Due to the high temperatures of deep frying food, the cooking oil used in your Electric Deep Fryer will over time become rancid tasting.  The rancidity is caused by several factors.  They are oxidation, the formation of polymers, and acrylamide formation from starchy foods exposed to high temperatures (french fries, bread, potato chips).

These substances are toxic and for the health of your family, you should change your oil every three months or as soon as your oil starts to become rancid, whichever occurs first.

You can tell if your oil is spoiled by the following tests.

• Color: your oil turned from a light golden color to a dark brown
• Texture: your oil is thick and has a syrup like consistency
• Cooking: when you heat your oil, you get smoke or foam at the surface
• Taste: your oil has a rancid odor and taste

If any of the above is true, then it’s time to change the oil in your Electric Deep Fryer.  Of course, you can make your oil last longer and avoid rancidity by using an Electric Deep Fryer with a cover and periodically filtering your oil to remove leftover bits of starch.  The DeLonghi D895UX Cool Touch ROTO Electric Fryer is a good model which has a built in filter and cover.
