High temperature food processing has many advantages; however, toxic compounds such as furans and acrylamide (by-products of Maillard reaction) can be formed. Acrylamide is classified as a probable human carcinogenic by the International Agency for Research on Cancer (IARC), which generates many investigations to mitigate its formation in food. This work aimed to evaluate the influence of Inca Muña (Clinopodium bolivianum) polyphenols on acrylamide mitigation in the process of obtaining potato chips. The leaves of Inca Muña obtained 91,0 ± 0.3 mg AGE/g bs of phenolic compounds and 1 003,7 ± 68,0 µmol TE/g bs of antioxidant capacity. The extract was partially purified by adsorption chromatography and lyophilised (EPPL). Acrylamide mitigation was previously evaluated in model systems (glucose-asparagine), having observed up to 97.1percent acrylamide mitigation; while hydroxymethylfurfural levels increased. Canchan potato slices ~ 2 mm thick and 6 cm in diameter were immersed in EPPL solution at concentrations of 0, 1 and 2 mg AGE/mL. The impregnation was evaluated at atmospheric pressure and vacuum pressure (0.91 bar) for times of 15, 30, 60 and 120 s, and then they were fried in oil (previously heated to 180 °C) for four minutes, the content of acrylamide and color. The best results were obtained with: 1 mg AGE / mL and pressure immersion under vacuum for 120 s, 2 mg AGE/mL and pressure immersion under vacuum for 15 s, 2 mg AGE/mL or immersion at atmospheric pressure for 30 s and 60 s, obtaining 67.4, 59.3, 50.8 and 50.9 percent reduction, respectively, and a value of h* of 85.4, 78.8, 88.5 and 90.3, respectively. The results show that the best treatments (higher percentage of acrylamide mitigation) are those where the potato chips retained a greater amount of phenolic compounds and therefore greater antioxidant capacity. The results show that the purified phenolic extract of Inca Muña mitigates the formation of acrylamide, obtaining potato chips with acrylamide values lower than the maximum allowed according to international standards (EU 2017/2158)
