How many times can I use frying oil without changing it?
Fryolator oil service life depends on many factors: the fryolator model (conveyor, open/closed type, with or without oil filter), the type of product fried (French fries, chicken, buns, etc.), the process temperature which differs for frying different products, i.e. at least 175°С for chicken drumsticks or 160°С for french fries, the frying time that depends on the product weight and finishing stage. So, fryolator oil service life is different for each individual product. The end of frying oil service life is estimated using test strips that detect the free fatty acids content level. Free fatty acids (FFAs) degrade the product quality making it taste and smell bad. Test strip indicator helps assess the free fatty acids content level and therefore, tell how suitable for further use the oil is. A polar compound metering machine can also be used. Polar compounds are degradation products generated by deep frying foods. High polar compound content oil usually is rich in acrylamide, a carcinogen substance.
