Fault Finding
NOTE: Excessive usage of oil is an indication of high absorption of oil into the food. This is a
function of temperature and character of the goods being fried - NOT due to type of oil
being used (unless refined oils are being used). Any variation in the apparent life of the oil
is always due to one or more of the causes mentioned above.
Fault
Possible Cause
Remedy
Oil Smoking.
Insufficient turnover of oil.
Maintain a minimum quantity of oil in fryer for more
rapid turnover or increase the quantity of food fried in
fryer. Replace with fresh oil every 3 to 5 days.
Continual frying with excess moisture on
food.
Drain foods before frying, pat food dry.
Contamination of oil.
Filter or strain daily to remove contaminants.
Overheating of oil.
Check thermostat setting with a thermometer or
thermocouple.
Rapid breakdown of oil.
Use a stable frying oil.
Use of unrefined oils.
Dripping smokes at lower temperature than refined
and deodorised oils.
Darkening of Oil.
Presence of salt on the food.
Salt foods after frying and away from the fryer.
Foods dipped in batter high in egg yolk.
Reduce egg content of batter, replace part egg with
milk.
Contamination of oil.
Filter or strain the oil daily to remove contaminants.
Poor cleaning practice.
Clean fryer at least weekly or each day in cases of
heavy usage. Ensure fryer is perfectly dry before use.
Overheating of oil.
Check thermostat setting with a thermometer or
thermocouple.
Insufficient oil turnover.
Top up daily to replace the contents of fryer in 3 to 5
days.
Cooking foods with high sugar levels.
At the end of the season, potatoes are usually high in
reduced sugars. When fried, they will darken quickly
and colour the oil.
