Is it safe to use rapeseed oil in the deep fat fryer?
When you fry with oils it’s best to choose an oil with a high smoke point. The smoke point for oils is the temperature at which the oil starts to give off smoke and burn. Refined rapeseed oil, sometimes labelled vegetable oil, is a good choice of oil for deep frying, as it has a high smoke (or burn) point. See our infographic to compare the smoke points of different cooking oils. Typically refined oils have a higher smoke point than unrefined (e.g. extra virgin or cold pressed), making refined oils more suitable for frying.
NOTE – cooking oil is a highly flammable liquid:
- When deep fat frying never leave the pan unattended.
- Never pour water on a fryer that has caught alight.
- Each time oils are heated, the smoke point is reduced. It’s best to change your oil regularly, otherwise there’s a risk the oil will catch fire during cooking.
