Before cleaning the fryer, the cooking oil must be cooled below 250°F (121°C) before draining. Failure to do so may cause “thermal shock” damage to the fryer. With normal oil cooling, it takes 1.5 to 2 hours for the oil to drain safely.
How do you cool down boiling oil?
One way to do this is to fill a large container with water only and then add ice to the area surrounding the sides of the oil container. The water also helps conduct heat from the underside of the oil container to the ice.
What happens when oil is boiled?
Repeated heating can cause changes in the physical appearance of the oil, such as increased viscosity and darker color [1], and can alter the fatty acid composition of the oil. Upon heating, oil undergoes a series of chemical reactions such as oxidation, hydrolysis, and polymerization [2].
How do you know when oil is boiled?
How to determine oil temperature The easiest and safest way is to poke the tip of a wooden spoon into the oil. When many bubbles form around the wood and begin to float, the oil is ready to fry. If there is too much bubbling, the oil is too hot. Allow it to cool slightly and check the temperature again.
How do you cool oil after frying?
When you are sure the oil has cooled to room temperature, come back. Pour the used oil through a fine sieve lined with several layers of cheesecloth. This will help catch any fine material left over after the initial frying .
What do I do if my grease is too hot?
Carefully pour an appropriate amount of baking soda over the grease fire. OR…soak a towel under the faucet, squeeze out any excess dripping water, and hang it over the burning grease pan to smother it. (This is very effective, quick and easy!)
Can you use overheated oil?
Cooking in oil heated above the smoke point not only imparts a burnt flavor to the food. The beneficial nutrients and phytochemicals found in many unrefined oils are destroyed when oil is overheated. Overheating also produces harmful free radicals.
What oil is toxic when heated?
These are oils such as soy, corn, canola, sunflower, and safflower. They are unstable fats and are not tightly bound. Because they are unstable, they can produce high levels of free radicals when heated. And as we have said before, too many free radicals in the body is undesirable.
Is cooking oil toxic?
Also, according to leading scientists, cooking with vegetable oils releases high concentrations of toxic chemicals called aldehydes. This is the result of the breakdown of fatty acids in the oil, which has been linked to diseases such as arthritis, heart disease, dementia, and cancer.
