This study showed that acrylamide content in potato chips is
affected by potato cultivars. Selection of chipping potato cultivars
with low reducing sugar would greatly reduce the acrylamide
content in potato chips. Compared with traditional frying (atmospheric
conditions), vacuum frying reduced acrylamide formation
in potato chips dramatically by about 94%. Vacuum frying potato
slices at 118 °C produced potato chips with low acrylamide content
and desirable yellow golden color and texture attributes compared
with those fried in the traditional fryer. The frying oil temperaturetime
combination also affected acrylamide formation significantly
in the potato chips. For the 2 treatments studied, acrylamide
formation decreased significantly in potato chips as the frying temperature
decreased from 180 °C to 150 °C for the traditional method
and from 140 °C to 118 °C for the vacuum frying.
