Furthermore, acrylamide formation in French fries was examined in relation to different nitrogen fertilization strategies and potato strip size. Frying potato slices at 160°C for 7 min mitigated the acrylamide formation in potato chips processed from Atlantic, Snowden and Vigor varieties by 84, 67 and 78%, respectively, compared to potato slices fried at 190°C for the same frying time. The most effective reduction (19-59%) was obtained when potato slices were blanched in distilled water for 5 min at 65ºC. This study showed that different nitrogen treatments can affect the formation of acrylamide in French fries and its precursor contents in potatoes. Decreasing the surface-to-volume ratio by creating thicker potato strips reduced acrylamide content in French fries processed from Russet Burbank, Ranger Russet, and Shepody varieties.
