Abstract:
Acrylamide (AA), a carcinogenic compound formed during the heating of food, is prevalent in carbohydrate-rich foods. Herein, A ring-type polyphenols (phloroglucinol, PHL), catechol B ring-type polyphenols (4-methylcatechol, 4MC and chlorogenic acid, CQA), and A and catechol B rings-type polyphenols ((+)-catechin, CAT and (-)-epicatechin, EC), were evaluated on the effect of AA in equimolar asparagine/glucose Maillard model systems. The results indicated CAT promoted the formation of AA, whereas CQA, 4MC, EC and PHL exhibited an inhibitory effect. High resolution mass spectrometry (UPLC-Q-Exactive Orbitrap MS/MS) was applied to further investigate their influencing pathways on AA. Four products were identified by extracted ion chromatography and MS spectrum. A ring-type PHL and catechol B ring-type polyphenols mitigated AA generation by binding intermediate products. A and catechol B rings-type polyphenols demonstrated different impacts due to different spatial structures. These findings provide a new perspective to take the utilization of polyphenols on AA mitigation.
