Can vegetable oil go bad

Answer 1

If you push it too far.

Yes, vegetable oil, olive oil, peanut oil, canola oil, lard and shortening can turn or go 'bad' and produce an off odor and taste to food.

If it goes cloudy then it will not effect the taste when cooked.

Answer 2

Usually the smell will give it away. Rancidity has an acrid, unpleasant odor.

Next would be the flavor. There's an odd sharpness that leaves a bad aftertaste.

If the oil has been around too long, you are better off getting some fresh product. Rancid oil will ruin your food and it won't be salvageable.

Answer 3

There are several ways to determine if cooking oil has deteriorated. First, there will be an odor that is quite strong - it will be obvious if the oil has gone foul.

Second, if the oil begins to smoke soon after applying heat to it, that could be an indicator that the oil has become saturated with suspended matter that will not further settle, and is burning. This will give the oil a dark color, and will also contribute to the stink.
