Acrylamide and 5-Hydroxymethylfurfural Formation in Reconstituted Potato Chips During Frying

In our present paper, the effect of water activity and processing conditions in reconstituted potato chips was considered as a model to investigate the changes of acrylamide (AA) and 5-hydroxymethylfurfural (HMF). The results suggested that the formation of AA and HMF was highly correlated with frying temperature and time. Water activity could also influence the formation of AA and HMF. Meanwhile, the formation of HMF has significant correlation with the formation of AA in reconstituted potato chips. A typical exponential growth curve was observed by plotting AA levels vs HMF content which were all determined under different heating condition: \( AA=0.002\exp \left( {\frac{HMF }{10.850 }} \right)+0.143\,\left( {{R^2}=0.850} \right) \). The model could be used as a tool for estimating the formation of AA when the content of HMF was known.
