to 6 kW,
but these differences were not significant (P > 0.05).
reported that there were no significant color changes during
pasteurization of peanut butter crackers by RF treatment.
