When to change deep-frying oil?

Deep-frying oil should be changed in a timely manner if it has an unusual colour or odour (e.g. a rancid smell), starts to smoke or starts to foam. Do not add fresh oil to used oil for diluting! Aim for a yellow golden colour when frying food to reduce the formation of carcinogenic contaminants.

Remember: Do not dilute waste oil with fresh oil.
