Cooking oil
is plant, animal, or synthetic fat used in frying, baking, and other types of cooking. It is also used in food preparation and flavoring that doesn't involve heat, such as salad dressings and bread dips, and in this sense might be more accurately termed edible oil.
Cooking oil is typically a liquid, although some oils that contain saturated fat, such as coconut oil, palm oil and palm kernel oil, are solid at room temperature.
Oil used in cooking foods is commonly derived from vegetables. Cooking oil is commonly used for frying. Oil used for frying is usually thrown away.
This study tried to find a way to purify used oil.

For this project you will need a
*Metal strainer
*Cheese cloth
*Paper towel
*Ginger slices ( Ginger will absorb most of the odor and taste of the foods that were cooked in the oil., about 20 grams per 1 liter of cooking oil)
* Airtight glass jars or bottles for storage
This process for filtering and reusing cooking oil requires the oil to be heated, so avoid using anything made of plastic throughout the procedure and make sure none of the things used during the procedure are moist or wet.
Strain the cooking oil once using a strainer to catch and remove any coarse food particles.
Heat the oil to a temperature of about 170 -200 degrees Fahrenheit, and put in the ginger slices.
Turn off the heat after about two or three minutes, and let the ginger slices remain in the cooking oil while the oil cools naturally.
When the cooking oil has cooled down to about 120 degrees Fahrenheit, which will be approximately 10-15 minutes after turning off the heat, it’s time to filter the oil.
To make the filter, line the conical strainer with the paper towel, making sure that there is no place from where the oil can leak out without passing through the towel. Next, line it with the cheese cloth in the same fashion. Since the filter we’ve made is really fine, it may take few minutes for one litre of oil to pass through it.
When the filtered oil reaches room temperature, you can transfer it to the storage jars. Close the lids tightly and store them in the refrigerator.
This procedure can be repeated three to four times before you finally need to discard the fryer oil, which means a little effort can save you some goodly amount of money too.
Alternatively if you are recycling small oil volume, you may boil it with equal parts water the let it cool. The water will collect the impurity's. Then all you have to do is remove the oil from the top of the water.

Because of heating the oil is then sterilized and now only the coarse particles and odors of the previously cooked substances of the oil remain. But that problem is solved due to the ginger slices present in the process.

Detail 3

This investigatory project determines the possibility
of purifying used cooking oil. Our group was brainstorming some
ideas and we came up with something simple, efficient and great
for the community. What if we could reuse the cooking oil we use to avoid purchasing more expensive oil and get the maximum benefit of it?
This project would help us since it will make people spend less for cooking therefore minimizing the manufacturing of oil and preventing harmful smoke to our atmosphere due to the processing of such.
