The inhibitory effects of cold plasma-activated water (PAW) on the formation of AGEs and methylimidazoles in cookies was examined. The results showed that different PAW (parameters: 50 W–50 s, 50 W–100 s, 50 W–150 s, 100 W–50 s, 100 W–100 s, and 100 W–150 s) reduced the contents of AGEs and methylimidazoles, in which the maximum inhibition rates were 47.38% and 40.17% for free and bound AGEs and 44.16% and 40.31% for free and bound methylimidazoles, respectively. Moreover, the mechanisms associated with the elimination of carbonyl intermediates and free radicals was determined by electron paramagnetic resonance (EPR) and high performance liquid chromatography-ultraviolet/visible absorption detector (HPLC-UV/Vis). The results showed the quenching of total free radicals, alkyl free radicals, and HO· by PAW, leading to the suppression of glyoxal and methylglyoxal intermediates. These findings support PAW as a promising agent to enhance the safety of cookies. • PAW pretreatment reduced AGEs and methylimidazole formation. • The peak inhibition rates for AGEs and methylimidazoles by PAW were 47.38 and 44.16%. • Generation of intermediates was mitigated by PAW pretreatment. • PAW pretreatment reduced the total levels of free radicals.
