What is TPM of oil?
Total Polar Materials (TPM) refers to all products present in frying oil due to oxidation processes, including free fatty acids, products of low molecular weight decomposition, and polymerized substances.
How do you check oil TPM?
The frying oil test is extremely easy with the testo 270 cooking oil tester:
- Remove the fried product and wait until there are no more bubbles visible in the oil.
- Switch on the cooking oil tester.
- Immerse the cooking oil tester in the hot oil and measure.
- Read off the TPM value – job done.
How is TPC formed in oil?
Total polar compounds (TPC) whose polarity are larger than those of triglycerides, are generated from peroxides and hydroperoxides during continuous frying, including short chain fatty acids, aldehydes, ketones, alcohol and nonvolatile products [1].
How often should you change oil in fryer?
Most oils should be changed after eight to ten uses. You need to remove oil from the deep fryer after each use, strain it and store it correctly until the next time. A good tip: keep the filtered oil (food residue left in the oil will give it a bad taste) in a cool, dark place until the next use.

How do you determine the number of polar compounds in oil?
TUV India uses column chromatography with a method based on AOAC to analyse the amount of total polar compounds in cooking oil. The chromatography technique is based on adsorption which achieves both total polar and non-polar compounds separately by applying different organic solvents.

What are polar compounds?
Polar compounds are chemical compounds that are held together by polar covalent bonds. The term ‘polar compound’ can be defined as a chemical species which consists of two or more atoms that are held together by covalent bonds that are polar in nature due to the unequal sharing of electrons.
Why do oil and water never mix?
Oils and fats not have any polar part and so for them to dissolve in water they would have to break some of water s hydrogen bonds. Water will not do this so the oil is forced to stay separate from the water.

Which bond is non polar?
polar covalent bond
A non-polar covalent bond is a type of chemical bond that is formed when electrons are shared equally between two atoms. Thus, in an atom, the number of electrons shared by the adjacent atoms will be the same. The covalent bond is also termed as nonpolar because the difference in electronegativity is mostly negligible.
