This study investigated the use of different frying methods, including deep fat frying, microwave frying, air frying, and vacuum frying, to reduce the formation of acrylamide (AA) and hydroxymethylfurfural (HMF) in French fries. The highest reduction in AA and HMF content was observed in vacuum frying (61.42-81.14%), followed by air frying (59.2-78.7%), compared to deep fat frying and microwave frying. Samples fried using these methods also had significantly lower browning index (BI) and CIE a* values. Principal component analysis (PCA) demonstrated that vacuum frying and air frying were alternative technologies for minimizing AA and HMF content in French fries.
In this study, deep fat frying, microwave frying, air frying, and vacuum frying processes were used to mitigate acrylamide (AA) and hydroxymethylfurfural (HMF) formation during the frying of French fries. The highest reduction of AA and HMF range was found in vacuum frying (61.42-81.14%), followed by air frying (59.2-78.7%), as compared to deep fat frying and microwave frying. Both these method samples also showed significantly (p < 0.05) lower browning index (BI) and CIE a* values. Principal component analysis (PCA) was used to visualize the effects of the different frying methods on AA and HMF content. Vacuum frying and air frying were found to be alternative frying technologies to minimize AA and HMF content in French fries.
