5-hydroxymethylfurfural and flavan-3-ol

5-Hydroxymethylfurfural (HMF) is regarded as a thermal process contaminant in foods. Six flavan-3-ol fractions were isolated or semisynthesized from sorghum, cranberry and grape seed. Their unit compositions, interflavan linkages and degree of polymerization were characterized. The aim of this study was to investigate the effect of flavan-3-ols on the formation of HMF in chemical reaction models and fried potato chips.. Results showed that all flavan-3-ols significantly mitigated the HMF formation at concentrations of 50, 100 and 200 µg mL. This study demonstrates that flavan-3-ols could be effective additives for reducing HMF levels in fried potato chips without changing sensory properties. © 2018 Society of Chemical Industry.
