Abstract:Abstract：In order to explore the best seasoning process of lime flavored yam chips，the best flavoring formula of lime flavored yam chips was determined by orthogonal test on the basis of single factor test.The study showed that the best flavoring formula for lime flavored yam chips was：salt 3.0%，lime fruit powder 6.0%，monosodium glutamate 1.6%，spice powder 0.12%，white sugar 4.0%.The optimum immersion time was 2 h.This research can provide a theoretical basis for the development of yam snack food.
