What’s more, long processing time needs more fuel and electricity increasing investment. The best blanching time for frozen french fries is 7-15 minutes in 70℃. For different amount of potatoes, the blanching time and water temperature can be adjusted.

The oil content in french fries will increase heavily when potatoes are fried in low temperature in short time and high temperature in long time.
